Description

Connector {Connector}

The present invention relates to a connector.

Connectors perform electrical connections by combining with mating connectors, and perform signal connections in various forms. Such connectors and mating connectors are male connectors and female connectors, and the terminals inside combine with each other to perform signal connections.

When performing an electrical connection between connectors, waterproofing is required, so a seal is installed between the connectors to be mated to prevent water from entering. In this way, when the seal is positioned between two connectors, if the connectors to be mated are not in a straight line and one connector is tilted relative to the other connector, there will be parts where the seal is pressed and parts where it is not pressed, and waterproofing will not be performed properly. This tilting of one connector relative to the other connector can occur when an external force is applied to a cable extending from the connector.

If the connectors on one side and the connectors on the other side are not connected in a straight line, the connection between each terminal will not be made properly, and there is also the problem of severe vibration and noise generation.

In addition, there is a problem in that the waterproofing function is lost because the seal that acts as a waterproofing element between the connectors is pushed during the mating process of the connectors, preventing the seal from being installed accurately between the connectors.

Therefore, it is necessary that the connectors that are coupled with each other and electrically coupled between the terminals are coupled so that the connectors are aligned exactly in a straight line in the direction of coupling and disengagement, and that this coupled state is maintained.

A step is formed on both sides of the sealing portion surrounding the above connecting pipe, and the outer diameter of the step on the free end side of the above connecting pipe may have a smaller value than the inner diameter of the internal space of the mating connector.

The connector according to the present invention can have at least one of the following effects.

In the present invention, the overlapping portion of the first connector is configured to be in close contact with the inner surface of the second internal space of the second connector. That is, the overlapping portion allows parts of the first connector and the second connector to be in a press-fit state with each other, thereby suppressing vibration generation between the first connector and the second connector, and allowing the seal to be positioned more accurately, thereby providing the effect of more accurately performing the waterproofing function.

The connecting pipe end in the shell housing of the first connector is positioned deeper than half the length of the second internal space of the second connector, and there is a predetermined gap between it and the inner surface of the second internal space. Accordingly, the coupling between the first connector and the second connector becomes easier, while the generation of vibration is reduced.

In the present invention, the connecting tube of the first connector is designed to have a predetermined gap with respect to the inner surface of the shell internal space of the shell housing. Accordingly, there is also an effect of relatively reducing the insertion force when the first connector and the second connector are coupled.

In the present invention, when the ground contact of the first connector and the ground contact of the second connector are coupled with each other, vibration due to relative movement is prevented. To this end, a reinforcing bead is placed at a position relatively closer to the front of the ground contact than the elastic contact projection of the contact lever of the ground contact of the first connector. Accordingly, the coupling state between the ground contacts is made solid by the reinforcing bead, so that vibration is prevented.

In the present invention, a cap is provided at the rear of the shell housing to shield the internal space of the shell. A capsule is provided between the cap and the shell housing. The capsule serves as a waterproofing and insulating agent, and enables the cap to be firmly fixed to the shell housing. In particular, the capsule absorbs various environmental changes, such as temperature changes that occur during use of the connector, so that the mounting state of the cap is firmly maintained.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When adding reference numerals to components in each drawing, it should be noted that the same components are given the same numerals as much as possible even if they are shown in different drawings. In addition, when describing embodiments of the present invention, if it is determined that a specific description of a related known structure or function hinders understanding of the embodiments of the present invention, the detailed description thereof will be omitted.

In addition, when describing components of embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components are not limited by the terms. When it is described that a component is "connected," "coupled," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but another component may also be "connected," "coupled," or "connected" between each component.

Hereinafter, the configuration of a connector of an embodiment of the present invention and a connector assembly having the connector will be described with reference to the attached drawings.

In Fig. 1, a first connector (10) is disclosed. The first housing (11) can form the appearance of the first connector (10). A terminal unit (20) to be described below can be coupled to the first housing (11) to form the first connector (10). Here, the first housing (11) can be replaced with one having various shapes in consideration of coupling with the second connector (60), which is a counterpart connector. Accordingly, the terminal unit (20) can be used as is, and the first housing (11) can be replaced with one having a different configuration, such as a key code, in consideration of coupling with the counterpart connector.

The first housing (11) above can be made of an insulating material. The first housing (11) can be made of an insulating synthetic resin material. The first housing (11) can be made by injection molding. There is a through space (12) penetrating the first housing (11) in the front and rear directions. The terminal unit (20) and a part of the second connector (60) can be inserted and positioned in the through space (12). The through space (12) is formed to penetrate the first housing (11) in the front and rear direction, and the terminal unit (20) can be inserted into the through space (12) from the rear of the first housing (11). As can be seen in FIG. 2, a catch (14) can be formed on the inner surface of the through space (12). The above-mentioned catch (14) may be formed in multiple numbers around the inner surface of the above-mentioned through space (12). The position of the above-mentioned catch (14) corresponds to the catch channel (26) described below.

The first housing (11) may have a fastening lever (16) on one side of the outer surface. The fastening lever (16) is for fastening with the second connector (60). A fixing member (18) is detachably installed on the other side of the outer surface of the first housing (11). The fixing member (18) has a protrusion (not shown) that protrudes into the interior of the through-space (12), and the protrusion plays the same role as the catch (14). Before the terminal unit (20) is mounted in the through-space (12), the fixing member (18) is located at a position that is partly separated from the first housing (11), and when the terminal unit (20) is mounted in the through-space (12), the entire member can be moved so that it is in close contact with the outer surface of the first housing (10). In this way, the protrusion can protrude into the interior of the through space (12) and be placed and hung on the hanging channel (26) of the terminal unit (30).

The configuration of the terminal unit (20) is described. The terminal unit (20) may be installed, for example, at the tip of a coaxial cable (22). The terminal unit (20) may be installed in the first housing (11) to perform signal connection with the second connector (60). In addition, it may cooperate with the grounding net (not shown) of the cable (22) to perform grounding function.

The outer appearance of the terminal unit (20) may be formed by a shell housing (24). The shell housing (24) may be made of a conductive metal material. The shell housing (24) may also serve as a conductor for grounding between the second connector (60) side and the cable (22). The skeleton of the shell housing (24) may be formed by a shell body (25). The shell body (25) may form the skeleton of the shell housing (24). The shell body (25) may be made by machining a metal material.

A hanging channel (26) may be formed on one outer surface of the shell body (25). The hanging protrusion (14) of the first housing (11) or the protrusion of the fixing member (18) may be hung on the hanging channel (26). The hanging channel (26) may be formed in a circular shape. The hanging channel (26) may be formed on the outer surface of the connecting pipe (30) to be described below.

The above shell body (25) may have a cable penetration tube (28) extending in one direction. The cable (22) may be positioned to pass through the inside of the cable penetration tube (28) into the shell internal space (32) to be described below.

On one side of the shell body (25), there may be a connecting pipe (30), as shown in FIG. 3 or FIG. 9. The connecting pipe (30) may be positioned within the penetration space (12) of the first housing (11). The connecting pipe (30) may be formed to extend in the direction in which the terminal unit (20) is mounted and separated from the first housing (11). The extending direction of the connecting pipe (30) and the extending direction of the cable penetration pipe (28) may be orthogonal to each other.

A shell internal space (32) may be formed in the shell housing (24) so as to penetrate the connecting pipe (30) and the shell body (25). An inner housing (46) to be described below may be installed in the shell internal space (32). The shell internal space (32) may be opened on the opposite side of the shell body (25) where the connecting pipe (30) is located. The shell internal space (32) may also be formed by penetrating the cable penetration pipe (28). Accordingly, when viewed in cross-sectional view, the shell internal space (32) may be formed in a 'T' or almost 'ㄱ' shape inside the shell body (25). A first ground contact (40), an inner housing (46), a first terminal (50), a terminal connection port (58), a cable (22), etc. to be described below may be positioned in the shell internal space (32).

A seal mounting portion (34), an overlap portion (36), and a hanging channel (26) may be sequentially formed along the length of the connecting tube (30) surrounding the outer surface of the connecting tube (30) of the shell housing (24). A seal (35) may be mounted on the seal mounting portion (34). The seal mounting portion (34) may be a ring-shaped space, and both sides thereof may be partitioned from the surroundings by a step (34'). One of the step portions (34') may be formed around the tip of the connecting tube (30), and the rest may be formed around the connecting tube (30) at the opposite end of the seal mounting portion (34). The seal mounting portion (34) is formed between the step portions (34'). Among the above-mentioned step (34'), the one on the overlapping portion (36) side forms a surface whose upper surface is continuous with the overlapping portion (36).

Among the above-described step (34'), the one at the free end of the connecting pipe (30) has a predetermined outer diameter as a whole, and when combined with the second connector (60), a predetermined gap can be formed between it and the inner surface of the second internal space (63) of the second connector (60). That is, the outer diameter of the step (34') becomes relatively smaller than the inner diameter of the corresponding position of the second internal space (63). Here, it is preferable that the gap between the step (34') and the inner surface of the second internal space (63) have a value of 0.09 mm or less. If the gap exists in this way, the bonding force can be relatively reduced when the first connector (10) and the second connector (60) are combined.

Among the above-mentioned step (34'), it is preferable that the step located on the free end side of the connecting pipe (30) be positioned further inside than the midpoint (M) of the length in the front-back direction of the second internal space (63) (the length in the coupling/separation direction between the first connector (10) and the second connector (60)). This means that the connecting pipe (30) goes relatively deeper into the second internal space (63). The state in which the step (34') is positioned further inside than the midpoint (M) in the longitudinal direction of the second internal space (63) can be seen in FIG. 4.

The seal (35) that is seated on the seal mounting portion (34) may be made of an elastic material such as rubber, for example. The seal (35) has a cylindrical shape, and the inner diameter of the seal (35) may be slightly smaller than the outer diameter of the seal mounting portion (34) of the connecting pipe (30). Accordingly, the inner surface of the seal (35) may be installed in close contact with the outer surface of the seal mounting portion (34).

The above-mentioned overlap portion (36) is a portion that overlaps and is in close contact with the inner surface of the second internal space (63) of the second connector (60). It is a portion formed so that the outer diameter of the connecting tube (30) gradually increases. That is, in the above-mentioned overlap portion (36), the outer diameter may gradually increase from the tip of the connecting tube (30) toward the shell body (25). Accordingly, the above-mentioned overlap portion (36) may have a slope toward the shell body (25). The outer diameters at each position of the above-mentioned overlap portion (36) have different values, and the outer diameter of some sections of the above-mentioned overlap portion (36) is smaller than the inner diameter of the second internal space (63) of the second connector (60) to be described below, and in the remaining sections, it is larger than the inner diameter of the second internal space (63). Accordingly, a section of the overlap portion (36) having an outer diameter larger than the inner diameter of the second inner space (63) can be pressed into the inner surface of the second inner space (63).

A ring-shaped partition (37) may be provided between the above-mentioned overlapping portion (36) and the hanging channel (26). The hanging projection (14) of the first housing (11) may be hung on the partition (37). The hanging projection (14) may be hung on the partition (37) while being positioned within the hanging channel (26).

A cap (38) may be installed at the rear entrance of the shell internal space (32) formed in the shell body (25). The cap (38) may serve to shield the shell internal space (32) from the outside. The cap (38) may be made of a metal material. The cap (38) may have a disc shape. Of course, the shape of the cap (38) may be adapted to the shape of the shell internal space (32) being open to the rear of the shell body (25). The outer diameter of the cap (38) is slightly larger than the inner diameter at the corresponding position of the shell internal space (32). Therefore, the cap (38) may be press-fitted into the shell internal space (32).

A plurality of protrusions (38') are arranged at a predetermined interval around the outer surface of the cap (38). The plurality of protrusions (38') are arranged at a predetermined interval, so that a gap is formed between the protrusions (38'). The protrusions (38') are clearly illustrated in Fig. 13. The protrusions (38') may be slightly crushed when the cap (38) is pressed into the shell internal space (32).

A capsill (39) may be installed between the cap (38) and the shell body (25). The capsill (39) may be made of an elastic material. The capsill (39) may be made of an insulating material. The capsill (39) serves as a waterproofing and insulating material. That is, the capsill (39) may secure an insulating distance between the cap (38) made of a metal material, the first terminal (50), and the core wire (22') of the cable (22). The capsill (39) may also serve to block water from entering the shell internal space (32).

The specific configuration of the above capsule (39) is illustrated in FIGS. 13 and 14. The capsule (39) may have an overall disc shape. The capsule body (39-1) may form the skeleton of the capsule (39). The capsule body (39-1) may have a disc shape. A relatively thin connecting member (39-3) may be present surrounding the edge of the capsule body (39-1). The connecting member (39-3) is a portion that connects the capsule body (39-1) and the compression member (39-5) to be described below. The connecting member (39-3) is made to be relatively thinner than the capsule body (39-1) and the compression member (39-5). Therefore, a concave channel (39-4) may be formed in a circular shape between the capsule body (39-1) and the compression portion (39-5). The concave channel (39-4) may be formed on each of the surfaces of both sides of the capsule (39). Of course, the concave channel (39-4) may be formed on only one surface of the capsule (39). When the protruding rib (39-7) of the compression portion (39-5) described below is deformed, the deformed portion of the protruding rib (39-7) may be pushed and positioned in the concave channel (39-4).

A compression portion (39-5) may be formed surrounding the edge of the capsule (39). The compression portion (39-5) may be formed so that the capsule (39) protrudes to both surfaces. The compression portion (39-5) has a protruding rib (39-7) that is formed to protrude relatively. The protruding rib (39-7) may have an overall ring shape. One pair of the protruding ribs (39-7) may be formed on one surface of the capsule (39), and another pair may be formed on the other surface. Alternatively, the pair of the protruding ribs (39-7) may be formed on only one surface of the capsule (39).

A plane area of a predetermined width can be formed between the pair of protruding ribs (39-7). The plane area located between the protruding ribs (39-7) can have a thickness thicker at that portion than the thickness of the cap body (39-1). The protruding ribs (39-7) can be pushed while being pressed in the area between the pair of protruding ribs (39-7).

There is the following relationship between the thickness (F) of the capsid body (39-1) in the capsid (39) and the thickness (E) between the protruding rib (39-7) in the compression section (39-5). That is, the thickness of the F section can be set to be approximately 30% to 40% of the thickness of the E section. In addition, the concave channel (39-4) serves as a kind of escape space and should have a volume that can accommodate approximately 25% to 30% of the pressing amount of the protruding rib (39-7).

And, it is preferable that the degree of compression of the area between the protruding ribs (39-7) in the compression section (39-5) be between 45% and 55% of the amount of compression of the protruding ribs (39-7). That is, the protruding ribs (39-7) are mainly compressed in the compression section (39-5), and the area between the protruding ribs (39-7) in the compression section (39-5) is compressed by about 45% to 55% of the amount of compression of the protruding ribs (39-7).

As can be seen in the enlarged view of Fig. 12, when the capsule (39) having the above configuration is mounted in close contact with the shell housing (24), the compression portion (39-5) overlaps with the shell housing (24) and the cap (38), that is, when compressed, the ribs of the compression portion (39-5) are pushed out so that they can be in close contact with the cap (38) and the inner surface of the shell internal space (32). In this process, some of the ribs pushed out by the compression portion (39-5) enter the gap between the protrusions (38') of the cap (38), so that some of the capsule (39) is filled between the cap (38) and the inner surface of the shell housing (24).

Next, a first ground contact (40) may be installed within the shell internal space (32) of the shell housing (24). The first ground contact (40) may perform an electrical connection for grounding the shell housing (24) and the second connector (60). The first ground contact (40) may be made of a conductive metal material. The first ground contact (40) may be made in a cylindrical shape.

A plurality of contact levers (42) may be formed on the first ground contact (40). The contact levers (42) are formed in a cantilever shape and may be elastically deformed to a predetermined degree. The extension direction of the contact levers (42) is the longitudinal direction of the first ground contact (40). In other words, the contact levers (42) may be extended in the direction of coupling and coupling/separation of the first connector (10) and the second connector (60). An elastic contact protrusion (42') may be formed at the tip of the contact lever (42).

The above contact lever (42) can be regulated by the inner surface of the connecting tube (30) of the shell housing (24). This is well illustrated in Fig. 7. When the contact lever (42) comes into contact with the outer surface of the second ground contact (66) and is elastically deformed, the degree of elastic deformation is regulated by the inner surface of the connecting tube (30).

The first ground contact (40) may have a plurality of spacer protrusions (44). The spacer protrusions (44) are formed so that there is no gap between the first ground contact (66) to be described below and the second ground contact. The spacer protrusions (44) may be formed in a plurality. The spacer protrusions (44) may be formed to protrude inwardly from the inner surface of the first ground contact (40). The spacer protrusions (44) may be positioned closer to one end of the first ground contact (40) than the elastic contact protrusions (42'). In other words, the spacer protrusions (44) may be positioned at a position that is moved further toward the second connector (60) than the elastic contact protrusions (42'). The spacer protrusions (44) prevent a gap from being formed between the first ground contact (66) and the second ground contact (66), thereby preventing vibration due to flow from occurring.

The above first ground contact (40) is not necessarily used. Instead of the above first ground contact (40), for example, the connecting pipe (30) of the shell housing (24) may be used. The connecting pipe (30) may be provided with the contact lever (42) to directly perform ground connection.

An inner housing (46) may be installed in the shell inner space (32) of the above shell housing (24). The inner housing (46) may be made of an insulating material. The inner housing (46) may perform insulation between the first terminal (50) to be described below and the shell housing (24). The shape and size of the inner housing (46) may be designed so that it may enter the inner space (32) of the shell housing (24). A terminal mounting space (48) may be formed by penetrating the inner housing (46) in the front and rear directions. The terminal mounting space (48) may also be in the shape of a 'T' or an almost 'ㄱ'.

The first terminal (50) may be made of a conductive metal material. The skeleton of the first terminal (50) may be formed by a terminal body (52). At the front end of the terminal body (52), there may be a first coupling portion (54) that is coupled with the second terminal (64) of the second connector (60) to perform signal connection. The first coupling portion (54) may have any shape as long as it can be coupled with the second terminal (64). At the rear end of the terminal body (52), there may be a second coupling portion (56). The second coupling portion (56) may have a shape into which a cable connection port (58) to be described below can be press-fitted. However, the second coupling portion (56) may also have any shape as long as it can be coupled with the core wire (22') of the cable (22).

There is a cable connection port (58) to be connected to the second connection portion (56) of the first terminal (50). The cable connection port (58) may be cylindrical in this embodiment. The core wire (22') of the cable (22) may be compressed and connected to the cable connection port (58). When the cable (22) is connected to the cable connection port (58), it may be connected to the second connection portion (56) to perform signal connection. The cable connection port (58) may be made of a conductive metal material.

Meanwhile, the configuration of the second connector (60) that performs an electrical connection by combining with the first connector (10) and constitutes a connector assembly is described with reference to Fig. 4. For convenience, the configuration of the second connector (60) is schematically illustrated in Fig. 4.

The second housing (62) can form the exterior and skeleton of the second connector (60). The second housing (62) can be made of an insulating material. The second housing (62) can be made of an insulating synthetic resin. A part of the second housing (62) can enter the through space (12) of the first housing (11).

A second internal space (63) may be formed inside the second housing (62) into which a part of the first connector (10) is inserted. The part of the first connector (10) inserted into the second internal space (63) is a part of the terminal unit (20). The second internal space (63) may be opened toward the side into which the first connector (10) is inserted. A second terminal (64) may be installed in the second internal space (63). The second terminal (64) is electrically connected by being coupled to the first terminal (50).

A second ground contact (66) may be installed in the second internal space (63) of the second housing (62). The second ground contact (66) may be inserted into the interior of the first ground contact (40) to form a connection for grounding. The configuration for the second ground contact (66) to perform the function of a grounding point within the second housing (62) is omitted for convenience. Unexplained reference numeral 68 in the drawing is a fastening protrusion on which the fastening lever (16) of the first housing (11) is hooked.

Hereinafter, the use of a connector according to the present invention having the configuration described above will be described in detail.

The present invention configures a first connector (10) by mounting the terminal unit (20) on the first housing (11), and the first connector (10) can be combined with the second connector to transmit a signal. Here, the first housing (11) can be changed to one having a different key code, and the terminal unit (20) can be combined with other various second connectors (60) using the same one.

When the first connector (10) and the second connector (60) are coupled, the connecting tube (30) in which the seal (35) is installed in the terminal unit (20) as shown in Fig. 9 enters the second internal space (63) of the second connector (60). In the process of the connecting tube (30) entering the second internal space (63) of the second connector (60), the outer diameter of the protrusion (34') at the tip is smaller than the inner diameter of the second internal space (63), so the tip of the connecting tube (30) can be relatively easily inserted into the second internal space (63).

At this time, the seal (35) adjacent to the step (34') can also enter the second internal space (63) relatively easily. As can be seen in the drawings, since the outer diameter of the seal (35) is larger than that of the step (34'), it is in close contact with the inner surface of the second internal space (63), but since the seal (35) is seated within the seal seating portion (34), the seal (35) does not move backward. Accordingly, when the first connector (10) and the second connector (60) are connected, the seal (35) does not experience defects such as folding.

Meanwhile, when the connecting pipe (30) enters completely into the second internal space (63), the overlapping portion (36) overlaps and adheres to the inner surface of the second internal space (63) on the inner side of the entrance of the second internal space (63), as can be seen in Fig. 4. At this time, the step (34') at the tip of the connecting pipe (30) enters further inward than the longitudinal middle point (M) of the second internal space (63).

In this way, the overlapping portion (36) is pressed into and adhered to the inner surface of the second internal space (63), and the seal (35) is also adhered to the inner surface of the second internal space (63) at the longitudinal midpoint (M) of the second internal space (63), so that the portion including the connecting tube (30) of the terminal unit (20) can be firmly fixed to the second internal space (63). In other words, even if an external force is applied to the terminal unit (20), the first connector (10), particularly the terminal unit (20), is firmly fixed so that it does not move relative to the second connector (60).

In addition, the spacer protrusion (44) prevents a gap from occurring between the first ground contact (40) and the second ground contact (66). Accordingly, vibration due to relative movement does not occur between the first ground contact (40) and the second ground contact (66).

Meanwhile, the cap (38) blocks the shell internal space (32) formed inside the shell housing (24) at the rear part of the shell housing (24). The cap (38) is press-fitted into the shell internal space (32), and the cap seal (39) is positioned between the shell housing (24) and the cap (38) to firmly maintain the cap (38) mounted state.

Here, the thickness (E) of the compression portion (39-5) of the cap (38) is formed relatively thicker than the thickness (F) of the cap seal body (39-1), so that although the compression portion (39-5) is compressed by the cap (38), there is a lot of room for the thickness of the compression portion (39-5) to change even if the environment inside the shell internal space (32) changes, so that the mounting state of the cap (38) can be firmly maintained. In particular, the concave channel (39-4) in the connecting member (39-3) can have a great influence on the change in the compression amount of the compression portion (39-5).

In the above, even though all the components constituting the embodiments according to the present invention have been described as being combined as one or operating in combination, the present invention is not necessarily limited to these embodiments. That is, within the scope of the purpose of the present invention, all of the components may be selectively combined and operated in one or more. In addition, the terms "include," "compose," or "have" described above, unless otherwise specifically stated, mean that the corresponding component may be inherent, and therefore should be interpreted as including other components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which the present invention belongs, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted as being consistent with the contextual meaning of the relevant technology, and shall not be interpreted in an ideal or excessively formal meaning, unless explicitly defined in the present invention.

The above description is merely an illustrative description of the technical idea of the present invention, and those skilled in the art will appreciate that various modifications and variations may be made without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to explain it, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
