Description

Electrical connectors, connector assemblies and contact bridge clips for connecting circuit boards

technical field

The utility model relates to an electrical connector used for connecting circuit boards, a connector device and a contact bridge clip.

Background technique

Bus plugs are known as components of terminal blocks with intelligent electronic components. In addition, bus plugs are also used to connect sensors and actuators. Each electrode of this bus plug contains two contact pieces with contact springs, and the circuit board is inserted between the contact pieces to make the conductor circuits on the circuit board contact. Typically, the two contact springs are independent of each other and are not themselves directly electrically connected to each other. Typically, a circuit board has two functions, namely to acquire a signal, or voltage, and to make an electrical connection between two separate contacts. See, for example, Phoenix Contact's support rail bus connector ME 22.5 TBUS 1.5/4P1S KMGY-2201732 with electronics housing (see Phoenix Contact's catalog "Electronics Housing 2014/2015", page 35).

If it is desired to electrically connect two contacts to each other via a circuit, it is conceivable to provide a joint contact which is stamped and formed as a one-piece metal piece and thus both sides of the joint contact are part of the same metal piece The whole is connected to each other. However, this will come with a drastic change to the terminal blocks. Such changes to terminal blocks are in turn typically associated with changes to production tooling and are therefore expensive and potentially costly.

Utility model content

Therefore, the object of the present utility model is to provide an electrical connector, a connector device and a contact bridge clip for connecting circuit boards, which can be used without or only with minor changes to the connector and the circuit board. Realize the electrical path connection between the two contacts of the contact assembly.

The purpose of another aspect of the utility model is to provide an electrical connector for connecting circuit boards, which can selectively form a path connection between the two contact pieces of the contact assembly, and the path connection can be simple and low-cost. Cost-effective implementation and reliable and flexible adaptation to customer requirements.

According to the utility model, an electrical connector for connecting circuit boards is provided. it contains

- an insulating connector housing with a housing opening into which the edge region of the circuit board can be inserted,

- first and second electrical contacts at least partially accommodated in the connector housing, which have a first edge area for clampingly holding the circuit board and for making electrical contact with at least one conductor circuit on the circuit board either a first contact shrapnel or a second contact shrapnel, and

- An electrically conductive contact bridge mountable between the first and second contact pieces, which creates an electrical pathway connection between the first and second contact pieces.

In particular, a circuit board is a printed and assembled circuit board with electronic components, such as SMD components, which is sometimes also referred to as a printed circuit board or PCB (printed circuit board).

The circuit board has first and second planar sides, which may also be referred to as front and rear sides. In particular, the printed circuit board has printed conductor circuits and electronic components on at least one of the two planar sides, optionally on both planar sides.

The electrical connector has an insulating connector housing, preferably a plastic housing, which has a housing opening into which the printed circuit board can be inserted by its end face with its edge region. In addition, the electrical connector has a first electrical contact piece with a first contact spring and a second electrical contact piece with a second contact spring, when the circuit board is inserted into the connector through its edge region, the two contacts are at least partially It is accommodated in the connector housing and is configured to clamply hold the edge region of the circuit board and contact at least one conductor circuit on the circuit board.

In addition, the connector according to the present invention also has a contact bridge with conductive capability that can be independently used between the first and second contacts, which directly establishes a direct connection between the first and second contacts. Electrical pathway connection.

An advantage of the present invention is that the electrical path connection can be completed independently of the direction of the conductor circuit of the circuit board and the electronic equipment.

It can be seen that the plug-in connector can have a plurality of combinations of first and second contacts with first or second contact springs, which can contact a plurality of conductor circuits arranged next to each other and can be contacted by means of contact bridges. The clips enable the conductor circuits to be connected via paths respectively. The circuit board may have slots between the conductor circuits so that the conductor circuits extend over a protruding or clawed portion of the circuit board which in turn inserts into the connector. In this case, the housing opening can be divided by means of separating walls which protrude into slots in the circuit board between the projections. However, the circuit board can also have a smooth end face for insertion into the connector.

In an advantageous manner, the utility model realizes the optional formation of the path connection, that is, whether the conductor circuit path should be connected or not, without or only slightly adjusting the connector or the connector housing and the circuit board. . This can be determined by the customer and for this purpose only requires the use of contact bridges in the corresponding contact cavity between each contact combination. This can be less expensive and less expensive than having to prepare a new tool to manufacture the changed connector. In an advantageous manner, the user can even selectively set the contact bridges for each contact only by correspondingly using the contact bridges on the desired contact combinations and not using the contact bridges on conductor circuits that do not wish to form via connections. Each conductor circuit independently selects whether to form a via connection. The use of the contact bridge clips can be done by the connector manufacturer or even by the user after the rest of the connector is fully assembled. Therefore, the present invention realizes a flexible structural solution for the user, that is, no need to adjust the circuit board design and no or only slight changes to the connectors.

The connector is preferably, for example, a bus plug or a bus plug connector for connecting actuators or sensors, in particular a bus connector of the type on which a plurality of bus plug connectors can be arranged in a chain with one another in a row , such as rail bus connectors. In this case, the lower contact springs of a plurality of bus plug connectors arranged in a row contact each other, ie continuously from one bus plug connector to the next bus plug connector. For this purpose, a via connection between the respective first and second contact pieces within the bus plug connector is particularly advantageous, since this is based on a via connection between all bus plug connectors, bus plug connector to bus plug connector Via connections can be formed for individual subcontact combinations.

According to a preferred embodiment of the contact bridge, it has a first contact lug and a second contact lug as well as a transverse support connecting the first contact lug and the second contact lug to one another. When the edge area of the circuit board is inserted into the connector, one side of the first contact piece is close to the first contact spring, the other side is close to the first plane side in the edge area of the circuit board, and one side of the second contact piece The other side rests against the second plane side in the edge region of the circuit board against the second contact spring. Thus, when the edge region of the circuit board is inserted into the connector, the edge region of the circuit board is clamped between the first contact lug and the second contact lug. In other words, when the circuit board is inserted into the connector, it is guided between the two contact lugs and, in the fully inserted state, the edge area of the circuit board insertion is clamped on both sides and held in a friction fit between the first and second contacts. Between the pads, wherein the first and second contact pads are opposite each other with respect to the circuit board. At the same time, the metal contact piece is also used for the electrical contact of the circuit board. The conductor path to be contacted thus extends over the edge region of the printed circuit board, more precisely as far as between the first and second contact lugs. The first and second contact springs are preferably formed by the first or second, especially U-shaped metal contact piece, and the U-shaped metal contact piece can realize the separate adjustment of the distance between the two connectors.

Then, in an advantageous manner, the contact bridge clips can be inserted into the first and second contact bridges in a simple manner after the connector has been completely assembled, by the manufacturer or by the user through the housing openings defined for insertion into the circuit board. The contact cavity between the shrapnel, and optionally put into the desired contact cavity corresponding to the selected conductor circuit to be connected through the channel.

In addition, the first contact spring and the second contact spring exert a normal force perpendicular to the plane of the circuit board according to their deflection respectively. Preferably the respective first contact piece and the second contact spring transmit the normal force exerted by the corresponding first contact spring and the second contact spring onto the edge region of the circuit board, thereby clampingly holding the edge region of the circuit board in the Between the first contact piece and the second contact piece, however, this normal force originates from the contact spring.

In other words, the first and second contact lugs contact the first or the second plane side of the circuit board and obtain as limited as possible a usability only due to the deflection of the contact springs perpendicular to the plane of the circuit board against the spring pretensioning force. The normal force on the contact circuit board. For this purpose, the corresponding contact piece preferably rests flat against the corresponding contact spring.

The contact bridges therefore preferably themselves do not need to generate substantial spring forces, which advantageously enables the contact bridges to be produced from a relatively thin and soft sheet metal. The contact bridges are designed as metal parts stamped and formed from sheet metal. Thus, the contact bridge can be designed, for example, as a stamped and formed metal part from copper or a copper alloy. This has the advantage that a high electrical conductivity of the contact bridge is ensured even with a small conductive cross-section.

The thickness of the metal sheet is preferably 0.1 mm to 0.5 mm.

As a result, the contact bridge can at the same time be designed small enough with low contact and transfer resistance values that it can be used as an optional additional variant without changing or only slightly adjusting the connector. in the existing connector. With such suitable dimensions for the contact bridges, both the connector housing and the contact piece with the aforementioned contact springs can continue to be used, if necessary, unchanged. Nevertheless, the normal force of the contact shrapnel was not increased to impermissible levels.

According to the utility model, the contact bridge clip has a first contact piece and a second contact piece and a transverse bracket connecting the first contact piece and the second contact piece to each other, wherein when the edge region of the circuit board is inserted into the connector, the second contact piece One side of a contact piece is close to the first contact elastic piece, and the other side is close to the first plane side in the edge area of the circuit board, and/or the second contact piece is close to the second contact elastic piece on one side, and the other side is close to the second contact piece. Adhesive on the second plane side in the edge region of the circuit board, so that the electrical contact of the first contact spring or the second contact spring to the conductor circuit is obtained via the first contact lug or the second contact lug.

When the edge area of the circuit board is inserted into the connector, the first contact piece is close to the first contact spring with its outer side, and directly against the first plane side of the edge area of the circuit board with its inner side, and the second contact The sheet is in close contact with the second contact spring with its outer side and directly with the second plane side of the edge region of the circuit board with its inner side, so that the first or second contact spring is connected to the conductor through the first or second contact sheet. circuit electrical contact.

Accordingly, the corresponding contact lugs advantageously form a good, flat connection between the conductor circuit and the contact springs, so that the electrical properties of the connector used do not deteriorate to an impermissible level, and at the same time the desired via connection is also ensured. Has small contact and transfer resistance values.

According to the preferred design scheme of the contact bridge clip, the first contact piece and the second contact piece extend from the connecting plate to the same direction as the corresponding first contact elastic piece and the second contact elastic piece, and the connecting plate is connected to the first contact piece and the second contact piece. The two contact pieces jointly form a Y shape in side view. The transverse bracket contacting the bridge clip integrally connects the two connecting plates to each other at the fork of the Y shape, and then the first contact piece and the second contact piece of the connecting plate are separated from each other at the bottom of the Y shape and bent to fit again. The contact bridges can thus advantageously be stamped and formed from sheet metal, can advantageously be used between the contact springs and be adapted in an advantageous manner to the shape of the existing contact springs.

The contact bridge preferably has a locating piece which can be locked with corresponding locating pieces of the first and second contacts, thereby fixing the contact bridge in the connector.

Advantageously, it is possible, for example, to punch out projections on the connecting plate, which lock into holes on the contact pieces, for example on the cantilever arms of the two contact springs. This enables reliable positioning directly with the metal contact on the flat structure.

It is also preferred that the contact bridges have outwardly extending tabs, which may additionally engage in the plastic connector housing in order to secure the contact bridges in the connector. As a result, a reliable, play-free mechanical connection between the contact bridge and the connector housing can likewise be produced in an advantageous manner.

The clips advantageously extend substantially in the direction of the plane of the circuit board, but a slight oblique curvature thereof should not be excluded. Preferably, the fixing pieces protrude integrally from the two connecting pieces along the plane direction of the circuit board, and protrude from the transverse bracket along the vertical direction of the plane of the circuit board. In an advantageous manner, this can be stamped and formed well on the one hand and securely held in the connector housing on the other hand.

Furthermore, the clips advantageously at least partially have clip teeth on the end side, which engage in the plastic material of the connector housing when the contact bridge clip is inserted into the connector housing. In an advantageous manner, this connection is play-free and the connector housing does not have to be changed. However, it cannot be ruled out that the connector housing is at least partially equipped with provided recesses or recesses for positioning.

The contact bridge clip preferably has side guide pieces, which come into contact with the side edges of the contact piece and/or the contact spring pieces when the contact bridge clip is inserted between two contact spring pieces. In an advantageous manner, the contact bridges are thus precisely positioned on the contact springs, so that it is possible to ensure that, on the one hand, between at least one contact lug and the conductor circuit, and on the other hand, between at least one contact lug and the corresponding contact dome. high-quality contacts.

According to the utility model, the contact bridge clamp has a side guide piece and/or a fixed piece, which cooperates with the edges of the first contact elastic piece and the second contact elastic piece and/or the first and second contact pieces, so that the contact bridge The shape clip is positioned on the first contact elastic piece and the second contact elastic piece.

Furthermore, the subject matter of the present invention relates to a connector device comprising an electrical connector and a circuit board which is inserted with an edge region into the opening of the connector housing, wherein the circuit board is held clampingly on the first contact bridge. Between a contact piece and a second contact piece, and here, at least one conductor path on the circuit board is in direct electrical contact with the first contact piece or the second contact piece.

Another main body of the utility model is a contact bridge clip, which is used for the electrical connector according to the utility model, and the contact bridge clip is used for installation through the housing opening of the connector housing of the electrical connector, And if necessary by means of the disclosed preferred development, the contact bridge is used to manufacture the first and the second contact when the contact bridge is fixed in the connector housing between the first and the second contact Electrical path connection between.

Furthermore, the subject of the present invention is the application of one or more such contact bridge clips in the connector to insert and contact the circuit board, wherein the contact bridge clips are selectively seated in the housing opening of the connector housing. Interposed between corresponding first and second contact members disposed oppositely in contact with conductor circuits on the circuit board to selectively make via connections between selected combinations of first and second contact members.

Detailed ways

Referring to FIGS. 1 and 2 , in this example the connector 10 is designed as a bus plug or bus connector and has a plastic connector housing 12 with a housing opening 13 through which a circuit board 20 is inserted into the edge region. 22 (see Figures 5 and 10) into the housing opening.

The first contact 28 includes a punched and formed first contact spring 32, the second contact 30 includes a punched and formed second contact spring 34, and the circuit board 20 is generally clamped therebetween and forms an electrical contact. touch. The connector 10 has a total of several further contact pieces 28 , 30 arranged next to one another—in this example a total of four of each kind—for contacting the conductor path 26 in each case.

The circuit board or printed circuit board 20 has four contact claws 24 in the insertion edge region 22 , on which the conductor tracks 26 run. The contact claws 24 are separated from each other by slots 23 on the circuit board 20 (see Fig. 10).

Referring to Figures 3 to 8, the contact bridge 40 is stamped from thin metal sheet and formed into a metal strip. The contact bridge 40 has first and second contact lugs 402 , 404 , which extend from substantially square webs 406 , 408 in an insertion direction R—downward in FIG. 3 —of the printed circuit board 20 . The contact lugs 402 , 404 are slightly arched towards the inside at the respective underside ends of their associated webs 406 , 408 and run obliquely toward one another in the insertion direction R. FIG. The bent transverse strips 412, 414 (on which the first and second contact pieces 402, 404 and associated connecting plates 406, 408 are hung) form a film hinge. When the circuit board 20 is inserted, the two contact pieces 402, 404 Can be bent outward. In addition, the first and second contact pieces 402, 404 also have a first or second curved contact segment 416, 418, the inner side of which is convex constitutes a first or second contact surface 416a, 418a, when assembled in place, the contact surface The first or second planar side 20a, 20b of the circuit board 20 is affixed to make direct electrical contact with a desired conductor circuit 26 on the circuit board 20 (see especially FIGS. 5 and 6 ). The first and second contact pieces 402, 404 continue to extend along the insertion direction from the first or second contact segments 416, 418 and transition into first or second end segments 422, 424 that are substantially free and smoothly terminated, as shown in FIG. In the unloaded, nearly closed state shown, they are essentially parallel, so the contact pieces are roughly Y-shaped in side view.

The first and second contact plates 402, 404 are electrically connected through the first and second connection plates 406, 408 and through the transverse bracket 410 (which integrally connects the first and second connection plates 406, 408 to each other) to make the first It is connected with the path between the second contact elastic pieces 32 and 34 . In this example, the first and second webs 406 , 408 are bent at right angles to the transverse bracket 410 , so that in the region of the webs 406 , 408 there is approximately a right-angled U-shape in a plane perpendicular to the insertion direction.

In particular, with reference to FIGS. 4 and 5 , here the contact bridge 40 is inserted into the assembled connector 10 through the housing opening 13 in the same direction as the insertion direction R of the circuit board 20 , or more precisely , into the corresponding contact cavity 15. Here, the contact bridge 40 is pushed from the end section 422 , 424 through the housing opening 14 between the first and second contact pieces 28 , 30 until the contact bridge 40 respectively reaches the associated contact set 28 , 30 between the first and second contact springs 32,34. Here, the contact pieces 402 , 404 are similar in shape and bent to the contact elastic pieces 32 , 34 , so that they can be smoothly attached to the contact elastic pieces.

In this example, the contact bridge 40 is integrally stamped and then formed from a 0.2 mm thick copper sheet. Accordingly, the contact pads 402 , 404 are relatively soft and do not themselves exert, or at least do not exert, a large contact force against the planar sides 20 a , 20 b of the circuit board 20 . In the example shown, the reference thickness of the circuit board 20 is 1.02 mm. The contact force is substantially exerted by the existing contact springs 32 , 34 and transmitted via the contact blades 402 , 404 substantially unchanged. Thus, as a result, existing connectors 10 can be used, since the additional deflection of the contact springs 32 , 34 caused by the material thickness d of the contact blades 402 , 404 is still within the permissible range.

In particular, as can be seen in FIG. 6 , the contact bridge clip 40 constitutes an electrical contact bridge between the first contact spring 32 and the second contact spring 34 via a transverse bracket 410 , thereby creating an electrical path between the two contact springs 32 , 34 connection, and this connection has nothing to do with the circuit board 20, and the two contacts 28, 30 are not otherwise connected to each other.

The contact bridge 40 has a first and a second clip 432 , 434 , which extend entirely outwardly from the first or second web 406 , 408 transversely to the insertion direction R. As shown in FIG. Here, the first and second clips 432 , 434 are slightly inwardly bent, that is to say bent towards each other, and have clip teeth 442 at their respective free ends, which when the contact bridge clip 40 is inserted into the connector housing 12 At the same time, the clip teeth are embedded in the plastic material of the connector housing 12 .

In particular, referring to FIGS. 4 and 8 , the contact bridge clip 40 also has a third clip 436 extending outwardly from the transverse bracket 410 in an opposite direction transverse to the insertion direction R. Referring to FIGS. Preferably, as can be seen in FIG. 8, the third clip 436 is bent upwards, that is to say, bent against the insertion direction, and, in this example, by about 60°, so that when the contact bridge clip 40 is inserted into the connector When housing 12, the third clip is embedded in the plastic material of connector housing 12 by its free stamping edge 436a, and here cooperates with the first and second clip 432, 434 that is positioned at the opposite side, in the housing A certain tension is generated in the opening, and the contact bridge 40 is fixed more reliably in the connector housing 12 not only by means of a force-fit connection, but even by means of some form-fit connection. However, this method should not be excluded, that is, the connector housing 12 is specially provided with corresponding grooves or other positioning devices, and the clips 432, 434 and/or 436 cooperate with them to fix the contact bridge clip 40 more reliably. in the connector housing 12 .

In particular, referring to FIGS. 3 and 7 , the contact pieces 402 , 404 also have lateral guide pieces 452 , 454 extending outward transversely to the insertion direction R. Referring to FIGS. The guide strips 452, 454 are transverse to the plane of the metal sheet, and are bent opposite to each other in a direction away from the side edges 402a, 404a of the contact strips 402, 404, so that the first and second contact elastic strips are surrounded by the sides, resisting lateral thrust, and laterally upward The guide contact bridge clip 40 is attached to the contact springs 32 , 34 . Furthermore, the contact bridge 40 has a first and a second fastening lug 456 , 458 on the upper side of the web 406 , 408 opposite the contact lug 402 , 404 , which are likewise bent outwards transversely to the direction of insertion R, so that when When the contact bridge clip 40 is pushed into the contact cavity 15, a stop means is formed on the respective upper edge 28a, 30a of the first or second contact piece 28, 30.

Furthermore, the contact bridge 40 has a first and a second projection 462 , 464 formed outwardly from the first or second web 406 , 408 transversely to the insertion direction R, which are positioned on the first or second contact piece. 28,30 in the first or second through hole 466,468.

Referring to FIG. 9 , any number of bus plugs 10 may be arranged next to each other, wherein the bus plugs 10 whose respective first and second contacts 28 , 30 are adjacent to each other are electrically connected to each other. The first contact piece 28 has an outer contact surface 66 on the side opposite to the first contact elastic piece 32 on the U-shape, and the second contact piece 30 has an outer bus contact on the side opposite to the second contact elastic piece 34 on the U-shape. Shrapnel 68. The outer bus contact elastic piece 68 and the outer contact surface 66 can be approached from the outside of the connector housing 12, and the outer bus contact elastic piece 68 and the outer contact surface 66 are realized by respective adjacent bus plugs 10 connected to each other, so as to realize The electrodes to which the bus plugs 10 belong to which are arranged adjacent to each other in a chain are connected by chain vias.

Referring again to FIGS. 4 and 8 , the user (for example, a customer of a connector manufacturer) can choose for himself which electrodes, or conductor circuits 26 , of the circuit board 20 should be connected via the contact bridge clip 40 . The user can decide for each individual conductor circuit 26, or in other words, each pair of individual contact springs 32, 34 and each individual circuit board 20, whether a contact should be used between its contact spring assembly 32, 34 according to its own judgment. bridge clip. In other words, the contact bridge clips 40 are selectively used in the corresponding contact cavities 15, ie where and only where they are needed, thereby forming a gap between bus plugs 10 arranged next to each other as shown in FIG. access connection. As can be seen in FIG. 8 , no contact bridge clips 40 are used in the two contact cavities 15 on the right and, therefore, these electrodes are not via-connected. Overall, the invention offers the user the advantage that he can selectively decide which conductor circuits 26 are to be provided and which are not to be provided with a via connection simply by using the contact bridge 40 .

To sum up, the connector 10 can be completed by means of an additional contact bridge 40 , so that it can be connected or conduct signals or voltages without the participation of the conductor circuit 20 . For this purpose, a contact bridge 40 or bus contact fork is inserted into the contact cavity 15 of the assembled connector 10 or bus plug. The contact bridges 40 are designed such that the assembled bus plug 10 can optionally be used without structural changes. Although, as can be seen in FIG. 8 , the housing has a recess for the third clip 436 , this recess is not mandatory and can also be provided generally in all contact chambers 15 . The contact bridge 40 can be inserted into the assembled connector 10 or bus plug both at the supplier and at the customer. The contact force is essentially generated by the existing contact springs 32 , 34 . This enables the possibility to select flexible metals with higher electrical conductivity if necessary. The contact force is higher than the case without a via connection or without via conduction by a certain amount of force, ie a force caused by a greater amount of compression of the respective contact springs 32, 34 due to their material strength. In an advantageous manner, however, the bus plug 10 embodied in its most common form does not need to be changed, that is to say, the connector does not need to be deformed whether or not a via connection is provided at a particular contact combination 28 , 30 . Furthermore, the connector 10 offers the customer a high degree of flexibility, since, in the most common embodiment, the customer can decide for himself by selectively using the contact bridge clips whether the corresponding contact point should be via-connected, that is to say whether disconnect. Other than that, the circuit board 20 can be used unchanged.

It will be known to those skilled in the art that the above implementation forms are examples, and the utility model is not limited thereto, but can be changed in various ways without exceeding the scope of protection of the claims. It can also be seen that a feature also defines an individual basic component of the invention, even when it is described together with other features, regardless of whether the feature is disclosed in the description, claims, drawings or otherwise. In addition, it can be seen that the features related to the connector device, the circuit board and/or the contact spring are all disclosed, and the features are also disclosed alternately for other corresponding main bodies in the present invention.
