Detailed ways

The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. The specific contents listed in the following embodiments are not limited to the technical features necessary for the technical problems to be solved by the technical solutions recorded in the claims. At the same time, the enumerated embodiments are only part of the present invention, not all embodiments.

As shown in FIG1 , the connector of the present invention comprises a socket 1 and a plug 2, wherein the socket 1 has a plurality of terminal modules 5 arranged in a transverse stack. The tops of the plurality of terminal modules 5 are fixed by a clamping member 3 so as to be connected as a whole. The contact end 501 of the terminal module 5 is inserted into the socket housing 6, and the tail end 502 thereof is provided with a tail plate 4.

As shown in Figures 10, 11 or 16, 17, the terminal module 5 has two independent terminal boards 504 stacked side by side. The main part of the terminal board 504 is an insulating material, and a plurality of signal terminals 505 are injection-molded and fixed in the insulating material. The upper end of the signal terminal 505 has a contact extending from the front side of the terminal board 504 to connect the tail plate 4. The signal terminal contact 5051 at the lower end of the signal terminal 505 extends out of the terminal board 504 to connect the plug 2. The signal terminals 505 in the two terminal boards are arranged in pairs and form a differential signal pair. The sides of the two terminal boards 504 in the terminal module 5 are provided with through holes 5042 or through grooves 5043 extending from their outer surfaces to the positions of the internal signal terminals.

A first shielding member is provided between adjacent differential signal pairs in the two terminal boards 504, and the first shielding member separates adjacent differential signal pairs to achieve signal shielding to reduce or eliminate interference. The first shielding member is provided to penetrate the two terminal boards 504 at the same time, and the first shielding member is used as a supporting connector for the two terminal boards 504, so that the two signal terminals in the differential signal pair can be accurately positioned. A second shielding member for side shielding of the signal terminal 505 is provided on the outside of the two stacked terminal boards 504; the first shielding member and the second shielding member are connected and conducted and used for grounding.

In the embodiment shown in Figures 10 and 11, the first shielding member is a conductive support frame 506, which includes a plurality of metal sheets that are consistent with the length and direction of the signal terminals 505. A connection groove 5041 that penetrates the terminal board and extends along the length direction of the signal terminal is provided in the area between adjacent signal terminals 505 on the terminal board 504. Each of the metal sheets corresponds to a connection groove 5041 and is inserted therein and placed between adjacent signal terminals 505. The metal sheet passes through the two terminal boards 504 at the same time, so a shield is formed between the differential signal pairs. At the same time, due to the matching and snap connection between the metal sheet constituting the conductive support frame 506 and the connection groove 5041 on the terminal board, and the curved structure formed by the metal sheet along the arc direction of the signal terminal, the conductive support frame 506 plays a supporting and fixing role for the two terminal boards 504, which can maintain the accuracy and stability of the docking structure between the two.

In this embodiment, the second shielding member includes a first shielding plate 507 and a second shielding plate 507', which are respectively arranged outside the two terminal plates 504 to shield the outer side. The two sides of the conductive support frame 506 pass through the two terminal plates 504 and are connected to the first shielding plate 507 and the second shielding plate 507' on both sides to achieve common conduction and grounding.

In the illustrated embodiment, a plurality of third card slots 5071 are provided on the first shielding plate 507 and the second shielding plate 507', and the third card slots 5071 may be through holes or blind holes. A plurality of protruding third card heads 5061 are provided on the edges of both sides of the conductive support frame 506, and both sides of the conductive support frame 506 respectively pass through the sides of the two terminal boards, and the third card heads 5061 on both sides are respectively clamped in the third card slots 5071 of the first shielding plate 507 and the second shielding plate 507'. As an alternative, an elongated slit may be provided on the first shielding plate 507 and the second shielding plate 507' to replace the third card slots 5071. Accordingly, the conductive support frame 506 no longer needs to be provided with a plurality of third card heads 5061 on both sides, but the edges on both sides thereof are inserted into the slit. After the conductive support frame 506 passes through the two terminal plates 504 and is connected to the first shielding plate 507 and the second shielding plate 507', the differential signal pair is enclosed in the space surrounded by the two adjacent metal sheets in the conductive support frame 506 and the first shielding plate 507 and the second shielding plate 507', and both sides and the top and bottom are well shielded, which can effectively reduce or avoid signal interference.

As shown in FIG11 , a first bending portion 5072 is provided on one side edge of the first shielding plate 507, and a second bending portion 5073 is provided on one side edge of the second shielding plate 507′. The first bending portion 5072 and the second bending portion 5073 are opposite to each other and can be connected through a first clamping head 5074 and a first clamping hole 5075 that are separately provided. For example, as shown in FIG14 , a plurality of first clamping heads 5074 are provided on the first bending portion 5072, and a plurality of first clamping holes 5075 are provided on the second bending portion 5073. When connected, the first bending portion 5072 and the second bending portion 5073 overlap, and the first clamping head 5074 is clamped into the first clamping hole 5075. Similarly, the first clamping head 5074 can also be provided on the second bending portion 5073, and the first clamping hole 5075 can be provided on the first bending portion 5072. After the first bending portion 5072 and the second bending portion 5073 are joined together, the outermost signal terminal 505 is wrapped therein to play a shielding role.

As shown in Figs. 10 and 12, the two terminal boards 504 of the terminal module 5 are respectively provided with first buckle grooves 5044, which are arranged along the outermost signal terminals 505. After the first shielding plate 507 and the second shielding plate 507' cover the corresponding terminal boards 504 from both sides, the first bending portion 5072 and the second bending portion 5073 can respectively pass through the corresponding first buckle grooves 5044, so that the first shielding plate 507 and the second shielding plate 507' and the terminal board 504 form a stable connection structure, and the first bending portion 5072 and the second bending portion 5073 pass through the terminal board 504 to surround the signal terminals 505 inside thereof to form a shield.

As shown in Figs. 13 and 14, a plurality of first grounding contacts 5077 are provided at the lower part of the first shielding plate 507, and a plurality of second grounding contacts 5077' are provided at the lower part of the second shielding plate 507'. The positions of the first grounding contacts 5077 and the second grounding contacts 5077' should be able to surround the signal terminal contacts 5051 of each differential signal pair respectively, so as to form a shielding and anti-interference for the signal terminal contacts 5051. The root of the second grounding contact 5077' is provided with a first elastic claw 5078 that can be elastically deformed, and the form can be a two-finger shape as shown in the figure, or other shapes that can achieve the effect of clamping. The root of the first grounding contact 5077 is provided with a first accommodating groove 5079 that is matched and connected with the first elastic claw 5078, so as to strengthen the connection structure of the first shielding plate 507 and the second shielding plate 507', and realize the common conduction and grounding of the plurality of first grounding contacts 5077 and the second grounding contacts 5077' at the contact part, so as to enhance the shielding effect.

Furthermore, the two sides of the lower end of the conductive support frame 506 may also be provided with elastically deformable second claws 5062, which are similar in shape to the first claws 5078. The first grounding contact 5077 and the second grounding contact 5077' are provided with second receiving grooves 5079' that are matched and connected with the second claws 5062. Specifically, the first receiving grooves 5079 and the first claws 5078 may be provided on the first grounding contact and the second grounding contact located on both sides of the first shielding plate 507 and the second shielding plate 507', respectively. The second receiving grooves 5079' may be provided at the roots of the first grounding contact and the second grounding contact located in the middle of the first shielding plate 507 and the second shielding plate 507'.

As a reinforcement of the connection structure, as shown in FIG10 , positioning holes 5076 are provided on the first shielding plate 507 and the second shielding plate 507′, and positioning columns 5045 that cooperate with the positioning holes on the first shielding plate and the second shielding plate are respectively provided on the two terminal plates 504 of the terminal module 5.

15-19 show another embodiment of the shielding structure, in which a second buckle groove 5046 extending along the signal terminal line is provided on one side of each signal terminal 505 on the terminal board 504. That is, among the multiple signal terminals in the terminal board, a second buckle groove 5046 is provided between two adjacent signal terminals and on the outside of the outermost signal terminal. A shielding frame 508 is provided on the outside of each of the two terminal boards 504 of the terminal module 5. The main body 5081 of the shielding frame 508 covers the outside of the signal terminal 505 in the terminal board, forming a second shielding member for outer shielding.

The main body 5081 is provided with a plurality of transverse bending portions 5082 that are bent to one side. The transverse bending portions 5082 extend and are inserted into the corresponding second buckle grooves 5046. On one hand, they play a role of connection and fixing, and on the other hand, they form a shield between the signal terminals. The terminal module 5 is also provided with a conductive buckle frame 509. The frame body 5091 of the conductive buckle frame 509 covers the side of one of the terminal boards. One side of the frame body 5091 is provided with a plurality of transversely extending buckle portions 5092. The plurality of buckle portions 5092 are respectively inserted into the corresponding second buckle grooves 5046 on the terminal board. The buckle portions 5092 are in contact with the transverse bending portions 5082 of the shielding frame 508 that are also inserted into the second buckle grooves 5046 to form a first shielding member for shielding between differential signal pairs.

As shown in Figs. 16-18, the buckle part 5092 is provided with a plurality of second ribs 5093 which are pressed against the transverse bending part 5082. The second ribs 5093 extend along the extension direction of the buckle part 5092, that is, they are arranged along the depth direction of the second buckle groove 5046. The outer end of the second rib 5093 can also be provided with an inclined surface to guide it into the second buckle groove 5046, so that the buckle part 5092 is inserted into the second buckle groove 5046 in the form of interference fit, thereby enhancing the tightness of the buckle part 5092 in contact with the shielding frame 508 and ensuring a good and reliable grounding effect.

As shown in Figure 19, the transverse bending portion 5082 on the shielding frame 508 can be formed by stamping and slitting the metal plate of the shielding frame 508 body and then bending it. Correspondingly, a hollow opening 5083 is formed in the main body 5081 of the shielding frame 508, and the hollow opening 5083 can allow the buckling portion 5092 of the conductive buckle frame 509 to pass through.

As shown in Figs. 18-20, the contact end of the terminal module 5 can be provided with a terminal grounding frame 510 to connect the shielding contacts of the shielding assembly, such as the third grounding contact 5084 of the shielding frame 508, to each other for mutual conduction. Two shielding frames 508 are provided on both sides of the terminal grounding frame 510, and the multiple shielding contacts 503 at the lower end of the shielding frame 508 are connected through the terminal grounding frame 510.

As shown in Figure 20, the terminal grounding frame 510 includes two relatively arranged connecting plates 5101, and the two connecting plates 5101 are connected by multiple connecting strips 5102 to form a hollow frame structure; the signal terminal contacts of the signal terminal 505 in the terminal module 5 pass through the hollow frame without contacting it; the multiple third grounding contacts 5084 of the two shielding frames 508 are respectively connected to the terminal grounding frame 510 from both sides, thereby realizing the common conduction and grounding of the shielding frame 508 and its multiple third grounding contacts 5084.

Furthermore, the portion where the lower end of the shield frame 508 is connected to the third grounding contact 5084 thereof has a bent transverse upper clamping portion 5085, the end of which is a vertically obliquely downward extending portion 5086, and the third grounding contact 5084 is connected to the inner side surface of the lower portion of the extending portion 5086. When connected, the upper clamping portion 5085 is clamped to the upper edge of the connecting plate 5101, and the extending portion 5086 wraps and covers the outer side surface of the connecting plate 5101.

A connecting piece 5103 is provided on the connecting strip 5102 between the connecting plates 5101 on both sides of the terminal grounding frame 510, and third spring claws 5104 are respectively provided on both sides of the connecting piece 5103, and the third spring claws 5104 on both sides are respectively connected to the parts of the third grounding contacts 5084 at the lower ends of the two shielding frames 508 extending into the terminal grounding frame 510. In the illustrated embodiment, a third receiving groove 5087 is provided on the third grounding contact 5084, and the third spring claw 5104 can be matched and snapped into the third receiving groove 5087. The structural components such as the connecting plate 5101, the connecting strip 5102, and the connecting piece 5103 of the terminal grounding frame 510 can be an integrated structure formed by bending a metal plate after integral stamping, which is easy to process and avoids the impact on grounding and shielding effects caused by multi-component multi-level contact.

The third grounding contact 5084 is a sheet-shaped contact sheet perpendicular to the plate surface of the main body of the shield frame 508. The sheet-shaped third grounding contact 5084 extends laterally into the terminal grounding frame 510. A vertically arranged slot 5105 can be provided at a position corresponding to the third grounding contact 5084 on the connecting plate 5101. The upper end of the slot 5105 is sealed, and the lower end extends to the bottom edge of the connecting plate 5101 to form an opening. The third grounding contact 5084 is inserted into the terminal grounding frame 510 from the bottom of the connecting plate 5101 through the slot 5105 and connected to the third spring claw 5104, and cooperates with the upper clamping portion 5085 crimped on the upper side to form a clamping and fixing structure, and ensures the stable connection of various components.

The outer side of the connection plate 5101 of the terminal grounding frame 510 is provided with a jumper 5106 connected to the terminal grounding frame of the adjacent terminal module, which can strengthen the common conductive grounding of the shielding components in multiple terminal modules.

FIG2-4 shows the connection and grounding structure between the terminal module 5 and the socket housing. A conductor frame 7 is provided between the socket housing 6 and the terminal module 5. The contact end 501 of the terminal module 5 is inserted into the conductor frame 7 and fixed in the socket housing 6. As shown in FIG2, the conductor frame 7 has multiple rows of sockets 701 for inserting each group of contacts on each terminal module 5. The number and position of the sockets 701 are consistent with the position and number of the slots on the socket housing 6. A shielding net 8 is provided on the side of the conductor frame 7 facing the terminal module 5. The shielding net 8 has windows 801 matching each socket 701 on the conductor frame 7. The conductor frame 7 is conductive plastic or conductive plastic, and the shielding net 8 is a metal part fixed on the conductor frame 7. The contact end of the terminal module 5 is inserted into the conductor frame 7 and the socket housing 6 in sequence through the window 801 of the shielding net 8. After insertion, the shielding frame 8 is kept at the root position of the contact end of the terminal module 5, forming a shielding layer covering the entire connector plug-in section in the horizontal direction.

As shown in Figs. 2-4, the shielding contacts 503 of all terminal modules 5 inserted into the socket housing 6 are in contact with the shielding net 8, and the shielding components of each terminal module 5 are connected and grounded through the shielding net 8. As shown in Figs. 3 and 4, each window 801 of the shielding net 8 is provided with a first contact 802 protruding toward the center of the window, and thereby contacts the shielding contact 503 of the inserted terminal module 5. For example, a spring is provided, and the spring is squeezed and deformed by the shielding contact 503 when the terminal module 5 is inserted, and an elastic pressure is applied to the shielding contact. The first contact 802 in the form of a spring can be provided only at one end of the side of the window 501, or springs can be provided on both opposite sides of each window 801. The spring contacts the side wall portion 5031 of the inserted shielding contact 503.

As shown in FIG3 , a first rib 702 is provided on the inner side of the socket 701 of the conductor frame 7. The protruding height of the first rib 702 enables it to abut against the side wall of the plug shielding sheet 201 surrounding the differential signal contacts in the plug 2, thereby achieving common grounding of the plug shielding assembly and the socket shielding assembly and improving the shielding effect.

As shown in Figures 5-9, the bottom of each slot 601 is provided with two symmetrical signal terminal contact slots 6013 separated by a differential signal terminal partition 6011. The two signal terminal contact slots 6013 are respectively used to accommodate the signal terminal contacts 5051 of the two signal terminals 505 that constitute the differential signal pair in the terminal module 5.

As shown in FIG6 , the signal terminal contacts 5051 of the two signal terminals 505 of the differential signal pair are inserted into the corresponding signal terminal contact slots 6013 and are defined by them. Each signal terminal contact 5051 has two contact inserts. A plug-in hole is provided at the bottom of the signal terminal contact slot 6013 corresponding to the area between the two contact inserts in the signal terminal contact 5051 as shown in FIG8 , and a signal contact partition 6014 is provided on the side wall of the signal terminal contact slot 6013 corresponding to the plug-in hole and extending in the depth direction thereof for separating the two contact inserts in the signal terminal contact 5051.

The bottom of the slot 601 is provided with an insertion slot for inserting the shielding contact of the terminal module 5 and the plug shielding sheet in the plug at the same time around the two signal terminal contact slots 6013, and the insertion slot is separated from the signal terminal contact slots 6013 by a surrounding plate. The insertion slot includes a shielding contact front slot 6016 extending along the arrangement direction of the two signal terminal contact slots 6013, a shielding contact side slot 6017 arranged on the side of one of the signal terminal contact slots 6013 and connected to one end of the shielding contact front slot 6016, and a shielding sheet side slot arranged on the side of the other signal terminal contact slot 6013 and connected to the other end of the shielding contact front slot 6016. The shielding contact front slot 6016 and the shielding contact side slots 6017 at both ends form a C-shaped through slot. The shape of the entire C-shaped through slot matches the shape of the plug shielding sheet 201 surrounding the differential signal contacts in the plug, and can be inserted into the plug shielding sheet 201. The shielding contact front slot 6016 and the shielding contact side slot 6017 can also be used for inserting shielding contacts in two directions in the terminal module 5 respectively.

For example, the terminal module 5 has two shielding plates, namely the first shielding plate and the second shielding plate, and the shielding contact at the lower end of each shielding plate has a front shielding claw, a side shielding claw and a rear shielding claw. The shielding contact front slot 6016 and the shielding contact side slot 6017 correspond to the front shielding claw and the side shielding claw at the lower end of the shielding plate, respectively. The shielding contact and the plug shielding sheet 201 inserted into the slot at the same time are pressed against each other under the extrusion of the slot wall to achieve a synchronous grounding shielding effect.

Among the multiple slots 601 on the socket housing 6, a slot at the end of each row of slots 601 is provided with a shielding contact rear slot 6018 opposite to the shielding contact front slot 6016 at the other side of the signal terminal contact slot 6013. The shielding contact rear slot 6018 can be simultaneously inserted with the corresponding terminal module shielding contact (such as the rear shielding claw) and the plate-shaped shielding sheet in the plug.

A shielding contact partition 6015 is provided on one inner side wall of the shielding contact front slot 6016 and the shielding contact rear slot 6018, and a gap is provided between the shielding contact partition 6015 and the other inner side wall of the shielding contact front slot 6016 or the shielding contact rear slot 6018. The shielding contact partition 6015 is provided with a guiding slope at one end facing the bottom of the socket housing 6, and a positioning step surface at the other end. The portion where the front shielding claws at the lower ends of the two shielding plates in the terminal module 5 meet can be kept on the positioning step surface to limit the insertion depth. The plug shielding sheet 201 can be inserted into the insertion slot at the bottom of the slot 601 guided by the guiding slope, and can be squeezed by the shielding contact partition 6015. The first convex rib 702 disposed inside the socket 701 of the conductor frame 7 is opposite to the shielding contact partition 6015, and the plug shielding sheet 201 is squeezed between the shielding contact partition 6015 and the first convex rib 702, so that the plug shielding sheet 201 and the conductor frame 7 are well grounded together. At the same time, the conductor frame 7 is provided with a connecting component (such as the first contact piece 802 of the shielding net 8) that contacts the shielding contact of the terminal module 5, so that the shielding components of the socket and the plug are grounded together as a whole, thereby improving the shielding effect.
