[0010] Preferably, after the cable connector inserts the connecting module into the insulating shell, an insulating tail portion for fixing the connecting module is also injection molded on the rear side of the connecting module and the insulating shell. The insulating tail portion wraps around the cable, and the extended clamp of the reinforcing member is clamped on the insulating tail portion.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

[0044] Example 1: Please see Figure 1 , Figure 2 As shown, the high-speed transmission device of this application uses Figure 1 The X direction is the front in the vertical direction, the Y direction is the horizontal direction, and the Z direction is the top in the vertical direction.

[0045] The high-speed transmission device of this application includes a housing A on which a printed circuit board 13 is fixed, and a cable connector assembly B that mates with the printed circuit board 13 inside the housing A. The cable connector assembly B is an assembly that combines and fixes at least two cable connectors S1 and S2 into a single unit.

[0046] The housing A includes a bottom shell 11, a cover plate 12 fixed to the bottom shell 11, and rivets 14 fixed or machined onto the bottom shell 11. The bottom surface of the bottom shell 11 is a flat plate structure. The cover plate 12 includes a cover plate body 121 and two side portions 122 formed by bending downward from both sides of the cover plate body 121. The cover plate 12 is supported and fixed to the bottom shell 11 by the bottom of the side portions 122. The side portions 122 have a supporting structure 15 facing between the two side portions 122. The printed circuit board 13 is fixed to the supporting structure 15, so that the bottom surface of the printed circuit board 13 is kept at a certain distance from the surface of the bottom shell 11, that is, the printed circuit board 13 is fixed to the side portions 122.

[0047] The front end of the printed circuit board 13 is processed into several independently protruding plug-in plates 131, each plug-in plate 131 having corresponding gold fingers for contact. The number of plug-in plates 131 is set or changed according to the needs and standards of the device. When applied to MCIO connectors, the plug-in plates 131 on the printed circuit board 13 correspond to the plug-in plates of wire-end connectors in the prior art, that is, the original wire-end connector is integrated onto the printed circuit board 13, converting the original board-end connector soldered onto the board into a wire-end connector. In this way, the cost of one connector can be reduced in practical applications. However, after processing the end of the printed circuit board 13 into plug-in plates 131, a transmission device needs to insert multiple wire-end connectors. When inserting them individually, it is not convenient to fix them as a whole, and the overall connectivity will weaken the strength of the plug-in plates 131. Under external force, a few plug-in plates 131 may be easily damaged when subjected to force alone.

[0048] Please continue reading. Figures 3 to 17 As shown, the cable connector assembly B of this application includes at least two cable connectors S1 and S2. The two cable connectors S1 and S2 are then combined and fixed together to form a single unit.

[0049] Key references Figure 3 , Figure 4 As shown, the cable connector assembly B includes a first cable connector S1, a second cable connector S2, a reinforcing member 60 that pre-laps the first cable connector S1 and the second cable connector S2 together, a connecting member 50 that secures the reinforcing member 60 to the first cable connector S1 and the second cable connector S2 as a whole, and a bolt assembly 70 that locks the cable connector assembly B onto the housing A.

[0050] The first cable connector S1 and the second cable connector S2 have basically the same structure, but there is a difference in the number of interface standards. Hereinafter, the first cable connector S1 and the second cable connector S2 will be collectively referred to as cable connectors.

[0051] The cable connector includes several sets of connection modules 20, an insulating shell 30 for inserting the connection modules 20, and an insulating tail 40 for fixing the connection modules 20 inside the insulating shell 30.

[0052] Please refer to this carefully. Figures 4 to 10 , Figure 17 As shown, each group of connection modules 20 includes a first connection module 201 and a second connection module 202 arranged opposite to each other. The first connection module 201 and the second connection module 202 make electrical contact with the plug-in board 131 of the printed circuit board 13 by clamping. Each connection module 20 includes a plurality of conductive terminals 22, an insulating strip 21 that holds the plurality of conductive terminals 22 together, a cable 25 that is soldered to the conductive terminals 22 through wire cores 251, a shielding connection strip 23 that is fixed to the insulating strip 21 and conducts the predetermined conductive terminals 22 in a regular manner, and a wrapping piece 24 that forms and covers the solder joint between the conductive terminals 22 and the wire cores 251.

[0053] Each group of conductive terminals 22 includes a plurality of conductive terminals, and each group of conductive terminals 22 includes a plurality of pairs of signal terminals 221 and ground terminals 222 located between and outside the pairs of signal terminals 221. Each pair of signal terminals 221 forms a differential pair, and the width of the ground terminal 222 is greater than the width of the signal terminal 221. Each conductive terminal 22 includes an embedded retaining portion 223 formed and fixed within the insulating strip 21, a connecting portion 224 extending rearward from the embedded retaining portion 223 beyond the insulating strip 21, an elastic arm 225 formed by bending obliquely inward from the front end of the embedded retaining portion 223, a pre-compression end portion 227 formed by bending outward from the end of the elastic arm 225, and a contact portion 226 formed at the end of the elastic arm 225. The contact portion 226 and the pre-compression end portion 227 are thinned so that their thickness is less than the thickness of the elastic arm 225.

[0054] The insulating strip 21 is set with a corresponding length according to the number of conductive terminals 22 in each connecting module 20, and the inner surface of the insulating strip 21 is provided with a filling groove 211 with an open rear end. The filling groove 211 is filled during the subsequent injection molding of the package 24 to increase the bonding force between the insulating strip 21 and the package 24. The shielding connecting strip 23 is installed or integrally formed on the insulating strip 21 and integrally connects several grounding terminals 222. The shielding connecting strip 23 includes a connecting body 231 extending laterally and a support portion 232 extending from the front end of the connecting body 231. The connecting body 231 includes several peaks 2312 that are attached to or fixed on the outer surface of the insulating strip 21 and several valleys 2311 that are recessed inward from the peaks 2312. The valleys 2311 are recessed into the interior of the insulating strip 21 and make electrical contact with the corresponding grounding terminal 222. The peak portion 2312 has an opening 2313, which can be positioned or latched by corresponding protrusions on the surface of the insulating strip 21. The inner side of the valley portion 2311 is in direct physical contact with the outer surface of the grounding terminal 222. The support portion 232 includes a plurality of extension strips 2321 extending forward from the peak portion 2312 and a connecting beam 2322 connecting the plurality of extension strips 2321 together at their ends. The length of the connecting beam 2322 can be split as needed, i.e., there can be one or more connecting beams 2322. A cutout 2323 is formed between the valley portion 2311 and the connecting beam 2322 to avoid interference with the corresponding conductive terminal 22. The extension strips 2321 are located outside the signal terminal 221 and can provide a certain shielding performance. The support portion 232 protrudes forward to the front of the insulating strip 21, preferably not exceeding the contact portion 226. To ensure the valley portion 2311 is securely connected to the grounding terminal 222, the valley portion 2311 and the grounding terminal 222 can be spot-welded together. The outer surface of the peak portion 2312 is kept on the same horizontal plane as the outer surface of the insulating strip 21, that is, the peak portion 2312 is embedded at least its thickness into the insulating strip 21.

[0055] Key references Figure 5 , Figure 17As shown, the core 251 of the cable 25 is soldered to the connecting portion 224 corresponding to the conductive terminal 22, and the cable 25 is bent inward from the rear end of the connecting portion 224 and then extended horizontally. Then, the conductive terminal 22 with the soldered cable 25 and the insulating strip are injection molded again to form the wrapping component 24. The wrapping component 24 completely wraps the connection between the core 251 and the connecting portion 224, and at least a portion of the cable 25 is wrapped by the wrapping component 24. The wrapping component 24 is attached to the rear end of the insulating strip 21, and the filling groove 211 is filled by the wrapping component 24. The plastic at the filling area forms an integral structure with the wrapping component 24, making the connection between the insulating strip 21 and the wrapping component 24 more stable and reliable. The filling groove 211 has an irregular shape.

The front end of the insulating shell 30 opens rearward to form a docking cavity 33, and an inclined insertion guide 331 is provided at the front edge of the docking cavity 33. The rear end of the insulating shell 30 opens forward to form two insertion cavities 31, upper and lower, with a partition 32 formed between the two insertion cavities 31. The partition 32 extends rearward beyond the rear end face of the insulating shell 30 between the upper and lower insertion cavities 31. The upper and lower insertion cavities 31 communicate and merge with the docking cavity 33 on the front side. A support cavity 35 is formed on the inner wall surface of the insertion cavity 31, and the support part 232 of the connecting module 20 is inserted into the support cavity 35 for fixation. The mating cavity 33 has forming holes 34 extending through its upper and lower sides. An arc-shaped pre-pressing surface 341 is formed on the inner side of each forming hole 34. The function of the forming holes 34 is to form the pre-pressing surface 341 to facilitate mold demolding. The inner wall of the insertion cavity 31 is further outward than the pre-pressing surface 341, and there is a certain distance between them.

[0057] Key references Figures 1 to 17 As shown below, the assembly method of the cable connectors S1 and S2 of this application will be described in detail: S101.

S103. The wire cores 251 of several cables 25 are soldered to the connecting part 224 at the rear end of the conductive terminal 22, and then injection molded again to form a wrapping part 24 that wraps the connecting part 224 and the wire cores 251; and the connecting module 20 is formed. S104. Provide the insulating shell 30, and insert a plurality of the connecting modules 20 into the insertion cavity 31 from the rear end of the insulating shell 30 respectively; Specifically, when each connecting module 20 is inserted into the insertion cavity 31, the insulating strip 21 is clamped and fixed between the partition 32 and the top wall 301 or the bottom wall 302.

[0058] S105. The assembly of the connecting module 20 and the insulating shell 30 is formed by in-mold injection molding to form the insulating tail 40. The insulating tail portion 40 fills the gap between the cable 25 and the partition 32 and fixes the first connecting module 201 and the second connecting module 202 inside the insertion cavity 31. Thus, the cable connectors S1 and S2 are assembled.

The thread of the threaded section 713 is formed outward from the outer surface of the threaded rod 712, that is, the outer diameter of the threaded section 713 is slightly larger than the outer diameter of the threaded rod 712.

[0065] Please refer to this carefully. Figure 3 , Figure 4 , Figures 15 to 17 As shown, a method for manufacturing the cable connector assembly B of this application will be described, including the following steps: S201. Provide two cable connectors S1 and S2, and first pre-fix the two cable connectors S1 and S2 together by the reinforcing member 60. Specifically, the first reinforcing member 601 overlaps between the two cable connectors S1 and S2. The extended clamping plates 65 on both sides of the upper clamping plate 62 and lower clamping plate 63 respectively clamp the insulating tails 40 of the two cable connectors S1 and S2. The screw hole 64 is located between the two cable connectors S1 and S2. Two pairs of hooks 67 located on both sides of the screw hole 64 pass through the insertion channel 363 at the rear end of the first side wall 303 of the insulating shell 30 and are bent and fixed to the insulating shell 30 of the two cable connectors S1 and S2. Simultaneously, the extended clamping plates 65 of the two second reinforcing members 602 clamp one side of the two cable connectors S1 and S2. Similarly, in specific implementations, the second reinforcing member 602 can also be provided with a pair of hooks 67 for corresponding fixation to the second side wall 304. Meanwhile, the upper clamping plate 62, lower clamping plate 63, and screw hole 64 of the second reinforcing member 602 are located on the side of the cable connectors S1 and S2 and are suspended.

[0066] S202. The two cable connectors S1 and S2, which are pre-fixed by the reinforcing member 60, are once again injection molded to form a connecting member 50 that encloses the reinforcing member 60. Specifically, the connecting member 50 encloses the reinforcing member 60 and the insulating tail 40, and the upper and lower surfaces of the connecting member 50 are respectively on the same horizontal plane as the top wall 301 and bottom wall 302 of the insulating shell 30. The reinforcing member 60 acts as a connecting skeleton to strengthen the connecting member 50 between the two cable connectors S1 and S2. At the same time, the screw holes 52 of the connecting member 50 are formed at the screw holes 64 of the three reinforcing members 60 to facilitate locking the bolt assembly 70.

[0067] S203. Install the bolt assembly 70 into the bolt holes 52, 64; Specifically, the spring 72 is first fitted over the screw 712 of the bolt 71. Then, the bolt 71 is screwed downwards into the screw hole 64 and passes through the screw hole 64. The outer diameter of the screw 712 is smaller than the inner diameter of the screw hole 64, while the outer diameter of the threaded section 713 is larger than the inner diameter of the screw hole 64. The threaded section 713 finally passes through the screw hole 64 and enters the rivet groove 53. In this way, the threaded section 713 is confined below the screw hole 64 and stably positioned on the cable connector assembly B without falling off.

[0068] Thus, the cable connector assembly B is assembled.

[0069] When applied to the high-speed transmission device of this application, the printed circuit board 13 inside the housing A is first fixed, and then the cable connector assembly B is inserted and mated with the plug plate 131 of the printed circuit board 13 from back to front. At this time, the plug plate 131 is inserted into the mating cavities 33 of the multiple cable connectors S1, S2 of the cable connector assembly B, so that the conductive terminals 22 in the mating cavities 33 clamp the plug plate 131 and achieve electrical conduction with the gold fingers on the plug plate 131. Then, the screw 712 of the bolt assembly 70 is screwed into the rivet 14 fixed on the bottom shell 11 and fixed to maintain a stable connection of the cable connector assembly B. The rivet 14 is accommodated in the rivet groove 53 of the connecting member 50.

[0070] In another embodiment, the high-speed transmission device of this application can also be individually connected to the plug-in board 131 inside the housing A using one or more independent cable connectors S1, S2. That is, the high-speed transmission device of this application is not limited to multiple cable connectors S1, S2 combined into a whole to achieve electrical connection.

[0071] The cable connector and high-speed transmission device of this application integrate the traditional wire-end connector with circuit board onto the printed circuit board 13 of the device, and then transform the traditional board-end connector into a cable connector. This solution solves the problem of the traditional device requiring board-end connector and wire-end connector to cooperate to complete high-speed transmission with a single cable connector, which greatly reduces the product cost.

[0072] Meanwhile, the cable connector assembly B of this application combines multiple independent cable connectors S1, S2 into a stable whole by embedding reinforcement 60 and optimizing injection molding process, thereby achieving convenience and stability in connection with printed circuit board 13.

[0073] Example 2: Please continue reading. Figures 18 to 22As shown, the structure and function of the housing A and cable connectors S1 and S2 in Embodiment 2 of this application are the same as those in Embodiment 1, and will not be described again here. The difference lies in the way the cable connector assembly B combines the multiple cable connectors S1 and S2 together.

[0074] In the cable connector assembly B of Embodiment 2, the individual cable connectors S1 and S2 are already processed individual cable connectors S1 and S2 when they are assembled together. That is, in Embodiment 2, the injection-molded connecting member 50 is first individually molded on each cable connector and then the multiple cable connectors S1 and S2 are combined together by the connecting member 80.

[0075] Specifically, in Embodiment 2, the function of the connecting member 50 is no longer limited by its name; in Embodiment 2, the connecting member 50 serves as a wrapping component for the cable connector unit. In this case, the outer lateral side of the connecting member body 51 has the same screw holes 52, and the inner lateral side of the connecting member body 51 has a partial screw hole 52 structure. The upper surface of the connecting member body 51 has several blind holes 54, which are used to position the connecting module 20, the insulating tail 40, or for engaging with the subsequent connecting member 80 during injection molding. The lower surface at both lateral ends of the connecting member body 51 has several fixing grooves 55.

[0076] The connecting member 80 includes a plate portion 81 extending laterally, a plurality of claws 82 extending downward from both ends of the plate portion 81 in the longitudinal direction, and a plurality of screw holes 83 formed through the plate portion 81. Each claw 82 includes a bent portion 821 bent downward from one end of the plate portion 81 in the longitudinal direction, a latching portion 822 bent horizontally inward from the bent portion 821, and a latching hole 823 formed on the latching portion 822. The screw holes 83 are recessed downward to form a surrounding structure, and threads are machined on the inner wall surface of the surrounding structure.

[0077] During assembly, the two cable connectors S1 and S2 are placed side by side on the assembly fixture. The connecting member 80 is attached to the upper surface of the two cable connectors S1 and S2, and the claw 82 extends downward to the lower surface of the coupling member 50 and bends inward to be fixed into the fixing groove 55. The lower surface of the claw 82 is aligned with the bottom surface of the cable connectors S1 and S2. The surrounding structure of the screw hole 83 extends into the screw hole 52 of the coupling member 50, and the threaded section 713 of the screw 712 passes through the surrounding structure and enters the rivet groove 53 by screwing it in.

[0078] Compared to Embodiment 1, this embodiment simplifies the combination of the two cable connectors S1 and S2, but its stability is relatively weaker. Both Embodiment 1 and Embodiment 2 are feasible solutions that can be implemented independently. Furthermore, in Embodiment 2, the connecting member 50 does not need to be molded separately; instead, it can be integrated with the insulating tail portion 40 and injection molded in one step. That is, in Embodiment 2, the relevant structural features of the connecting member 50 can be integrated onto the insulating tail portion 40.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention should be determined by the appended claims.
