[0022] Please see Figures 1 to 6 The connector 100 in this embodiment of the present invention includes: The two corresponding insulating components 20 are set; Two terminal groups 30 are respectively disposed on the outside of the two insulating members 20. Each terminal group 30 includes multiple signal terminals 31 and multiple ground terminals 32, with one ground terminal 32 and a predetermined number of signal terminals 31 alternately arranged; and Two shorting pieces 10 are respectively provided on the inner side of the two insulating members 20. The two shorting pieces 10 are arranged back to back and their inner sides are connected. Multiple shorting structures 11 protruding towards the corresponding insulating member 20 are provided on the shorting pieces 10. The multiple shorting structures 11 are electrically connected to multiple grounding terminals 32. The two shorting structures 11 on the two shorting pieces 10 form a space 12 between the corresponding two shorting structures 11.

[0023] In the connector 100 of this embodiment, two terminal groups 30 are respectively disposed on the outside of two insulating members 20 and located on both sides of the connector 100. Two shorting tabs 10 are disposed between the two terminal groups 30. Multiple shorting structures 11 protruding towards the corresponding insulating members 20 are provided on the shorting tabs 10. The multiple shorting structures 11 are electrically connected to multiple grounding terminals 32 to realize the grounding shorting of the terminal groups 30. Moreover, the two corresponding shorting structures 11 on the two shorting tabs 10 form a gap space 12, which increases the electrical distance between the grounding terminals 32 on both sides and can effectively improve the anti-crosstalk capability between the two terminal groups 30. In this embodiment, the insulating member 20 can be an integrally injection-molded plastic part. On the one hand, the top of the insulating member 20 can be provided with a plurality of mounting holes (not shown) spaced apart along its length direction. On the side of the insulating member 20 away from the shorting piece 10, a plurality of mounting grooves (not shown) corresponding to the plurality of mounting holes and extending along the width direction of the insulating member 20 can be provided. The terminal group 30 passes through the plurality of mounting holes and is embedded in the plurality of mounting grooves. The shape of the mounting groove corresponding to the signal terminal 31 is adapted to the shape of the signal terminal 31, and the shape of the mounting groove corresponding to the ground terminal 32 is adapted to the shape of the ground terminal 32, so as to ensure the stable setting of the terminal group 30 on the insulating member 20.

[0024] A limiting part can be provided below the mounting hole corresponding to the grounding terminal 32, and a limiting hole 3 is provided on the grounding terminal 32. The limiting part is embedded in the limiting hole 3. In this way, the insulating part 20 can be used to stably install the grounding terminal 32, so that multiple grounding terminals 32 are insulated and isolated from each other, avoiding the situation where multiple grounding terminals 32 shake or fall off and disconnect from the short-circuit structure 11, and ensuring the stability and safety of the connector 100 when connecting and disconnecting from the external interface; On the other hand, the two insulating members 20 are arranged at intervals relative to each other, and the space between them is used to install two shorting pieces 10, that is, the shorting pieces 10 are located inside the connector 100, making the structure of the connector 100 more compact.

[0025] In this embodiment, the connector 100 can be divided into two halves: a first half consisting of a terminal group 30, an insulating element 20, and a shorting piece 10, such as the first terminal group 30, the first insulating element 20, and the first shorting piece 10; and a second half consisting of a second terminal group 30, another insulating element 20, and another shorting piece 10, such as the second terminal group 30, the second insulating element 20, and the second shorting piece 10. During assembly, the two halves can be assembled into two independent structures according to the above components, and then the two halves can be installed accordingly to obtain the connector 100.

[0026] Specifically, multiple terminals in the terminal group 30 are evenly arranged on two insulating members 20, the number of terminal groups 30 on the two insulating members 20 is the same and they are symmetrically arranged, and multiple terminals on a single insulating member 20 are evenly spaced to form a regular connector 100 structure.

[0027] Multiple grounding terminals 32 provide multiple grounding paths, so that even if one path fails, the others can still function normally, improving the stability and reliability of the connector 100. Furthermore, multiple grounding terminals 32 can disperse current, reduce electromagnetic interference and noise, ensure clean signal transmission, and contribute to the high precision and high-speed transmission of the connector 100.

[0028] One grounding terminal 32 and a set number of signal terminals 31 are alternately arranged to meet the short-circuit requirements and signal transmission requirements of the connector 100. The set number of signal terminals 31 is specifically set according to the signal transmission requirements of the connector 100, such as 1, 2, 3, etc.

[0029] exist Figures 1 to 3 In the embodiment shown, the number is set to 2, that is, 1 ground terminal 32 and 2 signal terminals 31 are alternately arranged on the insulating member 20 in the pattern of 1 ground terminal 32-2 signal terminals 31-1 ground terminal 32-2 signal terminals 31-1 ground terminal 32... and both ends of the connector 100 are ground terminals 32. These two ground terminals 32 have extensions that extend outward for grounding connection, which facilitates direct connection with external interfaces to achieve grounding.

[0030] In this embodiment, the shorting piece 10 is integrally formed, such as by integral sintering or integral stamping, which simplifies the manufacturing process and improves the structural strength of the shorting piece 10. Multiple shorting structures 11 are disposed on the outer surface of the shorting piece 10 facing the insulating member 20, facilitating connection with multiple grounding terminals 32 disposed on the insulating member 20.

[0031] The interval space 12 is an approximately hexagonal space enclosed by the inner spaces of the two shorting structures 11, so that the two corresponding shorting structures 11 on the two shorting pieces 10 are spaced a certain distance apart, so as to avoid mutual interference caused by the distance being too close.

[0032] Please see Figure 1 , Figure 4 and Figure 5 Furthermore, the shorting piece 10 also includes a connecting portion 13 that connects adjacent shorting structures 11, with the inner sides of the corresponding two connecting portions 13 on the two shorting pieces 10 connected together.

[0033] Specifically, the connecting part 13 is a long strip-shaped structure extending along the width direction of the shorting piece 10, so as to connect the adjacent shorting structure 11 on the shorting piece 10 as a whole. The shorting structure 11 protrudes outward toward the insulating member 20, while the shorting part 111 protrudes inward toward the insulating member 20, so as to correspond and fit with the shorting part 111 on another shorting piece 10, thereby realizing the connection between the two shorting pieces 10.

[0034] Please continue reading. Figure 1 , Figure 4 and Figure 5 Furthermore, the top and bottom ends of the connecting part 13 are exposed from the top and bottom of the insulating member 20, respectively, and the top and / or bottom ends of the corresponding two connecting parts 13 on the two shorting pieces 10 are welded and fixed.

[0035] In this embodiment, two shorting pieces 10 are provided correspondingly, and the connecting parts 13 on each are also provided correspondingly. The structural stability of the connector 100 is ensured by welding and fixing the top and / or bottom ends of the corresponding two connecting parts 13.

[0036] Preferably, the top and bottom of the two connectors 100 are welded and fixed, making the overall structure of the connectors 100 more stable.

[0037] Please see Figure 2 , Figure 3 and Figure 6 Furthermore, the top of the insulating member 20 is provided with a plurality of mounting portions 21 spaced apart, a predetermined number of signal terminals 31 passing through the mounting portions 21 and extending along the width direction of the insulating member 20, and grounding terminals 32 located between adjacent mounting portions 21.

[0038] In this embodiment, the mounting portion 21 defines the position of the signal terminal 31, making the signal terminal 31 more stable on the insulating member 20 and maintaining an insulating gap between the signal terminals 31. The adjacent mounting portion 21 defines the position of the ground terminal 32, making the positional relationship between the ground terminal 32 and the signal terminal 31 clearer and maintaining an insulating gap. Moreover, the shape of the mounting portion 21 is adapted to the shape of the space between the adjacent shorting structures 11, making the top space of the connector 100 more compact and tight.

[0039] Please see Figures 3 to 5 Furthermore, the shorting structure 11 includes a plurality of shorting portions 111 spaced apart along the width direction of the shorting piece 10. The shorting portions 111 protrude toward the insulating member 20, and each of the plurality of shorting portions 111 is electrically connected to a corresponding grounding terminal 32.

[0040] In this embodiment, the shorting structure 11 is not a single piece, but is formed by combining multiple shorting portions 111. Each shorting portion 111 is a generally arc-shaped protrusion on the shorting piece 10. Each shorting portion 111 of the shorting structure 11 contacts the grounding terminal 32 for electrical connection, ensuring the grounding connection effect. Moreover, each shorting portion 111 is spaced apart by a gap hole, which can be used to cooperate with the insulating member 20, making the structure between the insulating member 20 and the shorting piece 10 more stable.

[0041] Please continue reading. Figures 3 to 5 Furthermore, the uppermost shorting portion 111 protrudes from the top of the insulating member 20, and the lowermost shorting portion 111 protrudes from the bottom of the insulating member 20. The uppermost and lowermost shorting portions 111 protruding from the insulating member 20 facilitate the determination of the alignment contact electrical connection between the grounding terminal 32 and the shorting structure 11.

[0042] The number of shorting sections 111 can be set according to actual needs. Figure 5In the embodiment shown, there are four shorting portions 111. From top to bottom, the first shorting portion 111 and the fourth shorting portion 111 are exposed above and below the insulating member 20, respectively, and the second shorting portion 111 and the third shorting portion 111 are located within the coverage area of ​​the insulating member 20.

[0043] Furthermore, the shorting portion 111 is formed by protruding from the inside to the outside of the shorting piece 10. The shorting piece 10 can be directly integrally sintered or stamped to form the shorting portion 111 without secondary processing, making the structure of the shorting portion 111 and the shorting piece 10 more integrated and stable.

[0044] Please see Figures 3 to 6 Furthermore, the first groove 22 and the second groove 23 are spaced apart on the inner side of the insulating member 20 along its own width direction, and the two short-connection portions 111 located within the coverage area of ​​the insulating member 20 are respectively fitted into the first groove 22 and the second groove 23.

[0045] The grounding terminal 32 is exposed in the first groove 22 and the second groove 23 and is in contact with the two shorting parts 111. The first groove 22 is higher than the second groove 23. The size of the first groove 22 and the second groove 23 is adapted to the size of the two shorting parts 111. If the size is similar or equal, it ensures that the two shorting parts 111 can fully contact and connect with the grounding terminal 32. The two shorting parts 111 are the second shorting part 111 and the third shorting part 111 mentioned above.

[0046] Please see Figures 3 to 6 Furthermore, the insulating member 20 is provided with a plurality of mating parts 24 distributed at intervals along the length direction of the insulating member 20 on the side facing the shorting piece 10. The mating parts 24 are embedded between two shorting parts 111 that are adjacent in the width direction of the insulating member 20 and are located within the coverage area of ​​the insulating member 20.

[0047] Specifically, multiple mating parts 24 are spaced apart along the length of the insulating member 20 to correspond to multiple shorting structures 11, making the connection between the insulating member 20 and the shorting piece 10 tighter and the structure more stable, thereby improving the structural stability and compactness of the connector 100.

[0048] Please see Figure 2 and Figure 6 Furthermore, the bottom of the insulating component 20 is provided with a first positioning part 25 and a first positioning hole 26 spaced apart, and the top two ends are respectively provided with a second positioning part 27 and a second positioning hole 28. The first positioning part 25, the first positioning hole 26, the second positioning part 27 and the second positioning hole 28 of one insulating member 20 are respectively fitted and engaged with the first positioning hole 26, the first positioning part 25, the second positioning hole 28 and the second positioning part 27 of another insulating member 20.

[0049] Specifically, the two insulating parts 20 have basically the same structure. The first positioning part 25 can be a positioning post structure with strip-shaped protrusions around it to increase the fitting stability. The first positioning hole 26 is a hole-shaped structure that matches the shape of the cross-section of the first positioning part 25. When the first positioning part 25 and the first positioning hole 26 of one insulating part 20 are fitted and engaged with the first positioning hole 26 and the first positioning part 25 of the other insulating part 20, elastic deformation occurs and the two insulating parts 20 are locked together. The bottoms of the two insulating parts 20 can be directly and stably fixed together.

[0050] The second positioning part 27 can be a block-shaped protrusion, and the second positioning hole 28 is a hole-shaped structure that matches the shape of the cross-section of the second positioning part 27. When the second positioning part 27 and the second positioning hole 28 of one insulating member 20 are fitted and engaged with the second positioning hole 28 and the second positioning part 27 of another insulating member 20, elastic deformation occurs and the two insulating members 20 are locked together. This can fix the top ends of the two insulating members 20 together, thereby simply and effectively fixing the connector 100 in four directions, ensuring structural stability, and also facilitating the disassembly and assembly of the connector 100.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
