[0066] Example 1

[0067] See also Figure 1-Figure 4 A board-mounted diagnostic connector includes an insulating base 100, a support platform 200, and a plurality of metal pins 300. The insulating base 100 has a front interface 110 and a rear interface 120 arranged back to back. The plurality of metal pins 300 are arranged in the insulating base 100, the first part 310 of the metal pin 300 extends from the front interface 110, and the second part 320 of the metal pin 300 extends from the rear interface 120. The support platform 200 is fixedly arranged on the rear interface 120 of the insulating base 100 and is located on both sides of the second part 320 of the plurality of metal pins 300. The support platform 200 is mainly used to support a PCB board 400 that matches the board-mounted diagnostic connector and to position and connect with the PCB board 400.

[0068] In this embodiment, the structure of insulating base 100 is a standard structure known to those skilled in the art. Specifically, insulating base 100 has a socket 101 within it. The bottom surface of socket 101 serves as the front interface 110 of insulating base 100, which is a connector interface compliant with the ISO 16989 standard. The surface of insulating base 100 has an integrally formed rib structure 130. This rib structure 130 primarily serves to prevent a plug-in from being connected to the insulating base 100 of the board-mounted diagnostic connector (by partially encasing the plug-in on insulating base 100).

[0069] In this embodiment, the insulating base 100 is an injection-molded part, and the plurality of metal antennae are connected to the insulating base 100 by injection molding. The integrated combination makes the board-mounted diagnostic connector completely waterproof.

[0070] In this embodiment, please refer to Figure 5 and Figure 6, multiple metal pins 300 are combined to form two pin groups, the two pin groups are arranged at intervals along the first direction, each pin group includes at least two metal pins 300, and all the metal pins 300 contained in each pin group are arranged at intervals along the second direction, and, on the side of the front end interface 110, the multiple metal pins 300 are arranged symmetrically in two rows, and on the side of the rear end interface, the multiple metal pins 300 are arranged staggered in two rows, that is, the second parts 320 of the multiple metal pins 300 contained in the two pin groups are staggered along the second direction, wherein the first direction and the second direction are perpendicularly intersected. It can be understood that the first part 310 and the second part 320 are staggered and extended along their own length directions.

[0071] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 6 The second part 320 of the metal pin 300 is a bent structure, that is, the second part 320 includes a transition connection part 321 and a contact connection part 322 arranged in sequence, the transition connection part 321 is fixedly connected to the first part 310, and the end of the contact connection part 322 away from the transition connection part 321 is a contact end for electrically connecting to the PCB board 400, the contact connection part 322 is arranged at an angle to the transition connection part 321 to form a bent structure, and the contact connection parts 322 of the second parts 320 of the two pin groups extend in the same direction. More specifically, the transition connection part 321 is perpendicular to the rear end interface 120, and the contact connection part 322 is perpendicular to the transition connection part 321. The contact ends of all the metal pins 300 contained in the two pin groups are located in the same plane, wherein the contact ends of all the metal pins 300 contained in the same pin group are located on the same straight line, and the contact ends of the two pin groups are respectively located on two parallel straight lines. As a typical solution, the contact connection portions 322 of the two pin groups may be spaced apart in a direction away from the rear end interface 120 .

[0072] It should be noted that by staggering the arrangement of the plurality of metal pins 300 on one side of the rear end interface, combined with the bending structure of the second portion 320 , more different arrangement methods can be achieved within a limited space.

[0073] In this embodiment, the support platform 200 includes two support portions 210, which are spaced apart along the second direction on either side of the two pin groups. Furthermore, in the first direction, the contact ends of the metal pins 300 are positioned below the bottom surface of the support platform 200. This means that when the support platform 200 is positioned and connected to the PCB 400, the support portions 210 do not affect the electrical connection between the contact terminals of the metal pins 300 and the PCB 400.

[0074] In this embodiment, the support platform 200 is further provided with a positioning column 220, and the positioning column 220 can be set on the top table of the support portion. The positioning column 220 is used to match the positioning hole on the PCB board 400 to achieve a structural positioning connection with the PCB board 400, so that the multiple metal pins 300 on the board-mounted diagnostic connector can accurately correspond to the contact terminals on the PCB board 400. The connection state between the board-mounted diagnostic connector and the PCB board 400 is as follows: Figure 7 In this embodiment, the support platform 200 and the insulating base 100 are integrally provided. Specifically, the support platform 200 and the insulating base 100 are an integrally formed injection molded body.

[0076] Please also refer to Figure 8 and Figure 9 The structure of a board-mounted diagnostic connector in this embodiment is basically the same as that in Example 1. The common parts between the two will not be repeated here. The main difference between the two is that the two groups of metal pins 300 in this embodiment are arranged symmetrically in two rows on one side of the front interface 110 and the rear interface 120, and the contact connection parts 322 of the second parts 320 of the two groups of metal pins 300 extend in opposite directions. Each pin group is used to electrically connect to a PCB board 400.

[0077] Example 3

[0078] Please also refer to Figure 10 The structure of a board-mounted diagnostic connector in this embodiment is basically the same as that in Example 1. The common parts between the two will not be repeated here. The main difference between the two is that the two groups of metal pins 300 in this embodiment are arranged symmetrically in two rows on the front interface 110 and the rear interface 120. In addition, the second portion 320 of the metal pins 300 in this embodiment is a non-bent flat plate structure. A clearance gap is formed between the two pin groups to avoid the PCB board 400. The two pin groups are electrically connected to the same PCB board 400.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly.
