The first connector 4 may be made of copper or the like, and the first connector 4 may be directly connected to the electrical contact 21 of the relay 2, thereby achieving electrical connection between the first connector 4 and the relay 2.

[0045] like Figure 4 As shown, the relay 2 can be located below the first connector 4, and there can be multiple relays 2, each of which can correspond to two jacks 41 on the first connector 4. The relay 2 is located below the first connector 4, and the electrical contact 21 can be located on the top side of the relay 2.

[0046] During assembly, the two electrical contacts 21 on the relay 2 can be plugged into the corresponding two sockets 41 . After the assembly is completed, the electrical contacts 21 and the first connector 4 can be electrically connected by welding in the sockets 41 .

[0047] In some embodiments, the housing 1 includes a housing body 11 and a second connecting member 12. Figure 1 As shown, the shell body 11 can be a box-shaped structure, and the top side of the shell body 11 is open. The shell body 11 has insulation properties, for example, the shell body 11 can be processed and formed by materials with good insulation properties such as plastic.

[0048] At least part of the second connector 12 is integrally formed with the shell body 11 by injection molding, and the first connector 4 is electrically connected to the second connector 12. Specifically, the second connector 12 is conductive, for example, the second connector 12 may be made of aluminum or other materials. The second connector 12 is integrally formed with the shell body 11 by injection molding, for example, during processing, the second connector 12 may be placed in a corresponding mold, and then molten injection molding liquid may be introduced, and the shell body 11 may be formed after the injection molding liquid solidifies, thereby realizing integral injection molding of the second connector 12 and the shell body 11.

[0049] During assembly, the first connector 4 is electrically connected to the second connector 12. During use, the connection position between the first connector 4 and the second connector 12 can be used as a high voltage sampling point or as an output interface of a circuit.

[0050] In some embodiments, the second connecting member 12 includes a plurality of columns 121 , the plurality of columns 121 are located in the shell body 11 , and the first connecting member 4 is fixed to and electrically connected to the columns 121 .

[0051] For example, Figure 3 As shown, the column 121 may be cylindrical, and the column 121 may be integrally formed as the upper structure of the second connecting member 12 by casting, and the column 121 may extend in the up-down direction.

[0052] The first connecting member 4 can be electrically connected to the plurality of columns 121 through a fastener. The fastener can be a bolt, and a threaded hole can be provided in the column 121. During assembly, the fastener can pass through the first connecting member 4 from above and be threadedly assembled in the threaded hole of the column 121, thereby facilitating the connection and fixation of the first connecting member 4 and the second connecting member 12.

[0053] In some embodiments, the first connecting member 4 includes a plurality of connecting portions 42 , which are arranged at intervals along the circumference of the first connecting member 4 , and the plurality of connecting portions 42 are connected to at least a portion of the plurality of columns 121 in a one-to-one correspondence.

[0054] For example, Figure 3 and Figure 4 As shown, there may be four connecting parts 42, and the four connecting parts 42 may form a group of two, and the two connecting parts 42 in the same group may be arranged side by side in a horizontal direction. One group of connecting parts 42 may be located on the left side of the first connecting member 4, and the other group of connecting parts 42 may be located on the rear side of the first connecting member 4. The connecting parts 42 may be provided with through holes for fasteners to pass through, thereby facilitating the installation and fixation of the first connecting member 4 and the corresponding column 121.

When the shell body 11 is injection molded, each sub-connector is injection-molded and fixed to the shell body 11.

[0056] In some embodiments, the first connecting member 4 includes a plurality of connecting arms 43, which are arranged at intervals along the circumference of the first connecting member 4, each connecting arm 43 cantilevers outward from the first connecting member 4 and bends toward one side of the second connecting member 12, and a connecting portion 42 is provided at the free end of each connecting arm 43.

[0057] For example, Figure 4 As shown, the first connecting member 4 may be provided with two connecting arms 43, and both connecting arms 43 may be generally Z-shaped structures, that is, the connecting arms 43 may first extend horizontally, then bend downward, and finally bend horizontally again. The free end of each connecting arm 43 may be integrally formed with two connecting portions 42, and each connecting portion 42 may be arranged horizontally. The bending of the connecting arm 43 may play a role in compensating for the elevation difference between the column 121, and secondly, may also play a role in limiting in the horizontal direction, which may enhance the structural stability after assembly.

[0058] It should be noted that the two connection parts 42 corresponding to the left connection arm 43 may be sampling points for high voltage sampling, and the two connection parts 42 corresponding to the rear connection arm 43 may be output interfaces of the circuit.

[0059] In some embodiments, the connecting portion 42 includes a connecting piece 421 and a connecting section 422, the width dimension of the connecting section 422 is smaller than the width dimension of the connecting piece 421, the connecting section 422 is connected between the connecting piece 421 and the connecting arm 43, and the connecting piece 421 is fixed to the column 121, for example, the connecting piece 421 can be clamped and fixed between the fastener and the column 121.

[0060] For example, Figure 3 As shown, the connecting piece 421 may be in the shape of a rectangular plate, and the connecting section 422 may be integrally formed between the connecting piece 421 and the connecting arm 43. Figure 3 In the view, the width dimension of the connecting piece 421 and the width dimension of the connecting section 422 are both dimensions in the front-to-back direction, and the width dimension of the connecting piece 421 is larger than the width dimension of the connecting section 422. Therefore, the connecting portion 42 can be easily bent and deformed at the connecting section 422, thereby providing a deformation amount for the fastener to press and fix the connecting piece 421, thereby improving the convenience of operation.

[0061] In some embodiments, the first connector 4 includes a plurality of guide members 44 , which are disposed on an edge of the first connector 4 facing the mainboard 3 and are spaced apart along the edge. The first connector 4 is connected to the mainboard 3 via the plurality of guide members 44 .

[0062] like Figure 4 and Figure 5 As shown, multiple guide members 44 can be integrally formed on the right side of the first connecting member 4, and the guide members 44 can be in the shape of a wire. Multiple guide members 44 can be arranged at intervals along the front-to-back direction. During assembly, multiple guide members 44 can be directly welded and fixed to corresponding positions of the mainboard 3, thereby providing convenience for connection.

[0063] In some embodiments, Figure 5 As shown, the first connector 4 may further include a plate body 45 and a wire 46. The plate body 45 may be regarded as an insulating plate of a circuit board. A plurality of wires 46 may be provided, and the plurality of wires 46 may be integrated in the plate body 45. The side of the wire 46 facing the main board 3 may be exposed outside the plate body 45 and form the above-mentioned guide 44. Each wire 46 may connect the corresponding connection part 42, the electrical connection point, etc. with the corresponding guide 44. Thus, the use needs of signal transmission or power supply are met.

[0064] In some embodiments, an insulating layer is provided on the outer surface of the first connector 4, so that the first connector 4 has better insulation protection.
