The first socket hole 101 and the second socket hole 102 can be designed to have the same structure or two different structures of sockets according to production requirements to realize the combined installation of the two sockets.

[0021] In this embodiment, the PCB board 4 is at the lower rear side of the insulating body 1. The conductive terminals 3 are above the PCB board 4 and are bent to be connected between the insulating body 1 and the PCB board 4. A support member 5 is installed below the conductive terminals 3 and is snap-connected to the insulating body 1. The lower ends of the conductive terminals 3 pass through the support member 5 and are electrically connected to the PCB board 4. The support member 5 is inserted into the PCB board 4.

[0022] There are at least two positioning tables 2 on the rear side of the insulating body 1. The positioning tables 2 are integrally injection-molded with the insulating body 1. In this implementation, because two socket structures are involved, two positioning tables 2 are respectively provided corresponding to the rear sides of a single socket. A plurality of conductive terminals 3 are between the two positioning tables 2. The support member 5 includes a support body 501 and a limiting insertion plate 502 vertically connected to the support body 501. A plurality of limiting through holes 501-1 are provided on the support body 501 for inserting the conductive terminals 3. At least two positioning posts 503 are provided at the lower end of the support body 501. Corresponding positioning holes 401 are provided on the PCB board 4 for inserting the positioning posts 503.

[0023] The limit insertion plate 502 is snap-connected to the positioning table 2. The positioning table 2 includes a base 201 and a mounting plate 202 vertically connected above the base 201. The base 201 is provided with a mounting hole 201-1 penetrating through its upper and lower ends. The mounting plate 202 is provided with a jack 202-1. The jack 202-1 is above the mounting hole 201-1 and communicates with the mounting hole 201-1. A clamping plate 203 is suspended and connected in the jack 202-1. The top of the clamping plate 203 is connected above the jack 202-1. The lower part of the clamping plate 203 is suspended above the mounting hole 201-1. A first clamping block 204 protrudes outward on the side of the clamping plate 203 close to the conductive terminal 3. A first transition inclined surface 204-1 is provided below the first clamping block 204.

[0024] The limit insertion plate 502 includes a main board 502-1 and a guide plate 502-2. The guide plate 502-2 is connected obliquely downward above the main board 502-1. The main board 502-1 is also provided with a second clamping block 502-3. The second clamping block 502-3 is on the same side as the guide plate 502-2. A second transition inclined surface 502-2-1 is provided above the guide plate 502-2. The guide plate 502-2 is provided with a guide hole 502-2-2 penetrating through its upper and lower ends.

Both the upper and lower ends of the second clamping block 502-3 are inclined surface structures, namely a third transition inclined surface 502-3-1 and a fourth transition inclined surface 502-3-2 respectively. The main board 502-1 passes through the mounting hole 201-1, and the second clamping block 502-3 is supported above the first clamping block 204 for snap-connection installation. When assembling the support member 5 and the insulating body 1, the main board 502-1 on the limit insertion plate 502 slides into the mounting hole 201-1 along the way, and the first clamping block 204 slides along the guide hole 502-2-2 until the third transition inclined surface 502-3-1 contacts the first transition inclined surface 204-1, realizing the pre-assembly of the conductive terminal 3 and the PCB board 4, that is, at this moment, the bottom part of the conductive terminal 3 is inserted into the corresponding hole position of the PCB board 4. Then, continuously slide the limit insertion plate 502 upward until the fourth transition inclined surface 502-3-2 abuts against the upper part of the first clamping block 204, completing the installation of the support member 5 and the insulating body, and at the same time, the conductive terminal 3 completes the connection with the PCB board 4.
