The inner walls of the first fixing plate 8 and the second fixing plate 9 are provided with sliding grooves adapted to the I-shaped connecting plate 10, so that the I-shaped connecting plate 10 can be snapped into the interior of the first fixing plate 8 and the second fixing plate 9, which can prevent the I-shaped connecting plate 10 from easily falling out from the inner walls of the first fixing plate 8 and the second fixing plate 9, thereby achieving the effect of limiting the position between the female base body 1 and the PCB board 3.

[0025] Four fixing components 4 are arranged on the outer surface of the female socket body 1, and the fixing component 4 includes a fixing block 401.

The inner walls of the two grooves 402 are fixedly connected with springs 403, and the ends of the two springs 403 away from each other are fixedly connected with sliding plates 404. The outer surfaces of the two sliding plates 404 are respectively slidably connected to the inner walls of the two grooves 402, and the sides of the two sliding plates 404 away from the springs 403 are fixedly connected with limiting blocks 405.

The spring clip 1103 and the first limiting groove 1104 can prevent the first PIN needle 5 and the second PIN needle 6 from retreating.

[0028] The outer surfaces of the first fixed bin 1101 and the second fixed bin 1102 are both fixedly connected with the first bending portion 1105, the outer surfaces of the first PIN needle 5 and the second PIN needle 6 are both provided with a second limiting groove 1106, the second limiting groove 1106 is clamped with the second bending portion 1107, and the outer surfaces of the first PIN needle 5 and the second PIN needle 6 are both provided with a second bending portion 1107, and the second bending portion 1107 is bent on the outer surface of the first bending portion 1105 by the second bending portion 1107, so as to support the second bending portion 1107 and prevent the second bending portion 1107 from bending or retreating during the plugging and unplugging of the female socket to cause the PIN to retreat.

[0029] The principle of the implementation mode of the present application is as follows: the I-shaped connecting plate 10 clamped between the first fixing plate 8 and the second fixing plate 9 can prevent the female socket body 1 from falling off from the PCB board 3 and causing the PIN to retreat; the fixing block 401 can be clamped on the outer surface of the PCB board 3 through the fixing component 4, so as to further limit the PCB board 3; the first PIN needle 5 and the second PIN needle 6 can be limited by the spring piece 1103 clamped inside the first limiting groove 1104; the first PIN needle 5 and the second PIN needle 6 can be further limited by the first bending portion 1105 clamped inside the second limiting groove 1106; the second bending portion 1107 is bent toward the outer surface of the first bending portion 1105, so as to prevent the female socket from causing the first PIN needle 5 and the second PIN needle 6 to retreat or bend during the plugging and unplugging process, thereby avoiding the PIN retreat phenomenon.
