By way of example and not limitation, in some alternative embodiments, the housing 10 includes an upper housing 11 and a lower housing 12 that snap together, with the snap-fit seat 40 extending from an inner wall of the lower housing 12. It should be noted that, although the card socket 40 may be extended from the circuit board 20 for fixing the grounding assembly 30, this may result in a complicated manufacturing process of the circuit board 20, so that it is preferable to extend the card socket 40 from the inside of the lower case 12. In addition, the split type up-and-down buckling design of the shell 10 is convenient for the disassembly, assembly and maintenance of the socket.

Further, the grounding assembly 30 is located on a side of the circuit board 20 near the upper housing 11, and the clamping seat 40 extends upward from the bottom inner wall of the lower housing 12 and passes through the circuit board 20.

In addition, the upper housing 11 extends toward the lower housing 12 to form a receiving groove 111 for receiving the plugging portion 31, and a clamping groove 112 adapted to the conductive connection portion 32 is formed on a sidewall of the receiving groove 111. The accommodating groove 111 is provided for protecting the ground wire assembly 30, and can reduce the contact area between the ground wire assembly 30 and the outside, thereby preventing damage from the outside. In addition, the up-and-down moving direction of the grounding assembly 30 is limited by the engagement of the clamping groove 112 of the side wall of the accommodating groove 111 and the groove 41, so that the grounding assembly 30 is limited from being moved and misplaced by external influence when the upper and

lower housings

11 and 12 are assembled together.

Further, the bottom of the accommodating groove 111 extends outwards to form a limiting seat 113, the limiting seat 113 is provided with a limiting groove 114, and the side wall of the plugging portion 31 connected with the conductive connecting portion 32 is located in the limiting groove 114.

The limiting groove 114 may also limit the forward and backward movement of the socket part 31, i.e., the forward and backward movement of the conductive connection part.

In addition, the upper housing 11 extends downward to form a locking block 115, and the lower housing 12 is provided with a locking groove 121 adapted to the locking block 115. The upper shell 11 and the lower shell 12 are fixedly connected together in a clamping manner. In addition, the upper shell 11 is provided with a screw hole, the lower shell 12 is provided with a step hole matched with the screw hole, and the lower shell 12 and the upper shell 11 are fixedly connected together through the cooperation of the screw passing through the step hole and the screw hole.
