And adopt the utility model discloses an after the elasticity ground connection connector structure, can remain the advantage of reassembling type connector structure, can also solve the unstable problem of ground wire connection.

Specifically, a resilient ground pin 200 is included and is disposed within the connection base 130. One side of the elastic ground pin protrudes from the end surface of the connection base 130, and the other side protrudes from the sidewall of the connection base 130 and contacts the inner wall of the connection housing 110. One end of the elastic ground pin 200 located on the side wall of the connection base 130 is protruded toward one side of the inner wall of the connection housing 110, and when the connection base 130 is connected to the connection housing 110, the elastic ground pin 200 is elastically contacted with the connection housing 110.

That is, in the process of connecting and assembling the connection base 130 and the connection housing 110, the inner wall of the connection housing 110 and the elastic ground wire pin 200 are connected, so that the inner wall of the connection base 130 presses the elastic ground wire pin 200, and the elastic ground wire pin 200 has a tendency of recovering shape after being pushed by an external force, thereby continuously leaving the elastic ground wire pin 200 attached to one side of the inner wall of the connection housing 110. Even if the connector is frequently inserted and pulled out, the elastic ground pin 200 between the connection base 130 and the connection housing 110 can still be tightly fitted in the inner wall of the connection housing 110, and the connection stability of the ground wire is maintained.

In some embodiments of the present invention, as shown in fig. 1, fig. 2 and fig. 4, the side wall of the connection base 130 is provided with a mounting groove 131, one end of the mounting groove 131 is communicated with the end surface of the connection base 130, one end of the elastic ground pin 200 extends from the mounting groove 131 to the end surface of the connection base 130, and the other end is disposed in the mounting groove 131.
