Further, a bayonet 15 is arranged at the lower edge of the plug-in interface 13, which is in T-shaped structure. The arrangement of the bayonet 15 forms a clamping position at the lower end of the plug-in interface 13, which can more reliably position the plug-in connector, ensuring the reliability of the connection between the plug-in connector and the connector.

[0024] Reference Figure 1 , 3 The contact spring 2 comprises a fixed segment 21 and an abutting segment 22. The fixed segment 21 is first extended outwardly from the cover body 1 on both sides of the plug-in interface 13, and then bent inwardly into the plug-in interface 13 and connected to the abutting segment 22. The fixed segment 21 is integrally arranged with the cover body 1, which can facilitate the production of the cover body 1 and the molding thereof. The abutting segment 22 is formed with a bent angle, and the opening of the bent angle faces the side wall of the fixed cavity.
