Description

Technical Field

[0001] This application relates to the field of electrical connections, and more particularly to a connector. Background Technology

[0002] In the prior art, connectors include a housing and terminals. The terminals have a locking spring and a terminal stop. The housing has a housing stop. The rear end of the housing stop has an inclined surface. When the terminal is inserted into the housing, the inclined surface presses against the locking spring, thereby closing the locking spring. After the locking spring passes the housing stop, it abuts against the front end of the housing stop, and the terminal stop abuts against the inclined surface of the housing stop, thereby retaining the terminal within the housing. Because the terminal stop is located on the terminal, it may deform during transportation and assembly. Furthermore, because the terminal stop needs to mate with the inclined surface of the housing stop, the fit between the terminal stop and the housing stop is not stable enough. Utility Model Content

[0009] According to another exemplary embodiment of the present invention, the front stop and the rear stop are evenly arranged along the circumference of the terminal socket.

[0010] According to another exemplary embodiment of the present invention, the front stop and the rear stop are staggered in the circumferential direction of the terminal socket.

[0011] According to another exemplary embodiment of the present invention, the front stop and the rear stop are integrally formed on the inner surface of the terminal socket by strong demolding.

[0012] According to another exemplary embodiment of the present invention, the sleeve has a front end adapted to abut against the rear wall of the front stop portion.

[0013] According to another exemplary embodiment of the present invention, the at least two locking springs extend rearward and outward from the sleeve. The rear ends of the at least two locking springs are adapted to abut against the front wall of the rear stop.

[0014] According to another exemplary embodiment of the present invention, at least two locking springs are formed by bending a portion of the sleeve.

[0015] According to another exemplary embodiment of the present invention, in the longitudinal direction of the terminal socket, the distance between the front stop and the rear stop is greater than the distance between the front end of the sleeve and the rear end of the at least two locking springs.

[0018] According to another exemplary embodiment of the present invention, the body of the terminal is a one-piece stamped part; and / or the sleeve is a one-piece stamped part.

[0019] In the foregoing exemplary embodiments of the present invention, the stop portion is disposed in the housing, thereby simplifying the structure of the terminal, effectively preventing deformation of the stop portion during transportation, and also reducing the manufacturing cost of the terminal.

[0020] In addition, the locking spring of the terminal is held in the space between the front stop and the rear stop, which can prevent the locking spring from shifting or shaking.
