Description

Technical Field

[0001] The utility model belongs to the field of connectors, and in particular relates to a connector. Background Art

[0002] A connector, also known as a plug-in connector, is an electronic device that is mainly used to connect two active devices to transmit current. The connector consists of two plug-in connector plugs, one of which is equipped with a socket terminal (commonly known as a female terminal), called a female connector plug, and the other connector plug is equipped with a pin terminal (commonly known as a male terminal), called a male connector plug. The disadvantage of a traditional female connector plug is that the female terminal is only connected to the card platform in the inner cavity of the shell through an elastic card foot. When the female terminal is pulled violently, the elastic card foot is easily deformed, so its stability and tensile strength are poor. Utility Model Content

[0022] Reference Figure 1-7As shown, the high-stability connector of the utility model includes a shell 1 and a female terminal 2 arranged in the inner cavity of the shell 1. The front end of the female terminal 2 is provided with a socket 3, and the rear end of the female terminal 2 is provided with a wire-wrapped pin 4. The female terminal 2 is provided with a positioning mechanism 5 near the socket 3, and the positioning mechanism 5 is composed of a positioning frame 6 and an elastic clamping foot 7 integrally formed at the bottom of the positioning frame 6. The front end of the positioning frame 6 is provided with two first positioning feet 8 that are attached to the inner wall of the socket 3, so that the positioning frame 6 forms a closed structure to improve the strength. The inner cavity of the shell 1 is provided with a clamping table 9 connected to the elastic clamping foot 7 and a positioning column 10 inserted into the positioning frame 6. After the positioning column 10 is inserted into the positioning frame 6, at least one end is fixed to the shell 1.
