Example 6

The structure and implementation of Embodiment 5 and Embodiment 3 are basically the same. This embodiment is another preferred implementation of the electrical properties of the female terminal 120: the female terminal 120 is arranged in two rows and two row, the electrical properties of the receptacle terminals 120 in the same row are the same. By plugging the male connector backwards, you can get the opposite electrical properties from the forward plugging. When the wiring is wrong or the power input direction is changed, it is only necessary to pull out the male end connector, change the direction and plug the male end connector into the female end connector again to improve work efficiency.

In a specific implementation manner, two rows and two rows of female terminals 120 are arranged inside the plug port 111 of the female plastic shell 100, and the electrical properties of the female terminal a in the upper left corner and the female terminal c in the upper right corner are the same , the electrical property of the female terminal b in the lower left corner is the same as that of the female terminal d in the lower right corner.

In one embodiment, the female terminal 120 is a "U"-shaped connecting piece, and the "U"-shaped connecting piece is clamped on the outer wall of the female-end plastic shell 110 . By arranging the receptacle terminal 120 on three sides of the receptacle housing 110 , the applicable installation range of the connector system can be wider.

For other structures of the male connector, the female connector and the connector system described in this embodiment, refer to the prior art.

The working principle of a male-end connector, female-end connector and connector system described in the present invention is:

1. By setting the socket port 111 with a symmetrical physical port structure on the female end connector 100, the plug structure 211 of the male end connector 200 can be plugged into the socket port 111 in the forward and reverse directions, and the connector can be realized. The forward and reverse directions of the connector can be connected to improve the work efficiency; at the same time, the connection reliability of the connector can be improved through the close fit of the plug port 111 and the plug structure 211 .

2. Through the guidance and cooperation of the guide groove 111.1 and the limit groove 211.1, the guide cooperation makes the insertion of the female connector 100 and the male connector 200 more accurate and convenient; at the same time, it makes the female connector 100 and the male connector 200 fit tightly and provide sufficient holding force, further improving the connection reliability of the connector.

3. Through the concave-convex position 111.2 of the guide groove 111.1 and the concave-convex opening 211.2 of the limiting groove 211.1 to form a limit clamping, it is ensured that the female connector 100 and the male connector 200 can maintain a relative connection during long-term use position, further improving the connection reliability of the connector.

4. By setting the circuit connection part 122 of the female terminal 120 on different sides, the female rubber shell 110 can be installed vertically or horizontally, so that the scope of application of the connector system is wider; at the same time, by adjusting the female terminal rubber The installation state of the shell 110 can prevent the insertion direction of the female connector 100 and the male connector 200 from being vertically downward, and the plug structure 211 coming out of the insertion port 111 due to gravity.

5. The present invention has a simple structure and is easy to assemble. One unit can be prepared to a size of about 3-5 mm, and can be used as a conductive connector for small parts.

In the description of the present invention, it should be explained that, unless otherwise clearly stipulated and maintained, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediary, and it can be the internal communication of two components.

In describing the present invention, it is to be understood that the terms "central", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", The orientation or positional relationship indicated by "bottom", "inner", "outer", etc. is based on the position and orientation relationship shown in the drawings, and is only for the convenience of describing the simplified description of the present invention, rather than indicating or implying the referred device Or elements must have a certain orientation, be constructed and operate in a certain orientation, and thus should not be construed as limiting the invention.
