[0098] Example 6

[0099] This embodiment 5 is basically the same in structure and implementation as embodiment 3. 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 columns on the female housing 110, and the female terminal 120 in the same column has the same electrical properties. By reversing the insertion of the male connector, the electrical properties opposite to those of the forward insertion can be obtained. When the wiring is incorrect or the power input direction is changed, it is only necessary to unplug the male connector, reverse the direction, and plug the male connector back into the female connector, thus improving work efficiency.

[0100] In one specific embodiment, the insertion port 111 of the female end housing 100 is provided with two rows and two columns of female end terminals 120. The female end terminal a in the upper left corner and the female end terminal c in the upper right corner have the same electrical properties, and the female end terminal b in the lower left corner and the female end terminal d in the lower right corner have the same electrical properties.

[0101] In one embodiment, the female terminal 120 is a U-shaped connecting piece, which is clamped onto the outer wall of the female housing 110. By providing the female terminal 120 on three sides of the female housing 110, the applicable installation range of the connector system can be broadened.

[0102] Other structures of the male connector, female connector, and connector system described in this embodiment are referred to in the prior art.

[0103] The working principle of the male connector, female connector, and connector system described in this invention is as follows:

[0104] 1. By providing a plug port 111 with a symmetrical physical port structure on the female connector 100, the plug structure 211 of the male connector 200 can be plugged into the plug port 111 in both directions, thereby realizing the connection of the connector in both directions and improving work efficiency; at the same time, the tight fit between the plug port 111 and the plug structure 211 improves the connection reliability of the connector.

[0105] 2. Through the guiding engagement of the guide groove 111.1 and the limiting groove 211.1, the guiding engagement 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 provides sufficient holding force, further improving the connection reliability of the connector.

[0106] 3. The guide groove 111.1 with the concave and convex parts 111.2 and the limiting groove 211.1 with the concave and convex openings 211.2 form a limiting and locking mechanism, ensuring that the female connector 100 and the male connector 200 can maintain their relative connection positions during long-term use, thereby further improving the connection reliability of the connector.

[0107] 4. By setting the circuit connection part 122 of the female terminal 120 on different sides, the female housing 110 can be installed vertically or horizontally, thereby making the connector system more widely applicable; at the same time, by adjusting the installation state of the female housing 110, the plug structure 211 can be prevented from coming off the insertion port 111 due to gravity, so that the female connector 100 and the male connector 200 are inserted vertically downward.

[0108] 5. The present invention has a simple structure and is easy to assemble. One unit can be made into a conductive connector with a size of about 3-5 mm as a small part.

[0109] In the description of this invention, it should be noted that, unless otherwise explicitly specified and maintained, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0110] In the description of this invention, it should be understood that the terms "center", "horizontal", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the position and orientation relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0111] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
