A good male-female connector structure can ensure accurate docking and normal operation between devices, and has a wide range of applications in communication, power, industrial control and many other fields, effectively promoting the rapid development of various industries.

[0003] In the field of male-female connector, various means are commonly used to realize the connection between male connector and female connector. The most common way is to use plug-in connection, which relies on the shape and size tolerance of male connector and female connector to realize close fit and elastic connection piece elastic fit inside the jack. The operation is relatively simple and fast. However, plug-in connection requires force to insert and pull out when inserting or pulling out the male connector, which is difficult for people with little strength. Especially in daily life, in order to improve the overall appearance of the house, the installation position of some male-female connectors is hidden, such as being blocked by furniture. When connected, the line of sight is blocked and the jack position distribution cannot be seen directly, which increases the difficulty of insertion. It is not easy to align the plug with the jack when inserting, and because of the friction between the plug on the male connector and the inner wall of the jack on the female connector and the resistance of the elastic connection piece inside the jack, the difficulty of insertion and pulling out is increased, which may cause people to confuse whether it is because the position is not aligned and the resistance is not inserted or the jack is aligned but the resistance itself is not inserted, and then people may use brute force to insert and pull out. The connection between the male connector and the female connector is loose, which is easy to cause the connection to slip or damage. SUMMARY

When the connecting block 9 is inserted into the male seat 1 and rotated, the first thread on the connecting block 9 cooperates with the second thread on the inner wall of the connecting sleeve 37 to drive the connecting sleeve 37 and the rubber ring 36 to move towards the male seat 1, so that the rubber ring 36 gradually approaches and abuts against the inclined surface 41, thereby reducing the possibility of water vapor and dust entering the slot 7. When the male seat 1 is pulled out in the reverse direction, the connecting block 9 is rotated to drive the connecting sleeve 37 away from the male seat 1, so that the rubber ring 36 is away from the inclined surface 41, thereby avoiding the resistance of the rubber ring 36 when the male seat 1 is pulled out. The fourth spring 40 can also be arranged in the limiting groove 39, when the connecting sleeve 37 moves outward, the limiting block 38 compresses the fourth spring 40, and after the restriction between the protruding portion 13 and the recessed portion 14 is released by pressing the pressing block 23, the protruding portion 13 is not turned to the position of the guide groove 16, but is directly pulled out of the male seat 1. At this time, after the connecting block 9 is not limited by the male seat 1, the connecting sleeve 37 is driven by the fourth spring 40 to move into the slot 7, the connecting sleeve 37 drives the connecting block 9 to rotate and reset to the initial position, thereby facilitating the next insertion of the male seat 1.

[0047] As Figure 4As shown, the limiting assembly 15 includes a first limiting block 26 and a second limiting block 27, both of which are located at the edge of the end face of the mounting block 52, and are connected to the circuit. The connecting block 9 is provided with a first limiting slot 28 for the first limiting block 26 to slide and a second limiting slot 29 for the second limiting block 27 to slide at the edge of the end face of the mounting block 52. The end wall of the first limiting slot 28 is fixedly provided with a positive electrode interface 53, and the end wall of the second limiting slot 29 is fixedly provided with a negative electrode interface 54. The positive electrode interface 53 and the negative electrode interface 54 are respectively connected to the elastic connecting piece 11 in the corresponding connecting pipe 6. The limiting assembly 15 not only controls the rotating position of the connecting block 9, but also controls the connection state of the circuit in the female seat 2. After the male seat 1 is inserted, the circuit is in an open state, which is conducive to improving the safety of electricity use and reducing the possibility of inserting metal or the male seat 1 into the female seat 2 by children. When the male seat 1 is rotated in a specific direction after being inserted, the elastic connecting piece is first connected to the plug 5, and then the circuit in the female seat 2 is connected to the elastic connecting piece 11. When the male seat 1 is reversely rotated and pulled out, the circuit in the female seat 2 is first disconnected from the elastic connecting piece 11, and then the elastic connecting piece 11 is disconnected from the plug 5. The double-circuit protection is conducive to improving the safety of electricity use.

[0048] The implementation principle of the embodiment of the application is that when the male seat 1 is moved towards the female seat 2, the insertion block 8 is inserted into the insertion slot 7, and the plug 5 is inserted into the connecting pipe 6, the insertion block 8 is not in contact with the inner wall of the insertion slot 7, and there is no resistance of the elastic connecting piece 11 in the connecting hole. After the male seat 1 is inserted and fixed under the action of the buckle assembly 3, the elastic connecting piece 11 is moved towards the plug 5 under the action of the driving mechanism 12 and is clamped against the plug 5, and the circuit is connected, thereby reducing the difficulty of inserting and pulling out the male seat 1, and further reducing the situation that the male seat 1 and the female seat 2 are connected in a loose or even damaged manner, and then improving the service life of the male seat 1 and the female seat 2.

[0049] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
