DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figure 1 As shown, a waterproof connector with an anti-detachment structure includes a connector 10, one end of the connector 10 is plugged with a socket 20, a first fixing pin 10a and a second fixing pin 20a are fixedly connected to the side walls of the connector 10 and the socket 20, respectively, and an anti-detachment structure 30 is provided between the first fixing pin 10a and the second fixing pin 20a to prevent the connector from loosening;

[0026] Among them, Figure 2-3 As shown, the anti-slip structure 30 includes an anti-slip hook 301, one end of the anti-slip hook 301 is movably sleeved on the outside of the first fixing pin 10a, and the other end is clamped on the outside of the second fixing pin 20a. When the socket 20 and the connector 10 are connected, the anti-slip hook 301 is rotated toward the second fixing pin 20a. Two groups of symmetrical snap rings 302 are arranged at the other end of the anti-slip hook 301. A receiving groove 304 for receiving the snap ring 302 after being compressed is opened on the inner side of the anti-slip hook 301, and a stopper is also arranged in the middle part of the receiving groove 304, dividing the groove into two sections, and springs 303 are arranged in the two sections of the groove. The two sections are also fixedly connected to the stopper and the snap ring 302 respectively, and are used to reset the snap ring 302 when there is no external pressure. When the anti-detachment hook 301 rotates toward the second fixing pin 20a, the snap ring 302 is retracted into the receiving groove 304 under the pressure of the second fixing pin 20a, and the generated gap allows the second fixing pin 20a to pass through. After the second fixing pin 20a passes through, the spring 303 resets the snap ring 302. A pin hole 305 for placing the second fixing pin 20a is formed between the snap ring 302 and the anti-detachment hook 301. The pin hole 305 wraps and clamps the second fixing pin 20a, thereby preventing the socket 20 and the connector 10 from detaching.

[0027] The anti-detachment structure 30 is also easy to disassemble. A pull ring 40 is also provided on the anti-detachment hook 301. A rotating shaft 40a is rotatably provided on the side wall of the anti-detachment hook 301 for installing the pull ring 40. The clamping ring 302 at the end of the anti-detachment hook 301 is pulled into the receiving groove 304, and the pull ring 40 is pulled to drive one end of the anti-detachment hook 301 to detach from the second rotating pin 20a.

[0028] In order to ensure the waterproof performance of the connector 10 and the socket 20, as Figure 4-5 As shown, a circle of connection end 20b is extended from one end of the socket 20 close to the connector 10, and a step is formed between the connection end 20b and the socket 20. The connector 10 has a notch corresponding to the step, and multiple groups of sealing rings 20c are also sleeved on the outside of the connection end 20b. Similarly, a sealing groove is opened between the notch of the connector 10 and the sealing ring 20c. The sealing ring 20c seals the gap between the connector 10 and the socket 20 in the sealing groove. Alternatively, the connection end 20b can also be set on the connector 10, and the socket 20 can be opened with a corresponding sealing groove, which can prevent the entry of external liquid.

[0029] Working principle: When the connector 10 is in use, the connector 10 is first inserted into the corresponding slot of the socket 20, and the anti-disconnection hook 301 on the first fixed pin 10a is pushed toward the second rotating pin 20a. The anti-disconnection hook 301 is close to the snap ring 302 on the second fixed pin 20a and is received into the receiving groove 304 under the pressure of the second rotating pin 20a. When the second fixed pin 20a is completely inserted into the pin hole 305, the snap ring 302 is reset under the action of the spring 303 to lock the second rotating pin 20a, so that the connector 10 and the socket are fixed. 20, to prevent the two from falling off between the connector 10 and the socket 20 due to unstable insertion. When removing the anti-detachment hook 301 from the second fixing pin 20a, it is only necessary to immerse the clamping ring 302 into the receiving groove 304, and drive the two anti-detachment hooks 301 to be separated from the second fixing pin 20a through the pull ring 40. In addition, a connecting end 20b is protruded on the socket 20, and the sealing ring 20c provided on the connecting end 20b can be embedded in the sealing groove of the connector 10 to seal the connection between the two to prevent liquid from seeping in.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
