The first cover plate 130 is provided with a matching assembly groove 132. In terms of waterproof performance, the first cover plate 130 and the second cover plate 230 can be provided with waterproof sealing pieces 133, which can cover the first through hole 121 or the jack 221 when the male head 100 and the female head 200 are separated. The design of the cover plate can effectively prevent dust and moisture from entering the connector, improve the protection level, and ensure that the connector can still work normally in harsh environments.

[0028] The specific structure of the telescopic mechanism is as follows: it comprises a shaft 140, a telescopic spring 150, a pressing block 160 and a base plate 111. The shaft 140 is divided into a limiting section and a light pole section. The limiting section is provided with a limiting protrusion 141 on the side surface, and the light pole section is located at the bottom of the shaft 140 and abuts against the first panel 120. The insertion rod is assembled on the base plate 111, which is provided with a first limiting sliding groove 112 matched with the limiting section. The top side of the first limiting sliding groove 112 is provided with a positioning sliding groove 113 matched with the limiting protrusion 141. The telescopic spring 150 is assembled between the base plate 111 and the first panel 120. The pressing block 160 abuts against the upper surface of the base plate 111, and the pressing block 160 is provided with a second limiting sliding groove 161 matched with the limiting section. This structure allows the user to realize the extension and retraction of the insertion pin 110 through simple pressing and rotating actions. When it is necessary to fix the insertion pin 110 at a certain position, the limiting protrusion 141 is made to enter the positioning sliding groove 113 by rotating the pressing block 160. Conversely, the retraction of the insertion pin 110 can be easily completed by reversing the operation. This intuitive and simple operation mode greatly improves the user experience.

[0029] Specifically, the male head 100 comprises an inner seat 170 and a sleeve seat 180 sleeved on the inner seat 170. The first panel 120 is assembled on the inner seat 170, and the pressing block 160 is assembled in the sleeve seat 180. The sleeve seat 180 is provided with a plurality of first sealing rings 181, which abut between the outer wall of the inner seat 170 and the inner wall of the sleeve seat 180. The first through hole 121, the second through hole 131 and the insertion hole 221 are all provided with sealing sleeves 240. The side surface of the first cover plate 130 is provided with a second sealing ring 134, which abuts between the first cover plate 130 and the inner seat 170. The design of the sealing sleeve 240 and the multi-layer sealing ring can further enhance the waterproof performance of the connector and ensure its good electrical performance in a humid environment. In order to ensure the connection reliability of the male head 100 and the female head 200, the sleeve seat 180 is provided with a threaded ring seat 182, and the female head 200 is provided with an outer thread 201 matched with the threaded ring seat 182. The cooperation of the threaded ring seat 182 and the outer thread 201 makes the connection of the connector more firm and reduces the possibility of loosening.

[0030] The rotating mechanism comprises a rotating shaft 250 and a torsion spring 260 assembled on the rotating shaft 250, one end of the rotating shaft 250 is connected with the first cover plate 130 or the second cover plate 230, the other end passes through the first panel 120 or the second panel 220 and is provided with a rotating disc 251 at the end. The design of the torsion spring 260 and the rotating shaft 250 enables the cover plate to automatically reset after the male head 100 and the female head 200 are separated, thereby providing continuous protection. The rotating disc 251 is provided with a limiting rotating groove 252 on the side, the first cover plate 130 or the second cover plate 230 is provided with a rotating clamping block 253, and the rotating clamping block 253 is located in the limiting rotating groove 252. The design of the limiting rotating groove 252 and the rotating clamping block 253 ensures the accurate opening and closing of the cover plate and prevents the cover plate from being excessively rotated.

[0031] In addition, the female head 200 is also designed for reliability, specifically, the female head 200 is provided with a through groove 270 accommodating the plug-in sleeve 210, the radial width of the through groove 270 is greater than the diameter of the plug pin 110, and the middle part of the plug-in sleeve 210 is hinged to the inner wall of the through groove 270. The through groove 270 is provided with an upper elastic block 271 and a lower elastic block 272, the upper elastic block 271 is located between the upper part of the plug-in sleeve 210 and the inner wall of the through groove 270, the lower elastic block 272 is located between the lower part of the plug-in sleeve 210 and the inner wall of the through groove 270, and the upper elastic block 271 and the lower elastic block 272 are located on both sides of the plug-in sleeve 210. When the plug pin 110 is inserted into the plug-in sleeve 210, the upper elastic block 271 and the lower elastic block 272 on both sides of the plug-in sleeve 210 can exert a force towards the axis on the plug-in sleeve 210. This force ensures the close contact between the plug-in sleeve 210 and the plug pin 110, thereby improving the stability of the connection and reducing the risk of signal transmission interruption or performance decline caused by poor contact. Moreover, due to the existence of the upper elastic block 271 and the lower elastic block 272, even if the plug-in part is worn out due to frequent plugging and unplugging, a certain deviation exists between the plug pin 110 and the plug-in sleeve 210, the position of the plug-in sleeve 210 can be automatically adjusted by the elastic force, so that the plug pin 110 and the plug-in sleeve 210 always maintain contact, thereby reducing the possibility of signal attenuation.

[0032] The top of the plug-in sleeve 210 is designed to be flared. The flared design can guide the plug pin 110 to correctly align with the plug-in sleeve 210 to a certain extent, reduce the friction between the plug pin 110 and the plug-in sleeve 210, reduce the risk of damage, and make it easier for the plug pin 110 to enter the plug-in sleeve 210. A plurality of elastic expansion clamping heads 273 are assembled on the inner wall of the through groove 270, the plug pin 110 is provided with a clamping groove 114 matched with the clamping head 273, and the plug-in sleeve 210 is provided with a through hole 211 for the clamping head 273 to extend into. The expansion clamping head 273 can be clamped into the clamping groove 114 when the plug pin 110 is inserted, thereby achieving firm connection between the plug pin 110 and the plug-in sleeve 210.

[0033] The protection scope of the utility model includes but is not limited to the above implementation manners, the protection scope of the utility model is subject to the claims, any replacement, deformation, improvement of the technical personnel in the art to the present technology is easily thought of and falls into the protection scope of the utility model.
