DETAILED DESCRIPTION

[0031] The utility model will be further explained in connection with the drawings and embodiments.

[0032] Please refer to Figures 1 to 7 A plug connector, including male end and female end. The core component of male end is male rubber core 1, its outside side cleverly rotates and connects a buckle 2. On the side wall of male rubber core 1, arc slot 3 is designed, and spring 4 is embedded in these slots to provide necessary elastic force. In order to ensure that spring 4 is stably installed in arc slot 3, boss 6 is specially provided to limit spring 4. One end of spring 4 is in contact with driving block 5 of the inner wall of buckle 2, so that when buckle 2 rotates, driving block 5 can produce corresponding action under the action of spring 4.

[0033] In order to prevent driving block 5 from separating from arc slot 3 during operation, one end of arc slot 3 is specially designed with blocking part 7. And on the side wall of male rubber core 1 close to blocking part 7, slope 8 is also provided, and the main function of this slope 8 is to guide driving block 5 to enter arc slot 3 smoothly. In addition, the side wall of male rubber core 1 also reserves avoiding slot 9, which provides enough space for the insertion of driving block 5.

[0034] When installing buckle 2, first of all, spring 4 needs to be stably placed in arc slot 3, and limited by boss 6. Then, driving block 5 of buckle 2 is slowly inserted along avoiding slot 9. Next, by relatively rotating male rubber core 1 and buckle 2, driving block 5 will gradually move to arc slot 3 along slope 8. Because driving block 5 has a certain deformation ability, when it moves to the appropriate position of arc slot 3, it will restore to its original shape, thereby completing the stable installation of buckle 2 and male rubber core 1. At this time, blocking part 7 can effectively prevent driving block 5 from accidentally separating from arc slot 3.

[0035] The female end is mainly composed of female rubber core 10, and the side wall is provided with lock slot 11. The inner wall of buckle 2 is designed with lock block 12 that perfectly matches lock slot 11, and through the interlocking of the two, the tight connection of male end and female end is realized.

[0036] In addition, power copper needle 13 is also installed equiangularly inside male rubber core 1 and female rubber core 10 for power transmission. The end of male rubber core 1 matched with female rubber core 10 is designed into a cylindrical shape, and sealing ring 14 is installed on this cylindrical shape to further improve the sealing effect.

[0037] In order to facilitate the user to judge whether the assembly is correct, the female head rubber core 10 and the side wall of the buckle ring 2 are provided with switch indication arrows 15. At the same time, in order to prevent the equipment from being damaged due to misplug, the male head rubber core 1 is specially designed with a foolproof groove 16, and the female head rubber core 10 is correspondingly provided with a foolproof convex 17.

[0038] The side wall of the buckle ring 2 is also provided with a hand boss 18, and the side wall of the female head rubber core 10 is provided with a recess 20, so that the user only needs to gently push the boss with fingers when unlocking, and the unlocking operation can be easily completed. The outer side wall of the buckle ring 2 is covered with anti-skid convexes 19, which not only increase the friction, but also make the operation more convenient and labor-saving.

[0039] It should be emphasized that the male head end and the female head end also have other structures, and the remaining structures are all common structures of connectors, such as Figure 1 As shown, the remaining structures have nothing to do with the problems proposed in the background art, so they are not described in detail.

[0040] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
