[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] This utility model discloses a wave-shaped anti-reverse and waterproof connector, such as... Figure 1-4 As shown, the device includes a male connector 1 and a female connector 2, both of which are cylindrical. One end of the male connector 1 has a slot 11, which the female connector 2 inserts into. Multiple pins 12 are fixedly mounted on the male connector 1. The number of pins can be between two and eight, providing better electrical performance. The number of pins can also be more than eight, without limitation. One end of each pin 12 extends into the slot 11. The female connector 2 faces... Multiple sockets 21 are provided on one end face of the male connector 1. Pins 12 are inserted into the sockets 21 and electrically connected. In addition, a positioning block 14 is integrally formed on the inner wall of the insertion groove 11 along the axial length of the male connector 1. A positioning groove 23 is formed on the outer peripheral surface of the female connector 2 along the axial length of the female connector 2. The positioning block 14 is inserted into the positioning groove 23. When the male connector 1 and the female connector 2 are connected, the positioning block 14 is inserted into the positioning groove 23, which can make the multiple pins 12 and the multiple sockets 21 more accurately aligned.

[0021] In addition, the female head 2 is movably fitted with an external threaded sleeve 3, and the male head 1 is provided with an internal threaded sleeve 4. The inner circumferential surface of the external threaded sleeve 3 is provided with an internal thread, and the outer circumferential surface of the internal threaded sleeve 4 is provided with an external thread. The external threaded sleeve 3 and the internal threaded sleeve 4 are threadedly engaged. At the same time, a convex ring 22 is integrally formed on the circumferential surface of the female head 2, and a retaining ring 31 is integrally formed on the inner wall of the end of the external threaded sleeve 3 away from the male head 1. The surfaces of the convex ring 22 and the retaining ring 31 facing each other are wavy, and the surfaces of the convex ring 22 and the retaining ring 31 facing each other are in contact. One end of the male head 1 abuts against the surface of the convex ring 22 away from the retaining ring 31. After inserting the female head 2 into the male head 1, the external threaded sleeve 3 is rotated to connect the external threaded sleeve 3 and the internal threaded sleeve 4 together. When the retaining ring 31 of the external threaded sleeve 3 touches the convex ring 22, the external threaded sleeve 3 is rotated further to make the retaining ring 31 engage with the convex ring 22, so that the retaining ring 31 and the convex ring 22 are completely fitted together. The retaining ring 31 and the convex ring 22 make it difficult for the external threaded sleeve 3 and the internal threaded sleeve 4 to loosen, making the connection between the male head 1 and the female head 2 more stable.

[0022] In addition, the internal threaded sleeve 4 is fitted onto the male connector 1. A limiting ring 13 is integrally formed on the outer circumferential surface of the end of the male connector 1 closest to the female connector 2. Both the surface of the limiting ring 13 facing the internal threaded sleeve 4 and the end face of the internal threaded sleeve 4 closest to the limiting ring 13 are wavy. The end face of the internal threaded sleeve 4 closest to the limiting ring 13 is in contact with one side surface of the limiting ring 13. This ensures that the internal threaded sleeve 4 will not detach from the male connector 1 after being threaded into the external threaded sleeve 3, thus improving the ease of assembly between the male connector 1 and the internal threaded sleeve 4. Simultaneously, an abutment ring 41 is integrally formed on the end of the internal threaded sleeve 4 furthest from the female connector 2. The abutment ring 41 is fitted onto the male connector 1, and one end of the abutment ring 41 is in contact with one end of the external threaded sleeve 3, thus improving the waterproof performance between the male connector 1 and the female connector 2. Furthermore, a silicone sealing ring is provided between the male connector 1 and the convex ring 22, which further enhances the waterproof performance between the male connector 1 and the female connector 2. In addition, the outer circumferential surfaces of the abutment ring 41 and the external threaded sleeve 3 are integrally formed with multiple anti-slip ridges 32. The anti-slip ridges 32 make it easy for people to hold the abutment ring 41 and prevent slippage when rotating the external threaded sleeve 3.

[0023] The implementation principle of the wave-shaped anti-reverse and waterproof connector of this utility model embodiment is as follows: When connecting the male head 1 and the female head 2, the female head 2 is inserted into the male head 1, and then the external thread sleeve 3 is rotated to connect the external thread sleeve 3 and the internal thread sleeve 4 together. When the retaining ring 31 of the external thread sleeve 3 touches the convex ring 22, people continue to rotate the external thread sleeve 3 with force so that the retaining ring 31 is engaged in the convex ring 22, so that the retaining ring 31 and the convex ring 22 are completely fitted together. The retaining ring 31 and the convex ring 22 make it difficult for the external thread sleeve 3 and the internal thread sleeve 4 to loosen, making the connection between the male head 1 and the female head 2 more stable.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
