DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.
[0021] The utility model is further described below in conjunction with embodiments.
[0022] Example: Refer to Figures 1 to 4 A DC waterproof connector includes a female connector body 1 and a male connector body 2 distributed on the left and right. The female connector body 1 and the male connector body 2 are both existing well-known technologies, and their specific structures and principles are not elaborated in detail here.
[0023] It also includes a waterproof component 3 arranged at the right end of the female connector body 1. Specifically, the waterproof component 3 includes a sliding cavity 13 opened at the right end of the female connector body 1. The sliding cavity 13 is slidably connected with a sliding ring 31. The shape of the sliding cavity 13 is annular, and the shape of the sliding ring 31 is adapted to the shape of the sliding cavity 13. A plurality of compression springs 32 are fixedly connected between the sliding ring 31 and the sliding cavity 13. A sealing ring is fixedly bonded to the right end of the sliding ring 31. By means of the sealing ring between the female connector body 1 and the male connector body 2, the waterproof performance between the female connector body 1 and the male connector body 2 is increased.
[0024] When the limit block 16 is located at the limit groove 23, the compression spring 32 is in a compressed state. When the connection between the female connector body 1 and the male connector body 2 is completed, the compression spring 32 is in a compressed state. Under the elastic force of the compression spring 32, the right end of the sealing ring is tightly connected with the male connector body 2. By compressing the spring 32, when the female connector body 1 and the male connector body 2 are connected, the female connector body 1 and the male connector body 2 will not excessively squeeze the sealing ring, thereby ensuring the waterproof effect of the sealing ring.
[0025] Furthermore, the compression spring 32 is never in an extreme compression state, thereby preventing the compression spring 32 from generating elastic fatigue.
[0026] Two guide grooves 14 connected to the sliding cavity 13 are symmetrically provided on the female connector body 1. The left end of the sliding ring 31 is symmetrically fixedly connected with two guide rods 33 that are slidably connected to the guide grooves 14. By setting two guide grooves 14 and slidingly connecting the two guide rods 33, the sliding of the sliding ring 31 can be guided to ensure the stability of the sliding of the sliding ring 31.
[0027] A limit assembly, specifically, the limit assembly includes a sliding groove 15 opened at the right end of the female connector body 1, the sliding groove 15 is slidably connected to a limit block 16, and a plurality of limit springs 17 are fixedly connected between the limit block 16 and the sliding groove 15. When the female connector body 1 and the male connector body 2 are connected, the female connector body 1 is aligned with the male connector body 2, and the female connector body 1 is slid to the right, so that the limit block 16 slides to the limit groove 23, and the limit block 16 abuts against the inner side wall of the limit groove 23 to complete the limiting. The female connector body 1 and the male connector body 2 are limited, and the stability of the connection between the internal components of the female connector body 1 and the male connector body 2 can also be ensured.
[0028] The limit block 16 is provided with an oblique edge. When the female connector body 1 is aligned with the male connector body 2 and the female connector body 1 is slid to the right, the limit block 16 slides to the limit groove 23, and the limit block 16 automatically abuts against the inner wall of the limit groove 23 to complete the limit, simplifying the operation.
[0029] A cable 12 is arranged at the left end of the female connector body 1, the female connector body 1 includes a female connector shell 11, the male connector body 2 includes a male connector shell 21, a limiting groove 23 is provided on the male connector shell 21, and a movable opening 22 connected to the limiting groove 23 is also provided at the left end of the male connector shell 21, and the side projection of the movable opening 22 covers the side projection of the limiting block 16 to ensure that when the female connector body 1 is moved to the right, the limiting block 16 can pass through the movable opening 22.
[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
