[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0022] The present utility model provides a waterproof connector.

[0023] In this embodiment, referring to Figures 1-4 , this waterproof connector includes a female end housing 1 and a male end housing 2 that is inserted and cooperated with the female end housing, and also includes a female end sealing ring 3 provided on the opening of the female end housing, a male end sealing ring 4 provided on the opening of the male end housing, and a middle sealing ring 5 provided at the connection between the female end housing and the male end housing. At least two first positioning convex rings 6 are spaced apart on the outer walls of the female end sealing ring and the male end sealing ring. First positioning concave rings 7 that are mutually engaged with the above-mentioned first positioning convex rings are provided on the inner walls of the openings of the female end housing and the male end housing. At least two second positioning convex rings 8 are provided on the outer wall and the inner wall of the middle sealing ring. Second positioning concave rings 9 that are mutually engaged with the above-mentioned second positioning convex rings are provided on the connecting side walls of the female end housing and the male end housing.

[0024] The waterproof connector in the above technical solution significantly enhances the waterproof and dustproof capabilities of the connector by adding a female end sealing ring, a male end sealing ring, and a middle sealing ring at the interface between the female end housing and the male end housing, and using the cooperation of the positioning convex ring and the positioning concave ring. This design not only effectively prevents the entry of moisture and dust, but also ensures the stable performance and long-term use of the connector in harsh environments.

[0025] Specifically, contact protrusions 10 are provided on the female end sealing ring and the male end sealing ring between the first positioning convex rings, as well as on the middle sealing ring between the second positioning convex rings.

[0026] In the above technical solution, by adding contact protrusions on the female end sealing ring, male end sealing ring, and middle sealing ring between the positioning convex rings, the contact tightness between the sealing ring and the housing is further enhanced, and the sealing effect is improved. The setting of the contact protrusions enables the sealing ring to better fit the housing surface under pressure, reduces potential leakage paths, and enhances the waterproof and dustproof performance of the connector.

[0027] Specifically, a wire hole 11 for inserting a wire is provided in the middle of the female end sealing ring and the male end sealing ring, and bell mouths 12 that contract towards the wire hole are provided at both ends of the wire hole.

[0028] In the above technical solution, wire holes are provided on the female end sealing ring and the male end sealing ring, and bell mouths are designed at both ends of the wire holes, making the wire insertion smoother and reducing the possibility of wire damage. At the same time, the bell mouth structure helps the wire to extrude the sealing ring during the insertion process, enhancing the sealing between the wire and the sealing ring, and further improving the overall waterproof and dustproof effect of the connector.

[0029] Specifically, a number of protrusions 13 are provided at equal intervals on the inner wall of the wire hole.

[0030] In the above technical solution, by providing protrusions on the inner wall of the wire hole, a certain frictional force can be generated on the inserted wire, thereby forming a physical lock after the wire is inserted, preventing the wire from loosening or disengaging under vibration or external force, and improving the mechanical stability of the connector and the reliability of the electrical connection. In addition, the waterproof and dustproof ability between the wire and the guiding hole can be increased.

[0031] Specifically, a positioning plate 14 extending towards the female end housing is provided on the male end housing, and a positioning groove 15 corresponding to the positioning plate is provided on the female end housing.

[0032] In the above technical solution, by providing a positioning plate on the male end housing and a corresponding positioning groove on the female end housing, rapid positioning and guiding during the plugging process of the connector are achieved, avoiding misalignment and damage during plugging, simplifying the operation process, and improving the assembly efficiency and connection accuracy.

[0033] Specifically, it further includes an I-shaped lock block 16. Hook steps 17 are provided on both sides of the female end housing, a toggle hook 18 is provided on the male end housing, and chutes 19 are provided at one end of the toggle hook away from the hook step and on the outer wall of the male end housing. The I-shaped lock block is embedded in the above chutes.

[0034] In the above technical solution, the introduction of the I-shaped lock block and the corresponding hook step, the rocker hook and the chute design form a reliable mechanical locking mechanism. When the male housing is docked with the female housing, the I-shaped lock block can move along the chute to the hook step position and lock, ensuring that the rocker hook of the connector will not accidentally separate when subjected to external force impact or vibration, improving the stability and safety of the connector.

[0035] All technicians should note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model only. Any modification using the idea of the present utility model will be included in the scope of protection of this patent right.
