Technical Field

[0001] This utility model relates to electrical connectors, specifically to a waterproof connector with a snap-fit ​​structure. Background Technology

[0002] Connectors are widely used in electronic devices and electrical systems, especially in humid or underwater environments where high waterproof performance is required. Most existing waterproof connectors use simple plug-in connections, which are not secure enough. When subjected to external forces such as pulling or vibration, they are prone to loosening or even detachment, affecting the normal operation of the equipment. This also significantly reduces their waterproof performance, allowing water to seep into the connector and damage electronic components. Furthermore, traditional connectors lack effective foolproof designs during installation, making it easy for operators to insert the male and female terminals incorrectly, wasting time and potentially causing equipment malfunction or damage.

[0003] Therefore, there is an urgent need for a connector that provides a stable connection, good waterproof performance, and foolproof functionality to meet market demands. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof connector with a snap-fit ​​structure, which solves the problems of unstable connection, poor waterproof effect and lack of foolproof design of existing waterproof connectors, so as to improve the reliability and safety of the connector.

[0005] To solve the above technical problems, the present invention achieves this through the following solution: The present invention provides a waterproof connector with a snap-fit ​​structure, including a male end and a female end, wherein the male end and the female end are connected by a snap-fit.

[0006] The male and female ends also have a waterproof structure;

[0007] The male and female terminals also have a foolproof structure.

[0008] Furthermore, the snap-fit ​​connection structure includes:

[0009] The male end socket has protruding rafters on both sides, and the two sides of the protruding rafters have beveled surfaces;

[0010] The elastic buckles are provided on both sides of the female end. The buckle end has a back buckle that can be fastened into the rafter from the inclined surface. The tail end has an outwardly curved pressure handle. The rod between the pressure handle and the back buckle is connected to the main body of the female end through a support rod. The support rod serves as a fulcrum and can satisfy the following condition: when the pressure handle is pressed down, the back buckle at the other end can open and detach from the rafter.

[0011] Furthermore, the outer surface of the pressure handle is provided with raised and recessed textures.

[0012] Furthermore, the waterproof structure includes:

[0013] A groove is provided around the outer wall of the main body;

[0014] A waterproof sealing ring is embedded in the groove.

[0015] Furthermore, the groove is provided with a positioning groove for preventing the waterproof sealing ring from moving, and correspondingly, the waterproof sealing ring is provided with a protrusion that can be inserted into the positioning groove.

[0016] Furthermore, the outer diameter of the waterproof sealing ring is provided with multiple raised rings.

[0017] Furthermore, the foolproof structure is a cross-section of the main body that is a rounded isosceles trapezoidal structure;

[0018] Correspondingly, the socket of the male end is configured as an isosceles trapezoidal hole with rounded corners that is adapted to the main body.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Example 1: The specific structure of this utility model is as follows:

[0033] Please refer to the appendix. Figure 1-6 This utility model discloses a waterproof connector with a snap-fit ​​structure, comprising a male end 2 and a female end 1, which are connected by a snap-fit ​​connection; the male end 2 has a male end terminal 23, and the female end 1 has a female end terminal 14 that mates with the male end terminal 23. Lugs 22 are provided on both sides of the male end 2, and the lugs 22 have screw through holes.

[0034] The male end 2 and the female end 1 also have a waterproof structure;

[0035] The male end 2 and the female end 1 also have a foolproof structure.

[0036] The snap-fit ​​connection structure includes:

[0037] The male end 2 has protruding rafters 21 on both sides of the insertion port, and the two sides of the protruding rafters 21 have inclined surfaces;

[0038] The elastic buckle 11 is provided on both sides of the female end 1. The buckle end of the elastic buckle 11 has a buckle that can be fastened into the rafter 21 from the inclined surface. Its tail has a pressing handle that curves outward. The rod between the pressing handle and the buckle is connected to the main body 13 of the female end 1 through a support rod. The support rod serves as a fulcrum and can satisfy the following condition: when the pressing handle is pressed down, the buckle at the other end can open and detach from the rafter 21.

[0039] The outer surface of the pressure handle is provided with raised and recessed textures.

[0040] The waterproof structure includes:

[0041] A groove 15 is provided around the outer wall of the main body 13;

[0042] A waterproof sealing ring 12 is embedded in the groove 15.

[0043] The groove 15 is provided with a positioning groove 151 for preventing the waterproof sealing ring 12 from moving. Correspondingly, the waterproof sealing ring 12 is provided with a protrusion 122 that can be inserted into the positioning groove 151.

[0044] The error-proof structure is to set the cross-section of the main body 13 into an isosceles trapezoidal structure with rounded corners;

[0045] The outer diameter of the waterproof sealing ring is provided with multiple raised rings 121.

[0046] Correspondingly, the socket of the male end 2 is configured as an isosceles trapezoidal hole with rounded corners that is adapted to the main body 13.

[0047] Example 2:

[0048] Female end 1, male end 2, elastic buckle 11, waterproof sealing ring 12, body 13, female end terminal 14, groove 15, protruding rafter 21, protruding lug 22, male end terminal 23, protruding ring 121, protruding piece 122, positioning groove 151.

[0049] Implementation of the snap-fit ​​connection: In the actual manufacturing process, the male end is integrally molded from high-strength engineering plastic. The precision and smoothness of the beveled surfaces on both sides of the protruding rafter 21 are ensured through injection molding, allowing the snap fastener 11 to engage smoothly. The female end 1's snap fastener 11 is made of plastic material with good elasticity and toughness. The main body 13 is integrally molded through injection molding, ensuring that the shape and size of the snap fastener and the tail handle of the snap fastener 11 meet design requirements. During installation, the protruding rafter 21 of the male end 2 is aligned with the snap fastener of the snap fastener 11. Due to the guidance of the beveled surfaces on both sides of the protruding rafter 21, the snap fastener can easily engage with the protruding rafter 21, achieving the connection between the male end 2 and the female end 1. When separation is required, the operator presses the raised and recessed texture on the outer side of the handle with their fingers, using the lever principle and the support rod as a fulcrum to open the snap fastener and disengage it from the protruding rafter 21, thereby separating the male end 2 and the female end 1.

[0050] Example 3:

[0051] Implementation of the waterproof structure: The groove 15 on the outer wall of the main body 13 is also formed by injection molding to ensure the accuracy of the groove's depth, width, and shape, so that the waterproof sealing ring 12 can be tightly embedded. The positioning groove 151 is processed together with the groove 15 during molding, ensuring the dimensional and positional accuracy of the positioning groove 151. The waterproof sealing ring 12 is made of silicone rubber and manufactured by compression molding. During manufacturing, a protrusion 122 adapted to the positioning groove is reserved on the waterproof sealing ring 12. During installation, the waterproof sealing ring 12 is embedded into the groove 15, so that the protrusion 122 is accurately placed in the positioning groove 151, ensuring that the waterproof sealing ring 12 will not shift during use, thereby achieving a good waterproof sealing effect.

[0052] Example 4:

[0053] Implementation of the foolproof structure: Both the main body 13 and the male socket are formed using injection molding. During the mold design phase, the cross-section of the main body 13 is designed as a rounded isosceles trapezoidal structure, and the male socket is designed as a perfectly matching rounded isosceles trapezoidal hole. During production, the precision of the mold and the injection molding process parameters are strictly controlled to ensure that the shape and size of the main body 13 and the male socket meet the design requirements. When performing the insertion operation of the male end 2 and the female end 1, insertion can only be completed smoothly if the male socket is aligned with the main body 13 of the female end 1 in the correct direction; if the direction is incorrect, insertion will fail due to shape mismatch, thus achieving the foolproof function.

[0054] In summary, this utility model of a waterproof connector features a robust snap-fit ​​connection structure: the male end's protruding tab engages with the female end's elastic snap, and the snap's inverted end engages with the beveled sides of the protruding tab, achieving a secure connection between the male and female ends. Compared to traditional plug-in connections, this method effectively resists external pulling and vibration, preventing the connector from loosening or falling off, ensuring connection stability, and guaranteeing the normal operation of the equipment. Simultaneously, the raised and recessed texture on the outer side of the pressure handle increases the friction between the fingers and the handle, making it easier and less strenuous for operators to press the handle, thus improving operational convenience.

[0055] This utility model of a waterproof connector features excellent waterproof performance: a waterproof sealing ring is embedded in a groove around the outer wall of the female end, effectively preventing water from seeping in at the connection point between the male and female ends. The positioning groove within the groove cooperates with the protrusion of the waterproof sealing ring to prevent movement during installation or use, ensuring the sealing ring remains in the correct position. This further enhances the waterproof effect, providing reliable waterproof protection for the internal electronic components of the connector and extending its service life.

[0056] This utility model of a waterproof connector features a reliable foolproof structure: the female end's main body has a rounded-corner isosceles trapezoidal cross-section, and the male end's socket is a matching rounded-corner isosceles trapezoidal hole, ensuring that the male and female ends can only be smoothly inserted in the correct orientation. When inserted incorrectly, the mismatch in shapes prevents connection, thus avoiding equipment malfunctions or damage caused by incorrect installation. This improves installation accuracy and efficiency, and reduces labor and equipment maintenance costs.
