[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the protection scope of the present utility model.
[0018] As Figures 1-4 shown, the embodiments of the present utility model include:
[0019] A waterproof signal connector includes a male connector 1 and a female connector 2 that are plugged together. The male connector 1 is encapsulated with a male end panel 3. On the male end panel 3, there are square pins 4. At the root of the square pins 4, there is an end face gasket 5. At the edge of the male end panel 3, there is a male end positioning member 6, and a locking notch 7 is provided on the male end positioning member 6. The female connector 2 is encapsulated with a female end panel 8. On the female end panel 8, there is a female end positioning member 9. The female end positioning member 9 is provided with a pin hole 10. Inside the pin hole 10, there is a tuning fork terminal 11 that cooperates with the square pin 4. On the side of the female end positioning member 9, there is a buckle 12 that cooperates with the locking notch 7.
[0020] When the male and female connectors are plugged together in place, the end face of the female end and the gasket form end face compression to achieve the performance of sealing and waterproofing, and the waterproof level of IPX7 can be achieved.
[0021] Among them, the male end positioning member 6 is in a cylindrical structure, the female end positioning member 9 is in a boss structure, and the inner wall shape of the male end positioning member 6 coincides with the outer wall shape of the female end positioning member 9.
[0022] Specifically, the cross-section of the male end positioning member 6 is in a rectangular shape. The male end positioning member 6 encloses a cavity, and at least two or more square pins 4 are embedded in the cavity.
[0023] In addition, there are two locking notches 7. As Figure 1 shown, one locking notch 7 is penetrated and opened on each of the upper and lower sides of the male end positioning member 6. As Figure 2 shown, two buckles 12 are provided on each of the upper and lower sides of the female end positioning member 9.
[0024] Furthermore, the front end of the square pin 4 has a needle part, the front end of the tuning fork terminal 11 has a fork part, and the fork part elastically clamps and connects the needle part. At least two or more tuning fork terminals 11 are embedded in the cavity formed by the pin hole 10. When the male and female connectors are plugged together, the buckle 12 matches the locking notch 7, and the tuning fork terminal 11 is docked with the square pin 4. After being plugged together in place, there will be an obvious "click" feeling and sound.
[0025] Specifically, the tuning fork terminal 11 is a stamping and blanking structure. The terminal is in a symmetric tuning fork structure. The tuning fork terminal 11 and the square pin 4 are clamped to form electrical conduction for the transmission of current and signals. The stamping type tuning fork terminal 11 can greatly improve production efficiency and significantly reduce costs.
[0026] In summary, the present utility model provides a waterproof signal connector, which realizes the docking feedback of waterproof sealing through the cooperation of the tuning fork terminal 11 and the snap 12 of the locking port 7, and makes a "click" sound and has a snap feeling after the insertion is in place, so as to ensure that the end face gasket 5 can effectively establish a sealing interface, effectively avoid the problem of IPX7 waterproof failure caused by improper operation, and at the same time, due to the stamping terminal structure, cost reduction and efficiency increase can be achieved.
