Technical Field
[0001] The present invention relates to a connector, and more particularly to a waterproof connector adaptable to small-angle plugging and unplugging. Background Art
[0002] A connector, also known as a plug, socket, or electrical connector, generally refers to an electrical connector, which is a device that connects two active devices to transmit current or signals. Connectors are components that electronic engineering technicians often come into contact with. Their function is very simple: to build a communication bridge between a blocked or isolated circuit in a circuit, so that current can flow. Connectors are indispensable components in electronic devices. Looking along the path of current flow, you will always find one or more connectors. The form and structure of connectors are ever-changing. With different application objects, frequencies, powers, application environments, etc., there are various forms of connectors.
[0003] Currently, electric vehicles on the market tend to be small, intelligent, and lightweight. As an important part of electrical connection, the requirements for connectors are also getting higher and higher. Different installation methods require different structures of connectors. Connectors generally have a good anti-misplugging structure, but due to space limitations and waterproof requirements, they often cannot meet the usage requirements of plugging and unplugging at an angle.
[0004] Therefore, a waterproof connector adaptable to small-angle plugging and unplugging is designed to solve the above problems. Summary of the Invention

[0025] Example: As Figure 1As shown in the figure, a small-angle adaptable pluggable waterproof connector includes a male connector 1 and a female connector 2 that can be paired and connected;
[0026] As Figure 2 shown in the figure, the male connector 1 includes a male positioning member 11 connected to the vehicle frame housing 3. A male terminal is arranged inside the male positioning member 11. A first pin 12 serving as a power PIN and a second pin 13 serving as a signal PIN are arranged on the male terminal. A gasket 14 is arranged at the connection between the male positioning member 11 and the vehicle frame housing 3. A groove is formed at the outer end of the male positioning member 11, and a sealing ring 15 is arranged in the groove. The male connector 1 is made by an assembly method. The male terminal is first pre-installed into the male positioning member 11 through a jig, then the wire is welded, and the tail is fixed, waterproofed, and the strength is improved by applying glue. A groove is formed in the outer circle of the male positioning member 11 and the sealing ring 15 is installed, which can meet the high-grade waterproof requirements for the mating of the male and female ends. The sealing ring 15 can be made of silicone material. A gasket 14 made of rubber material is arranged between the male positioning member 11 and the vehicle frame housing 3, and the waterproof requirements between the male connector 1 and the vehicle frame housing 3 are achieved by squeezing through locking screws.
[0027] As Figure 3 shown in the figure, the female connector 2 includes a movable member 25 connected to the battery housing 4. One end of the movable member 25 is connected to a female positioning member 21. A female terminal is arranged inside the female positioning member 21. A first jack 22 serving as a power PIN and a second jack 23 serving as a signal PIN are arranged on the female terminal. The other end of the movable member 25 is connected to a pressing piece 24. A rubber material movable member 25 is arranged on the female connector 2. One end of the movable member 25 is fixed to the female positioning member 21 by applying glue, which plays a waterproof role; the other end is adhesively fixed to the pressing piece 24 made of plastic material by gluing; and the waterproof requirements between the female connector 2 and the battery housing 4 are achieved by squeezing the movable member 25 through locking screws.
[0028] As Figure 4As shown in the figure, a shrapnel 26 with a hook 27 is provided on one side of the pressing piece 24, and a guide post 29 with a slot 28 is provided on one side of the female terminal positioning member 21. The hook 27 is arranged in the slot 28 to realize the hooking connection between the pressing piece 24 and the female terminal positioning member 21. The hook 27 has a certain range of movement along the axial direction of the guide post 29 in the slot 28. The materials of the male terminal positioning member 11, the female terminal positioning member 21, and the pressing piece 24 are all plastics. The pressing piece 24 is provided with a shrapnel 26 with a hook 27, which is used in cooperation with the guide post 29 with a slot 28 on the female terminal positioning member 21. When the male connector 1 and the female connector 2 are mating at an angle, the guide post 29 on the female terminal positioning member 21 forms a stop with the pressing piece 24. When the male connector 1 and the female connector 2 are pulled out at an angle, the shrapnel 26 on the pressing piece 24 hooks the slot 28 of the guide post 29 on the female terminal positioning member 21 to form a stop under force. This structure can prevent the moving part 25 from participating in the force and extend the service life of the product.
[0029] The first pin 12 and the first jack 22 are correspondingly arranged, and the second pin 13 and the second jack 23 are correspondingly arranged. The diameter of the first pin 12 is larger than that of the second pin 13. The mating surfaces of the male connector 1 and the female connector 2 can be set as special-shaped surfaces, which can play a good role in preventing misinsertion errors.
[0030] The preferred embodiment is: as Figure 2 shown, the outer end of the male terminal positioning member 11 includes a convex ring 16, and the gasket 14 is located between the convex ring 16 and the vehicle frame housing 3. It is convenient for installation and improves the sealing and waterproof effect.
[0031] The preferred embodiment is: as Figure 2 shown, the convex ring 16 and the gasket 14 have the same shape. It is waterproof and beautiful.
[0032] The preferred embodiment is: both the first jack 22 and the second jack 23 are crown spring jacks. They are used in corresponding cooperation with the first pin 12 and the second pin 13 of the male terminal, and can meet the requirements of high plugging and unplugging times.
[0033] The preferred embodiment is: as Figure 3 ~ Figure 4 shown, both the pressing piece 24 and the female terminal positioning member 21 are arranged inside the moving part 25. It occupies a small space and has a dust-proof effect.
[0034] The preferred embodiment is: as Figure 3 shown, the moving part 25 is a bellows-type elastic connecting piece. The bellows-type elastic structure moves flexibly, ensuring flexible movement without jamming during angled plugging and unplugging.
[0035] The present invention designs a small-angle pluggable waterproof connector. The male connector is fixed on the vehicle frame by screwing, and the female connector is provided with a rubber movable part and is fixed on the battery end by screwing. When the male connector and the female connector are plugged and unplugged, the small-angle plugging and unplugging of the connector are realized through the rubber movable part on the female connector. The structure is simple, the plugging and unplugging are convenient, the waterproof performance is good, and the space is saved.
[0036] The above embodiments are only illustrative of the principles and effects of the present invention, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
