Description

a waterproof connector

technical field

The utility model relates to a waterproof joint used for wire connection.

Background technique

With the continuous improvement of people's living standards, higher requirements are gradually put forward for the performance of electronic components. It is usually required that electrical equipment can be used normally in special environments. For example, electrical equipment used underwater requires good The water resistance of the wires is especially required to prevent water leakage at the joints of the wires, so as to ensure the normal operation of the electrical equipment. Based on this, the existing wire connections usually need to use waterproof joints to realize the fixed connection of the wires and the electrical conduction connection. However, the existing The structure of the waterproof joint is relatively complicated, and the operation of the wire connection is not easy enough, and it is usually fixed by screw connection.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a waterproof joint with simple structure and convenient operation.

In order to achieve the above object, the utility model adopts the following technical solutions:

A waterproof connector, including a female connector and a male connector, a female terminal is fixed inside the female connector, a male terminal for insertion of the female terminal is fixed inside the male connector, and a sealing ring for hermetically connecting the female terminal and the male terminal is sleeved on the outside of the female terminal , the male joint is provided with a through hole extending along its axial direction, and the female joint is provided with an elastic hook inserted through the through hole and hooked on the through hole.

The elastic hook includes a shrapnel and a hooking flange. The shrapnel extends along the axial direction of the female joint. One end of the shrapnel is integrally formed with the female joint, and the other end is a free end. The hooking flange is located on the outer surface of the free end of the shrapnel.

The utility model has the effect that:

Compared with the prior art, the waterproof connector of the present invention only needs to be connected in the axial direction. It is easy to operate and has a simple structure. It can not only ensure good electrical conduction and firmness of connection, but also has Relatively good water resistance. the

Detailed ways

Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

Referring to Figures 1 and 2, the waterproof joint of the present invention includes a female joint 1 and a male joint 2. The female joint 1 is fixed with a female terminal 11, and the male joint 2 is fixed with a male terminal 21 for insertion of the female terminal 11. The female terminal 11 A sealing ring 13 is sleeved on the outside, a through hole 22 extending along the axial direction is provided on the male joint 2, and an elastic hook 12 matching the through hole 22 is provided on the female joint 1. When the female joint 1 and the male joint 2 are docked, The female terminal 11 on the female connector 1 is inserted into the male terminal 21 on the male connector 2. The sealing ring 13 is used to seal the female terminal 11 and the male terminal 21 and realize the electrical conduction between them. At the same time, the elastic The hook 12 penetrates through the through hole 22 and hangs on the end surface of the through hole 22 away from the female joint 1. Specifically, the elastic hook 12 includes a shrapnel and a hooking flange, and the shrapnel extends along the axial direction of the female joint 1. One end of it is integrally formed with the female connector 1, and the other end is a free end. The hooking flange is located on the outer surface of the free end of the shrapnel. When plugged in, the elastic hook 12 is inserted into the through hole 22. The inner wall of the through hole 22 is in contact with the inner wall of the female joint 1 to deform the shrapnel, and continue to apply axial thrust. The hooking flange moves along the through hole 22, and finally slides to the end surface of the through hole 22 away from the female connector 1. At this time, the shrapnel rebounds, making the hooking flange The edge is finally hung on the end face of the through hole 22 away from the female connector 1 .

When the waterproof joint of the utility model is used for cable connection, it only needs to apply an axial thrust to the female joint 1 and the male joint 2, so that the two are butted, and the electrical conduction and fixed connection of the cable can be realized without rotation, which is convenient to use , and the structure is simple.

The number of elastic hooks 12 can be set as required, and two elastic hooks 12 are optimal.

Referring to Figure 3, when used for double-cable docking, a male connector and a female connector with the same structure as above can also be made into a connector with an integrated structure, and two identical connectors can realize the docking of two cables , when docking, you only need to align the male connector of one of the connectors with the female connector of the other connector.

For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and ideas described above, and all these changes and deformations should fall within the protection scope of the claims of the present utility model.
