[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figure 1 - Figure 4 The embodiment provides a high-voltage large-current connector, which comprises a male plug-in 1 and further comprises:

[0025] A female seat body 2 is sleeved on the outside of the male plug-in 1;

[0026] A connecting assembly is arranged in the inside of the female seat body 2;

[0027] Two PCB boards 3 are respectively sleeved on the outside of the male plug-in 1 and the female seat body 2.

[0028] The working principle is that when the connector as a whole needs to be fixed and installed, the two PCBs 3 are first installed outside the male plug 1 and the female seat body 2, and then the male plug 1 is inserted into the female seat body 2. At this time, the connecting assembly can effectively fix the male plug 1 and the female seat body 2, so that the connector as a whole can be installed, and the two PCBs 3 can be connected. The structure is simple and clear, convenient to install, stable and reliable to connect, and has good conductivity and corrosion resistance, which can effectively reduce the impedance and temperature rise test of the connector, and enable the connector to be used in harsh environments. Moreover, the device has a wide range of applications and can adapt to different electrical equipment and cable connection requirements. By welding a ring 7 outside the female seat spring 4, the stability and current overload capacity of the connector are effectively improved, and the practicality and service life of the connector as a whole are effectively improved.

[0029] In order to effectively connect the male plug 1 and the female seat body 2, the connecting assembly includes a female seat spring 4 fixedly installed inside the female seat body 2. The bottom of the female seat spring 4 is fixedly installed with a female seat gasket 5. The inside of the female seat spring 4 and the female seat gasket 5 is provided with a guide groove for the movement of the male plug 1. The outside of the female seat spring 4 is welded with a ring 7. When the male plug 1 and the female seat body 2 need to be connected, the male plug 1 is inserted into the female seat body 2. At this time, the female seat spring 4 is extruded. When the male plug 1 is inserted into the female seat gasket 5, the male plug 1 can be effectively fixed by the elasticity of the female seat spring 4. At this time, the male plug 1 and the female seat body 2 can be connected. The structure is simple and clear, and the staff can easily disassemble and assemble the connector, effectively improving the disassembly and assembly efficiency of the connector. The setting of the ring 7 can effectively improve the stability and current overload capacity of the connector as a whole, and further improve the practicality of the connector as a whole.

[0030] Considering that the connector needs to have good conductivity when in use, the materials of the male plug 1, the female seat body 2, the female seat spring 4 and the female seat gasket 5 are all high-conductivity copper. The male plug 1, the female seat body 2, the female seat spring 4 and the female seat gasket 5 all use special high-conductivity copper materials, which can effectively reduce the impedance and temperature rise test of the connector, effectively improve the conductivity of the connector, and the device does not need to use electroplated silver, which reduces the production cost of the connector as a whole to a certain extent.

[0031] In order to make the connector can be used in harsh environment, so the male plug 1, female seat body 2, female seat spring 4 and female seat gasket 5 are coated with anticorrosive paint, because the male plug 1, female seat body 2, female seat spring 4 and female seat gasket 5 are coated with anticorrosive paint, therefore can effectively improve the overall corrosion resistance of the connector, so that the connector can be used in harsh environment, effectively improve the overall practicality and service life of the connector.

[0032] In order to effectively improve the stability of PCB 3 after installation, so the male plug 1 and female seat body 2 are equal interval opening of anti-skid groove 6 outside, through the setting of anti-skid groove 6, can effectively improve the stability of PCB 3 after installation, avoid the PCB 3 fall off and so on, so as to be convenient and effective to the connection between PCB 3.
