Detailed ways

Referring to Figure 1, the utility model proposes a high-voltage connector for high-power testing, including a plug and a socket. The plug and the socket are respectively used to connect one end of the power cord, and the connection of the power cord can be realized through the docking of the plug and the socket.

The plug includes: a pin 1 , a first connection terminal 2 , a plug inner shell 3 , a plug outer shell 4 and a first shielding layer 5 . The pin 1 is installed in the plug inner shell 3 , and the first connection terminal 2 protrudes from the plug inner shell 3 and is connected with the pin 1 . The first connecting terminal 2 is used to connect the power line, and the first connecting terminal 2 and the pin 1 are both conductive structures. When the first connecting terminal 2 is connected to the power line, the power line is electrically connected to the pin 1 . The plug inner shell 3 protects the pins 1 .

The plug shell 4 is sleeved on the outer periphery of the plug inner shell 3 , and the first shielding layer 5 is filled between the plug shell 4 and the plug inner shell 3 , specifically, the inner periphery of the plug shell 4 is completely covered by the first shielding layer 5 . Both the plug inner shell 3 and the plug shell 4 are insulating structures.

The socket includes: a socket column 6 , a socket inner shell 7 , a socket shell 8 , a second shielding layer 9 and a second connection terminal 10 . The socket post 6 is installed in the socket inner shell 7 , and the socket post 6 is provided with a socket matching the pin 1 , and the second connecting terminal 10 protrudes from the socket inner shell 7 and is connected with the socket post 6 . The second connecting terminal 10 is used to connect the power line. Both the second connecting terminal 10 and the jack post 6 are conductive structures. When the second connecting terminal 10 is connected to the power line, the power line and the jack post 6 are conductively connected.

The socket shell 8 is sleeved on the outer periphery of the socket inner shell 7 , and the second shielding layer 9 is filled between the socket shell 8 and the socket inner shell 7 , specifically, the inner periphery of the socket shell 8 is completely covered by the second shielding layer 9 . Both the socket shell 8 and the socket inner shell 7 are insulating structures. In the working state of the high-voltage connector, the pin 1 is inserted into the socket, and the plug shell 4 is covered by the socket inner shell 7; The connection with the power line connected to the second connection terminal 10. When the plug and the socket are connected, the pin 1 and the socket column 6 are wrapped by the plug inner shell 3, the plug shell 4, the socket inner shell 7 and the socket shell 8 layers, so as to avoid accidents of electric shock to the operator. Specifically, the plug inner shell 3, the plug outer shell 4, the socket inner shell 7 and the socket shell 8 are all plastic structures.

In this embodiment, there is a gap between the plug shell 4 and the plug inner shell 3, which can be used to accommodate the arc overflowing from the pin 1, and then shield the arc through the first shielding layer 5, which can further prevent the occurrence of arc on the plug shell 4, Ensure safe operation. Specifically, the first shielding layer 5 is a metal shielding layer, so as to ensure the safety of the outer surface of the plug through electrostatic shielding and prevent operational accidents.

The retaining spring 12 is parallel to the contact pin 1 . In this way, when the plug is docked with the socket, the circlip 12 protrudes to prove that the connection is in place. The setting of the circlip 12 can detect whether the plug and the socket are effectively connected; secondly, the connection between the plug and the socket can be locked. Prevent accidental fall off. When it is necessary to separate the plug from the socket, you only need to press the 12 protruding points of the retaining spring, and then they can be separated quickly to realize the power-off of the power cord. In this embodiment, the setting of the snap spring is not only convenient for identifying whether the power of the power cord is in the energized state or the disconnected state, but also can improve the safety during use.
