Embodiment Construction

[0031] figure 1 , 2. The power connector plug shown in 3 includes a plug insulator 2. The plug insulator has a buckle stop structure for matching with the matching socket. The mating part of the plug insulator 2 is two parallel and independent mating heads. 3. There is a corresponding plug contact 7 inside each mating head. The front end of the plug contact 7 abuts against the step of the closing jack 11 at the front end of the mating head. The closing jack 11 has a depth and an opening to prevent finger electric shock. Caliber, the depth and opening diameter meet the safety test requirements for the electric shock test needle in the UL60950 standard. The probe of the test needle is in the shape of a standard analog finger. When the test needle extends from the front end of the mating head into the closing socket, the test needle should not touch it. A plug contact 7; a plug insulating pressing block 1 is embedded in the tail of the plug insulator, and the mating surface of t...

Abstract

The invention relates to a power supply connector and a plug and a socket thereof. Between a plug insulating body and a socket insulating body has a buckle separation retaining structure; the socket insulating body is provided with two parallel and independent jacks; the tail part of the socket insulating body corresponding to each jack is provided with a corresponding socket contact piece; the insertion part of the socket contact piece matched with the plug extends into the jack; between the end face of the insertion part and the end face of the insertion end of the socket insulating body has a distance for preventing fingers from contacting electricity; the opening of the jack in the end face of the insertion end is an opening with a caliber for preventing the fingers from contacting electricity; the insertion part of the plug insulating body is two independent insertion heads correspondingly inserted and matched with the jacks; the inside of each insertion head is provided with a corresponding plug contact piece; the front end of the plug contact piece props against the step of the sealed jack of the front end of the insertion head; and the sealed jack is provided with depth and opening caliber for preventing the fingers from contacting electricity. The power supply connector can realize safe electriferous insertion in the power transmission of a power interface.

Description

technical field [0001] The invention relates to a power connector, a plug and a socket of the power connector. Background technique [0002] Various power connectors have their corresponding applicable occasions. In some special occasions, such as the power transmission connection of the power interface between modules and modules or between units in some equipment and instrument chassis, due to One of the modules or units is already in a live working state, so it is best to operate without stopping when connecting, which means that live connections are required. In order to meet safety requirements, plugs and sockets for plug-in connections are required. The contacts are wrapped in the corresponding insulators, and it is required that even if the little finger of the human hand is inserted into the socket of the insulator by mistake, the live contacts cannot be touched, that is, the test needle (also called "golden finger") in the UL60950 standard The test requirements, an...
