Abstract

The invention relates to a high-voltage and large-current plug and a high-voltage and large-current connector equipped with the plug. The high-voltage and large-current plug comprises at least two sleeve-shaped pins. The tail of each pin is used for inserting a shunt cable. The middle of each pin is embedded into a plug A rubber core. The head of each pin is detachably inserted into a plug B shunt substrate contact piece of a plug B. The plug B shunt substrate contact piece is embedded into a plug B shunt substrate. The plug A rubber core is installed in a plug A shell. Contact resistance produced when the high-voltage and large-current plug is plugged into a main conductor device of a power supply at the plug B side can be reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a high-voltage and high-current plug connector and a high-voltage and high-current electrical connector provided with the plug. Background technique [0002] In new energy vehicles, when the battery pack transmits high voltage and high current above 250A, the effective conduction current cable of the male and female terminal conductors should be more than 70 square meters. When using single-core connectors, the cumulative tolerance of the station and the application environment The reason is that the contact resistance of the male and female terminal conductors continues to increase, and the high temperature will be transmitted to the cable, which will cause the original cable to be fully overloaded with high current and generate high temperature, which will increase the safety hazard of new energy vehicles due to high temperature. Contents of the invention [000...
