The invention relates to an electric vehicle battery connection plug, which includes a base fixing seat, a front base, a rear base and several pins, and an axially arranged hollow in the middle of the base fixing seat penetrates the base fixing seat. cavity, the front base and the rear base are respectively installed in the front and rear of the cavity, the rear base is provided with pin installation through holes, and the front base is provided with pin accommodating channels corresponding to the pin installation through holes. Holes, the pins are installed in the pin installation through holes one by one, and the front end of the pin extends into the front base and is located in the pin receiving through hole, and the outer periphery of the base fixing seat is provided with a radially protruding installation There are mounting holes on the mounting plate. The base fixing seat is also provided with two axially arranged guide sleeves, and the two guide sleeves are located on both sides of the front base and the rear base. A sealing ring is set on the front end of the base fixing seat, and a sealing pad is embedded in the back of the mounting plate. The invention has firm connection, mutual insulation and isolation between each contact pin, good waterproof and dustproof effect, and improves safety and reliability.
Description
technical field [0001] The invention relates to the field of manufacturing electric vehicle battery components, in particular to an electric vehicle battery connection plug. Background technique [0002] In order to achieve the purpose of energy saving and emission reduction, the development of electric vehicles is relatively rapid at present. The power of electric vehicles is provided by lithium-ion battery packs.
