Battery connector for electric vehicle

Abstract

The invention relates to a battery connector for an electric vehicle. The battery connector is applicable to being used as a lithium battery discharge connector (plug and socket) for the electric vehicle and an electric passenger car. The battery connector comprises a connector plug and a connector socket, wherein the connector plug comprises a plug shell, a seal cover, a plug insulating installation plate, a power plug and signal communication plugs; locking pins are arranged at two sides of the upper part of the plug shell; the connector socket comprises a socket shell, a socket insulating installation plate, a lock catch, a power socket and signal communication sockets; connecting pin holes are formed in two sides of the upper part of the socket shell; the lock catch is movably connected with the upper part of the socket shell through connecting pins and the connecting pin holes; the lock catch is provided with a lock catch clamping groove; a hand shank is arranged on the lock catch; after the connector plug is inserted into the connector socket, the lock catch clamping groove is clamped and inserted into the locking pins at two sides of the upper part of the plug shell of the connector by stirring the hand shank; and the connector plug is tightly locked on the connector socket, and does not become loose in vehicle travelling and charging processes.

Description

technical field [0001] The invention relates to an electric vehicle battery connector, which is suitable for electric vehicles and electric passenger vehicle lithium battery discharge connectors (plugs, sockets). Background technique [0002] At present, the electric vehicle battery connector adopts aviation plugs, sockets, positive and negative power supply signal lines, which are respectively arranged in three different plugs and sockets, and are respectively installed on the battery box, which is very inconvenient to use when charging. The locking degree between the aviation plug and the socket is poor, and it is easy to loosen. During the charging process, it will generate heat and smoke, which will affect the normal charging. In addition, the waterproof and sealing performance is poor. During the driving process of the vehicle, rainwater on the road is easy to enter the battery connector plug, Between the sockets, it will cause short-circuit heating and burning of the b...

Problems solved by technology

[0002] At present, electric vehicle battery connectors use aviation plugs, sockets, positive and negative power signal lines, which are respectively set in three different plugs and sockets, and are installed on the battery box respectively, which is very inconvenient to use when charging.

The locking degree between the aviation plug and the socket is poor, and it is easy to loosen. During the charging process, it will generate heat and smoke, which will affect the normal charging. In addition, the waterproof and sealing performance is poor. During the driving process of the vehicle, rainwater on the road is easy to enter the battery connector plug, Between the sockets, it will cause short-circuit heating and burning of the battery, which will affect the normal driving of the vehicle and poor safety performance
