A large current pole assembly with error prevention function for a battery pack

Abstract

The invention discloses a large current pole assembly with error prevention function for a battery pack, comprising a fastening cap, a protective cover, a stopper, a pole, a flange seat, a mounting ring, a conductive nut, a conductive washer, a countersunk screw and a countersunk screw. Generally speaking, the output of positive and negative poles of many batteries is realized by stud, which is simple, but it is easy to cause reverse short circuit and damage of batteries or equipments, and constitutes a potential safety hazard. Therefore, measures should be taken to prevent pole connection errors. The pole designed by the invention has a disk, the disk protrudes from both sides of the boss, the screw pole is protruded from the boss, and the external conductive terminal is fixed to the bossplane by a nut to realize plane conductive function. Compared with the threaded conductive mode of the common pole, the provided pole assembly has smaller contact resistance, and therefore has the capability of excessive current.

Description

technical field [0001] The invention belongs to the field of pole components for battery packs, in particular to a high-current pole component for battery packs with the function of error prevention. Background technique [0002] Battery packs used in launch vehicles, directed energy and other equipment generally require high current requirements, especially in special occasions such as electromagnetic ejection, laser power supply, and electric servo. Since there is no suitable electrical connector for high-current power supply battery packs, studs are generally used for external connection and power supply. However, the positive and negative poles of high-current power supply battery packs currently use the same stud structure, which does not have the function of error prevention. Often during the wiring process, the lines are reversed or misconnected, resulting in damage to the battery or equipment, and even safety accidents. In addition, the currently commonly used high-...
