Abstract

The invention discloses a high-current pole component with error-proof function for a battery pack, which includes a fastening cap, a protective cover, a limit piece, a pole, a flange seat, a mounting ring, a conductive nut, a conductive washer, and a countersunk head Screw one, countersunk screw two. In general, the positive and negative poles of many battery packs use studs to realize external output. This method is simple, but it is prone to reverse short circuit phenomenon, causing damage to the battery pack or equipment, and posing a safety hazard. Therefore, measures need to be taken to prevent pole connection errors. There is a disc on the pole designed by the present invention, and the disc protrudes from both sides of the boss, and the stud is protruded from the boss, and the external conductive terminal is fixed to the plane of the boss through the nut to realize the plane conduction function, which is different from the ordinary pole. Compared with the threaded conductive method of the post, it has a smaller contact resistance, so it has the ability to over-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-...
