battery terminal

Abstract

The invention discloses a storage battery connection terminal, which comprises a welding plate, a lock groove block and a screw. The welding plate is in the shape of a "ji", the lock groove block is in the shape of a "mouth", and the right end of the welding plate is located in the lock groove On the upper surface inside the "mouth" of the block, the top of the lock groove block is provided with a threaded hole, and the screw passes through the threaded hole and is pressed on the upper surface of the right end of the welding plate, and the lower surface of the right end of the welding plate is provided with A toothed boss, the upper surface of the bottom of the "mouth" of the lock groove block is provided with a toothed boss, the left end of the welding plate is provided with a welding hole connected to the pole, and the left and right sides of the welding hole are provided with There are two gaps, the left end of the welding plate is provided with a semicircular protrusion, the thickness of the welding plate is 0.5-5mm, the wall thickness of the lock groove block is 2-5mm, and the upper end of the screw is provided with Inner hexagon, place the external wire in the hole of the lock slot block, press the right end of the welding plate and the lock slot block by rotating the screw, and then the external wire can be fixed. The connection between the terminal and the external wire is not easy to loose and generate heat, ensuring the quality of the battery .

Description

technical field [0001] The invention relates to a battery, in particular to a battery terminal. Background technique [0002] It has been 150 years since the creation of lead-acid batteries, and the application fields of batteries are very wide. At present, the charging and discharging current of the power battery is large, and the terminals of the battery are mostly made of metal materials. In order to facilitate the connection of external wires, the terminals need to protrude a part of the battery cover. The installation space of the car also limits the volume specific energy of the battery, and the exposed terminals are easy to contact with the outside metal, resulting in a short circuit. It is easy to loosen and generate heat, which hides potential risks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a storage battery terminal, which can effectively avoid the problem of loosening and heating at the connec...
