High-current quick connection adapter used in box body

Abstract

The invention discloses a high-current quick connection adapter used in a box body. The high-current quick connection adapter comprises a connecting copper sheet, multiple layers of flexible copper sheets, a base connecting pin and a bilateral pluggable base, wherein the bilateral pluggable base is fixed on the box body, one side is connected with a plug with a cable outside the box body, and theother side is connected with the base connecting pin; the base connecting pin is located inside the box body; the base connecting pin is fixedly connected with the connecting copper sheet through multiple layers of flexible copper sheets, the multiple layers of flexible copper sheets are formed by stacking two or more layers of flexible copper sheets, and the outer surfaces of the multiple layersof flexible copper sheets are wrapped with insulating layers; and the connecting copper sheet is connected with a circuit in the box body. The device is simple in structure, convenient to disassembleand assemble, capable of saving space and reliable in connection.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a high-current fast connection adapter used inside a box body. Background technique [0002] The application of electric energy has been very extensive, especially in the fields of electric vehicles, electric aircraft, electric ships, etc. At present, electric energy storage devices, electric energy management devices, various electrical equipment, etc. are all packaged in a small box Inside the space, the boxes are connected by cables. The electrical connector base is installed on the box, and the external electrical connector plug is connected to the external cable. The base goes deep into the box, and then connects with the internal circuit of the box. At present, the structure where the base penetrates into the inside of the box is generally a copper plate, or a solder cup used for welding cables. When the current is too large, the outer diameter of the cable t...

AI Technical Summary

Problems solved by technology

When the current is too large, the outer diameter of the cable that needs to be welded by the welding cup is larger, which brings difficulties to the welding, and it is not easy to disassemble after welding, resulting in inconvenient maintenance. In addition, the cable with a larger outer diameter is not easy to deform and takes up a large space. Unreliable; if the internal base structure of the box is a copper plate, the base can be connected to the internal circuit through a special-shaped copper plate, and the special-shaped copper plate and the box base are connected by bolt compression, but the bolts may be loose, and the bolt connection also has disassembly The problem is that the required installation space is large, and the weight of the connecting bolts is additionally increased
