Positive-electrode joint fuse box and assembly for automobile storage battery

Abstract

The invention provides a positive-electrode joint fuse box and an assembly for an automobile storage battery. The positive-electrode joint fuse box comprises a box body, a box cover and a communication sheet. The communication sheet is composed of a large current connection part, a small current connection part, a fixed part and a connection part. The large current connection part and the small current connection part are respectively provided with a large connecting hole and a small connecting hole. The box body comprises a large current wire harness connecting column, two rows of small current wire harness connecting columns and a fuse installation slot. The large current wire harness connecting column and the small current wire harness connecting columns are separated. The large connecting hole is matched with the large current wire harness connecting column. The small connecting hole is matched with one row of small current wire harness connecting columns. According to the technical scheme of the invention, the large current wire harness connecting column and the small current wire harness connecting columns are separated on the box body. Meanwhile, the current of the positive-electrode joint of a storage battery is led to each connecting column by the communication sheet. Therefore, the phenomenon that the heat is excessively large in the local region caused by the concentration of the large current can be avoided.

Description

technical field [0001] The invention relates to the field of connection of automobile storage batteries, in particular to a fuse box and an assembly for the positive pole connector of automobile storage batteries. Background technique [0002] The electric energy of the electrical components of the automobile comes from the battery and the generator, and is transmitted to each electrical component through the vehicle wiring harness. overload protection. [0003] The car battery positive terminal fuse box is the most common type of central electrical box. Such as figure 1 As shown, the existing automobile battery positive terminal fuse box includes a box main body 1' and a box cover 2', wherein a plurality of fuse slots 11' arranged in parallel are arranged in the box main body 1', and the box cover 2' is used to close the box In the main body 1', one end of the fuse provided in the fuse slot 11' is connected to the positive terminal of the battery, and the other end is co...

AI Technical Summary

Problems solved by technology

[0004] The fuse slots 11' of the fuse box of the positive terminal of the automobile battery with this structure are arranged in parallel. The fuse locally generates a large amount of heat at the connection point with the vehicle wiring harness, which adversely affects the heat dissipation of the fuse box at the positive terminal of the vehicle battery and thus affects the safety of the vehicle
