Central power distribution box for vehicle

Abstract

The invention discloses a central power distribution box for a vehicle. The central power distribution box comprises a base and an upper cover, wherein the four corners of the base are provided with threaded holes, and the four corners of the upper cover are provided with mounting holes that match with the threaded holes. The base and the upper cover are connected through bolts, at least four wiregrooves are provided side by side inside the base, and two inlet wire grooves which are perpendicular to the wire grooves are provided beside the wire grooves. Inlet wire binding posts inside the communicating inlet wire grooves and wire grooves are electrically connected with middle binding posts by bus bars. A power supply binding post is provided between the middle binding post and an outlet wire hole of every wire groove, and the middle binding post and the power supply binding post in the same wire groove are electrically connected through a fuse. According to the central power distribution box for a vehicle, most electrical circuit system of a heavy truck can be controlled by the central power distribution box (complete vehicle primary power distribution box), the fuses and wire collectors are integrated in the central power distribution box, so as to group the distributed electrical circuits together, the complete vehicle manufacturing and electrical circuit maintenance are easily performed, the sealing effect of the power distribution box is good, and the working stability of components is improved.

Description

technical field [0001] The invention relates to the field of automotive electronic equipment, in particular to a power distribution box. Background technique [0002] With the development of automobiles, more and more electrical devices are needed in automobiles. Most of the original devices are directly connected to the battery through wires. However, due to the harsh environment of the wires, it is easy to cause damage or even breakage of the wires. At present, most of them use power distribution. The boxes are uniformly connected to electricity, but there are still problems such as confusing wiring harness connections and poor sealing effects. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a power distribution box structure that can improve the working stability of the automobile electrical system and facilitate later maintenance and repair. [0004] In order to achieve the above object, the technical soluti...
