Abstract

The invention discloses a BCM electrical box, which comprises a bottom-to-top wiring bottom case, a metal access panel, a fuse detection circuit board, and a component bearing board; wherein, the wiring bottom case is detachably connected to the component bearing plate , so as to form a seal on the metal access panel and the fuse detection circuit board; the component carrier plate 4 is used for installing components such as relays and fuses. The invention has the characteristics of reasonable structure, low cost, high pressure resistance, large load and the like.

Description

technical field [0001] The present invention relates to an automobile safety device, more specifically, it relates to a BCM electrical box. Background technique [0002] The rapid development of electric vehicles has gradually become one of the important development directions of future automobiles. The high-voltage circuit of an electric vehicle is a circuit composed of high voltage, DC, fuse, load, and negative ground. When a short circuit occurs in the circuit, in order to avoid burning out the wiring harness and electrical equipment, a safety device is added to the circuit. Therefore, when a short circuit occurs in a certain line, the fuse will be blown first, and the electric vehicle will lose a certain function due to the short circuit and cannot be used normally. As the core of the power distribution system, the DC power distribution box adopts an integrated method and has the functions of branching and protection, which reduces the space requirements for the layout...
