Description

Technical Field

[0001] This utility model relates to an electrical box module and an electrical box including the electrical box module. More particularly, this utility model relates to an automotive central electrical box applicable to passenger cars and commercial vehicles. Background Technology

[0002] In existing technology, the automotive central electrical box is a crucial component of the automotive electrical system. Its function is to distribute power to all vehicle electrical equipment, provide circuit protection, and also possess certain logic control functions. There are two existing types of automotive electrical boxes. One type includes a box body and an integrated circuit board mounted within the box, on which components such as busbars, pins, surface-mount resistors, diodes, and relays are mounted. The other type includes a box body and two integrated circuit boards mounted within the box, each equipped with components such as busbars, pins, surface-mount resistors, diodes, and relays. However, in existing electrical boxes, all current still needs to pass through the circuit board, resulting in a high load and large size for the circuit board. When the number of components inside the electrical box is reduced, the size of the circuit board cannot be reduced accordingly because the circuit board size is fixed. Fuse terminals also need to be output through the circuit board, leading to an excessive number of connection terminals on the circuit board. Utility Model Content
