[0002] Currently, automobiles commonly use PCB-structured electrical boxes to protect circuits and electrical appliances, while also distributing power. These boxes typically contain relays and fuses, and then transmit signals and current through connectors.

[0003] A typical electrical box connects to the vehicle's circuitry via a connector, serving only the functions of circuit protection and power distribution. Meanwhile, the main assembly is snapped onto the lower cover, which is connected to and secured to the vehicle body. The main assembly often fails to secure itself to the vehicle body, and the connection stability of the electrical box depends solely on the connection between the lower cover and the vehicle body, resulting in relatively low connection stability.
