Abstract

The invention provides a circuit board design method and the circuit board of an electric box for commercial vehicles, which are used to solve the technical problems of high cost and heavy weight existing in the circuit board of the electric box of an automobile. According to the different carrying currents of different pins of the relay, the present invention designs pads corresponding to different pins on the circuit board, and sets different socket terminals on the pads corresponding to different pins, wherein the relay carrying a larger current normally opens the load The terminal pins adopt box-type socket terminals, and the pins at the normally closed load end of the relay carrying a small current and the pins at the control end of the relay coil adopt tuning fork socket terminals. Finally, the box-type socket terminals and tuning fork socket terminals are connected in various forms. combination to form different types of relay packages. The invention not only ensures the electrical connection strength between the relay pin and the socket under the condition of high temperature and high vibration, but also saves the cost of components and the weight of the electrical box, and at the same time can reduce the solder paste required for circuit board welding and save the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of automobile electrical boxes, in particular to a circuit board design method and a circuit board of an electrical box for a commercial vehicle. Background technique [0002] At present, the competition in the entire automobile industry is becoming more and more fierce. Both automobile manufacturers and auto parts suppliers are facing increasing cost pressures. In order to survive, enterprises must find ways to reduce costs. As the main component of the car, the automotive electrical box also faces the problems of increasing costs and decreasing profits. As an important part of the automotive electrical box, the circuit board and the soldering terminals on the circuit board account for more than half of the cost of the entire electrical box, which determines the reduction. Circuit board cost is particularly important. At present, the electrical box used in automobiles, especially the electrical box used in...
