Problems solved by technology

Copper bars carry out current transmission. Since each copper bar has to be molded, the product development time is long and the investment cost is high, and the copper bars are staggered, resulting in cumbersome wiring and bulky electrical modules, which take up a lot of space. Since the copper bars are connected by screws, it is easy to cause the loosening of the copper bars, resulting in high-voltage leakage, which cannot meet the requirements of beautiful wiring, high reliability, and safety in construction machinery; the single PCB circuit board solution is due to large current and small The current flows together, the wiring design is difficult, and the final product size will be large

Abstract

The invention relates to a multilayer PCB (Printed Circuit Board) central distribution box. The multilayer PCB central distribution box comprises an insulated box body, a plurality of PCBs positioned inside the insulated box body and at least one pair of conductive pins; the plurality of PCBs are arranged in parallel and layer by layer, and the two adjacent layers of PCBs are insulated by insulating paper and connected by insulating screws; one end of each of the two conductive pins in every pair of conductive pins is connected to the different layer of PCB, and the other end extends out from the outermost PCB. A common PCB design in weak current is introduced to the multilayer PCB central distribution box, and the plurality of PCBs are applied to high-current wiring, so that high tidiness, high safety, high safety and minimum cost of wiring are achieved.

Description

technical field [0001] The invention belongs to the electrical field of construction machinery, and in particular relates to large-current control by adopting multilayer PCB line energization technology, and in particular relates to a multilayer PCB central distribution box Background technique [0002] In the field of construction machinery at this stage, the electrical aspect must encounter a large current of up to 30A. A large part of the high-current electrical control uses copper bars for current transmission or a single PCB circuit board solution. Copper bars carry out current transmission. Since each copper bar has to be molded, the product development time is long and the investment cost is high, and the copper bars are staggered, resulting in cumbersome wiring and bulky electrical modules, which take up a lot of space. Since the copper bars are connected by screws, it is easy to cause the loosening of the copper bars, resulting in high-voltage leakage, which cannot ...
