Problems solved by technology

[0003] Among them, the disadvantage of the first method is that the welding method is likely to cause secondary high-temperature desoldering risks to the components that have been soldered on the two PCB boards separately, and there are hidden quality problems; there are solder joints between the two PCB boards, resulting in The two PCB boards cannot be bonded together, resulting in poor heat conduction between the two PCB boards, heat cannot be quickly released by one of the PCB boards, and the heat accumulated in the air between the two PCB boards cannot be released. Poor stability; when the product needs to be reworked, it is difficult to disassemble
The disadvantage of the second method is that the product is not conducive to automatic assembly; the pressure perpendicular to the board surface needs to be applied between the two PCB boards to ensure the elastic contact between the shrapnel and the point to be conducted, and the structure is more complicated; and the two PCB boards There is a large gap between the PCB boards, and the heat dissipation is poor

Abstract

The invention relates to a PCB (Printed Circuit Board) electrical connection assembly. The PCB electrical connection assembly comprises a first PCB and a second PCB; the first PCB and the second PCB are each provided with a through hole penetrating along the thickness direction, and the hole wall of each through hole is provided with a conductive layer; and the PCB electrical connection assembly further comprises conductors arranged in the through holes of the two PCBs in a penetrating mode, and the conductors make conductive contact with the conductive layers of the through holes so that circuit conduction of the two PCBs can be achieved. Compared with a welding mode in the prior art, secondary high-temperature desoldering risks do not exist, potential quality hazards are eliminated, the two PCBs can be attached together, the heat dissipation effect is better, and in addition, when a product needs to be reworked, disassembly is convenient. Compared with an elastic sheet press-fitting mode in the prior art, excessive pressing force does not need to be applied to the two PCBs, automatic assembly is facilitated, the two PCBs can be attached together, and the heat dissipation effect is better.

Description

Technical field [0001] The present invention relates to a PCB plate electrical connection assembly. Background technique [0002] During the assembly of the electrical component, sometimes two PCB boards are turned on, and there are two ways to have: the first way such as figure 1 As shown, the need to guide the first PCB plate 100 and the second PCB plate 200 is welded together to form the weld body 300, and the circuit conduction is achieved by the weld body 300. Second way figure 2 As shown, both the lower end of the first PCB plate 100 and the upper end of the second PCB plate 200 need to conduct a conduction point, and the shrapnel 400 is pressed between the two needed points, and two by elastic deformation of the elastic sheet 400. The circuit conduction of the PCB board. [0003] Among them, the shortcoming of the first method is that the welding is easily soldered on two PCB boards that have been welded separately, and there is a mass hidden danger; there is a solder join...
