Currently, the closest prior art in the industry is: in the design of electronic products, due to the factors of limited structural space, the single chip microcomputer is easily interfered by a power circuit, an analog circuit is easily interfered by a digital circuit, heat dissipation problems and the like, the PCB needs to be designed in a modularized manner, so that the problem is how to connect a plurality of PCBs? How the top laminate is fixed? The top plate and the bottom plate of the electronic product on the market at present are connected by a lead, the pins of the electronic component are connected, and the electronic component is connected with a special connecting pin, double-sided adhesive tape, silicon rubber and the like. When the wires are connected, the upper plate cannot be accurately positioned and needs to be additionally fixed, so that the product cost is increased, and the assembly process is increased; when pins of electronic components are connected, the pins are easily subjected to horizontal direction position deviation and vertical direction unevenness in manual welding, repeated adjustment is needed by welding personnel, the production efficiency is influenced, and even a welding tool is needed to be manufactured to guarantee the welding positioning problem; special connecting pins are used for manual welding, and the situation of connecting pins of electronic components is also caused; the double-sided adhesive tape is bonded, so that accurate positioning cannot be achieved, if the button is operated, the position of the PCB can deviate, the double-sided adhesive tape can fall off after a user uses the double-sided adhesive tape for a long time, and the after-sale cost of an enterprise is increased; silicon rubber can not accurately position the PCB, increases the assembly difficulty, and needs to be cleaned when in maintenance, thereby influencing the fault speed of field treatment.

In summary, the problems of the prior art are as follows:

(1) the existing PCB connecting mode can not accurately position the PCB, and the PCB needs to be additionally fixed, so that the assembly difficulty is increased, and the production efficiency is influenced.

(2) The PCB board is easy to fall off after being fixed by double faced adhesive tape, thereby increasing the maintenance difficulty and influencing the fault speed of field treatment.

The difficulty of solving the technical problems is as follows: the PCB design engineer is required to have professional hardware design knowledge and richer design experience, the positioning of the bottom PCB and the positioning of the fixing holes of the bottom PCB are both required to be accurately positioned, and the top plate and the bottom plate are concentric to ensure the accurate positioning of the top plate. In addition, the type selection of the connector is very important, otherwise, the top plate and the bottom plate are connected and loosened, poor contact is easy to occur, and the product quality is seriously influenced.

The significance of solving the technical problems is as follows: the PCB is accurate in positioning, the circuit is neat and attractive, the product performance is stable, batch processing is easy, interference caused by too many circuit connecting lines is avoided, and the PCB is convenient to assemble and maintain.
