Safety PCB

Abstract

The invention relates to a safety PCB which comprises a circuit wire layer (1), an insulating layer (2), a heat conducting layer (3) and a substrate (4). The circuit wire layer (1), the insulating layer (2), the heat conducting layer (3) and the substrate (4) are sequentially arranged from top to bottom. The circuit wire layer (1) comprises a circuit wire (5) and an external power source connection wire (6). The external power source connection wire (6) comprises an external connection section (7) and a bent elastic conducting strip (8). Plastic rubber is adopted for connecting the circuit wire (5) with the external power source connection wire (6) in the circuit wire layer (1) through the bent elastic conducting strip (8). A heat conducting rod (10) is designed to feed back the temperature of the heat conducting layer (3) to the plastic rubber in real time. The real-time monitoring effect is achieved through a pure physical structure, it is ensured that power supplied by the external power source to the PCB can be turned off in time in emergency, and whole work safety is ensured.

Description

technical field [0001] The invention relates to a safety PCB board. Background technique [0002] PCB board is printed circuit board, also known as printed circuit board, printed circuit board, circuit board for short, with insulating board as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes (such as component Holes, fastening holes, metallized holes, etc.), used to replace the chassis of electronic components installed in the past, and realize the interconnection between electronic components. Because this kind of board is made by electronic printing, it is called "printed" circuit board; according to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. They are not the same, so...

AI Technical Summary

Problems solved by technology

Since the surface of the PCB board is equipped with electronic components in practical application work, the electronic components on the PCB board will generate heat in actual work. Since each electronic component is closely attached to the surface of the PCB board through solder, the heat generated by each electronic component will be directly Pass it to the PCB board. The existing PCB boards have been improved for this situation. For example, the structure of the PCB board is improved to discharge the heat. Function, but the effect is not so obvious, and with the increase of use time, the heat dissipation effect of the structure will become worse and worse, if the temperature is too high, it is easy to cause safety accidents, burn electronic components and PCB board
