Circuit board with safety protection function

Abstract

The invention discloses a circuit board with a safety protection function. The circuit board comprises a protection box, and a circuit board frame is arranged in the protection box; a circuit board body is arranged on the circuit board frame; a heat dissipation mechanism is arranged in the protection box and located under the circuit board frame. A wiring board is arranged right above the circuitboard frame in the protection box; the circuit board body is fixed on the circuit board frame; and leads connected to the circuit board body are respectively clamped on wiring blocks on the bottom surface of the wiring board. The lead is clamped through the elastic clamping frame on the wiring block; relative fixation between the circuit board body and the lead is realized. When the circuit boardbody vibrates or collides in the use process, the circuit board body and the lead are always kept in relative positions, so that the phenomenon that the circuit board body and the lead are disconnected due to vibration can be effectively avoided, the use safety performance of the circuit board body is greatly improved, and the safety protection function of the circuit board body is improved.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a circuit board with a safety protection function. Background technique [0002] The circuit board is a miniaturized and intuitive circuit, which plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. Generally used circuit boards use conductive materials as the substrate, and there are fixed plates on both sides of the substrate. The gold holes and the solder feet make the electrical connection between the fixing plate and the substrate, so that the corresponding electronic devices are fixed on one side of the fixing plate, and the other side of the fixing plate is used to connect the circuit. [0003] For example, the patent application number (CN201920242235.X) discloses a multifunctional protective circuit board, including a board body, a fixing box is arranged on the outside of the board body, and ...

AI Technical Summary

Problems solved by technology

[0004] 1. During the use of the existing circuit boards, usually the circuit board rack can only realize the installation of circuit boards of a certain size, which has great limitations;

[0005] 2. During the use of the existing circuit board in the vibration equipment, the solder joints may loosen or fall off due to the vibration, and the wires on the circuit board body may be separated from the circuit board due to accidental pulling. , which in turn will cause the printed circuit board to malfunction, thereby affecting the normal use of the printed circuit board;

[0006] 3. The use of the existing circuit board will directly expose the circuit board body to the air, which is easy to contaminate the surface of the circuit board with dust, and the electronic devices will generate heat during the working process of the circuit board, and the heat will stay on the circuit board body for a long time. reduce the lifetime of the circuit board
