Circuit board of automobile electric appliance centralized distribution box

Abstract

The invention relates to the technical field of automobile circuit application, and discloses a circuit board of an automobile electric appliance centralized distribution box, the circuit board comprises a distribution box body and a circuit board fixing device, the distribution box body is internally and symmetrically provided with strip-shaped fixing blocks, a mounting piece is clamped between the two strip-shaped fixing blocks, temperature sensing pieces are symmetrically arranged at the two ends of the mounting piece, a temperature conducting device is arranged between the two temperature sensing pieces and fixedly connected to one end of the metal connecting piece, and under the action of pressure, the first movable connecting rod extends outwards, and meanwhile, the second movable connecting rod is pressed downwards; and when the first movable connecting rod moves downwards and the angle of the connecting position is larger than 180 degrees, the two ends of the second movable connecting rod move upwards under the action of the supporting spring, meanwhile, the clamping piece is driven to move towards the inner side, the circuit board is fixedly clamped, and therefore the effect of conveniently and rapidly fixing the circuit board is achieved.

Description

technical field [0001] The invention relates to the technical field of automotive circuit applications, in particular to a circuit board of a centralized power distribution box for automotive electrical appliances. Background technique [0002] Automobile, that is, a vehicle that can be driven by its own power and does not need to be erected on rails or electricity. In a broad sense, a vehicle that is driven by its own mechanical energy is generally called an automobile. Because the automobile is loaded with many electronic instruments, Therefore, the power distribution box is required to arrange and install the circuit in the car. When the car is running for a long time, the temperature inside the circuit box is easy to rise. When the road is bumpy, the inside of the car will be bumpy at the same time, which will easily disconnect the lines connected to the circuit board inside the power distribution box, and the traditional way of fixing the circuit board is to use screws ...
