Abstract
The utility model provides a kind of heat conduction structure of circuit board, including the heat conduction plate being arranged on circuit board and the heat dissipation plate being arranged on heat conduction plate, the through hole is opened in the circuit board, the bottom surface of the heat conduction plate is fixedly connected with the plug block of several through hole settings, the side surface of the plug block is equipped with the receiving slot, the first lock block is movably connected in the receiving slot.The utility model has the advantages of: first lock block is pressed into receiving slot, and plug block is inserted into through hole, when first lock block completely passes through through hole, first spring pushes first lock block to move, first lock block is clamped on the bottom surface of circuit board, realize the constraint of heat conduction plate vertical, and heat conduction plate is locked. Pull out pull rod, pull rod drives second lock block to move into movable slot, and heat dissipation plate is buckled on heat conduction plate, and pull rod is loosened, second spring pushes second lock block to be clamped into lock hole, and the locking of heat dissipation plate is realized. Without the tedious screw dismounting work, installation is quick and convenient.
