SMD (Surface Mounting Device) nut and circuit board assembly

Abstract

The invention relates to the technical field of power equipment and discloses an SMD (Surface Mounting Device) nut and a circuit board assembly. The circuit board assembly comprises a circuit board, wherein guide rails are fixedly mounted at the top end and the bottom end of the circuit board; first slide grooves are formed in the front sides of the two guide rails; plug boards are fixedly mountedat the left and right sides of the circuit board; slide blocks are movably connected to the front sides of the first slide grooves; movable frames are fixedly mounted at one sides of the slide blocksaway from the circuit board; and second slide grooves are formed in opposite sides of the inner walls of the movable frames. The SMD nut and the circuit board assembly have the advantages that the guide rails are arranged, the first slide grooves are formed in the front sides of the guide rails, the slide blocks can move on the inner walls of the slide grooves by the arrangement of the first slide grooves to enable the movable frames to move, the positions of clamping boards can be changed by moving the slide blocks, and then, the circuit board can be clamped with clamping bases in differentpositions, so that the mounting range of the same circuit board is wider, and the circuit board can be mounted more conveniently by a user.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a patch nut and a circuit board assembly. Background technique [0002] The names of circuit boards include ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin Circuit boards and printed (copper etching technology) circuit boards, etc., circuit boards make circuits miniaturized and intuitive, and play an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards can be called printed circuit boards or printed circuits Board, the English name is PCB and FPC circuit board (FPC circuit board is also called flexible circuit board. Flexible circuit board is a kind of highly reliable, excellent flexible circuit board ma...
