Technical field

The present invention relates to printed circuit board mounting technique field, especially a kind of buffer structure of printed circuit board.

Background technique

The fixed form of currently used electronic circuit board structure mainly fixes pcb board in such a way that screw locks On rigid bracket and/or shell, if there is the case where falling or colliding, shaking impact force occurred can be by screw, branch Frame and/or shell pass to pcb board, lead to pcb board component wear or fall and continue to use electronic product can not.

Summary of the invention

It is an object of the invention at least solve one of the technical problems existing in the prior art, a kind of printed circuit is provided The buffer structure of plate solves the problems, such as that pcb board is damaged because falling or colliding.

Further, the both ends of the bracket are additionally provided with protrusion used for positioning, the both ends of the pcb board be equipped with it is described convex The recess portion that portion matches.

Further, the protrusion is an arc convex body, and the recess portion is an arc groove, and the recess portion front end is from the protrusion Front end slid into along the outer of the protrusion, until the protrusion is embedded in the recess portion, keep the bracket and the pcb board solid Fixed connection.

Further, at least two positioning columns are provided on the groove, the bracket is equipped with and the positioning column phase The location hole matched.

It further, further include flexible couplings and screw, the bracket is equipped with threaded block, and the shell is equipped with first Fixation hole, one end of the flexible couplings are connect with the pcb board, and the other end of the flexible couplings is equipped with and the spiral shell The second fixation hole that line seat matches, the screw sequentially pass through after first fixation hole and second fixation hole with it is described Threaded block is threadedly coupled.

Further, the flexible couplings be FPC plate, the FPC plate by way of welding or being bonded with the pcb board It is fixedly connected and is electrically connected with the pcb board.

Further, the threaded block, first clamping portion and the bracket are an integral molding structure.

It further, further include lock sheet, the lock sheet is equipped with third fixation hole, and the screw sequentially passes through described the It is threadedly coupled after one fixation hole, the third fixation hole and second fixation hole with the threaded block, makes the shell, institute It states flexible couplings and the bracket lock is tightly connected.

Further, the shell includes the upper housing being mutually fastened and connected and lower case, and the flexible couplings include the One flexible couplings and the second flexible couplings, the screw include screwing and lower screw, and the threaded block includes being set to institute The upper threaded block in pedestal upper end face and the lower threaded block set on the pedestal lower end face are stated, the screwing sequentially passes through described Upper housing and first flexible couplings are threadedly coupled with the upper threaded block, and the lower screw sequentially passes through the lower case It is threadedly coupled with second flexible couplings with the lower threaded block.

The utility model has the advantages that using the knot of the bracket of flexible material, the structure of bracket insertion groove and bracket and pcb board clamping Structure can avoid making to be screwed pcb board, to play the role of buffering when falling or colliding, be effectively prevented from shake The raw energy transmission of movable property is to bad situation produced after pcb board；

In addition, realizing the fixation between pcb board and shell using flexible couplings, the transmitting effect of vibration is also further decreased Rate is effectively protected pcb board.
