Abstract
The utility model discloses a quick fixing structure for a PCB (Printed Circuit Board) of an automotive audio. The quick fixing structure comprises the PCB and a middle frame of the automotive audio, wherein mounting holes and bulges are arranged on the PCB, supports and supporting holes are arranged on the middle frame of the automotive audio, a fastener and a supporting surface are arranged on either support, the bulges on the PCB are matched with the supporting holes on the middle frame of the automotive audio in a clamped manner, the mounting holes on the PCB is fixed with the supports in a matched manner, and the supports are arranged on the middle frame of the automotive audio and are provided with the fasteners and the supporting frames. In the utility model, as screws and the processing of threaded holes are eliminated, the whole cost of the automotive audio is reduced; as the fastener design is adopted on the support, a locking surface of the fastener is of the design of a self-locked slope, and the PCB can be locked by only rotating the fastener at a small angle, so that the production process is simplified, the processing is convenient, and production efficiency is improved; the quick fixing structure can satisfy the function of quickly fixing the PCB, can be disassembled conveniently and quickly and is convenient to repair a circuit on the PCB and replace elements and components.
Description
Technical field:
The utility model relates to the motor vehicle component device, relates in particular to the quick fixed structure of a kind of automobile audio pcb board, belongs to the electronic product field.
Background technology:
At present, known in the automobile audio production industry, a main PCB plate is arranged in the automobile audio, be furnished with the components and parts of circuit and numerous welding on the pcb board, to realize the automobile audio function, in order to guarantee each components and parts steady operation, pcb board needs fixed.
At present, in the automobile audio product, the fixing employing mostly of pcb board is threaded fixing.Mode is: on the automobile audio center, stretch out boss; Thread mill drilling on boss is reserved the screw via hole, in the time of fixedly on the pcb board; Pcb board is placed on by the tram on the boss that stretches out on the automobile audio center, with screw pcb board is anchored on the automobile audio center again.This fixed form comes with some shortcomings: at first; Need on the automobile audio center to make boss, on boss, reprocess screwed hole, increased difficulty of processing; If when thread mill drilling, cause stripped thread in addition, grind one's teeth; Then whole automobile audio center just becomes waste product, can not re-use, and causes processing cost to increase.The second, in automobile audio manufacturing process, can run into defective products unavoidably; Need the dismounting pcb board to keep in repair, the screw of dismounting can not be reused again, in the process of dismounting, can cause the screwed hole stripped thread in addition; The automobile audio center just becomes waste product, can not re-use, and causes cost to increase.
Summary of the invention:
The purpose of the utility model just provides a kind of quick fixed structure of automobile audio pcb board simple and reliable for structure.
The technical scheme that the utility model adopts is:
The quick fixed structure of a kind of automobile audio pcb board comprises pcb board, the automobile audio center: have a pcb board, said pcb board is provided with installing hole and convexity, and the automobile audio center is provided with supporting and support holes, and supporting is provided with buckle and bearing-surface; Convexity on the said pcb board clamps with the support holes of automobile audio center and cooperates, the supporting matching and fixing that has buckle and bearing-surface on installing hole on the pcb board and the automobile audio center.
Said pcb board and automobile audio center are fixed through the supporting, support holes, the protruding realization that have buckle and bearing-surface fast.
Said pcb board is provided with installing hole and convexity.
The automobile audio center is provided with supporting and support holes, and supporting is provided with buckle and bearing-surface.
The locking face of the buckle in the said supporting is the self-locking inclined-plane.
The both sides mating surface of the convexity on the said pcb board is the inclined-plane.
Compared with prior art, the beneficial effect of the utility model is:
The utility model has omitted screw fixation method, has saved hole processing and screw, has reduced the whole cost of automobile audio; Adopt the buckle design in the supporting, the locking face of buckle is inclined-plane self-locking design, and low-angle reverses can lock pcb board, has simplified production technology, easy to process, has improved production efficiency; This structure can not only satisfy fast the fixedly function of pcb board, and can fast easily quick-detach, is convenient to keep in repair circuit, replacing components and parts on the pcb board.
