Description

Novel circuit board clamping plate

[ technical field ] A method for producing a semiconductor device

The utility model relates to a printed circuit board field especially relates to a novel circuit board splint.

[ background of the invention ]

The PCB, the name of which is printed circuit board, is also called printed circuit board, is an important electronic component, is a support of the electronic component, is a carrier for electrical connection of the electronic component, and the printed circuit board develops from single layer to double-sided, multi-layer and flexible, and still keeps respective development trend.

However, when the PCB inspection clamp in the prior art inspects and maintains the PCB, the thickness of some PCBs is large, the PCBs cannot be clamped through the grooves, the PCB inspection clamp is easy to shake in the inspection and maintenance process, and the inspection and maintenance of the PCBs are affected.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming above-mentioned prior art's shortcoming, providing a novel circuit board splint, can satisfy not unidimensional circuit board maintenance centre gripping.

The utility model discloses can realize through following technical scheme:

the utility model discloses a novel circuit board clamping plate, which comprises a bottom plate, a plurality of slide rails are transversely fixed on the front and back sides of the upper end surface of the bottom plate, a slide block connected with the slide rails in a sliding way is fixed on each slide rail, a fixed block is fixed on each slide block, a fixed bolt connected with the fixed block in a threaded way is fixed on each fixed block, a limit block is fixed on the upper end surface of each slide block, slide bars are transversely fixed on the left and right sides of the upper end surface of the bottom plate, a plurality of connecting blocks are uniformly fixed on the slide bars, two connecting blocks at corresponding positions on the slide bars are mutually fixed through supporting bars, supporting blocks through which the supporting bars pass and are connected with the supporting bars in a sliding way are also fixed on the supporting bars, the supporting blocks are connected with the connecting blocks at the right side through springs, the supporting bars pass through the springs at, the lower end face of the positioning block is obliquely arranged. When a circuit board is clamped, the position of a sliding block on a sliding rail is adjusted, so that the distance between limiting blocks at the front side and the rear side meets the width when the circuit board is placed, a supporting block is pulled to move on a supporting rod, the supporting block extrudes a spring and moves through a sliding connecting block to avoid the maintenance position of the circuit board, a supporting bolt is rotated, the supporting bolt is in threaded connection with a threaded sleeve, the supporting bolt is extruded after contacting with the sliding rod after descending, the supporting rod is fixed, the circuit board is placed on the upper end surfaces of two supporting rods, the front side and the rear side of the circuit board are in contact with the limiting blocks at the two ends, the left end of the circuit board is abutted against the connecting block at the left side, the supporting block is loosened, the spring returns to a natural state, the supporting block is pushed to move by the spring, a positioning block is fixed, the locating block moves to and extrudes the upper end face of the circuit board after contacting with the circuit board, the circuit board is fixed, after the circuit board is fixed, the position of the sliding block is adjusted, the limiting block is enabled to be abutted against the circuit board, then the fixing bolt is rotated, and after the fixing bolt descends, the sliding block is fixed by being extruded with the bottom plate, so that the circuit board is completely fixed.

Compared with the prior art, the utility model has the advantages that:

when the circuit board overhauls, fixed the circuit board all around through this device, it is unable fixed through the recess to avoid the circuit board that thickness is thicker, leads to the problem of unable maintenance to take place to thereby can satisfy not unidimensional circuit board fixed demand through the position between the adjustment slider.
