Abstract
The utility model discloses a kind of pcb board fixed structure, comprise metal shell, shell fragment and pcb board, inside metal shell, be provided with elastic mounts; In metal shell, the both sides of elastic mounts are symmetrically arranged with bracing frame; Bottom metal shell, rear end is provided with the convex closure of tapping; Shell fragment is articulated on metal shell by elastic mounts, and pcb board is fixed in metal shell by bracing frame, convex closure and shell fragment.The utility model shell fragment is articulated in coordinate on the bracing frame in metal shell and with convex closure and is stably fixed in metal shell by pcb board, do paving Copper treatment at the bullet tongue touching position of pcb board upper surface and shell fragment, ensure the electrostatic conducting realizing playing tongue and pcb board under the prerequisite that pcb board tightens up by bullet tongue.The utility model structure is simple, and installation and removal are convenient, do not use nut, pcb board can operations area large, easy to operate, thus improve the efficiency of pcb board welding, and then reduce production cost, alleviate the pollution level to environment, to the nothing harm of operator's health.
Description
Technical field
The utility model belongs to pcb board and installs technique for fixing field, particularly a kind of pcb board fixed structure.
Background technology
It is fastening that the support column of pcb board employing in the past adds screw and nut, should not carry out wrench operated at small space; Even welded nut, mustn't in spanner situation, welding is also to spend a large amount of electric power, affects environment, has certain injury to operator's health.In addition, general pcb board will do grounding, prevents components and parts electrostatic breakdown, structurally will do electrostatic conducting structure.
Utility model content
To be solved in the utility model to be that existing pcb board is fixing adopt support column to add screw-nut to tighten up, inconvenient operation, a large amount of electric power of welding cost, and contaminated environment produces injury to operator, and cost is high and the technical problem such as PCB electrostatic conducting.Thus provide a kind of easy to operate, the pcb board fixed structure that cost is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A kind of pcb board fixed structure, comprises metal shell, shell fragment and pcb board, is provided with elastic mounts inside metal shell; In metal shell, the both sides of elastic mounts are symmetrically arranged with bracing frame; Bottom metal shell, rear end is provided with the convex closure of tapping; Shell fragment is articulated on metal shell by elastic mounts, and pcb board is fixed in metal shell by bracing frame, convex closure and shell fragment.
Described shell fragment comprises elastic sheet body, and one end of elastic sheet body is provided with bullet tongue, and play tongue and play the effect compressing pcb board, the other end of elastic body is provided with L-type suspension member, and shell fragment is articulated in the elastic mounts of metal shell by suspension member.
Described suspension member is symmetrical about bullet tongue.
The lower end of described shell fragment main body is provided with supporting plate, and supporting plate and suspension member are positioned at same one end of elastic sheet body, and supporting plate matches with L-type suspension member, can effectively prevent coming off of shell fragment, makes shell fragment fix the better effects if of pcb board.
The height of described convex closure equals the height of bracing frame.
Described pcb board, being equipped with copper with shell fragment contact position, can realize the electrostatic conducting of shell fragment and pcb board.
The utility model shell fragment is articulated in coordinate on the bracing frame in metal shell and with convex closure and is stably fixed in metal shell by pcb board, the lower surface of pcb board is supported by bracing frame and convex closure, pcb board upper surface is compressed by the bullet tongue of shell fragment, do paving Copper treatment at the bullet tongue touching position of pcb board upper surface and shell fragment, ensure the electrostatic conducting realizing playing tongue and pcb board under the prerequisite that pcb board tightens up by bullet tongue.In convex closure position, pcb board is fixed by screws on convex closure.The utility model structure is simple, and installation and removal are convenient, do not use nut, pcb board can operations area large, easy to operate, thus improve the efficiency of pcb board welding, and then reduce production cost, alleviate the pollution level to environment, to the nothing harm of operator's health.
