Abstract
The utility model discloses a PCB fixing device used for fixing a PCB. The PCB fixing device comprises an upper cover, a base, at least two upper fixing plates and at least two lower fixing plates, and at least two arc clamping parts, wherein the upper cover is snapped onto the base. The upper ends of the upper fixing plates are fixedly connected to the inner bottom surface of the upper cover. The lower ends of the upper fixing plates are abutted against the upper end surface of the PCB. The lower ends of the lower fixing plates are fixedly connected to the inner bottom surface of the base. The upper ends of the lower fixing plates are L-shaped to be snapped onto the lower end surface and the side surface of the PCB. The arc clamping parts are disposed on the inner side surface of the base. The technical effects are that the upper fixing plates disposed on the upper cover, and the lower fixing plates and the arc clamping parts disposed in the base are used for fixing the PCB. The PCB fixing device is advantaged by being simple in structure, low in cost and durable, and prevents problems that a screw causes a plastic housing to be worn or damaged in the previous usage and problems that glue is not helpful in heat radiation and easily falls off under the conditions of high and low temperature.
Description
Technical field
The utility model relates to pcb board fixture design field, relates in particular to a kind of fixture of the pcb board that is applied to wireless charger.
Background technology
Since in June, 2007, the Massachusetts Institute of Technology successfully realized wireless power transmission first, wireless charging technological development is risen rapidly.At present, adopt the wireless charger of wireless charging technology development to realize industrialization.Pcb board is one of core component of wireless charger, and its effect is particularly important.
The pcb board of conventional wireless charger often adopts screw or glue to fix, and all has certain defect.Adopt and be screwed pcb board and mainly contain 2 deficiencies: one, need punching and add screw, virtually increase the flow process of producing, reduce production efficiency; Its two, screw is generally metal, electric appliance casing is generally plastics, metal tends to plastics to cause wearing and tearing, causes in the course of time the loosening of screw and comes off.Adopt the fixing pcb board of glue also to mainly contain 2 deficiencies: one, glue easily comes off; Its two, glue be unfavorable for heat radiation, this is totally unfavorable to charger.
Utility model content
The utility model provides a kind of pcb board fixture, solves the problem that uses screw to cause wearing and tearing even to ftracture to plastic casing in pcb board fixture in the past, and uses glue to be unfavorable for heat radiation, under high low temperature, holds caducous problem.
For above-mentioned functions is provided, the utility model provides a kind of pcb board fixture, for fixing pcb board, comprises upper cover and the base of engaging, is also provided with at least two group upper mounted plates and bottom plate and at least two arc clamping parts;
Fixed plate upper end is fixedly connected on the inner bottom surface of described upper cover, and fixed plate lower end props up the upper surface of described pcb board,
Described bottom plate lower end is fixedly connected on the inner bottom surface of described base, and the upper end of described bottom plate is set to L shaped, blocks described pcb board lower surface and side,
Described arc clamping part is arranged on described base medial surface, and described arc clamping part blocks the side of described pcb board, is provided with the arc-shaped depression portion corresponding with described arc clamping part in the access section of the side of described pcb board.
The disclosed pcb board fixture of the utility model, by upper mounted plate being set at upper cover, bottom plate being set and arc clamping part fixes pcb board at base, there is simple in structure, with low cost, long-lived advantage, avoid the problem that in the past uses screw to cause wearing and tearing even to ftracture to plastic casing, and use glue to be unfavorable for dispelling the heat, under high low temperature, holding caducous problem.
Accompanying drawing explanation
Fig. 1 is the vertical view of the utility model pcb board fixture;
Fig. 2 is the cutaway view at the utility model pcb board fixture vertical view A-A place;
Fig. 3 is the upward view of the utility model pcb board fixture;
Fig. 4 is the partial view at the utility model pcb board fixture upward view I place.
In figure: 1. upper cover; 11. upper mounted plates; 2. base; 21. bottom plates; 22. arc clamping parts; 3. pcb board; 4. coil groups.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, be the vertical view of the utility model pcb board fixture, comprise base 2, pcb board 3 and coil groups 4.
If Fig. 2 is the cutaway view at the utility model pcb board fixture vertical view A-A place, comprise upper cover 1, upper mounted plate 11, base 2, bottom plate 21, pcb board 3;
Upper mounted plate 11 upper ends are fixedly connected with upper cover 1 inner bottom surface, and upper mounted plate 11 lower ends prop up pcb board 3 upper surfaces,
Bottom plate 21 lower ends are fixedly connected with base 2 bottom surfaces, and bottom plate 21 upper ends are set to L-type, block pcb board 3 lower surfaces and side.
Can obtain thus, upper mounted plate 11 and bottom plate 21 have limited the motion of pcb board 3 on Z direction and directions X.
If Fig. 3 is the upward view of the utility model pcb board fixture, comprise base 2, arc clamping part 22 and pcb board 3.
If Fig. 4 is the partial view at the utility model pcb board fixture upward view I place, comprise base 2, arc clamping part 22.Arc clamping part 22 is arranged on base 2 medial surfaces, and arc clamping part 22 blocks the side of pcb board 3, and the access section of the side of pcb board 3 is provided with the arc-shaped depression portion corresponding with described arc clamping part 22.
Thus, arc clamping part 22 has limited the motion in directions X and Y-direction.
To sum up, the Integrated using of upper mounted plate 11, bottom plate 21 and arc clamping part 22 has limited the motion of pcb board 3 in X, Y, Z direction, thereby has well fixed pcb board 3.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
