Abstract
The utility model relates to the technical field of a circuit board, in particular to a shielding cavity for a printed circuit board (PCB), which comprises a shielding cavity main body. The main body forms a fence shape, and the edge forms a wall shape. The vertical height of the main body is 1.5 mm-2 mm. The fence of the edge of PCB is provided with a notch. The method reduces the welder amount for the fence welded on the PCB, provides gap for the moving line to penetrate through the fence, and has no need of adopting any particular moving line gap through hole or multiple PCBs. The utility model has the advantages of reasonable design, skillful concept, simple process and high production efficiency, and has popularization value.
Description
Technical field
The utility model relates to the circuit board technology field, especially a kind of use in printed circuit board shielding cavity.
Background technology
At present, at printed circuit board industry, shielding cavity is the four sides cavity, and common four sides cavity often adopts the seam weldering that it is welded on the pcb board along one section continuous cabling.When judging the fence height, the designer needs fence bottom scolding tin fillet thickness is taken into account.Fence the edge all be welded on the pcb board, influenced the cabling that passes the fence border, and the amount of solder that fence is welded on the pcb board increases, not only inconvenient operation, and operability is not strong.Certainly will increase hand labor power like this, operating efficiency is not high, has prolonged the Production Time of plank, thereby causes cost to rise.
The utility model content
In order to overcome the deficiency that existing shielding cavity operating efficiency is not high, cost is high, the utility model provides a kind of use in printed circuit board shielding cavity.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of use in printed circuit board shielding cavity, comprise the shielding cavity body, and body becomes the fence shape, and the edge of body is the city wall shape.
According to another embodiment of the present utility model, the vertical height that further comprises body is 1.5mm-2mm.
The beneficial effects of the utility model are, make the fence at PCB edge jagged, this method has reduced fence has been welded in amount of solder on the pcb board, also provides the gap for cabling passes the fence border, and need not adopt specific track gap via hole or multi-layer PCB board.This shielding cavity is rational in infrastructure, be skillfully constructed, and technology is simple, and the production efficiency height has promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
1. bodies, 2. edge among the figure.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is structural representation of the present utility model, and a kind of use in printed circuit board shielding cavity comprises shielding cavity body 1,1 one-tenth fence shape of body, and the edge 2 of body 1 is the city wall shape.The vertical height of body 1 is 1.5mm-2mm.Being combined together of this shielding cavity and PCB compactness, saved the space, the fence at PCB edge 2 is made the city wall shape, this method has reduced fence has been welded in amount of solder on the pcb board, also provide the gap, and need not adopt specific track gap via hole or multi-layer PCB board for cabling passes the fence border.This shielding cavity is rational in infrastructure, be skillfully constructed, and technology is simple, and the production efficiency height has promotional value.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (2)
1. a use in printed circuit board shielding cavity comprises shielding cavity body (1), it is characterized in that, body (1) becomes the fence shape, and the edge (2) of body (1) is the city wall shape.
