Abstract
The utility model provides a shield for a printed circuit board, which is a shield mounted at the bottom of a general printed circuit board and can cover the pins of constituent units at the bottom of the printed circuit board; in addition to eye-pleasing and dust-proof effects and the like, the shield can even prevent the pointed pins from scraping hands of operating staff or operating table surface and can protect the layout of circuit to avoid the occurrence of short circuit.
Description
Technical field
The utility model relates to a kind of protective cover of printed circuit board (PCB), refers to a kind of the linking in printed circuit board (PCB) bottom especially, scrapes hand and scrapes the operation table top and can protect printed circuit board (PCB) preventing, avoids causing the protective cover of the printed circuit board (PCB) of short circuit phenomenon.
Background technology
Press, the printed circuit board (PCB) (Printed Circuit Board is called for short PCB) of general computer-internal, as shown in Figure 1, the formation of these printed circuit board (PCB) 100 circuit, be to make transistor, resistor, the capacitor of finishing earlier ... wait each component unit 101 to be welded on the printed circuit board (PCB) 100, use welding compound (Solder) to weld each component unit 101 again and form a circuit; In addition, be respectively equipped with perforation 103 on printed circuit board (PCB) 100 surroundings, so that place screw locking printed circuit board (PCB) 100.Consult shown in Figure 2, the bottom of printed circuit board (PCB) 100, the pin 102 and the welding compound of each component unit 101 forms the prominent structure of some points, and in the operation personnel were taking assembling process, the structure that this point is dashed forward is scratch operating personnel's hand or scratch operation table top very easily; Moreover some dusts can be infected with in printed circuit board (PCB) 100 bottoms, and long-term accumulated is got off and can be caused short circuit, and printed circuit board (PCB) 100 therefore commonly used is not except more attractive in appearance, and the circuit layout of its bottom is not protected again, and haves much room for improvement.
The utility model designer in view of this, the industry experience for many years is engaged in accumulation, is study intensively and test improvement repeatedly, nowadays designs a kind of protective cover of novel printed circuit board (PCB) finally, the product shortcoming commonly used of can forgoing is to promote effect.
The utility model content
Thus; main purpose of the present utility model is to provide a kind of protective cover of printed circuit board (PCB); mainly be in general printed circuit board (PCB) bottom clamping one protective cover; this protective cover is except the pin scratch staff that can prevent component unit or scratch the operation table top, having more dustproof and protective circuit layout and effect attractive in appearance.
Understand in order to allow your auditor that the utility model is had further, Zi Zuo is described in detail as follows the utility model with accompanying drawing:

Embodiment
See also shown in Figure 3, protective cover 10 of the present utility model is established for the size that cooperates general printed circuit board (PCB) 100, be respectively equipped with edge 11 on its surrounding, cooperate Fig. 4 and shown in Figure 5, protective cover 10 can fix in printed circuit board (PCB) 100 bottoms, is respectively equipped with projection 12 on these protective cover 10 surroundings, and projection 12 is provided with perforation 13, this perforation 13 is the perforation 103 of fit printed circuit board 100, so that screw runs through and printed circuit board (PCB) 100 and protective cover 10 are locked on computers simultaneously.
Above-mentioned protective cover 10 is connected has some advantages on printed circuit board (PCB) 100, is listed below one by one now:
Can prevent the scratch hand when 1, operating personnel's carrying, assembling.
Can prevent to scratch the operation table top when 2, operating personnel's carrying, assembling.
3, the dustproof effect of tool can be avoided circuit to be blocked by dust and cause short circuit phenomenon.
4, can protect the circuit layout of printed circuit board (PCB), damage to avoid the improper collision of printed circuit board (PCB).
5, has aesthetic.
In sum, the protective cover of the utility model printed circuit board (PCB) is installed in general printing for a kind of The protective cover of circuit board bottom except preventing scraping hand, scraping the operation table top, more can prevent dust to protect Circuit layout forms short circuit phenomenon to avoid circuit, and the tool aesthetic; Its practical effect when need not Doubt, and the utility model is never made the city know or seen other publication the real Patent Law that met Regulation, so propose patent application in accordance with the law.
Claims (2)
1, a kind of protective cover of printed circuit board (PCB) is characterized in that, is the protective cover that a kind of fit printed circuit board size is established, and is installed in the printed circuit board (PCB) bottom, and the perforation of the perforation fit printed circuit board of its surrounding runs through locking for screw.
2, the protective cover of printed circuit board (PCB) as claimed in claim 1 is characterized in that, the perforation on the protective cover surrounding is positioned on the projection.
