Background technology
Development gradually along with electronic technology, the complexity of wiring board is also increasing gradually, the quantity of integrated chip is also in continuous increase on wiring board, this just causes the line between the chip complicated, the summation length of line increases, the heat that chip produces also can increase, and for guaranteeing the long-time operate as normal of chip, need in time distribute the heat of generation.
Wiring board outside being directly exposed to sometimes, can improve radiating effect like this when installing and using, but the wiring board exposure has also brought some hidden danger.Dust is accumulated on the wiring board easily, cause on the wiring board to be short-circuited between the pin of chip, and after the wiring board exposure, chip pin is collided by foreign object easily, causes pin loosening, may produce the signal transmission thus and interrupt.
Patent Office of the People's Republic of China has announced a CN2468723Y document on January 2nd, 2002; name is called mini-printer wiring board protective cover; this protective cover forms three side sealing and closes by two side, roof; have one can expose the slotted hole of flat cable line cap and the hole that can expose the power line port at the rear portion of protective cover, the projection of installation and positioning convex are arranged on the sidewall of protective cover.But this protective cover is a kind of structure of similar housing, and the parts of protection also have various data wires except wiring board, and the space of causing protective cover to form is bigger, and data wire is not separated mutually with wiring board.
Summary of the invention
The utility model has solved in the prior art wiring board and has been in exposed state and accumulates the defective that dust causes the short circuit of circuit board and chip pin easily; provide a kind of wiring board cover sheet that wiring board is covered and prevent that dust from falling on the wiring board, solve the pin problem of short-circuit.
The utility model has also solved in the prior art wiring board and has been exposed to the outer pin that makes and is caused the loosening defective of pin by collision easily, and a kind of wiring board cover sheet is provided, and wiring board is covered prevent that pin from being collided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of wiring board cover sheet; comprise cover plate main body; it is plane that cover plate main body is; the surface attachment that it is characterized in that cover plate main body has one deck insulated liner; cover plate main body is provided with a plurality of wiring board fixing holes; the both sides of cover plate main body are provided with the cover plate holddown groove of opening, and the side of cover plate is provided with the L-shaped grab perpendicular with cover plate main body.Cover plate main body is that plane and wiring board are more approaching, the insulated liner on surface can play insulating effect, thereby prevent the influence of static to wiring board, can prevent that also static is delivered to the casing outside by the wiring board cover plate, the position of wiring board fixing hole and quantity are according to the concrete shape set of wiring board, the wiring board fixing hole is according to floor plan, thereby support and fixing circuit board, when the wiring board size is big, the quantity of wiring board fixing hole increases, by screw-driving wiring board is fixed, and made wiring board cover plate and wiring board develop, prevent that the wiring board size from may produce the problem of distortion more greatly; The cover plate holddown groove is used for fixing with machine frame, and the cover plate holddown groove is the opening shape, can conveniently connect in conjunction with the grab of L type, grab is aimed at link slot corresponding on the machine frame, and push away forward, the cover plate holddown groove just can snap onto the connection hole of machine frame, directly be screwed, use more convenient.
As preferably, totally 2 of cover plate holddown grooves are in the end position and the outstanding cover plate main body side of cover plate main body both sides, and the cover plate holddown groove takes the shape of the letter U.Have only cover plate holddown groove raised side, so also have only these two positions and machine frame overlapping, prevent that cover plate main body and machine frame from interfering, the cover plate holddown groove takes the shape of the letter U, and the bayonet socket of U-shaped conveniently snaps onto the connection hole of machine frame outwardly.
As preferably, the cross section of the cover plate holddown groove of U-shaped is Z-shaped, and Z-shaped difference in height is the thickness of cover plate main body.The cross section is Z-shaped, makes the end of cover plate holddown groove form bending, and when cover plate main body was connected with machine frame, the difference in height of bending made that just in time the surface of cover plate main body is mutually concordant with the edge of the corresponding connecting portion of machine frame.
As preferably, the wiring board fixing hole comprises two of being in side and three of mediating, and each wiring board fixing hole is convex.The wiring board fixing hole of projection can separate PCB surface and cover plate main body surface, thereby prevents to damage pin.
As preferably, be attached with the insulation spacer that the PET material is made on the wiring board fixing hole, the shape of the shape of this insulation spacer and wiring board fixing hole matches.
As preferably, the downside of cover plate main body is provided with connecting groove, and the side opposed side edges two ends with the connecting groove place on the cover plate main body are provided with described wiring board holddown groove.
As preferably, be provided with flange around the cover plate main body, the wrap direction of flange is identical with the wrap direction of grab, and the height of flange equates with the height of wiring board fixing hole.Flange can be strengthened the intensity of cover plate main body, also shallow scrimp can be set on the cover plate main body surface simultaneously, to improve intensity.
The beneficial effects of the utility model are: insulated liner can make the wiring board cover plate form an insulating element, the static sound equipment just can not caused to wiring board in the fixing back of wiring board cover plate and wiring board, grab combined circuit board holddown groove is fixed with casing after making things convenient for wiring board cover plate connection line plate.
