The utility model has the functions of shielding the interference signal and protecting edges of the printed circuit board and the advantages of simple structure, good interference signal shielding effect and long service life of the printed circuit board.
Description
Technical field
The utility model belongs to a kind of printed circuit board (PCB) that can shield interference signal.
Background technology
Printed circuit board (PCB) is widely used in the various electronic equipments, as computer, television set, telephone set, mobile phone and various control equipment instruments etc.Printed circuit board (PCB) is setting element hole and fixing hole and be connected the printed circuit lines of various component holes on plate body usually, during use, corresponding various electronic components are inserted solid welding in the component hole of printed circuit board (PCB), form corresponding control circuit, again the fixing hole of use in printed circuit board on it fixed with corresponding casing for electric appliances, formed various electronic equipments.Some electronic equipment service condition is abominable, as the printed circuit that uses in mobile phone or the automobile, often use under vibrations, high temperature or mal-conditions such as high pressure, humidity, the printed circuit board (PCB) periphery that uses insulating material to make very easily damages, ftractures, and causes the damage of printed circuit in it.On the other hand, the printed circuit on the printed circuit board (PCB) in use also is subjected to the interference in non-self various signal of telecommunication or telecommunications magnetic field easily, influences the normal use of electronic equipment.
Summary of the invention
The purpose of this utility model is a kind of printed circuit board (PCB) that can shield interference signal of design, and the effect that can shield interference signal and protection printed circuit board (PCB) edges of boards is arranged, have simple in structure, the advantage of the good and printed circuit board (PCB) long service life of shielding interference signal.For this reason, the utility model mainly is made up of plate body and component hole, and at the side of plate body, or the periphery of plate body, or the side of plate body and periphery are provided with the metal level that fuses with plate body that can shield interference signal.Described metal level is the side with plate body, or the periphery of plate body, or the conductive metal thin plate that is bonded into one of the side of plate body and periphery.Described metal level is the electrotinning layer.Described metal level is a copper electroplating layer.Described metal level is an electroplating aluminum coating.Said structure has reached the purpose of this utility model.
The utility model has the effect that can shield interference signal and protection printed circuit board (PCB) edges of boards, have simple in structure, the advantage of the good and printed circuit board (PCB) long service life of shielding interference signal.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a side structure schematic diagram of the present utility model.
Specific embodiments
As depicted in figs. 1 and 2, a kind of printed circuit board (PCB) that can shield interference signal mainly is made up of plate body 1 and component hole 2.At the side of plate body, or the periphery of plate body, or the side of plate body and periphery are provided with the metal level 4 that fuses with plate body that can shield interference signal.Also be provided with fixing hole 3 on the plate body, be used for printed circuit board (PCB) is fixed with corresponding casing for electric appliances.
Described metal level is the side with plate body, or the periphery of plate body, or the conductive metal thin plate that is bonded into one of the side of plate body and periphery.The side of conductive metal thin plate and plate body is bonded into one, and can effectively protect printed circuit board (PCB) normally to use under mal-condition, can effectively shield interference signal again, makes the normal use of electronic equipment.Conductive metal thin plate also can be bonded into one with the periphery of plate body.Or also can be bonded into one with the side and the periphery of plate body.The thickness of conductive metal thin plate is 0.01～0.1mm.
Described metal level is the electrotinning layer.Described metal level is a copper electroplating layer.Described metal level is an electroplating aluminum coating.Metal level also can be other electrodeposition of metals.
In a word, the utility model has the effect that can shield interfering signal and protection printed circuit board (PCB) edges of boards, have simple in structure, the advantage of the good and printed circuit board (PCB) long service life of shielding interfering signal.
