Description
Technical field
The utility model is related to a kind of flexible PCB more particularly to a kind of ground connection flexible PCBs.
Background technology
Flexible PCB is that have height reliability as one kind made of base material using polyimides or polyester film, excellent
Flexible printed circuit, abbreviation FPC.Since it has the characteristics that Distribution density is high, light-weight, thickness is thin, in hyundai electronics
It is used widely in production, is applied especially to small device.But small device is since component distance is near, can generate compared with
Big electromagnetic interference, in this regard, often using ground connection flexible PCB in current practical application（It is grounded FPC）Anti- electromagnetism is improved to do
Immunity energy.
Existing ground connection FPC is one piece of grounding plate of stickup on FPC, and connector of the cooperation with ground terminal makes
With after FPC is inserted into connector, the metallic plate on FPC can be in direct contact with connector ground terminal, can significantly improve it
Electromagnetism interference performance, but this kind ground connection FPC can but bring other problems.
As shown in Figure 1 and Figure 2, since grounding plate 3 is pasted onto on flexible circuit 1, metallic plate has certain high
Degree, when FPC to be inserted into the connector 4 with ground terminal 5, grounding plate 3 inevitably scratches ground terminal 5,
And then it leads to the problem of 5 surface metal plating layer of ground terminal and comes off.The gold being detached from due to grounding plate 3 scratches ground terminal 5
Belonging to coating will enter with then insert action inside connector 4, if the coat of metal being detached from falls into two in connector 4
Between golden finger, it will lead to short circuit；Between two golden fingers are fallen, the gold that is present in inside connector 4
Belong to the problems such as clast may also lead to signal interference, scratch 2 grade of golden finger.
Utility model content
The utility model aim is to provide a kind of ground connection flexible PCB, it is intended to which solving ground connection flexible circuit at present can scrape
The problem of hindering ground terminal, ground terminal surface metal plating layer caused to come off.
A kind of ground connection flexible PCB described in the utility model, the flexible circuit including golden finger and connection golden finger,
The flex circuit surface of golden finger rear end is pasted with grounding plate, and grounding plate is located proximate to golden finger and is pasted onto and gold
The flex circuit surface of finger metal covering homonymy, the grounding plate are provided with and grounded metal at golden finger direction
The reinforcement dam of plate connection, reinforcement dam thickness is identical with grounded metal plate thickness, is made of flexible insulating material.
A kind of ground connection flexible PCB described in the utility model sets reinforcement dam in grounding plate close to golden finger,
When FPC is inserted into connector, reinforcement dam is first connect with ground terminal, since reinforcement dam is made of flexible insulating material,
Hardness opposing metallic is smaller will not to scratch ground terminal, and because reinforcement dam thickness is identical with grounded metal plate thickness, be inserted into
Reinforcement dam is first inserted into connector during FPC, and ground terminal is made to push suitable distance, the grounding plate subsequently entered
Nature and ground terminal contact, grounding plate can not possibly scratch ground terminal, and also there is no ground terminal surface metal plating layers
The problem of coming off.This kind is grounded flexible PCB, increases reinforcement dam on the basis of existing ground connection flexible PCB, passes through benefit
Strong dam solves the problems, such as that grounding plate scratches ground terminal, and solving existing ground connection flexible PCB with extremely low cost deposits
A huge problem.

Fig. 2 is the schematic diagram that existing ground connection flexible circuit is inserted into connector；
Fig. 3 is a kind of cross-sectional view for being grounded flexible circuit described in the utility model；
Fig. 4 is a kind of schematic diagram for being grounded flexible circuit and being inserted into connector described in the utility model
Fig. 5 is the cross-sectional view of another ground connection flexible circuit described in the utility model.
Specific embodiment
As shown in figure 3, a kind of ground connection flexible PCB, the flexible circuit 1 including golden finger 2 and connection golden finger, golden hand
The flex circuit surface for referring to 2 rear ends is pasted with grounding plate 3, and grounding plate 3 is located proximate to golden finger 2, is pasted onto and gold
1 surface of flexible circuit of 2 metal covering homonymy of finger, the grounding plate 3 are provided with and are grounded at 2 direction of golden finger
The reinforcement dam 6 that metallic plate 3 connects, reinforcement dam thickness 6 is identical with 3 thickness of grounding plate, using flexible insulating material system
Into.As shown in figure 4, when FPC is inserted into connector 4, reinforcement dam 6 is first connect with ground terminal 5, since reinforcement dam 6 is using soft
Property insulating materials be made, hardness opposing metallic is smaller will not to scratch ground terminal 5, and because 6 thickness of reinforcement dam and ground connection gold
Belong to plate thickness 3 it is identical, reinforcement dam 6 is first inserted into connector 4 during FPC is inserted into, make ground terminal 5 push suitably away from
From, 3 nature of grounding plate subsequently entered is contacted with ground terminal 5, and grounding plate 3 can not possibly scratch ground terminal 5,
The problem of coming off there is no 5 surface metal plating layer of ground terminal.
As shown in figure 5, the reinforcement dam 6 is trapezoidal, reinforcement dam 6 is small close to 2 one end thickness of golden finger, and reinforcement dam 6 is close
The thickness of one end of grounding plate 3 is identical with 3 thickness of grounding plate.Reinforcement dam 6 is set as trapezoidal, with the insertion of FPC,
The thickness on reinforcement dam 6 gradually increases, can also better protective grounding terminal convenient for the insertion of FPC.
The reinforcement dam is adopted made of plastic, and the reinforcement dam is made of polyimide.
For those skilled in the art, technical solution that can be as described above and design are made other each
Kind is corresponding to be changed and deforms, and all these change and deform the guarantor that should all belong to the utility model claims
Within the scope of shield.
