Abstract
The utility model provides a flexible cable shielding structure, comprising a gold finger, a flexible cable body, a grounding wire and a metal tape, and further comprising a metal foil which is attached together with the surface of the flexible cable body, wherein the grounding wire is reversely folded on the surface of the metal foil; the metal tape coats on the surface of the flexible cable body and covers on the metal foil so as to achieve contact and conduction. In the flexible cable shielding structure, one metal foil is added at the reversely-folded grounding wire of the flexible cable to form a whole conducting body with the grounding wire, the contact area between the grounding wire and the metal tape is increased, and the effects of improving the grounding resistance and keeping stable grounding resistance are achieved, so that the grounding resistance of the flexible cable is reduced, and the stability of a grounding function of a product is enhanced.
Description
Technical field
The utility model relates to the flexible flat cable field, relates in particular to a kind of flexible flat cable shielding construction.
Background technology
(Flexible Flat Cable is that assembly is used in a kind of signal transmission FFC) to flexible flat cable, itself has and can therefore be used in widely in many electronic products arbitrarily around advantages such as song, high signal transmission.This flexible flat cable is to use with the electric power connector collocation, so that signal is passed to the other end by an end, reaches the purpose that signal transmits.
Existing, as shown in Figure 1, 2, the ground wire of flexible flat cable and metal adhesive tape (as aluminium foil, Copper Foil, silver foil, conductive fabric etc.) are when interconnecting ground connection, it is ground wire reflexed with the FFC flexible flat cable, again the metal adhesive tape is attached to FFC flexible flat cable surface or coats the FFC flexible flat cable and the ground wire of covering reflexed, utilize the fixing ground wire of FFC flexible flat cable of conducting resinl on the metal adhesive tape, make ground wire and metal adhesive tape be interconnected to form path, reach the effect of shielding and ground connection.
But can bring following problem like this:
1, impedance ground is big, causes weak effect even inefficacy; Rely on metallic in the metal adhesive tape conducting resinl to reach the effect of ground connection with surperficial contact of ground wire of reflexed, be subjected to the width of ground wire of reflexed and the restriction of length, the contact area of metallic and ground wire is limited, can't guarantee the effect of ground connection.
2, poor stability, FFC flexible flat cable be subjected to the external force complications, deflect after, impedance ground changes greatly, causes the product function instability.
Summary of the invention
The purpose of this utility model is to provide a kind of flexible flat cable shielding construction.
The purpose of this utility model is achieved through the following technical solutions.
A kind of flexible flat cable shielding construction, comprise: golden finger, flexible flat cable body, ground wire and metal adhesive tape, also comprise the metal forming that fits together with the flexible flat cable body surface, described ground wire reflexed is on the surface of metal forming, described metal adhesive tape be coated on the flexible flat cable body surface and cover ground wire and metal forming on, to reach the contact conducting.
Preferably, described metal adhesive tape is aluminium foil, Copper Foil, silver foil or conductive fabric.
Preferably, described metal forming is aluminium foil, Copper Foil or silver foil.
The utility model embodiment compared with prior art, beneficial effect is: the utility model adds the integral body of a metal forming and a conducting of ground wire composition by the ground wire place at the flexible flat cable reflexed, increased the contact area of ground wire and metal adhesive tape, reached and improve impedance ground, the stable effect of maintenance impedance ground.Thereby reduce the flexible flat cable impedance ground, strengthen the stability of product grounding function.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Fig. 3,4,1 is the flexible flat cable body among the figure, and 2 is the flexible flat cable golden finger, and 3 is the flexible flat cable ground wire, and 4 is the metal adhesive tape, and 5 is metal forming;
Metal forming 5 is fitted with the surface of flexible flat cable 1;
Ground wire 3 reflexeds are the surperficial of metal forming 5 and make the two mutual conduction;
The metal adhesive tape 4 that bonding is used is coated on the surface of FFC flexible flat cable body 1 and covers ground wire 3 and metal forming 5; The interior conducting particles of metal adhesive tape 4 incidental conducting resinls is contacted with ground wire 3 and metal forming 5 and conducting, reach the effect of shielding and ground connection from face.
Metal adhesive tape 4 can be aluminium foil, Copper Foil, silver foil, conductive fabric etc.
Metal forming 5 can be aluminium foil, Copper Foil, silver foil etc.
The utility model has increased the contact area of ground wire and metal adhesive tape by the integral body that the ground wire place at the flexible flat cable reflexed adds a metal forming and a conducting of ground wire composition, reaches to improve impedance ground, the stable effect of maintenance impedance ground.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
