Abstract

The invention provides a cable. The cable comprises at least one ground wire and a conductive body, wherein the conductive body has an outer layer with better conductivity and an inner layer, wherein the conductivity of the inner layer is weaker than that of the outer layer; and the ground wire is positioned between the outer layer and the inner layer, and is in contact with the inner layer and the outer layer. Compared with the prior art, the cable provided by the invention has the advantages of anti-electromagnetic interference function, simple process and convenience for making.

Description

Cable

[technical field]

The present invention relates to a kind of cable, particularly relate to a kind of cable with anti-electromagnetic interference function.

[background technology]

At present, in electronic equipment use procedure, more or less there will be electromagnetic interference, how improving anti-electromagnetic interference capability is the problem that electron trade must solve.Increasing except the function of electromagnetism interference parts except proposing electronic building brick itself, also requiring that the cable to electronic building brick increases the function of electromagnetism interference.

In August 11 calendar year 2001 Chinese Taiwan Patent announce No. 450408 and disclose a kind of cable structure, this cable forms by some thin cable institute is coated, it is included in innermost layer and has several thin cable, one first separator is coated with in these thin cable, this first separator is an aluminium foil material, one second separator is coated with outward again in the first separator, second separator is conductive plastics material, separately there is an earth connection between the first separator and the second separator, be finally coated with an insulating barrier again in this second separator outer rim.This cable reduces electromagnetic interference really to a great extent, but this cable is the ability increasing electromagnetism interference, and use multiple separator, and production technology is more complicated, processing cost is higher.

Therefore, be necessary to provide a kind of cable to overcome the problems referred to above.

[summary of the invention]

Main purpose of the present invention is to provide a kind of technique simple and the cable with anti-electromagnetic interference function.

For achieving the above object, the present invention can adopt following technical scheme: a kind of cable, comprise at least one earth connection and electric conductor, electric conductor has conductivity preferably outer and internal layer that conductivity is more weak relative to described skin, described earth connection between described skin with described internal layer and, internal layer outer with described contact.

For achieving the above object, the present invention also can adopt following technical scheme: a kind of cable, comprise at least one exposed metallic conductor and electric conductor, electric conductor has conductivity preferably outer and internal layer that conductivity is more weak relative to described skin, described metallic conductor between described skin with described internal layer and, internal layer outer with described contact.

Compared with prior art, the beneficial effect of cable of the present invention is: the function with electromagnetism interference, and technique is simple, easy to make.

[accompanying drawing explanation]

Fig. 1 is the three-dimensional assembly diagram of cable of the present invention.

Fig. 2 is the front view of cable shown in Fig. 1.

[embodiment]

Please refer to shown in Fig. 1 to Fig. 2, cable 1 of the present invention comprises earth connection 2, holding wire 3, the insulated hull 4 of coated holding wire 3 and the electric conductor 5 of coated earth connection 2 and insulated hull 4.

Earth connection 2, holding wire 3 are for having the metal wire of conduction function, and its material is the existing metal wire such as copper, aluminium.

Electric conductor 5 has two-layer, comprises the conductivity internal layer 52 that skin 51 is more weak with the conductivity of opposed outer layer 51 preferably.Electric conductor 5 is through being bent to form three-decker, comprise ground floor 501, the second layer 502 and third layer 503, above-mentioned three layers are arranged above and below successively, and ground floor 501 is connected with third layer 503, the second layer 502 is connected with third layer 503, and the second layer 502 is between ground floor 501 and third layer 503.Skin 51 is positioned at the periphery of whole piece cable 1, and in ground floor 501, outer 51 are positioned at above internal layer 52, and in the second layer 502, outer 51 are positioned at above internal layer 52, and in third layer 503, outer 51 are positioned at below internal layer 52.

Earth connection 2 is exposed metallic conductor, between ground floor 501 and the second layer 502, its earth connection 2 is in contact with the skin 51 of electric conductor 5 and the internal layer 52 of electric conductor 5, between the internal layer 52 of earth connection 2 in ground floor 501 and the skin 51 of the second layer 502.

Insulated hull 4 is between the second layer 502 and third layer 503, and its insulated hull 4 contacts with the internal layer 52 of electric conductor 5, between the internal layer 52 of earth connection 2 in ground floor 501 and the internal layer 52 of the second layer 502.Some holding wires 3 with insulated hull 4 form a line, and certainly, in other embodiments, some holding wires 3 also can be stacked.

Outer 51 materials are metal forming, also can for having the scrim of the coat of metal, and internal layer 52 has the conducting resinl (not shown) of stickiness.Internal layer 52 is as sticking together fixing use time coated, conducting resinl is scattered with the conductor powder (not shown) of conduction, and conductor powder is not for connecting conducting path, its conducting resistance is higher, its conduction pattern is called vertical conducting in engineering, and relative material is that the resistance of the skin 51 (horizontal conducting) of metal forming can be higher.Because the height of resistance and the ability of electromagnetism interference are inverse ratio, so, reduce resistance and can improve anti-electromagnetic interference capability.The present invention is contacted with earth connection 2 by the skin 51 that resistance is less, can reduce the resistance of whole piece cable 1, thus, improve anti-electromagnetic interference capability.

The present invention, by means of only an electric conductor 5, can make the coated earth connection 2 of internal layer 52, and outer 51 can be made again to contact to improve better conduction with earth connection 2.Production technology is simple, easy to make.
