Abstract
The utility model discloses a cable with a metal shielding layer, which comprises a sheath layer and at least two conducting wires of different colors comprising conductors and insulation layers outside the conductors. The conducting wires are packed in protection layer, and a metal shielding layer is arranged between the conducting wires and the sheath layer. Each conducting wire is marked with different figure and the metal shielding layer is made of tin plating metal wire. The utility model is characterized in that an electromagnetic circuit is formed inside the metal shielding layer due to the cable with the metal shielding layer when transferring current and signal, the outside electromagnetic wave interference to the electronic device and commercial installation can be prevented to improve the service performance.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of cable that has metal screen layer.
Background technology
At present, the cable that uses in the prior art, conductor outer wrapping one layer insulating is formed lead, wrap up one deck restrictive coating outward again by one or more lead, the cable of making thus is directly used in transmission of electricity or transmission signals, only has a transmitting effect, in the transmission of electricity process, the transmission of electric current can generate electromagnetic waves, and the external world exists a large amount of electromagnetic waves to produce the source, and the electromagnetic wave that is produced influences electronic equipment, industrial equipment easily, disturb the operate as normal of electronic equipment, industrial equipment, influence the performance of electronic equipment, industrial equipment.
The utility model content
The purpose of this utility model mainly is can't eliminate electromagnetic wave in the current delivery process according to common cable in the prior art, easily equipment is produced the shortcoming of disturbing, a kind of function of shielding that has is provided, reduces the cable that has metal screen layer that electromagnetic wave exerts an influence to equipment.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Have the cable of metal screen layer, comprise restrictive coating, lead, lead comprise that conductor and conductor are surrounded by insulating barrier outward, and lead is surrounded by restrictive coating outward, it is characterized in that, also have metal screen layer between described lead and the restrictive coating.
Preferably, described lead has more than two, and each root colour of insulated conductor is inequality.
Preferably, described lead is more than two, is marked with different digital on the every lead.
Preferably, described metal screen layer is a wire.
Preferably, described metal screen layer is the tin metal silk.
The cable that has metal screen layer in the utility model, in transmission current, signal, metal screen layer forms an electromagnetic circuit, can stop the external electromagnetic ripple to electronic equipment, and the interference of industrial equipment improves its serviceability.
Description of drawings
Fig. 1 is the utility model first embodiment sectional view;
Fig. 2 is the utility model second embodiment sectional view;
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is done a detailed description:
Referring to Fig. 1 and Fig. 2, lead 1 includes insulating barrier and conductor, and multiple conducting wires wraps in the restrictive coating 2, also has metal screen layer 3 between restrictive coating 2 and the lead 1, and metal screen layer 3 can be a wire, adopts zinc-plated form effect optimum.Lead 1 is two, and each root colour of insulated conductor has nothing in common with each other when above, perhaps with each root lead with figure notation to distinguish.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection range.
Claims (5)
1. the cable that has metal screen layer comprises restrictive coating, lead, and lead comprises that conductor and conductor are surrounded by insulating barrier outward, and lead is surrounded by restrictive coating outward, it is characterized in that, also has metal screen layer between described lead and the restrictive coating.
