The utility model discloses novel structure adopts the copper wire winding to form the shielding layer, reduces the use of copper foil, and production process is simple, and low in production cost guarantees the shielding effect when practicing thrift manufacturing cost.

Description

High-speed cable

Technical Field

The utility model relates to a circuit construction technical field specifically is a high-speed cable.

Background

High-speed cable is common circuit equipment in life, all play key effect in fields such as power transmission, information transmission, general cable has single strand or stranded wire and insulating layer to constitute, power cable, control cable, compensation cable, shielded cable, high temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable etc. and high-speed cable then further promotes transmission rate on this basis, in order to guarantee that high-speed cable reduces the interference in carrying out the transmission process, generally be equipped with the shielding layer in high-speed cable.

The existing high-speed cable shielding layer is generally wrapped by aluminum foil or copper foil, the production process of similar metal foil is complex, and a good shielding effect can be achieved only by wrapping multiple layers, the production cost is high, if the aluminum foil is selected, the cost is saved on raw materials, but in the actual use process, the shielding effect of the aluminum foil is far inferior to that of the copper foil, and the product quality cannot be guaranteed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.

The utility model provides a high-speed cable, includes sinle silk 1 and wraps up inner insulating layer 4, outer insulating layer 3 of sinle silk 1 from interior to exterior in proper order, and the surface of inner insulating layer 4 closely twines has the copper foil wheat to draw and forms the inner shield layer, and the surface on inner shield layer closely twines has stranded copper wire to form the copper wire shielding layer, and outer insulating layer closely wraps up in the surface of copper wire shielding layer.

Furthermore, the material of the outer insulating layer is one of hot melt mylar or aluminum foil mylar.

Furthermore, the inner insulating layer is made of Teflon.

Furthermore, the wire core is made of copper, and the surface of the wire core is plated with silver.

Compared with the prior art, the utility model discloses the beneficial effect who gains does: the utility model discloses novel structure adopts the copper wire winding to form the shielding layer, reduces the use of copper foil, and production process is simple, and low in production cost guarantees the shielding effect when practicing thrift manufacturing cost.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.

Fig. 1 is a schematic structural diagram of the high-speed cable of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a high-speed cable includes a wire core 1, an inner insulating layer 4 and an outer insulating layer 3, the inner insulating layer 4 and the outer insulating layer 3 sequentially wrapping the wire core 1 from inside to outside, a copper foil mylar is tightly wound on the surface of the inner insulating layer 4 to form an inner shielding layer 2, a plurality of copper wires are tightly wound on the surface of the inner shielding layer 2 to form a copper wire shielding layer 5, and the outer insulating layer 3 is tightly wrapped on the surface of the copper wire shielding layer 5.

Further, the material of the outer insulating layer 3 is one of hot melt mylar or aluminum foil mylar.

Further, the inner insulating layer 4 is made of teflon.

Furthermore, the material of the wire core 1 is copper, and the surface of the wire core 1 is plated with silver.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
