CN203536004U - Signal line having metal wire braided sleeve - Google Patents

Abstract

The utility model provides a signal line having a metal wire braided sleeve. The signal line comprises conductors located in the innermost layer. Each of the conductors is externally wrapped with an insulator. The insulators are externally wrapped with the metal wire braided sleeve. The signal line provided by the utility model has a shielding function and is capable of effectively reducing the attenuation of signals. At the same time, the signal line can be used as a ground wire. The application amount of insulating materials is reduced, so that the cost is lowered.

Description

A kind of metal wire wired tube holding wire

Technical field

The utility model relates to electric wire and holding wire technical field, particularly a kind of metal wire wired tube holding wire.

Background technology

The holding wire that prior art provides, be electric wire to follow insulator be by extrusion modling, its shield effectiveness is bad, easily produces signal attenuation, and metal use amount is large, cost is high.

Utility model content

The utility model provides a kind of metal wire wired tube holding wire, and shield effectiveness is good, can use as ground wire again, and cost is low.

To achieve these goals, the utility model provides following technical scheme:

A metal wire wired tube holding wire, comprising: be positioned at the conductor of innermost layer, described conductor is surrounded by insulator outward, and described insulator is surrounded by metal wire wired tube outward.

Preferably, described conductor is three, and every described conductor is all surrounded by described insulator outward, and all described conductors and described insulator are all positioned at same metal wire wired tube,

Preferably, on the outer wall of described insulator, be provided with single note bar.

By implementing above technical scheme, there is following technique effect: the holding wire that the utility model provides, with function of shielding, can effectively reduce the decay of signal, can use as ground wire again, reduce the use amount of metallic conductor and insulating material simultaneously, cost-saving.

Accompanying drawing explanation

The structural representation of the holding wire that figure l provides for the utility model.

Embodiment

In order better to understand the technical solution of the utility model, below in conjunction with accompanying drawing, describe the embodiment that the utility model provides in detail.

The utility model embodiment provides a kind of metal wire wired tube holding wire, as shown in Figure 1, comprising: be positioned at the conductor 101 of innermost layer, the outer insulator 102 that is surrounded by of described conductor 101, the outer metal wire wired tube 103 that is surrounded by of described insulator 102.

In the above-described embodiments, more specifically, described conductor 101 is three, and every described conductor 101 is outer is all surrounded by described insulator 102, and all described conductor 10l and described insulators 102 are all positioned at same metal wire wired tube 103.

This holding wire, with function of shielding, can effectively reduce the decay of signal, can use as ground wire again simultaneously, reduces the use amount of metallic conductor, cost-saving.

In addition, in other embodiments, on the various embodiments described above basis, further, on the outer wall of described insulator 102, be provided with single note bar, to distinguish the different conductor in this sheath by this list note bar.

A kind of metal wire wired tube holding wire above the utility model embodiment being provided is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
