Description

Mobile installation communication cable

Technical field

Communication cable is the utility model is related to, more particularly to a kind of mobile installation communication cable.

Background technology

At present, many communication cables both increase shielded layer outside each pair line, are adopted to reduce interfering with each other between line pair The mode taken is generally aluminum foil shielded, winding shielding or braid shielded.But when communication cable actual use needs often movement When, due between each part inside electric wire can phase mutual friction, the abrasion between each pair shielded layer can be caused, with making With the extension in cycle, after shielded layer breakage, density meeting rapid decrease, until shielding failure.To avoid the mobile order wire installed Friction in movement between inner shield, the mode that can generally take increases by one layer of inner sheath outside inner shield are made to play protection With.Another scheme is wrapped one layer of twining package tape outside internal shield.

It but can need certain to avoid the friction between shielded layer, inner sheath although increasing the scheme of inner sheath Thickness (generally at least needs the thickness of 0.4mm, too thin to process), this can increase electric wire inner structure size, cause electricity Line overall dimensions increase, and are unfavorable for installing.At the same time also increase material cost, electric wire processing cost and it is supporting installation part into This.Although the scheme of another twining package tape does not influence material cost and wire size, parcel is more open, curved During easily fold it is damaged, macrocyclic protecting effect is very poor.

The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the utility model, and It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form Technology.

Utility model content

The purpose of this utility model is to provide the mobile installation communication cable of one kind, the size of the twisted core in inside is small, subtracts Light line will not wrinkle phase mutual friction because of wire bend.

To achieve the above object, the utility model provides a kind of mobile installation communication cable, including some groups of cored wires, often There is internal shield outside group cored wire, the gap between every group of cored wire is equipped with filled layer, and some groups of cored wires are wrapped with outer layer, every group The internal shield of cored wire is wrapped with the drawing of hot melt wheat.

Preferably, hot melt wheat is pulled through heating and wraps and be attached to internal shield outer surface.

Preferably, hot melt wheat, which is drawn, drags bag outside the internal shield of every group of cored wire.

Preferably, outer layer includes nonwoven layer, organization level and oversheath from the inside to the outside.

Preferably, internal shield is single side aluminium foil.

Compared with prior art, the utility model has the advantages that：By to every group of cored wire inside cable Outside internal shield by the way of hot melt wheat is drawn, since hot melt wheat draws outer layer unusual light, avoid shielded layer from being rubbed, extend Service life, also functions to and plays the role of protecting internal shield, and thickness only 0.03mm or so, and hardly increase is internal twists The size of cored wire is closed, reduces material cost and wire size.

Brief description of the drawings

Embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain and from the limitation of embodiment.

Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members Part or other parts.

As shown in Fig. 2, according to the mobile installation communication cable of one kind of the utility model embodiment, including some groups Cored wire 1, has internal shield 2 outside every group of cored wire 1, and the gap between every group of cored wire 1 is equipped with filled layer 4, some groups of 1 outsourcings of cored wire Outer layer is wrapped with, the internal shield 2 of every group of cored wire 1 is wrapped with hot melt wheat and draws 3.

In such scheme, drawn by increasing hot melt wheat to the outer layer of every group of cored wire inside cable, play screen in protection The effect of layer, while thickness only 0.03mm or so are covered, hardly increases the size of internal stranded core, reduces material cost And wire size.Wheat is heated at the same time and draws outer layer unusual light, is played and is mitigated each line to phase mutual friction, extends service life. This programme substitutes the mode (referring to Fig. 1) of existing inner sheath 31, can significantly reduce the outside diameter of cable.

As a kind of preferred embodiment, hot melt wheat draws 3 to drag bag outside the internal shield 2 of every group of cored wire 1, using dragging bag Processing method, is greatly improved production efficiency.

As a kind of preferred embodiment, hot melt wheat draws 3 to be attached to 2 outer surface of internal shield by heating to wrap.This programme In, hot melt wheat draws 3 in processing, after heater, can shrink, and bag that thus can be tightly is attached on internal shield 2, It will not wrinkle because of wire bend.

As a kind of preferred embodiment, outer layer includes nonwoven layer 5, organization level 6 and oversheath 7 from the inside to the outside.

As a kind of preferred embodiment, internal shield 2 is single side aluminium foil.

To sum up, the mobile installation communication cable of the present embodiment, by the internal shield to every group of cored wire inside cable outside By the way of hot melt wheat is drawn, since hot melt wheat draws outer layer unusual light, avoid shielded layer from being rubbed, extend service life, Also function to and play the role of protecting internal shield, and thickness only 0.03mm or so, hardly increase internal stranded core Size, reduces material cost and wire size.

The description of the foregoing specific exemplary embodiment to the utility model be in order to illustrate and illustration purpose.These Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explain the certain principles of the utility model And its practical application, so that those skilled in the art can realize and utilize a variety of examples of the utility model Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shape Formula is limited.
