Abstract
The utility model discloses a novel steel wire indoor telephone line, which comprises four core wires and sheaths and further comprises a steel wire, wherein the four core wires and the steel wire are all wrapped inside the first sheath. More concretely, the four core wires are divided into two pairs, the second sheath is wrapped outside each pair of core wires, and then the first sheath is wrapped by two pairs of core wires wrapped with the second sheath together with the steel wire. A PE (Polyethylene) sheath is arranged outside the steel wire. The novel steel wire indoor telephone line has the advantages that the novel self-supporting indoor telephone line has the characteristics of being high in strength and convenient for aerial installation since a steel wire strengthening core structure is added in the sheath; and the novel steel wire indoor telephone line is very suitable for being paved in some areas with poor communication such as mountain area, and is economic and practical. Moreover, the PE sheath is coated on the surface of a steel wire strengthening core, which can reach the effect of insulation, prevents signal interference to a conductor for communication and also can prevent rusting.
Description
Technical field
The utility model relates to a kind of telephone wire, specifically a kind of self-bearing type telephone wire.
Background technology
Telephone wire is exactly the house lead in of phone, is connected on the telephone set.Traditional telephone wire has two cores and four-core, core line diameter has respectively 0.4 and 0.5, the certain areas has 0.8 and 1.0, its structure generally is two or four heart yearn outer wrapping polyethylene, common heart yearn material has copper covered steel, copper cover aluminum, full copper, heart yearn can be that twisted-pair feeder also can be parallel lines, the cored parallel telephone wires that the twisted pair telephone line contrast is common, and Main Function is the lower loss of raising and power aspect of transmission speed.
Existing its hot strength of telephone wire structures shape is limited, when the long distance of needs is installed, need to wirerope be set specially strengthens, otherwise break easily, particularly in some ungetable areas such as mountain area when installing, wirerope is set has specially increased the difficulty of construction greatly, and damages easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of novel steel wire indoor telephone line that has the intensity height, is convenient to built on stilts characteristics of installing.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of novel steel wire indoor telephone line, comprise four heart yearns, sheath, and also comprise a steel wire, described four heart yearns and a steel wire all are wrapped in the first sheath.
More specifically, described four heart yearns are divided into two pairs, and every pair of heart yearn is wrapped with the second sheath, and two pairs of heart yearns that are enclosed with the second sheath wrap up the first sheath together outside with steel wire again.
More specifically, described steel wire comprises one deck PE sheath outward.
The utility model has the advantage of: this kind Novel self-supporting phone service wire is owing to increased steel wire strengthening core structure in sheath, have the intensity height, be convenient to built on stilts characteristics of installing, be highly suitable for the built on stilts telephone wire of laying in the constant area of some traffic such as mountain area and register one's residence, economical and practical.And steel wire strengthening core surface-coated has the PE cover to mould layer, both can play insulating effect, avoids the signal of communication with conductor disturbed, and can prevent from again getting rusty.
Description of drawings
Fig. 1 is the structure chart of a kind of novel steel wire indoor telephone line of the utility model.
Embodiment
See also shown in Figure 1ly, a kind of novel steel wire indoor telephone line of the utility model comprises four heart yearns 1, a steel wire 2, sheath 3.
Described four heart yearns 1 and a steel wire 2 all are wrapped in the sheath 3, because increased steel wire 2 in sheath 3, have therefore increased the intensity of indoor telephone line, make it have the intensity height, be convenient to built on stilts characteristics of installing.
As the scheme of more optimizing, described four heart yearns 1 are divided into two pairs, the every pair of heart yearn 1 be wrapped with heart yearn 1 that 12, two pairs of sheaths are enclosed with sheath 12 again with steel wire 2 together wrap jacket 3 outside.
On the basis of above-mentioned two embodiments, also comprise one deck PE sheath 22 outside the described steel wire 2, both can play insulating effect, avoid the signal of communication with conductor disturbed, can prevent from again getting rusty.
Because the intensity of steel is larger, therefore can use thinner steel wire 2 to strengthen, the external diameter of the PE sheath 22 of parcel steel wire 2 is less than the diameter of the sheath 12 of every pair of heart yearn 1 of parcel, the width both sides camber of novel steel wire indoor telephone line, and the radius of the arc of close steel wire 2 one sides is less than the radius of the arc of a side of close heart yearn 1.
As a more particular embodiment, the novel steel wire indoor telephone line of shape as shown in Figure 1, the described novel steel wire indoor telephone line wide 5.8mm in cross section, the high 2.2mm of highest point of the arc of close steel wire 2 one sides, the high 2.8mm of highest point of the arc of one side of close heart yearn 1, the diameter of heart yearn 1 is 0.5mm, and the diameter of steel wire 2 is 0.6mm, and the thickness of outermost sheath 3 is 0.5mm.
The above is only for the preferred embodiment of the invention; not in order to limit the invention; all in the invention spirit and principle within do any modification, be equal to and replace and improvement etc., all should be included within the protection range of the invention.
