The utility model discloses a telephone line, its simple structure is provided with the aluminium foil, can play fine shielding electromagnetic action, low in manufacturing cost, the high anti jamming ability can be put forward to the preferred adoption PE material of insulating layer, simultaneously can also be waterproof, anti -oxidation.
Description
Technical field
The utility model relates to a kind of transmission wire rod, more precisely, relates to a kind of four-core telephone wire.
Background technology
Telephone wire is generally for house wiring, its primary structure is the structure adopting one deck PVC oversheath at cable conductor outward, when this telephone wire is arranged in outdoor time, changeable due to weather, the moisture resistance of this telephone wire is poor, and easily receive the interference of external electromagnetic, thus have impact on the quality of call.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of four-core telephone wire.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of four-core telephone wire, comprises four heart yearns, and every root heart yearn comprises conductor and is positioned at the insulating barrier in outside, the axis of described four heart yearns is distributed in same circle circumferentially, and adjacent two heart yearns are tangent; Also comprise the aluminium foil of parcel four heart yearns, have sheath in the arranged outside of described aluminium foil.
Telephone wire of the present utility model, its structure is simple, is provided with aluminium foil, can plays and well shield electromagnetic action, low cost of manufacture; Insulating barrier preferably adopts PE material, can improve antijamming capability, simultaneously can also waterproof, anti-oxidation.
Accompanying drawing explanation
Fig. 1 shows the profile of the utility model telephone wire.
Embodiment
The technical problem solved to make the utility model, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further embodiment of the present utility model.
With reference to figure 1, the utility model provides a kind of four-core telephone wire, comprises four heart yearns, and every root heart yearn comprises conductor 1 and is positioned at the insulating barrier 2 in outside, and the axis of described four heart yearns is distributed in same circle circumferentially, and adjacent two heart yearns are tangent; Also comprise the aluminium foil 3 of parcel four heart yearns, have sheath 4 in the arranged outside of described aluminium foil 3.
Telephone wire of the present utility model, its structure is simple, is provided with aluminium foil, can plays and well shield electromagnetic action, low cost of manufacture; Insulating barrier preferably adopts PE material, can improve antijamming capability, simultaneously can also waterproof, anti-oxidation.
The utility model is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each execution mode with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of applicant has all dropped in scope that the utility model claim protects.
