Abstract
The utility model discloses a twisted-pair telephone leading-in wire, comprising a transmission matrix coated with an insulator, as well as a carrier, wherein the transmission matrix and the carrier are coated with black polrvinyl chloride, the black polrvinyl chloride has a dumbbell shape, one end of the black polrvinyl chloride contains the transmission matrix, and the other end contains the carrier; the transmission matrix adopts two 0.65mm oxygen-free copper rods; and the carrier adopts a 1.2mm galvanized steel wire. The twisted-pair telephone leading-in wire has the beneficial effects that: a carrying structure is utilized, the leading-in wire is especially suitable for large-span long-distance communication transmission requirements in varied terrain, and is suitable to be used in flat areas such as in city, and the versatility is strong; further the twisted-pair telephone leading-in wire has the advantages of good transmission performance, strong stability, long service life, easy separation of the transmission matrix and the carrier, convenient operation, and high working efficiency.
Description
Technical field
The utility model relates to a kind of multiple twin formula phone lead-in.
Background technology
In the prior art, the phone lead-in nearly all is to adopt the irony parallel lines of insulation promptly to form its not only load-bearing but also transmission signals by the multiple two parallel iron core leads of insulator bag; Though this lead-in is simple in structure, transmission performance is poor, and transmission range is restricted; Can not adapt to various telephone service needs, build with use in many inconvenience are all arranged, it is more concentrated especially to work as user offline; Need draw several during simultaneously to parallel lines; Operating difficulties, the line that more is inappropriate for free wiring mode is inappropriate for totally-enclosed continuing to drawing.
The utility model content
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of multiple twin formula phone lead-in to be provided, and is simple in structure, transmission performance good, stability is strong, long service life.
The technical scheme that realizes above-mentioned purpose is:
A kind of multiple twin formula phone lead-in comprises the transmission parent that is coated with insulator, and supporting body; Said transmission parent and supporting body are coated with black pvc; Said black pvc is dumbbell shaped, and an end comprises the transmission parent, and the other end comprises supporting body.
Said transmission parent adopts two oxygen-free copper bars.
Said carrying parent diameter is 0.65mm.
Said supporting body adopts zinc-coated wire.
Said supporting body diameter is 1.2mm.
The beneficial effect of the utility model multiple twin formula phone lead-in: adopt unitary construction, it is changeable to be specially adapted to landform, and big span long haul communication transmission requirement is also used highly versatile applicable to area, level lands such as city.And transmission performance is good, strong, the long service life of anti-stability, and its transmission parent and supporting body are easily separated, easy to operate, high efficiency.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model multiple twin formula phone lead-in.
Embodiment
In order to understand the technical scheme of the utility model better, below through concrete embodiment and combine accompanying drawing at length to explain:
See also Fig. 1; The multiple twin formula phone lead-in of the utility model embodiment comprises the transmission parent 1 that is coated with insulator 4; And supporting body 2, said transmission parent 1 is coated with black pvc 3 with supporting body 2, and said black pvc 3 is dumbbell shaped; One end comprises transmission parent 1, and the other end comprises supporting body 2.
Said transmission parent 1 adopts two 0.65mm oxygen-free copper bars, and transmission performance is strong.The insulator 4 that transmission parent 1 outside coats is high density polyethylene (HDPE) (HOPE), and insulation thickness reaches 0.8mm, has solved the excessive problem of long Distance Transmission signal attenuation, also makes the transmission stability of phone lead-in and durability become stronger simultaneously.
Said supporting body 2 adopts the zinc-coated wire of 1.2mm, has solved weakness such as ordinary steel wire is perishable, oxidation, the zinc-coated wire longer service life.
The black pvc 3 (PVC) of transmission parent 1 and the coating of supporting body 2 outsides, uvioresistant is strong, and weatherability is strong, uses out of doors, and its ageing resistace is superior, and service life is long.Black pvc 3 is dumbbell shaped, two head breadths, and intermediate narrower, that part of structural design of intermediate narrower can be introduced easier separated transmission parent and supporting body in the first use at phone, simplifies construction, and handled easily increases substantially operating efficiency.
The multiple twin formula phone lead-in of the utility model adopts unitary construction, and it is changeable to be specially adapted to landform, and big span long haul communication transmission requirement is also used highly versatile applicable to area, level lands such as city.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
Claims (5)
