A kind of superfine type six type unshielded data cable

Technical field

The utility model relates to a kind of data cables, and in particular to a kind of superfine type six type unshielded data cable.

Background technique

Cable, similar rope, usually by several or several groups of wire strandings form, mutually insulated between every group of conducting wire, and It is often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Cable has interior energization, the spy of external insulation Sign.Cable has power cable, control cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal cable, same Shaft cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc., they are all by sub-thread or stranded conductor and absolutely Edge layer composition, for connecting circuit, electric appliance etc..

Existing six type unshielded data cable has the following deficiencies: existing six type unshielded data cable, internal junction Structure is not compact, and transmission performance is poor, to reach transmission performance and meet national standard, and the nominal diameter 0.55mm of copper conductor~ 0.57mm, part manufacturer can accomplish national standard bottom line 0.55mm, and conductor line footpath is thick, at high cost, waste raw material.Six Type unshielded data cable is mainly used for the transmission of internal home network signal, and the outer diameter of cable is thick, is unfavorable for interior decoration cabling.

Summary of the invention

The utility model is not compact in order to solve existing six type unshielded data cable internal structure, and transmission performance is poor, It is thin, just to provide a kind of diameter for the technical issues of conductor line footpath is thick, at high cost, and outer diameter is slightly unfavorable for interior decoration cabling after stranding In the superfine type six type unshielded data cable of indoor cabling installation.

The utility model is equipped with it and is equipped with sheath thus, and cable core is equipped with inside sheath, and cable core is equipped with four groups of twisted pair wires and fills out Skeleton is filled, filling skeleton is the skeleton of section across, and cable core is separated into four spaces, is equipped with one group in each space Twisted pair wire, twisted pair wire are the conductors that two single lines are twist twisted into, and single line is interior to be equipped with copper conductor, be externally provided with insulating layer Conducting wire；It is characterized by: four groups of twisted pair wires are twist twisted in filling skeleton, twist and pitch is 110mm；The list of twisted pair wire Cabling pitch is the random length between 10mm~22mm.

Preferably, the twisting pitch of the single line of twisted pair wire is the random length between 10mm~16mm, and the copper in single line is led Body is that line footpath is 0.510mm~0.515mm.

Preferably, cable core is externally provided with twining package tape, for twisted pair wire described in four groups to be pressed in the slot that filling skeleton is formed, makes Cable core is more compact.

Preferably, filling skeleton uses LDPE Insulation Material, and filling skeleton was equipped with center framework and along the center framework week To four brackets for being uniformly distributed setting, bracket is tapered outward from center framework.

Preferably, the surface of adjacent two brackets and the surface of center framework form support cambered surface.

Preferably, tear rope is provided in sheath.

Technical solution disclosed by the utility model, compared with prior art, the superfine six class unmasked number of type of the utility model According to eight single lines in cable core in cable, twist twisted with the twisting pitch of random length between 10mm~22mm in pairs Synthesize four groups of twisted pair wires；Four groups of twisted pair wires are respectively placed in the slot that the different orientation of filling four, skeleton is formed, to twist and save It is twist twisted away from 110mm, twining package tape is wrapped on the outside of cable core.It fills skeleton and is equipped with center framework and along center framework circumferential direction Four brackets of setting are uniformly distributed, bracket is tapered outward from center framework, and filling skeleton surface generates outside pressure Act on twisted pair wire；Twining package tape is wrapped on the outside of cable core, is generated inward pressure and is acted on twisted pair wire；Fill skeleton structure with The cooperation of twining package tape is so that compact-sized stabilization, the cross-sectional area of the Rational Arrangement of four groups of twisted pair wires, cable core are small and round in cable core It is whole.Sheath guarantees the stable structure of cable core, prevents the external force in laying and use process, avoids the knot for influencing cable core Structure.A tear rope is added inside sheath, and worker is facilitated to carry out construction usage.

Optimized by above-mentioned cable core structure, under the premise of product transmission performance is that meet national standards, is used in single line 24AWG 0.510mm~0.515mm line footpath copper conductor replaces 23AWG0.570mm line footpath copper conductor in traditional handicraft, reduces copper Conductor line footpath realizes the saving to copper conductor material, and notebook data cable items mechanical performance is superior, and structure is simple, copper Conductor dosage is adjusted downward to present 15.63kg/km by traditional processing technology 18.37kg/km, and every kilometer can save copper material 2.74 Kilogram；And six type unshielded data cable outer diameter is adjusted by 6.6mm to 5.7mm, is suitble to construction and installation.
