Abstract

The cable comprises lines, a network line, an electric power line, which are enwrapped and coplanar arranged in order, wherein the wire wrapper which is a thermoplastic plastics, for example polyvinyl chloride, enwraps the three lines via covering-extrusion process, thus integrating the telephone line, the network line and the electronic power line. Comparing with the prior art, the cable in the utility integrates the three lines, then the three lines are enwrapped by a coating for protection, and the cable is platy, has a surface contact with the wiring groove, therefore the cable will not be damaged even under a larger pressure, the cable has a long lifespan.

Description

The wiring cable

[technical field]

The relevant a kind of wiring cable of the utility model, refer in particular to a kind of coat multiple wire rod and can bear bigger ambient pressure the wiring cable.

[background technology]

In the present society, information increases progressively with geometric progression, information interchange has become people's study, work, even important contents during amusement, therefore message transmission just becomes very important, and wire communication becomes the main flow mode of message transmission with its high transfer rate, high stability and low error rate, and wire communication just be unable to do without the communication cable as transmission medium.

Cable in the modern office environment comprises grid line, telephone wire and power line at least, and because grid line, telephone wire and power line are the wire rod that independently separates, toughness and intensity are not high, in case suffer the as easy as rolling off a log damage of external force, therefore conventional occupation mode is that three kinds of cables are located in the wiring groove, changes cable as need, this wiring groove must be taken apart, install former wiring groove after to be replaced again or increase by a wiring groove, so not only increased cost but also take up room, for the user makes troubles.

In view of this, be necessary to develop a kind of wiring cable that coats multiple wire rod and can bear bigger external force in fact.

[summary of the invention]

Therefore, the purpose of this utility model promptly provides a kind of wiring cable that coats multiple wire rod and can bear bigger external force.

For reaching above-mentioned purpose, wiring cable of the present utility model is made up of be wrapped outward telephone wire, grid line, the power line arranged according to this roughly in the same plane, wherein, should outer quilt be the thermoplastic plastic, polyvinyl chloride for example, it is above-mentioned three-way to utilize the coating extrustion process to be coated on, so that this telephone wire, grid line, power line are gathered together.

Compared with prior art, coat one deck after wiring cable of the present utility model gathers together three kinds of wirings and be used as protective layer outward, and be offset flat shape; with wiring groove is that face contacts; it is bigger to bear extraneous pressure, also is difficult for being damaged longer service life by extraneous.

[description of drawings]

Fig. 1 is the section structure schematic diagram of an embodiment of wiring cable of the present utility model.

[embodiment]

As shown in Figure 1, section structure schematic diagram for wiring cable of the present utility model, wherein, outward by 10 parcels telephone wire 11, grid line 12, the power line 13 arranged according to this roughly in the same plane, wherein, this is thermoplastic plastic, for example polyvinyl chloride by 10 outward, it is above-mentioned three-way to utilize coating extrustion process (extrusion coating) to be coated on, so that this telephone wire 11, grid line 12, power line 13 are gathered together.

Please continue with reference to Fig. 1, this telephone wire 11 is formed in order to receive with the holding wire 111 that transmits signal respectively by crust 110 parcel two, and this binary signal line 111 is made up of the first conductor 111a and the second insulating barrier 110b that is coated on this first conductor 111a.

This grid line 12 adopts 2 to (4 core) twisted-pair feeder 120, its insulation sheath 121 coats 2 pairs of twisted pair wires 120, this twisted pair wire 120 is formed by the 122 mutual stranded entanglement of two heart yearns, wherein, the insulator 122b that this two heart yearn 122 comprises solid conductor 122a and wraps up this solid conductor 122a, and load positive signal and negative signal respectively on this two solid conductor 122a, utilize the pair twist characteristic to reduce the cross-talk between this two twisted pair wire 120.

Adopt 4 to (8 core) twisted-pair feeder compared to the standard Category-5 twisted pair that generally uses at present; wherein; only need use two pairs in actual the use; the a pair of transmission signals that is used for; another is to being used for received signal; other two couple is the extra pairs of above-mentioned two pairs of twisted-pair feeders when being destroyed, and has of the present utility modelly been had defencive function by 10 structural designs that coat these grid lines 12 outward, has therefore cancelled this extra pair.

The live wire of this power line 13 (hot) 131, ground wire 132, zero line (neutral) 133 are roughly in the same plane, and it coats the second conductor 13a extrusion moulding by the second insulating barrier 13b respectively.

This wiring cable is when extruding, make this telephone wire 11, grid line 12 and power line 13 together in company with being extruded in nib by 10 outward, make outside this to be filled between the above-mentioned three, and then telephone wire 11, grid line 12 and power line 13 are alongst combined by 10.

Compared to existing circular net winding thread, power line, it is that line contacts and easily presses partially and destroyed with wire casing, Wiring cable of the present utility model will at least three kinds the wirings rear coating one deck that gathers together be used as protection outward Layer, and be offset flat shape, be that face contacts with wiring groove, it is bigger to bear extraneous pressure, also is difficult for by extraneous Damage longer service life; In addition, once wiring namely has the several functions requirement, neat appearance, simple side Just.

Claims

1, a kind of wiring cable is characterized in that: this wiring cable is formed by coating independent wire rod outward.

2, wiring cable as claimed in claim 1 is characterized in that: this independent wire rod is respectively telephone wire, grid line, power line.

3, wiring cable as claimed in claim 1 is characterized in that: this is outer to be the thermoplastic plastic, and is coated on this telephone wire, grid line, power line with the coating extrustion process.

4, wiring cable as claimed in claim 1 is characterized in that: this grid line adopts 2 pairs of i.e. 4 core twisted-pair feeders.
