Abstract

The utility model discloses a compact four -core ribbon cable can simultaneous transmission electric power and control signal, just independence of each other. This cable is including being located the power cable core of intermediate position, and control core in power cable core space contains two control core, crowded metal encapsulated insulating layer outside control core among the every control cable core. This cable structure is compact, and the external diameter is little, and occupation space is few, and can remove repeatedly, crookedly, perpendicular use, easily process and make things convenient for the construction.

Description

A kind of Compact four-core ribbon cable

Technical field

This utility model belongs to field of cables, particularly a kind of Compact four-core ribbon cable.

Background technology

Along with popularizing of computer technology and developing rapidly of information industry, Intellectual district has become the development trend of modern architecture, by the comprehensive wiring system that is made up of composite cable etc. the communication in intelligent construction, computer and various equipment and facility, include comprehensive wiring system under certain conditions in, it is interconnected to form completely supporting entirety, to realize highly intelligentized requirement.

The Compact four-core ribbon cable with control conductor of prior art, usual structure is by stranded to control cable core and four circular cores being extruded with insulation, or four segment conductor-cores are stranded rear stranded with control cable core.Quad core includes four identical fourth class cores of cross-sectional area of conductor or three 3+1 cores that cross-sectional area of conductor is big, a cross-sectional area of conductor is little.No matter it is the stranded of which kind of form, core gap is bigger, not only make cable roundness poor, and extrude and in the process such as construction easily loose, and core is susceptible to channel bit, it is usually added into packing material for this stranded together, and time stranded, outer layer need to be tightened with band, stranded or after stranding, extrude sheath again.This structure four core composite cable, not only cable core poor stabilities with controlling cable core, and material usage is big, also add cable weight and cost.As adopted four stranded segment conductor-core structures, although cable core stability improves, but core is processed into sector structure, process relatively round core complicated, need to strictly control segment angle and fan-shaped height, and the phenomenons such as in uneven thickness, insulating barrier splits easily occur；Secondly, it is no matter the four core composite cables with controlling cable core of which kind of stranded form, lay configuration so that actual core length increases, waste material, increase weight, cable cost increase；Again, this structure also makes the outside diameter of cable relatively big, especially big specification cable, and big external diameter not only increases manufacture, transport difficult, and takies that to lay space big.Besides, the composite cable power wire core of usual structure is bigger to the electromagnetic interference of control conductor.

Adopt circular shape concentric structure, it is possible to reduce the outside diameter of cable, reduce the waste of material of stranded increase length, alleviate weight, not only reduce and account for deposited space, easy construction, and reduce cost, be also beneficial to reduce electric energy loss.But the outside diameter of cable of this structure still very greatly, highly high, when laying in wire casing, when especially needing multi-cable simultaneously overlap to lay, take that to lay space still very big, small space limit use；Secondly, during many round cable laying installations together, being easily wound around between cable, and identify difficulty, working service bothers；Again, round cable core identification difficulty, particularly four uiform section conductors, it is necessary to every core is all identified；Besides, when using round cable, due to its constructional feature, making the torsional moment of whole cable is zero be more difficult to, a lot of occasions use cable to also need to move repeatedly, bend, or vertically use, the torsion added when the torsion of cable self and manufacture, and the torsion not noting increasing is installed, especially when vertically using, the superposition of cable lower end is born and is discharged the twisting resistance transmitted above, therefore twisting resistance is maximum, is therefore using the deformation that can be distorted after the several months, bulge, broken skin until the heart yearn that fractures.These are not only easily accidents caused, cause cable short circuit or damage equipment；And cause cable shortening in service life.Therefore the place being worth improvement is still had.

In prior art, there is the structure adopting flat cable, although can move repeatedly, bend, or vertically use, but four cores are simultaneously arranged in parallel with control cable conductor, add the width of cable, and structure is not compact.

Utility model content

This utility model is the shortcoming overcoming prior art to exist, it is provided that can transmitting electric power and control signal, compact conformation the while of a kind of, external diameter is little simultaneously, and can move repeatedly, bend, vertically use, be prone to the Compact four-core ribbon cable of processing and convenient construction.

The disclosed a kind of Compact four-core ribbon cable of this utility model, including a kind of Compact four-core ribbon cable, including power cable core, three phase cores are directly dragged at described power cable core center side by side, extrude total sheath outside three phase cores；Arranging in the space of power cable core some control conductor, every controls to comprise two control conductor in cable core, at the outer wrapped lapping layer of each control conductor, jointly extrudes metal dielectric layer outside the lapping layer of two control conductor again.

Further, described control conductor has four, is individually positioned in four spaces that three phase cores are formed.

Another kind of improvement, the conductor that described phase core is made up of some monofilament and the total jacket being extruded in conductor form.

A kind of Compact four-core ribbon cable of the present utility model, it is possible to transmission electric power and control signal simultaneously, and independent mutually.Phase core, wire core are all directly dragged, and save packing material and band, decrease the waste of material of stranded increase length, alleviate weight.Squashed structure, it is possible to move repeatedly, bend, or vertically use；As long as identifying any one phase core, whole core namely can be differentiated；Will not be wound around, between cable, identify that easily, working service is convenient.Flat, highly more circular low, control cable and be arranged in the space of power cable, laid out in parallel is short simultaneously compared with four cores for length, reduces and lays space, easy construction.

Accompanying drawing explanation

Fig. 1 is the disclosed a kind of Compact four-core ribbon cable structural representation of this utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.

As it is shown in figure 1, a kind of Compact four-core ribbon cable, including power cable core, three phase cores 2 are directly dragged at power cable core center side by side, extrude total sheath 1 outside three phase cores 2；Four root control conductor 3 of arrangement in four spaces of power cable core, every controls to comprise two control conductor 32 in cable core 3, and at the outer wrapped lapping layer 31 of control conductor, the lapping layer 31 of two control conductor 32 is outer extrudes metal dielectric layer 33 more jointly.

The conductor that phase core 2 is made up of some monofilament 22 and the insulating barrier 21 being extruded in outside conductor form.

The concrete application approach of this utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model principle; can also making some improvement, these improvement also should be regarded as protection domain of the present utility model.
