Description

The four-core ribbon cable of a kind of band control cable core

Technical field

The utility model belongs to field of cables, particularly the four-core ribbon cable of a kind of band control cable core.

Background technology

Along with the universal develop rapidly with information industry of computer technology, Intellectual district has become the development trend of modern architecture, by the comprehensive wiring system that is made up of compound 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 complete supporting entirety, to realize highly intelligentized requirement.

The four-core compound cable of the band control cable core of prior art, usual structure is by stranded to control cable core and four circular cores being extruded with insulation, or four fan-shaped cores are stranded rear stranded with control cable core. Quad core comprises the identical fourth class core in four conductor cross sections or three 3+1 cores that conductor cross section is big, a conductor cross section 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 easily channels bit, usually add packing material stranded together, and time stranded, skin need to be tightened with band for this reason, stranded or become after cable to extrude sheath again. The four-core compound cable of this structural band control cable core, not only cable core stability is poor, and material usage is big, also add cable weight and cost. As adopted four stranded fan-shaped line cored structures, although cable core stability improves, but core is processed into sector structure, processes round core complicated, needs strict control fan angle and fan-shaped height, and the phenomenons such as in uneven thickness, insulation layer splits easily occurs; Secondly, being no matter the four-core compound cable of the band control cable core of which kind of stranded form, lay configuration makes actual core length increase, waste material, increase weight, the increase of cable cost; Again, this structure also makes the outside diameter of cable relatively big, especially large gauge cable, and big external diameter not only increases manufacture, transport difficult, and takies that to lay space big. Besides, the compound 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 conducive to reducing electric energy loss. But the outside diameter of cable of this kind of structure still very greatly, highly high, when laying in wire casing, when especially needing multi-cable simultaneously overlap is laid, take that to lay space still very big, small space limit use; Secondly, many circular cables together laying installation time, be easily wound around between cable, and identify difficulty, it may also be useful to troublesome maintenance; Again, circular cable core identification difficulty, particularly four uniform cross section conductors, it is necessary to every root core all identifies; Besides, when using circular cable, due to the feature on its structure, the torsional moment of whole cable is made to be zero more difficult, a lot of occasion uses cable also to need repeatedly to move, 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, under cable endlap add bear above discharge the twisting resistance that transmits, therefore twisting resistance is maximum, and the distortion that therefore can be distorted after the use several months, bulge, broken skin are 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 work-ing life. Therefore the place being worth improvement is still had.

In prior art, there is the structure adopting flat cable, it is possible to repeatedly move, bend, or vertically use, mobile with, in BENDING PROCESS, power cable core and control cable easily produce relative movement, rub and produce heat and damage covering.

Practical novel content

The utility model is the shortcoming overcoming prior art existence, provide the four-core ribbon cable of a kind of band control cable core, fill insulation filler in space between the power cable core of this cable and control cable core, it is possible to the friction between buffering power cable core and control cable core, extend cable work-ing life.

The four-core ribbon cable of a kind of band control cable core disclosed in the utility model, comprise the power cable core directly dragged side by side and control cable core, it is surrounded by total foreskin at power cable core and control cable core, filling insulation filler in space between power cable core and control cable core, described insulation filler comprises soft plastics or fibers material; Three phase cores are directly dragged at described power Lan Xin center side by side, at the peripheral arrangement some wire core conductors side by side of three phase cores, extrude total sheath outside wire core conductor.

Further, between described three phase cores and wire core conductor, the first insulation layer is set.

The improvement of another kind one, the conductor that described phase core is made up of some monofilament and wrapped the 2nd insulation layer at conductor form.

The improvement of another kind one, described wire core conductor diameter is identical with filament diameter.

The improvement of another kind one, wire core conductor is solid naked round conductor, or for extruding the filled circles conductor of insulation.

Another planting an improvement, wrapped metal screen layers after described control cable core is stranded by some control conductor, outside extrudes sheath again and becomes.

The improvement of another kind one, described control conductor quantity is 2 or more than 2.

Another planting an improvement, described control conductor is by control conductor conductor and is extruded in the 3rd insulation layer outside control conductor conductor and forms.

The improvement of another kind one, the external diameter of described control cable core is identical with the height of power cable core.

The four-core ribbon cable of a kind of band control cable core disclosed in the utility model, it is possible to transferring electric power and control signal simultaneously, and independent mutually. Phase core, wire core, control cable core are all directly dragged, and save packing material and band, decrease the waste of material of stranded increase length, alleviate weight. Flat shape structure, it is possible to repeatedly move, bend, or vertically use. Insulant is filled, it is possible to mutual motion between dash-control cable core and power cable core and friction between control cable core and power cable core. Owing to there being the existence of control cable core, it is not necessary to identify phase core, wire core, namely can differentiate whole phase core, wire core, can not be wound around, identify between cable easily, it may also be useful to easy to maintenance. Flat shape, highly more circular low, and wire core is divided into some independent conductors, and become flat shape to be arranged in outside three phase cores arranged side by side side by side, arrangement is short side by side simultaneously compared with four-core for width, reduces and lays space, easy construction. The flat shape of wire core is arranged in outside three phase cores arranged side by side side by side; the phase core undertaking power transmission is made to be positioned at innermost layer; it is possible not only to the effect playing similar steel wire armor; phase cable core can be played a very good protection; effectively alleviate and damage by external force; but also shielding effect can be played, effectively reduce the electromagnetic interference of control cable core and surrounding electric installation, and extraneous electromagnetic interference.
