Description
Technical field
The present invention relates to electric wire field, the especially a kind of compound flat cable that blocks water of five cores.
Background technology
Five-core cable in the prior art, usual structure are that the circular core for being extruded with five insulation is twisted, or four
Root segment conductor-core is twisted with a circular core.Five-core cable core includes five identical grade cores of five cross-sectional area of conductor, and three are led
Body section is big, two cross-sectional area of conductor are small " three big two is small " core or four cross-sectional area of conductor are big, a cross-sectional area of conductor is small, and " four is big by one
It is small " core.Five circular cores are twisted particularly five unequal section circle cores and are twisted, and core gap is larger, not only so that electricity
Cable roundness is poor, and easily loose during extruding and constructing etc., and core easily channels bit, and is usually added into for this
Packing material is twisted together, and it is twisted when outer layer need to be tightened with band, be twisted or stranding after extrude sheath again.This structure five
Core cable, not only cable core stability is poor, but also material utilization amount is big, also add cable weight and cost.It is such as twisted using five
Segment conductor-core structure, although cable core stability improves, core is processed into sector structure, processes relatively round core complexity, needs stringent
Segment angle and fan-shaped height are controlled, and phenomena such as in uneven thickness, insulating layer splits easily occurs；Secondly, either which kind of
The five-core cable of twisted form, lay configuration so that actual core length increase, waste of materials, increase weight, cable cost increase
Greatly；Again, this structure also make it that the outside diameter of cable is larger, especially big specification cable, and big outside diameter not only increases manufacture, transport
Difficulty, and it is big to take laying space.Besides, the five-core cable electromagnetic interference of usual structure is larger.
The prior art circular configuration outside diameter of cable is big, is laid in wire casing, especially needs multi-cable is overlapping at the same time to apply
If when, take laying space still very greatly, use is limited in small space；Secondly, more round cables lay peace together
During dress, easily wound between cable, and identify difficult, working service trouble；Again, the identification of round cable core is difficult, especially
It is five cross-section conductors, it is necessary to which every core is identified；When besides, using round cable, due to it structurally
Feature, the torsional moment that make whole cable are zero to be more difficult to, and many occasions are also needed to move repeatedly, bent using cable, or
Torsion vertical to use, that when torsion and manufacture of cable itself adds, and installation do not pay attention to increased torsion, especially vertical
In use, cable lower superposition bears to discharge the twisting resistance transmitted above, therefore twisting resistance is maximum, therefore after using the several months
Can be distorted deformation, bulge, broken skin, until fractureing cored wire.These not only easily trigger accident, cause cable short circuit or damage to set
It is standby；And cable service life is caused to shorten.Therefore still there is worth improved place.
In the prior art, there is the structure using flat cable, although it can move repeatedly, bend, or vertical use,
Five cores are arranged in parallel at the same time, add the length of cable, and structure is not compact；And existing cable block-water performance is poor, heat dissipation
Poor performance, causes cable easily to generate heat spontaneous combustion.
The content of the invention
The present invention is to overcome shortcoming existing in the prior art, there is provided one kind can be moved repeatedly, bends, vertically used,
Compact-sized, outside diameter is small, and easy to process and convenience is constructed, block-water performance is good, perfect heat-dissipating five cores composite fire-proof flat cable.
To solve above technical problem, a kind of compound flat cable that blocks water of five cores of the present invention, which is flat knot
Structure, cable center are equipped with three insulated wire cores directly dragged side by side, and some wire cores of laid out in parallel half-turn are led outside insulated wire cores
Body and the neutral cores of some of half-turn, ground wire core conductor and neutral core overcoat set flat and block water hose, ground wire core conductor, neutrality
The gap filling water blocking yarn that core and flat block water between hose, flat block water and extrude polyurethane water-proof oversheath outside hose,
Slot is provided with polyurethane water-proof oversheath, the filling heat absorption cotton in slot.
By aluminium alloy conductor and outside aluminium alloy conductor, non-woven fabrics is formed the insulated wire cores.
The neutral core is by aluminium conductor and is extruded in steel band shielded layer outside aluminium conductor and forms.
Ground wire core conductor gap arrangement equidistant with neutral core is covered with the side of insulated wire cores periphery, two
Person's quantity is identical.
The ground wire core conductor and the diameter and the diameter phase of the copper monofilament of composition ground wire core conductor of neutral core
Together.
Beneficial effect of the present invention is：
Compared with prior art, five core flat cables of the invention, insulated wire cores, neutral core, wire core directly drag, save and fill out
Material and band are filled, reduces the waste of material of twisted increase length, alleviates weight；Squashed structure, can move repeatedly, is curved
Song, or vertical use；As long as identify any one phase core, you can to differentiate whole cores；It will not wind, between cable
Identification is easy, and working service is convenient；Flat, height is more circular low, and wire core is divided into some independent conductors, into flat simultaneously
Row are arranged in outside two phase cores arranged side by side, and laid out in parallel is short at the same time compared with five cores for length, reduces laying space, easy for construction；
Wire core flat laid out in parallel makes the insulated wire cores for undertaking power transmission be located at innermost layer, no outside three phase cores arranged side by side
It can only play the role of similar steel wire armoured, can play a very good protection to phase cable core, effectively mitigate by external force
Damage, and shielding action is may also function as, the electromagnetic interference to electrical equipment around is effectively reduced, and extraneous electromagnetic is done
Disturb；Using hose and the polyurethane water-proof outer jacket structure of blocking water so that cable has a double-deck water stop function, substantially increases
The block-water performance of cable；Slot is provided with polyurethane water-proof oversheath, the filling heat absorption cotton in slot so that cable has very
Good heat dissipation performance, will not occur dieseling.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
