Abstract
The invention discloses a kind of closing-type windable aluminum metal set multi-functional cable, including some insulated wire cores, it is a stranding that those insulated wire cores are stranded, each insulated wire cores include a conductor and an insulating barrier, the outer surface of the stranding extrudes an aluminium set, and the twisting pitch of the insulated wire cores is identical with the pitch of the aluminium set.By directly extruding an aluminium set on the outside of stranding, on the one hand the consuming of packing material is reduced, on the other hand, external diameter reduces aluminium set in itself, and consumptive material is less, aluminium set length is cable length, linear resistance is small, and contact of the aluminium set with cable conductor becomes cambered surface by wire, is no longer completely cut off by air, radiating effect is greatly improved, and its current capacity has also strengthened.
Description
Technical field
The present invention relates to a kind of closing-type windable aluminum metal set multi-functional cable.
Background technology
The multicore fireproof cable supplied in the market, most unitary function, seldom simultaneously have concurrently protection against rodents, ant proof, waterproof,
Resistance to compression and the function of electromagnetic shielding.And the metal sheathed cable manufactured using traditional handicraft, needed first by stranding gap during stranding
Filling rounding, then extrude corrugated aluminum sheath.
As shown in figure 1, existing cable can form crest and trough due to corrugated aluminium sheath, there is sky between crest and trough
Gas is present, and is in contact with a spiral helicine line between trough and insulating barrier 10 and packing material 20, therefore aluminum metal set 30
It is among the isolation of air 40 with the extreme portions of cable core, because the thermal resistivity of air is bigger than the thermal resistivity of plastic insulation
100-1000 times or so so that cable heat dispersion is deteriorated, (after the conductive section and material of cable determine, cable has
Effect current capacity depends primarily on the quality of external heat dispersion) so that the current capacity of cable decreases.
Additionally, when corrugated aluminium sheath is extruded, corrugated aluminium sheath is more more than the aluminium set consumptive material of flat, increased the linear of aluminium set
Resistance, the outside diameter of cable is also larger, need to take and more lay space.
The content of the invention
The technical problem to be solved in the present invention is to overcome that cable thermal diffusivity in the prior art is poor, external diameter is big, consumptive material is more, carry
The low defect of stream ability, so as to provide a kind of cost performance closing-type windable aluminum metal set multi-functional cable higher.
The present invention is to solve above-mentioned technical problem by the following technical programs：
A kind of closing-type windable aluminum metal covers multi-functional cable, and its feature is, including some insulated wire cores, and those are exhausted
It is a stranding that edge core is stranded, and each insulated wire cores include a conductor and an insulating barrier, and the outer surface of the stranding extrudes an aluminium
Set, the twisting pitch of the insulated wire cores is identical with the pitch of the aluminium set.
In this programme, the good multiple insulated wire cores outside of stranding is directly extruded into one layer of aluminium set, without filling, by rolling
Be squeezed in aluminium set on the surface of insulated wire cores by pressure technique, is allowed to be close to insulated wire cores, that is, be close to the outline of insulated wire cores, by
It is close to insulated core surface in aluminium set, space is there's almost no between insulated wire cores and aluminium set, also just hardly there is air,
Therefore cable heat dispersion enhancing.Aluminium set per se with insulated core identical pitch, changed the bending property of cable
It is kind.The whole construction of cable is compact, and diameter is smaller.Because heat dispersion is improved, therefore, the current-carrying capacity of cable also can be improved accordingly.
The cable is provided simultaneously with the functions such as fire prevention, protection against rodents, ant proof, waterproof, resistance to compression and electromagnetic shielding.When aluminium set design section
Resistance and cable earth wire core section resistors match when, you can used as ground wire.
It is preferred that the aluminium set includes being close to arc section and connection arc section with the insulated wire cores quantity identical, often
One is close to arc section fits with the outer peripheral face of each insulated wire cores, it is each connection arc section positioned at adjacent two be close to arc section it
Between.
Positive effect of the invention is：By directly extruding an aluminium set on the outside of stranding, on the one hand reduce and fill out
The consuming of material is filled, on the other hand, external diameter reduces aluminium set in itself, and consumptive material is less, and aluminium set length is cable length, linear resistance
Small, contact of the aluminium set with cable conductor becomes cambered surface by wire, is no longer completely cut off by air, and radiating effect is greatly improved, its current-carrying
Ability has also strengthened.
Brief description of the drawings
Fig. 1 is the structural representation of existing cable of the invention.
Fig. 2 covers the structural representation of multi-functional cable for the closing-type windable aluminum metal of one embodiment of the invention.
Fig. 3 is the structural representation of rolling aluminium set in Fig. 2 of the present invention.
Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to described reality
Apply among a scope.
The present embodiment provides a kind of closing-type windable aluminum metal set multi-functional cable, as Figure 2-3, including 3 exhausted
Edge core, it is a stranding that those insulated wire cores are stranded, and each insulated wire cores include a conductor 1 and an insulating barrier 2, the appearance of stranding
Face extrudes an aluminium set 3, and the twisting pitch of insulated wire cores is identical with the pitch of aluminium set 3.
Wherein, aluminium set 3 including 3 be close to arc section 31 and 3 connection arc sections 32, it is each be close to arc section with it is each absolutely
The outer peripheral face of edge core is mutually close to, and each connection arc section is close between arc section positioned at adjacent two.
The closing-type windable aluminum metal set multi-functional cable of the present embodiment changes traditional handicraft, no longer than cable core
The aluminium set of the big 10~15mm of external diameter rolls into the waveform risen and fallen regularly, but the aluminium set of external diameter is equal to cable core, is extruding
Use rolling tools roll forming afterwards, its rolling pattern as shown in figure 3, in Fig. 3 reference 4 represent rolling tools, wherein, roller
Quantity is identical with cable core number, circumferentially decile, and rolling is implemented to the hole between aluminium set and cable core, and existing cable is herein
It is packing material, because the cable core of cable carries spiral helicine pitch in stranding, therefore the aluminium set for having rolled is with identical
Helical form pitch.Aluminium set becomes curl from flat, with reelability.
Therefore, the present embodiment, can be while packing material be reduced by directly extruding an aluminium set on the outside of stranding
Cable external diameter in itself reduces, and consumptive material is less, and aluminium set length is cable length, and linear resistance is small, aluminium set and cable conductor
Contact becomes cambered surface by wire, is no longer completely cut off by air, and radiating effect is greatly improved, and its current capacity can also strengthen.
Although the foregoing describing specific embodiment of the invention, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
On the premise of principle of the invention and essence, various changes or modifications can be made to these implementation methods, but these are changed
Protection scope of the present invention is each fallen within modification.
