Description
Technical field
Field of cable technology is the utility model is related to, specifically a kind of ethylene propylene rubber insulated type electric wire.
Background technology
Cable uses more universal in daily life, is brought great convenience for the life of people.It is existing
Some cables are often easily bent and pulled drawing during use, the time one grow easily cause cable skin breakage or
Fracture inside person's cable, cause normally to use, once break down, it is necessary to be examined to whole electric wire
Repair, this service work is time-consuming longer, seriously affects actual production and life, therefore there is an urgent need to a kind of new good toughness
Cable.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of ethylene propylene rubber insulated type electric wire.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of ethylene propylene rubber insulated type electric wire, including proof copper-wire braided screen layer, be extruded in outside proof copper-wire braided screen layer
The sheath of side, sheath is provided with the proof copper-wire braided screen layer, the sheath is enclosed with cable core.
The cable core includes interior cushion and four strands of ethylene propylene rubber insulated cores, four strands of ethylene propylene rubber insulated core folders
It is twisted on the outside of interior cushion and together and forms cable core.
The interior cushion includes central buffer tube, symmetrical centered on central buffer tube and be arranged in adjacent two
Side separator tube between individual ethylene propylene rubber insulated core.
The central buffer tube, side separator tube are hollow rubber flexible pipe.
The inner surface setting of the sheath has four to correspond to respectively with four strands of ethylene propylene rubber insulated cores to engage and into spiral shell
Revolve the arc pad of shape distribution.
The inside of the arc pad is provided with cushion chamber.
The ethylene propylene rubber insulated core includes conductor, the ethylene propylene rubber insulated layer being extruded on the outside of conductor.
The sheath is made up of the elastomeric material of good toughness.
The beneficial effects of the utility model are：The utility model has that reasonable in design, manufacturing cost is low, service life
The advantages that long and good toughness, good protective effect can be served to core using interior cushion；The structure design of sheath,
Be effectively prevented the twisting of cable core in use, effectively prevent cable during the use of reality bending or
The phenomenon being broken during drawing is pulled, so as to the service life of the cable of extension, can ensure that instrument normal work.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is internal structure schematic diagram of the present utility model；
Fig. 2 is the structural representation after being splitted along axis of sheath of the present utility model；
Fig. 3 is the structural representation along after being splitted perpendicular to axis of sheath of the present utility model.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
It is expanded on further in face of the utility model.
As shown in Figure 1 to Figure 3, a kind of ethylene propylene rubber insulated type electric wire, including proof copper-wire braided screen layer 7, be extruded in
The sheath 8 in the outside of proof copper-wire braided screen layer 7, sheath 1 is provided with the proof copper-wire braided screen layer 7, the sheath 1 wraps up
There is cable core.Good protective action can be played to cable core by sheath 1.
The cable core includes interior cushion and four strands of ethylene propylene rubber insulated cores, four strands of ethylene propylene rubber insulated core folders
It is twisted on the outside of interior cushion and together and forms cable core.
The interior cushion includes central buffer tube 6, symmetrical centered on central buffer tube 6 and be arranged in adjacent
Side separator tube 5 between two ethylene propylene rubber insulated cores.The utility model is matched somebody with somebody by central buffer tube 6 and side separator tube 5
Close, so as to which during electric cable transporting, use, four strands of ethylene propylene rubber insulated cores can be played with the work of good isolating and protecting
With avoiding direct friction between four strands of ethylene propylene rubber insulated cores and cause to crush, the generation of phenomenon of rupture, make so as to extend
Use the life-span.
The central buffer tube 6, side separator tube 5 are hollow rubber flexible pipe, and the utility model uses hollow rubber flexible pipe,
So as to improve the performance of buffer protection.
The inner surface setting of the sheath 1 has four to correspond to respectively with four strands of ethylene propylene rubber insulated cores to engage and into spiral shell
Revolve the arc pad 2 of shape distribution, the utility model design arc pad 2, four strands of ethylene propylene rubber insulated cores that can be after strand
Sufficiently constraint, four bursts of ethylene propylene rubber insulated core twistings during transport, installation, use effectively being prevented, the degree of packing is high,
So as to ensure the service life of cable.
The inside of the arc pad 2 is provided with cushion chamber 2a, cushion chamber 2a design, can further to use during
The power such as impact further buffer, so as to also play a part of buffer protection to four strands of ethylene propylene rubber insulated cores of inside.
The ethylene propylene rubber insulated core includes conductor 4, is extruded in the ethylene propylene rubber insulated layer 3 in the outside of conductor 4.This practicality
It is new to use EP rubbers as insulating barrier, so as to improve the performance of insulation.
