Abstract
The utility model discloses a kind of shield type multicore spring electric wire, including restrictive coating and many insulation core wires being arranged in restrictive coating, the restrictive coating is cold-resistant TPU polyethers plastics, provided with tissue paper layer in restrictive coating, insulating barrier, screen layer and nylon twisted wire layer are sequentially provided with outside the wire in every insulation core wire.Insulated wire cores set screen layer, cable is enabled to eliminate the electromagnetic interference that high current is brought, external sheath layer is using cold-resistant TPU plastics, its cold resistance for having brilliance, high-tension, high-tensile strength, tough and ageing-resistant characteristic, and be kind of a ripe environment-friendly materials, nylon twisted wire layer is set outside screen layer, the flexibility and resistance to bend(ing) energy of the cable can be greatly improved.
Description
Technical field
The utility model is related to cable (line) field, in particular to a kind of shield type multicore spring electric wire.
Background technology
When some electric equipments start, the rush of current of moment reaches normal 3-8 times, therefore, and immediate current can be to it
He produces electronic pollution by electrical equipment, and severe one can influence it normally to use, for this reason, it may be necessary to effectively be shielded to connecting line, to completely cut off
Or connecting line is reduced to externalities.Further, since the temperature difference of different regions is larger, for what is used in cold district
Many instruments, connection require of a relatively high with electric wire lamp, and most prominent performance is exactly cold-resistant, and common cable material is
Through that can not meet the use requirement of similar applications, as resisting cold, grade PVC sheath material could be used that at -30 DEG C, but product normally makes
It is relatively short with the life-span, and can not be moved completely during use, otherwise easily ftracture, this serious will hinder entering for scientific research
Step.In addition, cable with the frequent mobile of cable or rotates in use, cable can be distorted change after using the several months
Shape, even fracture cored wire, and these can all shorten cable life, or even triggers accident.
Utility model content
In order to overcome above the deficiencies in the prior art, task of the present utility model be to provide it is a kind of have it is good cold-resistant
Property, take into account shielding interference, and the shield type multicore spring electric wire that can flexibly bend.
The utility model task is achieved through the following technical solutions：
A kind of shield type multicore spring electric wire, including restrictive coating and many insulation core wires being arranged in restrictive coating, it is described
Restrictive coating is that tissue paper layer is provided with cold-resistant TPU polyethers plastics, restrictive coating, is sequentially provided with absolutely outside the wire in every insulation core wire
Edge layer, screen layer and nylon twisted wire layer.
It is preferred that, the insulating barrier of the every insulation core wire is provided with three naked copper wire harness in PVC insulating materials, insulation core wire
The wire closed.
It is preferred that, the screen layer is stranded proof copper-wire braided layer, and density is not less than 95%.
It is preferred that, the nylon twisted wire layer is to be formed by the stranded braiding of three nylon ropes.
It is preferred that, the shield type multicore spring electric wire is not more than 19mm around spring external diameter.
The beneficial effects of the utility model are：Insulated wire cores set screen layer so that cable can eliminate high current and bring
Electromagnetic interference, external sheath layer is its cold resistance for having brilliance, high-tension, high-tensile strength, tough and resistance to using cold-resistant TPU plastics
The characteristic of aging, and be that nylon twisted wire layer is set outside kind of a ripe environment-friendly materials, screen layer, the cable can be greatly improved
Flexibility and resistance to bend(ing) energy.

Fig. 1 is the cross section structure schematic diagram of shield type multicore spring electric wire of the present utility model；
Fig. 2 is the helical spring-like structures schematic diagram of shield type multicore spring electric wire of the present utility model；
Fig. 3 is the cross section structure schematic diagram of single insulated wire cores in shield type multicore spring electric wire of the present utility model；
Wherein, 1- restrictive coatings, 2- insulation core wires, 3- tissue papers layer, 4- insulating barriers, 5- screen layers, 6- nylon twisted wire layer, 7- spiral shells
Revolve spring-like electric wire.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but protection model of the present utility model
Enclose the scope for being not limited to embodiment statement.
As shown in Figure 1-2, a kind of shield type multicore spring electric wire, including restrictive coating 1 and many be arranged in restrictive coating 1
Insulation core wire 2, the restrictive coating 1 is provided with tissue paper layer 3 in cold-resistant TPU polyethers plastics, restrictive coating 1, in every insulation core wire 2
Wire outside be sequentially provided with insulating barrier 4, screen layer 5 and nylon twisted wire layer 6.Insulated wire cores 2 set screen layer 5 so that cable energy
The electromagnetic interference that high current is brought enough is eliminated, external sheath layer 1 is using cold-resistant TPU plastics, and it has the cold resistance of brilliance, height
Power, high-tensile strength, tough and ageing-resistant characteristic, and be that nylon twisted wire layer 6 is set outside kind of a ripe environment-friendly materials, screen layer,
The flexibility and resistance to bend(ing) energy of the cable can be greatly improved.
It is preferred that, the insulating barrier 4 of the every insulation core wire is provided with three bare copper wires in PVC insulating materials, insulation core wire 2
The wire that beam is closed.
It is preferred that, the screen layer 5 is stranded proof copper-wire braided layer, and density is not less than 95%.
It is preferred that, the nylon twisted wire layer 6 is to be formed by the stranded braiding of three nylon ropes.
It is preferred that, the shield type multicore spring electric wire can be fabricated to coil spring shape electric wire 7 by specific purpose tool, its around
Spring external diameter is not more than 19mm.
Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.People in the art
Member should be appreciated that utility model scope involved in the application, however it is not limited to the particular combination of above-mentioned technical characteristic
Technical scheme, while should also cover in the case where not departing from utility model design, by above-mentioned technical characteristic or its be equal
Feature be combined formed by other technical schemes.Such as features described above has with (but not limited to) disclosed herein
The technical characteristic for having similar functions carries out technical scheme formed by replacement mutually.
