Abstract
A double-layer shielding spring cable belongs to the cable technology. The utility includes a cross-linking polyethylene insulation layer, a shielding layer, a filling layer, an outer rubber protective layer, wherein, a shielding layer is arranged between the filling layer and the rubber protective outer layer, the sequence in turn from inside to outside is the cross-linking polyethylene insulation layer, the shielding layer, the filling layer, the shielding layer, the outer protective rubber layer; to bend the cables into a spring shape. The structure of the utility is reasonable and simple, easy manufacture, incorporated with a double-layer copper-aluminum shielding layer, of which the shielding performance can not only reach a desired result, but can also save a lot of copper. The structure can not only be applied to the cables of electrical equipment but also be widely used for cable shielding in electric power and communications widely, thereby having good market value. The spring type bending can use the utility model flexibly.
Description
(1) technical field
The utility model relates to a kind of cable, and especially a kind of double layer screen spring cable belongs to the cable technology field.
(2) background technology
Cable is widely used in the electric connection of all kinds of electronic devices such as electric tool, instrument and meter, household electrical appliance and automation equipment as the delivery means of a kind of transferring electric power signal or data-signal.In addition, because electric power or signal, the especially high-frequency signal of cable transmission disturbed by extraneous electromagnetic signal very easily, thereby cable often need adopt the shielding construction design to eliminate or to reduce the influence of external electromagnetic field, also can prevent the leakage of transmission signals simultaneously.
(3) utility model content
[problem that will solve]
The purpose of this utility model is to provide a kind of shielded type cable at the deficiency that above-mentioned prior art exists, and this shielded type cable adopts double shield layer structural design improving the effect of anti-electromagnetic interference, and then guarantees the reliability of signal transmission.The bending of spring shape can be used the utility model product flexibly.
[technical scheme]
Be achieved through the following technical solutions above-mentioned purpose:
A kind of double layer screen spring cable, comprise the crosslinked polyetylene insulated layer that coats on the lead, screen, packed layer, outer layer rubber protective layer, it is characterized in that: between packed layer and outer layer rubber protective layer, also have one deck screen, the order of coated wire is successively from inside to outside: crosslinked polyetylene insulated layer, screen, packed layer, screen, the outer layer rubber protective layer; Wherein, the lead that above-mentioned multilayer is coated bends to and is the spring shape, and advantage is that the bending of spring shape can be used the utility model product flexibly.Employing extrudes technology and evenly coat crosslinked polyetylene insulated layer, thickness 0.6-0.9 millimeter on conductor.Packed layer adopts material conventional in the prior art, is one or more in alkali-free mineral wool rope, fire resistant polyethylene, alkali-free glass wool, fire-resistant mica, polypropylene mesh fiber and the strand, and preferred wherein three kinds mix with arbitrary proportion and use.
Above-mentioned two-layer screen all is the net that copper wire and aluminium wire are woven into.The part by weight of copper wire and aluminium wire is: 1: 0.5-5.
Above-mentioned spring diameter is 0.5-3 centimetre.
[beneficial effect]
Advantage of the present utility model is as follows: the utility model is rational in infrastructure simple, manufactures easily, adopts double-deck copper aluminium shielding layer, and not only shielding properties reaches ideal effect, and can save a large amount of copper materials.This structure not only can be applied to the electrical equipment cable, also can be widely used in the shielding of cables such as electric power, communication, and good market using value is arranged.The bending of spring shape can be used the utility model product flexibly.
(4) description of drawings
Fig. 1 is the utility model cable stereogram of spring shape;
Fig. 2 is the utility model cable cross-section schematic diagram.
(5) embodiment
Describe in detail below in conjunction with attached Fig. 1 and 2:
Among Fig. 1, the utility model cable stereogram of spring shape, cross section 7.
Fig. 2 is the cable cross-section schematic diagram, i.e. cross section 7 among Fig. 1.
