Abstract

A tensible flexible control cable is characterized in that a conductor adopts a naked copper wire or a tin plating flexible copper wire, an insulting core formed by ethylen-propylene rubber insulating layers is extruded on the conductor, a plurality of insulating corns are twisted to be a cable, thereby forming a cable core, an extruding TPV elastic body inner lining layer, a reinforced shielding layer formed by commonly kneading aramid yarn and copper wires and an extruding TPV elastic body outer sheath layer are arranged outside the cable core in turn. The tensible flexible control cable is used as a tensible flexible control cable, has the advantages of electromagnetic disturbance resistance, flexibility, convenient laying and the like, simultaneously has higher abrasion resistance, winding resistance and pulling resistance, and is suitable for being used as connecting lines for electric energy and signal control of mobile devices.

Description

A kind of tension soft type control cable

Technical field

The utility model relates to a kind of electrical equipment control cable, relates in particular to a kind of tension soft type control cable, belongs to technical field of electric wires and cables.

Background technology

Electric wire is as electrical equipment corollary equipment connecting line, and its key property is exactly the environmental quality that will adapt to the electrical equipment operation.Along with The development in society and economy, fields such as mining industry, traffic construction, building industry, exploration operation, operating environment is abominable, and electrical equipment all is mobile operating basically.Connection control cable between its electrical equipment need have stronger tension, wear-resisting,, anti-ly circumnutate, characteristic such as softness and long-life.On the other hand, the same with other equipment, preferably have characteristics such as in light weight, that structure is little.

This class cable employing rubber do insulation of existing market and sheath are in the majority, and it has flexibility, but shortcoming is complexity of manufacturing process, causes cost higher.If adopt the plastics class to make insulating barrier and restrictive coating fully, performance is difficult to reach requirement.Therefore, adopt new material and newest structure designing technique, manufacturing property excellence, cheap or easily manufactured tension soft type control cable are particularly necessary.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, provide and have certain anti-electromagnetic interference, softness, lay advantages such as convenient, have stronger resistance to wear simultaneously, anti-ly circumnutate, tension drags, and satisfies mobile class equipment electric energy, signal controlling with tension soft type control cable.

The utility model adopts following technical scheme:

The design feature of the utility model tension soft type control cable is that conductor adopts bare copper wire or tin annealed copper wire, extrudes the ethylene-propylene rubber insulating barrier and constitute insulated wire cores on conductor; By the stranded stranding of a plurality of insulated wire cores, constitute cable conductor; Outside described cable core, set gradually the reinforced screen that extrudes TPV elastomer inner covering, constitutes by aramid yarn and copper wire co-braided and extrude TPV elastomer external sheath layer.

The design feature of the utility model tension soft type control cable also is:

Described conductor adopts performance index to meet the 5th kind or the 6th kind of flexible conductor material of GB/T3956-2008.

Describedly be used to weave that the aramid yarn that constitutes reinforced screen is identical with the copper wire number of spindles, direction is opposite;

Described inner covering and outer jacket are the dynamic vulcanization elastomer blends TPV of base material for the thermoplasticity Ethylene Propylene Terpolymer.

Described inner covering and outer jacket form for crowded tubular type extrudes.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the ethylene-propylene rubber compound is adopted in the utility model insulation, and it has good electrical properties, heat resistance and mechanical performance, has higher elasticity and softness simultaneously;

2, the utility model inner covering and external sheath layer adopt environmental protection type thermoplastic elastomer TPV, and this material has higher mechanical strength, desirable softness and the splendid processing technology of extruding.Elasticity and softness with rubber also have the high-intensity performance of plastics;

3, the utility model conductor adopts the 5th kind or the 6th kind of flexible conductor material, has guaranteed the good bending property and the flexibility of cable;

4, the utility model screen adopted high strength and modulus the aramid fiber silk/the copper wire number of spindles is identical, direction weaves on the contrary, on the one hand the aramid fiber silk has certain tension effect, bears external force and pulls mechanical stress on the cable, plays the effect of protection cable; Copper wire has capability of electromagnetic shielding; This on the other hand structural design designs than layering, and compact conformation reduces construction of cable size;

5, the utility model inner covering and external sheath layer adopt to squeeze tube process, guarantee that inner covering and sheath and cable core, screen combine closely, and the tension of raising cable is dragged performance, reduces construction of cable size.

Description of drawings

Fig. 1 is the utility model construction of cable schematic diagram.

Number in the figure: 1 conductor, 2 insulated wire cores, 3 inner coverings, 4 reinforced screens, 5 external sheath layers.

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment

Referring to Fig. 1, in the present embodiment, conductor 1 adopts tin annealed copper wire, specifically adopts performance index to meet the flexible conductor material of the 5th kind or the 6th kind regulation of GB/T3956-2008;

Shown in Figure 1, on conductor 1, extrude the ethylene-propylene rubber insulating material and constitute insulated wire cores 2; By a plurality of insulated wire cores 2 stranded strandings, constitute cable conductor; Outside cable core, extrude the reinforced screen 4 of inner covering 3, aramid yarn/copper wire braiding formation successively; Outside screen 4, extrude external sheath layer 5.

In concrete the enforcement, inner covering 3 and external sheath layer 5 adopt the crowded tubular type of TPV elastomeric material to extrude and form the TPV-6505 moulding mixture that specifically can adopt Shanghai Kaibo Special Cable Material Factory to produce.
