Abstract

The utility model relates to an industrial control cable with shielding for dragging, which comprises conductors, an aramid yarn filling core, a tinned copper wire braid shielding layer and a PVC (polyvinyl chloride) jacket, wherein each conductor is formed by stranding a zinc-coated wire and a plurality of tinned copper wires, a layer of PVC insulating layer is extruded and wrapped outside the conductor to form an insulated conductor, the aramid yarn filling core is arranged among the four insulated conductors for stranding, the tinned copper wire braid shielding layer is braided outside the insulated conductors, and the PVC jacket is extruded and wrapped outside the shielding layer. The industrial control cable with shielding for dragging provided by the utility model has the beneficial effects that: tensile components are reasonably distributed, the problem of non-uniform stress is solved by the zinc-coated wires and stranded aramid yarns, the tinned copper wire braid is added, and the problems of shielding and anti-interference are solved.

Description

The band shielding pulls uses industrial control cable

Technical field

The utility model relates to a kind of cable, and particularly a kind of being applicable to is with shielding to pull the Industry Control cable.

Background technology

In modern industry, the effect that cable plays is transmitted except signal, outside electric power is supplied with and is controlled, even can play drag interaction, can effectively save the space like this, reduce the pulling force components and parts, but the composite performance index to cable is more and more higher like this, at the cable that pulls in the past, often simple weaves the aramid fiber silk in the stranded back of heart yearn, will cause cable discontinuity to occur like this in the load-bearing process, the fracture of aramid fiber silk occurs, finally cause cable to be connected fracture with equipment, influence is normally used.

Summary of the invention

In view of the deficiency and the market demand that prior art exists, the utility model provides a kind of band shielding to pull and has used industrial control cable.Its structure Design can reach the market instructions for use fully.

The utility model for achieving the above object, the technical scheme that is adopted is: a kind of band shielding pulls uses industrial control cable, it is characterized in that: comprise the conductor that zinc-coated wire and several tinned wird are twisted into, outside conductor, extrude one deck PVC insulating barrier and constitute insulated conductor, also comprise aramid fiber silk filled core, the tinned wird braid, the PVC sheath, it is stranded in the middle of four described insulated conductors an aramid fiber silk filled core to be set, braiding tinned wird screen extrudes one deck PVC sheath outside screen outside it.

The beneficial effects of the utility model are: reasonably distributed the tension components and parts, galvanized steel wire and assembly strand aramid fiber silk has solved the problem of discontinuity; Increase the tinned wird braiding and solved the shielding anti-interference problem.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

As shown in Figure 1, the band shielding pulls uses industrial control cable, comprise single core zinc-coated wire 1-1, tinned wird 1-2, PVC insulating barrier 1-3, aramid fiber silk filled core 2, tinned wird braid 3, PVC sheath 4, described zinc-coated wire 1-1 and several tinned wird 1-2 are twisted into conductor, outside conductor, extrude one deck PVC insulating barrier 1-3 and constitute insulated conductor 1, it is stranded in the middle of the four eradication edge leads 1 an aramid fiber silk filled core 2 to be set, braiding tinned wird screen 3 extrudes one deck PVC sheath 4 outside screen 3 outside it.

The utility model can obtain by following technical process manufacturing: single core galvanized steel wire 1-1 as center conductor and tinned wird 1-2 as inner wire, (the utility model is a six roots of sensation tinned wird) is twisted into conductor by the synnema machine, outside conductor, extrude one deck PVC(polyvinyl chloride by plastic extruding machine) insulating barrier, above structure constitutes insulated conductor 1, thoroughly do away with the edge lead 1 a middle assembly strand aramid fiber silk filled core 2 that is longitudinally set with four, undertaken stranded by the synnema machine, can solve the problem of filling like this, make the cable rounding, lifting aramid fiber tension efficient that can be maximum again, outside it, weave tinned wird screen 3 by braiding machine, improve the interference free performance of cable, outside screen 3, extrude one deck PVC sheath 4 and play protective action for this electricity core by the machine of extruding.

Claims

1. a band shielding pulls and uses industrial control cable, it is characterized in that: comprise the conductor that zinc-coated wire (1-1) and several tinned wirds (1-2) are twisted into, outside conductor, extrude one deck PVC insulating barrier (1-3) and constitute insulated conductor (1), also comprise aramid fiber silk filled core (2), tinned wird braid (3), PVC sheath (4), it is stranded in the middle of four described insulated conductors (1) an aramid fiber silk filled core (2) to be set, braiding tinned wird screen (3) extrudes one deck PVC sheath (4) outside screen (3) outside it.
