Abstract
The utility model relates to a pair-twisted control cable belonging to the field of wires and cables and consisting of a plurality of pair-twisted insulating cable cores, an aluminum-plastic belt, a metal-wire braided shield and an outer sheath, wherein the pair-twisted insulating cable cores are twisted by a pair of insulating cable cores with same specification; and the pair-twisted directions of different cables are same, and the twisted-pitches are different. The insulating cable cores are combined into the cable after pair-twisted. The outside of the pair-twisted insulating cable core is wrapped with the aluminum-plastic belt and a copper-wire braided shielding network; and the outer layer is a cable sheath. The pair-twisted control cable can effectively reduce the mutual interference among signals and has higher practical value.
Description
Technical field
The utility model pair twist control cable belongs to the electric wire field.
Background technology
The general control cable for to the bar insulation core by unified stranded the forming of layering, to advance the phase mutual interference at transmission signals bigger for different core in the use.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art, and provides the mutual interference of a kind of transmission signals phase little pair twist control cable.
The purpose of this utility model reaches by following measure, the utility model pair twist control cable is made of insulated wire cores, plastic-aluminum band, metal wire knitted shielding and oversheath, insulated wire cores is by a pair of or some to stranded the forming of the identical insulated wire cores of specification, not collinear pair twist is to identical, the twisting pitch difference.Insulated wire cores is unified again stranding behind pair twist.Being surrounded by plastic-aluminum band and copper wire braid shielded net in pair twist insulated wire cores outside, is cable cover(ing) at skin.
The plastic-aluminum band that is surrounded by outside the pair twist insulated wire cores of the present utility model, with copper wire braid shielded net parcel, wrapped plastic-aluminum band, outermost layer is a cable cover(ing).
The utility model can effectively reduce phase mutual interference between the signal, has higher utility.
Description of drawings:
Accompanying drawing 1 is an example structure schematic diagram of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model pair twist control cable is made of some pair twist insulated wire cores 1, plastic-aluminum band 2, metal wire knitted shielding 3 and oversheath 4, pair twist insulated wire cores 1 is by stranded the forming of the identical insulated wire cores of a pair of specification, be surrounded by plastic-aluminum band 2 in pair twist insulated wire cores 1 outside, wrap up with copper wire braid shielded net, wrapped plastic-aluminum band 2, outermost layer are cable cover(ing)s 4.
Claims (2)
1. pair twist control cable, constitute by insulated wire cores, plastic-aluminum band, metal wire knitted shielding and oversheath, it is characterized in that the edge core by a pair of or some, be surrounded by plastic-aluminum band and copper wire braid shielded net in pair twist insulated wire cores outside to stranded the forming of the identical insulated wire cores of specification.
2. pair twist control cable according to claim 1 is characterized in that being surrounded by the plastic-aluminum band in pair twist insulated wire cores outside, and with copper wire braid shielded net parcel, wrapped plastic-aluminum band, outermost layer is a cable cover(ing).
