Abstract

The utility model discloses a cable for an AC/DC configuration circuit, which comprises three alloy conductors. A flat plastic tape, an inner cotton yarn braid layer and a polytetrafluoroethylene insulating layer spirally wound each of the three alloy conductors for forming insulated wire cores. The inner cotton yarn braid layer is made of cotton yarn and is waved to a net-shaped member. The braiding density is not less than 90%. The polytetrafluoroethylene insulating layer is integrated with the inner cotton yarn braid layer through extrusion forming. The insulated wire cores form a cable core in a delta-shape around a hollow pipe which is formed through performing extrusion on polyurethane elastomer, thereby forming a cable core. A foam plastic layer, an outer cotton yarn braid layer and an outer sleeve layer are successively coated outside the cable core. The cable for the AC/DC configuration circuit has an advantage of novel design. The design with the inner cotton yarn braid layer and the cotton yarn braid layer, the plastic tape and the foam plastic layer greatly improves structure compactness of the cable. After cabling, the cable has a smaller outer diameter and smaller total weight, thereby facilitating mounting and laying. Simultaneously the cable has excellent warp resistance and high flexibility.

Description

A kind of AC/DC configuration circuit cable

Technical field:

The utility model relates to communication cable, relates in particular to a kind of AC/DC configuration circuit cable.

Background technology:

In communication system, communication cable is mainly used in the AC/DC configuration circuit, cable duct, and the wire clamp in the communication central office and irrigation canals and ditches, power distribution station, in mobile phone launching tower and other mobile devices.

The cable of AC/DC configuration circuit occasion use at present, structural compactness is poor, and the unreasonable outside diameter of cable that causes of global design is larger, occupies more position in limited space, and mounting and installation is inconvenience quite; In addition, also the warp resistance performance of demand cable is relative with flexibility poor, and long-term stability in use is relatively poor.

The utility model content:

In order to make up the prior art problem, the purpose of this utility model is to provide a kind of AC/DC configuration circuit cable, and structural compactness is good, has less entire outer diameter less, is convenient to mounting and installation; Cable also has good warp resistance performance and flexibility.

The technical solution of the utility model is as follows:

AC/DC configuration circuit cable, comprise three alloy conductors, it is characterized in that: described three alloy conductors outer respectively successively spiral winding the plastic tape of flat is arranged, interior cotton braid, the teflon insulation layer forms insulated wire cores, interior cotton braid adopts cotton braid to reticulate, count is not less than 90%, the teflon insulation layer is integral through extrusion moulding and interior cotton braid, insulated wire cores forms cable core in a triangle centered by the hollow pipe of polyurethane elastomer extrusion moulding, cable core is coated with the foamed plastic layer outward successively, outer cotton braid, external sheath layer.

Described AC/DC configuration circuit cable is characterized in that: the plastic tape spiral winding spacing of described flat is not more than 0.8mm.

The utility model has the advantages that:

The utility model structural design is novel, the design of inside and outside double-deck cotton braid, plastic tape, foamed plastic layer, promoted greatly the structural compactness of cable, has less external diameter after stranding, lighter total weight, be convenient to mounting and installation, cable also has good warp resistance performance and flexibility simultaneously.

Description of drawings:

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

Embodiment:

Referring to Fig. 1:

AC/DC configuration circuit cable, comprise three alloy conductors 1, three alloy conductors 1 outer respectively successively spiral winding the plastic tape 2 of flat is arranged, interior cotton braid 3, teflon insulation layer 4 forms insulated wire cores, interior cotton braid 3 adopts cotton braid to reticulate, count is not less than 90%, teflon insulation layer 4 is integral through extrusion moulding and interior cotton braid 3, insulated wire cores forms cable core in a triangle centered by the hollow pipe 5 of polyurethane elastomer extrusion moulding, cable core is coated with foamed plastic layer 6 outward successively, outer cotton braid 7, external sheath layer 8.

The plastic tape 2 spiral winding spacings of flat are not more than 0.8mm.
