Abstract

The utility model discloses a flat cable with a butyronityile polyvinyl chloride jacket. The flat cable comprises a plurality of parallelly-arranged wire cores. Each wire core is formed by twisting a plurality of tinned copper wires into a bundle and winding a non-woven fabric taped covering outside. A butyronityile polyvinyl chloride insulation layer is arranged inside the non-woven fabric taped covering and coats the plurality of tinned copper wires. The non-woven fabric taped coverings of the plurality of the wire cores are respectively coated with copper wire woven shielding layers. Two of the plurality of wire cores form a group and the copper wire woven shielding layers are coated with a steel wire armor which is formed by twisting steel wires into bundles and weaving the wire bundles. The plurality of steel wire armors are coated with a flat structured butyronityile polyvinyl chloride outer jacket layer. A high-temperature resistant cellosilk inside liner is filled between the butyronityile polyvinyl chloride outer jacket layer and the steel wire armors. The flat cable provided by the utility model has an ingenious structure. The butyronityile polyvinyl chloride protective layer and the steel wire armors are respectively arranged inside the wire cores, thus enhancing mechanical property. In addition, the butyronityile polyvinyl chloride compound material has good high-and-low temperature resistance, and the service time is prolonged.

Description

The flat cable of butyronitrile pvc sheath

Technical field:

The utility model relates to cable, mainly is a kind of flat cable of butyronitrile pvc sheath.

Background technology:

In some adverse circumstances; need to use the cable with protective nature between the mobile appliance equipment in places such as picture generating, metallurgy, chemical industry, harbour; want high-low temperature resistant; high pressure resistant, also to have the characteristic of certain anti-mechanical strength, all is the protective layer that has heatproof in the cable outer layer setting generally; the cable conductor inside does not arrange; if layer structure destroys, then whole cable needs to change again, also cost of idleness.

The utility model content:

Technical problem to be solved in the utility model provides a kind of flat cable of butyronitrile pvc sheath; its structure is ingenious; core inside is respectively equipped with butyronitrile polyvinyl chloride protective layer and wire armoring layer; strengthened mechanical performance; and the high and low temperature resistance of butyronitrile polyvinyl chloride composite material is good, and service time is long.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of flat cable of butyronitrile pvc sheath, include the core of a plurality of parallel arrangements, described core is around with the nonwoven fabrics lapping layer after by the many stranded bunchys of tinned copper wire and forms, be provided with one deck butyronitrile polyvinyl chloride insulation layer in the described nonwoven fabrics lapping layer and be coated on outside the many tinned copper wires, the nonwoven fabrics lapping layer of described a plurality of cores is coated with copper wire establishment screen outward respectively; Described a plurality of core is formed one group of wire armoring layer that is coated with the stranded bunchy braiding of steel wire outside copper wire establishment screen jointly in twos, and described wire armoring layer is flat structure; Outside the wire armoring layer of many groups, be coated with the butyronitrile polyvinyl chloride external sheath layer of flat structure jointly.

In the described butyronitrile polyvinyl chloride external sheath layer and be filled with the inner covering of high-temperature fibre silk between the wire armoring layer.

This is flat structure with cable design for the utility model, compact conformation, the convenient installation; In the internal core of cable, be equipped with the protective layer of butyronitrile pvc material with external structure, strengthened the characteristic of cable.

The utility model is applicable to that ac rated voltage 450/750V and following control, monitoring loop, various movable electrical appliances, wireless device and illuminating lamp holder line usefulness and protection circuit etc. require the occasion of operation.

The utility model has the advantages that:

The utility model structure is ingenious, and core inside is respectively equipped with butyronitrile polyvinyl chloride protective layer and wire armoring layer, has strengthened mechanical performance, and the high and low temperature resistance of butyronitrile polyvinyl chloride composite material is good, service time.

Description of drawings:

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

Embodiment:

Referring to Fig. 1, a kind of flat cable of butyronitrile pvc sheath, include the core of a plurality of parallel arrangements, described core is around with nonwoven fabrics lapping layer 2 after by many tinned copper wires 1 stranded bunchy and forms, be provided with one deck butyronitrile polyvinyl chloride insulation layer 3 in the described nonwoven fabrics lapping layer 2 and be coated on outside the many tinned copper wires 1, the nonwoven fabrics lapping layer 2 outer copper wire establishment screens 4 that are coated with respectively of described a plurality of cores; Described a plurality of core is formed one group of wire armoring layer 5 that is coated with the stranded bunchy braiding of steel wire outside copper wire establishment screen 4 jointly in twos, and described wire armoring layer 5 is flat structure; Outside the wire armoring layer 5 of many groups, be coated with the butyronitrile polyvinyl chloride external sheath layer 6 of flat structure jointly.

In the described butyronitrile polyvinyl chloride external sheath layer 6 and be filled with the inner covering 7 of high-temperature fibre silk between the wire armoring layer 5.
