Abstract

The utility model relates to a high and low temperature resistance spiral cable applied to TPEE polyether sheath electronic connection. The spiral cable comprises a conductor which is formed by stranding a number of annealing bare copper wires or tinned copper wires with small pitches together. An insulating layer and a shielding layer are arranged outside the conductor in order. A TPEE polyether sheath layer is arranged outside the shielding layer. The spiral cable provided by the utility model has good performances of high and low temperature resistance and flexibility, has good characteristics of water resistance, oil resistance, abrasion resistance and flame retardance, and can be continuously used in outdoor for a long time.

Description

A kind of high-and low-temperature resistance TPEE polyethers sheath electronics connects uses spiral cable

Technical field

The utility model relates to a kind of high-and low-temperature resistance TPEE polyethers sheath electronics connection and uses spiral cable, belongs to electronic apparatus connection technical field of electric wires and cables.

Background technology

Extensiveization development along with national economy and industrial economy; also promoted the development of electronic apparatus with electric wire cables manufacturing industry; laying except building need be with the various versatility cable product; all kinds of a large amount of electric wire of using at engineering machinery, tester and mobile platform; now not only need high-and low-temperature resistance; be that the high temperature requirement improves constantly; low temperature requires more and more stricter; use, folding and unfolding management to electric wire are also simple and convenient, also are the development and application research of spring cable so just impelled spiral cable.

Spiral cable also is spring cable, be by one or several groups of stranded straight shape cables that form of insulated conductor state in the shape of a spiral after circumnutating, it is the interfacility link that a kind of spiral scalability that utilizes cable comes work, in order to control the electric power of movable equipment in the motion operation process, signal connects, and can be at short notice the spiral type electric wire of resilience rapidly.

At present a large amount of spiral type cables such as TPU sheath that use are because the performances such as high-and low-temperature resistance of material are not ideal, the regular because influence of cable frequency of usage, and high-and low-temperature resistance is undesirable to be caused the fracture of electric wire even scraps.

The utility model content

The utility model is at above-mentioned defective, and purpose is to provide a kind of a kind of high-and low-temperature resistance TPEE polyethers sheath electronics with good combination property to connect and uses spiral cable.

The technical solution adopted in the utility model is for this reason: comprise that conductor is established insulating barrier, screen outward successively, screen peripheral hardware TPEE polyethers restrictive coating by many fine pith bundles strand annealing bare copper wire or conductor of forming of tinned copper wire together.

Described screen comprises branch shielding and total shielding.

Described branch shielding adopts aluminium foil to add the shielding of drainage thread branch or aluminium foil adds the annealing bare copper wire or tinned copper wire divides shielding or anneal bare copper wire or tinned copper wire braid shielded.

Annealing bare copper wire or tinned copper wire braid shielded are adopted in described total shielding.

Described insulating barrier adopts high density polyethylene (HDPE) material or the PVC modified material of flaming retarding cold resistant of high-and low-temperature resistance and high temperature thermal deformation excellent performance.

The utility model has the advantages that: 1) the utility model adopts single annealing back elongation bare copper wire or tinned copper wire preferably, add the fine pith bundle and be twisted into whole conductor, will make flexibility and the bending property of cable that assurance has preferably been arranged, the bending radius during dynamically with static laying is less; Not only have flexibility and high-and low-temperature resistance environmental performance preferably, also have water-fast, oil resistant, abrasion resistant fire blocking characteristic, weak acid resistant weak base, anti-aging, antiultraviolet, the chemical property of multiple excellences such as preventing microorganism corrosion, the physical property of multiple excellence such as tear-proof and elasticity are good; 2) restrictive coating adopts the TPEE polyethers, has good high-and low-temperature resistance, hydrolysis, anti-wear performance; 3) material of insulating barrier employing has excellent high-and low-temperature resistance and high temperature thermal deformation performance; 4) screen adopts and divides shielding and total shielding, has good shielding properties; 5) the utility model cable is not halogen-containing, and every tenor lead, cadmium, mercury equal size all meet RoHS " 6P " environmental protection index, meets RoHS " 6P " the ECO performance requirement of electronic enterprises universal demand.

Description of drawings

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

1 is that conductor, 2 is that insulating barrier, 31 is that shielding always, 4 is restrictive coating for dividing shielding, 32 among the figure.

Embodiment

The utility model comprises conductor 1 and the insulating barrier 2 that is coated on outside the conductor 1, is provided with screen successively outside the described insulating barrier 2, and screen extrudes restrictive coating 4 outward; Described conductor 1 includes the multifilament lay configuration.

Described conductor 1 is to adopt annealing elongation bare copper wire or tinned copper wire preferably, carry out stranded forming according to 10-16 bundle strand pitch doubly than carrying out the opposite rule of adjacent layer, have excellent conductor flexibility and bending property, meet the requirement of cable conductor standard.

The process of described conductor 1 external application extrusion molding coated insulation layer 2, insulating barrier 2 adopts high density polyethylene (HDPE) material or the PVC modified material of flaming retarding cold resistant of high-and low-temperature resistance and high and low temperature thermal deformation behavior excellence;

Screen is divided into the mode that branch shielding 31 adds up shielding 32, divides shielding 31 to adopt aluminium foil to add drainage thread and divides shielding or aluminium foil+annealing bare copper wire or tinned copper wire to divide shielding or annealing bare copper wire or three kinds of modes of tinned copper wire braid shielded; Total shielding 32 is the modes that adopt annealing bare copper wire or tinned copper wire braid shielded.

The fashion of extrusion that the TPEE polyether elastomer material of screen 3 outer employing high-and low-temperature resistances, hydrolysis, anti-wear performance excellence is used direct heating plasticizing extrudes restrictive coating 4.
