Abstract
The utility model relates to an improvement technology of communication cables, in particular to a mobile control cable capable of bearing high and low temperature and applicable for field. The mobile control cable comprises a wire group formed by four insulated wires, and is characterized in that the outer side of the wire group is clad by a bare copper wire braiding layer, and the outer side of the bare copper wire braiding layer is clad by an irradiation cross-linking type rubber elastomer sheath. The mobile control cable capable of bearing high and low temperature and applicable for field resolves the problems of bad high and low temperature performance, low tensile strength and short field service life, and is suitable to field communication under a severe environment.
Description
Technical field
The utility model relates to telecommunication cable improvement technology, especially a kind ofly is applicable to that open-air high-low temperature resistant moves control cable.
Background technology
Open-airly in the market uses that to move control cable mainly be to be the inside conductor group with four insulated cores, outside employing polyvinyl chloride elastomer or common vulcanized rubber are as cable cover(ing).The serviceability temperature scope-20 of polyvinyl chloride elastic body jacket ℃～105 ℃, when ambient temperature was lower than-25 ℃, it is big that cable hardness becomes rapidly, bending property will occur and sharply descend, and causes the cable cover(ing) cracking.The serviceability temperature scope-55 of common vulcanized rubber sheath ℃～70 ℃, when ambient temperature reached 105 ℃, material can quick aging, and the sheath performance sharply descends, and the tensile strength of this cable is also lower, and open-air useful life is short.
Summary of the invention
The purpose of the utility model will solve exactly that common field is poor with portable control cable high and low temperature resistance, and tensile strength is low, and short problem provided a kind of and was applicable to that open-air high-low temperature resistant moves control cable open-air useful life.
The concrete scheme of the utility model is: be applicable to that open-air high-low temperature resistant moves control cable; Include the lead group that four insulated cores are formed; It is characterized in that: be covered with the bare copper wire braid in lead group external packets, and be covered with irradiation crosslinking type rubber elastomer sheath in bare copper wire braid external packets.
Insulated wire cores described in the utility model is by the stranded inner wire that forms of the tinned copper wire of 19 diameter 0.15mm, is coated with the perfluoroethylene-propylene insulating barrier.
The braid of bare copper wire described in the utility model density is not less than 80%, and the per share radical/filament diameter of its number of spindles * is 24*6/0.2mm.
The rubber elastomer of irradiation crosslinking type described in the utility model jacket thickness is 1.5mm.
The utility model has adopted the good irradiation crosslinking type rubber elastomer sheath of high-low temperature resistant softness; The environment for use temperature range reaches-55 ℃-125 ℃; Can satisfy the instructions for use under the particular surroundings; And adopted the naked copper wire sheathing, tensile strength is improved a lot, open-air long service life.
Description of drawings
Fig. 1 is the view profile of the utility model.
Among the figure: 1-insulated wire cores, 2-naked copper wire sheathing, 3-irradiation crosslinking type caoutchouc elasticity sheath.
Embodiment
Referring to Fig. 1; The utility model includes the lead group that four insulated cores 1 are formed; Particularly: be covered with bare copper wire braid 2 (said bare copper wire braid 2 density are not less than 80%, are specially 85%, the per share radical of its number of spindles */filament diameter 24*6/0.2mm) in lead group external packets; And being covered with irradiation crosslinking type rubber elastomer sheath 3 in bare copper wire braid 2 external packets, said irradiation crosslinking type rubber elastomer sheath 3 thickness are 1.5mm.
Insulated wire cores described in the present embodiment 1 is by the stranded inner wire that forms of the tinned copper wire of 19 diameter 0.15mm, is coated with the perfluoroethylene-propylene insulating barrier.
