Abstract
The utility model discloses a computer and instrument cable composed of a bearing part and a transmission part, which are arranged in parallel and are tightly connected together through outer sheathes simultaneously and respectively extruded at the outmost layers of the two parts. The bearing part includes a stainless steel wire stranded wire core coated by an outer sheath. The transmission part includes a shielding layer, a wrapping layer and a cable core, wherein the shielding layer and the wrapping layer are sequentially arranged in an outer sheath from outside to inside, the cable core is formed by twisting a plurality of insulated wire cores, a filling layer is arranged in gaps of the cable core, and each of the insulated wire cores includes a copper conductor and an insulating layer extruded outside the copper conductor. The computer and instrument cable is suitable to be used under conditions such as long-distance parallel laying, gravity load, signal transmission, electromagnetic interference, corrosion environments and the like and can fully satisfy the using requirements of a computer and instrument cable widely used nowadays.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of computer and instrument cable.
Background technology
The computer of Xiao Shouing and instrument cable mainly contain chemical corrosivity computers such as fire-retardant computer and instrument cable, fire-resistant computer and instrument cable, high temperature resistant computer and instrument cable, low temperature resistant computer and instrument cable, acid and alkali-resistance, profit and instrument cable etc. in the market, these computers and instrument cable major defect are the security performance dullnesses, and can not adapt to has two and above security performance needs; Yet a lot of occasions in industrial and mining enterprises such as electric power, oil, chemical industry, iron and steel all are to have high temperature, strong acid-base, profit and combustibility simultaneously or there are adverse circumstances in corrosive gas.If long-term general computer and instrument cable or single computer and the instrument cable of performance that uses of the Distributed Control System under such rugged environment or computer control system, its security performance will be difficult to guarantee.Active computer and instrument cable are run into bearing load such as suspension, electromagnetic interference, transmission signal ambiguity through regular meeting when day-to-day operation, cause factor such as rotten hardening to influence normal use because of environmental change.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can bear certain load, anti-electromagnetic interference, transmission signal ambiguity, improves because use the carrying shielding plastic that causes the rotten hardening unfavorable factor of cable insulate computer and instrument cable under unsuitable environmental condition.
A kind of computer described in the utility model and instrument cable, described cable is made of bearing part arranged side by side and hop, bearing part and hop closely link together by the oversheath that outermost layer extrudes simultaneously, and wherein the bearing part is to be formed by the stranded core of oversheath parcel stainless steel wire; Hop then comprises: be successively set on screen in the oversheath, lapping layer from outside to inside and by the stranded cable core that forms of some eradication edge cores, also be provided with packed layer in the gap of cable core.
Further improve, described insulated wire cores is more than two or two, and it is by copper conductor and be extruded in the outer insulating barrier of copper conductor and constitute.
Further improve, described lapping layer is aluminium foil strip.
Further improve, described screen is copper wire braid shielded structure.
Further improve, described oversheath is pvc sheath again.
The beneficial effects of the utility model:
1, conductor of the present utility model adopts real core conductor or stranded conductor, and it is simple to have manufacturing process, and quality is convenient to control, the characteristics that cost is cheap relatively;
2, this practical cable shield is double-layer shielding structure technology, vertical bag one deck aluminium foil strip shielding earlier, the copper wire braid shielded carries out second layer shielding again, such structural design, from the cause of interference analysis, interference source has been blocked on the outer screen, and it is reliable and stable that the cable transmission signal will become;
3, the utility model restrictive coating igelite, physical properties such as corrosion-resistant, the acid and alkali-resistance of its material, oil resistant are greasy, softness will be not fully exerted;
4, the utility model adopts the bearing structure design, effectively increases the tensile strength of cable, can bear certain load.
Description of drawings
Fig. 1 is that hop insulated wire cores of the present utility model is two structural representation;
Fig. 2 is that hop insulated wire cores of the present utility model is the structural representation more than two.
Embodiment
As shown in Figure 1, a kind of computer described in the utility model and instrument cable, described cable is made of bearing part arranged side by side and hop, bearing part and hop closely link together by the oversheath 7 that outermost layer extrudes simultaneously, and wherein the bearing part is to be made of the stranded core 6 of stainless steel wire that oversheath 7 wraps up; Hop then comprises: be successively set on from outside to inside the employing copper wire braid shielded structure in the oversheath 7 screen 5, adopt the lapping layer 4 of aluminium foil strip and by the stranded cable core that forms of some eradication edge cores, also be provided with packed layer 3 in the gap of cable core; Described insulated wire cores is by copper conductor 1 and be extruded in the outer insulating barrier 2 of copper conductor 1 and constitute.
Fig. 2 and Fig. 1 difference are that described insulated wire cores is five.
The utility model provides thinking and the implementation method of a kind of computer and instrument cable; concrete application approach is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
