Abstract
The utility model discloses a three-core waterproof gas guide shielded cable. The three-core waterproof gas guide shielded cable comprises three conductive metal wires with insulation protection layers, as well as a shielding layer and an outer sheath, which are enclosed outside the conductive metal wires, and the three-core waterproof gas guide shielded cable at least comprises one of the following structural forms: a) in addition to the three conductive metal wires with the insulation protection layers, a group of gas guide tubes are also wrapped in the shielding layer; b) a radial anti-water seepage layer is increased between the shielding layer and the outer sheath; and c) a water blocking tape sleeve layer for preventing axial water seepage is arranged in the shielding layer. The three-core waterproof gas guide shielded cable can not only realize conduction and shield the influence of ambient voltage, but also conduct gas at the two ends of the cable, bear a certain vertical stress, bear a certain high temperature, prevent acid and alkali corrosion and absorb axially seeped liquid in a conducting wire.
Description
Technical field
The utility model relate to a kind of can waterproof, the shielded type cable of air guide.
Background technology
At present, existing three-core shielding cable is comprised of conductive metal wire, wire insulation protective layer, screen, outer jointing jacket.Wire two ends are connected with related device respectively, play electric action.But general wire can not play air guide, anti-acid and alkali corrosion, can not absorb the liquid that axially infiltrates in wire and bear the effect that pulls stress.
The utility model content
The purpose of this utility model is to provide three good core water-proof gas-guide shielded type cables of a kind of result of use, and it can overcome the deficiencies in the prior art.
For achieving the above object, the utility model is taked following design:
A kind of three core water-proof gas-guide shielded type cables comprise three with the conductive metal wire of insulating protective layer and go along with sb. to guard him screen and oversheath outside them; It possesses a kind of in following version at least:
A) except three with the conductive metal wire of insulating protective layer also one group of wireway together be wrapped in the middle of screen;
B) increase by a water impervious layer radially between screen and oversheath;
C) the axially infiltration waterstop jacket layer of setting up defences within described screen.
The radially water impervious layer of described three core water-proof gas-guide shielded type cables is jacket layers of being made by polytetrafluoroethylmaterial material; Described anti-axially infiltration waterstop jacket layer is the jacket layer of being made by nonwoven fabrics.
One group of wireway of described three core water-proof gas-guide shielded type cables is distributed in three with the center of the conductive metal wire of insulating protective layer.
In described three core water-proof gas-guide shielded type cables; also have that three groups of anti-interstitial wires that axially pull are common to be wrapped in the middle of screen with the conductive metal wire of insulating protective layer and one group of wireway with three, these three interstitial wires separate three conductive metal wires with insulating protective layer respectively.
Three groups of described three core water-proof gas-guide shielded type cables anti-interstitial wires that axially pull and three mutual cross arrangements of the conductive metal wire with insulating protective layer are in the outside of wireway and form a closed circular.
The anti-interstitial wire that axially pulls of described three core water-proof gas-guide shielded type cables is the polyvinyl chloride pipeline with hollow hole, and this hollow hole is built-in with the anti-nylon rope core that axially pulls.
The utility model is particularly useful for measuring liquid level to be used with the transducer connection of downforce, the liquid level degree of depth and other various liquid parameters.
The utility model has the advantages that: this three cores water-proof gas-guide shielded type cable not only can conduct electricity and shield the environment voltage influence, and can the conducting cable gas at two ends, bear certain vertical stress, bear certain high temperature, anti-acid and alkali corrosion and can absorb the liquid that axially infiltrates in wire.
Description of drawings
Fig. 1 is the utility model three core water-proof gas-guide shielded type cable one preferred embodiment structural representations.
Below in conjunction with drawings and the specific embodiments, the utility model is described further.
Embodiment
As shown in Figure 1, a preferred embodiment of the utility model three core water-proof gas-guide shielded type cables mainly is the aforesaid anti-interstitial wire that axially pulls by one group of polyvinyl chloride wireway 1, three tin-coated copper wires 2 and the outer polyvinyl chloride wire insulating sheath 3 of wrapping up in, three groups of polyvinyl chloride filling core 4(), the oversheath 8 of anti-axially infiltration waterstop 5, tinned copper wire braid shielded net 6, the anti-radially permeable layer 7 of polyethylene and polyvinyl chloride and acrylonitrile-butadiene rubber compound constitutes.
Described one group (has one in one group of this embodiment; also one of many compositions group) polyvinyl chloride wireway 1 is distributed in three with the center (that is being the cross section of the utility model three core water-proof gas-guide shielded type cables) of conducting metal tin-coated copper wire 2 circles that enclose of insulating protective layer (being polyvinyl chloride wire insulating sheath 3 in the present embodiment); can the conducting cable gas at two ends, equilibrium air pressure.
In the present embodiment; the protection jacket layer (can be heat-resisting 105 ℃) that described oversheath 8 can be comprised of polyvinyl chloride and acrylonitrile-butadiene rubber compound; can add the radially water impervious layer 7 that one deck is made by polytetrafluoroethylmaterial material between oversheath 8 and tinned copper wire braid shielded net 6, the anti-radially permeable layer of polyethylene can prevent that liquid from radially infiltrating the inside of cable.The internal layer of tinned copper wire braid shielded net 6 adds an anti-axially infiltration waterstop 5 again, and this anti-axially infiltration waterstop 5 is to be made by the nonwoven fabrics material, can prevent from seeing through the liquid of oversheath 8 and anti-radially permeable layer 7 in inner axial diffusion.Can protect wire like this, effectively prevent acid and alkali corrosion, and these material layers all have certain thickness, can bear the axial pulling of 15Kg.
Described three groups of polyvinyl chloride filling cores 4 can be with three mutual cross arrangements of the conductive metal wire with insulating protective layer in the outside of wireway 1 and form a closed circular; can be more than one in every group; preferably with an isometrical polyvinyl chloride filling core of the conductive metal wire external diameter of insulating protective layer; this polyvinyl chloride filling core 4 can be with centre bore; centre bore is built-in with nylon rope 41, more to strengthen anti-axial pulling.
The various embodiments described above can not break away from some variations in addition under scope of the present utility model, thus above explanation comprise should be considered as exemplary, but not the protection range of applying for a patent in order to limit the utility model.
