Description

A kind of novel polyvinyl chloride insulation steel tape armouring control cable

Technical field

The utility model belongs to field of cable technology, specially a kind of novel polyvinyl chloride insulation steel-tape armouring control electricity Cable.

Background technique

Armored cable is mounted in the metal sleeve for having insulating materials by different material conductors, is processed to flexible Solid assembly.Armored cable includes armoured thermocouple, armoured thermal resistance, sheathed heater and armoring lead wire, being mainly used for Temperature measurement, signal transmission and the special heating of work, metallurgy, machine-building, power generation and scientific experimentation etc., maximum dosage is armour Fill thermocouple.Armored cable mechanical protection layer may be added on the cable of any structure, to increase the mechanical strength of cable, improve Erosion prevention is the wire and cable that designs for vulnerable to mechanical damage and extremely erodible area.Any one can be used Kind mode is laid, and the directly buried installation of Rock Region is more suitable for.Armored cable is usually fixed power cable laying, it is popular for It is exactly fixed on a place and does not move substantially, power line transmits electric energy.Cable adds the purpose of armor in addition to above, also The mechanical protections such as tensile strength, compression strength can be enhanced to prolong the service life.Armouring has certain external force resistance performance, may be used also It is baited with watching out for mouse, is unlikely to cause power transmission problem through armouring, the bending radius of armouring is big, and armor can connect Cable is protected on ground.

However existing polyvinyl chloride insulation steel tape armouring control cable due to inside stuffing filling uniformly, and it is external Steel band hardness is larger, so that control cable bend angle is smaller, it is not pliable, and and internal wiring shield effectiveness is not strong, over long distances It is serious to transmit signal decaying.

Utility model content

The purpose of this utility model is that: in order to solve polyvinyl chloride insulation steel tape armouring control cable bendability and control The problem of wired signal transmission stability processed, provides a kind of novel polyvinyl chloride insulation steel tape armouring control cable.

The technical solution adopted in the utility model is as follows:

A kind of novel polyvinyl chloride insulation steel tape armouring control cable, including the first polyvinyl chloride insulation set, steel band, second Polyvinyl chloride insulation set and core wire, the core wire are evenly arranged with seven altogether, and seven core wires are by conducting wire, third polychlorostyrene Ethylene insulation sleeve and aluminium foil wired tube composition, the outer cover of the conducting wire are equipped with third polyvinyl chloride insulation set, and third polychlorostyrene The outer cover of ethylene insulation sleeve is equipped with aluminium foil wired tube, and the outside of seven core wires is equidistantly socketed with core wire fixing sleeve, described The inside of core wire fixing sleeve corresponds to core wire position and offers core wire perforation, and the outside of the core wire fixing sleeve is socketed with the The external helicoid of two polyvinyl chloride insulation sleeves, the second polyvinyl chloride insulation set is wound with steel band, the outer cover of the steel band It is connected to the first polyvinyl chloride insulation set.

Wherein, the spacing between the two neighboring core wire fixing sleeve is identical as the thickness of core wire fixing sleeve.

Wherein, the inner inclusion of the core wire fixing sleeve has wire.

Wherein, there are six being angularly arranged outside seven core wires, center is provided with one, and adjacent two Spacing between core wire is identical.

Wherein, the second polyvinyl chloride insulation set is mutually bonded with core wire fixing sleeve.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:

1, it in the utility model, is equidistantly socketed in the outside of polyvinyl chloride insulation steel tape armouring control cable internal core Core wire fixing sleeve, and the gap between core wire fixing sleeve is identical as the thickness of core wire fixing sleeve, so that polyvinyl chloride insulation Steel tape armouring control cable can be bent in non-core wire fixing sleeve position, so that polyvinyl chloride insulation steel-tape armouring control Cable weight reduction processed, and facilitate and bent.

2, in the utility model, the outer cover of polyvinyl chloride insulation steel tape armouring control cable internal core is compiled equipped with aluminium foil Set is knitted, then in the inner inclusion wire of core wire fixing sleeve, internal core can reduce by aluminium foil wired tube and wire Between interference, while steel band can be avoided external signal and internally be interfered, so that core wire is not easy to interfere, and transmits signal It is more stable.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.

Referring to Fig.1-4, a kind of novel polyvinyl chloride insulation steel tape armouring control cable, including the first polyvinyl chloride insulation set 1, steel band 2, the second polyvinyl chloride insulation set 3 and core wire 4, core wire 4 are evenly arranged with seven altogether, and seven core wires 4 are by conducting wire 41, third polyvinyl chloride insulation set 42 and aluminium foil wired tube 43 form, and the outer cover of conducting wire 41 is equipped with third polyvinyl chloride insulation Set 42, and the outer cover of third polyvinyl chloride insulation set 42 is equipped with aluminium foil wired tube 43, the outside of seven core wires 4 is equidistantly socketed with Core wire fixing sleeve 5, the inside of core wire fixing sleeve 5 correspond to 4 position of core wire and offer core wire perforation 51, core wire fixing sleeve 5 Outside be socketed with the second polyvinyl chloride insulation set 3, the second polyvinyl chloride insulation set 3 external helicoid be wound with steel band 2, steel band 2 outside is socketed with the first polyvinyl chloride insulation set 1.

Spacing between two neighboring core wire fixing sleeve 5 is identical as the thickness of core wire fixing sleeve 5, core wire fixing sleeve 5 it is interior Portion is mingled with wire 52, and outside seven core wires 4 angularly there are six settings, center is provided with one, and adjacent two Spacing between a core wire 4 is identical, and the second polyvinyl chloride insulation set 3 is mutually bonded with core wire fixing sleeve 5.

Core wire fixing sleeve 5 is material contracting with heat, and wherein the internal diameter of the core wire perforation 51 inside core wire fixing sleeve 5 is greater than core wire 4 Outer diameter so that it is convenient to passed through to core wire 4, then by heating so that core wire fixing sleeve 5 is shunk, realize the fixation to core wire 4.
