Abstract

The utility model relates to a gas guiding tensile resistance anti-interference cable whose gas guiding tube (1) is located in the central position of the cable along the axial direction, an insulation electric conductive wire core (2) and an insulation steel wire strengthen core (3) are twisted on the outer surface of the gas guiding tube (1) along the axial direction to form a circular cable core whose outer surface is encapsulated with a inner shielding layer (4), the inner shielding layer (4) is encapsulated with a outer shielding layer (5) which is encapsulated with a protection sleeve (6). The utility model can not only transmit multi-way electrical signal but also transmit the pressure displacement information through the gas guiding tube of the cable center, at the same time, a plurality of insulated reinforced steel wires winding around the gas guiding tube provide the cable with a strong tensile resistance force and the cable core employs a double shielding structure, which provide the cable with an excellent anti-interference ability in the environment with complex interference source such as the mine with staggered circuits.

Description

The anti-interference cable of air guide tension

Technical field

The utility model relates to the anti-interference cable of a kind of air guide tension.

Background technology

The silicon force sensitive sensor high comprehensive performance, particularly heat resistance, anti-electric shock performance and decay resistance are very outstanding, be mainly used in the down-hole water level situation of change of measuring deep wells such as mine, therefore, the cable that requirement is attached thereto possesses air guide, tension and jamproof characteristics simultaneously, makes cable in the transmission multi-channel electric signal, can pass through wireway transmission pressure displacement information again, and will guarantee can not broken because of the cable deadweight in the heavy duty service, not by the interference of electromagnetic field of down-hole.The applicant by retrieval and look into new, find no possess air guide simultaneously, the correlation technique report of tension, anti-interference characteristics cable.

Summary of the invention

The technical problem that the utility model solves: provide a kind of air guide tension anti-interference cable, the signal of telecommunication of can multiplexing gathering can directly be transferred to terminal with pressure, pressure information again.Can guarantee simultaneously under the big condition of pulling force such as deep-well, not broken, and can under the environment that circuit such as down-hole interlock, have very strong anti-electromagnetic field interference function by the cable deadweight.

Technical solution of the present utility model: the anti-interference cable of a kind of air guide tension, comprise wireway (1), insulation conductor wire core (2), insulation steel wire reinforced core (3) and sheath (6), wireway (1) is positioned at the cable center position vertically, the stranded vertically periphery in wireway (1) of insulation conductor wire core (2) and insulation steel wire reinforced core (3) forms the round cable core, the periphery of round cable core is enclosed with internal shield (4), be enclosed with outer shielding layer (5) on the internal shield (4), be enclosed with sheath (6) on the outer shielding layer (5).

Preferably six groups of insulation conductor wire cores (2) are symmetricly set on vertically the periphery of wireway (1), two groups of insulation steel wire reinforced cores (3) are symmetricly set on the periphery of wireway (1) vertically.

In order to improve the tensile strength of cable, also four groups of insulation conductor wire cores (2) can be symmetricly set on vertically the periphery of wireway (1), four groups of insulation steel wire reinforced cores (3) are symmetricly set on the periphery of wireway (1) vertically.

Advantage that the utlity model has and effect:

1, the utility model both can transmit multi-channel electric signal, can around the wireway strand system reinforcement steel wires that thoroughly do away with edge, make cable have stronger stretching resistance simultaneously by the wireway transmission pressure displacement information of cable center again more.

2, the utility model cable core adopts double-layer shielding structure, makes cable have good interference free performance under the interference source complex environments such as mine that circuit interlocks.

Embodiment:

1,2 first kind of embodiment of the present utility model described in conjunction with the accompanying drawings.

The anti-interference cable of a kind of air guide tension, comprise wireway (1), insulation conductor wire core (2), insulation steel wire reinforced core (3) and sheath (6), wireway (1) is positioned at the cable center position vertically, six groups of insulation conductor wire cores (2) are symmetricly set on the periphery of wireway (1) vertically, and two groups of insulation steel wire reinforced cores (3) are symmetricly set on the periphery of wireway (1) vertically.And the stranded vertically periphery in wireway (1) of insulation conductor wire core (2) and insulation steel wire reinforced core (3) forms the round cable core, the periphery of round cable core is enclosed with internal shield (4), be enclosed with outer shielding layer (5) on the internal shield (4), be enclosed with sheath (6) on the outer shielding layer (5).

Wherein, cable center's wireway (1) adopts the polyolefine material of intensity and good-toughness to extrude and forms, and is used for conducting pressure and changes.Along the central airway strand system six roots of sensation is the insulation conductor wire core (2) of tin-coated copper heart yearn, is used for conductive electrical current signal.Strand has been made two steel wire reinforced cores (3) that extruded insulating barrier simultaneously, increases the tensile strength of whole cable.Stranded for overlapping wrapped aluminium-plastic tape on the round cable core closely as internal shield (4), go up with zinc-plated circular copper wire braiding outer shielding layer (5) at internal shield (4), form powerful anti-interference layer of double shield.On screen, extrude good PVC sheath (6), constitute the desirable anti-interference sensor cable of air guide tension.

3,4 second kind of embodiment of the present utility model described in conjunction with the accompanying drawings.

The anti-interference cable of a kind of air guide tension, comprise wireway (1), insulation conductor wire core (2), insulation steel wire reinforced core (3) and sheath (6), wireway (1) is positioned at the cable center position vertically, four groups of insulation conductor wire cores (2) are symmetricly set on the periphery of wireway (1) vertically, and four groups of insulation steel wire reinforced cores (3) are symmetricly set on the periphery of wireway (1) vertically.And the stranded vertically periphery in wireway (1) of insulation conductor wire core (2) and insulation steel wire reinforced core (3) forms the round cable core, the periphery of round cable core is enclosed with internal shield (4), be enclosed with outer shielding layer (5) on the internal shield (4), be enclosed with sheath (6) on the outer shielding layer (5).The difference of second kind of embodiment and first kind of embodiment is the insulation steel wire reinforced core (3) of peripheral evenly distribute four eradication edge conductor wire cores (2) and four symmetric arrays of central airway (1), makes the tensile strength of cable higher.
