Abstract

The utility model discloses a kind of double insulation robots drag chain cables, including conductor core wire and sheath, there are three the conductor core wire is arranged altogether, the conductor core wire is socketed on inside the sheath, high-elastic PVC internal layer is enclosed on the outside of the conductor core wire, it is socketed with HDPE external insulation sleeve on the outside of the high-elastic PVC internal layer, the jacket inner wall is fitted with non-woven fabrics, PVC packing is additionally provided with inside the sheath.The utility model is suitable for robot drag chain cable, the cable uses double insulation effect, so that the insulation thickness of the cable and pressure-resistant performance are more secure, and this double insulating structure makes the cable play the stress buffering between insulating layer in bending motion process, greatly increase the bent number of product, while the cable can be used in the specific environment of Water-proof and oil-proof.

Description

A kind of double insulation robots drag chain cable

Technical field

The utility model belongs to field of cable technology, specially a kind of double insulation robots drag chain cable.

Background technique

Cable is usually every group by several or the cable of similar rope that several groups of conducting wires [every group at least two] are twisted Mutually insulated between conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation, and multi rack is located at In the air or it is mounted in underground, the bottom, it is defeated for telecommunication or electric power；

And robot drag chain cable is a kind of cable for robot drag chain, since robot is needed some special It is used in environment, to the more demanding of cable, existing cable mostly uses greatly single layer dielectrics structure, and insulating properties, waterproofness are inadequate, And the flexural strength of Integral cable is also difficult to meet demand.

Utility model content

Utility model aims to solve the problems in background techniques, provide a kind of double insulation robots drag chain electricity Cable.

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

A kind of double insulation robots drag chain cable, including conductor core wire and sheath, there are three the conductor core wire is arranged altogether, The conductor core wire is socketed on inside the sheath, is enclosed with high-elastic PVC internal layer, the high-elastic PVC on the outside of the conductor core wire It is socketed with HDPE external insulation sleeve on the outside of internal layer, the jacket inner wall is fitted with non-woven fabrics, is additionally provided with PVC inside the sheath and fills out Fill item.

Wherein, there are three the PVC packing is arranged altogether, and three PVC packings are placed equidistant with.

Wherein, the outer wall of the HDPE external insulation sleeve on the conductor core wire is tangent two-by-two, and three are stated conductor core wire On the HDPE external insulation sleeve simultaneously it is tangent with the jacket inner wall.

Wherein, the outer wall of the PVC packing simultaneously with it is exhausted outside the HDPE on two adjacent conductor core wires It is tangent and tangent simultaneously with the jacket inner wall that edge covers outer wall.

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

The cable uses double insulation effect, so that the insulation thickness of the cable and pressure-resistant performance are more secure and this Double insulating structure makes the cable play the stress buffering between insulating layer in bending motion process, makes bent time of product Number greatly increases；

The cable on the outside of conductor core wire by being enclosed with high-elastic PVC internal layer, the height that high-elastic PVC internal layer has due to itself Elasticity passes through so that the shearing resistance compression strength of the cable is bigger, and is socketed with HDPE external insulation sleeve on the outside of high-elastic PVC internal layer The effect of HDPE external insulation sleeve is so that the water-proof and oil-proof performances of the cable are stronger, so that the cable can be in Water-proof and oil-proof Specific environment use.

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, a kind of double insulation robots drag chain cable, including conductor core wire 6 and sheath 1, conductor core wire 6 are arranged altogether There are three, conductor core wire 6 is socketed on inside sheath 1, and high-elastic PVC internal layer 5, high-elastic PVC internal layer 5 are enclosed on the outside of conductor core wire 6 Outside is socketed with HDPE external insulation sleeve 4, and 1 inner wall of sheath is fitted with non-woven fabrics 2, PVC packing 3 is additionally provided with inside sheath 1, this The structure setting of sample makes to fill the more rounding for closely cable appearance being allowed to do between cable insulation core wire, and moves the cable in bending The stress buffering between insulating layer is played in the process, and the bending number of product is made to reach 25,000,000 times or more, while the cable By being enclosed with high-elastic PVC internal layer 5 on the outside of conductor core wire 6, high-elastic PVC internal layer 5 has high resiliency due to itself, so that the electricity The intensity of cable is stronger, and is socketed with HDPE external insulation sleeve 4 on the outside of high-elastic PVC internal layer 5, is made by the effect of HDPE external insulation sleeve 4 The water-proof and oil-proof performances for obtaining the cable are stronger, so that the cable can be used in the specific environment of Water-proof and oil-proof.

There are three PVC packing 3 is arranged altogether, and three PVC packings 3 are placed equidistant with.

The outer wall of HDPE external insulation sleeve 4 on three conductor core wires 6 is tangent two-by-two, and three are stated on conductor core wire 6 HDPE external insulation sleeve 4 simultaneously it is tangent with 1 inner wall of sheath, such structure setting make be between three 6 central points of conductor core wire An existing equilateral triangle structure is hardly damaged so that the intensity of the cable is bigger.

The outer wall of PVC packing 3 is tangent with 4 outer wall of HDPE external insulation sleeve on two adjacent conductor core wires 6 simultaneously, and It is tangent simultaneously with 1 inner wall of sheath.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
