Description

Cable with anti-aging outer layer and good bending performance

Technical Field

The utility model relates to the technical field of cables, concretely relates to cable with anti-aging is outer and the performance of buckling is good.

Background

Cables are made of one or more mutually insulated conductors and an outer insulating sheath that carries power or information from one point to another.

The currently used cables, no matter under what kind of construction environment, need to consider the following problems: 1. the outer side of the cable, which is in contact with air, is easy to oxidize, age and crack, so that the use safety is influenced; 2. in the process of drawing, repeated bending can cause the problem that the conductor of the inner layer is broken.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the problem that leads to the conductor rupture when avoiding the ageing of how to avoid or delay the cable and buckling for the solution, the utility model provides a cable with anti-aging skin and the good performance of buckling.

The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:

the utility model provides a cable with anti-aging is outer and the performance of buckling is good, includes rubber circle strip, rubber circle strip external screw thread is around being equipped with the conductor, the conductor wraps up outward has the insulating layer, the outer parcel of insulating layer has moisture barrier, moisture barrier wraps up outward has the anti-aging layer.

Further, the anti-aging layer comprises an outer wrapping layer, and a wax layer is smeared on the inner side of the outer wrapping layer.

Further, the outer wrapping layer is made of butyl rubber, and a wax-coated grid groove is formed in the outer wall of the outer wrapping layer.

Furthermore, the wax layer and the wax coated in the grid grooves both adopt rubber protective wax.

Furthermore, the moisture-proof layer is made of a PVC material.

The utility model has the advantages as follows:

1. the utility model discloses a wind the conductor screw thread and establish on rubber circle, when the cable is buckled, rubber circle is at first buckled, and the conductor is buckled after that, when the conductor is buckled, can draw in the rubber circle to dodge when buckling, and then avoid the conductor to be broken, the insulating layer of inlayer can be protected to outer ageing resistance layer simultaneously, thereby avoids the insulating layer ageing to break and causes the safety problem.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.

As shown in fig. 1 and fig. 2, a cable with anti-aging outer layer and good bending performance includes a rubber round bar 1, an outer thread of the rubber round bar 1 is wound with a conductor 2, an insulating layer 3 is wrapped outside the conductor 2, a moisture-proof layer 4 is wrapped outside the insulating layer 3, an anti-aging layer 5 is wrapped outside the moisture-proof layer 4, in some embodiments, the conductor 2 is wound on the rubber round bar 1 through a thread, when the cable is bent, the rubber round bar 1 is firstly bent, then the conductor 2 is bent, when the conductor 2 is bent, the conductor can be pulled into the rubber round bar 1, so as to avoid the conductor 2 from being broken, and meanwhile, the outer anti-aging layer 5 can protect the insulating layer 3 of the inner layer, so as to avoid the insulating layer 3 from being aged and broken to cause safety problems, more specifically: as shown in fig. 2, when rubber circle strip 1 buckles, conductor 2 buckles and can not buckle like rubber circle strip 1, the mode of buckling of rubber circle strip 1 is breakable, but conductor 2 can be tied into in rubber circle strip 1 when buckling, make it carry out dodging of certain degree, and then great possibility of having avoided conductor 2 to break when buckling, the entering of steam has been avoided under the protection of moisture proof layer 4 simultaneously, under the parcel of ageing resistant layer 5, the contact with oxygen has been avoided, and then the ageing of insulating layer 3 has been delayed or avoided.

As shown in fig. 1, in some embodiments, the anti-aging layer 5 includes an outer wrapping layer 501, and a wax layer 502 is coated on the inner side of the outer wrapping layer 501, where the wax layer 502 can wrap the inner moisture-proof layer 4 and the insulating layer 3 to avoid contact with water vapor and oxygen, thereby avoiding aging.

As shown in fig. 1, in some embodiments, the outer wrapping layer 501 is made of butyl rubber and the outer wall is configured with wax-coated grid grooves 503, the butyl rubber has heat resistance, ozone resistance, aging resistance, chemical resistance and waterproof performance, and when the grid grooves 503 are used for coating wax, the wax can be ensured to be adhered to the outer side of the outer wrapping layer 501.

As shown in fig. 1, in some embodiments, the wax layer 502 and the wax coated in the grid groove 503 are made of rubber protective wax, and the rubber protective wax has the effects of resisting ozone, sunlight, aging and the like, so that the service life of the outer wrapping layer 501 can be prolonged.

As shown in fig. 1, in some embodiments, the moisture barrier layer 4 is made of PVC, which has waterproof, moisture-proof, flame retardant, and heat insulation properties, and can protect the inner conductor 2 well, so as to achieve a basic waterproof function.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
