Description

A kind of PVC insulation strand molded line

Technical field

The utility model belongs to technical field of electric wires and cables, is related to a kind of PVC insulation strand molded line.

Background technology

Twisted wire is realized around the rotation of twisted wire axis constant angular velocity and twisted wire at the uniform velocity forward travel with twisted single line.Suitable for work Working frequency is higher, and excessive occasion is lost in the kelvin effect and kindred effect of sub-thread wire rod.It can make running temperature using twisted wire It reduces, compared to the single cord with sectional area, twisted wire possesses higher mechanicalness, flexibility.

Existing twisted wire, it is contemplated that the phase is flexible, and abandons its more important mechanical performance, such as tension, buckle resistance It can wait, be not suitable for ground and be laid with, if receiving larger impact force, it is possible to create core bending is impaired.

Utility model content

The purpose of this utility model is the existing above problem in view of the prior art, provides a kind of PVC insulation and twists molded line, Technical problem to be solved in the utility model is how to improve the mechanical performance of twisted wire, such as buckle resistance can.

The purpose of this utility model can be realized by following technical proposal：A kind of PVC insulation strand molded line, feature exist In this insulation twists the sheath that molded line includes both threads core and a package core, this strand molded line further includes a S-type isolation Item, in the shape of a spiral, there are two the recess being distributed with the central symmetry of sheath, both threads for the upper tool of the isolating bar for the isolating bar Core is separately fixed in recess, dense layer is filled between the isolating bar and sheath, for fixing core, sheath and isolation Item.

Both threads core can not only be isolated in the effect of isolating bar, make insulation performance between the two, thermal insulation performance, Anti- short-circuit capability is strengthened, but also can improve the entire intensity for twisting molded line, makes entirely to twist molded line on any direction Compression strength, to improve twist molded line mechanical performance, bend resistance, tensile property get a promotion.

In a kind of above-mentioned PVC insulation twists molded line, the isolating bar is aluminum thin slice.

Aluminum thin slice can realize shielding between two cores, and can be improved under the premise of not influencing pliability Mechanical performance.

In a kind of above-mentioned PVC insulation twists molded line, rubber package fibre bundle forms the isolating bar.

The setting of fibre bundle, can improve the tensile capacity for twisting molded line, and the direction of fibre bundle is consistent with the direction of core.

In a kind of above-mentioned PVC insulation twists molded line, the core is wrapped with spool.

In a kind of above-mentioned PVC insulation twists molded line, the sheath is made of resin material.

Description of the drawings

Fig. 1 is the sectional view of this strand molded line.

In figure, 1, core；2, sheath；3, isolating bar；4, dense layer；5, spool.

Specific implementation mode

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figure 1, this insulation twists the sheath 2 that molded line includes both threads core 1 and a package core 1, this strand molded line is also Including a S-type isolating bar 3, in the shape of a spiral, there are two be distributed with the central symmetry of sheath 2 for the upper tool of isolating bar 3 for isolating bar 3 Recess, both threads core 1 is separately fixed in recess, dense layer 4 is filled between isolating bar 3 and sheath 2, for fixing core 1, sheath 2 and isolating bar 3.

Both threads core 1 can not only be isolated in the effect of isolating bar 3, make insulation performance between the two, heat-insulated character Energy, anti-short-circuit capability are strengthened, but also can improve the entire intensity for twisting molded line, make entirely to twist molded line with any direction On compression strength, to improve twist molded line mechanical performance, bend resistance, tensile property get a promotion.

Isolating bar 3 is aluminum thin slice；Aluminum thin slice can realize shielding between two cores 1, and can not influence Under the premise of pliability, mechanical performance is improved.

Rubber wraps up fibre bundle and forms isolating bar 3；The setting of fibre bundle can improve the tensile capacity for twisting molded line, fiber The direction of beam is consistent with the direction of core 1.

Core 1 is wrapped with spool 5；Sheath 2 is made of resin material.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
