Description

Cellular-type silicon rubber glass fibre sleeve

Technical field

The utility model relates to a kind of casing, especially a kind of cellular-type silicon rubber glass fibre sleeve.

Background technique

In the industrial production, casing using very extensive, cable rope sleeve provides very heavy for the normal operation of cable The effect wanted.In the products such as automobile, shipbuilding, motor, household electrical appliances, it is often necessary to using casing to the various harness of interiors of products into Row protective separation.Casing in application process, due to that can generate a large amount of heat in the cable course of work, heat be difficult in time from It is distributed in casing, further will cause the raising of inside pipe casing temperature, when the cable of inside pipe casing has two beams, the set of high temperature Pipe internal environment can there are hidden danger for security to the two bunch cables directly contacted, or even generate melting to the insulation covering of cable It destroys, safety is lower, in addition, prolonged hot environment can reduce the service life of casing and cable, it is difficult to meet practical Requirement in.

It is lacked in view of this, the purpose of this utility model is to provide a kind of new technical solutions with solving existing technology It falls into.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of cellular-type silicon rubber glass fibre sleeve, solution Having determined existing casing there are heat dissipation performances, poor, there are the technological deficiencies such as security risk, service life is short.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of cellular-type silicon rubber glass fibre sleeve, including the first silastic-layer are set inside first silastic-layer It is equipped with the first inside silicone tube and the second inside silicone tube, is had between first inside silicone tube and the second inside silicone tube Internal separate space, the first fiberglass braided layer is enclosed with outside first silastic-layer, and first glass fibre is compiled It is enclosed with layer of polyurethane outside tissue layer, electro-insulating rubber layer, packet outside the electro-insulating rubber layer are enclosed with outside the layer of polyurethane It is wrapped with the second fiberglass braided layer, is enclosed with Teflon adhesive tape layer outside the second fiberglass braided layer.

As a further improvement of the above technical scheme, the described first fiberglass braided layer and second fiberglass braided Layer is alkali-free glass fibre braiding layer.

As a further improvement of the above technical scheme, the described first fiberglass braided layer and second fiberglass braided Layer is internal to be embedded with tensile steel wire.

As a further improvement of the above technical scheme, the annular that the layer of polyurethane is internally embedded annular winding is reinforced Rope.

As a further improvement of the above technical scheme, first inside silicone tube and second inside silicone tube it Between there is first partition and second partition, gap between the first partition and second partition is above-mentioned inside every absolutely empty Between.

As a further improvement of the above technical scheme, the section inner hole of first silastic-layer is kidney slot, described First inside silicone tube and the second inside silicone tube are located at the both ends of the kidney slot.

As a further improvement of the above technical scheme, the internal diameter of first inside silicone tube and the second inside silicone tube It is 10-13mm.

The beneficial effects of the utility model are: the utility model provides a kind of cellular-type silicon rubber glass fibre sleeve, This kind of cellular-type silicon rubber glass fibre sleeve is being internally provided with internal clearance space, by internal clearance space can rapidly by The heat that cable generates when working takes rapidly casing out of, avoids casing heating excessively high, guarantees cable within the scope of suitable temperature Work, not only improves safety, while also effectively extending the service life of casing and cable；In addition, empty by internal interval Between two bunch cables are separated, avoiding cable, covering is impaired under high temperature environment and contact short circuit, further promotes safety, avoids There is security risk.

That in short, this kind of cellular-type silicon rubber glass fibre sleeve solves existing casing, there are heat dissipation performances is poor, there is peace The technological deficiencies such as full hidden danger, service life is short.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the cross section structure schematic diagram of the utility model.

Specific embodiment

It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection It encloses.In addition, all connection/connection relationships being related in patent, not singly refer to that component directly connects, and referring to can be according to specific Performance, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each skill in the utility model creation Art feature, can be with combination of interactions, referring to Fig.1 under the premise of not conflicting conflict.

A kind of cellular-type silicon rubber glass fibre sleeve, including the first silastic-layer 1, inside first silastic-layer 1 It is provided with the first inside silicone tube 11 and the second inside silicone tube 12, first inside silicone tube 11 and the second inside silicone tube There is internal separate space 13 between 12, be enclosed with the first fiberglass braided layer 2 outside first silastic-layer 1, it is described It is enclosed with layer of polyurethane 3 outside first fiberglass braided layer 2, electro-insulating rubber layer 4, institute are enclosed with outside the layer of polyurethane 3 It states and is enclosed with the second fiberglass braided layer 5 outside electro-insulating rubber layer 4, be enclosed with outside the second fiberglass braided layer 5 Teflon adhesive tape layer 6.
