Description

A kind of decompression cable

Technical field:

The utility model relates to fields, and in particular to a kind of decompression cable.

Background technique:

Cable is usually the cable of similar rope as several or made of several groups of wire strandings, between every group of conducting wire mutually absolutely Edge, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Multi rack is located at aerial or is mounted in ground Under, it is water-bed, be used for telecommunication or power Transmission.

Cable is all simply to twist together cable conductor, then put on protective case during the manufacturing at present, But in cable after laying, often because external environment is by different degrees of impact and collision, formed between internal cable core Hard squeeze can cause to damage, reduce the service life of cable to conductor for a long time.

Utility model content:

The technical problem to be solved by the utility model is to provide a kind of structure is simple, safe and reliable decompression cable.

The following technical solution is employed for technical problem to be solved in the utility model to realize:

A kind of decompression cable, including cable core, sheath, aluminium alloy armored layer, fire-retardant surrounding layer, every group of cable core is by interior Outward successively include conductor, the mica tape outside conductor, the rubber insulation outside mica tape, described every group Elastic rubber set is arranged with outside cable core, and the internal diameter of elastic rubber set is greater than the outer diameter of the cable core, the multiple groups Cable core is located in the inner cavity of the sheath, and the aluminium alloy armored layer, the aluminium alloy armour are coated with outside the sheath The fire-retardant surrounding layer is coated with outside dress layer.

Further, the reinforcing rib in the same direction with the cable core is disposed in the inner cavity of the sheath.

Further, the reinforcing rib is set at the center of the sheath inner cavity.

Further, the positive stop strip in the same direction with the conductor is provided in the inner cavity of the sheath, the positive stop strip is inserted It is placed in the gap between the elastic rubber set.

Further, liner layer is provided between the sheath and aluminium alloy armored layer.

The beneficial effects of the utility model are: the utility model structure is simple, securely and reliably, by the outer of every group of cable core Portion is arranged elastic rubber set, and the internal diameter of elastic rubber set is greater than the outer diameter of cable core, so that cable is by applied external force Extruding when, the elastic rubber set outside cable core, which can be offset, slows down applied external force, avoids cable core by biggish effect Power and cause interior damage, effectively extend the service life of cable.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of decompression cable provided by the utility model；

Wherein: 1- cable core；2- sheath；3- aluminium alloy armored layer；The fire-retardant surrounding layer of 4-；5- conductor；6- mica tape；7- Rubber insulation；8- elastic rubber set；9- reinforcing rib；10- positive stop strip；11- liner layer.

Specific embodiment:

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.

Embodiment 1:

As shown in Figure 1, a kind of decompression cable, including cable core 1, sheath 2, aluminium alloy armored layer 3, fire-retardant surrounding layer 4, institute Stating every group of cable core 1 from inside to outside includes successively conductor 5, the mica tape 6 outside conductor 5, outside mica tape 6 Rubber insulation 7 is arranged with elastic rubber set 8 outside every group of cable core 1, and the internal diameter of elastic rubber set 8 is greater than The outer diameter of the cable core 1, the multiple groups cable core 1 are located in the inner cavity of the sheath 2, coat outside the sheath 2 Aluminium alloy armored layer 3 is stated, the fire-retardant surrounding layer 4 is coated with outside the aluminium alloy armored layer 3.

Further, the reinforcing rib 9 in the same direction with the cable core 1, elastic reinforcement muscle are disposed in the inner cavity of the sheath 2 9 can reinforce the intensity of entire cable, have certain protective effect to cable.

Further, the reinforcing rib 9 is set at the center of 2 inner cavity of sheath, which can make entirely Cable strength reasonable Arrangement, is uniformly distributed.

Embodiment 2:

Further, the positive stop strip 10 in the same direction with the conductor 5, the limit are provided in the inner cavity of the sheath 2 Item 10 is inserted in the gap between the elastic rubber set, and the setting of positive stop strip 10 can limit cable core, avoid cable Pernicious abrasion is formed between core 1.

Further, liner layer 11, the setting of liner layer 11 are provided between the sheath 2 and aluminium alloy armored layer 3 Sheath 2 directly can be squeezed and be collided to avoid aluminium alloy armored layer 3, form effective protection.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
