Description

Multi-core branch combination cable

Technical Field

The utility model relates to the technical field of cables, specifically be a multicore branch combination cable.

Background

A cable is generally a rope-like cable made up of several twisted conductors, each conductor being insulated from the other and usually twisted around a center, and surrounded by a highly insulating covering, characterized by an inner current-carrying and an outer insulation.

1. The existing cable is simple in internal structure, so that when external pressure is large or the cable is bent for a long time, a wire inside the cable is easy to damage, and the service life of the cable is further influenced.

2. When the existing cable works, the wire is easily affected by the outside, and when combustion occurs, the wire can be bonded, so that the combustion is severe, and the use safety is affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multicore branch combination cable to solve the problem of proposing among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a multicore branch combination cable, includes the packing layer, the inside of packing layer is provided with the support frame, the periphery and the center of support frame are provided with the cable core, the outside of cable core is provided with the shielding layer, the outside of support frame and shielding layer is located to the packing layer, the outside of packing layer is provided with the jam-proof layer, the outside on jam-proof layer is provided with the inoxidizing coating, the outside of inoxidizing coating is provided with adiabatic stratum reticulare, the outside on adiabatic stratum reticulare is provided with insulating filling layer, the outside of insulating filling layer is provided with the wearing layer.

Preferably, nine groups of cable cores are uniformly arranged inside the packaging layer, and grooves matched with the cable cores are formed in the outer side of the supporting frame.

Preferably, the shielding layer is formed by weaving tinned copper wires and aramid yarns.

Preferably, the inside of the protective layer is an alkali-free glass fiber layer.

Preferably, the low-smoke halogen-free wire protective sleeve of the insulating filling layer is nonagon.

Preferably, the TPU layer of the wear layer.

Compared with the prior art, the beneficial effects of the utility model are that:

1. this multicore branch combination cable for support frame, inoxidizing coating and the wearing layer that sets up through the cable core outside for when external pressure is great, improve the stability of cable core effectively, thereby can not make the inside wire of cable take place to damage, then the effectual life who prolongs the cable.

2. This multicore branch combination cable because the outside of support frame is provided with the recess with cable core looks adaptation for the multiunit cable core direct contact not then can not appear bonding phenomenon, reduces burning degree effectively, and is safe in utilization.

fig. 3 is an enlarged view of a portion a in fig. 2.

In the figure: 1. a packaging layer; 2. a support frame; 3. a cable core; 4. a shielding layer; 5. an interference prevention layer; 6. a protective layer; 7. a thermally insulating web layer; 8. an insulating filling layer; 9. and a wear-resistant layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: a multi-core branch combination cable comprises a packaging layer 1, a support frame 2 is arranged inside the packaging layer 1, cable cores 3 are arranged on the periphery and the center of the support frame 2, nine groups of cable cores 3 are provided, grooves matched with the cable cores 3 are arranged on the outer side of the support frame 2,

the outside of packaging layer 1 is provided with shielding layer 4, shielding layer 4 is woven for tinned copper wire and aramid yarn and forms, packaging layer 1 locates support frame 2 and shielding layer 4's the outside, packaging layer 1's the outside is provided with jam-proof layer 5, jam-proof layer 5's the outside is provided with inoxidizing coating 6, inoxidizing coating 6 is inside to be alkali-free glass fiber layer, the outside of inoxidizing coating 6 is provided with adiabatic stratum reticulare 7, adiabatic stratum reticulare 7's the outside is provided with insulating filling layer 8, insulating filling layer 8 is low smoke and zero halogen electric wire protection cover, and insulating filling layer 8's shape is the nonagon, insulating filling layer 8's the outside is provided with wearing layer 9, wearing layer 9's TPU layer.

The working principle is as follows: when using a multicore branch combination cable, when external pressure is great, support frame 2 through the 3 outside settings of cable core, inoxidizing coating 6 and wearing layer 9, make when external pressure is great, improve the stability of cable core 3 effectively, thereby can not make the inside wire of cable take place to damage, then the effectual life who prolongs the cable, when cable core 3 is in high temperature environment or when taking place the burning, because the outside of support frame 2 is provided with the recess with 3 looks adaptations of cable core, make multiunit cable core 3 not direct contact, then bonding phenomenon can not appear, reduce the degree of burning effectively, high safety in utilization.
