Abstract

The utility model discloses a sheath flexible cable which comprises a plurality of guide cores, wherein winding layers are coated outside the guide cores, and the winding layers are sequentially provided with a water blocking buffer layer, a shielding layer and a sheath from inside to outside. The sheath flexible cable has a simple structure and is convenient to use, the sheath is arranged on the surface of the cable, so that the cable can still maintain good transmission efficiency after being bent for many times, meanwhile, the water-blocking buffer layer is arranged, so that water can be prevented from leaking to the guide core, and the service life and the transmission efficiency of the cable are improved.

Description

Sheath flexible cable

Technical Field

The utility model relates to the technical field of cables, in particular to a sheath flexible cable.

Background

The cable is typically a rope-like cable stranded from several wires or groups of wires (at least two in each group), each group being insulated from each other and often twisted around a center, with a highly insulating coating over the entire outer surface. The cable has an inner energized, outer insulated feature.

The existing cable is generally coated on the outer sides of the groups of wires by rubber, so that the cable can be suitable for most daily life scenes, but the surface of the cable is easy to damage under the condition of repeated bending, and the transmission efficiency is reduced.

Based on the above situation, the utility model provides a sheath flexible cable which can effectively solve the above problems.

Disclosure of Invention

The utility model aims to provide a sheath flexible cable. The sheath flexible cable has a simple structure and is convenient to use, the sheath is arranged on the surface of the cable, so that the cable can still maintain good transmission efficiency after being bent for many times, meanwhile, the water-blocking buffer layer is arranged, so that water can be prevented from leaking to the guide core, and the service life and the transmission efficiency of the cable are improved.

The utility model is realized by the following technical scheme:

the utility model provides a sheath flexible cable, includes a plurality of guide core, guide core outer package has the winding layer, the winding layer is equipped with buffer layer, shielding layer and sheath that blocks water from inside to outside in proper order.

Preferably, a thermochromic layer is arranged on the outer side of the sheath.

Preferably, the fire-proof layer is coated on the guide core.

Preferably, the insulating layer is coated on the outer side of the fireproof layer.

Preferably, a filler is arranged between the guide core and the winding layer.

Preferably, the number of the guide cores is three.

Compared with the prior art, the utility model has the following advantages:

the sheath flexible cable has a simple structure and is convenient to use, the sheath is arranged on the surface of the cable, so that the cable can still maintain good transmission efficiency after being bent for many times, meanwhile, the water-blocking buffer layer is arranged, so that water can be prevented from leaking to the guide core, and the service life and the transmission efficiency of the cable are improved.

Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the present patent; for the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationship depicted in the drawings is for illustrative purposes only and is not to be construed as limiting the present patent.

Example 1:

as shown in fig. 1, the utility model provides a sheath flexible cable, which comprises a plurality of guide cores 1, wherein the guide cores 1 are externally coated with a winding layer 2, and the winding layer 2 is sequentially provided with a water-blocking buffer layer 3, a shielding layer 4 and a sheath 5 from inside to outside.

Example 2:

The outer side of the sheath 5 is provided with a thermochromic layer 6.

The temperature state of the cable can be prompted by the temperature-sensitive color-changing layer 6, and the temperature-sensitive color-changing layer 6 changes color due to temperature rise.

Further, in another embodiment, the conducting core 1 is coated with a fireproof layer 7.

The fireproof layer 7 is arranged, so that the flame retardant effect can be further improved, and the damage of the guide core 1 and the influence on the transmission efficiency are avoided.

Further, in another embodiment, the fireproof layer 7 is coated with an insulating layer 8.

The insulating layer 8 is arranged to insulate the guide core 1 from the outside, so that the influence of the outside on the guide core 1 is avoided.

Further, in another embodiment, a filler 9 is provided between the guide core 1 and the winding layer 2.

The filler 9 may be fireproof asbestos or the like, further improving the fireproof effect.

Further, in another embodiment, the number of the guide cores 1 is three.

The jacketed flexible cable of the present utility model can be readily manufactured or used by those skilled in the art from the description of the present utility model and the accompanying drawings, and can produce the positive effects described in the present utility model.
