Abstract

The utility model relates to the technical field of cables, specifically be a combined type cable, including cable sheathing, cable sheathing's inboard sets up the buffer tube around the axis, cable sheathing and buffer tube body coupling, all support in the inboard cartridge of buffer tube and expect, the inboard fixed setting that props that expects in the interior props the pipe layer, prop the inboard installation cable core on pipe layer. The utility model discloses in, not only the production degree of difficulty is low, and is with low costs moreover, but the buffering resistance to compression protective properties of cable spare is fabulous, and the cable core is difficult for receiving external force and destroys, and the buffer tube can only warp and can not shift position, makes things convenient for its reconversion, and interior support piece still has the supporting role to the buffer tube moreover, restricts the indent degree of cable sheath and buffer tube, effectively protects the cable core.

Description

Composite cable

Technical Field

The utility model relates to the technical field of cables, specifically a combined type cable.

Background

Present combined type cable improves the protection mode to the cable core and mainly adds the layer design for outside, through the mode that increases progressively layer by layer, reaches a buffer protection to the cable core, and such design not only inconvenient production has improved the overall cost of cable moreover, and some layers add not so well moreover, and a lot of cable production equipment now do not possess the condition that the production added yet.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a combined type cable to propose the inconvenient production of present cable core protection design in solving above-mentioned background art, improved the problem of the overall cost of cable moreover.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a combined type cable, includes the cable sheathing, the inboard of cable sheathing sets up the buffer tube around the axis, the cable sheathing is connected with buffer tube an organic whole, all the inboard cartridge of buffer tube is interior to be propped the piece, the inboard fixed setting that props the piece props the pipe layer, prop the inboard installation cable core on pipe layer.

As a further description of the above technical solution:

the cable sheath and the buffer tubes are made of the same material, and the adjacent buffer tubes are arranged in a contact mode.

As a further description of the above technical solution:

the surface of the inner supporting piece contacted with the buffer pipe is of a continuous arc-shaped concave structure.

Compared with the prior art, the utility model provides a combined type cable possesses following beneficial effect:

1. in the utility model, the traditional mode of overlapping and cladding various protective layers is not adopted to design the cable element, and the structure of supporting layer by layer is adopted to design the cable element, the supporting tube layer supports the inner supporting piece, the inner supporting piece supports the buffer tube and limits the buffer tube, the cable sheath and the buffer tube are connected integrally, the body has the effect of mutual supporting, the cable has low production difficulty and low cost, but the buffer compression-resistant protective performance of the cable element is excellent, and the cable core is not easy to be damaged by external force;

2. the utility model discloses in, interior support piece is the interior concave structure of continuous arc with the face that the buffer tube contacted, and interior support piece's interior concave department is spacing with the buffer tube, changes the moving direction of buffer tube for the buffer tube can only warp and can not the shift position, makes things convenient for its reconversion, and interior support piece still has the supporting role to the buffer tube in addition, limits the indent degree of cable sheath and buffer tube, effectively protects the cable core.

FIG. 1 is a schematic view of the present invention;

fig. 2 is a schematic view of the structure of the connector of the cable sheath and the buffer tube of the present invention.

Illustration of the drawings:

1. a cable jacket; 2. a buffer tube; 3. an inner support member; 4. a tube supporting layer; 5. a cable core.

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 efforts all belong to the protection scope of the present invention.

Example (b):

referring to fig. 1-2, the present invention provides a composite cable, which includes a cable sheath 1, a buffer tube 2 is disposed around an axis inside the cable sheath 1, the cable sheath 1 is integrally connected to the buffer tube 2, all the buffer tubes 2 are inserted into an inner supporting member 3, a tube supporting layer 4 is fixedly disposed inside the inner supporting member 3, and a cable core 5 is disposed inside the tube supporting layer 4.

Specifically, as shown in fig. 1 and 2, the cable sheath 1 and the buffer tubes 2 are made of the same material, and adjacent buffer tubes 2 are arranged in a contact manner, so that the production is convenient, and the buffer tubes 2 can be mutually supported.

Specifically, as shown in fig. 1, the contact surface of the inner support member 3 and the buffer tube 2 is a continuous arc-shaped concave structure, which has two functions of supporting and limiting the buffer tube 2.

The working principle is as follows:

firstly, a connector of a cable sheath 1 and a buffer tube 2 (an existing cable sheath piece is adopted, generally a polyurethane sheath or a polyethylene sheath and the like) is produced, the connector is an external protective layer, because adjacent buffer tubes 2 are contacted with each other, the buffer tubes 2 and the buffer tubes 2 are mutually supported, and the buffer tubes 2 are provided with cavities, so that the connector of the cable sheath 1 and the buffer tubes 2 is a protective layer with a very good buffer effect, the external stress, the automatic deformation and the automatic rebound recovery are realized, an inner support piece 3 (cable rubber or other materials can be selected and can be selected according to different functional requirements) is designed on the inner side of the buffer tubes 2, a support tube layer 4 (rubber tubes or other materials can be selected and can be selected according to different functional requirements) is designed on the inner side of the inner support piece 3, and the support tube layer 4 plays a role in supporting and stabilizing the inner support piece 3, interior support piece 3 plays a steady effect of support to cable sheathing 1 and buffer tube 2 again, and interior support piece 3 and buffer tube 2 have a spacing effect of antiskid taking off, the position of buffer tube 2 has been restricted by interior support piece 3, buffer tube 2 can inwards be out of shape, but can not remove about, buffer tube 2 rebounds reconversion just more smoothly like this, and interior support piece 3 and cable sheathing 1 between the interval great, cable sheathing 1 and buffer tube 2 receive the injury like this, interior support piece 3 can not receive the injury, all adorn cable core 5 and prop the pipe layer 4 inboardly, cable core 5 can not receive external force damage.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
