Anti cable of grinding installation of being convenient for

Technical Field

The utility model relates to a cable technical field especially relates to an anti cable of being convenient for installation that grinds.

Background

Along with the continuous development of the information era, the communication cable is more and more widely used, the cable wiring environment is more and more complicated, the conventional communication cable is poor in rolling resistance generally, the cable needs to be frequently peeled and installed during wiring installation, the line sequence is manually identified according to the line color, and the construction efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem, it is not enough to the technique that above-mentioned exists, provides an anti cable of grinding the installation of being convenient for, adopts heart yearn position asymmetric fixed arrangement in the cable to be triangle-shaped, but need not discern the line preface and directly to work a telephone switchboard, sets up the buffer hole in the filling layer to set up the anti ability of grinding of ripple sheath further strengthened the cable in the outside of cable.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a resist and grind cable of installation of being convenient for, includes heart yearn and line skin, its characterized in that: the core wire positions are asymmetrically fixedly arranged in the cable to form a triangle, a filling layer is arranged between the core wires, and a buffer hole is formed in the filling layer. Asymmetric arrangement can avoid the cable to connect the mistake when the cable installation, sets up the buffer hole of filling layer, can cushion external force extrusion and cause mechanical damage to the heart yearn.

Further optimize this technical scheme, the filling layer outside is provided with the insulating layer, it has metal framework to encircle in the insulating layer. The metal framework arranged can play a role in shielding external interference and can strengthen the structural strength of the insulating layer.

Further optimizing the technical scheme, the insulating layer is made of butadiene rubber. The high elasticity of the butadiene rubber insulating layer can better absorb the rolling of external force on the cable.

Further optimizing the technical scheme, the metal framework is in an annular wavy shape. So that the metal framework has certain supporting capacity.

Further optimizing the technical scheme, the sectional area of the buffer hole accounts for 0.25-0.35% of the total area of the filling layer. The optimal buffering effect is achieved by setting the reasonable area of the buffering holes.

Further optimize this technical scheme, the outermost side of cable is provided with the ripple sheath. The corrugated sheath can resist certain external force and has certain flexibility.

Further optimize this technical scheme, the concave place equipartition of ripple sheath has oval through-hole. The fixing of the special terminal is convenient for the installation of the cable through the arranged oval through hole.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: with reference to fig. 1-2, a crush-resistant cable for easy installation, comprising a core wire 1 and a sheath 2, characterized in that: the cable is characterized in that three core wires 1 are arranged, the positions of the core wires 1 are asymmetrically fixedly arranged in a triangular shape in the cable section, filling layers 3 are arranged among the core wires 1, and buffer holes 301 are formed in the filling layers 3. The sectional area of the buffer hole 301 accounts for 0.25-0.35% of the total area of the filling layer 3. An insulating layer 4 is arranged on the outer side of the filling layer 3, the insulating layer 4 is made of butadiene rubber, and an annular wavy metal framework 5 is arranged in the insulating layer 4 in a surrounding mode. The outermost side of the cable is provided with a corrugated sheath 6. Oval through holes 601 are uniformly distributed in the concave positions of the corrugated sheath 6.

When the cable is used, as shown in fig. 1-2, the asymmetric fixed arrangement of the positions of the core wires 1 in the cable section is a triangle, the arrangement of the terminals connected with the cable and the arrangement of the core wires 1 present a mirror image relationship, when the cable is not correctly installed in the terminal, the terminals cannot be installed normally due to the asymmetry of the wire sequence, and the trouble of manually confirming the wire sequence during installation is avoided. The fixing of the dedicated terminal at the time of cable installation can be facilitated by the oval through hole 601 provided in the corrugated sheath 6.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
