[0002] Communication cables are used to transmit telephone, telegraph, fax documents, television and radio programs, data and other electrical signals. Flexible cables are a type of cable. The conductor structure of flexible cables is mainly based on the twisted copper conductor structure of DIN VDE 0295 and IEC 228 standards. The sheath is mostly made of low-viscosity, flexible and wear-resistant materials to reduce the wear rate of the cable during continuous reciprocating movement.

[0003] However, it still has the following disadvantages in actual use:

[0004] During the use of existing flexible communication cables, after the cables are wired and installed, multiple cables are laid out in the same space, but are placed irregularly with respect to each other, the wiring is relatively scattered, which increases the safety risk and the subsequent inspection and maintenance are also relatively cumbersome. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-core communication cable with good flexibility to solve the problem raised in the above-mentioned background technology that, during the use of existing flexible communication cables, after the cables are wired and installed, multiple cables are laid out in the same space, but are in an irregular arrangement with respect to each other, the wiring is relatively scattered, the safety risk is increased, and the subsequent inspection and maintenance are also relatively cumbersome.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a multi-core communication cable with good flexibility, comprising:

[0008] Flexible cable body;

[0009] A regular connection part, wherein the regular connection includes a regular connection frame, a limit block, and a plugging head;

[0010] The regular connection frame is equidistantly sleeved and connected to the outer surface of the flexible cable body, and the limit blocks are equidistantly arranged on the outer surface of the regular connection frame, and the blocking head is dampingly connected to the middle part of one end of the limit block.

[0011] Furthermore, arc-shaped grooves are equidistantly provided in the middle of the outer surface of the regular connecting frame, and a second magnetic sheet is bonded to the outer surface of the limit block, and the second magnetic sheet is fixed to the inner wall of the arc-shaped groove by magnetic attraction.

[0012] Furthermore, the end of the limit block is bonded and connected with a first magnetic sheet, and the upper and lower groups of the first magnetic sheets have opposite magnetic properties.

[0013] Furthermore, the flexible cable body comprises an outer sheath, an armored steel tape, an inner sheath, a reinforcing steel column, and a metal conductor;

[0014] The armored steel belt is arranged on the inner wall of the outer sheath, and the inner sheath is located on the inner side of the armored steel belt. Reinforced steel columns are equidistantly arranged between the armored steel belt and the inner sheath, and metal conductors are equidistantly arranged on the inner side of the inner sheath.

[0015] Furthermore, a filling material layer is filled between adjacent reinforced steel columns, inner sheaths and metal conductors.

[0016] Furthermore, the outer wall of the metal conductor is wrapped with a shielding layer, and the outer wall of the shielding layer is wrapped with an insulating layer.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] The utility model arranges a plurality of regular connecting frames equidistantly on the outer surface of the flexible cable body, and cooperates with a plurality of limit blocks arranged on the outer surface to limit the structure of the remaining flexible cable bodies connected in the wiring, so as to avoid the multiple flexible cable bodies in the same space being scattered, increasing the safety risk and affecting the progress of subsequent inspection and maintenance. At the same time, a magnetic connection method is adopted between the limit blocks and the regular connecting frames, which can be conveniently disassembled and assembled. After the disassembled set of limit blocks are fixed by magnetic attraction, a sealing head is used in combination to provide external shielding and protection for the exposed end of the flexible cable body in the wiring, thereby improving the structural applicability.

[0019] Based on the above beneficial effects, under the protection of the armored steel belt of the flexible cable body itself, multiple reinforced steel columns arranged equidistantly are added to strengthen the structure of the flexible cable body during use, avoid breakage caused by rats gnawing, and save costs.
