[0030] Please refer to Figures 1-5 The above technical solutions will be described in detail by the following embodiments of the present application.

[0031] A cable with an embedded insulation coating, comprising:

[0032] A core 1, the core 1 comprises a loose tube 13, and the loose tube 13 is externally provided with a first embedded groove 14.

[0033] The loose tube 13 is integrally formed by using PBT material, and the PBT material has insulation and good mechanical strength.

[0034] A plurality of conductor copper wires 11 are placed in the loose tube 13, and a conductor copper wire filling paste 12 is filled between the conductor copper wires 11 and the loose tube 13.

[0035] The conductor copper wire filling paste 12 is used to prevent external moisture from penetrating in, and water will affect the strength of the conductor copper wires 11. The conductor copper wires 11 should be placed loosely in the loose tube 13, and the loose tube 13 can prevent the internal conductor copper wires 11 from being extruded.

[0036] Further comprising:

[0037] A reinforcing member 2, the reinforcing member 2 comprises a reinforcing core 21, and the reinforcing core 21 is in contact with the loose tube 13 through a reinforcing core insulation sleeve 22. The reinforcing core 21 is made of twisted metal wires, and the reinforcing core insulation sleeve 22 is wrapped outside the reinforcing core 21.

[0038] The reinforcing core 21 is used to improve the tensile strength of the cable. The reinforcing core insulation sleeve 22 is made of the same material as the loose tube 13.

[0039] The reinforcing core insulation sleeve 22 is externally provided with a first embedded protrusion 23 which cooperates with the first embedded groove 14.

[0040] The first embedded protrusion 23 cooperates with the first embedded groove 14 to prevent the reinforcing core insulation sleeve 22 and the loose sleeve 13 from sliding and twisting.

[0041] The insulation layer 3 comprises an inner insulation sleeve 31 which is in contact with the loose sleeve 13. The inner insulation sleeve 31 is internally provided with an inner embedded protrusion 33 which cooperates with the first embedded groove 14.

[0042] The inner insulation sleeve 31 is made of rubber material and is extruded. The inner embedded protrusion 33 cooperates with the first embedded groove 14, and the first embedded protrusion 23 cooperates with the first embedded groove 14 to prevent the loose sleeve 13 and the inner insulation sleeve 31 from twisting.

[0043] The inner insulation sleeve 31 is internally filled with a cable filling paste 32 between the reinforcing core insulation sleeve 22 and the loose sleeve 13.

[0044] The cable filling paste 32 is used to prevent external moisture from entering and to improve the service life of the cable.

[0045] The inner insulation sleeve 31 is externally provided with a cable groove 34 in which a cable 35 is placed. The outer insulation sleeve 36 is internally provided with a cooperating groove 37 which cooperates with the cable 35.

[0046] The outer insulation sleeve 36 is made of rubber material and is extruded. The cooperating groove 37 cooperates with the cable 35 which is placed in the cable groove 34, and the three cooperate to prevent the outer insulation sleeve 36 and the inner insulation sleeve 31 from twisting.

[0047] The first embedded protrusion 23 cooperates with the first embedded groove 14 to prevent the reinforcing core insulation sleeve 22 and the loose sleeve 13 from sliding and twisting. The inner embedded protrusion 33 cooperates with the first embedded groove 14 to prevent the loose sleeve 13 and the inner insulation sleeve 31 from twisting. The cooperating groove 37, the cable 35 and the cable groove 34 cooperate to prevent the outer insulation sleeve 36 and the inner insulation sleeve 31 from twisting. Therefore, it is difficult for the loose sleeve 13, the reinforcing core insulation sleeve 22, the inner insulation sleeve 31 and the outer insulation sleeve 36 to twist, which reduces the internal twisting during cable laying and improves the optical signal loss rate of the conductor copper wire 11.
