Problems solved by technology

[0002] The current cables generally include a cable sheath and a cable core wire. The cable core wire is arranged in the cable sheath, but the current cable sheath is generally made of ordinary flexible materials, which are very easy to be ignited. Due to the long-term aging of the cable, it is easy to spontaneously ignite, causing a fire inside the entire cable shaft, and a fire in the entire building, causing serious economic losses
In addition, the current cable has poor heat dissipation performance, which affects the normal use of the cable and reduces the service life of the cable

Embodiment Construction

[0018] Such as figure 1 and figure 2 As shown, the composite fireproof cable includes the cable outer protective layer 2, and the cable outer protective layer 2 has a cable installation cavity 13, and the cable main body is installed in the cable installation cavity 13;

[0019] The main body of the cable includes a cable outer layer 11 and a cable core wire 12. An interface 4 is respectively installed at both ends of the cable outer protective layer 2. The cable core wire 12 protrudes outside through the interface 4. The cable core wire 12 and the interface 4 The contact end is fixed with glue;

[0020] The two sides of the cable outer layer 11 are respectively symmetrically provided with more than one heat dissipation pin 1, and one end of the heat dissipation pin 1 extends into the arc-shaped groove 7 provided on the cable outer protective layer 2, and the bottom surface of one side of the arc-shaped groove 7 A sealing part 3 is fixedly installed. The inside of the seali...

Abstract

The invention discloses a composite fireproof cable. The composite fireproof cable comprises a cable outer protection layer; the cable outer protection layer is internally provided with a cable installation cavity; a cable main body is installed in the cable installation cavity; the cable main body comprises a cable outer cover layer and a cable core; the interface ends at two ends of the cable outer protection layer are installed with interfaces; the cable core passes through the interfaces and reaches out of the outer part; and the contact end between the cable core and the interface is fixed by a glue. The cable disclosed in the invention has excellent cooling performance; and in the case of cable outgoing spontaneous combustion, the contact friction force is used to extinguish the flame, and at the same time, a flame retardant liquid is extruded to prevent further combustion.

Description

technical field [0001] The invention relates to a cable, in particular to a composite fireproof cable. Background technique [0002] The current cables generally include a cable sheath and a cable core wire. The cable core wire is arranged in the cable sheath, but the current cable sheath is generally made of ordinary flexible materials, which are very easy to be ignited. Due to the long-term aging of the cable, it is easy to spontaneously ignite, causing a fire inside the entire cable shaft, and a fire in the entire building, causing serious economic losses. In addition, the current cable has poor heat dissipation performance, which affects the normal use of the cable and reduces the service life of the cable. Contents of the invention [0003] The technical problem to be solved by the present invention is a composite fireproof cable, which can ensure heat dissipation and have better flame retardancy, greatly improving the safety of the cable in use. [0004] The presen...
