Multi-core cable with fireproof and waterproof functions and joint device thereof

Abstract

The invention discloses a multi-core cable with fireproof and waterproof functions and a joint device thereof, belongs to the technical field of special cables, and solves problems that an existing cable joint is easy to damage, poor in fireproof, waterproof and high-temperature-resistant capabilities and poor in sealing capability of a cable joint part. The multi-core cable comprises a cable, a joint A, a joint B, an O-shaped sealing ring, a screw and a nut, a memory alloy arc-shaped sheet and a flame retardant component on the cable enable the cable to have an automatic fireproof capability,a heat dissipation mechanism further enables the cable to have an automatic heat dissipation function, and a binding post and a wire holder are complementary in structure so that reliable connectionof the cables on two sides is guaranteed; and a periphery of the binding post and the periphery of the wire holder are evenly filled with an epoxy resin pouring sealant at intervals, the binding postand the wire holder are insulated and isolated from each other, the cable can be ensured to have good sealing performance even in the cold and hot alternating environment, the impact resistance of thecable is greatly improved, and the O-shaped sealing ring, the sealing sleeve on the joint A and the sealing sleeve on the joint B can ensure the sealing of the whole structure.

Description

technical field [0001] The invention belongs to the technical field of special cables, and in particular relates to a fire-resistant and waterproof multi-core cable and a joint device thereof. Background technique [0002] In the process of power transmission, the cable is the most common carrier. In the actual use of the cable, because the cable core part of the cable is generally a copper core, it is easy to accumulate heat after long-term power-on. If the heat cannot be dissipated in time, when the heat accumulates to After a certain level, it is easy to cause a fire. And at present, with the continuous acceleration of the urbanization process, there are more and more large-scale public places. Such places consume a lot of electricity and are more likely to cause fires due to cable breakdown. Once a fire occurs in such large-scale public places, the resulting Personal life safety and property loss will be very serious, so higher requirements are put forward for cables, a...
