Abstract
A fire-resistant and waterproof multi-core cable and its connector device belong to the technical field of special cables and solve the problems of easy damage to existing cable connectors, poor fire-resistant, waterproof and high-temperature-resistant capabilities, and poor sealing capabilities at cable connectors. The invention includes cables, joints A, joints B, O-shaped sealing rings, screws and nuts, memory alloy arc pieces and flame retardant components on the cables to enable the cables to have automatic fire prevention capabilities, and the heat dissipation mechanism also enables the cables to have automatic heat dissipation functions. The structure of the terminal post and the terminal block are complementary to ensure that the cables on both sides are connected reliably. In the environment of alternating cold and heat, it can also ensure that the cable has good sealing performance, and greatly enhances the impact resistance of the cable. The O-ring, the sealing sleeve on the joint A, and the sealing sleeve on the joint B can ensure The entire structure is sealed.
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...
