Wire or cable waterproof fast-installed connector

Abstract

The invention relates to a wire or cable waterproof fast-installed connector comprising one housing, two end cover, two sealing rings, and a wire or cable connectors. The housing is a hollow tubular structure. Annular teeth are symmetrically disposed on both ends of the housing. The outer surfaces of the annular teeth are provided with arc surfaces or conical surfaces. External thread connecting surfaces are arranged between the annular teeth and the main body of the housing. The inner surfaces of the end covers are correspondingly provided with matched inner thread connecting surfaces, arc surfaces, or conical surfaces. The wire or cable connectors are disposed in the housing. The two sealing rings are embedded in the annular teeth. The two end covers are connected with the external thread connecting surfaces on both sides of the housing respectively. Thus, the wire or cable connectors form a sealing waterproof structure. The wire or cable waterproof fast-installed connector is good in sealing and waterproof performance, convenient and fast to install and uninstall, overcomes defects of complex structure and complicated operation of a conventional cable connector, and is improved in waterproof sealing performance and damage and tensile failure resistance, suitable for cables in various specifications, large in application range, and high in reliability.

Description

technical field [0001] The invention relates to an electric wire or cable joint connection device, in particular to a waterproof quick-fit connector for electric wires or cables. Background technique [0002] Existing wires include single-strand wires and multi-strand wires, and cables include single-core cables and multi-core cables. Both electric power and communication engineering need to use wires or cables to transmit electric energy or communication signals. During engineering construction, it is often necessary to connect two wires or cables to each other, or to disconnect two connected wires or cables. At present, the connection methods of wires or cables usually include welding connection and plug-in connection using male and female plugs. A pair of wires or cables are connected to form one or more independent joints, and then insulating tape is wrapped on the joints or heat shrinkable The casing is sealed and insulated. However, the heat source must be carried wh...

AI Technical Summary

Problems solved by technology

However, the heat source must be carried when installing and connecting the heat shrinkable sleeve, the construction is inconvenient, and the connection operation is more complicated

[0003] The sealing and insulating methods of insulating tape or heat-shrinkable sleeves are used above, not only the operation time is longer, the construction and installation efficiency is low, but also the sealing and waterproof performance of the cable joint is not ideal, and it cannot be reused repeatedly.

When the wire or cable is damaged by a large external force, the cable joint is easily damaged or disconnected. Once the joint is disconnected, the sleeve must be destroyed and re-socketed. The normal transmission of power and communication signals will be greatly affected. not tall

On the other hand, when important power or communication cables are repaired, the time requirement is relatively high, and even if a short time is saved, a large economic loss can be recovered
