Description

Technical Field

[0001] This utility model belongs to the field of cable termination technology, specifically relating to a prefabricated plug-in termination device for tunnel emergency telephone cables. Background Technology

[0002] Termination cables, also known as modular cables or connector cables, are splicing cables used in data communication networks. Both ends are typically connected to adapters or connectors for plugging and unplugging. The splicing method varies depending on the cable specifications and mainly includes core wire butt welding, insulation protection, inner and outer sheathing, and gas-tight protection. This requires the use of solder, core wire sleeves, heat-shrinkable sheaths, junction boxes, and various clamps and testing tools. Termination work necessitates replacing the cable section with one suitable for environmental requirements to ensure that the line performance meets standards.

[0003] The installation of emergency telephones and the laying of emergency cables in tunnels are constrained by the handover of civil engineering work areas, and the construction period is uncertain. In addition, there are many emergency telephones to be installed in long tunnels, and the amount of work involved in the termination and splicing of emergency cables is large.

[0004] Existing cable termination and splicing methods still have some shortcomings. Most of them are spliced ​​by workers on the construction site, which is inefficient and cannot meet the construction requirements. Therefore, we propose a prefabricated plug-in termination and splicing device for tunnel emergency telephone cables. Utility Model Content
