Portable cable connecting device

Technical Field

The utility model relates to a portable cable junction device.

Background

In the power production work, two or more cables are often required to be connected so as to realize the functions of temporary transmission of electric energy, input and setting of test signals, measurement and sampling of voltage and current and the like. The power production worker usually strips the outer insulating skin of the end of the cable to be connected, then fixes the cable by winding, binding and the like, and finally wraps the cable with an insulating tape in an insulating way (sometimes, the cable also plays a role in fixing) to realize the connection of the cable.

The conventional cable connection method has the following disadvantages:

1. the cable connection needs to be fixed in a winding mode, a binding mode and the like, sometimes, the fixing work is not easy to complete due to factors such as cable materials or shapes, long time is needed, and the efficiency is low.

2. The cables may lose effective connection due to poor fixing process of winding and binding, cable pulling during work and the like, and the connection work needs to be carried out again.

3. Problems of poor insulation wrapping process, damage of the insulation tape and the like may cause related work to be incomplete, and personal safety of workers may be damaged.
