Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a cable connection device. Background Art

[0002] Cable emergency splicing is an important part of power construction. It has high quality requirements: the splicing must be fast and reliable and maintain proper performance for a long time to ensure smooth transmission; the construction must be highly efficient, with low labor intensity and easy operation.

[0003] During the existing cable splicing process, it is difficult for the center lines of the two cables to remain in the same straight line.

Therefore, we have introduced a new cable splicing device. Utility Model Content
