Description

Technical Field

[0001] The utility model relates to the technical field of communication cable cutting, and more specifically to a fixed-length cutting device for communication cables. Background Art

[0002] Communication cables are cables for transmitting telephone, telegram, fax documents, television and radio programs, data and other electrical signals. They are composed of one or more pairs of mutually insulated conductors twisted together. Compared with overhead wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less influence by natural conditions and external interference.

[0003] When using communication cables, they need to be cut to a fixed length. By detecting the moving distance of the cable and converting it into an electrical signal, the length of the cable that has been fed can be accurately measured. When the preset cutting length is reached, the photoelectric sensor will send a signal to the control system to trigger the cutting action.

[0004] Based on the above, the inventors have discovered that: currently, when cutting communication cables to a fixed length, there is a lack of limiting structure around the cables, which causes the cables to easily shift when cut, thereby reducing the cutting quality of the communication cables. Therefore, in view of this, the inventors have studied and improved the existing structure, and provided a fixed-length cutting device for communication cables, in order to achieve a more practical purpose.
