Patent attributes
A retractable cable device having protecting function mainly comprises a housing, a spiral spring, a spool disk, an arresting system, and a communication cable. The spool disk pivoted on a shaft within the housing is wound by the communication cable. The spiral spring provides the spool disk with a reeling force to reel in the communication cable. The rotation of the spool disk flexibly controlled by the arresting system decides the protruding length of the communication cable. A swaying member installed on the spool disk is utilized to replace the conventional immovable clip for fixing the communication cable. Whereby, when the entire communication cable is drawn out, the communication cable at a second end of the swaying member presents a larger bent angle. Therefore, the communication cable is subjected to bending with less sharp degree, thence protecting the communication cable, especially for the core, by preventing it from damage.
