Abstract: A micro-type communication wire winder includes a housing, a rotary disk, a buckling piece, a communication wire and a spiral spring. The rotary disk is pivotally installed in the receiving groove of the housing and one surface thereof is installed with an axle bush and an outer circular cover with slots for fixing and winding a communication wire. While another surface is installed with a ring protrusion for receiving and engaging a spiral spring or receiving the spiral spring in a cavity adjacent to the rotary disk so that the spiral spring can be wound around the ring protrusion. Thus, the communication wire has a rewinding force applied thereon. The rim of the rotary disk is further installed with a tilt buckling groove. A buckling piece at the side of the housing obliquely resists against the rim of the rotary disk.

Abstract: A reversible cable reel which includes two cover shells having a respective center shaft axially connected to each other, two cable wheels respectively mounted around the center shafts inside the cover shells, two spiral springs respectively mounted around the center shafts inside the cover shells, each spiral spring having an inner end connected to the respective cover shell and an outer end connected to the respective cable wheel, two cables respectively wound round the cable wheels, each cable having a fixed end fastened to the respective cable wheel and a free end extended out of the respective cover shell and mounted with a module plug, a first terminal unit mounted in one cable wheel and connected to conductors in one cable, a second terminal unit mounted in the other cable wheel and connected to conductors in the other cable and separated from the first terminal unit by a cover plate, the second terminal unit having contact means projecting into respective through holes on the cover plate into contact
