Abstract

Provided is a flat cable winding device and an assembling method thereof, which can prevent slack of a flat cable and achieve smooth winding and leading out of the flat cable. A flat cable winding device includes a rotating table, a plurality of rollers, and a central shaft rotatably and pivotally supporting the rotating table. The central shaft includes an auxiliary wound portion in which the flat cable is wound for at least one turn. An inner wound portion is formed along an outer circumference of the auxiliary wound portion, and an outer wound portion is formed along outer circumferences of the plurality of rollers, thereby preventing the slack at the inner wound portion when leading out the flat cable.

First claim

The invention claimed is:

1. A flat cable winding device for winding one end side of a flat cable and leading out another end side of the flat cable, the flat cable winding device comprising:
a case having an insertion hole through which the flat cable is inserted;
a central shaft provided in the case and retaining the one end side of the flat cable;
a rotating body configured to rotate about the central shaft; and
a biasing element configured to bias the rotating body in a winding direction of the flat cable,
wherein the rotating body includes a reversing roller configured to reverse the flat cable entered from the insertion hole of the case toward the central shaft, and a plurality of guide rollers arranged in a circumferential direction of the rotating body,
wherein, when the rotating body which is biased by the biasing element is rotated in the winding direction, the flat cable is wound up so as to form an inner winding portion formed by the flat cable wound around the central shaft and an outer winding portion formed by the flat cable wound around outer circumferences of the reversing roller and the plurality of guide rollers, and
wherein, in a state in which any portion of the flat cable is not in contact with the plurality of guide rollers, the central shaft is provided with an auxiliary wound portion in which the flat cable is wound for at least one turn about the central shaft.

2. The flat cable winding device according to claim 1 , wherein the auxiliary wound portion is formed by winding the flat cable around the central shaft for three or more turns.

3. A flat cable winding device for winding one end side of a flat cable and leading out another end side of the flat cable, the flat cable winding device comprising:
a case having an insertion hole through which the flat cable is inserted;
a central shaft provided in the case and retaining the one end side of the flat cable;
a rotating body configured to rotate about the central shaft; and
a biasing element configured to bias the rotating body in a winding direction of the flat cable,
wherein the rotating body includes a reversing roller configured to reverse the flat cable entered from the insertion hole of the case toward the central shaft, and a plurality of guide rollers arranged in a circumferential direction of the rotating body,
wherein, when the rotating body which is biased by the biasing element is rotated in the winding direction, the flat cable is wound up so as to form an inner winding portion formed by the flat cable wound around the central shaft and an outer winding portion formed by the flat cable wound around outer circumferences of the reversing roller and the plurality of guide rollers, and
wherein, in a state in which any portion of the flat cable is not in contact with the plurality of guide rollers, the central shaft is provided with an auxiliary wound portion in which the flat cable is wound for at least half turn about the central shaft.

4. A method for assembling the flat cable winding device according to claim 1 , comprising the steps of:
after one end side of the flat cable is retained at the central shaft, forming the auxiliary wound portion by winding the flat cable around the central shaft for at least half turn; and
leading out the another end side of the flat cable, which is extended across from the auxiliary wound portion to the reversing roller and reversed, from the insertion hole to outside of the case.

5. A method for assembling the flat cable winding device according to claim 2 , comprising the steps of:
after one end side of the flat cable is retained at the central shaft, forming the auxiliary wound portion by winding the flat cable around the central shaft for at least half turn; and
leading out the another end side of the flat cable, which is extended across from the auxiliary wound portion to the reversing roller and reversed, from the insertion hole to outside of the case.

6. A method for assembling the flat cable winding device according to claim 3 , comprising the steps of:
after one end side of the flat cable is retained at the central shaft, forming the auxiliary wound portion by winding the flat cable around the central shaft for at least half turn; and
leading out the another end side of the flat cable, which is extended across from the auxiliary wound portion to the reversing roller and reversed, from the insertion hole to outside of the case.
