Description

  The present invention relates to a cable winding device used for winding / drawing cables of various electric / electronic devices such as a power cable and a communication cable.

  In the prior art 1, in use, the cable is wound in consideration of the convenience of use from either one of the drawing terminals on one side of the cable wound around the five regular pentagonal multi-stage winding pulleys or the other drawing terminal. There is known a cable winding device that is pulled out from a collecting case.

  With the cable pulling output, each of the five multi-stage take-up pulleys is moved by a centripetal force drawn toward the center, and the pulleys work so as to extend the respective suspension springs so that the pentagon is gradually reduced. In that way the cable is drawn out as long as necessary.

  When the drawn cable is rewound onto the winding case and the use is finished, when the cable pulling output is released from the drawing position, the suspension spring acts in the direction of reducing the spring length by its elastic force. That is, the pulley bearing stay is expanded and moved in the centrifugal direction by the spring force due to the reduction of the suspension spring, and the multi-stage take-up pulley rotates accordingly, and the cable is gradually rewound (for example, see Patent Document 1). .

  As prior art 2, in use, a cable is wound around an equilateral polygon so as to circumscribe five star-shaped multi-stage winding pulleys and a multi-stage fixed shaft pulley. There is known a cable winding device that is drawn out from a winding case in consideration of the convenience of use from any of the drawing terminals.

  By pulling the cable, the five multi-stage take-up pulleys are attracted toward the center that reduces the cable circumscribed shape while extending the suspension spring and move all at once. In that way the cable is drawn out as long as necessary.

  On the other hand, when the cable in the pulled out state is rewound into the winding case again and the use is finished, when the tensile force applied to the cable is released from the drawing position, the suspension spring is reduced to the original length. In other words, the multistage variable pulleys are pulled outward in the radial direction via the variable bearing stays by the compressive force when the suspension springs are contracted, and spread in a radial pattern. Such a spreading operation of the multi-stage variable pulley gradually increases the cable circumscribing and rewinds the cable (see, for example, Patent Document 2).

  As the prior art 3, the wire harness accommodated in the spool protector is a wire that is connected to the back door side when the back door is opened, and is drawn out from the wire lead-out portion, and detours inside the spool protector. It is known that the harness detour distance is shortened, the movable member moves to the wire drawing part and the wire drawing part side by pulling the wire harness, and the wire protector discloses a spool protector that follows the opening operation of the back door. Yes.

  Conversely, when the back door is closed, the pulling force on the wire harness toward the back door disappears, and the movable member is pulled back to the original position by the restoring force of the annular rubber spring, which increases the detour distance of the wire harness. The excess portion pulled out of the wire harness is wound back and absorbed from the wire lead-out portion.

  When this spool protector is used, the wire harness does not hang down in the trunk room and is automatically pulled out and rewound, so that it is possible to prevent the wire harness from being caught on the load etc. and being damaged. At the same time, the appearance is also good (see, for example, Patent Document 3).

  In the prior art 4, after the wire harness is housed in the case where the holder is positioned at the uppermost stage of the saw-shaped uneven portion, one or more electric wires having a surplus length are pulled through the notch to the stopper. A wire rod holding protector is disclosed which hangs and then moves the stopper downward along the serrated irregularities according to the length of the electric wire.

  For this reason, the electric wire is held by the holder in a meandering state, and the slack of the electric wire is absorbed (see, for example, Patent Document 4).

  However, although the configuration of Patent Documents 1 to 4 is a drum type, when the cable is wound, one end on the winding side is rotated and twisted, and the cable (electric wire) is easily disconnected.

  Further, in order to prevent this, a complicated contact mechanism is required, which may cause contact failure. Furthermore, there is a problem that the cable (electric wire) is disconnected due to the irregular winding.

  Therefore, in the method of folding a cable (electric wire) having a plurality of winding points, one end on the winding side rotates and twists when the cable is wound, and a complicated contact mechanism is used to prevent the cable (electric wire) from being disconnected. There is a problem that it becomes necessary and causes poor contact. Furthermore, the cable (electric wire) was disconnected due to random winding.

  Therefore, the subject of this invention is providing the cable winding apparatus which can reduce the disconnection of the cable by rotation twist or disorder | damage | failure winding.

And between the first and second support plate portions so as to be biased And a plurality of winding springs digits, each of the winding spring cable winding device can be obtained with a different spring force.

  According to the cable winding device of the present invention, the following effects can be obtained.

  The first effect is that the cable can be stably wound because the spring force of the winding spring is changed from weak to strong.

  As a second effect, the winding method is foldable, and the shaft moves and rotates at a plurality of locations, so that the pulling load on the cable can be dispersed and disconnection can be prevented.

  Therefore, when winding the cable automatically, winding the cable flexibly can reduce the disconnection of the cable due to rotational twisting or turbulent winding.
