As shown in detail in FIG. 3 to FIG. 5, the jumper wire drawing device 20 accommodates a piece member (moving member) 30 in a rectangular cross section rectangular guide (guide member) 21 so as to be movable in the longitudinal direction. In addition, a drive mechanism 40 for driving the piece member 30 is provided. The square pipe 21 extends over substantially the entire length of the partition frame 11, and the back surface is fixed to the partition frame 11. The square pipe 21 has plugs 22L and 22R fixed to the openings at both ends with screws or the like, and a sliding groove 21a extending in the longitudinal direction is formed on the front surface. As will be described later, the locking piece 32 of the piece member 30 slidably projects from the sliding groove 21a.

The piece member 30 is configured by fixing a locking piece 32 to a main body 31 movably accommodated in the square pipe 21, and the locking piece 32 projects outside from the sliding groove 21a. The main body 31 has ends of a wire 43, which will be described later, fixed to both ends in the longitudinal direction of the square pipe 21, and the wire 43 travels to move inside the square pipe 21. The locking piece 32 is slidably fitted in the sliding groove 21a, and a notch 32a capable of locking the end of the jumper wire 14 is formed at the end protruding outward.

The drive mechanism 40 is provided with the wire 43 whose both ends are locked to the main body 31 of the piece member 30 described above in the vicinity of the spools 41L and 41R and the spool 41L provided on both inner sides of the square pipe 21. It is configured by being endlessly wound around the drive spool 42. The spool 41L is rotatably attached to the left inside of the square pipe 21 in FIG.

The spring 47 biases the rod 45 in the direction in which the support shaft 46 approaches the plug 22R, that is, the spool 22R to the right in FIG. 5, and adjusts the tension of the wire 43 wound around the spool 41R.

The drive spool 42 is supported by a bracket 50 at the end of the square pipe 21. The drive spool 42 is fixed to a rotary shaft 51 rotatably supported by a bracket 50, and a wire 43 drawn out from the inside of the square pipe 21 is wound a plurality of times. One end of the rotary shaft 51 projects to the front of the bracket 50, and a fitting portion 51a having a rectangular cross section that can fit with the handle 52 (see FIG. 1) is formed at this end portion. The drive spool 42 is rotated integrally with the rotary shaft 51 by an operator rotating the rotary shaft 51 with the handle 52, and the wound wire 43 is run to move the piece member 30.

In this embodiment, the jumper work is performed as follows. That is, first, in the outer wire terminal wiring portion H, one worker puts the jumper wire 14 wound and held on a reel or the like in the vicinity of the designated terminal 13 to be connected, and pulls out the jumper wire 14 from this reel to set the end portion. The piece 32 is engaged with the notch 32a of the engaging piece 32. Next, the operator operates the handle 52 to move the piece member 30 to the jumper ring 11a closest to the station-side terminal 12 to be connected. After this, this worker removes the end of the jumper wire 14 from the bridge member 30 and transfers it to the worker who is on standby in the in-station terminal wiring part V through the jumper ring 11a. Then, the operator of this in-station terminal wiring section V connects the jumper wire 14 to the station side terminal 12, and the operator of the outside wire terminal wiring section H cuts the jumper wire 14 from the reel to the designated terminal 13. Connecting.

As described above, in this embodiment, the end of the jumper wire 14 to be connected to the terminal 12 on the station side is moved by the movement of the piece member 30 by the operation of the handle 52, so that the jumper work is performed by two persons. It can be done by the operator, and the operator does not have to stretch the jumper wire 14. Therefore, the burden on the worker is reduced, and the jumper work can be performed safely and efficiently.

In the above-described embodiment, the piece member 30 is moved by operating the handle 52, but an engaging portion 51b (see FIG. 5) for engaging with an electric tool such as a cross hole is formed in the fitting portion 51a. It is also possible to drive the drive reel 42 by an electric tool capable of rotating in the forward and reverse directions to move the piece member 30 and move the end of the jumper wire 14. Further, by adopting a mode in which the power tool can be used for movement in this way, the burden on the operator can be further reduced.

FIG. 6 shows another embodiment of the present invention. In this embodiment, the pulse motor 70 is drivably connected to the drive spool 42 in the above-described embodiment, and the pulse motor 70 is controlled by the controller 91 to move the piece member 30. In this embodiment, the same parts as those in the above-mentioned embodiment are designated by the same reference numerals, and the description and illustration thereof will be omitted.

The controller 91 has a wireless operation device 90, a moving distance conversion circuit 81, a motor control circuit 80, a motor drive circuit 72, and a power supply 75. The motor drive circuit 72 is connected to the pulse motor 70. There is. The operating device 90 is provided with a numeric keypad for position designation, etc. The operator operates this key to input the current position of the piece member 30 and the target position to be moved. Output to the moving distance detection circuit 81.

Note that, as an example of the designation of the position by the key, since the vertical frame members 11v of the partition frame 11 are arranged at equal intervals and the jumper rings 11a are arranged at equal intervals, these vertical frame members 11v, etc. It is done by keying this number with the number etc. according to the distance.

The moving distance conversion circuit 81 calculates the moving distance and the moving direction of the piece member 30 based on the output of the operation device 90. That is, the moving distance conversion circuit 81 calculates a−b (= c) when the current position of the piece member 30 is a and the target position is b, and calculates the moving distance from the absolute value of c as c of The direction of movement is determined from positive and negative, and signals representing these are output to the motor control circuit 80.

The motor control circuit 80 outputs to the motor drive circuit 72 a gate control signal according to the moving distance based on the output of the moving distance converting circuit 81 and a polarity control signal according to the moving direction. The motor drive circuit 72 outputs a signal of the number of pulses corresponding to the gate control signal input from the motor control circuit 80 to the pulse motor 70 with the polarity according to the polarity control signal.

In this embodiment, the operator carries the operation device 90 and inputs the current position of the piece member 30 and the target position to be moved, whereby the piece member 30 moves to the target position. Therefore, when the jumper wire 14 is extended from the designated terminal, the position closest to the designated terminal is designated as the target position to move the piece member 30, and the end portion of the jumper wire 14 is locked to the piece member 30. Then, after that, the piece member 30 is moved by designating the position of the jumper ring 11a closest to the station side terminal 12 to which the current position and the end of the jumper wire 14 are connected to the operation unit 90 as the target position. .

Therefore, the worker removes the end of the jumper wire 14 from the piece member 30 stopped at the designated position and delivers it from the jumper ring 11a to the worker who is on standby in the in-station terminal wiring section V, and this worker connects the station side terminal. The jumper work can be done more easily by connecting to.

In the embodiment described above, the piece member 30 supports an arm that is driven by an actuator to move up and down or swings, and a locking portion that can lock the end of the jumper wire 14 is provided at the tip of the arm. It is also possible to drive the arm when the piece member 30 reaches the target position so that the end of the jumper wire 14 is desired by the jumper ring 11a. With this configuration, it is possible to perform jumper work on two workers, that is, the worker of the internal terminal wiring part V and the worker of the external terminal wiring part H, and the jumper work can be performed more efficiently. You can do it.
