FIG. 1 shows a wall structure 10 in which two substantially identical panels 11 and 12 are connected to each other. Of course, the respective panels 11 and 12 may have different lengths from each other.

Each of the panels 11 and 12 has a rigid rectangular frame inside. The frames are then connected to each other by lateral rails. These rails are channel-shaped and therefore have a hollow structure in the frame, for example a honeycomb structure. And a thin sheet is covered on both sides of the frame. That is, something like a woven sheet is coated, which constitutes the surface of the panel.

A wiring pipe 13 is attached to the lower edge of each of the panels 11 and 12. That is, the conduit 13 has power equipment 14 and 15, which are located in the corners of the lower edges of the panels 11, 12. In addition, the multi-core cable 16 or an individually separated cable is connected between the electric power devices 14 and 15. Any one of the multi-core cable 16 or the individually separated cables is configured as a ground wire 33, and these conductors are arranged in a closed conduit 13 when connecting between the power devices 14 and 15. To be done. The wiring pipe 13 connects the housings of the electric power devices 14 and 15. The conduit 13 is usually fixedly attached to the bottom rails of the frame forming the panels 11, 12 by locking means 18, but it can also be attached and detached. In addition, an engaging arm 29 for attaching the wiring pipe 13 to the bottom wall of each of the panels 11 and 12 is provided in the wiring pipe 13.

The closed conduit 13 has a channel 19 provided with a groove 25 having a lower opening and flanges 23, 24 on both sides along the longitudinal direction, and a detachable cover 20 for covering the opening side of the groove 25. The multi-conductor cable 16 or the individually separated cables, or the ground wire 33 is accommodated in the conduit 13 as described above. In particular, the channel 19 is composed of a bottom wall 22 and side walls 22a and 22b forming a groove 25, and left and right flanges 23 and 24. The cover 20 is attached to the lower portions of the flanges 23 and 24 to engage the engaging edge 26. Are engaged with the edges of the flanges 23 and 24 to cover the opening side of the groove 25. Inside the bottom wall 22 of the channel 19, a wire crimp portion 21 is formed, and in addition, a large number of pilot holes 28, engagement arms 29, and spacers 27 are formed. As best shown in FIG. 6, the wire crimping portion 21 is formed by a pair of crimping pieces 30 cut and raised from the bottom wall 22 of the channel 19 and arranged at a predetermined interval.

As an example of a device for processing the wiring pipe 13, the power equipment 14, 15, the spacer 27, the multi-core cable 16, and the channel 19 having the ground wire 33 are fixed as shown in FIG. It is placed on the table 40. A crimping press 35 is attached to the fixed base 40. The fixed table 40 has a slide type channel table 31, a set groove 36 is formed in the center of the slide type channel table 31, and the channel 19 is set therein. Further, a pair of shafts 38 and 39 are provided at intervals on the slide type channel table 31, and are configured to advance and retreat toward the crimping press 35 along the pair of shafts 38 and 39 while being guided thereby. . Further, a wire guide 34, which is arranged at a predetermined distance from the set groove 36, is held upright on the slide type channel stand 31 on the fixed stand 40 so as to hold the multicore cable 16 away from the channel 19. (See FIGS. 3 and 4).

As shown in FIGS. 3 and 4, the channel 19 and the ground wire 33 are located between the wire guide 34 and the set groove 36. Then, the multi-core cable 16 other than the ground wire 33 is positioned at a position opposite to the position where the set groove 36 exists with the wire guide 34 inside. When the channel 19 and the power devices 14 and 15 are rotated about 90 degrees about the longitudinal axis of the channel 19, the channel 19 is positioned in the set groove 36 on the slide type channel stand 31. At this time, as shown in FIG. 4, the multi-core cable 16 is separated from the ground wire 33 by the wire guide 34.

Referring again to FIGS. 3 and 4, the vertical and horizontal position setting of the channel 19 is extremely important for crimping the crimping piece 30 of the wire crimping portion 21 to the ground wire 33.
