FIG. 6 shows a perspective view of a conventional cable termination. In the figure, a cable head 1 is provided with a T-branch connection portion 3 at its base, and cables 4 are connected to each other inside this. Such a cable end is supported and fixed by the frame 2. That is, the cable head 1 is fixed to the upper surface of the frame 2. On the other hand, the cable 4 is gripped by the grip fitting 5 and fixed to the mounting fitting 6 which is hung on the frame 2.

A side view of the grip 5 and the mounting 6 is shown in the lower left portion of the figure. As shown in the figure, the holding metal fitting 5 is composed of an upper metal fitting 51 and a lower metal fitting 52 which are respectively bent to sandwich the cable 4. The upper metal fitting 51 and the lower metal fitting 52 are fastened to each other by a bolt 53 to be integrated with each other, and hold the cable 4. The lower metal fitting 52 is fixed to the upper surface of the mounting metal fitting 6 by bolts 54. The cable 4 is fixed to the frame 2 in such a state so that external stress applied to the cable 4 is not directly applied to the T-branch connection portion 3.

FIG. 7 shows a perspective view of another conventional cable termination. In this example, as in the example of FIG. 6, the cable head 1 is supported and fixed on the frame 2, and the end of the cable 4 terminates inside the cable head 1. The cable 4 is curved from a horizontal portion, rises vertically, and is terminated inside the cable head 1. Therefore, in order to hold the cable 4, the holding metal fitting 5 and the mounting metal fitting 7 for fixing this are provided. Both ends of the mounting bracket 7 are fixed to predetermined portions of the frame 2. Also in the example as shown in FIG. 7, the holding metal fitting 5 prevents the force due to the weight of the cable 4 or the expansion and contraction of the cable 4 from being transmitted to the inside of the cable head 1.

This fixed position needs to be selected as an optimum position so as not to apply an excessive force to the cable 4. However, the T-branch connection 3 and the components of the cable head 1 and the cable 4 are each manufactured in a factory and the frame 2 is assembled in the field where the cable terminations should be installed beforehand. Therefore, if you do not assemble the frame 2 and the mounting brackets 6 and 7 after making sufficient contact in advance and accurately grasping the size of the parts and cables, etc. In some cases, it may not be possible to attach it to the.

In order to avoid such a situation, the mounting bracket 6 may be fixed to the frame 2 while actually measuring the dimensions at the final assembly of the cable end. However, this makes the on-site work relatively complicated and makes it impossible to carry out efficient construction in a short time. In addition, when vibration due to an earthquake or various factors is applied to the frame 2, the T-branch connecting part 3 and the gripping metal 5 vibrate independently, and an abnormal force is applied to the T-branch connecting part 3 via the cable 4. In some cases, they will join. The present invention has been made in view of the above points, and provides a cable supporting portion capable of supporting a cable easily, easily, and surely and protecting a cable connecting portion and a terminal portion. The purpose is.
