In FIG. 1 showing a part of an underground multi-circuit switch installed in a hand hole buried underground, 1 is a case which is formed in a sealed state using a stainless steel material. In addition, the inside of this case 1 is equipped with an opening/closing part and an arc-extinguishing gas SF 6
is filled. 2 is bushing, case 1
It is connected to the opening/closing part inside. In FIG. 1, three bushings 2 are arranged in parallel in a direction perpendicular to the paper surface. Next, in the elbow 3 attached to the bushing 2, reference numeral 4 denotes an upright portion, which is constructed in a well-known manner so that it can be attached to and removed from the bushing 2 in its axial direction (vertical direction in FIG. 1). Further, in the mounted state, electrical connection is established as is well known. Reference numeral 5 indicates a horizontal pulling part connected to the rising part 4. 6 is a voltage detection terminal. Next, 7 is a cable whose one end is connected to the horizontal pull-out section 5, and is connected to an underground power distribution line via a hem as shown by the reference numeral 7a. Reference numeral 8 indicates a ground wire attached to the cable 7. Next, reference numeral 10 denotes a fastener, the structure of which is clearly shown in FIGS. 2 to 4. In these figures, 11 is a board, 12 is a stop leg,
Its lower end 12a is hooked on a hook 16 attached to the bushing 2, and its upper end 12b is hooked on the board 1.
It is inserted into a through hole 11a drilled in 1 and hooked on the edge of the hole. 13 is a nut welded and fixed to the base plate 11, and 14 is a tightening threaded rod screwed into the nut 13. By rotating this and pushing it downward, its tip 14a becomes the raised part 4 of the elbow 3.
The elbow 3 is fixed to the bushing 2 by pressing the raised portion 4 downward via a catch 15 attached to the upper end of the bushing. Next, 17 is a support member, in which 18 is a support leg erected from the case 1, 19 is a receiving piece welded and fixed to the upper end of the support leg 18, and as shown in FIG. A plurality of receiving recesses 20, 20, . . . each supporting the horizontal drawing portion 5 are formed.

ボ３の固定状態を確実に維持する。 In the case of the above configuration, when the cable 7 is routed a long way and the cable 7 is pulled in the direction of the arrow 31 in FIG. Therefore, using this as a fulcrum, mark arrow 3 on the rising part 4 of elbow 3.
Forces act in two directions, ie, in the axial direction of the bushing 2, to pull the upright portion 4 out of the bushing 2. However, as is clear from the figure, the force in this direction is
is the force in the direction that exhibits the greatest stopping force. Therefore, the fastener 10 will not be destroyed and will reliably maintain the fixed state of the elbow 3.

れる。 Furthermore, even if a similar force is applied to the cable 7 due to vibration or other causes while the switch is in use, the fixed state of the elbow 3 is maintained as described above, and the elbow 3 is
It is also possible to prevent chatter from occurring at the electrical contact portion between the bushing 2 and the bushing 2, which may cause the contact portion to become rough.

０の破損をも防止し得る効果も生む。 As mentioned above, in this invention, the cable 7
When turning the hem of the bushing 2, the cable 7 is pulled out in a direction transverse to the axial direction of the bushing 2.
A support member 17 is disposed at a lateral position, and this support member 17 supports the horizontal pulling portion 5 of the elbow 3. Therefore, the direction of the force applied to the raised portion 4 and the bushing 2 is controlled by the direction of the force applied to the raised portion 4 and the bushing 2. It is possible to prevent a prying force from being applied to them instead of a force in the axial direction, which has the effect of preventing damage to the elbow 3 and bushing 2. Furthermore, being able to change the direction of the force as described above also prevents prying force from being applied to the fastener 10.
It also has the effect of preventing damage to zero.

る。 Moreover, as mentioned above, prevention of damage to elbow 3 is also possible.
Even if it is possible to prevent damage to the bushing 2 and also to prevent damage to the fastener 10, the support member 17 is selectively arranged at a lateral position of the bushing 2. Since it is possible to do the above with a simple structure, it also has the effect of being able to be implemented at extremely low cost.
