６に継げば良い。 When attaching the above structure to the messenger wire 10 suspended in the air, first loosen the fixing nut 19. In the loosened state, lift the side of the fixing piece 12 on which the groove 13 is provided as shown in FIG. Next, the messenger wire attachment portion 7 is positioned so that the messenger wire 10 is inserted between the groove 9 in the base 8 and the groove 13 in the fixing piece 12. After positioning in this way, attach the fixing piece 1 to the messenger wire 10.
The grooves 13 of No. 2 are brought into contact with each other. In this state, tighten the fixing nut 19 and connect the groove 9 in the base 8 with the fixing piece 12.
The messenger wire 10 is tightened by the groove 13 at. When tightening the fixing nut 19, the threaded rod 11 is passed through the elongated hole 14 in the fixing piece 12, and the guide piece 16 provided on the fixing piece 12 faces the convex piece 15 set up from the base 8. Therefore, even when the fixing nut 19 is rotated, the fixing piece 12 is prevented from rotating together, and the fixing nut 19 can be easily tightened. This fixes the housing 1 to the messenger wire 10. In addition, when tightening the fixing nut 19, since a groove 13 is provided on the fixing piece 12, the housing 1 will not move even if the groove is pulled onto the messenger wire 10 and the housing 1 is released. Accidental falls are prevented. After the housing 1 is attached to the messenger wire 10 in this way, as is well known, the cables on the input side or the output side, as well as the cables on the branch distribution side, are connected to the respective connectors 5,

損じない実用効果もある。 As described above, in this invention, the threaded rod 1 is placed in the hole 14 that is opposed to the pedestal 8 and is bored in the pedestal 8.
In the fixing piece 12, which passes through the threaded rod 11 and is freely movable toward and away from the pedestal 8, the hole 14 through which the threaded rod 11 passes is elongated toward the insertion port I of the messenger wire 10. When the housing 1 is attached to the messenger wire 10 during field use, the fixing nut 19 attached to the threaded rod 11 is slightly loosened to allow the tightening piece 12 to lift. If possible, since the through hole 14 is a long hole, the gap H on the side where the messenger wire 10 is inserted is widened, and the messenger wire 10 is formed between the clamping piece 12 and the pedestal 8. It has a feature that makes the work of introducing it into the grooves 9 and 13 extremely simple. This is fixed nut 1
9. It has the operational effect of significantly reducing the effort for loosening and also reducing the effort for tightening. Furthermore, because of the above-mentioned structure, in the work of introducing the messenger wire 10 between the clamping piece 12 and the pedestal 8, the introduction-side mouth 12' of the clamping piece 12 opens at a large angle, so that it has a funnel shape. Thus, it plays the role of a guide and has the effect of facilitating the introduction of the messenger wire 10 into the groove. Furthermore, when the introduction side of the tightening piece 12 is made wide open as described above, that is, when the tightening piece 12 is inclined to receive the messenger wire 10, the groove 9 in the tightening piece 12 and the pedestal 8, 13 and the distance between the tightening pieces 12 and the introduction side of the pedestal 8 are almost equal to each other, so even when the messenger wire 10 is introduced and positioned in the groove, It also has the feature that it prevents large wobbling from occurring, and as a result, it can exhibit a temporary fixing effect. This is a very dangerous situation for workers who have to install the housing 1 with their bodies hanging from the messenger wire 10 in the air, as the messenger wire 10 is normally in the air. The above-mentioned temporary fixing effect is a great benefit and exhibits an epoch-making effect in preventing crashes. Furthermore, since a convex piece 15 and a concave part 15' that face each other and engage with each other are formed on the side opposite to the side of the insertion opening I, the fixing nut 1 can be tightened while the tightening piece 12 is lifted.
There is an advantage that the tightening piece 12 does not rotate together even when turning the knob 9, and even if the convex piece 15 and the recessed part 15' are formed, both sides 12a, 12 of the tightening piece 12
There is also a practical effect that does not impair the operational effect of being able to lift and operate b by picking it up with your fingers.
しかも本願考案にあつては、締付片１２を持上

特長があり、その結果、固定用ナツト１９を台座

ることのできる効果がある。 Moreover, in the present invention, when the tightening piece 12 is lifted to open the insertion port I, the threaded rod 11 has a structure in which the lower end is embedded in the pedestal part 8 and the free end side is screwed. It has the advantage that a sufficiently long one can be used to enlarge the opening of the insertion port, and as a result, the fixing nut 19 can be spaced far upward from the pedestal part 8 to obtain a large opening. be.

The fixing nut 19 is raised relative to the threaded rod 11, and the lifting limit is visible, so it is possible to see when the fixing nut 19 is about to come off the upper end of the threaded rod 11 (when the fixing nut 19 is This also has the effect of preventing the rod from coming off the rod 11 and falling to the ground.

のネジ山が潰れてしまつて締付が不能となつてし
まう問題点があつたのに対し、その問題点を解消
できる有用性がある。 Furthermore, in the state shown in FIG.
When the screw rod 11 is strongly fastened, the large-diameter head of the lower end of the screw rod 11 is embedded in the base portion 8 beforehand, so that the screw rod 11 is firmly integrated with the base portion 8, and it is possible to very strongly fasten the fixing nut 19. This is because in the conventional structure shown in Fig. 5 (similar to that shown in, for example, Japanese Patent Application Laid-Open No. 51-86340 and Japanese Utility Model Application Laid-Open No. 52-10744), the threaded portion of the screw rod 11f is screwed into the female screw hole 21 formed in the base portion 8f, and therefore the fine screw hole 21 is relatively weak, and when the screw rod 11f is strongly fastened, the screw hole 21
The screw threads of the fasteners used in the past could become stripped, making it impossible to tighten the fasteners.
更にまた上記のように大きな頭部を台座部８に
埋込んだということは、上記挿入口Ｉの開口寸法

ある。 Furthermore, the fact that the large head is embedded in the pedestal part 8 as described above means that the length of the threaded rod 11 is increased in order to increase the opening size of the insertion port I. A good feature is that the size of the head embedded in the head is small. This means that if the length of the threaded rod 11f is increased in order to increase the opening size in the conventional configuration, the length L of the screw hole 21 must be increased, and for this purpose, the pedestal This has the effect of helping to solve the problem that the thickness of 8f must be increased according to its dimension L.
