  The rotating base accommodating portion S2 is an accommodating portion that defines a space in which the attachment member 3 can rotate around the axis L together with the rotating base 33. The rotating base accommodating portion S2 is constituted by a cylindrical portion 8 formed by combining the cylindrical portion constituting portions 81 and 82 when both the cover pieces 11 and 12 are closed. The inner diameter of the cylindrical portion 8 is set such that the rotation base 33 and the front side portions of the linear portions 32 and 32 of the attachment member 3 can rotate about the axis L. A plurality of reinforcing ribs 81a and 82a along the circumferential direction are provided on the outer peripheral surfaces of the cylindrical partial constituent portions 81 and 82 at appropriate intervals along the axis L direction. The reinforcing ribs 81a and 82a contain a rotating body such as the rotating base 33 in the cylindrical portion 8, so that stress is applied to the cylindrical portion constituting portions 81 and 82 as the rotating bodies rotate. Therefore, it is provided to reinforce this. A circular opening 80 is formed in the front side portion of the cylindrical portion 8 so as to allow communication between the internal space of the rotating base housing portion S2 and the outside. The lid 4 is provided in the opening 80.

It can be made to respond to this. That is, each of the plurality of plate-like pieces 43 and the rib-like plate-like pieces 44 constituting the lid portion 4 is made of a soft resin that can be elastically deformed, and is divided through a dividing line L1, and is further divided into slits 43a, Since each of the first and second slits 44a and 44b can be elastically deformed individually, the mounting member 3 can be easily rotated with the elastic deformation of the plate-like piece 43 and the rib-like plate-like piece 44. Made. In this case, the rib-like plate-like piece 44 is easily elastically deformed because its plate surface comes into contact with the linear portion 32, and the rotation of the mounting member 3 around the axis L is less resistant. On the other hand, since the edge of the plate-like piece 43 abuts on the linear portion 32, the plate-like piece 43 itself has a large resistance in the surface area direction, and the plate-like piece 43 is less likely to be elastically deformed.

  The plate-like piece 43 and the rib-like plate-like piece 44 may be provided so as to be opposite to the exemplified positional relationship along the axis L direction.

  In the present embodiment, the lower edge engaging portion 14 includes a plate-like insertion claw piece 14 a projecting from the lower edge portion 11 b of the left cover piece 11 so as to face the right cover piece 12, and a lower portion of the right cover piece 12.

It consists of the to-be-latched piece 15b projected so that it may face upwards. The insertion claw piece 15a has a claw portion 15aa on the upper surface of the tip thereof, and the locked piece 15b has a locking hole 15ba into which the insertion claw piece 15a can be inserted. Here, the upper and lower directions indicate the upper and lower directions in a state where the clamp cover body 10 is attached to the tension clamp 2 and the cover pieces 11 and 12 are closed.

  When the cover pieces 11 and 12 are closed by the lower edge engaging portion 14 and the intermediate engaging portion 15 having such a configuration, the insertion claw pieces 14a and 15a are gripped by using an indirect tool such as a bark. Then, they are inserted into the locking holes 14ba and 15ba of the locked pieces 14b and 15b, respectively, and the claw portions 14aa and 15aa are locked to the hole edges of the locking holes 14ba and 15ba. Thereby, both cover pieces 11 and 12 are maintained in a closed state. The closing operation of the cover pieces 11 and 12 using such an indirect tool is extremely safe.

The diameter of this circumference is set to be approximately equal to the distance between the axes of the two linear portions 32. The lid component parts 41 and 42 are formed so as to be symmetric with respect to the dividing line L1.

  Therefore, when the clamp cover body 10 having the lid portion 4 configured as described above is attached to the tension clamp 2 with the attachment member 3 connected thereto, and both the cover pieces 11 and 12 are closed, the plate-like piece 47 can be elastically deformed so that the linear portion 32 of the mounting member 3 can be accommodated in either the circular hole 46 a or the circular hole formed by the notch 48. FIG. 9A shows a state in which the linear portion 32 is accommodated in a true circular hole formed by the notch 48. When the mounting member 3 is rotated around the axis L according to the direction of the distribution insulator 7 from the state in which the linear portion 32 is accommodated in the perfect circular hole formed by the notch 48 in this way, the linear portion 32 is formed. The abutting plate-like pieces 47 are successively elastically deformed, and the linear portion 32 can be accommodated in a true circular hole at an appropriate position. Further, since the lid portion 4 closes the opening of the cylindrical portion 8, the invasion of birds and beasts and insects into the space S is prevented, and damage caused by these is prevented.

  10 and 11 show a clamp cover main body 10 according to another embodiment of the present invention, FIG. 10 is a perspective view of the clamp cover main body 10 viewed from the inside, and FIG. 11 is the clamp in the open state. 4 is a bottom view of the cover body 10. FIG. In the clamp cover main body 10 of this embodiment, the configurations of the lower edge engaging portion 14 and the intermediate engaging portion 15 are different from those of the above embodiment, and other configurations are the same as those of the above embodiment. Therefore, the same reference numerals are given to the parts common to the above-described embodiment, the description thereof is omitted, and only different parts will be described below.

  In this embodiment, the lower edge engaging portion 14 includes a plate-like engaging operation piece 14c provided on the lower edge portion 11b of the left cover piece 11 via a hinge portion 14ca, and a neck on the lower edge portion 12b of the right cover piece 12. It consists of a substantially four hemispherical engaging protrusion 14d provided via a portion 14da. The plate-like engagement operation piece 14c is formed with a half-moon shaped locking hole 14cb having a diameter slightly smaller than the maximum diameter of the engagement protrusion 14d. The intermediate engagement portion 15 includes a plate-like engagement operation piece 15c provided on the intermediate edge portion 11c of the left cover piece 11 via a hinge portion 15ca, and a neck portion 15da on the intermediate edge portion 12c of the right cover piece 12. And an approximately four hemispherical engagement protrusion 15d. The plate-like engagement operation piece 15c is formed with a half-moon shaped locking hole 15cb having a diameter slightly smaller than the maximum diameter of the engagement protrusion 15d.

  When both the cover pieces 11 and 12 are closed by the lower edge engaging portion 14 and the intermediate engaging portion 15 having such a configuration, the plate-like engaging operation pieces 14c and 15c are used by using an indirect tool such as a bark. And the plate-like engagement operation pieces 14c and 15c are rotated to the right cover piece 12 side via the hinge portions 14ca and 15ca. Then, the plate-like engagement operation pieces 14c, 15c are further rotated so that the engagement protrusions 14d, 15d are press-fitted into the locking holes 14cb, 15cb of the plate-like engagement operation pieces 14c, 15c. When the engaging protrusions 14d and 15d are completely fitted into the locking holes 14cb and 15cb, respectively, the neck portions 14da and 15da of the engaging protrusions 14d and 15d are engaged with the hole edges of the engaging protrusions 14d and 15d, respectively. Stopped. Thereby, both cover pieces 11 and 12 are maintained in a closed state. The closing operation of the cover pieces 11 and 12 using such an indirect tool is also extremely safe.

  The outer shape of the clamp cover main body 10 is not limited to the shape shown in the figure, and other shapes can be employed. Further, the engaging mechanism of the lower edge engaging portion 14 and the intermediate engaging portion 15 is not limited to the illustrated one, and other engaging mechanisms can be adopted from the start. Furthermore, it is possible to adopt other shapes and configurations for the shape of the mounting member 3 and the configuration of the lid 4. In addition, in the embodiment, the example in which the lid portion 4 is provided in the opening 80 of the cylindrical portion as the accommodating portion has been described, but such a lid portion 4 may be omitted depending on the specification.
