Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a connection terminal box auxiliary clamp used in the work of rehanging overhead communication lines. [Prior art] Conventional technology of this kind includes an overhead communication line in which a new suspension line is laid parallel to the old suspension line on which the connection terminal box is hung, and the connection terminal box is replaced on the new suspension line. In the suspension wire replacement work, the connection terminal box was once dismantled, the old suspension wire was removed, and the suspension wire was replaced with a new suspension wire. That is, as shown in the partially cutaway explanatory diagram of FIG. 3, first remove the cover 13 and cable tie 14 of the connection terminal box 30, which is suspended from the old hanging wire 12 with the cable tie 14, and then No. 2 protective PVC tape 15,
After removing the sealing tape 16, nozzle lock 17, side wall clamp 18, and side wall 23 in this order, loosen the fixing bracket 19, and remove the old hanging wire 1 from the connection terminal box 30 .
2 was removed, and then the connection terminal box 30 was attached and hung to another new suspension wire in the reverse order of the procedure described above. [Problems to be solved by the invention] However, with the above-mentioned conventional technology, (1) installation and removal work takes time, and in particular, the sealing tape is sticky and difficult to peel off, so it takes a lot of time to remove it. . (2) Furthermore, for installation to the new suspension line,
If the sealing tape and the nozzle on the side wall are not properly formed, there is a problem that the case will be distorted and the cover will be difficult to fit into.The present invention aims to solve these problems. In other words, the purpose of the present invention is to solve the above-mentioned problems when re-spanning the suspension wires of overhead communication lines, and to shorten the work time and reduce costs when relocating the connection terminal box to a new suspension wire. be. [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention allows the connection terminal box held on the old hanging wire to be replaced without being dismantled, and the following connection terminal box clamp is used. It was Nitano. That is, in the connection terminal box auxiliary clamp used in the hanging wire re-stretching work of an overhead communication line, in which another new suspension wire is laid horizontally in parallel to the suspension wire on which the connection terminal box is hung, and the connection terminal box is re-strung on the new suspension wire, A member for holding the suspension wires and new suspension wires near both sides of the connection terminal box, which member is fitted with a round head bolt and a threaded portion of the round head bolt, and is connected to the vicinity of the head of the threaded portion and the other end. A set of hanging wire fixing hardware provided nearby, a set of tightening means screwed onto the inner threaded portion of the hanging wire fixing hardware and tightening the hanging wire fixing hardware facing outward, and an end face of the threaded portion of the round head bolt. The hanging wire fixing hardware consists of a member A and a member B that are divided into two parts in the axial direction of the threaded part, and supports the hanging wire in parallel to the hanging wire on the upper part of the opposing inner surfaces of the members A and B. The connection terminal box auxiliary clamp was constructed such that the opening/closing support point was provided at the lower end of the inner surface with one protruding to the opposing surface and the other forming a recess, and the outer surfaces of the members A and B were formed in an arc shape. It is. [Function] Since the present invention is configured as described above, it is possible to use the connecting terminal box clamp implementing the present invention to hold the connecting terminal box on the new hanging wire while holding it on the old hanging wire. There is no need to dismantle, remove, and reinstall the connection terminal box as in the past, and the work time required for relining work can be shortened. [Example] An example of the present invention will be described with reference to the drawings. FIG. 1A is a front view of an embodiment of the invention, FIG. 1B is a side view of an embodiment of the invention, and FIG. 2 is an explanatory diagram of an embodiment of the invention. In FIGS. 1A and 1B, 1 is a round head bolt and 2 is a threaded portion. Although the round head bolt 1 is not necessarily limited to a round head, a round head bolt is used so that there is no damage even if the bolt comes into contact with surrounding objects. The threaded portion 2 extends from the head of the round head bolt 1 and extends a predetermined length to the end. 3 is a hanging wire fixing hardware, 4 is a fixing member A, 5 is a fixing member B, 6 is a tightening means, 7 is a groove, 8 is an opening/closing support point, 9 is an arc, and 10 is a fixing nut. The hanging wire fixing hardware 3 is composed of a member A4 and a member B5 which are divided into two parts in the axial direction of the threaded part 2, and are loosely engaged with the threaded part 2. Also, member A4 and member B5
At the upper part of the inner surface facing the
Groove 7 that supports the new suspension wire so that it is parallel to the direction of
Also, the tip of one fixing member A4 at the lower tip of the inner surface protrudes to the opposing surface, and the tip of the other fixing member B
5 is formed in a concave portion, and both form an opening/closing support point 8. Two hanging wire fixing hardware 3 are loosely connected to the threaded part 2 of a single round head bolt 1, and one hanging wire fixing hardware 3 is placed under the neck of the round head bolt 1, and the other hanging wire fixing hardware 3 is loosely connected to the threaded part 2 of a single round head bolt 1. 3 is loosely fitted near the end face of the threaded portion 2 of the round head bolt 1, and tightening means 6, 6 are screwed into the intermediate threaded portion 2 in contact with the inner end of the hanging wire fixing hardware 3, respectively. . A fixing nut 10 is fixed to the end of the threaded portion 2 by appropriate known means. The fastening means side of the fixing member B5 is formed in an arc shape. Connection terminal box auxiliary clamp 4 according to an embodiment of the present invention
0 is constructed as described above, and as shown in FIG. The old suspension wire 12 and the new suspension wire 20 are inserted into the groove 7 and held by the tightening means 6, the old suspension wire 12 is removed on both sides of the connection terminal box auxiliary clamp 40 , and the cable is attached to the new suspension wire 20 with the cable ring 21.
By gripping the connection terminal box 30, the connection terminal box 30 can be gripped onto the new suspension wire 20 without being dismantled. [Effects of the invention] As explained above, the new suspension wire can be held together with part of the old suspension wire using the connection terminal box auxiliary clamp according to the present invention without disassembling the connection terminal box (1)
Reduce working time. (2) Construction costs can be reduced.
(3) Problems such as distortion of the connection terminal box due to disassembly and difficulty in attaching the cover are eliminated.
