う問題点があつた。(Problems to be Solved by the Invention) This type of wire extension and wire tensioning connector connects the insulator link to the wire extension connector and insulator link portion immediately before the completion of the tensioning, that is, in a temporary tensioning state. must be fitted with metal fittings. However, when the conventional line extension and tension line connecting devices are connected,
The wire is tied by applying the side edge of the tensioning connector to the step surface of the constriction step of the main body of the connecting device for wire extension and tensioning, so It will not be in a straight line but will be bent. For this reason, both the devices of Conventional Example 1 and Conventional Example 2 are strained. Furthermore, in Conventional Example 2, there was a problem in that the clamp protector was also twisted because it was bent between the tension clamp and the wire stretching and tensioning connector.
