  However, the connecting tool as described above is generally formed by using a metal material as a whole, and the tip end portion of the gripping tool such as an insulating tool is generally made of metal. Therefore, when the extension part is gripped using a gripping tool, it is slippery and it is difficult to maintain the gripped state. In particular, when attaching and detaching a trunk line and a branch line to and from the coupler, the coupler may be moved while holding the coupler, or the coupler may be pressed against the trunk line. Since the tightening member (bolt member) may be rotated with a ratchet or the like for indirect hot-wire work in the gripped state, the coupling tool may easily fall off from the gripping tool. For this reason, workability | operativity in the state which hold | gripped the connection tool using the holding means is bad, and when the connection tool falls off, there is a risk of coming into contact with other power distribution equipment.

  Therefore, the present invention is for indirect hot-wire work that can reliably hold the extended portion by using a gripping means such as an insulating jacket, and can improve the workability of the indirect hot-line work in the gripped state. It is an object to provide a connector.

The indirect hot-wire work connector according to the present invention is formed so as to extend from the connector main body and a connector main body configured to be able to connect an installed trunk line and a branch line that branches an electric circuit from the main line. In the indirect hot wire connection tool comprising: the extended part and a pair of spring members attached to the connector body at spaced apart positions so as to sandwich the connector body. A pair of spring member insertion holes formed so that each of the spring members can be inserted is provided at a position apart from the extension portion, and a pair of tip portions are configured to be able to contact and separate to hold the extension portion. An insertion hole is formed between the pair of spring member insertion holes so that at least one of the pair of tip ends of the gripping means can be inserted, and the spring member insertion hole is inserted into the spring member insertion hole. Spring member inserted through the spring member Wherein the of being formed in such a size becomes swingable toward or away from the inner in the insertion hole.

According to the indirect hot-wire work connector having such a configuration, the extension portion includes a pair of spring member insertion holes, and a pair of insertion holes configured to allow insertion of at least one tip portion of the gripping means. By providing between the spring member insertion holes , the extension portion can be reliably gripped when the extension portion is gripped using the gripping means.
Specifically, by inserting at least one tip of the gripping means into the insertion hole and closing the pair of tip ends of the gripping means, at least one tip of the gripping means is engaged with the insertion hole. For this reason, the state which hold | gripped the extension part can be easily maintained by maintaining the pair of front-end | tip parts of a holding means in the closed state. Thereby, the gripping means does not slip from the extension part as in the case of gripping the extension part with the gripping means, and can be stably gripped with less force. .

  Further, the spring member insertion hole is formed in such a size that the spring member inserted into the spring member insertion hole can swing in a direction in which the spring member is in contact with and away from the insertion hole inside the spring member insertion hole. Thus, it is possible to prevent the spring member from interfering with the distal end portion of the gripping means when the distal end portion of the gripping means is brought close to the insertion hole.
  Specifically, since the spring member can be separated from the insertion hole inside the spring member insertion hole when the distal end portion of the gripping means approaches the insertion hole, one distal end portion of the gripping means is used as the insertion hole. When inserting, it can suppress that a spring member and the front-end | tip part of a holding means interfere. For this reason, the extension part can be easily gripped by the gripping means.

  Moreover, it is preferable that the connection tool for indirect hot wire work concerning this invention is formed so that the said insertion hole may be located in the extension direction side of an extension part rather than a pair of spring member.

  According to the connection tool for indirect hot wire work having such a configuration, the insertion hole is formed so as to be positioned on the extension direction side of the extension part with respect to the spring member, so that the distal end portion of the gripping means is inserted into the insertion hole. In doing so, it can be suppressed that the spring member becomes an obstacle.

  Specifically, for example, when the entire insertion hole is located between the pair of spring members, the pair of distal ends of the gripping means are brought close to the insertion hole, and the gripping means approaches when inserting. Depending on the direction of movement, the tip of the gripping means may interfere with the spring member, and it may be difficult to securely grip. In particular, in the state where the connecting tool is attached to the installed trunk line and branch line, the direction in which the gripping means approaches may be limited depending on the position of other power distribution equipment, etc., and the gripping means is inserted into the insertion hole. When it approaches, the spring member may become an obstacle and it may be difficult to insert the tip of the gripping means into the insertion hole. However, since the insertion hole is located on the extension direction side of the extension part with respect to the spring member, it is possible to make the gripping means approach the insertion hole from various directions, and it is easy without being affected by the spring member. It can be gripped.

  As described above, according to the present invention, the extending portion can be reliably gripped using gripping means such as an insulating jacket, and the workability of indirect hot-line work in the gripped state can be improved. .
