Description

The present invention relates to a conductor fitting for a conductor that is wired along a support.

Conventionally, lead wire fittings are widely known. For example, it is widely known including a conductor fitting for a conductor wired along a support shown in Patent Document 1.
For example, the conductor fitting shown in Patent Document 1 is configured as follows.
A C-shaped gripping portion formed in an inner diameter corresponding to the outer diameter of the support; and a first constriction member and a second constriction member respectively extending in parallel from the two free ends of the gripping portion. A stenosis part, in which the first stenosis member and the second stenosis member in the stenosis part respectively have a stenosis part in which a hole for inserting a bolt is formed at a corresponding position, and the first stenosis part to hold a lead wire A gripping portion is formed by integrally molding a member and a holding portion provided at a tip portion of the second constriction member, and by inserting a bolt into a hole formed in each of the first and second constriction members and tightening the bolt. The holding portion is reduced so that the conductor is attached to the support (see, for example, Patent Document 1).
The lead wire fitting of the above configuration can be held in a state where the lead wire is in line with the support in use, as well as a lead wire (for example, a parallel feeder) to be attached at a high frequency away from the metal support. There is an advantage that it can be held without being affected by high frequency from the support made of steel.

Design Registration No. 528196

In use, this conventional conductor fitting is removed from the bolt and the bolt is removed.
Next, the holding | maintenance part of a conducting wire fixture is expanded, the opening | mouth of a holding part is opened, a holding part is fitted to the outer periphery of a support | pillar, and a conducting wire is located inside a holding part.
After that, there was a troublesome work problem that had to be pierced through the hole of the narrowed portion again and screwed with the thumbscrew to be tightened. There was also the problem of dropping the bolts and losing them.
Further, in the field, when the outer diameter size of the support column is different from the planned size, there is a problem that the lead wire fitting does not correspond to the support column and the prepared wire fitting cannot be used immediately.

The purpose of the present application is not only to hold the conductor in a state where it is in line with the support, but also to a conductor (for example, a parallel feeder) to be mounted at a high frequency away from the metal support. It is an object of the present invention to provide a conductor fitting that can be held without being affected.
Another object of the present invention is to provide a conductor fitting that can be quickly attached when the fixture body is attached to the support column.
