で、作業性が極めて悪かつた。(Prior Art) When attaching a fuse with a claw to a fuse holder, it has been common to press the fuse holder by hand and then tighten and fix the tightening bolt. For this reason, the fuse holder must be held by hand until the tightening bolt is tightened, resulting in extremely poor work efficiency.

うるようにした。(Solution by invention) In a fuse mounting device that consists of a case with a U-shaped vertical section and a fuse holder with a claw-fitted fuse attached to the bottom, the central contact part of the fuse holder is A resin spring having a bulging spring portion is fixed to the upper edge of the side wall of the case in accordance with the above, and the fuse holder is pushed in against the resin spring, and the fuse holder makes contact with the lower part of the curved spring portion of the resin spring. The parts were made to touch each other. This makes it possible for the fuse holder equipped with the characteristic temporary holding device to prevent the holder from coming off upward during temporary holding, and to maintain contact with the bus bar.

The claw portion 4a of the claw-equipped fuse 4 is held between the threaded washer 5 fitted to the lower part of the fuse holder and the lower end surface of the fuse holder. Note that the threaded part of the threaded washer 5 is provided to allow the threaded part of the tightening bolt 3 to pass through, and when the claw part 4a is being held, it does not screw into the threaded part but loosely fits into the shaft part. There is.

る。 Now, reference numeral 6 denotes a resin spring fitted to a side wall of the fuse holder 1 of the case 2, which corresponds to the contact portion 1a at the exact center. The resin spring 6 is composed of a mounting portion 6a that is fitted onto the upper edge of the case 2, and a curved spring portion 6b that bulges inside the case 2, and is provided facing the upper edge of the case. Numeral 6c is a protrusion that engages with a hole 2a drilled near the upper edge of the case, and is thereby firmly positioned and attached to the case 2.

通した仮保持状態となる。 The claw part of the clawed fuse is held in the lower part of the fuse holder 1 with a washer 5, and this is pushed into the case 2. Then, the contact portion 1a (FIG. 2) of the fuse holder 1 presses the curved spring portion 6b of the resin spring 6, causing it to deform and fit into the resin spring. Contact portions 1 with the resin springs 6 on both sides of the center portion of the fuse holder 1
A is temporarily held at a point just beyond the spring portion 6b. In this position, the upper corner of the contact part 1a of the fuse holder is in contact with a position below the center of the resin spring 6, and the reaction force P1 of the spring generates a downward pressing force P2 , which pushes the washer against the busbar. This prevents arcing before the tightening bolt 3 is tightened. Of course, in this state, due to the presence of the curved spring portion, it will not come off upward, and the claw-fitted fuse 4 will be in contact with the bus bar 7, and will be in a temporarily held state in which it is electrically conductive.

きるようになつた。(Effects) A resin spring attached to the case provides a temporary holding function when a claw-type fuse is installed, mechanically pressing the entire fuse holder against the bus bar and making electrical contact, making it easier to tighten the tightening bolt. Compared to the conventional structure, which required the user to hold the fuse by hand until it was tightened, the claw-type fuse device is much more efficient and can prevent arcing during installation.
