From the small frame extend two wings shaped in such a way as to allow the easy insertion between themselves of the fuse and the subsequent elastic restraint of the fuse.

Abstract: This support is for mounting on structure of electrical apparatus a fuse or other device that comprises a cylindrical tube. The support comprises a base adapted to be secured to said structure, the base having a length and a width dimension. Two legs project laterally from the base at its longitudinally-opposite ends, each leg comprising a body portion that has a proximate end and a distal end. The base and the legs are of rigid polymeric insulating material, and the body portion of each leg is integrally joined to the base at the proximate end of the body portion. At its distal end the body portion of each leg carries a flange that projects from the body portion longitudinally with respect to the base. Each flange has a concave arcuate surface facing away from the base that is adapted to receive a portion of the above cylindrical tube. The arcuate surface includes a first curved portion for receiving a relatively large diameter tube and another curved portion for receiving a relatively small diameter tube.

Abstract: An automotive fuse includes a pair of spring clips connected by a fusible bridge and a transparent shield extending laterally over the width of at least the bridge and a face of one of the clips. The shield is connected to only one of the clips, so that the other clip and any associated lead fall freely from the fuse when the bridge fuses in response to excessive current. The clips are adapted for engagement with matching clips on hot or utility leads in the circuits to which the fuses are connected. The shield can be tinted with color to correspond to the amperage rating of the fuse.
