Abstract: Automotive-type fuse for large currents, in which a generally rectangular metal strip of tin-plated zinc, with a central portion shaped to form a conductor of smaller conducting cross section, is provided, at each of its opposite ends, with a circular hole for the screw of an electrical terminal clamp, this hole being surrounded by an annular insert caulked into the strip, made of metal, such as copper with tellurium or with beryllium, with a modulus of elasticity and yield-point stress higher than that of zinc, to ensure the stability of the screw clamp, even under vibration, with a clamping pressure greater than the yield-point stress of zinc, by means of the elastic reaction exerted by the ring.

Abstract: A fuse carrier comprises a plurality of sockets for reed-type fuses, each socket being provided with a pair of electrode clips adapted to provide support and electrical connection for each fuse. The electrode clips configured to accommodate a microlamp which is connected in parallel to the fuse. The lamp therefore illuminates whenever the fuse burns out.

Abstract: An adapter base for reed-type fuses, of the kind usually installed in fuse carriers on passenger cars, comprises a pair of blades each provided at one end with a socket, and a microlamp having rheophores each connected electrically to a respective one of said blades.The adapter base can be retrofitted to passenger car fuse carriers and affords illumination of a burned out fuse from the time when the failure occurs.
