摘要： A fuse for a high voltage/high current application, such as a hydro-electric vehicle ('HEV') application is provided. The fuse employs a variety of arc quenching features to handle a large amount of arcing energy that is generated when such fuse is opened due to a fuse opening event. In one embodiment, an insulative substrate, such as a melamine substrate, is metallized with a fuse element. The fuse element extends to multiple surfaces of the substrate. A fuse opening portion of the element is located so that the arcing energy is forced to travel along multiple insulative planes, increasing an impedance across the opening of the element and decreasing the likelihood of a sustained arc. Also, the substrate and element are disposed in a sealed housing, which is packed in one embodiment with an arc quenching material, such as sand.

摘要： A fuse link, useful above all as back-up fuse protection or as main fuse protection in motor vehicles, has two connecting elements with a fuse lead arranged therebetween and is enclosed in a housing. In order to improve its manufacture, its handling and its mechanical and electric properties, the connecting elements (2a, 2b) and the fuse lead (10) constitute a metal element made of a single piece of sheet metal or of assembled parts. In order to enclose the metal element in the housing (1), the inner areas of the connecting elements (2a, 2b), together with their bridging fuse lead (19), are laid in a first half (1a) of the housing (1), substantially flush with the parting plane (1e) of the housing (1), and are retained there in a predetermined position by positioning means (1c; 3, 5; 6, 7; 4). The second half (1b) of the housing (1) is then set as a lid on the first half (1a) of the housing to close the housing (1), is brought by positioning means (3) into a predetermined position in relation to the first half (1a) of the housing and is secured thereto.

摘要： A fuse includes an insulative housing (12, 14), terminals (16) extending through gaps (30) in the bottom of the housing, and a fusible element (18) having ends connected to both of the terminals (16). The housing includes a four-sided box (12) that is closed at the top and open on the bottom, and a lid (14) for closing the open bottom of the box that is smaller than the open bottom of the box so that, when the lid (14) is in place, two gaps are formed in the bottom and at opposite ends of the housing.

摘要： A miniature fuse of surface mount type having a stable pre-arcing time-current characteristic and a strong time lag characteristic, being easy to produce, and providing a constant pre-arcing time is provided. The main body is of rectangular ceramic construction of split type. A fusible member 60 (Ag:Cu:An=>50%:>20%>17%:>5% (weight ratio) wound around the ceramic rod 58 (Al 2 O 3 :MgO:BeO=>96%:>3%:>3%:
The end portion 76 of the fusible member 60 is engaged with the side surface of the casing. The upper ceramic casing 52 is laid on the lower casing, so that the cap 56 is fit onto the opposite ends of the main body. The end portion 76 of the fusible member 60 and the cap 56 are connected by welding. At the time of welding, projection 74 to be fit in the recessed portion 72 provided at the main body is formed at the cap 56, so that the cap 56 can be fixed to the main body.-

摘要： Automotive-type fuse for large currents, in which a generally rectangular metal strip (1) of tin-plated zinc, with a central portion shaped to form a conductor (4) of smaller conducting cross section, is provided, at each of its opposite ends, with a circular hole (2, 3) for the screw of an electrical terminal clamp, this hole being surrounded by an annular insert (35, 36) caulked into the strip (1), 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 (35, 36). The central portion (4) of the strip, having the function of a fusible element, is advantageously housed in an opaque plastic containment housing (9, 10) provided with two juxtaposed windows (23, 24), on opposite sides of the fusible element, so that the condition of the fuse can be checked visually, the windows being closed by transparent plastic shields (29, 30).
