Abstract: A housing body contains the fuse body therein. The fuse body is formed with an opening and a retaining projection arranged in the vicinity of the opening. A cover body is formed with a locking piece adapted to engage with the retaining projection so that the cover body closes the opening. A rigidity-reduced portion is formed in the cover body, so that the cover body can be flexed substantially without flexing the locking piece, at least when the locking piece engages with the retaining projection.

Abstract: A short plug-in fuse, having a fuse body received within an insulating housing, is fitted into a short fuse cavity of an electric connection box, so that the fuse body is connected to tab terminals projecting from an inner bottom surface of the fuse cavity. The short fuse cavity is set to a small fitting depth in corresponding relation to the short plug-in fuse, and a pair of guide grooves are formed in each of opposed inner side surfaces of the short fuse cavity, and extend in a fitting direction. A pair of guide ribs for respectively fitting into the corresponding pair of guide grooves are formed on each of parallel opposite outer side surfaces of the short plug-in fuse.

Abstract: A first housing is formed with a cavity adapted to receive both of a second housing having a first length and provided with a first fuse, and a third housing having a second length smaller than the first length and provided with a second fuse. The cavity has a bottom. A pair of terminals are extended from the bottom of cavity so as to have a third length. The terminals are adapted to be fitted with both of the first fuse and the second fuse. At least one spacer having a predetermined thickness smaller than the third length is removably disposed on the bottom of cavity, at least in a case where the third housing is received in the cavity.

Abstract: A rotating terminal (16) has a circumferential outer peripheral surface (21a, 24a) having its center disposed at an axis (13, 21b) of rotation of the rotating terminal, and has electrically conductive areas and non-electrically conductive areas alternately arranged on the outer peripheral surface in the circumferential direction. At least one pair of fixed terminals (17, 18) are fixed and disposed outwardly of a path of rotation of the outer peripheral surface of the rotating terminal. In accordance with a rotating position of the rotating terminal, the pair of fixed terminals can be switched between an electrically-conducting condition, in which the pair of fixed terminals are electrically connected together through the rotating terminal, and an interrupting condition in which the pair of fixed terminals are not electrically connected together through the rotating terminal.

A middle portion (21f) of each of the flat-plate terminal portions (21), located at the lateral position relative to the fusible portion (22), is fixedly gripped by a mating terminal (11) of a fuse mounting portion, so that the flat-plate terminal portion is electrically connected to the mating terminal.

Abstract: A fuse includes a fuse element contained in an insulating housing made of synthetic resin. The insulating housing which includes a pair of housing bodies and an upper wall portion mutually connecting upper ends of the housing bodies is adapted to cover inner edges and upper edges of flat plate terminal portions and a fusible portion. On one side edge of a slit opening formed at a lower end of the insulating housing, a flap is continuously provided through a thin-walled hinge so as to freely rotate. The flap is rotated to a closed position in a state where the fuse element has been inserted into the insulating housing, and locked to locking projections which are projected from the inner edges of the respective flat plate terminal portions. The distal end edge of the flap which is abutted against the other side edge of the slit opening is joined by ultrasonic welding, thermal welding or the like.

Abstract: A fuse 1 includes a pair of terminals 2, housing 4 and fusible body 5. The terminals 2 are provided so that their one ends are housed in the housing 4 and their other ends are exposed externally from the housing 4. The terminals 2 each has a recess to enlarge the interval therebetween. The recess 6 consists of a flat face 10 and step face 11. The housing 4 includes a pair of end walls 12a, 12b, and a pair of partition walls 22. The inner faces 15a, 15b of the pair of end walls 12a, 12b are opposite to each other in a direction orthogonal to the direction the pair of terminals are arranged in parallel and extend along the end faces of the terminals 2. The partition wall extend from the inner face 15b toward the inner face 15a. The second partition walls each covers the flat face 10. In this configuration, when the power with a current value which exceeds the fusing current value of the fusible body is supplied, supply of the power to the load can be surely stopped.
