Abstract: A shielded connector includes a housing having a front opening portion and an electric wire insertion portion, a terminal to be accommodated in a terminal accommodating portion of the housing and to be connected to a mating terminal, a connection terminal to be connected to an electric wire, a first shielding shell to cover a rear surface of the housing, a second shielding shell having a braid connection portion and a shell fixing portion to be connected to the first shielding shell, a first fastening member to fasten the housing to the first shielding shell, a second fastening member to fasten the connection terminal to the terminal, and a third fastening member to fasten the shell fixing portion to the first shielding shell. The first, second and third fastening members have fastening directions parallel to each other, and are fastened from a front surface side of the housing.

Abstract: A fuse (1) includes a fuse element (10) having a fusible portion (13) provided between opposed inner edges (11a, 12a) of flat plate portions (11, 12), and an insulating housing (50) covering the inner edge sides of the flat plate portions and the fusible portion in a state in which outer edge (11c, 12c) sides of the flat plate portions are protruded outward from slits at respective end walls (55, 58) of the insulating housing (50). The outer edge sides of the flat plate portions are formed as terminal portions (21, 22) each having a thickness twice as large as the thickness of the flat plate portion, and protrusions (11b, 12b) provided on upper and lower edges of the flat plate portions abut against inner surfaces of the end walls (55, 58) of the insulating housing (50).

Abstract: A locking portion (13) is provided to lock an open/close cover (15) to a fuse unit (5) or a cover main body (9) assembled to the fuse unit (5) in a state where the open/close cover (15) is closed. The open/close cover (15) is openably and closably connected to the cover main body (9), and includes first and second side walls (17, 19) respectively on both end sides in an orthogonal direction orthogonal to an opening/closing direction and extending in the opening/closing direction. The locking portion (13) includes a locking protrusion (21) provided in the first side wall (17) deformable in the orthogonal direction, and a mating locking protrusion (23) provided in the fuse unit (5) or the cover main body (9) and facing the first side wall (17).

Abstract: A battery cover includes first and second cover portions and a coupling portion that is arranged in a position lower than upper surfaces of the first and second cover portions, between the first and second cover portions. The coupling portion includes a connection portion that is fixed to the second cover portion and a hinge portion that is thinner than the connection portion. The hinge portion is provided such that hinge end portions on both sides are thicker than a hinge center portion. Each of the hinge end portions is formed such that a side end surface thereof is a curved surface which is gently inclined from the first cover portion to the second cover portion and that an upper surface thereof is formed into a substantially arc-shaped curved surface which is thinnest in its center and inclined upward to gradually become thicker from the center toward both support ends.

Abstract: A producing method for producing zirconia hollow particles in which a zirconia powder mutually combines to form a porous shell layer thereby constructing a hollow structure, the method being characterized in mixing under a pressurized contact a resin powder and a zirconia powder of a grain size smaller than that of the resin powder, thereby forming a precursor by covering a surface of the resin powder with the zirconia powder in a partially embedded state, and calcining the precursor to expel the resin powder and to mutually sinter the zirconia powder.
