In the case where a braid (14) is used as a shielding sheet covering wires (10) over their entire length, a distal end portion of the braid (14) is connected to a mounting member (B) connected to the ground (G), thereby achieving an electromagnetic shielding conduction. At this time, the distal end portion (14a) of the braid (14) is spread outward, and is engaged in an annular groove (20b) of a channel-shaped cross-section in a housing (20), and a braid retaining band (22) is wound on an outer surface of the distal end portion (14a) of the braid (14), and is tightened to fasten this distal end portion. As a result, the distal end portion (14a) can be positively and firmly connected to the mounting member (B), and the effective electromagnetic shielding effect can be expected, and the stable electrical characteristics can be obtained, so that the reliability of the connection can be enhanced.

A bundle of electric wires has a first length and a first diameter. A tubular braided wire has a second length which is shorter than the first length and a second diameter which is larger than the first diameter. The bundle of electric wires is passed through the braided wire, and then a connector is connected to each of both ends of the electric wires collectively. The connector having a third diameter which is larger than the first diameter. The braided wire is stretched such that both ends thereof are fixed on the respective connectors to form a reduced-diameter portion therebetween which is fitted on an outer periphery of the bundle of the electric wire. A conductive retainer is attached on the reduced-diameter portion to maintain a length and a diameter of the reduced-diameter portion.

A power supply shut-off apparatus includes a service plug 2 detachably mounted to a plug mounting portion 14 provided in an apparatus body 1, and the power supply-side switches between a conduction state and a nonconduction state between a load-side bus bar 3 and a power supply-side bus bar 4. When the plug housing 40 is mounted to the plug mounting portion 14 and the tilting lever 41 is tilted down substantially horizontally in a state where the tilting lever 41 of the service plug 2 is held in the substantially vertical state, the shaft 49 provided on the tilting lever 41 falls the movable lever 32 of the microswitch 15 so as to allow the microswitch 15 to detect the conduction state between the load-side bus bar 3 and the power supply-side bus bar 4.

A connecting structure for interengaging metallic shielding members is provided, which includes: a contacting elongation (2) at a leading edge of a cylindrical male metallic shielding member (1); a mating contacting elongation (4) at a leading edge of a cylindrical female metallic shielding member (3) which is brought into contact with the male member contacting elongation at the leading edge of the cylindrical male metallic shielding member; and a pair of engaging hook pieces (5) formed to extend circumferentially on the contacting elongation of one of the metallic shielding members to engage with the contacting elongation of the other metallic shielding member, wherein the pair of engaging hook pieces are formed at both sides of a slit (6) provided between the adjacent contacting elongations. The contacting elongation of either of the metallic shielding members is urged toward and into tighter contact with the contacting elongation of the other metallic shielding member by a pressing spring portion (23) provided on a housing (17′) of a connector (19).

A shield wire, having a shield mesh whose front end portion is folded back, is inserted into a shield contact member from a rear side thereof, so that the shield mesh is fitted in a wire fixing portion, and is fixed thereto at a spiral groove portion. Then, a terminal is fixedly secured to a front end of the shield wire, and the terminal is inserted into an electrically-conductive, hollow cylindrical shell, mounted within a housing, through an open, exposed rear end of the shell, so that a shell contact portion of the shield contact member is held against the rear end, and in this condition the shield wire is fixed to the housing.

To make the fitting of a pair of connectors smooth and keep an insulation distance between a terminal and a metal shell large and thus improve the fitting characteristics and the reliability of a shielded connector, a rib projects over the end surface of one of a male or a female connector so that the rib lies between a metal shell projecting over the end of the male connector and a male terminal projecting over the end surface. A groove corresponds to the rib and is formed in the top end surface of the other of the male and female connectors.
