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.

A terminal block includes: busbars connected to a device; a collar through which a fastening member is inserted; a housing integrally molded with the busbars and the collar; and a capacitor including a casing and a ground terminal protruding from the casing, the capacitor connected to the busbars, in which the housing houses the casing in a state where the ground terminal faces the collar so that the ground terminal and the collar can be fastened together to a metal case by the fastening member.

A shielding member attached to a shielding shell. The shielding member includes a first and a second plate portion. The second plate portion includes a first and second ends, a fastening hole at both ends and a protruding portion on the first end. The protruding portion is longer than a length of the second plate portion. When a plurality of shielding members are attached to the shielding shell, the first end with the protruding portion is overlapped with the other first end of the adjacent shielding member so that it is located on the outside. When the first end is overlapped with the other end of the adjacent shielding member so that it is located on the inside, the protruding portion interferes with the first plate portion of the adjacent shielding member. In this way, the shielding member having the configuration can prevent erroneous assembly to the shielding shell.

A butting surface () of a first butting terminal fitting () held by a first terminal accommodating member () is formed in a curved-surface configuration protruding toward a second butting terminal fitting () side held by a second terminal accommodating member (). A plurality of contact spring pieces (and) of the second butting terminal fitting () which are butted against the butting surface () and resiliently deformed are flat plate type leaf springs arranged on the same plane.

Abutting type connector

A wire harness includes a wire portion having three wires arranged in the same direction, connectors connected to both end portions of the wire portion, a middle portion installed in an intermediate position of the wire portion between the connectors, a wire-side surge reducing section provided in the wire portion, a connector-side surge reducing section provided in each of the connectors, and a middle portion-side surge reducing section provided in the middle portion.

Wire harness

Provided is a structure in which: after a harness-side connector including a harness-side female terminal and a unit-side connector including a unit-side female terminal are caused to face each other at a position of a through hole in a floor panel, the harness-side connector and the unit-side connector are connected by a male terminal of a male connection member. In more detail, provided is a structure in which the male terminal of the male connection member is inserted through a connection-use penetrating part of the unit-side female terminal to electrically connect two female terminals, that is, the harness-side female terminal and the unit-side female terminal, to each other. Thus, a connector connection structure that does not cause the terminals to deform can be provided, and a connector connection structure that can also enhance ease of assembly and enhance ease of maintenance as a consequence can be provided.

Connector connection structure

Each terminal has a connection portion to be connected to a portion of a corresponding one of the electric wires from which an insulation coating is stripped off such that a core wire is exposed, and an extension portion extending from the connection portion and to be connected to a terminal member of a counterpart connection device. The extension portions are each formed to have a cross section of an arc shape and are arranged such that the cross sections are arranged in a substantially circular manner and such that the extension portions are spaced from each other in a circumferential direction.
