Provided is a novel dark-current-circuit interruption structure that can stably maintain the state of engagement of an engaging portion of a conductive component holder with an engaged portion of a case, while reducing the size of the case, and an electrical junction box including the same. A conductive component is formed by a plate metal fitting, a conductive component holder 48 includes elastic projecting pieces and engaging portions that are provided on each of a pair of side walls that are opposingly positioned with a gap between the plate metal fitting and each of the side walls, and the case includes engaged portions with which the engaging portions are to be engaged. When attaching the conductive component holder to the case, the engaging portions and the engaged portions are configured to come into contact with each other to cause the elastic projecting pieces 68 and 76 to elastically deform.

A hard disk data interface pitch converter is disclosed, which comprises: a converting part, comprising converting terminals and contact terminals, the converting terminals comprising metallic conductors having a relatively large interval at one end and a relatively small interval at the other end; a short connection part for connecting any two or more non-adjacent metallic conductors in the contact terminals through metallic conductors; a base with a channel for accommodating the contact terminals and a slot for fixing the short connection part; a cover body cooperating with the base for protecting the converting part and short connection part. An extension part is formed by digging each metallic conductor in the contact terminals, and exactly shields a gap between the contact terminals and channel. The short connection part enables miniaturization of a device. It is possible to prevent adhesives or foreign objects from falling onto contacting ends of the contact terminals.

An assembly includes a first cover, a second cover, a first male insert, a first female insert, a second male insert, a second female insert, and/or a busbar, in some configurations. The second cover may be connected with the first cover. The first male insert may be connected to the first cover. The first female insert may be connected to the second cover and the first male insert. The second male insert may be connected to one of the first cover and the second cover. The second female insert may be connected to the second male insert and the other one of the first cover and the second cover. The busbar may be in contact with the first female insert and the second female insert.

A ground contact connecting member comprises a support portion and a plurality of contacting beams. The support portion extends in a first direction and is adapted to be fixed to an installation portion of a connector housing. The plurality of contacting beams extend from the support portion in a second direction, perpendicular to the first direction. The contacting beams are adapted to contact a plurality of ground contacts arranged in the connector housing in a third direction perpendicular to the first direction and the second direction.

A connector for connecting control conductors provided in conduits also containing power conductors, the connector including a first guide for receiving a first at least one control conductor provided in a first conduit also containing at least one power conductor, a second guide for receiving a second at least one control conductor provided in a second conduit also containing at least one power conductor, at least one jumper for electrically connecting the first at least one control conductor and the second at least one control conductor and a housing for containing the first guide, second guide and the at least one jumper.

A joint connector includes shorting members (30) and a shorting member accommodating portion (50) for holding the shorting members (30). The shorting member holding portion (50) includes clamping portions (52, 54, 56 and 58) capable of clamping the shorting members (30) from both sides in a clamping direction and a clamping/fixing portion for constraining these clamping portions (52, 54, 56 and 58) to each other to fix the clamping portions at clamping positions where the clamping portions clamp the shorting members (30). At least some of the clamping portions are constraining clamping portions including shorting member constraining portions for constraining the shorting members (30) to restrict relative displacements of the shorting members (30) in a terminal projecting direction at the clamping positions.

A connector for connecting control conductors provided in conduits also containing power conductors, the connector including a first guide for receiving a first at least one control conductor provided in a first conduit also containing at least one power conductor, a second guide for receiving a second at least one control conductor provided in a second conduit also containing at least one power conductor, at least one jumper for electrically connecting the first at least one control conductor and the second at least one control conductor and a housing for containing the first guide, second guide and the at least one jumper.

In a connection unit for an electrical device, an electrical device system, and a production method, the connection unit has an electrically insulating receiving part, which includes a first receiving section, a second receiving section, and at least one electrically conductive connection device, in particular a bus bar. The receiving part is arranged to accommodate connection device(s) with the aid of the first and second receiving sections. A connection device is accommodated in the first receiving section, and, for example, no connection devices are accommodated in the second receiving section.

A joint connector 10 is provided with connecting members 21 each including a plurality of terminals 12 and a conductive member, and a plurality of housings. The plurality of housings are stacked along a stacking direction. At least one housing constituting the plurality of housings includes a placing portion, on which the connecting member 21 is placed, and a lid portion for at least partially covering the connecting member 21 placed on the placing portion to hold the connecting member 21 in the housing. A first housing 71 and a second housing 171 are stacked on each other. A first lid portion relating to the first housing 71 and a second lid portion relating to the second housing 171 are provided with a stacked state holding portion.
