A connector for elongated members such as wires or cables receives the members into holes in opposite ends of the connector, so that the members are offset radially outward from the central longitudinal axis of the connector on opposite sides of the axis. Portions of the connector housing may be twisted/rotated relative to each other on the axis to connect the members mechanically, and electrically if the members are conductive. The twisting/rotation of the housing portions moves the portions of the elongated members that are inside a hollow interior space of the connector to be against, and then to wrap around, a central, axial element that is on or near the central longitudinal axis of the connector. This causes each member to wrap around or adjacent to coils of the other member, forming a purposely tight and/or tangled knot of coils of both elongated members around the central element.

One aspect of the present disclosure provides a connector holder capable of suppressing interference between a wire harness of an instrument panel and a vehicle body. A connector holder (11) according to one aspect of the present disclosure comprises an engagement part (23), having a projecting shape, that can engage with a cover attachment hole (6) formed in an instrument panel (1). A wire harness (10) comprises a connector holding part (21) for holding a connector (13) of the wire harness (10), and a bolt covering part (22) extending from the connector holding part (21). The bolt covering part (22) is configured to cover a bolt (B) fixed to a vehicle body (2) in a state where the connector holding part (21) is fixed to the vehicle body (2). The engagement part (23) is provided in the bolt covering part (22).

A multipurpose wire connection device includes a base plate, a conductive plate, a wire fixation screw, a fireproof box, a support, and a dustpan-shaped housing. The support is disposed on the base plate. The fireproof box includes a rear panel, a bottom panel, two side panels, and an inserted plate. The wire fixation screw is mounted on the conductive plate. The housing is fixed on the bottom plate by a housing fixing screw. The multipurpose wire connection device prevents sparking and red burning of a ground screw when lightning current passes therein, due to corroded contact in long-term exposure to wind and rain. It avoids fire and explosion accidents. It avoids screw corrosion and facilitates ground resistance measurement. The multipurpose wire connection device can also be used for electrical relay, division, and branching. It prevents fire, explosion, rain intrusion, and rust development. It is easy to disassemble.
