The packing holder is made of metal or synthetic resin having shock resistance.

Abstract: A first connector of a pair of connectors fitted has a shell accommodating a second connector of the connectors. By fitting both connectors, female terminals and male terminals are connected to each other. The second connector includes an outer case removably inserted in the shell, an inner case incorporated in the outer case and inserting female terminals therein, a cylindrical body accommodated rotatably in the outer case, and a locking member with an operating lever formed on the cylindrical body. An abutting-on portion in the cylindrical body on the side of the shell has a first magnetic substance. Another abutting-on portion in the shell on the side of the cylindrical body has a second magnetic substance having a polarity opposite to that of the first magnetic substance.

Abstract: Two separate lids are openably provided at two power receiving portions, respectively. A lid fixing unit is provided for sliding movement in a direction of the juxtaposition of the two power receiving portions. The lid fixing unit overlaps both of the two lids to prevent the two lids from being opened when the lid fixing unit is disposed in an intermediate position between the two power receiving portions. The lid fixing unit is movable away from one of the two lids to face the other lid, thereby allowing the opening of the one lid, and the lid fixing unit is movable away from the other lid to face the one lid, thereby allowing the opening of the other lid.
