Abstract: An electric coupling apparatus for charging a battery. A power supply coupler is adapted to be inserted to a power receiver coupler. The power supply coupler has a primary core and a primary coil located around the primary core. The power receiver coupler has a secondary core and a secondary coil located in the secondary core. The secondary core includes first and second core members. The first core member has a magnetic pole protruding through the secondary coil and yokes extending from the magnetic pole. The second core member has a recess that faces the power supply coupler to conduct air for cooling the power supply coupler.

Abstract: An inductive charger coupling for charging batteries of electric vehicles which includes a paddle having a circuit board comprising a communication circuit for receiving electrical signals regarding the battery charging state, and an antenna formed as a conductive print pattern on the paddle circuit board; the communication circuit converts radio signals received by the antenna into electrical signals; the receptacle receiving the paddle during charging includes a communication circuit and an antenna formed as a conductive print pattern on the receptacle circuit board.

Abstract: An inductive charger coupling for charging a battery. The coupling includes a charging paddle and a charging receptacle. The paddle is connected to an external power source and includes a primary core and a primary coil. The receptacle is connected to the battery and includes a secondary core, a secondary coil and a housing. The housing accommodates the secondary core and the secondary coil. When charging the battery, the paddle is inserted in the receptacle. The housing conforms to the secondary core and the secondary coil and has radiator fins on its outer surface. The housing and the fins reduce the size of the coupling while improving the cooling efficiency.

Abstract: A clip assembly is used to connect a base member, such as a vehicle bumper, to a fitting member, such as an ornamental plate. The base member includes a plurality of projections, and the fitting member includes a plurality of corresponding through holes. The projections of the base member are inserted through the through holes of the fitting member. The fitting member is secured to the base member by means of the projections which are clamped by a plurality of clips. A plurality of holding members retain the clips in position during installation, and are disposed around the through holes.
