Definitions

  • the present invention relates an electric connector, which is connectable to any one of a plurality of counter-connectors having different configurations from each other.
  • connection terminals for car audio systems are different from each other, depending upon the type of a car in a region. It may be necessary to attach a specific connector, which is exclusively used for a certain type of a car, when selling a speaker system, for example.
  • An object of the present invention is therefore to provide an electric connector, which is commonly connectable to any one of a plurality of counter-connectors, which have different configurations from each other.
  • an electric connector according to the first aspect of the present invention which is connectable to a counter-connector, comprises:
  • connection portion has a shape serving as said structure, said shape being obtained by combining the configurations of said plurality of counter-connectors with each other so that said connection portion is connectable to said any one of said plurality of counter-connectors in a proper positional relationship of said connection portion with said any one of said plurality of counter-connectors, while said connection portion comes into contact with said any one of said plurality of counter-connectors to prevent said connection portion from being connected to said any one of said plurality of counter-connectors in a improper positional relationship thereof.
  • said electric connector serves as a female connector, into which any one of said plurality of counter-connectors serving as male connectors is to be inserted; and said main body has an insertion opening with an inner peripheral portion serving as said connection portion, into which said any one of said male connectors is to be inserted, said shape of said insertion opening being obtained by combining outer configurations of said male connectors with each other.
  • said electric connector serves as a male connector, which is to be inserted into any one of said plurality of counter-connectors serving as female connectors each provided with insertion openings; and said main body has an outer peripheral portion serving as said connection portion, which is to be inserted into said any one of said female connectors, said shape of said outer peripheral surface being obtained by combining shapes of said insertion openings of said female connectors with each other.
  • the electric connector is connectable to any one of the plurality of counter-connectors, which have different configurations from each other, thus making it possible to eliminate the need for providing a plurality of connectors corresponding to the counter-connectors.
  • the connection portion of the main body of the electric connector has the structure for coming into contact with any one of the counter-connectors in case where any one of them is placed in a position other than the normal position. It is therefore possible to prevent the electric connector from being wrongly connected to the counter-connector.
  • said main body may have a guide means for guiding said any one of said plurality of counter-connectors. According to the fifth aspect of the present invention, it is possible to easily connect the electric connector to the counter-connector.
  • said main body may have a separation preventing means for preventing said any one of said plurality of counter-connectors from being removed from said main body. According to the sixth aspect of the present invention, it is possible to prevent the counter-connector from being erroneously removed from the electric connector.
