Abstract:
1. A card edge connector adapted to receive an electronic substrate, the electronic substrate including a plurality of contact electrodes on a surface of an end portion of the electronic substrate, the plurality of contact electrodes including a first contact electrode and a second contact electrode, the first contact electrode located in front of the second contact electrode in an insertion direction in which the end portion of the electronic substrate is adapted to be inserted into the card edge connector, the card edge connector comprising: a housing defining an substrate insertion hole for receiving the end portion of the electronic substrate; a plurality of harness terminals located in the housing and including a first harness terminal located in a first distance from the surface of the end portion of the electronic substrate in a height direction perpendicular to the surface after insertion of the end portion into the substrate insertion hole, the plurality of harness terminals further including a second harness terminal located in a second distance from the surface of the end portion in the height direction after insertion of the end portion into the substrate insertion hole, the second distance greater than the first distance; a plurality of relay terminals located in the housing, each of the plurality of relay terminals having a first end in contact with a corresponding harness terminal, and a second end in contact with a corresponding contact electrode, to thereby establish the entire electrical connection between the corresponding harness terminal and the corresponding contact electrode when the end portion is inserted into the substrate insertion hole, the plurality of relay terminals including a first relay terminal configured to electrically connect the first harness terminal to one of the first contact electrode and the second contact electrode when the end portion is inserted into the substrate insertion hole, the plurality of relay terminals further including a second relay terminal configured to electrically connect the second harness terminal to the other of the first contact electrode and the second contact electrode when the end portion is inserted into the substrate insertion hole; and a plurality of harnesses, each harness having a third end connected to a corresponding harness terminal and a fourth end exposed outside the housing, the plurality of harnesses including a first harness connected to the first harness terminal and a second harness connected to the second harness terminal.
