  • Patent number: 10276983
    Abstract: A connector comprises a holding member, a plurality of terminals and a conductive member. Each of the terminals has a contact portion. The contact portions of the terminals are arranged in two rows along the pitch direction. The conductive member is held by the holding member. The conductive member has a first portion and two second portions. The first portion has a plate-like shape. The first portion has two first engagement portions. Each of the second portions has a second engagement portion. In the perpendicular direction, the second engagement portion has a size different from a size of the first engagement portion. One of the first engagement portion and the second engagement portion is recessed in the mating direction. A remaining one of the first engagement portion and the second engagement portion protrudes in the mating direction and is received in the one of the first engagement portion and the second engagement portion.
