  • Patent number: 10290982
    Abstract: An electric connector includes a socket connector, a plug connector having a bar shape for connecting an electric circuit, the plug connector capable of insertion into and removed from the socket connector and to be rotatable between unlocked and locked positions about an axis thereof, a pair of detection terminals opposing across the plug connector, and a conductive member for providing electric conduction between the pair of detection terminals in the locked position of the plug connector. The conductive member includes a pair of pressed pieces arranged between the pair of detection terminals and the plug connector, spaced away from the detection terminals in the unlocked position of the plug connector, but pressed by an outer surface of the plug connector in the locked position of the plug connector to bring contact portions thereof into contact with the detection terminals and a coupling piece coupling the pair of pressed pieces.

  • Patent number: 9941649
    Abstract: A connector includes a plurality of contacts each including first and second contact pieces provided with first and second contact portions at distal end sides, respectively, that come into contact with conductor portions of two insertable/removable connection objects when the connection objects are inserted, and a connection portion to be connected and secured to a board. The connector further includes a housing that holds the contacts in an array and includes an insertion opening of a shape that allows insertion of the connection objects and a battery from a same direction, and a terminal is arranged in the housing and spaced apart from the contacts in a width direction of the housing, the terminal including third and fourth contact pieces provided with third and fourth contact portions on distal end sides, respectively, configured to come into contact with the conductor portion of one of the connection objects and the battery.

  • Patent number: 8052464
    Abstract: A connector is provided which includes a plug having a plurality of cables disposed on one side of the plug, and a socket mounted on a base substrate that is used to connect the plug. The plug includes a plate-like member and a flexible substrate fixed to the surroundings of the plate-like member. The plate-like member includes a planar portion approximately parallel to a substrate face of the base substrate, and a bent portion provided on the other side of the plug and extending in a direction approximately perpendicular to the base substrate. The socket includes a mating space which receives the bent portion from a direction approximately perpendicular to the base substrate when the plug and socket are connector-connected.
