  • Patent number: 10931065
    Abstract: A connector includes a connector main body having a plate-shaped conductor, conductive contacts, and a housing holding the plate-shaped conductor and the conductive contacts so as to remain insulated from each other and a metallic casing forming an exterior of a pen-type electronic device and having a through hole configured such that a mating connector is insertable. The conductive contacts form parts of an electric circuit different from the plate-shaped conductor in the pen-type electronic device. An end portion of the plate-shaped conductor is fixed to an inner wall of the casing forming the through hole such that a distal end portion of the connector main body electrically connected to the mating connector is located in the through hole.

  • Publication number: 20200161813
    Abstract: A connector is provided with a connector main body having conductive contacts and a housing holding the conductive contacts. The conductive contacts are exposed from the housing so as to be electrically connectable to a mating connector in a distal end portion of the connector main body and are exposed from the housing so as to be electrically connectable to a substrate in a rear end portion of the connector main body. The housing has positioning portions positioning the connector main body and the substrate relative to each other. The positioning portions are located closer to a center line of the connector main body than the conductive contacts when the connector main body is viewed in plan. The center line extends along a direction from the distal end portion of the connector main body toward the rear end portion.

  • Patent number: 10230185
    Abstract: A connector device includes a first connector and a second connector. A first regulating member attached to the first insulating housing of the first connector and a second regulating member attached to the second insulating housing of the second connector include projecting portions, respectively. A first projecting portion of either one of the first and second regulating members provides a second projecting portion of the other regulating member with a first elastic force acting in a first direction in which the first and second insulating housings separate from each other. Additionally, the first projecting portion provides the second projecting portion with a second elastic force acting in a second direction in which the first and second insulating housings move toward each other. The regulating members also form latch members that act to separate the connectors towards a placed or initial state (e.g., FIGS.

  • Patent number: 9601849
    Abstract: A smooth mating operation is enabled by a simple configuration in a state in which electric connectors are easily and reliably positioned. A plug-side mating guide member made of metal projecting to an outer side from a wiring substrate is provided with guide surfaces, which contact part of a counterpart connector and slide so as to carry out positioning of a mating operation. Apart from which the plug-side mating guide member projects from the wiring substrate is directly or indirectly checked visually. As a result, the mating operation can be carried out while approximating the mutual mating positional relation of both of the electric connectors, and the mating positional relation is regulated to a predetermined state by guiding actions of the guide surfaces of the plug-side mating guide member so that the mutual mating operation of the electric connectors is easily and precisely carried out.
