  • Patent number: 8535073
    Abstract: The connector matable with a mating connector comprises a housing, a lever and an attached member. The housing has a front end, a rear end and an accommodating portion. The accommodating portion communicates with the front end and the rear end. The accommodating portion has an upper portion, a lower portion and side portions. The side portions are formed on respective opposite ends in a width direction of the accommodating portion so as to couple the upper portion and the lower portion with each other. The lever is configured to mate the connector with the mating connector and accommodated in the accommodating portion so as to be pivotable. The attached member is other than the housing. The attached member is attached to the housing so as to couple the upper portion and the lower portion with each other at a position located between the side portions in the width direction.

  • Patent number: 8469751
    Abstract: A waterproof connector includes a female contact, a housing, and a retainer. The housing includes a first inner wall surface, a second inner wall surface, a first engaging part, and a lance. The female contact includes a pressed surface that is pressed by the lance, and a first engaged part that is formed to protrude in a direction away from the pressed surface. A second engaging part is formed in the housing and a second engaged part that can be engaged with the second engaging part is formed in the female contact so that a second engagement between the housing and the female contact is achieved on a side opposite to the side of a first engagement between the first engaging part and the first engaged part with respect to a central axis of the female contact.

  • Patent number: 7927122
    Abstract: A connector assembly has a first connector and a second connector matable with the first connector. The first connector includes a first contact having a first contact portion and a first housing configured to hold the first contact. The second connector includes a second contact having a second contact portion that is brought into contact with the first contact portion and a second housing configured to hold the second contact. The connector assembly further includes a positioner operable to position the second contact portion in a first direction so that the second contact portion corresponds to the first contact portion when the second connector is moved relative to the first connector along the first direction.

  • Patent number: 7556515
    Abstract: In a connector including a conductive member adapted to be connected to a connection object, the conductive member includes a movable contacting portion to be contacted with the connection object and a position control portion integrally formed with the contacting portion and serving to control a position of the contacting portion. The contact may includes a main body integrally formed with the contacting portion and an elastic portion coupling the position control portion to the main body so that the position control portion is displaceable with respect to the main body. The main body may be integrally formed with the position control portion. The elastic portion may couple the contacting portion to the main body so that the contacting portion is displaceable with respect to the main body.

  • Patent number: 7503786
    Abstract: A connecting member has a slider with rotation shafts and a contact combined with the slider. The contact has contact portions for connection to a connection object and pressing portions connected to the contact portions, respectively. By rotating the slider about the rotation shafts to press the pressing portions, the contact portions are displaced to be connected to the connection object. It may be configured to press the pressing portions by moving the slider in a straight or curved line. Further, it may be configured that the slider presses the pressing portions to thereby displace the contact portions in directions away from the connection object.
