Patent number: 8025512Abstract: An object fitting/removing drive unit capable of fitting objects to each other, even if there is not enough working space in a fitting/removing direction of one object. Operation members holding cable connectors are accommodated in an inner frame in a manner movable in the fitting/removing direction. The inner frame is movably supported by outer frames along a direction orthogonal to the fitting/removing direction between initial and fitting-completed positions. A coupling member engaged with header connectors is movably supported by the outer frames along a direction orthogonal to the fitting/removing direction. When the inner frame is moved from the initial position to the fitting-completed position by being pressed by the coupling member, the outer frames guide the operation members toward the header connectors to fit the cable connectors and the header connectors to each other. A drive force transferring unit transfers driving force in the orthogonal direction.Type: GrantFiled: June 11, 2009Date of Patent: September 27, 2011Assignees: Japan Aviation Electronics Industry Limited, NEC CorporationInventors: Shigeharu Aoki, Masahiro Yamauchi, Keisuke Nakayama
