Patent number: 5836775Abstract: A connector apparatus for a card-like data processing medium comprises a frame (12) having opposing side walls (16a, 16b) that define a storage space (24a, 24b) of the connector apparatus. One end of the frame (12) defines an insertion inlet (22) for inserting a card-like data processing medium (30) in the storage space. A header containing a terminal array (32) is coupled to the end of the frame opposite the insertion inlet (22). An ejection mechanism (40a, 40b) is provided for ejecting the card-like data processing medium (30) from the storage space by manual operation of a push rod (48) that is coupled to the ejection mechanism (40). Means responsive to a control signal are provided for automatically decoupling the push rod (48) from the ejection mechanism to desable the ejection mechanism.Type: GrantFiled: October 28, 1996Date of Patent: November 17, 1998Assignee: Berg Tehnology, Inc.Inventors: Naoki Hiyama, Kenji Suzuki, Vincent D.

Patent number: RE37265Abstract: A connector device includes a housing having a slide plate with a handle. By the manual operation of the handle, the slide plate is moved by a disengageable link mechanism along the length of the housing. When a data storage medium is fully inserted in the connector device and the handle is in a first position, the link mechanism is disengaged. The link mechanism becomes engaged, and thereby operable to move the slide plate, only after the handle is moved from the first position to an extended position. In this manner, inadvertent ejection of the data storage medium is prevented.Type: GrantFiled: March 19, 1998Date of Patent: July 3, 2001Assignee: BERG Technology, Inc.Inventor: Nai Hock Lwee
