High Density Connector With Sliding Actuator

View page
US Patent:
53340388, Aug 2, 1994
Filed:
Dec 6, 1993
Appl. No.:
8/161991
Inventors:
Ronald V. Davidge - Coral Springs FL
Todd A. McClurg - Boca Raton FL
Jay H. Neer - Boca Raton FL
Richard J. Nelson - Boynton Beach FL
Rocco J. Noschese - Wilton CT
Assignee:
International Business Machines Corp. - Armonk NY
International Classification:
H01R 1362
US Classification:
439267
Abstract:
An electrical connector for removably receiving a daughter card includes a first group of contact springs, which extend in their free, undeflected state into a card-receiving slot, and a second group of contact springs, which are displaced from this slot in their undeflected state. This connector also includes an actuator, which can be moved to engage the second group of contact springs so that they are moved into the card-receiving slot. The actuator can be left in a position in which it is not so engaged when a first type of daughter card is inserted in the connector, with slotted portions of the daughter card passing over surfaces of the actuator. The actuator is moved into this engagement with the insertion of a second type of daughter card as surfaces on the daughter card push on surfaces of the actuator. The actuator also includes means by which it is locked to this second type of daughter card so that it is restored to its unengaged position as the daughter card is withdrawn from the connector. In an alternative embodiment, the engagement of the actuator is not controlled by the surfaces of the daughter card, but rather by manual movement of an engagement lever.

Assignee:
International Business Machines Corp. - Armonk NY
International Classification:
H01R 1362
US Classification:
439304
Abstract:
Cover assemblies, capable of being locked and unlocked by means of a key, are configured to be placed over the connectors at each end of an external computer system cable.

Ronald P. Sidor - Stratford CT
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H01R 2370
US Classification:
439 60
Abstract:
An electronic connector is configured to removably receive either a circuit card of a first type, having one row of contacts per side, on an insertion tab adjacent to an insertion edge, or a circuit card of a second type, having two rows of contacts per side. Two rows of spring contacts are provided for this purpose on each side of a central card-receiving slot. Interposing means are also provided to prevent contact between a daughter card of the first type fully inserted in this slot and one of these rows on each side. These interposing means may consist of a slotted interposer structure slid over a portion of the insertion tab of the card, or alternately of a pair of pivotable interposers mounted along the length of the connector, to be pivoted by sections of daughter cards of the first type so that vanes extending from these interposers will push these springs away from the card. An electronic device, such as a connector of this type, includes solder tails for attachment within holes of a mother board, aligned in several parallel rows. Individual solder tails in each row are displaced by a first distance.
