Pivotally mounted printed circuit board holder

Claim 2

For use in an electronic data processing device having a base, a holder for printed circuit boards comprising: first and second support members extending upwardly from the base, each of said support members having a stop member and an inwardly extending stud, said studs being aligned along a common axis; a generally rectangular receptacle having opposed end walls, opposed side walls and a bottom wall, each of said sidewalls further including a recessed panel parallel to but displaced outwardly from the remainder of the side wall and having an opening therein for receiving one of the inwardly extending studs on the support members, said receptacle being pivotable from a normal position in which the bottom wall is approximately parallel to but spaced above the base to a service position delimited by the stop members on said support members, the bottom wall being approximately perpendicular to the base in the service position; and latching means for releasably holding said receptacle in the normal position.

Claim 3

A holder as defined in claim 1 wherein each of the side wall openings is defined by a first semicircular indentation in the lower edge of the recessed panel and a second, oppositely-oriented semicircular indentation in the side wall at the lower edge of the recess, said indentations forming a circular opening for receiving the stud on the associated support member without allowing the stud to extend inwardly substantially beyond the inner surface of the receptacle side wall.

Claim 4

A holder as defined in claim 2 wherein said receptacle is an integral, molded structure.

Claim 5

A holder as defined in claim 3 in further combination with: multiple pin connector boards for providing an electrical interface between printed circuit boards carried by said holder and cable-terminating connectors associated with the data processing device; and means for retaining said connector boards at the bottom wall of said receptacle.

Claim 6

A holder as defined in claim 4 wherein said retaining means comprises: at least one stiffener plate having openings therethrough for the pins on said multiple pin connector boards; and latching means for securing each said stiffener plate to said receptacle at the bottom wall thereof, said latching means comprising a plurality of bendable latching arms, each extending beyond the bottom wall of said receptacle at the periphery thereof and each having an inwardly-extending shoulder parallel to the bottom wall.

Claim 7

A holder as defined in claim 4 wherein said holder latching means comprises: at least one latching post extending upward from the device base, each said latching post having a shoulder extending parallel to the base; at least one latching arm extending outward from the bottom wall of said receptacle, each said latching arm bearing against the underside of a latching post projection in an unbiased state to prevent upward pivotal movement of the receptacle, each said arm and post being relatively movable to release the receptacle from the latched condition.

Claim 8

For use in an electronic data processing device having a base, a holder for printed circuit boards comprising: first and second support members extending upwardly from the base, each of said support members having a stop member; a generally rectangular receptacle having opposed end walls, opposed side walls and a bottom wall, said receptacle being supported by said support members for pivotal movement about an axis between said members from a normal position in which the bottom wall is approximately parallel to but spaced above the base to a service position in which the bottom wall is approximately perpendicular to the base, said receptacle being prevented from movement beyond the service position by said stop members; latching means for releasably holding said receptacle in the normal position; multiple pin connector boards for providing an electrical interface between printed circuit boards carried by said holder and cable-terminating connectors associated with the data processing device; and means for retaining the connector boards at the bottom wall of said receptacle, said retaining means further comprising at least one stiffener plate having openings therethrough for the pins on said multiple pin connector boards, and latching means for securing each said stiffener plate to said receptacle at the bottom wall thereof, said latching means comprising a plurality of bendable latching arms, each extending beyond the bottom wall of said receptacle at the periphery thereof and each having an inwardly-extending shoulder parallel to the bottom wall.

Claim 9

For use in an electronic data processing device having a base, a holder for printed circuit boards comprising: first and second support members extending upwardly from the base, each of said support members having a stop member; a generally rectangular receptacle having opposed end walls, opposed side walls and a bottom wall, said receptacle being supported by said support members for pivotal movement about an axis between said members from a normal position in which the bottom wall is approximately parallel to but spaced above the base to a service position in which the bottom wall is approximately perpendicular to the base, said receptacle being prevented from movement beyond the service position by said stop members; latching means for releasably holding said receptacle in the normal position; multiple pin connector boards for providing an electrical interface between printed circuit boards carried by said holder and cable-terminating connectors associated with the data processing device; and means for retaining the connector boards at the bottom wall of said receptacle, said retaining means further comprising at least one stiffener plate having openings therethrough for the pins on said multiple pin connector boards, and latching means for securing each said stiffener plate to said receptacle at the bottom wall thereof, said latching means comprising a plurality of bendable latching arms, each extending beyond the bottom wall of said receptacle at the periphery thereof and each having an inwardly-extending shoulder parallel to the bottom wall.

Claim 10

A holder as defined in claim 7 wherein said holder latching means comprises: at least one latching post extending upward from the device base, each said latching post having a shoulder extending parallel to the base; at least one latching arm extending outward from the bottom wall of said receptacle, each said latching arm bearing against the underside of a latching post projection in an unbiased state to prevent upward pivotal movement of the receptacle, each said arm and post being relatively movable to release the receptacle from the latched condition.

Claim 11

A holder as defined in claim 8 wherein each said holder latching arm and each said stiffener latching arm is integral with the receptacle from which it extends and said side walls, said end walls and said bottom wall are part of an integral structure.
