  • Patent number: 5552240
    Abstract: A battery (8) powered electrical device (10) is disclosed having an outer case and a battery holder (12) that is received within an opening in the outer case. The device (10) includes an electrical component (24) that is electrically interconnected to the battery (8). A latching mechanism is provided for latching the holder (12) within the case. A pair of resilient arms (102, 104) having projections (106) are cantilevered from the case on opposite sides of the opening and extend into the opening. When the holder (12) is inserted into the opening the projections (106) engage depressions (74, 76) in the sides of the holder (12) to effect the latching while minimizing the outer peripheral size of the holder (12).

  • Patent number: 5510959
    Abstract: This invention is directed to an improved PCMCIA frame kit for receiving a planar electronic device, such as a printed circuit board or memory card, for electrical engagement with a complementary device in electronic equipment, such as a computer. The kit comprises a pair of matable, cover members to provide shielding to the planar electronic device, and that each cover member is integrally molded to a dielectric frame upon which the planar electronic device is seated. The improvement hereof lies in the provision of each frame including a dielectric extension intermatable with one another to define a cavity for receiving a portion of the planar electronic device. By this arrangement the planar electronic device may be provided with an antenna for the transmission of signals through the dielectric extension. Optionally, the cover members and extensions may be essentially identical in construction having appropriate means about the periphery thereof, for intermatability.

  • Patent number: 5435744
    Abstract: This invention is directed to an electrical cable connector of the type for mating with and latchably engaging a complementary connector. The connector typically includes a dielectric housing containing an array of electrical contacts for electrical engagement with respective contacts in a complementary connector. The connector further comprises a pair of unitary metal shielding members stamped and formed from a metal sheet blank, where a first of the shielding members includes a pair of reversely bent latching arms extending from a mating end toward a cable receiving end, and a pair of hermaphroditic cover members formed of a dielectric material adapted to interfit together about the electrical connector in sliding engagement therewith, and movable from a first position to a second position to effect unmating of said electrical connector from the header assembly. Each cover member includes a latching arm receiving recess, and a flexible arm engageable with a complementary recess in the opposing cover member.
