<p>A hand held portable computer (10) is secured to a peripheral computer component or expansion module (12) in a snap-on arrangement which automatically effects engagement of bus connectors (28a, 28b) between the two components. The hand held computer has four openings (22, 24) in its back or under side. Two of the slot-like openings (24) have fittings within them or are so shaped as to receive L-shaped or hook-shaped brackets (32) of the peripheral component (12). The brackets (32) may be inserted in the slot openings (24) when the computer (10) and the expansion module (12) are held obliquely angled with respect to each other. The computer (10) is then swung down until its back or under side engages against the top of the peripheral component (12) whereupon a pair of protruding hook members (32) extending at the top surface of the peripheral component engage the computer and snap into locking engagement in the adjacent slot openings (24). The bus connection is made when the two components are brought together.</p> |
