Abstract

The appliance supports components during testing and includes a hard, molded plastic base carrier 1 and a plurality of subcarriers 2 mounted on it. Each subcarrier 2 includes an inwardly lipped nest 3 for insertion of a module 4 to be tested. Subcarriers 2 are also slidably mounted on upstanding slide pins 5 provided on the top surface of carrier 1. Included in subcarriers 2 are longitudinal recesses 6 in their lateral edges for engagement with bottom flange 10 of recesses 8 provided in side supports 9 of elevating structure 30. The upper flange 7 of recess 8 overrides the top of the side-recessed portions of subcarriers 2 during engagement between the two at a test station.

Test Appliance

The appliance supports components during testing and includes a hard, molded plastic base carrier 1 and a plurality of subcarriers 2 mounted on it. Each subcarrier 2 includes an inwardly lipped nest 3 for insertion of a module 4 to be tested. Subcarriers 2 are also slidably mounted on upstanding slide pins 5 provided on the top surface of carrier 1. Included in subcarriers 2 are longitudinal recesses 6 in their lateral edges for engagement with bottom flange 10 of recesses 8 provided in side supports 9 of elevating structure 30. The upper flange 7 of recess 8 overrides the top of the side-recessed portions of subcarriers 2 during engagement between the two at a test station.

Supports 9 are mounted on platform 10 by standards 11 of a height to provide suitable clearance about the test appliance. Vertically reciprocable ram 12, secured to platform 10, raises subcarriers 2, by side portions 9, and concurrently elevates a mounted module 4 for insertion of its pins 13 into overhead socket 14 of test can 15. As subcarriers approach can 15 for insertion of module 4 the socket 14, guide pins 20, on can 15, engage into guide bores 21 on subcarrier 2 for accurate positioning of module 4 relative to socket 14.

The carrier is incrementally indexed by pinion gear 16 meshing with rack 17 provided on the bottom surface of carrier 1. In this manner successive ones, of a plurality of subcarriers 2 mounted on a single base carrier 11, are brought into engagement wit...
