Abstract

The drawing shows apparatus for identifying a circuit module 2 from coded holes 3 or the absence of a hole 4 at predetermined sites. conductive pins 5 are mounted in a support 6 in positions corresponding to the sites where a hole may be located. Support 6 is flexible to accommodate warped modules. Compression springs 7 connect the pins to an outer frame 8. The springs urge the pins into the holes in the modules and they provide electrical connections between the pins and terminals 9, shown schematically.

Pin Sensor for Parts Identification

The drawing shows apparatus for identifying a circuit module 2 from coded holes 3 or the absence of a hole 4 at predetermined sites. conductive pins 5 are mounted in a support 6 in positions corresponding to the sites where a hole may be located. Support 6 is flexible to accommodate warped modules. Compression springs 7 connect the pins to an outer frame 8. The springs urge the pins into the holes in the modules and they provide electrical connections between the pins and terminals 9, shown schematically.

Pins located over holes are depressed and make electrical contact with a ground conductor 10 that is located on support 6. The signals at terminals 9 identify the module type. An air pressure fitting 11 is provided in frame 8 for holding the flexible support 6 against the module and for clearing the module of dust.
