Pressurized Electrical Contact Block Assembly

This block has longitudinally slidable, electrical contact pins. The latter are maintained free of grit, dust, etc., by an outward flow of air.

Block 10 with slidable spring-biased contact pins 12 has manifold 14 connected to a source of air under pressure. Pressurized air flowing into manifold 14 escapes through the clearance spaces about pins 12, both through the top and the bottom of block 10. The constant outward flow of air around pins 12 prevents excessive wear and binding of the pins.

Pressurized block 10 is particularly adapted for use in environments containing abrasive and dust. Pins 12 are normally used to make electrical contact between a test or monitoring device and a substrate having electrical components arranged in a circuit mounted on it.
