Test Probe for Electric Conductor Boards

The test probe shown in the figure, is particularly suitable for measuring electric signals on conductor bars carrying electronic components at high- packing densities.

Mask aperture board 2 with holes 8 corresponding to the raster of the conductors is arranged above conductor board 1. Probe support block 3 comprises a narrow arm 4 embracing probe guide bush 5 on its free end. Within bush 5, tapered thin probe pin 6 is telescopically movable against the tension of helical spring 7. Bush 5 is closed on its upper end and constricted on its lower end to prevent nail-shaped probe pin 6 from dropping out.

Block 3 is held in aperture board 2 by two guide pins 11, 12 forming the ends of expanding spring 14. The leg of spring 13 forming guide pin 11 is stationarily arranged in block 3, whereas the leg forming guide pin 12 is guided in slot 14 of block 3, being movable in the direction of the other leg against the tension of leaf spring 15 also provided in block 3. This permits adapting the spacing of guide pins 1l, 12 to that of the apertures in board 2 at the measuring point.

Pins 11, 12 are pressed together sufficiently close and inserted into two selected holes of board 2, whore they retain block 3 under the influence of springs 13, 15. Sprung probe pin 6 supports itself on conductors 16 carrying the signals to be measured. Via connectors, not shown, the measuring values are scanned on the upper end of bush 5.
