ABSTRACT:
An adapter (13) for a printed circuit board testing device (6), by means of which test contacts, (7) which are located in a grid, may be connected with test points (3), which are located in and/or beyond the grid, on a printed circuit board (2), which is to be tested, the connection being effected by means of adapter pins (14) which extend through first, second and third guide plates (10, 15 and 16), the third guide plate (16) being arranged between the first and second guide plates (10 and 15). The third guide plate (16) is arranged to be shifted square to the first and second guide plates (10 and 15) and guide holes (20) in the third guide plate (16) are provided at all points of the grid. The holes (20) have a diameter which tolerates a limited amount of clearance for steering of the adapter pins (14) in these guide holes (20).
