ABSTRACT:
An adapter (175) for a printed circuit board testing apparatus. The adapter serves to connect testing contacts located in the grid to testing points, located in and/or out of grid, of a printed circuit board to be tested, through adapter pins (181). The adapter pins (181) are conically tapered at their ends facing the testing points. The adapter (175) has a first guide plate (176), a second guide plate (177) and a third guide plate (178) lying in between. The first guide plate (176) only has holes (180) only located in the grid. The second guide plate (177) has holes (179) located in the grid, as well as holes (179a) located out of grid. In order to guarantee that the testing pins (181), with perpendicular introduction into the guide holes (180) of the first guide plate (176), are inevitably always guided into the corresponding guide holes (179, 179a) of the second guide plate (177), the displacement for holes, located out of grid, in the third guide plate (178) is so chosen n that the conical points of the adapter pins (181) in any case still go home into the corresponding guide hole (182a), located out of grid, of the third guide plate (178).
