    Patent number: 4823079
    Abstract: For testing circuit boards at test points which are located on a raster and the minimum spacing of which is equal to twice the raster dimension, an intermediate adapter (ZA) is used which has a hole (ZAB) with a contact pin (ND2) per test point. Before the intermediate adapter (ZA) is equipped with the contact pins (ND2) the pins are inserted into magazine (MA) which has a cell (MAZ) with contact pins (ND1, ND2, ND3) being provided for each four adjacent raster points. A guiding plate (FP) is arranged between the adapter and the magazine. Guiding holes (FBR) which are arranged on top of the holes (ZAB) of the intermediate adapter are contained in the guiding plate (FP) which are arranged on top of the holes (ZAB) of the intermediate adapter and direct the contact pins (NB2) falling from the magazine (MA) into the holes (ZAB) of the intermediate adapter.
