Embodiment Construction

[0024] figure 1 A partial cross-sectional view of the adapter of the present invention is shown. The adapter 1 of the present invention has four guide plates 2 to 5, which are substantially parallel to each other. Each guide plate 2 to 5 is provided with a guide hole 6 . A test pin 7 is placed in the guide hole 6 , and the test pin extends from a test pin 8 of a main grid 9 to a test point 10 of a printed circuit board 11 to be tested.

[0025] The test pins 8 are parallel to each other and are in contact with the test contacts of the main grid of the printed circuit board testing device. The test pins are thus provided in the grid of the main grid test contacts. The test pin 8 is elastic.

[0026] The guide plate 2 adjacent to the main grid 9 is called the substrate 2 . The guide plate 5 adjacent to the printed circuit board 11 to be tested is called a contact plate 5 .

[0027] The guide holes 6 of the substrate 2 are arranged in the same pattern as the test contacts 8...

Abstract

The adapter for testing circuit boards comprises testing needles (7) and guide plates (2, 3, 4, 5) which form two units (12, 16) consisting of one or several guide plates. The guide holes (6) of all guide plates of each unit are arranged in the same pattern. At least one of the two units are laterally movable relative to one another in such a way that the respective guide holes for a given testing needle can be aligned in pairs. Also claimed is a testing needle (7). Such a needle is provided with at least one hinge section.

Description

technical field [0001] The invention relates to a printed circuit board test adapter and a test needle. Background technique [0002] Patent EP 149 767 B2 once proposed a connector for a printed circuit board tester, which can make the test contacts in the grid of the test device pass through the connector pins to the test contacts outside the grid or the printed circuit board network to be tested. Test point connections within or outside the cell. The joining tool has three guide plates, which are parallel to each other and have a fixed distance. The guide plate is provided with a guide hole, and an adapter needle can be inserted into the guide hole. The setting of the guide hole on the guide plate makes the connector pins straightly inserted from the test contacts to the test points of the printed circuit board. Each adapter needle can be perpendicular to the guide plate, and can also be inclined to the guide plate, so that the test contacts of different configurations ...
