Testing system for matching specified pattern of plug pins at plug block - detects reflection from radiated pin tops of group of pins using image receiver to determine faulty equipped blocks

摘要

The longitudinal axis(29) of the image receiver(17) is inclined at an angle, wrt the plane of the pin tops (18) and wrt the vertical on this plane. The radiation source(16) radiates the pin tops at a large angle(19) wrt the image receiver axis(29). The radiation results across a shade edge(26), which shades off the base region(25) of the plug block(14) from the plug pins (12). Several positions(I,II,III) are provided for the image receiver (16) in relation to the pin group being tested. The radiation source and/or the receiver can be swivelled in these positions or arranged fixed to be switched from alternate sides. ADVANTAGE - Quality testing during prodn.. Reliable identification of faulty pin blocks using appts. at lowest possible cost.
