Abstract

An electrical interface arrangement enables a complex circuit board to be connected to an electrical test equipment to verify the correct operation of the circuit board or to identify malfunctions. The interface arrangement makes electrical contact with predetermined points of the circuit board and connects these points to predetermined terminals of the test equipment. Each electrical interface arrangement is likely to be unique to a particular type of circuit board, and it has proved very difficult and time consuming to reliably interconnect the contacts of the electrical interface arrangement--typically 200 to 300 interconnecting leads are required. To facilitate the interconnection process, the interface arrangement is provided with a movable connector which in one position co-operates with the test equipment and which in another position is such that its terminals lie in substantially the same plane as those of the electrical contacts which, in operation, touch the predetermined locations of the circuit board. In the latter position the two sets of terminals can be interconnected very readily using a semi-automatic wiring machine.
