ABSTRACT:
A connector terminal examination device includes a frame, an examination head mounted on the frame for linear movement in one and the other directions, a connector holder mounted on the frame at one side of the examination head and adapted to receive a connector inserted from the upper side thereof, and an operator disposed on the frame at the opposite side of the examination head to the connector holder and adapted to drive the examination head towards and away from the connector holder. The examination head has a plurality of probes projected forwardly therefrom. Each of the probes has a front probe portion and a rear probe portion slidably received in a metallic tube and independently biased forwardly such that a predetermined gap is formed between the probe portions when they are in the freed condition. The rear probe portion is electrically insulated from the metallic tube. The front probe portion is adapted to be moved into the metallic tube so as to make electric contact with the rear probe portion when pressed by a corresponding terminal of the connector at the time of the examination.
