Abstract: A continuity testing device is provided which can reliably detect incomplete-fitting of the retainer of the connector. The continuity testing device includes a connector guide block into which the connector is inserted in a transverse direction and which is fixed above an opening formed on a cover plate of a case of the continuity testing device, a detection plate provided to the connector guide block and arranged above the connector so as to contact with the incompletely-fitted retainer of the connector when moved downward, a detection pin arranged at the detection plate, a continuity testing part arranged to move in the vertical direction toward the connector, a drive mechanism that operates the detection plate to move in the vertical direction in conjunction with the continuity testing part, and a switch that is activated by the detection pin when the detection pin is completely moved down to the switch.

Abstract: A mounting structure for a continuity testing unit is provided in which the plurality of continuity testing units can easily be mounted to or removed from a test board without using the bolt or the intricately-shaped pin, and which improves the efficiency of restoring the mounting arrangement of the continuity testing units. The mounting structure for a continuity testing unit includes a plurality of parallely-arranged rails arranged at a frame, a joint block arranged on the respective rails and a plurality of continuity testing units each including a plate portion and a pin portion arranged at the plate portion. The joint block includes a plurality of holes into which the pin portion is fitted in a disengageable manner. The plurality of holes is arranged in two lines. The plate portion is placed on the joint blocks on the two adjacent rails.

Abstract: There is provided an operation control structure for a continuity test device for performing lock of a connector and actuation of a continuity test part timely, low cost, easily, and surely including a connector attachment part 3, a continuity test part 4 having a probe pin 12, a first cylinder 16 for locking a connector 10 in the connector attachment part, a second cylinder 15 for moving the continuity test part to the connector attachment part, wherein plugs 30 and 54 of the first cylinder and the second cylinder respectively are supplied with the same pressured air, a speed control valve 26 being provided within a plug 30 of the second cylinder 15, a fine hole 28 thinner than a hole 56 in a plug 54 of the first cylinder being provided in the speed control valve, and wherein the continuity test part is actuated by the second cylinder through the fine hole following lock of the connector by the first cylinder.
