  • Patent number: 4240032
    Abstract: In testing electronic devices having leads, difficulties are frequently encountered in transporting the devices to a test position and holding them securely while engaging the leads during testing. These difficulties are overcome in devices having an indentation in the body portion by engaging the indentation with a movable carrier pin. This pin pushes the device against a wall. In this position at least one lead of the device is arranged in a specific orientation with respect to the body portion. When the pin (and thereby the device) moves toward the test station, the lead contracts a ramp in its path. As the device continues to move, the lead travels up the ramp thereby pivoting the device into a position at approximately a right angle to the specific orientation upon the device reaching the top of the ramp. The lead is then engaged by a centering element which insures proper alignment for testing. After this alignment, the leads of the device are pressed by a plunger against the wall.
