Abstract

A holding and testing device for electronic modules includes a receptacle depression in a perforate plate that is held by two guide rods. A movable plate carries contact spring pins, fixing pins, and guide pins, and is mounted under the perforate plate for displacement in a vertical direction relative to the perforate plate along the guide rods. Clearances for the contact spring pins and the fixing pins are provided in the perforate plate in the region of the receptacle depression. Horizontally displaceable slides are in the perforate plate at both sides of the receptacle depression and include engagement openings for interactive engagement with the guide pins of the movable plate so that the slides are moved toward one another as the movable plate is lifted. Lateral tongue portions of the slides slide over the electronic module under test to fix the module in proper position in combination with fixing pins, and further lifting motion of the movable plate enables test contacts to make electrical connections with the electronic module under test.
