Abstract:
1. Closure mechanism for pressure test chambers for testing electronic components, ICs, under specific pressure conditions, the pressure test chamber having first and second cavity members which can be brought into a converged position in which they enclose a cavity in a tight manner, comprising: a plurality of pivoting jaws which can be pivoted between a closed position and an open position, spacer members movable into a gap between the pivoting jaws and the first cavity member when the first and second cavity members are in the converged position, the spacer members being movable both relative to the plurality of pivoting jaws and relative to the cavity members when the cavity members are in the converged position, a locking arrangement structured to move the spacer members, at least a part of the pivoting jaws having at least one lifting device structured to advance towards the first cavity member by the pivoting jaws so as to press said first cavity member against the second cavity member by the lifting devices in the closed position of the pivoting jaws, at least a part of the pivoting jaws having at least one locking arrangement structured to move at least one of the spacer members into the gap between the pivoting jaws and the pressed first cavity member in such a way that the pressed first cavity member remains in the converged position even when the lifting device has been retracted, wherein the locking arrangement is configured to insert the one of the spacer members perpendicular to the pressing direction into the gap between the pivoting jaw and the first cavity member.
