Abstract
An electrical connector for establishing an interconnection between the contact pads of a printed circuit board device under test (DUT) and an electrical device. The connector includes a flexible circuit carrying the interconnect between the DUT and pcb, which is moved into position by the inflation of a bladder that changes its form to press the contacts on the flexible circuit onto the contact positions of the DUT. The bladder is constrained to minimize its expansion. The flexible circuit is not constrained except at the point it is mated with the circuit board of the equipment driving the DUT. The path of the flexible circuit is shaped by fixed formers and terminates at the bladder. This avoids impinging on the DUT area outwith the contact zone. The connector includes variants which have a lock to secure the DUT in place and sensors to determine when the DUT is fully inserted.
