Abstract
The present invention provides an improved support unit for a test contact device, and a test contact device equipped with this support unit that enables optimized transmission of high-frequency signals while simultaneously ensuring reliable contact with the object being tested. [Solution] The present invention relates to a support unit (19) for a test contact device (20) for reversibly contacting and testing a contact object (30), particularly a board-to-board plug connector, using a high-frequency signal, wherein the support unit (19) comprises an insulating body having a plurality of parallel recesses (19a), particularly slot-shaped recesses, disposed inside, each configured to house and guide a test contact element (10) that transmits a high-frequency signal, each of which is formed between two opposing insulating walls (41) that insulate the test contact element (10).
