Abstract : A high contact density circular connector capable of receiving, indexing, and fixedly holding a multi-element probe tip used to test the quality of tapered fastener holes. The outer surface of the probe tip has a multiplicity of conductive segments, which are covered by a thin layer of insulation at the end to be inserted into the holes being inspected. When the probe tip is inserted into a hole, capacitors are formed between the conductive segments on the probe tip and the metallic walls of the hole, which can be measured for value and correlated in a computer to disclose hole characteristics such as size, shape, and smoothness. The circular connector is the means by which probe measurements are transferred from the tip into a coaxial cable, for transmission to the electronic processor without molesting the minute capacitance measurements. The connector receives the probe tip, and by means of a key, indexes the angular orientation of the cylindrically shaped probe tip to mate appropriate conductive segments on the probe tip with the connector clips within the body of the circular connector. With the probe tip in place, a compression ring encircling the connector is rotated to draw the connector body and contacts tightly about the probe tip, thereby insuring effective electrical mating and fixed retention of the probe tip in the connector.
