PRESETTABLE POLARIZING KEY FOR ELECTRICAL CONNECTORS

摘要

A polarizing or keying system wherein the keyed elements in a mating pair of connectors can be selectively preset in any of a number of positions. The keyed element in one connector is polygonal in external cross-section, so that it can be selectively inserted with its keyway in various rotational positions in a correspondingly shaped polygonal opening in the dielectric body of the connector. The connector can then be mated only with a unit in which the coacting key is correspondingly oriented. The keyed element has a shoulder engaging the dielectric body; when the keyed element is retained by fastening means engaging an outer shell, the dielectric body is in turn retained in the shell by the keyed element.
