Abstract: A device for resolving axial and angular misalignments between electrical conductors of adjacent sections of a pre-bussed rigid conduit electrical feeder system. The variable phase positioning device includes a flexible housing with an end piece attached to each end. A number of flexible electrical conductors are enclosed within the housing. Each conductor is enclosed in an electrically insulating sheath. A substantially rigid terminal is fixedly attached to each end of each conductor. At each end of the housing the terminals are loosely captivated within a terminal support such that each terminal can rotate freely. The terminal supports are made from an electrically insulating material. A retaining sleeve is loosely received over each terminal support and attached to the end piece in a manner that permits the terminal supports to rotate freely within the retaining sleeve.
Abstract: A retainer system for holding a board (14) with active electrical components in an electrical connector assembly includes a boss (50,66) secured to the housing (48,64,84) of the connector assembly, with the boss having an elongated slot (52,68) open toward the other end of the housing. The slot is sized so that one end of the board is receivable therein with sufficient clearance to allow pivoting motion of the board toward and away from the housing about that one end within the slot. At the other end of the connector assembly housing is a retainer (54,72,82,100). After the one end of the board is inserted into the slot and the board is pivoted toward the housing, the retainer overlies the opposed end of the board.

The construction provides positive electrical contact and long life for the contact elements with complete RF shielding.
Abstract: This invention provides a single type of electrical connector suitable for use with cables containing from one up to the maximum number of electrical conductors that can be accommodated by passages within the connector without impairing the ability of the connector to exclude moisture and other contaminants from the area occupied by junctions between mating pairs of conductors. This is achieved by the combination of a preformed perforated gasket and a layer of penetrable, non-self-healing, non-flowing elastomer that seals all of the passages in the connector not occupied by conductors.
Abstract: A one-piece insulation displacing terminal having a first portion, a second portion, and a connecting portion connecting the first and second portions. The connecting portion is torsional in order to permit the first portion to rotate relative to the second portion. In one embodiment, the first portion has adjacent first and second walls which are arcuately shaped and which have wire receiving openings therein. The wire receiving openings have associated wire receiving slots. The second portion is mounted in an insulating housing of a connector assembly on a post having a post opening therethrough which has a conical reducer for permitting only wires of predetermined gauge to pass therethrough. After the second portion is secured to a base of the insulating housing, a wall portion of a cap may be slidable mounted between the first and second walls of the first portion. The wall portion has an opening therein to permit a wire to pass between wire receiving openings in the first and second walls.
Abstract: A self terminating phone plug having a switch armature disposed between the inner signal carrying shaft and the outer ground shaft wherein the armature is biased to electrically ground the inner shaft except when an actuator carried by the armature and protruding through the outer shaft is urged inward toward the inner shaft, as when the plug is inserted into a jack, in which case the armature disconnects from the outer shaft and ungrounds the inner shaft.
Abstract: A lock eject mechanism for a pair of electrical connectors includes a first housing (210) for a first electrical connector (200); a lock eject unit (220) provided on opposite sides of the first housing; a second housing (110) for a second electrical connector (100); and a lock eject receiver (120) provided on opposite sides of the second housing for receiving the lock eject units for engagement. The lock eject unit includes a pair of lock eject levers (221) pivoted to opposite sides of the first housing and each having a lock portion (223) at its front section and a lock operation portion (222) at its rear section.
Abstract: The invention relates to a connecting device (200) to equip an end of an electric cable (100), including a multilayer sleeve having an axis (202) and having an insulating intermediate layer (204) interposed between two layers suitable for ensuring the guiding of an electric field.According to the invention, only the end or ends (207) of the sleeve designed to cooperate with a cable end are in a state of radial expansion such that they present an inside diameter that is greater than the outside diameter of the corresponding cable end and which will be less than this outside diameter once retraction of the said ends of the sleeve has been brought about.The invention also relates to a process for mounting this device on the cable or cables.
