Abstract: Separating connector assemblies of a separable connector system. The separable connector assemblies include one or more pairs of connectors configured to engage and disengage one another in electrical connection and disconnection operations, respectively.

Abstract: An electrical shuttle connector is capable of being used in high electrical power applications without incurring contact erosion upon the primary electrical contact location with a male pin. A shuttle which receives the male pin is contained by and slides axially within a receptacle of the connector between a mated position and a disengaged position and through an unmated position. An arcing contact face of the receptacle and a leading arcing contact surface of the shuttle incurs any high voltage electrical arcing when mating or un-mating the electrical shuttle connector. As such, when un-mating, the arcing contact face and the leading arcing contact surface disconnect prior to the electrical disconnection of the shuttle from the male pin. When mating the connector, the shuttle establishes electrical continuity with the male pin prior to the electrical engagement of the arcing contact face with the leading arcing contact surface.

Abstract: An electrostatic discharge-safe connector comprising mating male and female connectors, that includes an insulated connector pin and a shorting member comprising an electromagnetic interference (EMI) sandwich structure that shorts the connector pin to the body of the connector when the mating portions are unmated. The EMI sandwich structure comprises an EMI gasket material sandwiched between two layers of insulating material. The EMI gasket material has a bulk resistivity of less than 10 ohms per square. When the male connector is inserted into the female connector, the EMI sandwich structure moves away from the conducting portion of the connector pin and rides against the insulating sleeve that surrounds the connector pin. This prevents conduction of electrical charge to the pin from the shell or vice versa. The present connector thus provides protection against electrostatic discharge.

Abstract: An electrical connector (10) has first and second separable contacting electrodes (12, 14) which do not generate an arc on making or breaking. A member (44) interrelates one of the electrodes (14) via a spring-loaded drive cap (24) at ground potential, which member 44 is constructed of a material a wide range of electrical resistance (e.g., insulator to substantial short) inversely response to the magnitude of electric field across the member. On electrode preparation, the drive cap (24) establishes a relative movement of the member (44) with respect to the electrode (14) reducing the member material thickness to such a point that the electric field across the intervening member material reduces the electrical resistance to a desired low level (e.g., short to ground).

Abstract: A high voltage insulated bushing module of the gas operated fault closure type for connection with the probe of a mating insulated elbow module is disclosed. The module includes a snuffer tube adapted to perform as a piston within a piston cylinder cut from a length of drawn aluminum tubing. A connector unit mounted on and carried by the tube is provided to conduct load current in series abutting contact with and between the probe and the cylinder.

Alternatively, the connector unit is adapted for connection to an elongated, replaceable nut connected directly to the threaded stud of a mating bushing well, thereby rendering all load current conductive components of the bushing insert to be readily replaceable.
