    Abstract: The present application is directed to dielectric isolators for use in aircraft fuel systems to control lightning induced current and allow dissipation of electrostatic charge. The dielectric isolators are configured to have a high enough impedance to limit lightning currents to low levels, but low enough impedance to allow electrostatic charge to dissipate without allowing buildup. Although the dielectric isolators may develop a potential difference across the dielectric length due to the effects of lightning currents and its inherent impedance, they are configured to withstand these induced voltages without dielectric breakdown or performance degradation. In one embodiment, the dielectric isolator includes a tube constructed of a composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes, and a pair of couplings attached to opposing ends of the tube.

    Abstract: Method for preventing solder from rising to a portion of an electric contact when the electric contact is being soldered to a copper foil so as to extend therefrom. The portion is plated with a noble metal and adapted to contact a mating object. Cooling means is brought into contact with at least the portion of the electric contact adapted to contact the mating object, and connection portion between the electric contact and the copper foil is heated by heating means. The rising of solder can be prevented and the electric contacts thus obtained are superior in mechanical property (sufficient bonding strength), electrical property (conductive property and low contact resistance), resistance to environmental conditions (impediment to oxidization), and physical property (limitation of rise of solder due to capillary action).

In a preferred method for forming an electrical cable connector, such as a loadbreak power cable elbow connector, having a voltage detection test point, an insulative shield is first molded from a thermoplastic and a conductive voltage detection test point terminal is inserted within the plastic insulative shield. An outer shield is then molded from a conductive material.

  • Patent number: 6811418
    Abstract: An electrical connector may include a connector body having a passageway therethrough with a first end for receiving an electrical bushing insert including a shoulder, and a second end for receiving an electrical conductor. The connector body may have an outer end portion adjacent the first end of the passageway with a flared shape. The outer end portion may be movable to the flared shape upon abutting a shoulder of the electrical bushing insert. The outer end portion may have a radius of curvature so that it progressively curls to the flared shape upon abutting the shoulder of electrical bushing insert. To facilitate the flaring and/or to reduce the vacuum, the outer end portion may have a series of slits therein. The outer end portion may be formed to initially have the flared shape even when spaced from the shoulder of the electrical bushing insert.

  • Patent number: 6746258
    Abstract: One of male and female connectors, which are to be fitted together, is provided with a high-speed connector-disengaging unit for increasing the connector-disengaging speed, utilizing a resilient force produced by a resilient deformation. More specifically, one of the male and female connectors, which are to be fitted together, includes a connector housing, a slider for sliding relative to the connector housing 6 in a connector disengaging direction during a connector disengaging operation, and a coil spring (resilient member) which is interposed between the connector housing and the slider, and is resiliently deformed to produce the resilient force when the slider is slid.

  • Patent number: 6537092
    Abstract: Disclosed is a connector having a terminal which is rendered into an electrically connectable state with a counterpart terminal by engaging with the counterpart terminal; a housing for accommodating the terminal therein; and an arc suppressive member which is provided at such a position as to be electrically connectable to the terminal and rendered into contact with the counterpart terminal when the terminal is being disengaged from the counterpart terminal so as to keep on electrically connecting the terminal and the counterpart terminal. The arc suppressive member has such a construction that an amount of discharged arc when the arc suppressive member is detached from the counterpart terminal is smaller than an amount of discharged arc when the terminal is disengaged from the counterpart terminal. With this arrangement, arc discharge at the disengagement of the terminals is suppressed.

  • Patent number: 6468097
    Abstract: A connector is provided with grounding contacts electrically connected to the host device's ground. The grounding contacts are positioned in the insertion path of a plug that is connected to a cable. The grounding contacts momentarily electrically contact the electrical contacts on the plug to discharge electrostatic charges in the cable to ground. A jack behind the grounding contacts in the housing receives the inserted plug. The jack includes jack contacts that are intended for making electrical contact with the plug contacts when the plug is fully inserted. Electrical connection between the plug contacts and the grounding contacts established as the plug is first inserted in the connector is broken prior to the electrical connection between the plug contacts and the jack contacts being established.

  • Patent number: 5703762
    Abstract: An arrangement for connection of wiring backplanes and module circuit boards wherein individual contact passages arranged in a housing are surrounded by electrically conductive shielding plates that are connected to contactings that carry shield potential. They are attached in the intermediate grid both at the backplane side as well as at the assembly side, and are charged with a corresponding potential. In order to create a connector arrangement for extremely high transmission frequencies and good transmission properties, terminal ends of spring elements of the sheet metal shielding compartment and terminal ends of the spring elements of shielding plates of the contact passages abut with a contacting layer of precious metal at the backplane side. Both the spring elements of the shielding plates arranged perpendicular to the wiring backplane as well as the spring elements of the shielding compartment proceeding perpendicular to the wiring backplane are corrugated.
