Abstract: A dry-mate connector has nipples on the front or mating side of the electrical conductors on both the plug and receptacle units which cooperate with an elastomeric seal on the mating end of one of the units to provide an individual seal around each electrical circuit in the mated condition. In a hybrid version of the connector, an optical contact assembly is provided in each unit which has a multi-fiber ferrule at the mating end of the assembly, allowing a high contact density to be achieved in a relatively small space.

Abstract: A connector, such as for harsh environments, may include first and second connector portions being movable between unmated and mated positions. The first connector portion may include a first base, at least one male contact carried by the first base and extending outwardly therefrom, and a first shell carried by the first base and surrounding the at least one male contact. The second connector portion may include a second base, at least one female contact carried by the second base and extending outwardly therefrom, and a bladder carried by the second base and surrounding the at least one female contact. The second connector portion may further include an end cap having at least one passageway therein for retaining and aligning end portions of the bladder opposite the second base, and a second shell carried by the second base and surrounding the bladder and the end cap. The end cap and adjacent portions of the second shell may include respective mating portions to provide a snap fit engagement therebetween.

Abstract: A connector may include first and second connector portions movable between unmated and mated positions; first and second bladders carried by respective connector portions, and each having an end movable between a closed position and an open position; and an interlocking assembly including first and second portions carried by respective connector portions and being movable between a released position, permitting opposing ends of the bladders to move apart, and an interlocked position, holding the opposing ends of the bladders together. The interlocking assembly may hold the opposing ends of the bladders together as the opposing ends of the bladders move from the closed position to the open position and/or as the opposing ends of the bladders move from the open position to the closed position. Also, the interlocking assembly may provide a positive drawback between its first and second portions during movement from the interlocked position to the released position.

The elastomeric inner seal may have at least one nipple passageway for receiving and defining a seal with the at least one nipple, and at least one cable member passageway in communication with the at least one nipple passageway for receiving and defining a seal with the at least one cable member. The elastomeric outer seal may have opposing first and second open ends, with the first open end for engaging and defining a seal with the base.

Abstract: A dry mate connector has first and second connector modules, and a coupling member or slidable retention sleeve mounted on the first module. Resilient latch formations are provided for releasably securing the modules together in a mated position. The modules each have at least one contact for communication with the contact of the other module within a closed, locked and sealed contact chamber formed by the coupling member and modules in the mated position. Mating, locking and sealing are achieved by movement of the parts in a single, mating direction, and the modules are separated by motion in a single direction opposite to the mating direction, using the same two grip surfaces for both mating and unmating. A collapsible fluid-filled hose with bellows portions may extend between a first connector module and a second connector module in an optical cable arrangement using the dry mate connector.

Abstract: A live animal trap includes only two basic parts, an elongate hollow tube and a pivot support stand on which the tube is pivotally mounted. The tube has a first, closed end for holding bait and a second, open end. The tube is pivotally mounted on the stand for rotation about a horizontal pivot axis transverse to the tube axis. The pivot axis is located closer to the first end of the tube than the second end. When the stand is placed on a support surface, the longer end of the tube will be slightly heavier, so that the second end of the tube will pivot downwardly into a set position in which the tube is inclined upwardly with the second end contacting the support surface. An animal can enter the open second end of the tube and move towards the bait. When the animal passes the pivot axis, the first end of the tube becomes heavier and pivots downwardly, moving the second end upwardly, until the tube reaches a vertical, actuated position with the animal trapped in the first, bottom end of the tube.

Abstract: An underwater connector has mateable plug and receptacle units each containing a member having an internal chamber enclosing a contact element when the units are unmated. The members each have a resilient forward end portion with an opening communicating with the chamber, and a forward end face in sealing engagement with the corresponding end face of the other member to provide a seal when the units are mated. An actuator in each unit compresses the forward end portion of each member to close and seal the opening, and the arrangement is such that the forward end portions move away from the actuators and open as the units are mated, to permit one contact element to pass into the member of the other unit for connection to the other contact element. The forward end portions of the members are self-sealing in both the mated and unmated condition, requiring no additional seal elements.
