Abstract: A method and apparatus for sealing exposed portions of an electrical connector is disclosed. A sealing member is formed directly onto the housing of the electrical connector to seal the exposed portions of the electrical contacts therein. The sealing member engages the housing in a non-adhered relation so as to admit removal of the sealing member from the housing. The sealing member is useful to seal the electrical contact from exposure to a protective coating process.

Abstract: A pass-through terminal arrangement to be mounted on and extended through a mounting opening of a wall of a casing in a mounted position thereof includes a plurality of terminals each of which includes a terminal housing and a current bar having a projecting portion which extends out of the terminal housing and, in the mounted position, through the mounting opening into the interior of the casing. A sealing component is mounted on and surrounds a section of the projecting portion of each of the current bars. The terminal housings are connected in a row to a flange frame of a mounting flange which further includes a pass-through block rigid with the flange frame, at least partially received in the mounting opening in the mounted position, and having a plurality of pass-through openings each for sealingly accommodating at least the section of one of the current bars and the sealing component mounted thereon.

Abstract: A clamping device for securing an object within an aperture of a ring member utilizing a shape memory alloy material. The shape memory alloy material contracts when heated and operates to bias pin members inwardly within a central opening of the ring to thereby secure an object such as a canister placed therein. The shape memory alloy material may be in the form of a strap or wire which is easily heated and provides for a fast clamping and release action of the clamping device.

Abstract: An electrical connector has male and female housing halves each of which has front and rear housing portions. The rear housing portion has an externally threaded front end, a stop shoulder at the rear extent of the threads and a hole to receive a latch pin. The front housing portion has internal threads at the rear end to engage the threads on the rear housing portion and also has an end face with a recess. The latch pin penetrates the rear housing near the stop shoulder and has a nonsymmetrical head. The latch pin can be rotated between a position in which the head protrudes beyond the stop shoulder and a position in which it does not protrude beyond the stop shoulder. When fully threaded together, the recess is aligned with the latch pin which can be rotated to its latching, protruding position to prevent unthreading of the housing portions.

Abstract: A connector for transmission cable has a lower housing and an upper housing securable thereto to be terminated to a prepared end portion of the cable. The conductors are laser welded in slots of the terminals. The contact sections of the terminals reside on respective resilient supports of the lower housing which act in cantilever fashion. A hood section of the upper housing extends over the plurality of contact sections to define a cavity. The connector structure is hermaphroditic in that one connector is matable with another identical connector having a reversed vertical orientation. The respective hoods cooperate to resist the forced cantilever action of the pairs of resilient supports urging each other apart, thus generating contact normal force. The hermaphroditic connectors latch when fully mated.
