Abstract: A high voltage electrical connection includes an electrical receptacle connector and a mating electrical plug connector. The electrical receptacle connector includes a receptacle that is mounted over a hole in the casing and fastened thereto with a plurality of terminated electrical leads that are attached to an internal component of an electrical device inside the casing and threaded through a hole in the casing. The receptacle has a chamber including an inlet at one end that is aligned with the hole in casing and an outlet at the other end. The electrical receptacle connector also includes a terminal holder and a terminal housing, both of which are made of electrical insulation material. The holder retains the plurality of terminals, of the respective leads is inserted into the chamber through the outlet of the receptacle and retained in the chamber. The terminal housing is then inserted into the chamber via the outlet with its flange being disposed in the outlet.

Abstract: A slide contact electrical connector preferably for an oxygen sensor is assembled in such a way as to protect the precious metal surface of multiple contact pads of an edge card 28. The edge card 28 is encased by a ceramic capsule 30. Trailing portions 54 of terminals 20 are laterally inserted into longitudinally extending channels 52 of a core 22 being radially and axially locked in place. The terminals 20 extend forward from the core 22 and are positioned about the trailing end 42 of the edge card 28 from a longitudinal direction. A collar 26 compresses the terminals 20 against the edge card 28 from a lateral direction thereby making the electrical contact. A shield 18 encircles the capsule 30, collar 26, terminals 20 and core 22 thereby protecting the electrical connection integrity. A seal 16 is disposed at a trailing end of the shield 18 penetrated by a plurality of insulated electrical wires 14.

Abstract: An improved method for fixing position of a land-based target site with respect to a reference site in the natural coordinate frame comprising the steps of determining geodetic azimuth between the target site and the reference target using Global Positioning System (GPS) satellites and relative positioning survey techniques; then calculating a relationship using gravity vertical deflections; and then coverting the geodetic azimuth to astronomic azimuth. This method has several advantages over conventional methods of targeting, including speed, the ability to work in all weather conditions, and improved accuracy.

Abstract: An electrical header assembly for a printed circuit board or the like comprises a housing of thermoplastic material having a mating portion and a conductor portion and a row of laterally spaced insert molded blade terminals of stamped sheet metal construction. The blade terminals have tails which are bent vertically in a secondary bending operation to provide vertical legs which are positioned and retained by laterally deflectable walls defining channels at the end of the conductor portion of the housing. The housing has a narrow peripheral groove which is defined by confronting faces of the mating and conductor portions of the housing and which is adapted for mounting the electrical header connector on an apertured panel wall.
