Patent number: 7997917Abstract: An environmentally sealed electrical connector comprises a plug connector and a complimentary socket connector. The plug connector includes a plug body, a plug shell, a plug boot, a backshell and an interfacial seal. The socket connector includes a socket body, a socket shell, a socket boot and a backshell. The plug boot and the socket boot each have a plurality of rupturable features, each feature in register with a corresponding aperture through the corresponding connector body. The interfacial seal seats between the plug connector and socket connector when the plug connector is mated to the socket connector. The interfacial seal also has a plurality of rupturable features corresponding to a predetermined contact layout. Thus, when the socket connector is mated with the plug connector, a connector is provided, which prevents contaminants from penetrating the connection.Type: GrantFiled: October 27, 2010Date of Patent: August 16, 2011Assignee: Omni Aerospace, Inc.Inventors: John J. O'Neill, Christopher E. Schaefer

Patent number: 6607393Abstract: A suspension damper system is provided. The damper system includes a damper with a damper rod, a portion of which extends from the proximal end of the damper. The damper rod includes a bore and an electrode disposed within the bore. A fastener for securing the damper rod to a vehicle is also provided. The fastener is disposed over the damper rod and includes a circumferential groove. An electrical connector which includes an electrically conducting terminal is connected to the electrode. The connector includes a lock which mates with the groove in the fastener and includes a ground terminal which is connected to the damper rod.Type: GrantFiled: January 23, 2002Date of Patent: August 19, 2003Assignee: Delphi Technologies, Inc.Inventors: Steven Kent Raypole, Richard M. Fetcenko, Christopher Adrian Margrave, Kathleen D. Murphy, Max F. Viney, Jr., Christopher E. Schaefer

Patent number: 6416340Abstract: A power connector system has a male member, a female member and a contact member. A cable is attached to the male member. The female member has a U-shaped channel. The contact member is U-shaped and is received in the channel. The side walls of the channel have outer edges defining an outer opening to the channel and end edges defining an end opening to the channel. The male member has a single blade which is insertable into the contact member either though the outer opening or through the end opening.Type: GrantFiled: May 4, 2000Date of Patent: July 9, 2002Inventors: Christopher E. Schaefer, John Kountz, Joseph A Finnerty, Robert Stang

Patent number: 6365297Abstract: A battery pack is provided having at least first and second battery modules, and which in one embodiment has ten modules. Each battery module includes a respective first terminal extending from one end of the module and a respective second terminal extending from the other end of the module. The battery pack further includes a conductive interface having a first opening configured to receive the first terminal of the first battery module and a second opening configured to receive the second terminal of the second battery module to thereby provide an electrical series connection. The interface electrically couples the terminals of the two battery modules. The battery pack may further include an electrically non-conductive buss terminal holder configured to receive and position the first and second battery modules and the conductive interface.Type: GrantFiled: December 15, 1999Date of Patent: April 2, 2002Assignee: Delphi Technologies, Inc.Inventors: Michael C. Wolczak, Christopher E. Schaefer, Robert C. Beer, Brad T. Hanauer

Patent number: 6276960Abstract: A power connector system includes a female connector and a male connector. The female connector includes a female terminal in a female housing. The female terminal is in the form of a U-shaped channel defining a recess. A U-shaped contact member in the channel recess forms a second recess. The male connector includes a male terminal in a male housing. The male and female housings are releasably connected together with the male terminal extending into the recess in the contact member.Type: GrantFiled: August 29, 2000Date of Patent: August 21, 2001Assignee: Delphi Technologies, Inc.Inventors: Christopher E.

Patent number: 6139351Abstract: A high power connection system adapted for automotive environments which provides environmental and EMI shielding includes a female connector, a male connector, and a panel mount. The female connector includes a female connector base and a snap fitted female connector cover. The male connector includes a male connector base and a snap fitted male connector cover. The female connector base has at least one female power terminal cavity for seatably receiving a respective female power terminal. The male connector base has at least one male power terminal cavity for seatably receiving a respective male power terminal. The female connector is covered by a cover seal and a conductive shroud. A pair of lock arms protrude outward from the front end of the male connector base, pass through the panel mount and interface with a lever of a lever rotatably connected to the shroud to thereby mechanically assist mating of the male and female connectors.Type: GrantFiled: November 12, 1999Date of Patent: October 31, 2000Assignee: Delphi Technologies, Inc.Inventors: Christopher E. Schaefer, Robert C. Beer, Mark D. McCall

Patent number: 4846219Abstract: A pressure relief by-pass control valve in a system flowing fluid of changing temperature. The vale incorporates a signalling mechanism to indicate when differential pressures have put the valve in a by-passing mode, including an indicator button displaceable by a valve member in moving toward an open position. Temperature responsive structure closes and opens a gap in the connection between the valve member and the indicator button. As used with a heat exchanger, the valve signals the fact of a clogged heat exchanger core, while obviating giving of a false signal when high pressure differentials resulting from low temperature operating conditions occur.Type: GrantFiled: January 15, 1988Date of Patent: July 11, 1989Assignee: Parker-Hannifin CorporationInventor: Christopher E.
