Patent number: 8398436Abstract: A stackable cable mount power connector includes a cover having a draw screw engagement pin and a connector shell having a bushing and an insert assembly positioned therein. A draw screw having a locking pin is positioned within the bushing. The bushing includes grooves for receiving the locking pin. The connector includes multiple primary contact pins having an upper portion and a lower portion. The upper portion of the primary contact pins is positioned within the bushing. The lower portion of the primary contact pins is positioned within the insert assembly. The upper portion of the primary contact pins is configured to receive secondary contact pins. The lower portion of the primary contact pins is configured to engage a power source. The connector also includes a stud positioned within the insert assembly. The stud includes slots for receiving the locking pin.Type: GrantFiled: November 16, 2009Date of Patent: March 19, 2013Assignee: Cooper Technologies CompanyInventors: Charles P. Fischer, Jack S. Bush

Patent number: 4728304Abstract: An improved lead socket insert assembled into a contact member which is adapted to pluggably receive a lead of a circuit component, such as an integrated circuit package is provided. The insert has a hollow cylindrical body portion and fingers that are bent at a fulcrum position so that they converge. The insert has improved operational characteristics which engage a component lead with greatly reduced mating forces due to a weakening at the fulcrum position. The lead socket insert allows for higher density application of electronic packages when assembled into loose contact members or directly mounted into an interconnection panel.Type: GrantFiled: April 2, 1985Date of Patent: March 1, 1988Assignee: Micro Stamping Corp.Inventor: Charles P. Fischer

Patent number: 4621887Abstract: This invention is an electrical contct that includes an inner sleeve (10) that is stamped and formed from a single sheet of metal and is characterized by a plurality of apertures (11) in the sleeve (10) that have an axis of symmetry (11a) or a straight side (13) that is at an acute angle with the central axis (10a) of the sleeve.Type: GrantFiled: March 9, 1981Date of Patent: November 11, 1986Assignee: Allied CorporationInventors: R. Amelia Piscitelli, David O. Gallusser, David L. Frear, Valentine J. Hemmer, Charles P. Fischer

Patent number: 4374604Abstract: In order to prevent the rotation of an electrical contact 30 within a connector assembly housing 3 the contact 30 is provided with a plurality of radial fins 37 which are located within a space between resiliently deflectable fingers 21 which are part of the contact retaining insert 20. Because the contact 30 does not rotate, the winding of a wire around the wire receiving portion 38 of the contact is facilitated.Type: GrantFiled: March 5, 1981Date of Patent: February 22, 1983Assignee: The Bendix CorporationInventors: Valentine J. Hemmer, R. Amelia Piscitelli, Charles P. Fischer, James C. Washburn

Patent number: 4373773Abstract: This invention is a three piece contact assembly of the type having an inner sleeve (10), a forward sleeve (20), and a rear sleeve (30), wherein the inner sleeve is characterized by a dual thickness. The forward portion of the inner sleeve 10 has a thickness (T) greater than the thickness (t) of the rear wire receiving end thereby strengthening the deflectable fingers (14) at the mating end of the inner sleeve (10).Type: GrantFiled: January 26, 1981Date of Patent: February 15, 1983Assignee: The Bendix CorporationInventors: R. Amelia Piscitelli, Valentine J. Hemmer, Charles P. Fischer, Eric F. Shepler

Patent number: 4357742Abstract: An apparatus for forming brush contacts from spools of wire and holders for angular ended wire segments cut from said wires, has a wire feeding means for feeding spools thereof independently of each other, a cutting device for cutting segments from the wires and feeding the segments to a common collection point where the segments are loaded into the holders provided, and a crimping device for crimping the holder to retain the wires therein without causing flaring of the exposed ends. A checking station is provided to determine whether each brush contact contains the requisite number of wire segments and ejection means to eject defective contacts. The completed contacts are collected in such a manner as to prevent damage thereto.Type: GrantFiled: May 27, 1980Date of Patent: November 9, 1982Assignee: The Bendix CorporationInventors: Charles P. Fischer, Andrew A. Peterson, Edward J. Doi, Rodney W. Gossoo, Jan C. Mitrzyk, Sr.

Patent number: 4309928Abstract: An apparatus for simultaneously cutting wire segments having acutely angled ends from a plurality of wires including guide apparatus and feeding apparatus for the wires, and a cutting device comprising a base, reciprocable shear plate and clamp plate, each of which has parallel grooves therein, with each also having sliding surfaces that are at an acute angle to the axis of the grooves. A collection plate is also provided to contain cut segments and transfer the segments to a common collection point.Type: GrantFiled: May 27, 1980Date of Patent: January 12, 1982Assignee: The Bendix CorporationInventors: Jan C. Mitrzyk, Sr., Rodney W. Gossoo, Charles P. Fischer, Howard N. Silvernail, Charles Null

Patent number: 4278317Abstract: A socket contact is disclosed for miniature electrical connectors of the plug and receptacle type. The socket contact (10) comprises a contact sleeve (12) with two contact fingers (66) each extending as a cantilever beam from its root in the sleeve. A reenforcing ridge (68) in each finger extends from a point spaced from the free end of the contact finger to a point past the root of the finger to increase the stiffness of the finger. The radius of each finger and the location of the ridge thereon is such that the ridge is not engaged by a mating contact pin upon insertion into the socket.Type: GrantFiled: August 31, 1979Date of Patent: July 14, 1981Assignee: The Bendix CorporationInventors: David O. Gallusser, David L. Frear, Charles P. Fischer
