After attachment of a contact (23, 24) to a conductor, the attached contact assembly (20, 20') is cut from the strip (22) and the strip (22) is indexed to deliver the next contact assembly (20, 20') to the attachment station (14).Type: GrantFiled: February 1, 1988Date of Patent: July 25, 1989Assignee: AMP IncorporatedInventors: Randolph E. Capp, Ronald C. Laudig, George W. Michael, III

Patent number: 4834682Abstract: A braided wire electrical connector employs eyelets of one-piece integral form for providing electrical connections with a termination point. Integral arms extend from an eyelet head and are crimped to the braided wire to fasten the eyelet to the braided wire.Type: GrantFiled: January 19, 1988Date of Patent: May 30, 1989Inventors: William T. Auclair, Randolph L. Auclair

Patent number: 4832622Abstract: An endless electrical connector has a continuous header manufactured by forming axial segments in sequence. In the case of continuous extrusion, the axial segments are infinitesimal in length, whereas in the case of semicontinuous injection molding, the segments have discrete length.Type: GrantFiled: January 23, 1987Date of Patent: May 23, 1989Assignee: Autosplice, Inc.Inventor: Irwin Zahn

Patent number: 4776651Abstract: Socket contact (10) has cantilever arms (16) which are stamped without blanking any strip stock from therebetween, each pair of arms (16) being framed with transition portions 24) which diverge from the axis of the terminal (10) to provide space between facing sheared edges (18, 20). A centerline spacing of 0.109 inches in strip form is achieved. Furthermore, a contact (10) insertion feature (150) for applying an insertion force to insert the contact (10) into a terminal receiving passage (124) of an electrical connector without causing the contact (10) to skive the interior surface of the passage (124). A portion of retaining plate (29) is formed out of the plane thereof to define a vertical surface (151) facing opposite the direction of insertion of contact (10). The insertion feature (50) is formed early in the formation of contact (10); vertical surface (151) is used as a reference from which the outer features of contact (10) are referenced.Type: GrantFiled: February 6, 1987Date of Patent: October 11, 1988Assignee: AMP IncorporatedInventor: James A.

Patent number: 4753003Abstract: An improved bandoleer of contact carriers for use in a power crimping tool is provided by assembling a plurality of separate contact carriers. Each contact carrier has a uniform exterior size and shape and is further provided with a male connector radially extending from one side, and the diametrically opposite side of the contact carrier is provided with a female connector radially extending from the contact carrier. The female and male connectors are arranged and configured to resiliently couple to corresponding and appropriate opposite connectors with the adjacent contact carrier in the bandoleer. The male connector is a longitudinal web having a longitudinal bulbous portion. The female connector is a socket connector having a restricted opening smaller than the bulbous portion of the male connector. However, the inherent resiliency of the female socket allows the restricted portion to expand to permit passage of the bulbous portion of the male connector into the female socket.Type: GrantFiled: May 21, 1987Date of Patent: June 28, 1988Assignee: McDonnell Douglas Corp.Inventor: Richard W. Gobeil

Patent number: 4740180Abstract: A low insertion force mating electrical contact structure is provided in a male terminal including a final contact portion and a forwardly extending lead-in portion having a gradual twisted cross section relative to the final contact portion. In a preferred embodiment, the male terminal is adapted to mate with a dual contact cantilever spring arm female terminal. Opposed smooth-milled surfaces on the male terminal extending through the lead-in portion to the final contact portion engage the female contact portions and gradually cam the female contacts outwardly to provide reduced insertion forces on the male pin during insertion.Type: GrantFiled: March 16, 1987Date of Patent: April 26, 1988Assignee: Molex IncorporatedInventors: Frank A. Harwath, Paul L. Rishworth

Patent number: 4718166Abstract: A high reliability low cost connector has flat retainers blanked from an electrically conductive sheel metal and inserted into opening in an electrically insulating body. Each retainer has a post at one end extending from an opening at one side of the body and has a pair of integral wings spaced from each other in a plane at its opposite end disposed in the opening at the opposite side of the body. Spring clips are blanked and formed from an electrically conductive sheet metal spring material and are inserted into the body openings so loop portions of the clips fit between the pairs of retainer wings in each opening and are biased into resilient electrical engagement with the retainer wings. Each clip preferably has two pairs of juxtaposed spring leaves integral with the loop spaced at 90.degree. relative to each other around a common axis to grip a terminal inserted between the spring leaves. The loops are also formed with interruptions in each loop in a common location between two adjacent spring leads.Type: GrantFiled: January 21, 1986Date of Patent: January 12, 1988Assignee: Texas Instruments IncorporatedInventors: Pietro DeFilippis, Amedeo Salvatore, Marios Biscione

Patent number: 4712299Abstract: A plurality of contacts are stamped out of flat sheet metal stock simultaneously with blank forming female rectangular contact boxes initially flat, with a male contact extending therefrom, and with each box material blank joined to a common carrier strip extending longitudinally of the contact array. The flat box material blanks are initially equal to or slightly less than a fraction of the distance D between uniformly spaced holes within the holder. While maintaining the contacts linked to the carrier strip, the lateral side edges of the box material blanks are bent up and swaged to thin the box material portions and laterally expand those portions, widthwise, in excess of D.Type: GrantFiled: February 21, 1986Date of Patent: December 15, 1987Assignee: Electronic Plating Service, Inc.Inventors: Heinz Loewen, Wold Wenko

Patent number: RE32688Abstract: A method of packaging solid members having rigid projections, e.g., electrical connectors, on a flexible foam substrate assembly. The method generally includes disposing a portion of the substrate at a workstation and causing the solid member to move toward the substrate so that the projections penetrate the substrate to removably mount said solid member therein. This procedure is repeated as different portions of the substrate are presented to the workstation until a desired number of solid members have been mounted on the substrate. The substrate can then be reeled or arranged in such a manner to be mounted within a suitable container for future removal of the solid members from the substrate.Type: GrantFiled: May 22, 1987Date of Patent: June 7, 1988Assignee: Molex IncorporatedInventor: Thor Olson
