20090093988 | Virtual crimp validation system - A system for validating a proposed crimp includes a pre-crimp modeler configured to establish a geometry for the proposed crimp, a plurality of virtual testing modules configured to determine at least one characteristic of the proposed crimp, and a virtual validation module configured to compare results from each of the plurality of virtual testing modules to predetermined criteria. | 04-09-2009 |
20100087105 | ELECTRICAL CONNECTION SYSTEM FOR USE ON ALUMINUM WIRES - A connection mechanism includes a metal segment in mechanical and electrical communication with the remainder of the connection mechanism on at least one side. The segment includes at least one tab protruding from the segment on a first side and a central area of the segment with a plurality of metal deformations. When the metal deformations are pressed into aluminum, they are capable of piercing through corrosion on the surface of the aluminum in order to make electrical contact with the aluminum. | 04-08-2010 |
20100120288 | Multi-level electrical terminal crimp - A cable assembly includes a terminal crimped to a conductor. The terminal has a plurality of crimps spaced from one another and a transition crimp disposed therebetween. A method includes deforming the terminal about the conductor to define the plurality of crimps having different crimp heights, and deforming the terminal about the conductor to define the transition crimp between each of the plurality of crimps. The transition crimp has a crimp height different than each of the plurality of crimps. | 05-13-2010 |
20130029523 | WIRE CABLE ASSEMBLY AND METHODS OF MAKING THAT HAVE A CRIMP CONNECTION THAT CONTAINS A PAIR OF HUMPS AND A GROOVE DISPOSED THEREBETWEEN TO REDUCE BROADCAST RF ENERGY THEREFROM - A crimp connection includes a contact element and a wire cable. The wire cable is disposed along a longitudinal axis and configured to axially receive the contact element. When the contact element receives the wire cable the crimp connection is formed that attaches the wire cable with the contact element so that at least a portion of the crimp connection includes at least one indention arrangement deformed therein. The indention arrangement contains a pair of humps separated by a groove therebetween. The crimp connection may be applied to a wire cable assembly that includes an inner and an outer ferrule in a manner that prevents protrusions from forming thereon so that undesired RF energy is not electrically transmitted out from crimp connection of the wire cable assembly. Methods to construct a crimp connection that includes the pair of humps separated by a groove therebetween are also further presented. | 01-31-2013 |
20130045610 | CONTACT ELEMENT INCLUDING HELICAL ARRANGEMENT DEFINED IN INTERNAL SURFACE - An electrically-conducting contact element includes a section of the contact element defining an aperture. The section is configured to receive a wire cable within the aperture for attachment thereto. The section includes an internal surface with at least one cutout arrangement formed thereon. A wire assembly that includes the electrically-conducting contact and a method to construct the electrically-conducting contact are also presented. The method includes a step of providing the contact element and forming at least one cutout arrangement on the internal surface of the contact element. A further step in the method includes altering material on the internal surface of the contact element by a forming means. The forming means may be one of milling, rifling, machining, cutting, indenting, or stamping. A wire assembly and a vehicular electrical wiring harness that respectively include the contact element are also further presented. | 02-21-2013 |
20130115828 | ELECTRICAL CONTACT HAVING KNURL PATTERN WITH RECESSED RHOMBIC ELEMENTS THAT EACH HAVE AN AXIAL MINOR DISTANCE - An electrical contact includes a knurl pattern disposed along at least a portion of an interior surface of the electrical contact. The portion receives a lead of a wire cable along a longitudinal axis and is attached thereto to form a crimp connection. The knurl pattern includes a plurality of recessed elements and each recessed element has a rhombus shape that includes inner corners. An orientation of a first pair of opposing, generally axial inner corners define an axial minor distance therebetween and an orientation of a second pair of opposing, inner corners define a major distance therebetween. The axial minor distance is less than the major distance. The recessed elements of the knurl pattern are especially suitable for engagement with an aluminum wire cable to form the crimp connection. A wire assembly that includes the crimp connection is associated with a cable harness disposed in a motorized vehicle. | 05-09-2013 |
20130115830 | ELECTRICAL CONTACT HAVING SERRATION WITH ANGLED SIDEWALLS AND ROMBOID KNURL PATTERN THAT INCLUDES ELEMENTS HAVING AN AXIAL MINOR DISTANCE - An electrical contact includes at least one grooved channel defined in an interior surface of the electrical contact along at least a portion the electrical contact disposed along a longitudinal axis. The portion is configured to axially receive a lead of a wire cable for attachment thereto and thereby allow the attached lead to at least engagingly make contact against a recessed surface of the grooved channel. The grooved channel has a depth and includes at a least one sidewall extending along the depth. The sidewall includes at least one section that angularly extends from the interior surface to a point recessed from the interior surface disposed on the sidewall along the depth. | 05-09-2013 |
20140033530 | METHOD OF FORMING A CONTACT ELEMENT INCLUDING A HELICAL GROOVE DEFINED IN AN INTERNAL SURFACE - An electrically-conducting contact element includes a section of the contact element defining an aperture. The section is configured to receive a wire cable within the aperture for attachment thereto. The section includes an internal surface with at least one groove having sharp edges formed therein. A wire assembly that includes the electrically-conducting contact and a method to construct the electrically-conducting contact are also presented. The method includes a step of providing the contact element and forming a sharp edge on the internal surface of the contact element. A further step in the method includes altering material on the internal surface of the contact element by a forming means. The forming means may be one of milling, rifling, machining, cutting, indenting, or stamping. A wire assembly and a vehicular electrical wiring harness that respectively include the contact element are also presented. | 02-06-2014 |
