Publication number: 20090215325Abstract: Stiff and soft materials each provide certain advantages when used in the manufacture of separable insulated connectors, such as elbow and T-body connectors. Utilizing a shell or an insert that includes one section made from a stiff material and one section made from a soft material can provide a separable insulated connector that capitalizes on the advantages associated with both types of materials. The stiff materials and soft materials can be placed strategically on the shell or insert of the separable insulated connector to maximize the advantages of each material. For example, the stiff material can be used to form a section of the separable insulated connector where strength and durability is most desirable, and conversely, the soft material can be used to form a section of the connector where flexibility is desirable. A relatively stiff band can be provided around a relatively soft portion of a connector.Type: ApplicationFiled: October 3, 2008Publication date: August 27, 2009Applicant: Cooper Technologies CompanyInventors: David Charles Hughes, Thomas Augustin

Publication number: 20090215294Abstract: Separating connector assemblies of a separable connector system. The separable connector assemblies include one or more pairs of connectors configured to engage and disengage one another in electrical connection and disconnection operations, respectively. An operator can disengage the connectors by pushing the connectors together and then pulling the connectors apart. Pushing the connectors together shears interface adhesion between the connectors, making it easier for the operator to pull the connectors apart. One of the connectors can include a nose end having an undercut segment configured to not engage an interior surface of the other connector when the connectors are engaged. Limiting the surface area of the nose end that interfaces with the interior surface of the other connector reduces surface adhesion and a pressure drop when separating the connectors, making separation easier to perform.Type: ApplicationFiled: February 25, 2008Publication date: August 27, 2009Applicant: Cooper Technologies CompanyInventor: David Charles Hughes

An operator can disengage the connectors by pushing the connectors together and then pulling the connectors apart. Pushing the connectors together shears interface adhesion between the connectors, making it easier for the operator to pull the connectors apart. An indicator integral or coupled to one of the connectors can indicate whether the first and second connectors are in the pushed-in-position. A window in the other connector includes an opening, channel, and/or translucent or semi-translucent material through which the indicator may be seen. The window and/or one or more vents in a tubular member of one of the connectors can include a channel that provides an air path for ingress of air between the connectors, to thereby remove or reduce a vacuum or partial vacuum between the connectors.Type: ApplicationFiled: December 19, 2008Publication date: August 27, 2009Applicant: Cooper Technologies CompanyInventor: David Charles Hughes

Publication number: 20090211089Abstract: A dual interface separable insulated connector comprising a faraday cage molded over a bus bar for use in an electric power system and a method of manufacturing the same are provided. The faraday cage can be disposed within a semi-conductive shell. The configuration of the separable insulated connector can provide for easier bonding between the faraday cage and insulating material. Additionally, the configuration can eliminate or reduce the need to coat the bus bar with an adhesive agent and to smooth the metal bus bar to remove burrs, other irregularities, and sharp corners from the bar. Manufacturing the dual interface separable insulated connector can include molding a semi-conductive rubber faraday cage over a conductive bus bar, inserting the faraday cage into a shell, and injecting insulating material between the faraday cage and shell.Type: ApplicationFiled: February 25, 2008Publication date: August 27, 2009Applicant: Cooper Technologies CompanyInventors: David Charles Hughes, Mark Clifford Kadow, Michael John Gebhard, SR.

Patent number: 7562554Abstract: A method for calibrating a valve having a valve element movable between a flow blocking position and a flow passing position includes pressurizing fluid directed to the valve, increasing a current directed to the valve for controlling a position of the valve element, and sensing a pressure of the fluid. The method for calibrating the valve also includes determining if a time-derivative of the sensed fluid pressure is greater than a predetermined threshold over a predetermined period of time, and determining a cracking point current command directed to the valve. The cracking point current command is directed to the valve when the time-derivative of the sensed fluid pressure is greater than the predetermined threshold.Type: GrantFiled: August 31, 2006Date of Patent: July 21, 2009Assignees: Caterpillar Inc., Shin Caterpillar Mistubishi LtdInventors: Benjamin Yoo, Eric Charles Hughes, Rick Dean Vance

Additionally, the connections can automatically be merged into a harness bundle.Type: GrantFiled: March 23, 2006Date of Patent: July 7, 2009Assignee: Dassault Systemes SolidWorks CorporationInventors: Andrew Charles Hughes, Gordon Norrie

Publication number: 20090111324Abstract: A separable connector shield housing includes a layer of conductive material disposed at least partially around a layer of non-conductive material. The layers are molded together. For example, the conductive material can be overmolded around the non-conductive material, or the non-conductive material can be insert molded within the conductive material. The molding results in an easy to manufacture, single-component shield housing with reduced potential for air gaps and electrical discharge. The shield housing defines a channel within which at least a portion of a contact tube may be received. A contact element is disposed within the contact tube. The conductive material substantially surrounds the contact element. The non-conductive material can extend along an entire length of the contact tube and other components, or it may only extend partially along the contact tube. The non-conductive material can include an integral nose piece disposed along a nose end of the contact tube.Type: ApplicationFiled: December 22, 2008Publication date: April 30, 2009Applicant: Cooper Technologies CompanyInventors: David Charles Hughes, Paul Michael Roscizewski

Publication number: 20090108847Abstract: A fuse test and ground device includes an insulated housing with a bore that extends from the front of the housing towards the rear of the housing. An electrical contact is disposed partially within the bore. A current interrupter, such as a fuse, is electrically connected between the contact and a testing ground lead. An eye, having it's surface insulated by the housing, can be attached to the housing and provide a connection point for manipulation of the device. A grounding bore extends from a second aperture into the housing and provides an electrical connection to the contact. A grounding plug can be connected to ground on one end and inserted into the grounding bore to create a permanent ground for the device. An annunciator is connected to the current interrupter such that the annunciator provides an indication when a current flows through the current interrupter.Type: ApplicationFiled: October 31, 2007Publication date: April 30, 2009Applicant: Cooper Technologies CompanyInventors: David Charles Hughes, Steven Guy Whitmore
