Publication number: 20020100606Abstract: Disclosed is a panel feedthrough that provides insulation, strain relief, and selective attenuation of electrical signals by ferromagnetic means. The feedthrough consists of an externally toothed sleeve that has a fixed restraining flange, a ratcheting cap and, optionally, an additional locking ring, both of which engage teeth on the sleeve. Panel clamping action occurs when a panel is pressed between the cap or locking ring and the restraining flange of the sleeve. Various combinations of ferrite toroids or beads may be added over the outside of the sleeve and held in place by the cap or locking ring. The clamping of wires, cables or other objects passing through the feedthrough is accomplished by inward deflecting, tapered tabs located at one end of the sleeve. These tabs are deflected into a clamping action by the cap bearing a tapered hole into which the tabs are forced.Type: ApplicationFiled: January 30, 2001Publication date: August 1, 2002Inventors: Mathew G. Rule, Randolph W. McKernan

Patent number: 6339195Abstract: Removing the electrical field from the internal volume of high-voltage structures; e.g., bushings, connectors, capacitors, and cables. The electrical field is removed from inherently weak regions of the interconnect, such as between the center conductor and the solid dielectric, and places it in the primary insulation. This is accomplished by providing a conductive surface on the inside surface of the principal solid dielectric insulator surrounding the center conductor and connects the center conductor to this conductive surface. The advantage of removing the electric fields from the weaker dielectric region to a stronger area improves reliability, increases component life and operating levels, reduces noise and losses, and allows for a smaller compact design. This electric field control approach is currently possible on many existing products at a modest cost. Several techniques are available to provide the level of electric field control needed.Type: GrantFiled: September 11, 2000Date of Patent: January 15, 2002Assignee: The Regents of the University of CaliforniaInventors: Michael J. Wilson, David A. Goerz

Patent number: 6294733Abstract: An indexing ring providing automatic continuity between metallic parts of an operator interface device and a support panel in which the operator interface device is mounted. Continuity between the operator interface device and support panel is automatically provided by a continuity rib integrally formed from the indexing feature of an indexing ring. The indexing ring is installed between the operator interface device and the support panel to ensure the relative position of the operator interface device with the support panel. As the indexing feature of the indexing ring is slidably received within the indexing features of the support panel and operator interface device a generally sharp distal edge of the continuity rib will cut through any corrosion protection, such as paint, which might be covering the support panel. Thus, a metal-to-metal connection providing electrical continuity is automatically established and maintained between the operator interface device, indexing ring and the support panel.Type: GrantFiled: December 22, 1999Date of Patent: September 25, 2001Assignee: Square D CompanyInventors: Donald G. Gibbons, Jackie C. Sullivan

Patent number: 6294740Abstract: A one-piece spring clip is provided for retaining a gas tube element used in a surge arrestor having a cap with an interior portion. The spring clip includes a generally flat disk having a periphery, a first side and a second side. A plurality of first tabs extend from the first side of the disk at the periphery thereof to retain the gas tube element. A plurality of second tabs extend from the second side of the disk at the periphery thereof to provide a spring force between the interior portion of the cap and the gas tube element.Type: GrantFiled: September 20, 1999Date of Patent: September 25, 2001Assignee: Andrew CorporationInventor: Kendrick Van Swearingen
