20090218131 | CONDUIT CONNECTOR - In an embodiment, a conduit connector can comprise: a body comprising a box engagement region capable of engaging an opening in an enclosure and a spring configured to engage the connector and the enclosure. The box engagement region can have a root surface, a leading tab, and a follower tab wherein the root surface and leading tab can be located between a leading edge and a secondary edge. A leading tab perimeter edge and a follower tab perimeter edge define a tab perimeter diameter that is larger than an opening in the enclosure. When the leading tab is inserted into the enclosure the spring can be disposed to engage the secondary edge and the enclosure. | 09-03-2009 |
20090288878 | BUSHING AND A METHOD FOR PRODUCING THE SAME - A bushing is disclosed with a duct for accommodating a conductor which is surrounded by an electrical field grading insulation. The bushing includes a core with a shell encapsulating the grading insulation and a flange surrounding the shell and carrying through holes distributed over its circumference for allowing the bushing to be attached to a wall. The shell and the flange can be in one piece and include an insulating matrix material. The through holes can be surrounded by metal inserts each forming an annular surface flush with a surface of the flange. A test tap can include a contact pin which is electrically conductively connected to an outermost layer of the grading insulation and surrounded by a contact ring connected to every second metal insert by connection wires for grounding the contact pin via the contact ring when the test tap is not in use and covered. The core can be produced by filling a mould with the liquid matrix material after components of the grading insulation and other parts have been fixed in the liquid matrix material. | 11-26-2009 |
20100263925 | Electrical Locking Hub Nut - The invention relates to an electrical connector locking hub nut that does not damage the wiring during pulling, frees up manpower by allowing one person rather than two to be able to do the pulling, has a simplified design, and which has universal threading for conduit of all currently approved sizes and materials. | 10-21-2010 |
20100294562 | ELECTRICAL CONDUCTOR FOR A HIGH-CURRENT BUSHING - An electrical conductor carries a rated current in a high-current bushing of a transformer. The electrical conductor includes a conductor piece which extends along an axis and has a cylindrical envelope surface, a first electrical connection, and a second electrical connection. The first electrical connection has two contact surfaces which are aligned parallel to one another. Electrical losses of the electrical conductor are kept low, with a compact design. This is achieved, in part, because the second electrical connection is connected without a joint to the conductor piece, and the first electrical connection is hollow and, at right angles to the axis, has an oval profile with two longitudinal faces which form the two contact surfaces. In addition, a hollow electrical conductor section is arranged between the first electrical connection and the conductor piece, connects the first electrical connection to the conductor piece, and forms a smooth transition from the two contact surfaces of the first electrical connection to the envelope surface of the conductor piece. | 11-25-2010 |
20110048798 | COLLAR FOR MAINTAINING ELECTRIC CABLES - The invention relates to a collar ( | 03-03-2011 |
20110061931 | Structure for wire outlet covers - An improved structure for a wire outlet cover, arranged at a sidewall of a carton receiving a network wire, includes a body and a collar. The body has a hollow cylindrical shape and includes an inlet end and an outlet end, wherein the body is, at the outlet end, provided with plural stop blocks, and wherein the body is, near the outlet end, provided with a stop flange. The collar has a hollow annular shape and is, at its internal edge, provided with plural axially-extended edges. The collar is assembled to the rear body, with the plural axially-extended edges stopped by the plural stop blocks, such that the collar and the stop flange are spaced apart for a predetermined distance for receiving the sidewall of the carton. Therefore, the network wire will not be twisted when entering into the wire outlet cover nor be twisted around the inlet end. | 03-17-2011 |
20120024597 | SPRING LOCK ELECTRICAL FITTING - A fitting that anchors electrical wiring to a junction box or electrical panel includes gripping members which can releasably hold electrical wiring, in or out of armored conduit, and interference members which allow the fitting to be inserted through knock out apertures and, when in place, extend to prevent withdrawal from the aperture. A rotatable collar actuates the mechanisms and abuts the wall of the box or panel, eliminating any lateral movement when the interference members are engaged | 02-02-2012 |
20120037417 | REMOVABLE PUSH ELECTRICAL FITTING FOR ELECTRICAL METALLIC TUBING OR EMT - An electrical fitting having a gripping device with a plurality of gripping tabs forming a helix or spiral. The electrical fitting permits electrical metallic tubing or EMT to be quickly attached to and removed from the electrical fitting without disassembling the fitting or cutting the tubing. A body with a locking end having a plurality of griping tabs receives an end of the tubing pushed into the fitting. The gripping tabs securely hold the tubing preventing loosening or removal. The helix or spiral formation of the griping tabs permits easy removal of the tubing by rotating the tubing counter-clockwise. | 02-16-2012 |
20130056264 | CABLE GLAND ASSEMBLY FOR TERMINATING CABLE - A cable gland assembly for terminating cable is described herein. The cable gland assembly can include a gland configured to receive a cable, and a gland nut disposed around the gland. A skid washer may be disposed within the gland nut above or below the gland. The cable gland assembly can also include an intermediate body having a first end and a second end, in which the first end may be coupled to the gland nut. The cable gland assembly can further include a body coupled to the second end of the intermediate body, and an intermediate nut disposed around a portion of the body and the second end of the intermediate body. | 03-07-2013 |
20130133943 | SPLIT ELECTRICAL GROUNDING BUSHING WITH SECURELY ATTACHED SECTIONS FORMING CONTINUOUS INSULATION - A split electrical grounding bushing having adjacent bushing portions with insulating bushing portions having guard tabs covering a gap formed between the insulating bushing portions creating a continuous insulating ring. The bushing portions are connected by a hinge permitting the bushing to be placed over electrical conductors or wires after being installed. Gaps in the insulating bushing portion are covered by attached guard tabs improving the safety of a split electrical bushing. Locking tabs and openings are used to securely hold the insulating bushing portions onto the bushing portions. The split electrical bushing is placed on a distal end of an electrical conduit. The split bushing may be an electrical grounding bushing providing an electrical ground connection. | 05-30-2013 |
20140027173 | GROMMET - The present invention provides a grommet having a hollow elongate tubular body with two flexible end-faces each having thicker diameter leading edges that precede thinner diameter catchment areas. | 01-30-2014 |
20160105012 | Conduit Locking Connector - Improvements in a conduit locking connector that connects rigid conduit to an electrical junction box. Rigid conduit provides the benefit of allowing an installer to screw onto the side of the rigid conduit to frictionally lock into the rigid conduit with the conduit locking connector. A screw engages into rigid conduit that provide a hard bearing surface on opposing sides of the screw. This provides minimal bending of the rigid conduit for a firmer grip of the rigid conduit to the conduit locking connector. The conduit locking connector provides a physical interface that locks onto the rigid conduit and locks onto the junction box. The conduit locking connector provides anti-rotation between the rigid conduit and the junction box. Anti-rotation is with tabs that extend below a planar surface of the conduit locking connector and engage into holes in recesses in the junction box. | 04-14-2016 |
