US Classification:

335 6, 335189, 335190, 200244

Abstract:

A lockable fastener connects together a plurality of components of a circuit breaker and maintains electrical conductivity between the components while permitting relative movement therebetween. The lockable fastener includes a first clinch nut member and a second clinch bolt member. The clinch nut member includes a threaded cavity formed therein, a side having opening therein, and a passageway between the side at the opening and a surface proximate the threaded cavity. The clinch bolt member includes a threaded shank. At least a portion of the threaded shank is threadably receivable in the threaded cavity of the clinch nut member, in order to axially align the clinch nut and clinch bolt members. The clinch nut and clinch bolt members are adapted to be locked by deformation of the surface of the clinch nut member to prevent loosening of the members.

Abstract:

A heater assembly is provided for an electrical switching apparatus. The heater assembly includes a heater element and an elongated bimetal. The heater element includes first and second ends, an intermediate portion disposed therebetween and an aperture disposed proximate the first end. The elongated bimetal includes opposing first and second ends, and is movable between first and second positions corresponding respectively to the separable contacts of the electrical switching apparatus being closeable, and to the first end of the elongated bimetal cooperating with a trip bar to cause an operating mechanism to open the separable contacts. The second end of the elongated bimetal is coupled to the intermediate portion of the heater element. When the elongated bimetal is disposed in the first position, the first end of the elongated bimetal extends beyond the upper surface of the first end of the heater element into the aperture of the heater element.

International Classification:

H01H 7710

US Classification:

200244

Abstract:

A molded case circuit breaker has a moving conductor assembly which includes a modular carrier assembly incorporating a plurality of spring biased contact cam members each of which engages contact pressure lobes on a pair of contact arm laminations to provide contact pressure. In response to the magnetic repulsion forces generated by a short circuit, the springs compress allowing the cam members to pivot and side step the contact pressure lobes so that the contact arm blows-open with little resistance. The cam members and springs are preassembled in a transverse channel in the carrier body and laterally retained in place by side plates for easier pivotal attachment of the contact arm laminations to the lobes on the side plates. The side plate lobes raise the contact arm relative to the mass of the carrier to reduce eddy current heating and provide a positive off indication for welded contacts by restricting movement of lower toggle links of the operating mechanism which are coplanar with the side plates. A modular crossbar includes molded bearings engaged by or made integral with hexagonal metal shaft sections which extend into hex openings in the carrier bodies of adjacent poles.

International Classification:

H01H 7500

US Classification:

335 16

Abstract:

The helical contact compression springs of a circuit breaker are preassembled in a contact clip for easier assembly of the circuit breaker. The bottom wall of an elongated trough formed by the clip is pierced by holes forming cylindrical protrusions extending into the trough. The clip is placed over the springs supported in a row in a fixture. A die head presses on the spring clip to compress all the springs and then simultaneously insert punches into the holes in the clip to expand the protrusions and secure the springs to the clip. The fixture includes a slide mounted on guides for movement between a loading position and an operating position under the die head. A support block is pivoted on the slide to present one of two sets of spring recesses for circuit breakers having different current ratings with the slide in the loading position.

US Classification:

335202

Abstract:

A gas deflector for a line-in connector of a circuit breaker. The gas deflector is coupled to a collar with a top and a cavity, a threaded opening through the top, a screw threaded in the threaded opening. The collar is attached to the line-in for the circuit breaker. The gas deflector is an L-shaped shield with an integral screw sleeve and a slot sized to allow a terminal strap to pass therethrough. The terminal strap is connected to the collar. The shield device covers the collar top and the cavity and is held in place by the screw passing through the sleeve and by the terminal strap passing through the slot. The shield substantially reduces the amount of ionized gas infiltrating into the collar.

International Classification:

H01R 436

US Classification:

439813

Abstract:

A terminal connection for a flat stab of an electrical terminal includes a spring clip which retains a nut in alignment with an aperture in the flat stab. The spring clip is fabricated from a strip of resilient electrically conductive material and has a top wall with a central aperture, side walls extending downward from the top wall and having slots therein, and outwardly projecting flanges on the bottom edge of each of the side walls. A square nut is retained in the spring clip by lateral projections on the nut engaged in the slots in the side walls with the tapped hole in the nut aligned with the aperture in the top wall of the clip. The fastener assembly clips onto the end of the flat stab which is in a recess in the electrical terminal, with the stab between the nut and the top wall of the spring clip. The outer edges of the flanges on the spring clip frictionally engage against the opposite sides of the recess in the terminal to retain the spring clip and nut in the terminal until a screw is passed through the apertures in the top wall and the flat stab engages the nut to secure a conductor to the stab. The slots in the side walls of the clip prevent rotation of the nut and provide positive stops which resist loss of the nut through application of excessive axial force to the screw.

International Classification:

US Classification:

Abstract:

A molded case circuit breaker has modular crossbar members which connect the contact arm carriers of a desired number of poles for opening and closing the separable contacts of all of the poles simultaneously by a single spring powered operating mechanism. The modular crossbar members comprise shaft sections which engage openings in the contact arm carriers of adjacent poles. Bearings support the shaft sections and mount the contact arm carriers for rotation about a common pivot axis. In a preferred embodiment of the invention, the modular crossbar member is a single continuous metal shaft overmolded with an electrically insulative resin which also forms the bearing. Alternatively, separate metal shaft sections seat in sockets on either side of the molded bearing. In both instances, the shaft sections are keyed to the openings in the contact arm carriers for transmission of torque. In the exemplary crossbars, the shaft sections are hexagonal in cross-section.
