摘要： 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.

摘要： A circuit interrupter including a housing, separable main contacts disposed in the housing, and an operating mechanism disposed in the housing and interconnected with the contacts. The housing has a cover securable to a base, with the cover including a downwardly-facing abutment portion. An electrical terminal is releasably disposed within the base and has a tab that abuttingly engages the abutment portion of the cover when the cover is secured to the base. The base also includes channels formed in the sides of the base, and the electrical terminal includes sides that insert into the channels and that include rib portions that frictionally engage the channels upon insertion. The base also includes tapered sides, with the electrical terminal sides being tapered in order to follow or mirror the tapered sides of the base.

摘要： 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.

摘要： A terminal connection for a flat stab of an electrical switch 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, an end wall extending downward from the top wall and a bottom wall cantilevered forward from the bottom of the end wall under the top wall and between the side walls. A square nut is retained in the spring clip with its tapped hole aligned with the aperture in the top wall and with either an aperture or a depression in the bottom wall. The fastener assembly clips onto the end of the flat stab with the stab between the nut and the top wall of the spring clip. A screw 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.
