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： An improved lockable fastener that can be employed in a circuit breaker application includes a first member and a second member that are threadably cooperable with one another and a locking member that extends between the first and second members to resist loosening of the first and second members. The second member includes a threaded shank that is threadably received in a first threaded portion of a cavity formed in the first member. The locking member includes a threaded body and a taper, with the threaded body being threadably receivable in a second threaded portion of the first member, and with the taper being at least partially receivable in a receptacle formed in the shank of the second member. The receptacle defines a seat on the shank, and the taper engages the seat to deform at least a portion of the shank into engagement with a ledge that is interposed between the first and second threaded portions of the cavity.

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.

摘要： A spring assembly is provided for a yoke assembly of an electrical switching apparatus including a housing, separable contacts enclosed by the housing, and an operating mechanism structured to open and close the separable contacts. The operating mechanism includes a pole shaft. The yoke assembly is coupled to the pole shaft and is movable among first and second positions corresponding to the separable contacts being closed and open, respectively. The spring assembly includes a number of first springs having a first spring rate and being coupled to the yoke assembly, and a number of second springs having a second spring rate and being coupled to the yoke assembly. The second spring rate is different than the first spring rate. The number of first springs and the number of second springs bias the yoke assembly toward the second position.

摘要： A molded case circuit breaker includes an interlock which prevents the operating handle from being moved from the on position after the main contacts have been welded together. By preventing the operating handle from being moved from the on position during such a condition, the operating handle will indicate the correct status of the main contacts and the operator will be made aware that the main contacts are welded together.
