The disclosed concept relates to electrical switching apparatus, such as, but not limited to, molded case circuit breakers, and more particularly, to a connector assembly for mechanically and electrically connecting the accessory components housed within the electrical switching apparatus to equipment located outside of the electrical switching apparatus.

The disclosure provides a socket that can easily secure internal insulation. The socket includes a box-shaped first housing and a second housing attached to the first housing. The first housing includes a first wall and a second wall. The first wall extends in a width direction that intersects an opening surface, and has a first opening for inserting a screw member that fixes a conductor part of a wire. The second wall extends in a direction that intersects the opening surface and the first wall, and has a second opening for inserting and removing the conductor part of the wire. The second housing includes a second housing body and a locking arm. The second housing body covers the opening surface. The locking arm extends from the second housing body in the width direction and is locked to the first housing in the width direction.

A thermal protector (1) including two fixed contacts (13A, 13B) provided at the end part of conduction terminal pins (5A, 5B) projecting into a metallic enclosed container (100), a support (6) arranged in a case, an oscillatory heating resistor (8) supported by the support and having two movable contacts (9A, 9B) facing the fixed contacts, and a heat responsive body (10) interposed between the heating resistor and the support and coupled with the heating resistor through a coupler (12). When an overcurrent flows through the heating resistor to generate heat therefrom and the temperature of the heat responsive body reaches a set level, the heat responsive body is inverted. Inverting motion of the heat responsive body is transmitted to the heating resistor through the coupler, and the current path is opened.

A switch device includes a body with a switch member pivotably engaged with a top opening of the body and a first terminal and a second terminal respectively extend through a bottom of the body. A bimetallic plate has a first end fixed to the first terminal and includes a first contact point which is located above a second contact point on the second terminal. A link has an upper end pivotably connected with a protrusion on an underside of the switch member and a lower end of the link clamps the second end of the bimetallic plate. The protrusion includes an engaging hole and an extension slot is in communication with the engaging hole. The upper end of the link has a biasing plate which contacts a contact portion in the body so as to provide a potential force to keep the link upright. When overload, the bimetallic plate is deformed upward and the upper end of the link is moved into the extension slot to ensure that the bimetallic plate is deformed completely.

An interconnect assembly for a switching assembly in which the switching assembly includes a bus bar and an electromagnetic switching device having a contactor bus. The interconnect assembly is structured to mechanically couple and electrically connect the contactor bus to the bus bar. The interconnect assembly includes a socket member structured to engage the bus bar, a post assembly that includes a post member structured to extend through the contactor bus, in which at least a portion of the post member extends into the socket member, and a locking member disposed on the post member. The locking member is structured to extend through and removably engage the socket member in order to mechanically couple and electrically connect the contactor bus to the bus bar.

Disclosed herein is a power switching module for a battery module assembly constructed in a structure in which a plurality of rectangular battery modules, each having a plurality of battery cells or unit modules connected in series to each other, are stacked in the width direction (the longitudinal direction) and the height direction (the transverse direction) by at least twos such that the rectangular battery modules generally constitute a hexahedral structure (hexahedral stack), outer edges of the hexahedral stack are fixed by a frame member, and input and output terminals of the rectangular battery modules are oriented such that the input and output terminals of the rectangular battery modules are directed toward one surface (a) of the hexahedral stack, wherein the power switching module comprises an insulative substrate mounted to the surface (a) of the hexahedral stack in a coupling fashion, elements mounted on the insulative substrate for controlling voltage and current during the charge and discharge of the rectangular battery modules, and connection members mounted on the insulative substrate for interconnecting the control elements.

An appliance assembly includes an appliance and an appliance member. The appliance includes a wall defining a plurality of holes. The appliance member is carried by the appliance. The appliance member includes a housing which includes a snap-fit arrangement coupled with the appliance. The snap-fit arrangement includes a first plurality of ears and a second plurality of ears, the first and second plurality of ears snap-fittingly engaging the plurality of holes.
