Angular adjustable rear stud for molded case circuit breaker

Abstract

An adjustable rear stud connector is disclosed that is suitable for connecting a circuit breaker to a bus bar. Rear stud connectors are rotationally adjustable to contact a corresponding bus bar, while minimizing the stress applied to the rear stud connector when connected to the bus bar. The rear stud connector comprises a rear stud and a rear stud adapter. The rear stud comprises a stud blade and a stud base. The rear stud adapter comprises an adapter base and an adapter mount. The adapter base comprises a plurality of connector holes for connecting the stud base to the adapter base with fasteners. The stud base comprises a plurality of circumferentially extending slots with reference to a center axis of the stud base for connecting the stud base to the adapter base with fasteners and to allow for a degree of positional flexibility of the stud base relatively to the adapter base in a circumferential direction with respect to the center axis.

Description

technical field [0001] The present invention relates to an adjustable rear stud connector suitable for connecting a circuit breaker to a busbar. In particular, the present invention relates to an adjustable rear post connector that is rotatably adjusted to contact a corresponding busbar while minimizing stress applied to the rear post connector when connected to the busbar. Background technique [0002] In the current market, molded case circuit breakers (MCCBs) are often connected to the bus bars of appliances by means of breaker back post connectors, such as large copper and / or aluminum bus connections (bussing connector) or large cables. [0003] Conventional circuit breaker back post connectors have the disadvantage that the connection between the circuit breaker's back connector and the bus bars is often stressed due to poor alignment of the contact surfaces of the back connector and bus bars. Using fasteners to connect or secure the contact surfaces may increase stre...

[0003] Conventional circuit breaker rear post connectors have the disadvantage that the connection between the circuit breaker rear connector and the bus bars is often stressed due to poor alignment of the contact surfaces of the rear connector and bus bars

In the past, Siemens, as well as some competitors, offered adjustability of the rear post in 90 degree increments, often making it difficult to make a reliable connection without applying undesired forces to the unit
