example 1

[0036] image 3 The rear of the plug-in circuit breaker panel 2 is shown comprising a first feeder 30 and a second feeder 32 for a three-phase system. Typically, for each feeder 30, 32, there may be a single three-pole AC breaker (not shown) and multiple single-pole AC breakers (not shown) for each of the three phases. For example, each feeder 30, 32 is a three-terminal junction box with three power terminals for the three phases of the corresponding feeder. The first surface 34 of the electrical bus structure 6 ( figure 2 ) close to the first plurality of plug-in parts 8 and the feeders 30 , 32 and their power terminals together with the plurality of load connectors 38 , 40 are coupled to the opposite second surface 36 . Thus, the load connectors 38 , 40 include load outputs (eg, loads) from corresponding circuit breakers 10 associated with the respective feeders 30 , 32 . In a similar manner, the power input (eg line) to the corresponding circuit breaker 10 is associated...

[0041] Figure 5 A circuit breaker 10 in a plug-in circuit breaker panel 2 is shown. Each of the plurality of first insertion parts 8 is a plurality of male terminals, and the second insertion part 16 is a plurality of female sockets. Alternatively, any suitable blade-to-fuse type or banana plug type connections may be used. The circuit breaker 10 can be easily swapped out using these plug-in parts 8 , 16 . The use of linear motion (eg, plug-in) circuit breaker pins and receptacles and faceplate 18 eliminates the threaded sleeves, nuts, washers, lock washers and terminal screws that would otherwise be employed with known aircraft circuit breakers. As a result, circuit breaker maintenance can be performed, for example and without limitation, in less than about 5 minutes, compared to hours with prior art methods. The breaker panel 2 remains fixed to the aircraft (not shown), thereby reducing moving parts and shortening the harness length for access. This also reduces point-t...

example 3

[0043] see Image 6 , another plug-in breaker panel 50 comprising a housing (not shown, but see figure 1 The housing 4) and the electrical bus structure 51, the electrical bus structure can be used with figure 1 The same or similar electrical bus structure. A first surface 52 of the panel 54 includes an illuminated legend 56 for a portion of a plurality of circuit breakers 58 . LED illuminated marking strip 60 may identify a corresponding circuit breaker (eg, 58 ) and a corresponding power circuit or load (not shown). The marking strip 60 can be configured to be easily removed and reconstituted in about 5 minutes.

Abstract

A circuit breaker assembly includes a housing, an electrical bus structure coupled to the housing, and a number of first plug-in members coupled to the electrical bus structure. A number of circuit breakers include a first surface and a second plug-in member disposed opposite the first surface. The second plug-in member of each of the number of circuit breakers is mated with a corresponding one of the number of first plug-in members. A plate member is removably coupled to the housing. The plate member includes a first surface and an opposite second surface. The first surface of the number of circuit breakers engages the opposite second surface of the plate member in order to maintain mating of each of the number of circuit breakers with the corresponding one of the number of first plug-in members.

Description

technical field [0001] The concepts disclosed herein relate generally to circuit breakers, and more particularly to circuit breaker assemblies, such as circuit breaker panels for many circuit breakers. Background technique [0002] Circuit breakers are used, for example, in aircraft electrical systems not only to provide overcurrent protection but also as switches for switching devices on and off. Aircraft or subminiature circuit breakers, for example, are typically smaller to accommodate higher density layouts of aircraft circuit breaker panels that provide user access to circuit breakers for many circuits. An aircraft electrical system may, for example, consist of hundreds of circuit breakers, each for circuit protection functions and circuit disconnection functions by push-pull handles. [0003] The push-pull handle of the circuit breaker moves from the inside to the outside to disconnect the corresponding load circuit. This action can be manual, or automatic in the eve...
