Abstract
The present invention provides a switch mechanism module and a line base module, useable separately or in combination, for an interior assembly of an electrical distribution device having a plurality of modules. The electrical distribution device has an enclosure with a handle external to the enclosure for operator control. The switch mechanism module and line base module include a modular housing having a generally planar base with upstanding side walls around the circumference of the base. The side walls have a top edge defining a mating surface. The modular housing is demountably secured to at least one adjacent module with a manually operated securement which is integrally formed with the modular housing.

A switch mechanism module for an interior assembly of an electrical distribution device having a plurality of modules, the electrical distribution device having an enclosure with a handle external to the enclosure for operator control, the switch mechanism module comprising:
- a modular housing having a generally planar first base with upstanding side walls around the circumference of the first base, the side walls having a top edge defining a mating surface, the modular housing having a generally planar second base with upstanding side walls having a top edge for abutting the mating surface of the first base;
- means for demountably fastening the first base to the second base, the fastening means being integrally formed with the first and second base;
- a shaft having two ends, the first end being adapted to connect with the handle external to the modular housing, the second end being adapted to connect to the adjacent module of the interior assembly through the modular housing;
- an operating mechanism being connected to the shaft and the first and second bases without discrete fasteners;
- and,
- means for demountably securing the housing to at least one adjacent module having a line base, the securing means being manually operated and integrally formed with the modular housing.
A line base module for an interior assembly of an electrical distribution device having a plurality of modules, the electrical distribution device having a fuse for each phase in a circuit, the line base module comprising:
- a modular housing having a generally planar base with upstanding side walls around the circumference of the base, the side walls having a top edge defining a mounting surface;
- a terminal for connecting to one end of the circuit for each phase, the terminal being fastened to the base;
- a fuse lug for connecting to the fuse on the opposite end of the circuit for each phase, the fuse lug being fastened to the base;
- a switch contact for opening and closing the circuit for each phase, the switch contact connected between the terminal and the fuse lug, the switch contact being fastened to the base;
- a rotor having two ends, one of the ends being adapted to connect with the adjacent module of the interior assembly, the rotor operatively connected to the switch contact of each phase, the rotor rotatably secured to the mounting surface of the side walls without discrete fasteners;
- and, means for demountably securing the housing to at least one adjacent module having a switch mechanism the securing means being manually operated and integrally formed with the modular housing.
An integrated module for a switch mechanism and line base of an interior assembly of an electrical distribution device having a plurality of modules, the electrical distribution device having an enclosure with a handle external to the enclosure for operator control and a fuse for each phase in a circuit, the integrated module comprising:
- a modular housing having a generally planar first, second, and third base, the first base having upstanding side walls around the circumference of the first base, the side walls having a top edge defining a mating surface, the second base having upstanding side walls with a top edge for abutting the mating surface of the first base, the third base having upstanding side walls around the circumference of the base, the side walls of the third base having a top edge defining a mounting surface, the first and third bases having a portion of their respective side walls integrally formed together so that the first and third bases are adjacent to each other:
- means for demountably fastening the first base to the second base, the fastening means being integrally formed with the first and second base;
- a shaft having two ends, the first end being adapted to connect with the handle external to the modular housing;
- an operating mechanism connected to the shaft and the first and second base without discrete fasteners;
- a terminal for connecting to one end of the circuit for each phase, the terminal being fastened to the base;
- a fuse lug for connecting to the fuse on the opposite end of the circuit for each phase, the fuse lug being fastened to the base;
- a switch contact for opening and closing the circuit for each phase, the switch contact connected between the terminal and the fuse lug, the switch contact being fastened to the base;
- and,
- a rotor having two ends, one of the ends connecting with the second end of the shaft through the portion of the first and third base side walls integrally formed together;
- the rotor being operatively connected to the switch contact of each phase, the rotor being rotatably secured to the mounting surface of the side walls without discrete fasteners.
