Abstract

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.

First claim

What is claimed is:

1. An electrical switching apparatus comprising a housing and at least one connector assembly, the housing having a front portion and a rear portion, the rear portion having a plurality of walls that form an inner cavity and an outer surface, and one or more accessory components enclosed inside of the housing, each of the one or more accessory components including at least one accessory connection wire having a first end and an opposite second end, the first end of the at least one accessory connection wire being coupled to the one or more accessory components, said at least one connector assembly comprising:
an elongated member having a first end and an opposite second end, and an elongated portion disposed there between having a face surface and a back surface;
one or more apertures formed in the elongated portion extending horizontally there through in between the face surface and the back surface; and
one or more connectors correspondingly positioned within the one or more apertures, each having one end extending outwardly from the back surface of the elongated portion and adapted to correspondingly engage the second end of the at least one accessory connection wire, and each said one or more connectors having an opposite other end extending outwardly from the face surface of the elongated portion and adapted to correspondingly engage one or more wires from user equipment located outside of the housing
wherein each of said one or more connectors mechanically and electrically connects each of the at least one accessory connection wire with each of the one or more user equipment wires, and
wherein the at least one connector assembly is installed such that the face surface of the elongated portion is flush with the outer surface of the housing.

2. The connector assembly of claim 1 , wherein the elongated member extends through one of said plurality of walls of the rear portion and the elongated member is coupled to the rear portion.

3. The connector assembly of claim 2 , wherein said plurality of walls comprises a first side wall, a second side wall positioned opposite the first side wall, a first end wall, a second end wall positioned opposite the first end wall and a back wall.

4. The connector assembly of claim 3 , wherein the elongated member extends through a preformed slot in one of the first side wall, the second side wall, and the back wall.

5. The connector assembly of claim 4 , wherein a second elongated member extends through one of the first side wall, the second side wall, the first end wall, the second end wall and the back wall.

6. The connector assembly of claim 1 , wherein the electrical switching apparatus is a molded case circuit breaker.

7. The connector assembly of claim 1 , wherein the one or more accessory components is selected from the group consisting of shunt trips, under-voltage releases, auxiliary contacts and bell alarm contacts.

8. A connector assembly for an electrical switching apparatus, said electrical switching apparatus comprising a housing having a front portion and a rear portion, the rear portion having a plurality of walls that form an inner cavity and an outer surface, and one or more accessory components enclosed by the housing, each of the one or more accessory components including at least one accessory connection wire having a first end and an opposite second end, the first end of the at least one accessory connection wire being coupled to the one or more accessory components, said connector assembly comprising:
an elongated member having a first end and an opposite second end, and an elongated portion disposed there between;
one or more connectors extending outwardly from a first surface of the elongated member and adapted to engage the second end of the at least one accessory connection wire;
one or more apertures extending horizontally through the elongated member and aligning with the one or more connectors, the one or more apertures adapted to receive one or more wires from user equipment; and
a plug-in mate, comprising:
an extension member having a first end and an opposite second end, and an elongated portion disposed there between;
one or more extension connectors extending outwardly from a first surface of the extension member and adapted to engage the corresponding one or more apertures of the elongated member of the connector assembly; and
one or more extension apertures extending horizontally through the extension member and aligning with the one or more extension connectors, the one or more extension apertures adapted to receive the one or more wires from the user equipment.

9. The connector assembly of claim 8 , wherein the plug-in mate is structured to connect to the elongated member of the connector assembly and the extension member of the plug-in mate extends outwardly perpendicular from the first surface of the elongated member.

10. The connector assembly of claim 8 , wherein the plug-in mate has a right-angle shape.

11. The electrical switching apparatus of claim 1 , wherein the at least one connector assembly comprises a first connector assembly and a second connector assembly, each of which extends into one of the plurality of walls.

12. The electrical switching apparatus of claim 11 , wherein the first connector assembly extends into one of the plurality of walls and the second connector assembly extends into a second, different one of the plurality of walls.
