Abstract

A board-mounted circuit breaker assembly for an electronic equipment enclosure includes a printed circuit board having a plurality of quick-connect terminals and a circuit breaker. The circuit breaker includes a housing and a plurality of quick-connect terminals that are at least partially recessed into a portion of the housing to reduce the overall “z”-height of the circuit breaker. The quick-connect terminals on the circuit breaker are adapted to mechanically and electrically connect to the quick-connect terminals on the printed circuit board.

Claims

1. A circuit breaker-equipped electronic equipment enclosure system, comprising:

an electronic equipment enclosure;

electronic equipment mounted within the electronic equipment enclosure; and

a board-mounted circuit breaker assembly mounted within the electronic equipment enclosure and utilized in relation to the electronic equipment, the board-mounted circuit breaker assembly including

a printed circuit board having a plurality of printed circuit board quick-connect terminals disposed on, and protruding away from, a mounting surface thereof, and

at least one circuit breaker having a housing body, with a rear surface facing the mounting surface, and a plurality of circuit breaker quick-connect terminals adapted to mechanically and electrically connect to the plurality of printed circuit board quick-connect terminals, each circuit breaker quick-connect terminal being entirely recessed, independently, in a respective one of a plurality of hollows of the housing body such that an outermost distal end of each circuit breaker quick-connect terminal does not extend beyond the rear surface;

wherein each of the printed circuit board quick-connect terminals is received within a respective one of the plurality of hollows of the housing body to electrically couple with the circuit breaker quick-connect terminal recessed therein, thereby reducing an overall height of the at least one circuit breaker above the mounting surface.

2. The circuit breaker-equipped electronic equipment enclosure system of claim 1, wherein the circuit breaker quick-connect terminals are male quick-connect terminals.

3. The circuit breaker-equipped electronic equipment enclosure system of claim 1, wherein the printed circuit board quick-connect terminals are female quick-connect terminals.

4. The circuit breaker-equipped electronic equipment enclosure system of claim 1, wherein the plurality of circuit breaker quick-connect terminals includes four circuit breaker quick-connect terminals.

5. The circuit breaker-equipped electronic equipment enclosure system of claim 4, wherein the four circuit breaker quick-connect terminals are arranged at ends of the housing body.

6. The circuit breaker-equipped electronic equipment enclosure system of claim 1, further comprising a cover extending over the at least one circuit breaker.

7. The circuit breaker-equipped electronic equipment enclosure system of claim 6, wherein the cover is positioned a distance from the printed circuit board by at least one spacer.

8. The circuit breaker-equipped electronic equipment enclosure system of claim 1, wherein each of the plurality of printed circuit board quick-connect terminals is disposed such that the housing body only partially surrounds the printed circuit board quick-connect terminals as viewed in a projected view of the rear surface of the housing body.

9. A board-mounted circuit breaker assembly for an electronic equipment enclosure, comprising:

a printed circuit board having a plurality of printed circuit board quick-connect terminals disposed on, and protruding away from, a mounting surface thereof; and

a circuit breaker including

a housing body having a rear surface facing the mounting surface of the printed circuit board, and

a plurality of circuit breaker quick-connect terminals adapted to mechanically and electrically connect to the printed circuit board quick-connect terminals, each of the plurality of circuit breaker quick-connect terminals being entirely recessed, independently, in a respective hollow of the housing body such that an outermost distal end of each circuit breaker quick-connect terminal does not extend beyond the rear surface.

10. The board-mounted circuit breaker assembly of claim 9, wherein the circuit breaker quick-connect terminals are male quick-connect terminals.

11. The board-mounted circuit breaker assembly of claim 9, wherein the printed circuit board quick-connect terminals are female quick-connect terminals.

12. The board-mounted circuit breaker assembly of claim 9, wherein the plurality of circuit breaker quick-connect terminals includes four circuit breaker quick-connect terminals.

13. The board-mounted circuit breaker assembly of claim 12, wherein the four circuit breaker quick-connect terminals are arranged at ends of the housing body.

14. The board-mounted circuit breaker assembly of claim 9, wherein each of the plurality of printed circuit board quick-connect terminals is disposed such that, when the circuit breaker is mounted to the printed circuit board, the housing body only partially surrounds the printed circuit board quick-connect terminals as viewed in a projected view of the rear surface of the housing body.

15. A method of installing circuit breakers on a printed circuit board for an electronic equipment enclosure, comprising:

providing at least one circuit breaker having a housing body, with a printed circuit board-facing surface, and a plurality of circuit breaker quick-connect terminals, each circuit breaker quick-connect terminal being entirely recessed, independently, in a respective one of a plurality of hollows of the housing body such that an outermost distal end of each circuit breaker quick-connect terminal does not extend beyond the printed circuit board-facing surface of the housing body; and

installing the at least one circuit breaker onto a printed circuit board, having a plurality of printed circuit board quick-connect terminals disposed on, and protruding away from, a mounting surface thereof, such that the act of coupling the circuit breaker quick-connect terminals to the printed circuit board quick-connect terminals both mechanically mounts the at least one circuit breaker on the printed circuit board and electrically connects the at least one circuit breaker inline to the printed circuit board;

wherein each of the printed circuit board quick-connect terminals is received within a respective one of the plurality of hollows of the housing body to electrically couple with the circuit breaker quick-connect terminal recessed therein, thereby reducing an overall height of the at least one circuit breaker above the mounting surface.

16. The method of claim 15, further comprising fastening a cover directly to the at least one circuit breaker with mechanical fasteners.

17. The method of claim 16, further comprising positioning the cover a distance from the printed circuit board with spacers, fastening the cover to the spacers, and fastening the spacers to the printed circuit board.

18. The method of claim 15, wherein the circuit breaker quick-connect terminals are male quick-connect terminals.

19. The method of claim 15, wherein the printed circuit board quick-connect terminals are female quick-connect terminals.

20. The method of claim 15, wherein each of the plurality of printed circuit board quick-connect terminals is disposed such that the housing body only partially surrounds the printed circuit board quick-connect terminals as viewed in a projected view of the printed circuit board-facing surface of the housing body.
