Abstract

A circuit breaker assembly includes a circuit breaker cassette having a connector receiving zone, and a housing receptive of the circuit breaker cassette. The housing includes a connector mounting member. A circuit breaker connector member snap-fittingly extends into the connector receiving zone through the connector mounting member joining the circuit breaker cassette and the housing.

First claim

What is claimed is:

1. A circuit breaker assembly comprising:
a circuit breaker cassette including a connector receiving zone defined therein;
a housing including a circuit breaker cassette receiving portion defined therein, the circuit breaker cassette receiving portion receptive of the circuit breaker cassette and defining a connector passage therethrough; and
a circuit breaker connector member snap-fittingly extending into the connector receiving zone through the connector passage to secure the circuit breaker cassette to the circuit breaker cassette receiving portion of the housing, wherein the circuit breaker connector member includes at least one locking arm member engaging the housing.

2. The circuit breaker assembly according to claim 1 ,
wherein the connector passage is substantially aligned with the connector receiving zone.

3. The circuit breaker assembly according to claim 1 , wherein the at least one locking arm member comprises an elastically deformable arm member.

4. The circuit breaker assembly according to claim 1 , wherein the circuit breaker connector member is non-conductive to electricity.

5. The circuit breaker assembly according to claim 1 , wherein the circuit breaker connector member includes a first portion, a second portion, and a connecting portion, the connecting portion defining an elastically deformable hinge.

6. The circuit breaker assembly according to claim 1 , wherein the connector receiving zone defines an exhaust duct configured to direct gases from the circuit breaker cassette.

7. The circuit breaker assembly according to claim 6 , wherein the circuit breaker connector member includes an angled surface portion extending into the exhaust duct, the angled surface portion being configured and disposed to channel exhaust gases passing from the exhaust duct in a desired direction.

8. The circuit breaker assembly according to claim 1 , wherein the circuit breaker connector member is formed from plastic.

9. A circuit breaker assembly comprising:
a plurality of circuit breaker cassettes, each of the plurality of circuit breaker cassettes including a respective connector receiving zone therein;
a housing including a circuit breaker cassette receiving portion defined therein, the circuit breaker cassette receiving portion receptive of the plurality of circuit breaker cassettes and defining a plurality of connector passages therethrough, each connector passage corresponding to a respective one of the plurality of circuit breaker cassettes; and
one or more circuit breaker connector members snap-fittingly extending into one or more of the connector receiving zones through one or more connector passages to secure the plurality of circuit breaker cassettes to the circuit breaker cassette receiving portion of the housing, wherein each of the one or more circuit breaker connector members includes a first portion, a second portion, and a connecting portion, the connecting portion defining an elastically deformable hinge.

10. The circuit breaker assembly according to claim 9 , wherein each connector passage is substantially aligned with the connector receiving zone.

11. The circuit breaker assembly according to claim 10 , wherein each of the one or more circuit breaker connector members includes at least one locking arm member engaging the housing.

12. The circuit breaker assembly according to claim 11 , wherein the at least one locking arm member comprises an elastically deformable arm member.

13. The circuit breaker assembly according to claim 9 , wherein each of the one or more circuit breaker connector members is non-conductive to electricity.

14. The circuit breaker assembly according to claim 9 , wherein each connector receiving zone defines an exhaust duct configured to direct gases from the corresponding circuit breaker cassette.

15. The circuit breaker assembly according to claim 14 , wherein each of the one or more circuit breaker connector members includes an angled surface portion extending into the exhaust duct, the angled surface portion being configured and disposed to channel exhaust gases passing from the exhaust duct in a desired direction.

16. The circuit breaker assembly according to claim 9 , wherein each of the one or more circuit breaker connector members is formed from plastic.

17. The circuit breaker assembly according to claim 9 , wherein the plurality of circuit breaker cassettes including at least three circuit breaker cassettes mounted in the housing.

18. The circuit breaker assembly according to claim 9 , wherein the plurality of circuit breaker cassettes are operatively connected.

19. A method of assembling a circuit breaker comprising:
installing at least one circuit breaker cassette having a connector receiving zone defined therein into a cassette receiving portion of a housing of the circuit breaker; and
snap-fittingly inserting at least one circuit breaker connector member through at least one connector passage into the connector receiving zone to establish a preload on the connector receiving zone to provide a biasing force that secures the at least one circuit breaker cassette to the cassette receiving portion of the housing.

20. The method of claim 19 , wherein installing the at least one circuit breaker cassette into the cassette receiving portion includes installing a plurality of circuit breaker cassettes into the cassette receiving portion.

21. The method of claim 20 , wherein snap-fittingly inserting the at least one circuit breaker connector member includes snap-fittingly inserting the at least one circuit breaker connector member between the cassette receiving portion of the housing and one or more of the plurality of circuit breaker cassettes.
