Abstract

A transfer assembly is for an electrical switching apparatus. The electrical switching apparatus has a first housing, separable contacts internal the first housing, and an operating handle having an ON position and an OFF position. The transfer assembly includes a rotary handle, a number of transfer components each structured to cooperate with the rotary handle, one of the transfer components being structured to engage the operating handle in order to allow the rotary handle to move the operating handle between the ON position and the OFF position, and a support assembly. The support assembly includes a second housing and a support member coupled to and located internal with respect to the second housing, the second housing being structured to be coupled to the first housing, the rotary handle being coupled to the second housing. Each of the transfer components is coupled to the support member.

First claim

What is claimed is:

1. A transfer assembly for an electrical switching apparatus, said electrical switching apparatus comprising a first housing, a pair of separable contacts disposed internal with respect to said first housing, and an operating handle having an ON position and an OFF position, the ON position corresponding to said separable contacts being closed, the OFF position corresponding to said separable contacts being open, said transfer assembly comprising:
a rotary handle;
a number of transfer components each structured to cooperate with said rotary handle, one of said transfer components being structured to engage said operating handle in order to allow said rotary handle to move said operating handle between the ON position and the OFF position; and
a support assembly comprising a second housing and a support member coupled to and disposed internal with respect to said second housing, said second housing being structured to be coupled to said first housing, said rotary handle being coupled to said second housing,
wherein each of said transfer components is coupled to said support member,
wherein said support member and said second housing are separate and distinct components,
wherein said one of said transfer components is a sliding member; and wherein said support assembly further comprises a number of coupling members extending through said support member and at least partially into said sliding member in order to couple said sliding member to said support member, and
wherein said support member comprises a first wall, a second wall disposed opposite and generally parallel to said first wall, and a third wall extending between and being disposed generally perpendicular to said first wall and said second wall; and wherein said coupling members extend through said third wall.

2. The transfer assembly of claim 1 wherein said first wall and said second wall each engage and are substantially flush with a corresponding wall of said second housing.

3. The transfer assembly of claim 1 wherein each of said transfer components is structured to move in a plane parallel to said third wall.

4. The transfer assembly of claim 1 wherein each of said transfer components is spaced from said first wall and said second wall.

5. The transfer assembly of claim 1 wherein said support member is made of a metallic material; and wherein said second housing is made of a non-metallic material.

6. The transfer assembly of claim 1 wherein said support assembly further comprises a number of coupling members extending at least partially through said second housing and said support member in order to couple said support member to said second housing.

7. The transfer assembly of claim 1 wherein said one of said transfer components is a sliding member; wherein said number of transfer components comprises a first gear member and a second gear member cooperating with said first gear member; wherein said first gear member is coupled to and is structured to be rotated by said rotary handle; and wherein said second gear member engages said first gear member and said sliding member in order to translate rotational movement of said rotary handle into linear movement of said sliding member.

8. A transfer assembly for an electrical switching apparatus, said electrical switching apparatus comprising a first housing, a pair of separable contacts disposed internal with respect to said first housing, and an operating handle having an ON position and an OFF position, the ON position corresponding to said separable contacts being closed, the OFF position corresponding to said separable contacts being open, said transfer assembly comprising:
a rotary handle;
a number of transfer components each structured to cooperate with said rotary handle, one of said transfer components being structured to engage said operating handle in order to allow said rotary handle to move said operating handle between the ON position and the OFF position; and
a support assembly comprising a second housing and a support member coupled to and disposed internal with respect to said second housing, said second housing being structured to be coupled to said first housing, said rotary handle being coupled to said second housing,
wherein each of said transfer components is coupled to said support member, and
wherein said support member comprises a first wall, a second wall disposed opposite and generally parallel to said first wall, and a third wall extending between and being disposed generally perpendicular to said first wall and said second wall; wherein each of said first wall and said second wall engages and is generally flush with a corresponding wall of said second housing; and wherein said one of said transfer components is disposed at or about said first wall, and opposite and distal said second wall.

9. The transfer assembly of claim 8 wherein said third wall has an elongated slot at or about a junction with said first wall; and wherein said support assembly further comprises a number of coupling members extending through the elongated slot and at least partially into said one of said transfer components.

10. An electrical switching apparatus comprising:
a first housing;
a pair of separable contacts disposed internal with respect to said first housing;
an operating handle having an ON position and an OFF position, the ON position corresponding to said separable contacts being closed, the OFF position corresponding to said separable contacts being open; and
a transfer assembly comprising:
a rotary handle,
a number of transfer components each structured to cooperate with said rotary handle, one of said transfer components being structured to engage said operating handle in order to allow said rotary handle to move said operating handle between the ON position and the OFF position, and
a support assembly comprising a second housing and a support member coupled to and disposed internal with respect to said second housing, said second housing being structured to be coupled to said first housing, said rotary handle being coupled to said second housing,
wherein each of said transfer components is coupled to said support member,
wherein said support member and said second housing are separate and distinct components,
wherein said one of said transfer components is a sliding member; and
wherein said support assembly further comprises a number of coupling members extending through said support member and at least partially into said sliding member in order to couple said sliding member to said support member, and
wherein said support member comprises a first wall, a second wall disposed opposite and generally parallel to said first wall, and a third wall extending between and being disposed generally perpendicular to said first wall and said second wall; and wherein said coupling members extend through said third wall.

11. The electrical switching apparatus of claim 10 wherein each of said transfer components is structured to move in a plane parallel to said third wall.

12. The electrical switching apparatus of claim 10 wherein said support member is made of a metallic material; and wherein said second housing is made of a non-metallic material.

13. The electrical switching apparatus of claim 10 wherein said one of said transfer components is a sliding member; wherein said number of transfer components comprises a first gear member and a second gear member cooperating with said first gear member; wherein said first gear member is coupled to and is structured to be rotated by said rotary handle; and wherein said second gear member engages said first gear member and said sliding member in order
