Abstract

A transmission assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, a mount, at least one charging mechanism, and a pair of separable contacts. The transmission assembly has a drive assembly and a transfer assembly. The drive assembly includes a rotary driving member, a stored energy mechanism. and a linear driving member partially extending into the stored energy mechanism and being coupled to the rotary driving member. The transfer assembly cooperates with the drive assembly and the separable contacts and includes a sliding transfer component. The transmission assembly moves between a LOADED OPEN position, an UNLOADED CLOSED position, a LOADED CLOSED position, and an UNLOADED OPEN position. When the transmission assembly moves from the LOADED OPEN position to the UNLOADED CLOSED position, the linear driving member drives the sliding transfer component in a generally linear direction, thereby closing the separable contacts.

Dependent claims

A transmission assembly for an electrical switching apparatus, said electrical switching apparatus comprising a housing, a mount coupled to said housing, at least one charging mechanism coupled to said mount, and a pair of separable contacts disposed within said housing, said transmission assembly comprising:

a drive assembly comprising:
a rotary driving member structured to be coupled to said at least one charging mechanism,
a stored energy mechanism, and
a linear driving member partially extending into said stored energy mechanism and being coupled to said rotary driving member,
a transfer assembly cooperating with said drive assembly and structured to cooperate with said separable contacts, said transfer assembly comprising a sliding transfer component structured to be disposed on said mount,
wherein said transmission assembly is structured to move between a LOADED OPEN position, an UNLOADED CLOSED position, a LOADED CLOSED position, and an UNLOADED OPEN position, and
wherein, when said transmission assembly moves from the LOADED OPEN position to the UNLOADED CLOSED position, said linear driving member drives said sliding transfer component in a generally linear direction, thereby closing said separable contacts.
