Abstract
Abstract A relay center is provided for control with lower voltage control circuits of higher voltage power supply circuits. The relay center has a two level partition detachably mounted in a dimensionally conforming metal box. The first or rear level of the partition serves to position and retain relays extending through the partition between a high voltage and a low voltage side. The second or upper level is equipped with a terminal bar permitting highly visible, easily accessible, low voltage wiring of the relays.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A relay center, said relay center comprising an elongated partition of conductive material having a laterally extending base and means for detachably mounting said partition into a housing to divide said housing into high voltage and low voltage compartments, a shelf extending laterally from said partition and overlying said base, a terminal strip having a first set of spaced-apart terminals and a second set of spaced-apart terminals thereon, said terminal strip mounted in insulated relation on said shelf, a plurality of spaced-apart relay openings beneath said sHelf and above said base, a bus bar having terminal screws thereon mounted in insulated relation to said shelf and extending at least partly along said shelf in spaced relation to said terminal strip, a plurality of relays, each of said relays being mounted in a respective one of said relay openings, each of said relays having a low voltage portion pre-wired to said first set of terminals, said second set of terminals being available for connection of control wires thereto without disturbing the pre-wired connections to said first set of terminals.
Claim 2
Dependent Claim
178 words
A relay center, said relay center comprising an elongated partition of conductive material having a laterally extending base and means for detachably mounting said partition into a housing to divide said housing into high voltage and low voltage compartments, a shelf extending laterally from said partition and overlying said base, a terminal strip having a first set of spaced-apart terminals and a second set of spaced-apart terminals thereon, said terminal strip mounted in insulated relation on said shelf, a plurality of spaced-apart relay openings beneath said sHelf and above said base, a bus bar having terminal screws thereon mounted in insulated relation to said shelf and extending at least partly along said shelf in spaced relation to said terminal strip, a plurality of relays, each of said relays being mounted in a respective one of said relay openings, each of said relays having a low voltage portion pre-wired to said first set of terminals, said second set of terminals being available for connection of control wires thereto without disturbing the pre-wired connections to said first set of terminals.
Claim 3
Dependent Claim
23 words
The relay assembly of claim 1 wherein said partition has a low voltage side and said shelf extend from said low voltage side.
Claim 4
Dependent Claim
55 words
The relay assembly of claim 2 wherein said mounting means comprises slots in said base non-symmetrically positioned with respect to the length of said base for ensuring that said partition can be mountd in said housing only in a position wherein said low voltage side of said partition is disposed in said low voltage compartment.
