Definitions
- Figure 1 is an exploded perspective view of the thermal- magnetic trip portion of the prior art
- Figure 6 is an exploded perspective view of an alternate embodiment of the thermal-magnetic trip mechanism of the present invention.
- Figure 7 is a side elevational view of the thermal-magnetic trip mechanism of Figure 6;
- Circuit breaker 20 includes a pair of rotary contacts 34, 36, disposed on opposite ends of rotating contact arm 38.
- the rotary contacts 34, 36 are in opposing alignment to fixed contacts 40, 42 respectively.
- the rotating contact arm is mounted pivotally to the circuit breaker frame at 48.
- the rotating contact arm 38 engages a circuit breaker operating mechanism at a pair of pivotal engagements 44,46 that are interposed between the rotating contacts.
- Bimetalhc strip 88 is generally rectangular having substantially the same width as the heater element 108, both being sized to be dispositioned between the arms 152, 154 of the yoke 150 (to be described hereinafter).
- An upper end 94 of the bimetallic strip 88 extends above the heater element 108 for engaging the operating mechanism 20 as described hereinbefore.
- the bimetalhc strip 88 disengages a lever 52 connected to a trip latch 66 (See Figure 2) when the upper end 94 of the bimetalhc strip 88 bends in response with the heat generated by current in the heater element 108.
- the bimetalhc strip 88 is positioned approximate the heater element 108 and substantially in parallel opposition to the heater element.
- Each conductor 220 and the heater element 108 define a first plane of the heater device 96.
- Each conductor 220 includes a portion 228, that angularly steps inward towards the bimetalhc strip 88 and which defines a second planar surface, spaced a predetermined distance from the first planar surface.
- each L-shaped conductor 220 depends from portion 228 and is dispositioned facing the opposing lower portion thereof. With the bimetalhc strip 88 attached to the lower portions 230, the space 232 between the bimetallic strip 88 and the heater element 108 is formed.
- the bimetallic strip 88 comprises at least two metals as substantially described hereinabove.
- a lower portion 126 of the bimetalhc strip 88 depends from the upper portion 128 of the bimetalhc strip 88 and is substantially wider than the upper portion.
- a tack weld 130, 132 attaches the lower portion 126 of the bimetalhc strip 88 to each L-shaped portion 230.
- fastening means well known in the art can describe the attachment e.g. rivets, pins and screws.
- the flux within each slot 224 is a sum of individual fluxes within each slot as described hereinbefore and the operation of this second embodiment is substantially as described with respect to the other embodiment hereinabove.
