Abstract
A motor start capacitor assembly for providing an enclosure for a motor start capacitor and a thermistor electrically connected in series. The enclosure is constructed of a low temperature plastic case and cap with a high temperature plastic core for supporting the thermistor within the low temperature plastic case. The core holds the thermistor in a longitudinal orientation. The core and thermistor and related contacts are assembled without rivets or other fasteners.
Claims9
A motor start capacitor assembly comprising:
- a. a capacitor having a first end, a second end, a transverse capacitor dimension, a longitudinal capacitor dimension, and a first terminal and a second terminal at the first end of the capacitor;
- b. a capacitor enclosure comprising:
- i. a plastic case having a closed end, an open end, a transverse case dimension, and a longitudinal case dimension, wherein the transverse case dimension is greater than the transverse capacitor dimension to accommodate insertion of the capacitor into the case, and the longitudinal case dimension is greater than the longitudinal capacitor dimension;
- ii. a plastic cap dimensioned to engage the open end of the case;
- and
- c. a core assembly positioned within the case between the first end of the capacitor and the plastic cap, wherein the core assembly comprises:
- i. a plastic core having a plurality of interconnected ribs extending in the longitudinal direction of the case which ribs form at least one chamber with its shortest dimension extending in the transverse direction of the case;
- ii. a thermistor having
- (a) a long dimension and a thickness dimension and positioned in the chamber with the thickness dimension of the thermistor coinciding with the shortest dimension of the chamber;
- (b) first and second thermistor terminals;
- and
- iii. a first connector for connecting the first terminal of the capacitor to the first thermistor terminal
- iv. a second connector connected to the second thermistor terminal.
