Abstract
A coil assembly includes a spool (102) having an upper flange (104), a medial flange (106) and a lower flange (108). A terminal groove (118) is established between the upper flange (104) and the medial flange (106), and a winding bay (110) is established between the medial flange (106) and the lower flange (108). Ramps (130) are formed in the groove (118) and at least two terminal posts (126), each having a foot (128), are inserted through the upper flange such that each foot (128) is disposed within the groove (118). Each terminal post (126) is movable between a winding position, wherein the foot (128) protrudes outwardly to facilitate engaging a coil wire end (132), and a retracted position, wherein the foot (128) is retracted behind the respective ramp (130).
