Abstract: The apparatus is a carrier tape reel assembly formed of two reel halves. The reel halves include hub portions which further include male detent elements which are rotationally symmetric with each other and likewise include female detent elements which are rotationally symmetric with each other. The male and female detent elements, however, include rotationally asymmetric elements to assure that the two halves are properly aligned so that the open tape slots of the two reel halves are properly aligned. The male and female detent elements are further engaged by a longitudinal motion, without the need for rotational movement during engagement. Stacking apertures are formed rotationally midway between adjacent detent elements to permit the stacking of reel halves, whereby the reel halves are facing in the same direction, but are rotated so that the male detent elements pass through the stacking apertures free of detent engagement.

Abstract: A bobbin for an electrical coil having a width that is small with respect to its depth. The bobbin is constructed from two identical halves, each having one generally flat flange and a web portion defining a latching feature, a locking feature and a core window centrally located in the flange. The mating surfaces of the two bobbin halves are defined along the distal ends of the web portions such that each half includes one complete flange and core window. The mating surfaces are also configured such as to prevent the fine coil wire from slipping between the mating surfaces of the two bobbin halves as the coil is being wound. The latching features of one bobbin half slidingly engage the latching features of the other bobbin half such that the two bobbin halves are held together. The locking features of the two bobbin halves also engage to prevent unintentional longitudinal movement between the two bobbin halves prior to winding the coil wire on the bobbin.
