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. The latching features are configured such that winding of the coil wire about the bobbin web positively interlocks the latches, thereby preventing them from being separated.
