Abstract
A bobbin for an electrical coil is described having a main winding space for electrical wire and at least two separate further winding spaces for terminating the wire wound on the main winding space. The or each further winding space has a groove in which a number of terminating wire coils can be wrapped. The groove is breached or gapped so that the wire coils wrapped in the channel bridge the breach and can be wholly or partially soldered together at the bridging portions to form terminal connections to the wire on the main winding space.
