ELECTRICAL COIL ASSEMBLY ABSTRACT An electrical coil assembly includes a bobbin having a pair of generally parallel end plates with a pair of terminals inserted into holes in an edge of one of the end plates. Magnet wire is wrapped around one of the terminals and then wound around the bobbin, with the finish end of the magnet wire being wrapped around the other terminal. A layer of protective insulated tape is applied over the surface of the wound coil and the terminals are dip soldered to the magnet wire. Formed integrally with the bobbin is an upstanding wall mounted on one of the end plates and having a lead wire receiv- ing slot formed therein. A cover member is formed on the other end plate and is connected thereto by a living hinge. Lead wires are soldered to the terminals and in- serted in the slot. The cover member is then folded over to mate with the wall so as to cover the terminals and the solder connections. The cover member is formed with a rib which is forced between the lead wires to aid in holding them securely and the cover member is then secured to the wall.
