More Information
Summary:A solenoid coil includes a coil winding that generates an electromagnetic force when a current is supplied to the coil winding. The solenoid coil also includes an electrically insulative bobbin made of an insulating material having a melting point. The bobbin includes a spool for supporting the coil winding. The spool includes a first end and a second end opposite the first end. The coil winding is positioned between the first end and the second end. The bobbin also includes a flange connected to one of the first end and the second end. A continuous ridge extends from the flange between an outer edge and studs to form a moisture barrier. The solenoid coil further includes an overmold enclosing at least a portion of the bobbin and the coil winding. The overmold bonds to the continuous ridge when the solenoid coil is heated to a temperature above the melting point.
