  • Patent number: 5423117
    Abstract: A method for fabricating a molded solenoid device which is encased in an insulating synthetic resin shell, in which a resilient sealing cover member of an electrically insulating material is fitted on each one of a couple of solenoid coil terminals which are projected from a solenoid coil bobbin. The sealing cover members on the respective coil terminals are brought into intimate contact with inner edges of coil terminal escape holes in a mold in which a solenoid assembly is to be molded, thereby forming tight seals around the coil terminals in the coil terminal escape holes while a molten synthetic resin material is being introduced into the mold cavity around the solenoid assembly.
