  • Patent number: 5821840
    Abstract: A simplified solenoid assembly has a simplified construction that maintains the mechanical integrity and operating efficiency of the solenoid. The solenoid assembly includes a frame having first and second frame leg portions extending from a frame middle portion. The side region of the first frame leg portion includes an aperture, and the side region of the second frame leg portion defines a frame pole face generally opposite the aperture. A bobbin having first and second bobbin end portions and a generally cylindrical bobbin intermediate portion is "snap-fit" between the frame leg portions. A plunger receiving region formed in the bobbin is aligned with the aperture through the frame, and the second bobbin end portion extends across the plunger receiving region to form a fixed gap between the bobbin and the frame. A plunger is slidably received through the aperture in the frame and into the plunger receiving region within the bobbin.
