Kind Code:
A1
Abstract:
[Problem] To provide a solenoid with which, when attaching a core to a yoke, the core can be simply and robustly attached using an inexpensive, small, and general-purpose handheld tool without swaging using a large press. [Solution] A solenoid 1 of the present invention comprises: a yoke 2 having a U-shaped cross section; a bobbin 3 having an electromagnetic coil 4 disposed in the yoke 2; a fixed core 5 disposed in the bobbin 3; and a flapper 6 pivotally mounted to the yoke 2. The fixed core 5 and a bottom surface of the yoke 2 are integrally linked by means of threaded engagement. Thus, the fixed core 5 can be mounted to the bottom surface of the yoke 2 simply, using a general-purpose, inexpensive, and small handheld tool (such as a hand drill or an electric screwdriver) without requiring a large working area for swaging as according to prior art.
