Abstract:
An electromagnetic device comprising:a solenoid including: a body formed of a non-magnetic material for providing a path to a magnetic field having a closed curved surface, a first surface outside of a space around said closed curved surface and a second surface outside of said space and said first surface and projecting from both major surfaces of a yoke so that said second surface is on one of said major surfaces of said yoke, said yoke being formed with a hole open to said both major surfaces, conductive pins partially embedded in said body and having respective first end portions projecting from said first surface and respective second end portions projecting from said second surface into said hole, and a coil formed on said closed curved surface so as to occupy said space and having both end portions electrically connected to said first end portions, respectively, an electric connector including: a socket holder associated with said conductive pins and having a guard portion passing through said hole, projecting from said both surfaces of said yoke for preventing said first end portions and said second end portions from damage and a hook projecting from said guard portion in a direction parallel to said second end portions and a socket connected to a cable, pushed into and pulled out from said socket holder for electrically connecting said cable to and disconnecting said cable from said coil and having holes, said hook keeping said socket in said socket holder when said socket is pushed into said socket holder, and a member electromagnetically influenced in said magnetic field so as to give rise to relative motion between said solenoid and said member, wherein said second end portions of said conductive pins are inserted into said holes so as to be electrically connected to said cable when said socket is pushed into said socket holder.
