ABSTRACT:
A miniature solenoid comprising an insulating bobbin, having upper and lower skirts, upon which magnet wire is wound to form a coil. The bobbin defines a central bore or passage for axial movement of an armature therein. The bobbin is fitted into a metallic can of magnetic permeable material. The ends of the coil extend below the lower skirt of the bobbin and are connected to external leads at this point. To protect the fragile connections, a spacing member is provided which has an annular boss which receives an extension of the bobbin core and projections thereon which engage the lower skirt of the bobbin and define a space between the spacing member and the bobbin. The spacing member has passages therethrough on either side thereof and on the underside has nipples defined thereon. The connecting wires extend through passages in the spacing member through the nipples which effectively spaces the leads apart. A closure member of generally annular outline and of magnetic material has slots in either side thereof which receive the nipples. The closure member provides a return flux path with the can.
