Claims19
An electromagnet comprising:
- a pre-assembly unit comprising a guide element and a coil;
- an armature which is arranged translationally displaceable in the guide element;
- and
- a core comprising an axially extending annular protrusion into which the pre-assembly unit is inserted,
- wherein,
- the guide element comprises a sleeve and a mounting protrusion which extends radially from an outer peripheral surface of the sleeve,
- the sleeve comprises an inner circumferential surface which is configured to directly guide the axially movable armature,
- the mounting protrusion is attached to the axially extending annular protrusion of the core
- the pre-assembly unit further comprises a cover and a plug which is electrically connected to the coil,
- the cover is fixed to the guide element,
- the guide element is interlockingly fastened to the cover,
- the guide element comprises a protrusion which extends axially to the cover,
- the cover comprises a protrusion which extends axially to the guide element, and
- the protrusion of the guide element and the protrusion of the cover interlock with each other.
