COIL CARRIER AND ELECTROMAGNETIC ACTUATOR HAVING A COIL CARRIER |
| 摘要 |
A coil carrier for an electromagnetic actuator (2), with a winding section (3) for the accommodation of an energisable winding, with an injection moulded plastic body (4), with a first yoke disc (8) designed as an annular disc and affixed on a first axial face of the winding section (3), and with an armature guide chamber enclosed by the plastic body (4) for the accommodation of an axially adjustable armature (32), wherein a second yoke disc (16) is provided on an axial face of the winding section (3) that is located opposite to the first axial face, characterised in that the first yoke disc (8) has at least one recess (24) that is open in the radially inwards direction, and in that the first yoke disc (8) is affixed to the plastic body (4) by means of overmoulding, such that plastic body material projects radially inwards beyond the recess (24) and forms a guide (12) for the armature (32), and in that the second yoke disc (16) is affixed to the plastic body (4) by means of overmoulding. |

1. A coil carrier for an electromagnetic actuator (2), with a winding section (3) for the accommodation of an energisable winding, with an injection moulded plastic body (4), with a first yoke disc (8) designed as an annular disc and affixed on a first axial face of the winding section (3), and with an armature guide chamber enclosed by the plastic body (4) for the accommodation of an axially adjustable armature (32), wherein a second yoke disc (16) is provided on an axial face of the winding section (3) that is located opposite to the first axial face,
the first yoke disc (8) has at least one recess (24) that is open in the radially inwards direction, and wherein the first yoke disc (8) is affixed to the plastic body (4) by means of overmoulding, such that plastic body material projects radially inwards beyond the recess (24) and forms a guide (12) for the armature (32), and wherein the second yoke disc (16) is affixed to the plastic body (4) by means of overmoulding. |
