Abstract
The invention relates to an inductive component, having a coil (3) disposed in an injection molded housing (2) and having conductor rails (4), also mounted in the housing (2), to each of which the ends of the coil wires are contacted in the form of connection wires (7). Each of the connection wires (7) between the coil (3) and the respective conductor rail (4) forms one composite structure, comprising windings and twists, with a film (8) located between and/or outside them. The injection molding compound of the housing (2) can be applied directly to these composite structures. Preferably, the composite structure comprises at least two windings, which are twisted together and are disposed in the direction of the course of the connection wires (7).
Claims5
An inductive component, having
- a coil (3), disposed in an injection molded housing (2), and having conductor rails (4), also mounted in the housing (2), to which conductor rails the ends of the coil wires are each contacted, in the form of connection wires (7), characterized in that
- the connection wires (7) between the coil (3) and the respective conductor rail (4) each form one composite structure, comprising windings and twists, with a film (8) located between them and/or outside of them, and that
- the injection molding compound of the housing (2) can be applied directly to these composite structures.
The inductive component of one of the foregoing claims, characterized in that
- the inductive component is an inductive sensor, in which the coil (3) is applied to a magnet core, at one pole pin of which a change in magnetic field is detectable by means of metal parts moved past it on the outside, and that
- with the conductor rails (4), an electrical signal can be carried from the coil (3) to terminals of a contact array (5) in the housing (2) of the component.
A method for producing an inductive component of one of the foregoing claims, characterized in that
- the connection wires (7) of the coil (3) are wound onto arbors (9, 10) in order to produce the windings of the composite structure;
- that
- at least between two windings the film (8) is placed;
- and that
- subsequently, the windings of the connection wires (7) are twisted, incorporating the film (8) among them.
