Housing for movement sensor with protective cover for components
View Patent ↗The invention relates to a device for detecting the movement of a movable component, the device having an inner part 1 and the inner part 1 having a housing in which are mounted conductors 3 that carry electrical components 4 and a sensor element. One end of each conductor 3 protrudes from the inner part 1 forming plug contacts 6 , and the inner part 1 is encapsulated by a plastic housing 2 in such a way that the plug contacts 6 project into a plug receiver 5 in the plastic housing. The electrical components 4 and the sensor element are covered by covers and encapsulated by the plastic housing 2 . The covers protect the components from the plastic in the encapsulation process.
1. A device for detecting movement of a movable component, said device comprising:
an inner part encapsulated by injection-molding or casting a housing with at least one chamber and a plug socket;
at least one conductor disposed in said housing and bearing an electrical component and a sensor element, said electrical component and said sensor each being disposed in said at least one chamber, said at least one conductor having an end protruding from said plug socket of said inner part to form a plug contact; and
a cap closing the at least one chamber and having an outer contour corresponding to an outer contour of said inner part surrounding said at least one chamber, wherein said cap and the inner part are plastic and said cap is connected to said inner part by a film hinge.
2. The device of claim 1 , wherein said cap is held in an installation position on said inner part by a latching connection.
3. The device of claim 1 , wherein said at least one conductor is formed by a metal stamping and each of said electrical component and said sensor element is welded or soldered to said at least one conductor.
4. The device of claim 1 , wherein said sensor element comprises a Hall element and is disposed at an end of said at least one conductor that is opposite from the end forming said plug contact.
