Abstract

In an electrical appliance having a housing, a cable bushing projects through a recess in the housing, a cable is passed through the cable bushing, a printed circuit board including a luminous device is surrounded by the housing, the cable bushing is made of a transparent material, and the luminous device is adapted to project light into the cable bushing.

First claim

The invention claimed is:

1. An electrical appliance, comprising:
a housing;
a printed circuit board including an illumination device surrounded by the housing;
a cable bushing projecting through a recess in the housing and formed of a transparent material; and
a cable passing through the cable bushing;
wherein the cable bushing is elastically deformed such that a material of the cable bushing presses and/or seals towards the housing, and the cable bushing is elastically deformed such that the material of the cable bushing presses and/or seals towards the cable.

2. The electrical appliance according to claim 1 , wherein the cable bushing has a first region and a second region, the first region having a cylindrical outer circumference and/or the second region arranged a corrugated region.

3. The electrical appliance according to claim 2 , wherein an outer diameter of the cable bushing in the second region has a periodic curve in an axial direction.

4. The electrical appliance according to claim 2 , wherein an outer diameter of the cable bushing, measured in a plane having a normal direction aligned parallel to an axial direction, has a periodic curve in the axial direction.

5. The electrical appliance according to claim 2 , wherein the outer diameter of the cable bushing has local maxima as a function of a distance from the housing.

6. The electrical appliance according to claim 5 , wherein the local maxima decrease strictly monotonically and/or have smaller values with increasing distance from the housing.

7. The electrical appliance according to claim 5 , wherein at least one of the local maxima has a greater value than a value of a clear inside diameter and/or largest inside diameter of the recess of the housing.

8. An electrical appliance, comprising:
a housing;
a printed circuit board including an illumination device surrounded by the housing;
a cable bushing projecting through a recess in the housing and formed of a transparent material; and
a cable passing through the cable bushing;
wherein the cable bushing has a first region and a second region, the first region having a cylindrical outer circumference, and the second region being arranged as a corrugated region;
wherein the outer diameter of the cable bushing in the second region decreases with increasing distance from the housing.

9. The electrical appliance according to claim 8 , wherein the illumination device is adapted to emit light and/or a light cone that irradiates into an end face of the cable bushing and/or in an axial direction into the cable bushing.

10. The electrical appliance according to claim 8 , wherein the illumination device is adapted to emit light and/or a light cone that irradiates into the cable bushing in a radial direction with respect to a direction of the cable bushing direction and/or a bore axis.

11. The electrical appliance according to claim 8 , wherein the second region is adjacent to the first region.

12. An electrical appliance, comprising:
a housing;
a printed circuit board including an illumination device surrounded by the housing;
a cable bushing projecting through a recess in the housing and formed of a transparent material; and
a cable passing through the cable bushing;
wherein the illumination device is adapted to emit light and/or a light cone that irradiates into the cable bushing in a radial direction with respect to a direction of the cable bushing direction and/or a bore axis;
wherein the cable bushing has a first region and a second region, the first region having a cylindrical outer circumference, and the second region being arranged as a corrugated region; and
wherein the outer diameter of the cable bushing in the second region decreases with increasing distance from the housing.

13. The electrical appliance according to claim 12 , wherein the illumination device includes an LED.

14. The electrical appliance according to claim 12 , wherein the transparent material is transparent to light emitted by the illumination device.

15. The electrical appliance according to claim 12 , wherein the cable bushing is arranged as a rotational body, an axis of symmetry and/or an axis of rotational symmetry of the rotational body is aligned parallel to an axial direction and/or a direction of the cable bushing.

16. The electrical appliance according to claim 12 , wherein the recess is arranged as a round hole, a center axis and/or a center line of the round hole aligned parallel to an axial direction, or a bore hole and/or a threaded bore, a bore axis of the bore hole and/or the threaded bore aligned parallel to the axial direction.

17. The electrical appliance according to claim 12 , wherein the housing is made of a material that does not allow the light emitted by the illumination device to pass through.

18. The electrical appliance according to claim 12 , wherein the recess is arranged as a round hole.

19. The electrical appliance according to claim 12 , wherein at least one connecting element that includes a metallic contact element is arranged on the printed circuit board, the cable surrounds and/or radially surrounds electrical lines that are routed to a respective connecting element, and electrically connected to a respective metallic contact element, the contact element being solder connected to a conductive path of the printed circuit board.

20. The electrical appliance according to claim 12 , wherein the illumination device is adapted to emit light and/or a light cone that irradiates into the cable bushing in the radial direction into a region of the cable bushing projecting into an inner space of the electrical appliance surrounded by the housing.

21. The electrical appliance according to claim 20 , wherein the region has a cylindrical outer circumference.

22. The electrical appliance according to claim 12 , wherein a material of the cable bushing is a polycarbonate, a PVC, and/or a polyethylene.

23. The electrical appliance according to claim 22 , wherein an adhesive is arranged between the cable bushing and the housing for additional sealing of the cable bushing towards the housing.
