Battery-operated razor

1. A battery operated razor comprising:

a generally cylindrical housing defining a chamber,

a generally cylindrical battery cover, the battery cover and/or the housing being configured to contain one or more batteries, and

a closing system, including a first electrically conductive member secured to the battery cover, and a second electrically conductive member secured to the housing and configured to engage the first electrically conductive member by rotation of the battery cover relative to the housing, thereby mechanically securing the battery cover to the housing while also establishing electrical contact between the first and second electrically conductive members,

wherein the second electrically conductive member includes a portion configured to make electrical contact with an electronic sub-assembly within the chamber, the portion comprising one or more arms having a terminal hook wherein the hook engages a corresponding structure on the sub-assembly.

2. The razor of claim 1 wherein the one or more arms mechanically secure the sub-assembly in place and provide electrical connection between the one or more arms and the sub-assembly.

3. The razor of claim 1 wherein the hook is snap-fit into a groove or recess of the sub-assembly.

4. The razor of claim 1 wherein the hook is press-fit into a groove or recess of the sub-assembly.

5. The razor of claim 1 wherein at least one of the first and second electrically conductive members comprises a spring element configured to apply an axial force between the housing and battery cover when the first and second electrically conductive members are engaged.

6. The razor of claim 5 wherein the spring element provides an electrical contact between the first and second electrically conductive members.

7. The razor of claim 1 wherein the first and second electrically conductive members are secured to the battery cover and the housing, respectively, by a snap fit.

8. The razor of claim 1 wherein the first electrically conductive element includes an undercut configured to engage a corresponding undercut on an interior wall of the battery cover.

9. The razor of claim 1 wherein the second electrically conductive element includes an undercut configured to engage a corresponding undercut on an interior wall of the housing.

10. The razor of claim 1 wherein the subassembly is configured to drive a vibrating function of the razor.

11. The razor of claim 1 wherein the second electrically conductive member is secured to an interior wall of the housing.

12. A battery operated razor comprising:

a generally cylindrical housing defining a chamber,

a generally cylindrical battery cover, the battery cover and/or the housing being configured to contain one or more batteries, and

a closing system, including a first electrically conductive member secured to the battery cover, and a second electrically conductive member secured to the housing;

wherein the second electrically conductive member includes a portion configured to make electrical contact with an electronic sub-assembly within the chamber, the portion comprising one or more arms having a terminal hook wherein the hook engages a corresponding structure on the sub-assembly.

13. The razor of claim 12 wherein the one or more arms mechanically secure the sub-assembly in place and provide electrical connection between the one or more arms and the sub-assembly.

14. The razor of claim 12 wherein the hook is snap-fit into a groove or recess of the sub-assembly.

15. The razor of claim 12 wherein the hook is press-fit into a groove or recess of the sub-assembly.

16. The razor of claim 12 wherein the second electrically conductive element comprises one or more undercuts configured to engage one or more corresponding undercuts on an interior wall of the housing.
