Abstract

Battery operated appliances are provided. Some appliances include a housing defining a chamber having an interior wall, electronics within the chamber, a battery cover, and a closing system including (a) a first electrically conductive member secured to the battery cover, and (b) a second electrically conductive member secured to the interior wall of the housing and configured to engage the first electrically conductive member and thereby mechanically secure the battery cover to the housing while also establishing electrical contact between the first and second electrically conductive members.

Claims (38)

1. A battery operated appliance comprising a housing defining a chamber having an interior wall, electronics within the chamber, a 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 interior wall of the housing and configured to engage the first electrically conductive member and thereby mechanically secure the battery cover to the housing while also establishing electrical contact between the first and second electrically conductive members.
2. The appliance of claim 1, wherein the first and second electrically conductive members are configured to engage each other by rotation of the battery cover relative to the housing.
3. The appliance of claim 2, wherein the second electrically conductive member includes a circumferentially extending slot having an open end and the first electrically conductive member includes a hook configured to slide into the slot through the open end during rotation.
4. The appliance of claim 1, 2 or 3, wherein the interior wall of the housing is generally cylindrical.
5. The appliance of claim 1, wherein outer surfaces of the housing and battery cover are generally cylindrical.
6. The appliance of claim 1, wherein the first electrically conductive member includes 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.
7. The appliance of claim 6, wherein the first electrically conductive member includes two or more spring elements.
8. The appliance of claim 7, wherein each spring element provides an electrical contact between the first and second electrically conductive members.
9. The appliance of claim 1, wherein the first and second electrically conductive members are secured to the battery cover and housing, respectively, by a snap fit.
10. The appliance of claim 1, wherein the second electrically conductive member includes a portion configured to make electrical contact with an electronic sub-assembly of the appliance.
