  • Battery operated razor
    Patent number: 10414059
    Abstract: Handle is provided for battery operated razors. In some implementations, the handle includes a simple, efficient mechanism for both securing a battery cover to the handle of a razor and at the same time providing a high reliability electrical contact between the battery and electronics of the razor. The mechanism includes a closing system, including a first conductive component slidably attached within the battery cover and biased toward a predetermined axial position, and a second conductive component secured to the interior wall of the grip portion. The first conductive component is configured to interact with the second conductive component and move axially within the battery cover during engagement of the battery cover with the grip portion.
    Type: Grant
