  • Patent number: 11537084
    Abstract: A timepiece movement includes a photovoltaic cell which is attached to the upper surface of a support plate, preferably by adhesive bonding. On the other side of the cell, on its lower surface, the support plate is provided with a plurality of nuts. An electrical module including a flat surface is attached to the support plate with the nuts. The module is provided with several openings whose position and dimensions correspond to those of the nuts, so that the nuts pass through the openings, allowing the flat surface of the module to be placed in contact with the support plate. The module is secured to the support plate by screws, screwed into the nuts. The connection via the nuts secures the photovoltaic cell to the electrical module and ensures shock resistance, without requiring a lateral support.
