Abstract

A structure for a timepiece includes a middle part and a back cover that confines an electronic or electrical module. The module includes a plate, at least one circuit with at least one electrical contact area, and a connecting contactor. The plate includes a compartment that is arranged to receive an electrical energy accumulator. The connecting contactor provides an electrical connection between the accumulator and the at least one contact area. The contactor is rigid and includes an elastic return that tends to return the contactor to a rest geometry. The contactor includes at least a first arm and at least a second arm that together form a clamp that presses the circuit and the accumulator towards each other.
