发明名称 RETAINING DEVICE FOR A CELL IN AN ELECTRONIC WRIST-WATCH
摘要 A battery is placed in a recess in the plate of an electronic wrist watch movement. The battery cover presses against a spring contact fixed to a plate bearing a printed circuit. An insulating sheet insulates the battery from an inner flange of the movement plate. Disposed on the bottom of the battery casing is a pressure bracket having arms which resiliently grip the sidewall of the casing. Resilient radial tongues of the bracket are bent so as to be in contact with the back of the watch case which presses against the assembly at the time of casing-up so as to hold the battery in place. The connection to ground is established by a contact part and a screw, as well as by the contact between the battery casing and the movement plate and via the back of the watch case.
