摘要:
A flexible printed circuit, located within a digital watch, which provides the interconnection circuitry between the digital watch's electro-optical displays and the electronic components and the batteries and the watch push buttons. The flexible printed circuit consists of a pliable plastic material to which battery contacts, push button contacts, interconnection circuitry (between the batteries, watch push buttons, electronic component, and electro-optical displays), and contacts for the electronic components and displays are affixed.
摘要:
Digital display is retained in upper spacer of watch module by means of screws and a spring having resiliently deflected fingers engaging the upper spacer. Resilient deflection at both the screw attached end and the spring finger end resiliently restrains the display and ensures contact of the display with an elastomeric type connector.
摘要:
Electronic substrate of the electronic watch is the principal carrier of the electronics and electrical interconnections. It carries two alignment notches with top and bottom spacers embracing the substrate and engaging the alignment notches. The visual horological display is located in the top spacer and the batteries are located in the bottom spacer. Springs press onto the substrate and are contactable for input to the watch electronics. All important parts are keyed together for ease of assembly and accuracy of alignment.
摘要:
A digital watch having an elastomer spacer block which houses the watch batteries, the oscillator crystal, and the substrate with its electronics and optical display elements mounted thereon; all in the same cavity. Said digital watch also has a flexible printed circuit which contacts the batteries and electrically connects them to the watch electronics. The flexible printed circuit is also used to turn on and to set the time by grounding the contact on the printed circuit to the case.

Electronic substrate of the electronic watch is the principal carrier of the electronics and electrical interconnections. Top and bottom spacers embrace the substrate. Contact springs press onto and clamp on the substrate and contact the circuitry on the substrate. The springs are contactable for input to the watch electronics.
