Solid-state electronic watch assembly

Claim 1

In a solid state electronic watch provided with a generally rectangular case having a window formed on one end thereof, and an assembly receivable within said case, said assembly comprising: A. an insulating block having a ledge projecting from the forward section thereof adjacent said one end of the case, said block having cavities therein to accommodate discrete elements, including a cavity in the rear section of the block to receive a battery cell, B. an electro-optic display module formed by a chip constituted by a group of digital display stations mounted on a rectangular board on whose fact at either edge thereof is an array of terminals for applying drive signals to the stations; C. an integrated electronic circuit module formed by an integrated circuit chip mounted on a like board on whose face at either edge thereof is an array of corresponding terminals, said integrated electronic circuit being constituted by a high-frequency standard whose output is applied to a divider to produce low-frequency timing pulses and a display actuator responsive to said pulses, said frequency standard being constituted by an oscillator operating in conjunction with a quartz crystal unit, which is one of the discrete elements received in one of said cavities, said electronic circuit, when energized, functioning to generate said drive signals, said modules being mounted in back-to-back relation on said ledge, with the display stations exposed to view through the window of said case, and D. a flexible printed circuit board overlying said block for electrically interlinking interlinking the terminals of the modules and connecting the integrated electronic circuit to discrete elements held in the cavities of the block, said flexible board including a pair of extensions having an array of conductive lines, and means connected to some of said lines to engage and interconnect the edge terminals of said modules, said means being constituted by a pair of multi-connector clamps, each clamp being formed by a pair of flexible tines which are adapted to engage and electrically shunt a pair of corresponding edge terminals of said modules.
