Abstract
Abstract A new and improved shock-resistant electronic watch module is provided, which comprises a case, a frame of electrically insulating material mounted in the case, a lens plate of an electrically insulating material being flexibly mounted on a first side of the frame, a substrate mounted to the lens plate, a frequency standard, a frequency divider, an electro-optical display means, and means for driving the display, all being mounted to the substrate, and, a battery removably mounted on a second side of the frame and being electrically coupled to the substrate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
165 words
An electronic wristwatch comprising: a case; a cup-shaped module frame of electrically insulating material having a plurality of retainers with tab receiving openings located on the periphery thereof; a lens plate of an electrically insulating material including a corresponding plurality of flexible tabs disposed on the periphery thereof for engaging corresponding ones of said retainers on said frame, thereby flexibly suspending said lens plate in said frame; a substrate mounted to said lens plate and having rigidly mounted thereto a frequency standard, a frequency divider, an electro-optical display means, and means for driving said display, said substrate including printed electrical circuit means for coupling the constituent components of the circuit forming said electronic watch; at least one battery mounted in an opening in said frame and having a terminal thereof electrically coupled to the printed means on said substrate; and means for securing said at least one battery in said frame and for coupling a second terminal of said battery to circuitry on said substrate.
Claim 2
Dependent Claim
165 words
An electronic wristwatch comprising: a case; a cup-shaped module frame of electrically insulating material having a plurality of retainers with tab receiving openings located on the periphery thereof; a lens plate of an electrically insulating material including a corresponding plurality of flexible tabs disposed on the periphery thereof for engaging corresponding ones of said retainers on said frame, thereby flexibly suspending said lens plate in said frame; a substrate mounted to said lens plate and having rigidly mounted thereto a frequency standard, a frequency divider, an electro-optical display means, and means for driving said display, said substrate including printed electrical circuit means for coupling the constituent components of the circuit forming said electronic watch; at least one battery mounted in an opening in said frame and having a terminal thereof electrically coupled to the printed means on said substrate; and means for securing said at least one battery in said frame and for coupling a second terminal of said battery to circuitry on said substrate.
Claim 3
Dependent Claim
31 words
An electronic wristwatch as in claim 1 including switch contact means disposed in said case for operating said electro-optical display means to enable display of the contents of said frequency divider.
Claim 4
Dependent Claim
73 words
An electronic wristwatch as in claim 2 further characterized by said substrate including normally open contacts in substantial alignment with said switch means, said case and said means for securing both being formed of electrically conductive material and in contact with one another, and said switch means being in contact with said case such that operation of said switch contact means couples the second terminal of said battery to said normally open contacts.
Claim 5
Dependent Claim
26 words
An electronic wristwatch as in claim 3 further characterized by said normally open contacts being independent from the suspension of said lens plate in said frame.
Claim 6
Dependent Claim
58 words
An electronic wristwatch as in claim 1 further characterized by said frame including a pair of tab receiving means on the bottom side thereof, and said means for securing including a pair of tabs formed thereon such that said means for securing is urged against the bottom side of said frame to secure the battery in said frame.
Claim 7
Dependent Claim
54 words
An electronic wristwatch as in claim 5 including at least two batteries both secured in said frame by said means for securing and including an electrical contact means located in an opening in said frame such that an electrical connection is formed between said means for securing and the circuit traces on said substrate.
Claim 8
Dependent Claim
18 words
An electronic wristwatch as in claim 5 wherein said means for securing comprises a resilient electrically conductive material.
Claim 9
Dependent Claim
145 words
For use in an electronic wristwatch having a case and a watch module therein, said module including a frequency source, frequency divider and logic means, display means, driver means for said display means, and battery means; a shock-resistant support for retaining said watch module within said case comprising: a cup-shaped frame of electrically insulating material having a peripherial lip and a plurality of retainer clips with tab receiving openings located in the peripherial lip of said frame, and having at least one opening therein for receiving a battery; and a lens plate assembly including a lens plate and a substrate supporting the electronic components of the wristwatch, said lens plate having a plurality of flexible tabs disposed on the periphery thereof for engaging corresponding ones of said retainer clips in said frame such that said lens plate assembly is flexibly suspended in said cup-shaped frame.
Claim 10
Dependent Claim
145 words
For use in an electronic wristwatch having a case and a watch module therein, said module including a frequency source, frequency divider and logic means, display means, driver means for said display means, and battery means; a shock-resistant support for retaining said watch module within said case comprising: a cup-shaped frame of electrically insulating material having a peripherial lip and a plurality of retainer clips with tab receiving openings located in the peripherial lip of said frame, and having at least one opening therein for receiving a battery; and a lens plate assembly including a lens plate and a substrate supporting the electronic components of the wristwatch, said lens plate having a plurality of flexible tabs disposed on the periphery thereof for engaging corresponding ones of said retainer clips in said frame such that said lens plate assembly is flexibly suspended in said cup-shaped frame.
Claim 11
Dependent Claim
35 words
A shock-resistant support as defined by claim 8 wherein said cup-shaped frame receives battery means from one side of said case and receives said lens plate for display through the other side of said case.
