Abstract

Abstract Electronic watch module is constructed of a spacer block, a substrate on the spacer block carrying electronic components thereon, and a cover over some of the electronic components. Basic rate control of the electronic watches is provided by a crystal which is mounted in a can. An opening in the spacer block receives the crystal can, and deflectable fingers on the spacer block restrain the crystal can in place.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 164 words
A spacer block for an electronic watch module, said spacer block being formed of resilient synthetic polymer composition material and having a top surface and a bottom surface and having a battery opening extending into said block from one of said surfaces for receipt of a battery for powering the electronic watch module, said spacer block having a crystal can opening therein from one of said surfaces for positioning in said opening an electronic crystal in a crystal can, said block having resilient ears mounted on one of said surfaces said resilient ears being monolithically formed with the remainder of said spacer block and permanently attached thereto and extending adjacent said crystal can opening so that said resilient ears can be resiliently bent away from said opening for introduction of a crystal can into said crystal can opening and said resilient ears being resiliently positionable over the crystal can in said crystal can opening to retain said crystal can in said crystal can opening.
Claim 2
Dependent Claim 164 words
A spacer block for an electronic watch module, said spacer block being formed of resilient synthetic polymer composition material and having a top surface and a bottom surface and having a battery opening extending into said block from one of said surfaces for receipt of a battery for powering the electronic watch module, said spacer block having a crystal can opening therein from one of said surfaces for positioning in said opening an electronic crystal in a crystal can, said block having resilient ears mounted on one of said surfaces said resilient ears being monolithically formed with the remainder of said spacer block and permanently attached thereto and extending adjacent said crystal can opening so that said resilient ears can be resiliently bent away from said opening for introduction of a crystal can into said crystal can opening and said resilient ears being resiliently positionable over the crystal can in said crystal can opening to retain said crystal can in said crystal can opening.
Claim 3
Dependent Claim 76 words
The spacer block for electronic watch module of claim 1 wherein ear supports are formed on said surface of said spacer block to extend away from said surface of said spacer block and said resilient ears are mounted on said ear supports, said resilient ears each having an engagement surface facing said surface of said spacer block, so that a flange on the crystal can can be engaged by said engagement surface on said resilient ears.
