Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 157 words
A battery assembly for electronic timepieces comprising: a battery having a positive terminal with a cylindrical surface and a negative terminal with a top surface disposed in a plane perpendicular to the axis of the positive terminal; (b) means for simultaneously positioning said assembly and for providing electrical connection to said battery, comprising: (1) a supporting frame having a central bore through which the battery is inserted in such a manner to be securely fitted to the frame; (2) a lead plate having an end securely fitted and electrically connected to the negative terminal of the battery; and (3) an insulating member supported by the frame and disposed to cover the negative terminal and the lead plate; (4) the supporting frame being provided with an engaging portion which is engaged with a stop of a substrate of the timepiece for preventing a dial plate of the timepiece from being depressed by the battery through the insulating member.
Claim 2
Dependent Claim 157 words
A battery assembly for electronic timepieces comprising: a battery having a positive terminal with a cylindrical surface and a negative terminal with a top surface disposed in a plane perpendicular to the axis of the positive terminal; (b) means for simultaneously positioning said assembly and for providing electrical connection to said battery, comprising: (1) a supporting frame having a central bore through which the battery is inserted in such a manner to be securely fitted to the frame; (2) a lead plate having an end securely fitted and electrically connected to the negative terminal of the battery; and (3) an insulating member supported by the frame and disposed to cover the negative terminal and the lead plate; (4) the supporting frame being provided with an engaging portion which is engaged with a stop of a substrate of the timepiece for preventing a dial plate of the timepiece from being depressed by the battery through the insulating member.
Claim 3
Dependent Claim 39 words
The battery assembly as defined in claim 1 wherein the engaging portion has a first surface disposed in parallel with the surface of the positive terminal and a second surface disposed in a plane perpendicular to the first surface.
Claim 4
Dependent Claim 31 words
The battery assembly as defined in claim 1 wherein said lead plate has a free end, and an insulating sheet is attached to the free end portion of the lead plate.
Claim 5
Dependent Claim 24 words
The battery assembly as defined in claim 1 wherein the insulating member includes a cut-out portion, the lead plate extending through said cut-out portion.
Claim 6
Dependent Claim 25 words
The battery assembly as defined in claim 1 wherein a marginal portion of the insulating member is disposed between the battery and the supporting frame.
Claim 7
Dependent Claim 21 words
The battery assembly as defined in claim 1 wherein the substrate of the timepiece includes a through-hole for accommodating said assembly.
Claim 8
Dependent Claim 26 words
The battery assembly as defined in claim 6 wherein said through-hole is dimensioned for receiving at least the entire cylindrical surface of said battery positive terminal.
Claim 9
Dependent Claim 142 words
A battery assembly for electronic timepieces comprising: (a) a battery having a positive terminal with a cylindrical surface and a negative terminal with a top surface disposed in a plane perpendicular to the axis of the positive terminal; (b) a supporting frame having a central bore through which the battery is inserted in such manner as to be securely fitted to the frame; (c) a lead plate having an end connected to the negative terminal; (d) a contact member extending through a cut-out portion of the supporting frame and contacting the positive terminal of the battery; (e) the supporting frame being provided with an engaging portion which has a first surface disposed in parallel with the surface of the positive terminal and a second surface disposed in a plane perpendicular to the first surface and engaging with a stop of a substrate.
Claim 10
Dependent Claim 142 words
A battery assembly for electronic timepieces comprising: (a) a battery having a positive terminal with a cylindrical surface and a negative terminal with a top surface disposed in a plane perpendicular to the axis of the positive terminal; (b) a supporting frame having a central bore through which the battery is inserted in such manner as to be securely fitted to the frame; (c) a lead plate having an end connected to the negative terminal; (d) a contact member extending through a cut-out portion of the supporting frame and contacting the positive terminal of the battery; (e) the supporting frame being provided with an engaging portion which has a first surface disposed in parallel with the surface of the positive terminal and a second surface disposed in a plane perpendicular to the first surface and engaging with a stop of a substrate.
