Abstract
Abstract The invention relates to an electronic clock with a balance oscillatory system which is mounted in an oscillating frame and which carries at least one permanent magnet. This permanent magnet moves over at least one fixed coil carried by a coil holder which is detachably connected with the aforesaid frame, a conductor plate being further provided for carrying electric components of an electronic circuitry.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
101 words
In an electronic timepiece structure equipped with an oscillatory balance wheel system, which is mounted on a frame carrying permanent magnet means adapted to move past at least one fixed coil in a coil holder which, in turn, is detachably connected to said frame, and which employs a conductor plate for mounting thereon electronic components of an electronic circuitry; the improvement which is characterized in that said coil holder and said conductor plate constitute separate units, of which the conductor plate is detachably fastened to the coil holder, whereas said coil holder, in turn, is releasably fastened to the said frame.
Claim 2
Dependent Claim
101 words
In an electronic timepiece structure equipped with an oscillatory balance wheel system, which is mounted on a frame carrying permanent magnet means adapted to move past at least one fixed coil in a coil holder which, in turn, is detachably connected to said frame, and which employs a conductor plate for mounting thereon electronic components of an electronic circuitry; the improvement which is characterized in that said coil holder and said conductor plate constitute separate units, of which the conductor plate is detachably fastened to the coil holder, whereas said coil holder, in turn, is releasably fastened to the said frame.
Claim 3
Dependent Claim
39 words
In an electronic structure according to claim 1, characterized in that said coil holder is provided with at least one projecting pin terminating in an axial slot which is shaped for snap engagement with a bore of said frame.
Claim 4
Dependent Claim
23 words
In a structure according to claim 2, characterized in that a further pin is arranged having a slot for anchorage on said frame.
Claim 5
Dependent Claim
31 words
In a structure according to claim 1, characterized in that said coil holder carries at least one fitting pin, which comes to rest on a bearing face provided on said frame.
Claim 6
Dependent Claim
29 words
In a structure according to claim 1, characterized in that said coil holder carries a pin with an axial slot arranged for anchoring therein conductor ends of said coil.
Claim 7
Dependent Claim
66 words
In a structure accordinG to claim 1, characterized in that said conductor plate is fastened to a wall facing said coil holder, said wall having an opening with which a part of said conductor plate is engageable, which part carries coil connections, the front end of said part being force fitted in an opening in a wall directed perpendicular to the plane of said conductor plate.
Claim 8
Dependent Claim
43 words
In a structure according to claim 6, characterized in that said coil holder is L-shaped in cross section, one leg thereof carrying said coils, the other leg thereof mounting said conductor plate, said opening being provided at the juncture of said two legs.
Claim 9
Dependent Claim
28 words
In a structure according to claim 6, characterized in that said conductor plate is connected to said coil holder by means of posts provided on the coil holder.
Claim 10
Dependent Claim
22 words
In a structure according to claim 6, characterized in that said coil holder mounts plug means for the supply of electric current.
Claim 11
Dependent Claim
42 words
In a structure according to claim 9, characterized in that said coil holder carries hollow rivets for retaining said plug means by virtue of each rivet head, whereas said conductor plate is force fitted onto projection means forming parts of said rivets.
Claim 12
Dependent Claim
31 words
In a structure according to claim 10, characterized in that said rivet of said coil holder is provided with an offset part and tapers in the direction of said plug means.
Claim 13
Dependent Claim

Claim 15
Dependent Claim
52 words
In a structure according to claim 13, characterized in that a slot is arranged on one face of said holder which terminates in a recess for said coil, which, in turn, opens into a slot disposed at an opposite face of said holder, said latter slot being groove-shaped to provide a bottom.
Claim 16
Dependent Claim
47 words
In a structure according to claim 13, characterized in that said coil holder is provided with two types of slots, one of which is provided at the top surface of the coil holder which communicates with another slot at the bottom face, which includes a recessed groove.
Claim 17
Dependent Claim
25 words
In a structure according to claim 15, characterized by an intermediate yieldable wall part located between two slots on the top surface of said holder.
