Definitions

  • Such coil holder therefore serves at the same time as conductor plate for the electronic components.
  • This known design has further considerable disadvantages in terms of production. As thesecomponents are to be soldered to the conductor plate in the course of series or quantity production in a zinc bath, this step or operation must be carried out before the coils are placed in the coil holder. As the coils are often injured when being inserted in the coil holder, the entire unit becomes unserviceable and'useless and must be discarded if the coil wire breaks, when the coil is glued to the coil holder.
  • the invention aims at the avoidance of these disadvantages, which ina timepiece of the above-mentioned disadvantages, is due to the fact that the coil holder and the conductor plate are separate parts and that the conductor plate is detachably fastened to the coil holder, and the coil holder, in turn, is releasably fastened to the oscillatoryframe.
  • the coil is held between two elastic lobes of the coil holder in a tonglike fashion. In such case the use of an adhesive may be avoided.
  • This assembly has the disadvantage that the elastic lobe parts can easily touch and damage the coil wire upon manipulation and insertion of the coil. It is further possible that due to vibrations the coil becomes disengaged and loose in the coil holder.
  • the current supply to the conductor plate occurs through plugs which are connected with the coil holder and the conductor plate by means of rivets.
  • the design may be such that at the same time the casing surrounding the clockwork is fastened to such rivets, without this attachment leading to a defon'nation of the position of the coil holder relative to the conductor plate and vice versa.
  • the invention fulfills also the purpose of avoiding still further disadvantages in that the coil holder of the above-mentioned type possesses walls which embrace a part of the coil and are provided with slots for receiving and distributing the applied adhesive substance. By these slots it is ensured that the introduced adhesive is in a restricted area and cannot flow onto the coil surface as well as onto the surface of the coil holder.
  • a further object of the invention resides in the provision of means rendering the possibility of employing less highly trained personnel and work force and of markedly cutting down the manufacturing cost of vital electronic component parts and their buildup for use in precision and like industries.
  • FIGS. 1 to 8 show two embodiments according to'the inven' tion. 7
  • FIG. 1 illustrates the rear view of a coil holder with installed conductor plate, the balance wheel with frame being shown behind said coil holder.
  • FIG. 2 is a section through FIG. I taken along line 2-.-2 and seen in side elevation.
  • FIG.'3 shows a part of the coil holder of a second embodiment pursuant to the "invention, the attachment of the coil holder being seen in front view. 1
  • FIG. 4 illustrates the holder of FIG. 3 in side view.
  • FIG. 5 is a top plan view of FIG. 4.
  • FIGS. 6 to 8 are corresponding views to those of FIGS. 3 to 5 illustrating coil attachment positions.
  • FIG. 9 is an exploded view, seen in perspective, of the embodiment of FIG. 1.
  • FIGS. 1 and 2 there is disclosed a coil holder 1 with inserted coils 2 and 3.
  • the coil holder 1 is fastened to two posts 7 of the frame 30 by the engagement with two corresponding openings 4 and 5.
  • the coil holder '1 is L-shaped in cross section.
  • One leg of the coil holder supports coils 2 and 3, while the other leg 18 carries conductor plate 6.
  • At the juncture of the two legs of the coil holder 1 is a clearance or opening 8. Into this opening 8 there protrudes the projecting piece or part 9 of the conductor plate 6 carrying the coil connections (contact bank).
  • the conductor plate 6 is retained on the coil holder 1 by means of knob-shaped elements or posts 7.
  • part 9 of this plate 6 may be reduced in length and kept as short as possible without the danger that upon subsequent and gradual tensioning of the plastic holder 1 the coil connection wires would tear or break.
  • part 9 is press fitted onto the coil holder 1 in the direction of coils 2, 3 through pressure exerted onto wall 10 of opening 8.
  • the frame or vibrator frame 30 serves to journal and suspend the balance wheel mechanism, especially the spiral balance wheel spindle 31.
  • the spiral hairspring (not shown), a first oscillatory element 32 and a second or lower oscillatory element 38.
  • Element 32 carries two permanent magnets 39, one of which induces in coil 2, upon oscillation movement of the balance unit, a voltage which is amplified in a transistor circuit (not shown, but known per se)'and furnishes in the working coil 3 a pulsetype current, which. brings about via permanent magnet 39 adjacent coil 3 a mechanical drive pulse acting on the oscillatory timepiece system.
  • the components of the transistor circuitry are arranged and mounted on the conductor plate 6 (see FIG. 9 for the sake of clarity).
  • plugs 11 and 12 for the supply of electric current. These plug plates are fastened by rivets 13, which are riveted on one hand by a rivet head 16 to plugs l1, l2 and are anchored on the other hand, to conductor plate 6 by means of rivet head force fitted on plate 6 (FIG. 2).
  • each rivet 13 is provided with an offset part 17, so that the rivets taper in the direction of plugs 11, 12.
  • the bores in the coil holder 1, 18 are adapted toconform to such rivet shape. In this way it becomes possible that the sides of the rivets 13 facing the plugs 11, 12 carry each a threaded bore 14. By means of these threaded bores 14, the work capsule (not shown) can be attached and held in position.
  • the tightening forces on the capsule are again absorbed exclusively by coil holder 1, 18.
  • the work capsule extends over the entire clockwork and out of its rear walls project the pins of plugs ll, 12 which serve to connect the timepiece to an electric current supply source.
  • the attachment of the coil holder 1 and oscillatory frame is carried out through posts on the oscillation frame, on which the coil holder is engaged by means of bores 4 and 5.
  • a catch-type attachment as shown in FIGS. 3 to 5.
  • This snap attachment as shown in these figures can be utilized also as attachment means carried out between coil holder 1 and conductor plate 6, the posts 24.
  • coil holder 1 there is inserted a section of coil 2 or 3 as the case may be.
  • the detachable connection with the oscillatory frame occurs via these pins 23 and 24, which are each provided with a central slot 25, 26.
  • These yieldable pins 23, 24 are inserted in corresponding bores of frame 30 where they snap in and remain in engagement.
  • On the coil holder side located opposite these pins there is arranged a set pin 29 which rests on a bearing surface of frame 30 and together with pins 23.and 24 ensure the proper and accurate position of the coil 2 and coil holder 1.
  • the wire ends of the coil are introduced into slot 28 ofpin 27 and are wound for position on and around this pin.
  • the coil holder 1 can also be connected to the conductor plate 6 in approximately the same manner.
  • the coil holder 1 has a recess 36 (FIG. 7) for accommodating coil 2. Thereby coil 2 is embraced along a section thereof in a tong-shaped manner.
  • the top side of the coil holder has a slot 33, which terminates in and communicates with a slot 34 on the rear wall provided with recess 36.
  • This slot or recess 36 ends at the underside and is in the form of a groove 35 as seen on the bottom. It is advantageous if, these two slit systems are arranged side by side on the holder 1, so that part 37 extending between the two slots 33 assumes a design which. is yieldable at the top of the holder. Slight elasticity would suffice,'as a retaining or clamping effect is only required during the time that the adhesive is not yet set and hardened.
  • 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.
  • a further pin is arranged having a slot for anchorage on said framel 4.
  • said coil holder carries at least one fitting pin, which comes to rest on a bearing face provided on said frame.
  • said coil holder carries a pin with an axial slot arranged for anchoring therein conductor ends of said coil.
  • 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 atthe juncture of said two legs.
  • the walls defining said coil holder are structured to embrace a part of said coil and are provided with slots for receiving an adhesive substance to attach said coil in the coil holder.
  • 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.
  • said coil holder isprovided 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.
