  • ABSTRACT [22] Filed: Nov. 1, 1971 An electric clock mounting and contact apparatus in- A l No v 194 726 cluding an electric clock housing, an electric drive circuit positioned within the housing, pillar means extending between the housing and the electric drive cir- Foreign Application Priority Data cuit for supporting said electric drive circuit, the pillar Nov. 6 1970 Germany ..P 20 54 757.3 means being electrically conductive and elecmcal contact with the electric drive circuit, an electrical [52] [1.8. CI. ..58/23 R, 58/52 Contact means connected exteriorly of the electrical 51 lm. CI.
  • the known embodiments require considerable expenditure for bringing out the plug contacts, for their attachment and for the additional attachment of the plate made of insulating material receiving the electricaldriving circuits, as well as of the case of the clock mechanism.
  • At least one object of the present invention is the production of an electric clock of the initially mentioned'type where the current supply connection for the electric driving circuit is accomplished in a particularly simple manner with little expenditure.
  • the pillars feeding in the current which are connected with the plug contacts, can be developed preferably as attaching elements of a carrying part for the mechanism case and for the plug contacts, said part containing the driving circuit.
  • the carrying element for the electrical driving circuit can be a plate made of insulating material, connected with printed circuits and also receiving the electronic construction elements.
  • the plug contacts may be provided with projections or recesses which are engaged with suitable recesses or projections of the mechanism case of of a part connected with said case, whereby at least one of these recesses or one of these projections is insulated with regard to the case of the mechanism.
  • FIG. 1 is a bottom plan view of an electric clock mechanism according to the invention and particularly discloses a pair of spaced electrical contact plugs suitable for connection with an exterior voltage source;
  • FIG. 2 is a sectional view taken along section line lllI of FIG. 1 and particularly discloses the connection of pillars between an electric clock housing and an electric drive circuit positioned within the interior of the housing;
  • FIG. 3 is a bottom plan view partially broken away to disclose a plate receiving an electrical drive circuit
  • FIG. 4 discloses a sectional view taken along section line lV-IV in FIG. 1;
  • FIG. 5 discloses a sectional view taken along section line V-V in FIG. 1.
  • the reference number 10 indicates a clock mechanism, which is held together by means ofpillars 12, 13 and 14 of the frame and with the help of nuts 15, 16 and 17, and is attached to a base plate 11.
  • Nuts 15 and 17 serve at the same time as spacers, on which a plate 18 made of insulating material and carrying the printed circuits and electrical switching elements 20 for the driving circuit has been attached with the help of pillars 21 and 22.
  • This conductor plate also carries for example a coil 19. Pillars 21 and 22 have thread lugs 21a and 22a, which are screwed into the distancing nuts 15 and 17.
  • Distancing nut 15 consists of electrically non-conductive material.
  • the printed circuits for example 29 and 30 in FIG. 3, are arranged for practical purposes on the right side of plate 18 in FIG. 2, and printed circuits 29 and 30 (FIG. 3) have been provided running around the attaching holes in plate 18 and, of course, in such a way that shoulders 21c and 22c provided on pillars 21 and 22 will fit against these printed circuits 29 and 30, and thus establish an electric contact.
  • Pillars 21 and 22 furthermore are provided with thread lugs 21b and 22b, on which attaching nuts 23 and 24 can be screwed on. These nuts 23 and 24 serve for attachment of the clock housing 27 and at the same time for attachment of the contact plugs 25 and 26, of
  • plug 26 fits directly, that is to say electrically conductively against housing 27, while between housing 27 and plug 25 a part 28 made ofinsulating material has been inserted, which, for practical purposes, also will engage with the appropriate perforation of housing 27 example can be pressed out of case 27, as can be seen in FIG. 5.
  • Plug 26 has been provided with an appropriate recess 26a, which receives projection 27a.
  • a suitable arrangement also has been provided in the case of plug 25, which likewise has been provided with a recess 25a, which receives a projection 28a of part 28 made of insulating material. In this manner both plugs 25 and 26 are secured on case 27 to prevent twisting.
  • case 27 in order to prevent twisting of part 28, made of insulating material, in case 27, said part has been provided with an additional projection 28b which engages with a perforation of case 27.
  • the development according to the invention makes it possible to attach the mechanism case and at the same time and simultaneously to use the attaching elements for the case as a current supply for the electrical driving circuit, whereby these attaching elements additionally will hold the current supply plugs.
  • the clock according to the invention therefore can be produced with a particularly small cost.
  • a plate composed of insulating material operable to support printed circuits in electrical'contact with a said pillar means and to support electronic drive circuit elements.
  • At least one of said pair of pillars being electrically insulated from said electric clock housing.
  • plug contacts one electrically connected to each of said electrically conductive pillars, said plugs having recesses suitable for non-rotatable engagement with projections extending from said electric clock housing, and at least one of said plug contacts being electrically insulated from said electric clock housing.
