Definitions

  • the invention relates to a plastic shell for an electronic wristwatch.
  • the bottom of the housing is provided with a conical opening, which is used to replace the battery and which accommodates an armored insert element for tight sealing.
  • the invention has for its object to achieve a tight closure of the conical housing opening 15.
  • the tight closure demands from the elastic, flexible plastic closure piece 1 that the dimensional accuracy of the press fit 13 is ensured.
  • the conical closure outer surface 7 must guarantee dimensional stability in the event of temperature changes.
  • the dimensional stability of the conical closure outer surface 7 is achieved with a chrome steel ring 4.
  • the chrome steel ring outer surface 5 counteracts with its support function the heat deformation, so that the press fit 13 is not endangered.
  • the truncated cone 3 serves to receive and axially secure the chrome steel ring 4.
  • FIG. 2 shows a section through the closure piece without reinforcement
  • FIG. 3 shows a section through the reinforced closure piece
  • Fig. 4 shows a section through the armored closure piece in the plastic housing body.
  • the chrome steel ring shown in Fig. 1 is light

Abstract

Une coque en plastique est pourvue, dans son fond (14), d'une ouverture conique (15) pour le remplacement de la pile. Pour fermer cette ouverture (15), on utilise un élément de fermeture armé (1) en matière plastique souple, élastique, qui présente en son centre un cône tronqué (3) moulé axialement. Le cône tronqué (3) sert à loger et à retenir dans le sens axial une bague d'acier chromé (4) qui assure la stabilité dimensionnnelle de l'élément de fermeture armé (1) dans la zone de pression (13).
