Definitions

  • the invention relates to a hand grenade detonator with a detonating cap, a delay charge, a primary charge and a plastics safety disc that prevents a direct breakthrough of the detonating flame of the detonating cap onto the primary charge when the delay charge is missing.
  • a safety disc is further known from DE 26 48 331 B1 that comprises two portions, namely a plastics foil and an annular supporting or retaining element for said foil, wherein the foil is connected to the supporting element by being flattened down with the housing.
  • the object of the invention is thus to remove this disadvantage, and proposes that the safety disc is formed by means of a one-piece, pot shaped plastics element that includes a supporting ring and a thin layer covering its central free space.
  • the safety disc is composed of a polyamide, but other temperature-resistant plastics can also be used.
  • FIG. 1 a safety disc according to the prior art
  • FIG. 2 a hand grenade detonator in partial longitudinal section
  • FIG. 3 a safety disc according to the invention.
  • a hand grenade detonator 1 is provided with a primary charge 2 , a delay assembly 3 , and a detonating cap 4 that can be struck by a striker that is not shown.
  • a safety disc 5 is inserted between the delay assembly and the primary charge 2 that can be destroyed by the burning delay assembly 3 but not by the detonating flame.
  • FIG. 1 shows a conventional safety disc 5 that is provided with a metallic ring 51 and a tin-plated lead foil 52 , which covers over the annular aperture 61 .
  • the 3 is a one-piece, pot-shaped plastics element 8 in that with the exception of a thin layer 7 , a central free space 6 is formed.
  • the thin plastics layer 7 is sufficient to prevent the breakthrough of the detonating cap flame.
  • the plastics element 8 is composed of a polyamide or another temperature-resistant plastics material.
