Definitions

  • moving-coil systems which include a single tensioned wire or a single tensioned ribbon.
  • the mirror is cemented to this ribbon.
  • the moving coil arrangement is also fastened to the ribbon. So that the moving-coil arrangement is symmetrical with respect to the axis of rotation, the known moving-coil systems contain two moving coils which are cemented symmetrically to the tensioned wire or the tensioned ribbon.
  • the configuration of the moving-coil arrangement with two rotating coils is relatively expensive because two individual coils must be wound for one moving-coil system and must then further be connected together electrically.
  • the moving-coil system of the invention is suitable for use in such devices as a light-beam galvanometer, light-beam oscillograph and the like.
  • the moving-coil system of the invention includes as a feature a suspending element upon which a single rotating coil defining a window is mounted. The rotating coil is securely mounted on the suspending element in a position inclined with respect thereto so as to cause the suspending element to extend through the window.
  • the suspension element can be, for example, a single tension wire or a single tension ribbon. If required, the suspension element can be a composite tensioning de vice composed of several parts with different crosssections.
  • a single moving coil is therefore sufficient and this has a favorable effect on the manufacturing costs.
  • This rotating coil is advantageously connected to the ten sioned wire or the tensioned ribbon by gluing.
  • the drawing is a schematic diagram of a movable coil assembly according to the invention.
  • the moving-coil system includes a suspension element in the form of tension wire 1 on which a mirror 2 is fastened, for example, by means of gluing.
  • the tensioned wire 1 serves at the same time for feeding in the current and is electrically connected at a point 3 with one end 4 ofa moving coil 5 by soldering; the other end 6 of the moving coil is brought out free.
  • the moving coil 5 is fastened at the tensioned wire 1 at an angle, for instance, by gluing, and, in particular, in such a manner that the tensioned wire 1 passes through the coil window 7.
  • the moving coil is thus connected with the tensioned wire 1 at mutually adjacent end-faces 8 and 9.
  • the connection can be made by gluing cement.
  • the invention provides a moving-coil system which can be manufactured very inexpensively by using a tensioned wire or a tensioned ribbon as the carrier for the mirror and the single rotating coil.
  • a moving coil system for a light-beam galvanorneter, light-beam oscillograph and the like comprising a suspending element defining a longitudinal axis; a mirror securely attached to said suspending element; and, a single undivided rotating coil defining a window, said rotating coil being securely mounted on said suspending element in a position inclined with respect thereto so as to cause said suspending element to extend through said window to conjointly define an acute angle therewith and to cause the composite of said suspending element and said rotating coil to be balanced with respect to said longitudinal axis.
