Definitions

  • the invention relates to radio receiving apparatus in which the casing is substantially constituted by a, moulded part, as for example, Bakelite.
  • the object of the invention is to provide a novel method of mounting the components of such an apparatus, which method is cheap and particularly suitable for mass-production.
  • the invention consists in that with a receiving apparatus comprising a casing which is substantially constituted by a moulded part, the inner surface of this part is provided with projections to which the majority of the components of the apparatus are secured.
  • the projections are moulded together with the moulded part in a single operation. They may be provided at any point desired so that the spatial distribution of the components over the interior space of the apparatus may be chosen as favorable as possible and the components are easy of access; care should of course be taken to ensure an easy removal of the aggregate from the moud.
  • the space available within the casing can be utilized more efficiently.
  • the inconvenience of a greater complication of the casing is of no importance for mass-production; the mounting of the components is greatly facilitated so that the apparatus according to the invention can be manufactured, as has been found in a considerably cheaper manner than apparatus equipped with a frame.
  • FIG. i shows an elevation in perspective in which for the sake of clearness most components are omitted.
  • Figs. 2-5 show the manner of mounting the separate components.
  • Fig. 1 shows the moulded part Which substantially constitutes the casing.
  • the rear-side of the casing is entirely open and may be closed after the mounting of the components.
  • the bottom of the casing consists of a piece of material 2, for example of wood, which may be secured to the moulded part by means of screws or the like, said bottom being shown in the figure separated from the moulded part.
  • the bottom may also be made integral with the remainder of the casing, if desired, but a removable bottom affords the advantage that the interior of the casing is more easily accessible and that consequently the mounting of the components is facilitated.
  • the moulded part has a portion 3 which projects within the casing and which has an opening 4 destined for the mounting of a loudspeaker.
  • the aperture 5 serves to provide a scale which is not shown in the drawing.
  • the moulded part has a plurality of projections which are formed so as to render possible an extremely easy mounting of the components.
  • the projections 3 may serve for the mounting of a, transformer, e. g. the output transformer. Subsequent to the moulding of the casing they are provided to that end with a screw thread. Another possibility consists in pressing-in threaded metallic parts.
  • Fig. 2 shows the mounting of a transformer I.
  • projections 8 are intended for the mounting of valve sockets. As is shown in Fig. 4 in plan view, they have an annular shape and are provided with two raised parts which extend diametrically within the ring.
  • the socket may be attached in a bore 10 by means of a screw.
  • annular projections ll into which fit the coils which generally have a cylindrical shape. Owing to their slight weight, they may simply be clamped in the projections and/or be attached to the casing with the aid of cement, screws being not necessary.
  • the parts 52 may serve, for example, to mount part of the scale or indicator device, for example, the guide of the pointer.
  • a support which carries, for example, the tuning condensers and the wave-length switch.
  • the cylindrical supports are slid between the projections i l and i5 respectively, which are provided for this purpose with recesses serving to guide the ends of the cylinders. They are clamped in these recesses and/ or may be attached with the aid of cement.
  • These two transformers are mounted perpendicularly to one another in order to prevent them from reacting on one another.
  • That part which serves to supply the apparatus is mounted on the removable bottom 2 of the casing.
  • 20 denotes a supply transformer, H] a vacuum tube rectifier, and I9 filter condensers.
  • the supply transformer is mounted as remote as possible from the output transformer.
  • a casing construction for a radio receiver provided with a loudspeaker and other component parts said casing being made of moulded insulating material and comprising a front wall, top and side walls integral therewith, a partition of moulded insulating material disposed rearwardly of and parallel with the front wall, connecting members between said partition and front wall integrally formed therewith, an aperture in said partition for accommodating the loudspeaker, and means formed integral with the front wall and with the partition whereby the component parts of the receiver, such as the transformers and tube sockets, are capable of being supported thereon.
