Definitions

  • the present invention relates to an electric connection system for a hermetically enclosed compressor for use in domestic refrigerators for the preservation of foods, or in other appliances requiring the employ of a hermetically enclosed compressor.
  • the innumerable possibilities of designing an electric circuit for a domestic refrigerator manufactured on an industrial scale may be basically reduced to just two alternative arrangements: the first of these arrangements is directed to the provision at any suitable location within the refrigerator of a suitable terminal strip or box so as to be accessible from the exterior, usually from the rear of the refrigerator.
  • terminal box or strip Combined in this terminal box or strip are the terminals of all the electric component circuits of the refrigerator, the terminal box or strip being internally provided with means for interconnecting the various component circuits so as to result in a unitary circuit.
  • the terminal box or strip is finally connected to an external power supply cable to thereby complete the wiring of the refrigerator.
  • the second arrangement proceeds from the recognition that the compressor is usually provided with certain electric components associated and connected thereto in a perman­ent manner and required for ensuring proper operation of the compressor, typically a starter and a thermal protect­ion device.
  • the present invention is therefore directed to the obtent­ion of the following advantages:
  • a domestic refrigerator comprising a compressor installed in its interior so as to be partially accessible from the rear of the refrigerator, and electrically connected to the remainder of the electric circuit by releasable connection means.
  • connection means comprise at least one integrated structure including an electric component module and a terminal strip, or alternatively an integrated structure including an electric component module and a cable clamping insert, said integ­rated structures being adapted to be mechanically mounted in an interlocking fit on a metallic base formed by punching and bending a sheet metal blank and permanently secured to the compressor adjacent the hermetically sealed connection terminal thereof.
  • the integrated structure including the module and the terminal strip is preferably conceived so that the terminal strip is accessible from outside in a position and at an orientation permitting connector means to connected thereto by an automatized operation.
  • the synthetic material of which the module is composed is required to have particularly exacting properties, and is thus more expensive than the synthetic material osed for the terminal strip.
  • a domestic refrigerator presents, when viewed from the rear, a lower cavity 1 housing a compressor 2 with its external components 3 and the delivery and return pipes 4 and 5, respectively, of the refrigerant circuit. Also diagrammatically shown are a condenser 6 and a capillary 7.
  • the refrigerator further includes a terminal strip or box 8, an external power supply cable 9, a connection 10 leading from terminal strip 8 to compressor 2, and a number of connections 11, 12 leading from terminal strip 8 to other electrical components of the refrigerator.
  • a metallic mounting base 13 suitably welded to the outer casing 14 of the compressor adjacent the power supply terminals thereof so that the latter extend through an opening 15 formed in mounting base 13 (Fig. 5).
  • a projecting portion 16 of mounting base 13 is formed with a ledge ot tongue 17 to be used as a guide and support element, and an opening 18 for interlockingly receiving therein a stud provided on the integrated structure to be described.
  • Mounting base 13 is also provided with a terminal 19 to be employed for connecting compressor casing 14 to ground.
  • a horizontally disposed starter 20 and a thermal protection device 21 are shown in fig. 2 .
  • the integrated strusture further includes an external portion 22 acting as a terminal strip.
  • the terminal strip is provided with external electric terminals 23 formed and arranged in the manner of connector contacts and adapted to have a complementary external connector connected thereto in a fully automatized operation.
  • the external portion of the integrated structure is not formed as a terminal strip, but rather as a cable clamping insert 24 conceived to retain the power supply and grounding cables of the compressor to be connected thereto by a conventional manual operation.
  • fig. 4 shows an exploded perspective view of the electromechanic components to be mounted on the compressor, specifically the mounting base 13, the module 26 composed of thermal protection device 21 and starter 20, the electric connector or terminal strip 23, and as an aletrnative to the latter, the cable clamping insert 24.
  • Figs. 5, 5a, 5b and 5c finally show various embodiments of mounting base 13 designed to offer maximum flexibility for mounting the electric components by modifying the shape and locations of the guides and mounting positions without however varying the location and the dimensions of the connection between mounting base 13 and compressor casing 14.
