Definitions

  • the present invention relates to a hermetically enclosed compressor according to DE-B-26 04 764.
  • 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.
  • This solution is represented by DE-A-31 42 773 with respect to the connections between relays, the starter and the thermal protection device.
  • 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 hermetically enclosed compressor similarly conceived for connection via a separate terminal strip or an integrated terminal strip, to permit the alternative employ of two integrated structures each having the same mechanical and electrical mounting base to be attached to the compressor, and an integral module including the starter, the thermal protection device and a protection cover, but having different systems for the electric connection to the remaining circuit components of the refrigerator.
  • the cable connection members comprise at least one integrated structure including a mounting base and a terminal strip, or alternatively an integrated structure including a mounting base 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.
  • 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 (not shown) thereof so that the latter extend through an opening 15 formed in mounting base 13.
  • Fig. 4 Also shown in Fig. 4 are the horizontally positioned starter 20 and the thermal protection device 21 housed respectively in suitable cavities of the dismountable support 26.
  • Support 26 is provided with a plurality of preferably internal contacts 31, the employ of which will be specified in the following.
  • a first element 22 acting as a connector-terminal unit is composed of external electrical terminals 23 arranged and disposed for being connected to corresponding external conductors, of internal electric connections 32 between said terminals 23, of at least one external contact 321, and of a tongue 27 and detent 28 mechanism for releasably mounting and positioning said element 22 in cooperation with a corresponding guide 29 and recess 30, respectively, provided on an angularly extending leg portion of mounting plate 13.
  • the mechanical configuration is selected so that, when element 22 is mounted on mounting plate 13, contact 321 is positively coupled to one of contacts 31.
  • a second dismountable element 24 is composed of a tongue and detent mechanism fully identical to the above described elements 27 and 28, and of one or several cable holder inserts for individually retaining the power supply and grounding conductors leading to the compressor, and to be manually connected in the conventional manner to contacts 31 and/or to contacts projecting from the rear part of one of the relays, e.g. relay 21.
  • the electric connection is automatically established either between contacts 321 and 31, or through a suitable connection between one of terminals 23 and one of the contacts projecting from the rear part of one of the relays, e.g. relay 21.
