The invention refers to a mounting arrangement for the energizing cables of an electric motor of a refrigeration compressor, the electric motor being mounted in the interior of a casing of the compressor and the energizing cables presenting an end connected to the electric motor and an opposite end
The invention refers to a mounting arrangement for the energizing cables of an electric motor of a refrigeration compressor, the electric motor being mounted in the interior of a casing of the compressor and the energizing cables presenting an end connected to the electric motor and an opposite end operatively connected to an electric current power source, external to the casing, through the latter. The arrangement includes at least one immobilizing means mounted internally to the casing, so as to retain the energizing cables, maintaining at least part of the extension thereof in a predetermined positioning in the interior of the casing.

1. A mounting arrangement for the energizing cables of an electric motor of a refrigeration compressor, said electric motor being mounted in the interior of a casing of the compressor, said energizing cables presenting an end connected to the electric motor and an opposite end operatively connected to a power source external to the casing, through the latter, said arrangement comprising at least one immobilizing means mounted internally to the casing, so as to retain the energizing cables, and hold an elongated portion of the energizing cables in a predetermined position within the interior of the casing, said immobilizing means comprising a plurality of cradles, defined so that each energizing cable has its cross section at least partially lodged in a respective cradle disposed laterally adjacent to another energizing cable lodged in another adjacent cradle, the elongated portion of each energizing cable within the casing, the elongated portion being retained in at least one cradle, the cradles being arranged in at least one set of cradles, the cradles of one set being disposed laterally adjacent to one another, each cradle being defined between two cradle portions which laterally embrace and press a respective energizing cable, characterized in that the two cradle portions of each cradle are separate pieces, a first piece being affixed to the compressor, internally to the casing and the other piece being attached and pressed to the first piece by at least one gripping means, at least one of the first and second cradle portions presenting at least one recess to lodge a respective cross section portion of the energizing cable immobilized in said cradle, each recess of the first cradle portion having a depression disposed along a portion of the length of the cradle so as to present a curved profile extending along a portion of the length of the cradle, the depression adapted to hold a portion of said elongated portion so as to protect said elongated portion from bending forces which can break the electrical wiring of said energizing cable. 2. The arrangement, as set forth in claim 1, characterized in that the gripping means comprises a clamp, affixed in relation to the casing and to the first cradle portion and which is conformed to press the first cradle portion against the second cradle portion. 3. The arrangement, as set forth in claim 2, characterized in that the clamp is flexible. 4. The arrangement, as set forth in claim 1, characterized in that the first cradle portion is affixed to the casing of the compressor by at least one element defined by: screw, glue, rivet, welding. 5. A mounting arrangement for the energizing cables of an electric motor of a refrigeration compressor, said electric motor being mounted in the interior of a casing of the compressor, said energizing cables presenting an end connected to the electric motor and an opposite end operatively connected to a power source external to the casing, through the latter, said arrangement comprising at least one immobilizing means mounted internally to the casing, so as to retain the energizing cables, and hold an elongated portion of the energizing cables in a predetermined position within the interior of the casing characterized in that the immobilizing means comprises a single cradle defined so that the energizing cables have the cross section thereof at least partially lodged in the cradle, the single cradle having a depression disposed along a portion of the length of the cradle so as to present a curved profile extending along a portion of the length of the cradle, each energizing cable being laterally disposed to another adjacent energizing cable, the elongated portion of each of the energizing cables supported by the curved profile of the casing and being retained in the curved profile of the cradle. 6. The arrangement, as set forth in claim 5, characterized in that the cradle is defined between two cradle portions which laterally embrace and press the energizing cables. 7. The arrangement, as set forth in claim 6, characterized in that the two cradle portions of the cradle are separate pieces, a first piece being operatively affixed to the compressor, internally to the casing, and the other being attached and pressed to the first piece, by at least one gripping means. 8. The arrangement, as set forth in claim 7, characterized in that the gripping means comprises a pressure bolt. 9. The arrangement, as set forth in claim 7, in which the compressor carries, internal to the casing, an acoustic filter, the arrangement being characterized in that the first of the cradle portions is externally incorporated to the acoustic filter. 10. The arrangement, as set forth in claim 9, characterized in that the first cradle portion and the acoustic filter is formed as a unitary piece. 11. The arrangement, as set forth in claim 7, characterized in that each of the cradle portions of the cradle presents only one median recess to lodge a respective cross section portion of the energizing cables immobilized in said cradle. 12. The arrangement, as set forth in claim 1, characterized in that the first cradle portion includes a rear projection for anchoring and directing each energizing cable lodged in the recess of said first cradle portion, said rear projection extending beyond an end portion of the first cradle portion and free of the second cradle portion, the rear projection having a number of rear recesses corresponding with the plurality of recesses of the first cradle portion, and each of the rear recesses of the rear projection being aligned with a respective recess of the first cradle portion.
