An electrical arrangement assembly is provided on the external region of a hermetic housing of a compressor. The arrangement includes an insulating box capable of housing an electrical interface between internal and external regions of the compressor including an insulating box coupled to the external region by means a hinge element having a pivot handle with an extension and a grounding tab. The grounding tab of the hinge element cooperates with a housing cradle of the insulating box when connecting the box to the housing of the compressor. A controlled angular movement between the insulating box and the hinge element results in electrical connection between a first and second set of electrical terminals of the electrical interface between the internal and external regions of the hermetic housing of the compressor.

Is disclosed an electrical grounding assembly arrangement for reciprocating compressor capable of optimizing the assembly of the electrical grounding connection and allows a quick visual inspection of the same, while providing a saving of electrical conductors, which are nonexistent in light of the invention in question. For this purpose, the casing (of the frequency inverter, which is fixed to the external region of the compressor housing) includes an electrical grounding bus capable of receiving, on its external portion, a fixing metal element specially adapted to electrically connect the outer portion of the electrical grounding bus and the electrical grounding connection of the housing and, at the same time, mechanically fixing the casing to the reciprocating compressor housing by physically locking the external portion of the electrical grounding bus and the electrical grounding connection of the housing.

A constructive arrangement introduced in a housing for electronic circuit with power components is disclosed, in which a modular frame structure is provided, capable of being attached to the main structural frame and responsible for receiving the heat sink element. Said frame structure further includes holes bordered by contour walls, which optimize the application of high thermal conductivity coefficient resin between the electrical/electronic power components of the circuit board and the heat sink element.
