Problem to be solved: Ensure end-user safety of the compressor through a simple and inexpensive solution and preventing the maintenance and/or propagation of flames/fire in the region of the chamber defined by the protective cover of the electrical connections external to the compressor housing. Problem resolution: Accordingly, it is provided a cooling compressor including a protection arrangement for electrical connections integrated by a protective cover defining an electrical connections chamber external to the housing, the protective cover being physically associated with an anti-flame body, which defines a sealing portion, preferably making the electrical connections chamber hermetic in relation to an external environment. ## Claims ### Claim 1 Cooling compressor comprising protection arrangement for electrical connections, said cooling compressor including: a housing; a compression mechanism disposed within the housing; an electric engine capable of actuating the compression mechanism; a set of electrical terminals, said set of electrical terminals being physically associated with a wall of the housing; a protective cover defining an electrical connections chamber external to the housing, being that said electrical connections chamber accommodate the set of electrical terminals and power supply plugs that connect electrically to the set of electrical terminals and energize the electric engine; said cooling compressor characterized by the fact that: the protective cover is physically associated with an anti-flame body defining a sealing portion; said anti-flame body being capable to prevent the exchange of gaseous fluids from the interior of the electrical connections chamber with the external environment. ### Claim 2 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the protective cover is physically associated with an anti-flame body defining a sealing portion, being capable of rendering the electrical connections chamber hermetic in relation to an external environment. ### Claim 3 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body prevents the entry of oxygen to the interior of the electrical connections chamber and prevents the outlet of coolant fluid from said electrical connections chamber. ### Claim 4 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is flexible. ### Claim 5 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body covers, at least partially, the protective cover. ### Claim 6 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is disposed adjacent to an outer face of the protective cover, externally to the electrical connections chamber. ### Claim 7 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is disposed adjacent to an inner face of the protective cover, internally to the electrical connections chamber. ### Claim 8 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is disposed at the interface between the protective cover and the housing of the compressor, directly or indirectly. ### Claim 9 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is made of a polymer material among the group of: thermoplastic, elastomer, heat shrinkable. ### Claim 10 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is overinjected to the protective cover. ### Claim 11 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is assembled by interference adjacent to the protective cover. ### Claim 12 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body comprises a ring, glove or cup shape. ### Claim 13 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body comprises a shape and/or contour analogous to that of the protective cover. ### Claim 14 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is capable of preventing the entry of oxygen existing in the external environment to the interior of the electrical connections chamber. ### Claim 15 (depends on 1) Cooling compressor comprising protection arrangement for electrical connections, according to claim 1, characterized by the fact that the anti-flame body is capable of preventing the exit of any flames or sparks generated in the interior of the electrical connections chamber to the external environment.
