Cooling compressor comprising protection arrangement for electrical connections
The present invention pertains to the technological field of cooling compressors and, more specifically, relates to an anti-flame protection arrangement for the electrical connections of said cooling compressor. 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.
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.
