It thus forms a complementary means for holding the cables and their sheaths, received and guided in each of these gutters 23a, 23b, 23c.
  • connection terminals 5a, 5b, 5c do not pass through the bottom wall 160 of the base 1 carrying the skirt 14: this allows electrical insulation complementary to these connection terminals with respect to the other elements received in the compressor housing.
  • the connector 100 therefore makes it possible to simply make a safe and reproducible connection between the connection terminals 5a, 5b, 5c of the control module and the connection terminals 4a, 4b, 4c which equip the ends of cables coming from the motor electrical controlled by this control module.
  • the embodiment of the dielectric element 3 in monobloc form allows a quick and easily reproducible assembly of this connector, in particular thanks to the cavities and coding pins, respectively referenced 33 and 22.
  • the presence of the appendix 32 arranged on the dielectric element monoblock 3 is, in addition, an additional keying means during assembly of the connector 100, while allowing a quick and effective visual control of the integrity of this connector.
  • the interposition of the monobloc dielectric element generates a barrier which opposes the presence of PAG oil between the partition and the elements carried at high electrical potentials and present in the connector of the invention.
  • the monobloc dielectric element also increases the distance between this partition and these elements.
  • the invention can not be limited to the means and configurations described and illustrated here, and it also extends to any equivalent means or configurations and any technically operating combination of such means.
  • the invention has been described here in the context of an electric motor powered by three-phase current, it applies to any type of motor, by adjusting the number of receiving housings arranged in the base 1 and, consequently, by adjusting the number of orifices arranged in the same base 1, the number of recesses arranged in the monobloc dielectric element 3, the number of holes of which the cover 2 is provided and the number of gutters configured in the same cover 2.
  • these receiving housings, orifices, holes, recesses and gutters are, according to the invention, in number equal to the number of cables necessary for the power supply of the motor and the number of connection terminals of the housing constituting the electrical component supplied via this connector according to the invention.
