  • this female electrical connector 3 comprises (as mentioned above), on the one hand, a female connector body 30 which comprises at least one housing 31 and, on the other hand, at least one electrical connection member female (32, 32 ') more particularly at least two female electrical connection members (32, 32').
  • Such a female electrical connection member (32, 32 ') each comprises an internal section (320, 320') extending inside the female connector body 30, more particularly inside said at least one accommodation 31.
  • this female electrical connector 3 comprises the electrical insulation means 33 which surround, then and as described above, the internal section (320, 320 ') of said at least one female electrical connection member (32 , 32 '), more particularly the internal section (320, 320') of said at least two female electrical connection members (32, 32 ').
  • These electrical insulation means 33 extend, then and as described above, over the internal section (320, 320 ') of said at least one female electrical connection member (32, 32') more particularly by above the internal section (320, 320 ') of said at least two female electrical connection members (32, 32').
  • these electrical insulation means 33 extend, again, to the front of the internal section (320, 320 ') of said at least one female electrical connection member (32, 32'). This advantageously allows these electrical insulation means 33 of the female electrical connector 3 to cooperate with the electrical insulation means 23 of the male electrical connector 2. This results in continuity of the electrical insulation means (23; 33). between the rear end 202 of the male electrical connector 2 and the rear end 302 of the female electrical connector 3 and, thus, continuity in the electrical insulation between this rear end 202 of the male electrical connector 2 and this rear end 302 of the connector female electric 3.
  • Said at least one female electrical connection member (32, 32 ') is, in fact, each constituted by a female connection socket.
  • Such a female connection socket is configured to cooperate with one of the male connection pins mentioned above.
  • the invention relates to an electrical connection device 1 comprising, on the one hand, a male electrical connector 2 and, on the other hand, a female electrical connector 3.
  • the male electrical connector 2 has the characteristics described above and, on the other hand, the female electrical connector 3 has the characteristics described above.
  • the electrical insulation means 23 of the male electrical connector 2 are located in the extension of the electrical insulation means 33 of the female electrical connector 3 and cooperate with these electrical insulation means 33 of the female electrical connector 3.
