The invention relates to an electrical connector (2) including a connector body (20), which includes at least one accommodation (21), and at least two electrical connecting organs (22, 22′), which each include at least one internal section (220, 220′) extending inside said at least one accommodation (21). This electrical connector (2) is characterized in that it includes electrical insulating means (23), which have a tracking resistance index, CTI, higher than 600, which are located at least inside said at least one accommodation (21), which surround at least the internal section (220, 220′) of the at least two electrical connecting organs (22, 22′), and which extend at least over the internal section (220, 220′) of the at least two electrical connecting organs (22, 22′).
