Electrical connector comprising a mat seal

An electrical connector comprising:

• an insulative housing having:
• a front face for being mated with a counterpart electrical connector, and
• a rear face for inserting cable terminals,
• a plurality of terminal accommodating chambers, which each open on the rear face for inserting of a respective cable terminal, and on the front face so that the respective cable terminal accommodated in the accommodating chamber can be connected to a counterpart terminal of the counterpart connector,
• a mat seal against the rear face, and having a plurality of cable passages facing the accommodating chambers,
• a rear grid disposed against the mat seal, and having a plurality of cable passages facing the cable passages of the mat seal, a mobile part,
• a guide rail fixed to the housing, the guide rail being transverse to the front-rear direction (XX′), for transversally guiding the mobile part, a ramp system such that, when the mobile part is guided by the guide rail, the ramp system pushes the rear grid against the mat seal so as to compress the mat seal
• the electrical connector being characterized in that the ramp system is formed by at least one chamgfered flange that rises rearward with respect to the rear grid and that is fixed to the rear grid.
