A vehicle diagnostic interface module comprising: - a protective outer casing, - an electronic module which is provided with at least one printed circuit board arranged inside said protective outer casing, and - a connector provided with a plate-like contact-carrier socket, which is coupled to said outer casing and is arranged parallel to said printed circuit board orthogonal to a longitudinal reference axis, and comprises an inner face facing to said printed circuit board; said connector further comprising a collar projecting from an opposite outer face of said socket; said printed circuit board having a first larger face adjacent to said inner face of the socket; said vehicle diagnostic interface module being characterized in that it comprises a plurality of rigid pins which are integrated into said socket; each rigid pin is shaped so as to comprise: a first segment which projects from said inner face of the socket in order to be parallel to said longitudinal axis orthogonal to said printed circuit board; a second segment that projects from said outer face of said socket opposite said inner face so as to protrude/extend within said collar while remaining parallel to said longitudinal axis; and a central intermediate segment which is integrated into said socket and extends within said socket along a direction transverse to said longitudinal axis; wherein said pins are integrated into said socket so as to form two parallel rows of second segments facing each other on said outer face and two parallel rows of first segments facing each other on said inner face of said socket; said socket and said printed circuit board are substantially rectangular; said two rows of first segments are arranged on the respective opposite larger sides of said printed circuit board, these larger sides being, in turn, arranged parallel and adjacent to the opposite larger sides of said socket; said first segments being inserted in notches formed on said opposite larger sides of said printed circuit board, where they are electrically coupled to said printed circuit board. - a protective outer casing, - an electronic module which is provided with at least one printed circuit board arranged inside said protective outer casing, and - a connector provided with a plate-like contact-carrier socket, which is coupled to said outer casing and is arranged parallel to said printed circuit board orthogonal to a longitudinal reference axis, and comprises an inner face facing to said printed circuit board; said connector further comprising a collar projecting from an opposite outer face of said socket; said printed circuit board having a first larger face adjacent to said inner face of the socket; a first segment which projects from said inner face of the socket in order to be parallel to said longitudinal axis orthogonal to said printed circuit board; a second segment that projects from said outer face of said socket opposite said inner face so as to protrude/extend within said collar while remaining parallel to said longitudinal axis; and a central intermediate segment which is integrated into said socket and extends within said socket along a direction transverse to said longitudinal axis; wherein said pins are integrated into said socket so as to form two parallel rows of second segments facing each other on said outer face and two parallel rows of first segments facing each other on said inner face of said socket; said socket and said printed circuit board are substantially rectangular; said two rows of first segments are arranged on the respective opposite larger sides of said printed circuit board, these larger sides being, in turn, arranged parallel and adjacent to the opposite larger sides of said socket; said first segments being inserted in notches formed on said opposite larger sides of said printed circuit board, where they are electrically coupled to said printed circuit board.
