Electrical connector having an inner printed circuit board

An electrical connector mounted on an external printed circuit board, comprising:

• an insulative housing having a front mating face extending in a first direction, a
• mounting face, and a receiving cavity extending through the mounting face;
• an inner module received in the receiving cavity, comprising:
• a front contact module having a front insulative block defining a first insulative groove and a plurality of front contacts mounted thereon;
• a rear contact module having a rear insulative block defining a second elongated groove and a plurality of rear contacts mounted thereon and extending beyond the mounting face for being mounted on the external printed board;
• and
• an inner printed circuit board extending along a lengthwise direction of the housing perpendicular to the first direction and inserted into both the first elongated groove and the second elongated groove to be fixed between the front insulative block and the rear insulative block,
• a pair of protrusions extending from a rear end of the front insulative block and a front end of the rear insulative block, respectively, said first and second elongated grooves being defined in an inner side of each protrusion, opposite side edges of the inner circuit board are inserted into opposite grooves of the front insulative block and the rear insulative block and supported by the front insulative block and the rear insulative block, thereby fixing the inner circuit board reliably and ensuring electrical connection between the front contacts and the rear contacts.

• and
• an inner printed circuit board located between the front insulative block and the rear insulative block and electrically connecting the front contacts with the rear contacts;
• wherein the front contacts extend along a first direction in a top view, the rear contacts extend along a second direction in said top view under a condition that said first direction is oblique to said second direction in said top view;
• wherein
• the mating face is oblique to the mounting face in said top view under a condition that the mating face is essentially perpendicular to the first direction, and the mounting face is essentially perpendicular to the second direction.
