Modular jack having built-in circuitry

A modular jack comprising:

• a main housing member having a chamber and a rearward opening leading into said chamber;
• a contact array including a row of contact pins formed therein, each contact pin having a first portion and a rearwardly extending portion;
• a mounting array including a row of mounting pins formed therein, each mounting pin having a downwardly extending portion and a rearwardly extending portion, said mounting array further including a rearwardly extending platform projecting in the same direction as said rearwardly extending portions of said contact pins and said mounting pins;
• a printed circuit board having a transmit circuit and a receive circuit, said printed circuit board further having a first and a second row of vias formed therethrough, said first and said second row of vias each being separated from a bottom edge of said board by a first and a second distance, respectively;
• and
• a rear housing member;
• said row of contact pins having a spacing from said platform substantially equal to said first distance;
• said row of mounting pins having a spacing from said platform substantially equal to said second distance;
• said printed circuit board being coupled to said rows of contact pins and mounting pins at said first and second rows of vias, respectively;
• said rear housing member engaging said platform, thereby enclosing said printed circuit board.

A modular jack comprising:

• a housing having a forward aperture opening into a receiving cavity, said housing further having a rear opening;
• a plurality of contact pins, each contact pin having a portion projecting into said receiving cavity and a rearward portion projecting away from said rear opening;
• a plurality of mounting pins disposed within said housing and in spaced relation with respect to said contact pins, each mounting pin having a rearward portion projecting away from said rear opening;
• and
• a printed circuit board having a first and a second plurality of pin connection locations and further having electronic circuitry including a transmit circuit and a receive circuit, each said transmit and receive circuit including a signal wave shaping circuit, an isolation transformer and a common mode choke coil;
• a mounting pin sub-assembly containing said mounting pins;
• said sub-assembly further having a platform extending beneath said rearward portions of said mounting pins;
• said printed circuit board having a bottom edge;
• said rearward portions of said contact pins being spaced apart from said platform by a distance approximately equal to a distance of separation between said first pin connection locations and said bottom edge;
• and said rearward portions of said mounting pins being spaced apart by a distance approximately equal to a distance of separation between said second pin connection locations and said bottom edge;
• said rearward portions of said contact pins electrically coupled at said first pin connection locations;
• said rearward portions of said mounting pins electrically coupled at said second pin connection locations;
• whereby said electronic circuitry of said printed circuit board provides electrical continuity between said contact pins and said mounting pins.
