Patent ID: 7988465

Claim:
A circuit board based connector, comprising: a circuit substrate having an end that is provided with a plurality of conductive terminals, a plurality of flat cable connection terminals being formed on an end of the circuit substrate that is opposite to the conductive terminals for connection with a flat cable, the circuit substrate having a first surface and a second surface, an insulation layer being formed on the first surface of the circuit substrate, at least one projection section being formed on the insulation layer of the first surface of the circuit substrate and the projection section being raised above a reference datum plane defined by the first surface of the circuit substrate by a predetermined height and extends on the reference datum plane in a direction toward a location adjacent to the conductive terminals of the circuit substrate, whereby when the circuit substrate is inserted into an insertion space defined in a connection socket with the conductive terminals thereof, at least a local zone defined by the projection section is put into engagement with and thus retained by opposite walls of the insertion space of the connection socket; a first shielding layer that overlaps the projection section; and a second shielding layer that is formed on the second surface of the circuit substrate, the first shielding layer and the second shielding layer being connected to a preset grounding pattern through a via defined through the circuit substrate and a conductive substance being formed on an inside surface of the via.
