IDC connector assembly

An insulation displacement connection (IDC) connector assembly for being mounted to a printed circuit board (PCB), comprising:

• an IDC connector comprising:
• a housing defining a hollow portion having an entrance and an exit;
• a terminal received in the hollow portion and having a solder portion extending outside the exit of the hollow portion and adapted to be soldered to the PCB, a pair of arm portions extending into the hollow portion, and a pair of head portions respectively formed on the arm portions;
• and
• a wire extending into the hollow portion of the housing from the entrance to be located between the pair of arm portions, the pair of head portions piercing into the wire so that electrical connection is established between the wire and the terminal;
• wherein each head portion comprises a plurality of barbs extending inwardly and a projection extending upwardly;
• wherein the housing has a pair of shaped side portions, each shaped side portion comprises an incline and a concavity above the incline, and the projection of the head portion is slidable along the incline and is received into the concavity so that the barbs pierce into the wire;
• wherein each head portion has a tail positioning portion below the projection of the head portion and extending downwardly, the shaped contour further comprises a groove at a lower end thereof, and the tail positioning portion is received into the groove when the terminal dielectrically connects with the wire.
