Abstract
An electric connector for shielded cable, which improves the reliability of connection between a ground terminal and an external conductor and secures stable impedance characteristics. In this electric connector, a first housing is primarily molded on the external conductor, the external conductor is provided with a support protrusion that protrudes inside of the external conductor and contacts the ground terminal, and the second housing being secondarily molded is provided with a through hole, which is formed by a core pin that protrudes inwards from a mold and presses the ground terminal at a position where the second housing faces the support protrusion with the ground terminal in between.
Claims16
An electric connector for connecting shielded cable having a signal line and a ground line, the electric connector comprising:
- a conductive plate-shaped external conductor,
- an insulating first housing being primarily molded on the inside of the external conductor,
- a signal terminal having a contacting part at one end thereof, which contacts a counterpart terminal, and a barrel on the other end thereof, which crimps the signal line of the shielded cable, and being arranged on the inside of the first housing in one direction,
- a ground terminal having a contacting part at one end thereof, which contacts a counterpart terminal, and a barrel on the other end thereof, which crimps the ground line of the shielded cable, and being arranged on the inside of the first housing in the same direction as the signal terminal,
- a engaging mechanism for engaging the signal terminal and the ground terminal onto the first housing, and
- an insulating second housing being secondarily molded to sandwich the signal terminal and the ground terminal between itself and the first housing,
- wherein the external conductor is provided with a support protrusion, which is formed to protrude inside of the external conductor to contact the ground terminal, and the second housing is provided with a through hole, which is formed by a core pin that protrudes inward from a mold and presses the ground terminal, at a position where the second housing faces the support protrusion with the ground terminal in between.
