[0002] In the existing IDC crimping connector, the inner wire end terminal usually includes a base, a piercing part and a connecting part; the piercing part and the connecting part are respectively fixed at both ends of the base. The piercing part is used to cooperate with the middle cover to accurately align the wire arrangement and pierce the outer surface of the wire arrangement to contact and electrically connect with its inner conductor, and the connecting part is used to contact and electrically connect with the board end terminal. In the actual production process, the connecting part is processed into a spring piece. One end of the spring piece is fixedly connected to the base, and the other end protrudes from the surface of the base to connect with the board end terminal. Since there is only one contact point between the spring piece and the board end terminal, when the contact point is damaged due to reasons such as elastic failure or offset of the spring piece, the electrical connection between the wire end terminal and the board end terminal is disconnected accordingly, resulting in poor contact reliability of the terminal and the connector.
