Further, the first tightening portion 12 is provided with a wire penetration portion 122 at the upper end of the wire tightening groove 121. When the wire is inserted into the conductive terminal 10, the wire penetration portion 122 penetrates the insulating layer of the wire to expose the conductor of the wire, and when the conductor is further inserted into the wire clamping groove 121, the conductor becomes conductive.

Extending diagonally towards each other in different directions. As shown in FIGS. 5 and 7, in the exemplary embodiment, the insulating housing 20 is disposed at the other end of the mounting groove 23 opposite the end where the first insertion slot 24 is located. A second insertion slot 27 is further included. When the conductive terminal 10 is mounted in the insulating housing 20, the space between the second tightening portions 13 communicates with the second insertion slot 27. A mating conductive terminal configured to mate with the conductive terminal 10 can be inserted into the second insertion slot 27 and tightened by the second clamping portion 13 so that the conductive terminal 10 It is electrically connected to the conductive terminal.

  Further, as shown in FIG. 4, in the exemplary embodiment, the end portions of the pair of second tightening portions 13 have protrusions 131 protruding toward each other in order to firmly tighten the mating conductive terminal. Provided.
