Since it is comprised as a thing and is formed from one member, compared with what is comprised by connecting a some member, there is no connection process etc., and manufacturing cost can be reduced.

  Furthermore, according to the present embodiment, in the outlet 1 from which the plug is inserted and removed, the contact terminal portion 32 and the electric wire 50 that are electrically connected to the blade receiving spring portion 31 that receives the blade of the plug are connected to the above-described pillar terminal 19. It is possible to provide an outlet that can prevent the electric wire 50 from entering between the outer peripheral surface of the terminal screw 21 and the inner surface of the terminal frame 20. A stable contact with the terminal portion 32 can be ensured.

  By the way, this embodiment is not limited to the above-mentioned description, For example, you may actualize as follows. As a configuration of the pillar terminal instead of FIG. 6 and FIG. 7, as shown in FIG. 9 and FIG. 10, a terminal auxiliary plate 60 that presses an electric wire (not shown) may be further provided. The terminal auxiliary plate 60 is disposed between the distal end portion 21 a of the terminal screw 21 and the electric wire, and is pushed by the terminal screw 21. As shown in FIG. 11, the terminal auxiliary plate 60 includes a base 61 extending in the vertical direction of the outlet 1 in the terminal frame 20, and a terminal screw 21 side in the longitudinal direction of the outlet 1 from both vertical ends of the outlet 1 in the base 61.

Therefore, it becomes possible to suppress that the contact pressure of the said electric wire and the contact terminal part 32 falls.

  More specifically, in the comparative example shown in FIG. 12, the electric wire 66 moves in the width direction of the outlet 1. That is, it is difficult to fix the position of the electric wire 66 because the contact terminal portion 65 is flat. That is, when the terminal screw 21 is pressed, the electric wire 66 moves toward the end of the terminal frame 20 in the width direction of the outlet 1, and the contact pressure is lowered, so that the contact stability is lowered.

  On the other hand, the pillar terminal of the present embodiment shown in FIGS. 9 and 10 includes a terminal auxiliary plate 60 formed so as not to come into contact with each protrusion 46 inside the terminal frame 20, thereby making contact. The electric wire can be held between the terminal portion 65 and the terminal auxiliary plate 60.

  Therefore, according to the pillar terminal shown in FIG. 9 and FIG. 10, it is arranged between the tip portion 21 a of the terminal screw 21 and the electric wire, and is pressed by the terminal screw 21, thereby holding the electric wire between the contact terminal portion 65. By providing the terminal auxiliary plate 60 to be moved, the terminal auxiliary plate 60 moves together with the terminal screw 21 and the terminal auxiliary plate 60 presses the electric wire, so that the contact pressure between the electric wire and the contact terminal portion 65 is reduced. This can be suppressed.
