The pillar terminal 80 will be described with reference to FIGS.
The terminal frame 110 of the pillar terminal 80 is configured by a cylindrical body having a terminal frame through hole 111. That is, the terminal frame 110 is formed of a single metal plate, and includes a first upper surface portion (outer upper surface portion) 113, a first side surface portion 114 extending from the first upper surface portion 113, and a first side surface portion 114. A bottom surface portion 115 extending from the bottom surface portion 115, a second side surface portion 116 extending from the bottom surface portion 115, and a second top surface portion extending from the second side surface portion 116 and disposed inside the first top surface portion 113 ( Inner upper surface portion) 117. The first side surface portion 114 and the second side surface portion 116 are disposed to face each other. Further, the bottom surface portion 115 and the second top surface portion 117 are arranged to face each other. The first upper surface portion 113 is provided with an opening 113a. The second upper surface portion 117 is provided with a cylindrical protrusion, and a screw hole 112 is formed in the protrusion. The screw hole 112 is adapted to fit into the opening 113a. A terminal screw 100 is screwed into the screw hole 112.

  The bottom surface portion 115 is formed in an arc shape along the contact terminal portion 70. A terminal auxiliary plate 90 is inserted into the terminal frame through hole 111 of the pillar terminal 80. When the terminal screw 100 is screwed into the terminal frame 110, the distal end portion 101 of the terminal screw 100 comes into contact with the terminal auxiliary plate 90.

  Further, as shown in FIG. 8, the width D1 of the first upper surface portion 113 is larger than the width D2 of the terminal frame 110. That is, the distance D3 between the opening 113a formed in the first upper surface portion 113 and the edge of the first upper surface portion 113 is larger than that in the conventional pillar terminal where the protruding portion 113b is not provided. It has become. That is, the end portion of the first upper surface portion 113 protrudes outward from the second side surface portion. Hereinafter, a portion protruding from the terminal frame 110 in the first upper surface portion 113 is referred to as a protruding portion 113b.

The terminal auxiliary plate 90 will be described with reference to FIG.
The terminal auxiliary plate 90 is provided at the flat plate portion 91, a first side wall 92 provided at one side end of the flat plate portion 91 and extending perpendicularly to the flat plate portion 91, and the other side end of the flat plate portion 91.

In the flat plate portion 91, the terminal screw 100 abuts on the first surface 91 a on the side where the first side wall 92 and the second side wall 93 extend. The second surface 91b opposite to the first surface 91a contacts the electric wire 300. The length in the width direction of the first side wall 92 is longer than the length in the width direction of the flat plate portion 91 and is longer than the length in the width direction of the terminal frame through hole 111 of the terminal frame 110. The length in the width direction of the second side wall 93 is shorter than the length in the width direction of the terminal frame through hole 111 of the terminal frame 110. That is, when the terminal auxiliary plate 90 is set to make the flat plate portion 91 perpendicular to the screwing direction of the terminal screw 100, the first side wall 92 contacts the terminal frame 110.

With reference to FIGS. 10-12, the relationship between the blade receiving part 40, the pillar terminal 80, and the electric wire 300 is demonstrated.
As shown in FIG. 10, the terminal auxiliary plate 90, the electric wire 300, and the contact terminal portion 70 are disposed in the terminal frame through hole 111 of the terminal frame 110. As shown in FIG. 11, the contact terminal portion 70 is disposed on the bottom surface portion 115 side of the terminal frame 110, and the terminal auxiliary plate 90 is disposed on the second upper surface portion 117 side of the terminal frame 110. The electric wire 300 is inserted from below the terminal frame 110 and disposed between the contact terminal portion 70 and the terminal auxiliary plate 90. The bottom surface portion 115 of the terminal frame 110 and the contact terminal portion 70 are in contact with each other in the width direction. Since the contact terminal portion 70 is formed in an arc shape in a sectional view, the electric wire 300 is disposed at a substantially middle portion of the contact terminal portion 70. The terminal screw 100 is screwed in the longitudinal direction. The tip 101 of the terminal screw 100 pushes the terminal auxiliary plate 90. As shown in FIG. 12, the first side wall 92 of the terminal auxiliary plate 90 is in contact with the upper part of the terminal frame 110 so as not to fall downward.

According to the outlet A of the present embodiment, the following effects can be achieved.
(1) In the present embodiment, the first upper surface portion (outer upper surface portion) 113 of the terminal frame 110 is formed so as to protrude outward from the second side surface portion 116. Thereby, the space | interval D3 to the edge part of the opening 113a formed in the 1st upper surface part 113 and the 1st upper surface part 113 can be enlarged. For this reason, when the opening 113a is formed in the manufacturing process of the terminal frame 110, the portion between the edge of the opening 113a and the edge of the first upper surface 113 is less likely to be deformed.

  Further, the opening 113a and the screw hole 112 are enlarged, and the terminal screw 100 having a large diameter can be inserted into the terminal frame 110. Thereby, since the space | interval of the 1st side surface part 114 or the 2nd side surface part 116 of the terminal frame 110, and the side surface of the terminal screw 100 is narrowed, the electric wire 300 is less likely to be pinched by the said space | interval. That is, since it is suppressed that the electric wire 300 leaves | separates from on the contact terminal part 70 and enters into the said space | interval, it is suppressed that the contact with the electric wire 300 and the contact terminal part 70 becomes inadequate. In particular, when the electric wire 300 is composed of stranded wires, the effect is increased.

(2) In the present embodiment, the terminal auxiliary plate 90 that is pushed by the tip portion 101 of the terminal screw 100 is provided between the terminal frame 110 and the tip portion 101 of the terminal screw 100.
In the conventional pillar terminal in which the electric wire 300 is pressed by the tip portion 101 of the terminal screw 100, the electric wire 300 is pressed while being twisted by the tip portion of the terminal screw 100. Join. For this reason, there existed a possibility that the electric wire 300 might fracture. In this regard, according to the present invention, since the electric wire 300 is pressed by the terminal auxiliary plate, the electric wire 300 is pressed evenly as compared with the conventional pillar terminal in which the electric wire 300 is pressed by the tip of the terminal screw 100. can do. For this reason, the possibility that the electric wire 300 may break can be suppressed.

  (3) In this embodiment, the connection structure that connects the contact terminal portion 70 provided on the blade receiving spring 50 that receives the blade of the plug and the electric wire 300 is constituted by the pillar terminal 80 having the above structure.

  When the terminal screw 100 is screwed in, the first upper surface portion 113 may be deformed by a force applied to the first upper surface portion 113. In this regard, according to the present invention, since the distance between the opening 113a formed in the first upper surface portion 113 and the edge of the first upper surface portion 113 is increased, the strength of the portion increases, and the portion Can be suppressed. Thereby, the durability of the outlet A can be improved.

(4) In the present embodiment, the pillar terminal accommodating chamber 15 is provided with a fitting portion 15 a into which the protruding portion 113 b is fitted when the pillar terminal 80 is accommodated in the pillar terminal accommodating chamber 15.
According to this configuration, when the pillar terminal 80 is accommodated in the pillar terminal accommodating chamber 15, the protruding portion 113b of the terminal frame 110 is fitted into the fitting portion 15a. Therefore, as compared with the case where there is no such fitting portion 15a, The positioning accuracy of the pillar terminal 80 with respect to the pillar terminal accommodating chamber 15 when the pillar terminal 80 is accommodated in the pillar terminal accommodating chamber 15 can be increased.
