ている。On the other hand, as shown in FIG. 3, the end of the bottom surface of the terminal fitting 4 located on the opening side of the body 1 has a width substantially equal to the width of the narrow portion 8 of the terminal seat 6. A width notch 12 is formed. Further, as shown in FIGS. 1 and 2, a recess 13 is formed on the opening side of the base body 1 of the base 2. Then, the narrow portion 8 of the terminal seat 6 is connected to the notch 12 of the bottom surface of the terminal fitting 4.
The terminal seat 6 is fixed to the base 2 by the screw 14 in a state in which the downward bent piece 7 of the tip of the terminal seat 6 is fitted into the recess 13 of the base 2. As a result, the end of the terminal seat 6 on the opening side is fixed to the terminal fitting 4,
Further, since the end portion on the opposite side is fixed to the base 2, the terminal seat 6 is reliably prevented from rising. Further, since the upper surface of the terminal fitting 4 is pressed by the rib 15 of the cover 3, the terminal fitting 4 itself is completely prevented from rising.

The terminal seat 6 is fixed to the terminal fitting 4 with the bent piece 7 fitted in the recess 13 of the base 2. However, in this embodiment, the inner end 16 of the terminal seat 6 having the inner conductor 11 welded to the back surface is raised upward,
The terminal fitting 6 is located on the lower surface of the top plate to prevent the terminal seat 6 from being lifted up inside. Further, the lifting of the terminal fitting 4 itself is prevented by pressing the upper surface of the terminal fitting 4 by the rib 15 of the cover 3 as in the first embodiment.

導体17を端子座６に押圧するようにしてもよい。In the terminal device of the present invention thus constructed, the tip of the outer conductor 17 is inserted into the box-shaped terminal fitting 4 from the opening side of the body 1, and as shown in FIG. It is the same as the conventional one in that 17 is pressed against the upper surface of the terminal seat 6 by the terminal tightening screw 18. However, in the present invention, the bent piece 7 at the end of the terminal seat 6 on the opening side is engaged with the bottom surface of the terminal fitting 4, and the bent piece 7 is also fitted into the recess 13 of the base 2. Therefore, the terminal seat 6 and the terminal fitting 4 can be easily and surely fixed to the base 2, and the terminal seat 6 does not float up unlike the conventional case. Therefore, the work of inserting and attaching the outer conductor 17 can be performed smoothly, and even if a force is applied to the outer conductor 17, the terminal seat 6 is not likely to be deformed. In the above embodiment, the outer conductor 17 is attached to the terminal seat 6 by the two terminal tightening screws 18.
However, the outer conductor 17 may be pressed against the terminal seat 6 by one terminal tightening screw 18.
