行長さの減少化に大きく寄与している。What is important here is that, as is clear from FIG. 7, the position of the return spring 16 is behind the position where the screw hole of the terminal fitting 6 is provided. Therefore, the engagement point with the return spring 16 provided in the washer guide portion 13 becomes closer to the washer 12, and the dimension of the washer guide 13 in the front-rear direction becomes shorter. By the way, in the conventional example shown in FIG.
A return spring 44 is arranged on an axial extension line of the terminal screw 40, and the washer guide portion 42 includes the terminal screw 40 and the terminal metal fitting 41.
Since the terminal metal fitting 41 is supported by penetrating the terminal metal fitting 41 even in the state most distant from, the dimension of the washer guide portion is long. Another important thing is the washer 1
2 and the bending direction of the washer guide portion 13 and the axial direction of the torsion coil spring 16 are perpendicular to each other. By the way, in the conventional example shown in FIG. 3, these two directions are parallel to each other. These features of the present invention greatly contribute to the reduction of the depth of the entire terminal device.

る。FIG. 8 shows a method of assembling the return torsion coil spring 16. First, the washer guide 13 formed on the washer 12 of the terminal screw 9 with the washer guide portion is inserted into the washer guide groove 14 from the front of the terminal side housing 8, and the head of the terminal screw 9 is brought into contact with the finger protect portion 10. Next, the movable arm tip portion 16e of the torsion coil spring 16 is hooked on the washer guide portion notch portion 17 (A), the fixed arm 16b is twisted and inserted into the introduction path 19 (B), and the coil portion 16a is formed.
When is pushed inward, the tip portion 16d of the fixed arm engages with the locking portion 20, and at the same time the coil portion 16a fits in the support portion 18.

(1) When the wire is not wired, it can be immediately inserted into the space above the terminal fitting due to the force of the return spring and the wire can be immediately inserted. Because it automatically returns to the return state by force,
Wiring workability is good even when the device is attached closely.

を内蔵させることができる。(2) Since the terminal screw and the screw washer guide are held by the housing or the terminal fitting in the returned state, there is no risk of the terminal screw falling off or being lost. (3) Since the position in the front-rear direction where the terminal screw and the washer guide are provided and the position where the return spring is provided are juxtaposed at substantially the same position, the depth dimension of the entire terminal device is the same as that of the conventional product. It is possible to incorporate an automatic return mechanism for the terminal screw without increasing the number.

る。(4) The return spring storage space is opened in the rear surface of the terminal side housing, and as shown in the example of the assembling method, one arm tip of the torsion coil spring is hooked on the notch of the washer guide. After that, the assembling process of the return spring is completed only by sliding the tip of the other arm along the side surface in the accommodation space, so that the assembling work is very easy. This also facilitates automation of the assembly process.
