ならなかつた。"Problem to be solved by the invention" In the conventional terminal screw holding device, the terminal screw 104
After inserting the terminal into the mounting hole 103 of the washer 101, a caulking process is required. Also, if the threads on the terminal screw 104 are damaged, the terminal screw 104 is caulked and integrated with the washer 101, so the terminal screw 104 alone is necessary. Therefore, the entire assembly including washer 101 had to be replaced.

当たり外れることを阻止する。 In FIG. 3, a procedure for assembling the washer 11 holding the terminal screw 1 as described above into the terminal block 21 will be explained. A washer 11 is slidably mounted on an insulating terminal block 21 by compressing a coil spring 22 at the bottom of a vertical piece 13, and a terminal plate 24 with screw holes 23, 23 carved therein is attached to the terminal screws 1, 1. They are supported by the terminal block 21 so as to face each other. Horizontal piece 12 of washer 11
is biased upward by the coil spring 22 to create a gap between the lower end of the terminal screw 1 and the upper surface of the terminal plate 24 to facilitate insertion of the crimp terminal at the tip of the wiring, and insert the crimp terminal into the screw hole 23 of the terminal plate. The wiring can be attached to the terminal board 24 simply by placing the terminal screw 1 on the terminal board 24 and pushing down the terminal screw 1 against the biasing force of the coil spring 22 and screwing it into the screw hole 23. A terminal block 21 incorporating the washer 11 holding the terminal screw 1, the coil spring 22, and the terminal plate 24 as described above.
A few of them are overlapped and connected, and a transparent cover 26 made of synthetic resin is fitted to the upper end of the upright substrate 25.
Since the terminal screw 1 held by the washer 11 has the protrusion 15 located within the annular groove 5 of the terminal screw 1, it does not normally come off. However, if the guide groove 4 of the terminal screw 1 and the protrusion 15 of the washer 11 match, there is a risk that it will come off, but even when the terminal block 21 is turned sideways or diagonally downward, the head 3 of the terminal screw 1 may be covered. 26 to prevent you from hitting or missing.

カシメに比して安価に製作できる。"Effects of the Invention" As described above, the present invention provides a terminal in which a guide groove 4 or a deletion surface 7 is formed on the outer periphery of the shaft portion 2 over the entire length in the axial direction, and an annular groove 5 is carved under the neck of the head 3. The guide groove 4 or removal surface 7 of the terminal screw 1 is inserted into the mounting hole 14 of the horizontal piece 12 that receives the screw 1 and the shaft portion 2.
The shaft part 2 of the terminal screw 1 is inserted into the mounting hole 14 of the horizontal piece 12 of the washer 11, and the horizontal piece 12 is inserted into the annular groove 5. This terminal screw holding device is installed in such a way that the terminal screw 1 can be rotated with respect to the washer 11 and cannot be moved forward or backward, and a crimping process is not required to install the terminal screw in a manner that the terminal screw can be rotated with respect to the washer 11 but cannot be moved forward or backward. Furthermore, even if the thread of the terminal screw is damaged, only the terminal screw can be replaced without replacing the entire device including the washer.
Instead of the conventional crimping process, a guide groove or cut-out surface is simply formed on the terminal screw, and only a protrusion or fitting surface that fits into the washer is formed on the washer, so it can be manufactured at a lower cost than crimping.
