取り外すことが困難になるという欠点もあつた。 The washers built into conventional washer-embedded terminal screws are often flat, but in order to incorporate such washers so that they do not fall off the terminal screw, it is necessary to use a terminal screw blank with no threads formed yet. Another method is to insert a washer in which the inside diameter of the hole in the washer is slightly smaller than the outside diameter of the terminal screw, and then form the thread of the terminal screw by rolling. However, according to this method, the rolling tool used to form the threads of the terminal screw comes into contact with the bottom surface of the washer, so an incomplete thread is formed on the terminal screw starting from the bottom surface of the washer. . Therefore, due to this incomplete thread, there was a drawback that complete tightening was not possible, especially when attaching a thin electric wire or a thin plate-shaped object to be tightened. In addition, when installing electric wires, etc., there are cases in which the terminal screws with built-in washers are temporarily attached to the terminal board without attaching the electric wires, etc., but in such cases, it is necessary to completely remove the bottom of the terminal screws. Because of the screw threads, it was not possible to tighten the washer until it came into close contact with the terminal board, so there was a drawback that the terminal screw could become loose and fall off from the terminal board. Note that many of the washers built into conventional terminal screws with built-in washers are flat and rectangular, but in such terminal screws with built-in washers, when the terminal screw is unscrewed and removed, the washer is It rotates slightly along with the screw, and the washer comes into contact with the side wall of the mounting terminal plate. If the material of the terminal board to be installed is made of soft synthetic resin, etc., the corners of the flat square washer will dig into the soft synthetic resin, so do not remove the terminal screw from the installed terminal board. It also had the disadvantage of making it difficult.

構成されている。 The invention of the present invention is a washer-embedded terminal screw in which a washer 2 shown in FIG. 2 is assembled into a machine screw 1 shown in FIG. 1 as shown in FIGS. However, the machine screw 1 has a head peripheral projection outer diameter 4 slightly larger than the head outer diameter 3 on the seat side of the head, and a head peripheral edge having a slight thickness. It is equipped with a protrusion 5 and has a thread 6 completely formed,
The washer 2 has a U-shape as a whole, and has a bottom part 7 for tightening an object such as an electric wire, and two rising parts 8A and 8B to prevent the washer 2 from rotating with the machine screw 1. However, locking devices 9A, 9B, 9C, and 9D for preventing the washer 2 from falling off the machine screw 1 are constructed in parts of these two rising parts 8A and 8B. .

washer 2 is assembled into locking device 9A, 9 of washer 2.
As shown in FIGS. 3A and 3B, the terminal screw with built-in washer in the completed state is locked to the head peripheral protrusion 5 of machine screw 1 by B, 9C, and 9D. The device spacing 10 (9A and 9C, 9B and 9D) is slightly larger than the machine screw head outer diameter 3,
Moreover, since the outer diameter 4 of the circumferential protrusion of the head of the machine screw is made slightly smaller than the outer diameter 4, the washer 2 will not fall off from the machine screw 1. Further, the interval 11 between the two rising portions 8A and 8B of the washer 2 is slightly larger than the outer diameter 4 of the head peripheral protrusion of the machine screw 1, and
The distance 12 between the locking device and the bottom 7 is slightly larger than the thickness of the peripheral protrusion 5 of the head of the machine screw 1, and the inner diameter of the hole in the washer 2 is slightly larger than the outer diameter of the thread of the machine screw 1. Since it is made large, the washer 2 is in a loosely fitted state without falling off.

スに緩めたり、取り外したりすることもできる。 Next, the effects of the present invention will be explained with reference to FIG. 4, which shows a state in which an electric wire 13, which is an object to be fastened, is attached and tightened to a terminal plate 14 having a U-shaped groove using the washer-integrated terminal screw of the present invention. do. In the present invention, since the washer 2 is fitted into the machine screw 1 with the thread 6 completely formed, the incomplete thread part that occurs when the thread 6 of the machine screw 1 is rolled is formed by the thickness of the washer 2. It gets twisted and hidden, so
Since a complete thread 6 is formed immediately from the bottom surface of the washer 2, it is possible to completely tighten even thin wires or thin plate-shaped objects. In addition, even when temporarily attaching only the washer-incorporated terminal screw of the present invention without connecting the object to be fastened, the machine screw 1 has a complete thread immediately from the bottom surface of the washer 2, so that the washer 2 is attached to the terminal board. It can be tightened until it comes into close contact with the Therefore, the terminal screw does not become loose and fall off.
Furthermore, since the washer 2 has a U-shape, the rising parts 8A and 8B of the washer 2 come into contact with the side wall 15 of the U-shaped groove of the mounting terminal board, so the washer 2 does not rotate with the machine screw 1. Not only that, by configuring the heights of the rising parts 8A and 8B of the washer 2 to an appropriate height, even when the terminal screw is unscrewed and removed, the corner of the washer 2 will not touch the side wall 15 of the U-shaped groove of the mounting terminal board. Since there is no biting, the terminal screw can be smoothly loosened or removed while the washer 2 is assembled into the terminal screw 1.

きるとか等の多くの効果がある。 As explained above, the present invention overcomes the shortcomings of conventional terminal screws with built-in washers, such as the inability to tighten completely when attaching thin electric wires or thin plate-shaped objects, and the problem of temporarily attaching only the terminal screw to the washer. Even if the terminal screws are left in place, the terminal screws may become loose and fall off the mounting terminal board, or when the terminal screws are unscrewed and removed, the material of the mounting terminal board may be made of soft synthetic resin, etc. In this case, it not only solves the drawback that the terminal screws cannot be easily removed from the terminal board, but also allows the machine screws and washers to be assembled separately after being fabricated separately. Since it is possible to perform surface treatments such as plating, the finish such as plating is better than that of conventional terminal screws with built-in washers.Also, when installing washers, it is possible to adjust the spacing between the washer locking devices and the machine screw head. Since the difference between the outer diameter of the protrusion and the peripheral edge of the protrusion is small, it can be fitted extremely easily with little force, and has many advantages such as easy mass production and cost reduction.
