いる。2. Description of the Related Art Switchboards and various types of electric equipment are provided with a ground for connecting a part of the equipment to the ground in order to prevent electric shock due to static electricity or electric leakage. For home appliances,
Usually, there is only one ground, and therefore there is only one ground terminal. However, many industrial electrical devices are large, so that the number of ground terminals is 20 to 3 per device.
As many as 0 places. These grounding terminals are usually mounted inside the housing of the device, but the door of the housing is often opened on a daily basis, and therefore, the inside is often painted. As shown in FIG. 12, a seal with an earth mark is attached near the ground terminal in order to clearly indicate the position of the terminal in accordance with the regulations for electric work.

合いが悪かった。However, many of the coatings are insulative, which hinders grounding. Nevertheless, the inner surface of the screw hole on the housing side is a slightly exposed portion of the metal, so that it is energized and somehow the earth is working. However, the inner surface of the screw hole is often covered with paint, and there is a problem that a good ground cannot be obtained. And, since the earth leakage does not always occur, such a problem is not immediately surfaced as an accident, but has been regarded as a serious problem, possibly including the possibility of the accident. or,
Even if a certain degree of conductivity is obtained, it is said that the earth having no electrical resistance has a higher grounding performance, so that the electrical resistance due to the coating of the housing is very inconvenient. In addition, it is required by the electrical work regulations to attach a ground seal near the terminals. However, if the wiring is crowded, it is difficult to secure a place to apply the sticker, and the sticker is visible. Was difficult and I was sick.

Then, the mounting member is turned together with the screw while the mounting member is pressed by the housing through the ground terminal by the head of the screw because the protrusion of the through hole is engaged with the engagement groove of the screw. . With this configuration, the paint on the housing is shaved by the file portion provided on the bottom surface, and the eyes of the file are pressed by the housing and crushed, so that the ground terminal is finally substantially flush with the bottom surface and attached. At this time, since the paint on the housing has been scraped off and the bottom surface is substantially flush with the housing and is pressed against the housing, the conductivity of the contact surface between the housing and the mounting member is increased. Conductivity increases. Also, the coating can be cut at the same time as the screw tightening work for attaching the ground terminal.

In addition to the effects of claims 1 to 3, it is possible to provide an earth mark on the cover in advance. As a result, the cover part can also serve as a conventional earth seal, so that the work of attaching the earth seal during the mounting operation can be omitted. Along with this, with the conventional earth seal, it was difficult to re-attach when mistakenly affixed, but the earth terminal cover of the present application does not have such difficulties. There is no need for alignment. Of course, even if the cover is not covered by the earth mark, the seal can be attached to the ground terminal cover after installation, and it is to be attached directly above the terminal, even in places where wiring is crowded. There is no need to secure a place to attach. Further, since the cover itself functions as a mark of the position of the ground terminal, the ground mark can be easily recognized even in a place where the wiring is crowded in the same manner as described above. Also useful for maintenance.
