のことである。DISCLOSURE OF THE INVENTION (Embodiment) As shown in FIG. 2, a housing of a body is formed by combining a body 1 and a cover 2. The body 1 is formed in a box shape having an open top surface, and the cover 2 is formed in a box shape having an open bottom surface, so that the cover 2 is fitted onto the body 1 so that their opening surfaces coincide with each other. Has become.
As shown in FIGS. 1 to 3, the notch 3 on the abutting surface of the body 1 faces the abutting surface and penetrates the front and back of the peripheral wall.
And a mounting groove 4 is formed on the inner peripheral surface of the notch 3. The mounting groove 4 is provided from both side surfaces to the bottom surface of the notch 3, and is composed of a vertical mounting groove 4a on both side surfaces and a horizontal mounting groove 4b on the bottom surface. A holding plate 5 is detachably inserted into the mounting groove 4. The holding plate 5 is formed in a rectangular shape, and insertion notches 6a and 6b are formed on a pair of long sides facing each other. Both insertion notches 6a, 6b are formed to have different widths. For example, as shown in FIG. 4, one insertion notch 6a is set to have a width W 1 corresponding to three electric wires 7, and the other The notch 6b for insertion is set to a width W 2 corresponding to the two electric wires 7. Where notch for insertion
Although 6a and 6b are formed to correspond to the two electric wires 7 and the three electric wires 7, it goes without saying that other numbers may be set.
以上の構成により、保持板５を取付溝４内に装着する

り取って保持板５を装着するようにしてもよい。With the above configuration, by mounting the holding plate 5 in the mounting groove 4, a hole for inserting the electric wire 7 is formed between the body 1 and the cover 2. It is possible to handle a plurality of types of electric wires 7. When the cutouts 6a, 6b for insertion are set to the width as described above, if the cutout 3 is set to the width corresponding to the four electric wires 7, the holding plate 5 is put in the cutout 3. With the holding plate 5 removed, three types of states can be set. Further, one of the insertion notches 6a and 6b of the holding plate 5 is made to face the notch 3 to form a wire drawing hole corresponding to the width of the electric wire 7, but the other notch not made to face the notch 3 6a
Alternatively, 6b faces the mounting groove 4, and no extra opening is formed by the other insertion notch 6a or 6b. In the above example, the holding plate 5 is formed in a rectangular shape, and the notches 6a and 6b for insertion are formed only on two sides of the rectangular shape. However, the holding plate 5 is formed in a square shape and each side has a different width. By forming a general cutout, it is possible to correspond to four types of electric wires 7. Further, if the insertion notch is not formed on one side of the holding plate 5, the notch 3 can be closed when it is not necessary to draw out the electric wire 7. Further, a rib that fits into the mounting groove 4 and is capable of being broken is provided at the lower edge of the cover 2 so that the notch 3 is closed by the rib when the product is shipped, and the rib is broken as necessary. Alternatively, the holding plate 5 may be attached.
以上の実施例では、ボディ１に切欠３を形成している
が、カバー２に切欠３を形成しても同様の効果を奏する
ことができる。Although the notch 3 is formed in the body 1 in the above embodiments, the same effect can be obtained even if the notch 3 is formed in the cover 2.

In a body of an electric device that has a notch penetrating the front and back of the peripheral wall of the housing and facing the abutting surface of the cover, a mounting groove is formed from both sides of the inner circumference of the notch to the bottom surface, Since the holding plate having at least one insertion notch facing the mounting groove is detachably inserted into the above-mentioned mounting groove so as to close the notch, the notch for insertion is not required to be processed later. Attach the holding plate to the mounting groove while facing the inside to form a wire drawing hole, or attach the holding plate to the mounting groove with the insertion notch facing the mounting groove. As a result, the insertion notch can be closed by the mounting groove, and the holding plate can close the notch.
Furthermore, since post-processing such as cutting is not required, it is possible to finish the product with an excellent appearance as a molded product, and it is also possible to prevent foreign matter from entering inside during post-processing.
