Abstract

PURPOSE:To enable a cover to be opened so as to expose required parts inside a case by a method wherein the cover is mounted on the case in a vertically slidable manner and fixed at a prescribed sliding position. CONSTITUTION:A cover 16 is provided covering the front side of a case 11 to protect a printed board 14 and a wiring connection terminal 15 located at the front of the case 11. The cover 16 is lifted upward sliding on slide ribs 12 at both the ends of the case 11, whereby the front side of the case 11 is gradually opened, and a protrudent engaging part 13 and a protrudent engaged part 18 are engaged with each other to fix the cover 16 at a prescribed sliding position, and the front side of the case 11 is partially exposed. That is, the prescribed position of the engaged part 18 formed on a slide groove 17 of the cover 16 is so set as to enable the fixing of the cover 16 by the engagement of the engaged part 18 with the engaging part 13 of the case 11 to be done at a point where a wiring connection terminal 15 located at the front of the case 11 is exposed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a cover device that is attached to the front side of a case that houses and holds electronic components, such as a housing of a main unit of a telephone, and covers electronic components, and particularly relates to a cover device that covers electronic components. Electronic component settings/
The present invention relates to a cover device that can be easily adjusted.

BACKGROUND ART FIGS. 2 and 3 show the structure of such a conventional cover device. In the figure, 1 is a box-shaped case with an opening 4 on the front that houses and holds a printed circuit board 2 on the upper side and wiring connection terminals 3 on the lower side, and 5 is a cover that covers and closes the front opening 4 of the case 1. It is rotatably attached to one side via a hinge member 6. 7 is a set screw for fixing the cover 5 to the case 1;
is inserted and fastened to case 1. Therefore, when setting or adjusting the wiring or the board, the setting screw 7 is removed and the cover 5 is opened.

Problems to be Solved by the Invention However, in the conventional cover device described above, the entire cover is attached to one side of the case via a hinge member, so when the cover is rotated, the front of the case is not fully opened. There is a problem that all the circuit boards inside the case are exposed. In other words, with such a device, even when adjusting the settings on the wiring, the cover is fully opened, so there is a risk of damaging the board.

SUMMARY OF THE INVENTION The present invention is intended to solve these conventional problems, and it is an object of the present invention to provide an excellent cover device in which the cover can be opened and closed to expose a desired portion inside the case.

Means for Solving the Problems In order to achieve the above object, the present invention is provided with slide ribs having locking portions in the vertical direction on both sides of the case,
The cover is provided with slide grooves on both sides that have locked portions that are slidably fitted into slide ribs of the case and that are locked to locking portions of the case at predetermined sliding positions of the cover, It is attached to the front side of the case.

Therefore, according to the present invention, in the normal state, the slide grooves on both sides of the cover fit into the slide ribs on both sides of the case to cover the front side of the case, and by sliding the cover upward, the front side of the case is covered. While gradually opening the side, the cover is fixed at a predetermined sliding position by engagement between the locking part of the case and the locked part of the cover, partially exposing the electronic components inside the case.

Example FIG. 1 shows the configuration of an embodiment of the present invention.

In the figure, 11 is a case made by bending a flat plate into an almost L-shape! , both side portions form slide ribs 12.

Reference numeral 13 denotes a protruding locking portion that is formed approximately in the middle of both slide ribs 1 and 2. A printed circuit board 14 is attached to the upper side of the front surface of the case 11, and wiring connection terminals 15 are attached to the lower side. 16 is a cover that surrounds the front side of the case 11, that is, the front part of the board 14 and the wiring connection terminal 15 on the front side of the case 11, and both sides of the upper part 7, and can slide on both side slide ribs 12 of the case 11 on both sides. A slide groove 17 is formed which fits into the slide groove 17.

Furthermore, a protruding locked portion 18 that is fitted and locked to the locking portion 13 of the case 11 is formed at a predetermined position in the slide groove 17 . Then, the cover 16 is assembled to the case 11 by fitting the slide ribs 12 into the slide grooves 17 on both sides and covering the case 11 from above.

Next, the operation of the above embodiment will be explained.

Under normal conditions, the cover 16 is placed over the front side of the case 11 to protect the printed circuit board 14 and the wiring connection terminals 15 on the front side of the case 11. Then, by lifting the cover 16 upward and sliding it on the slide ribs 12 on both sides of the case 11, the front side of the case 11 is gradually opened. By engaging with the locking portion 18, the cover 16 is fixed at a predetermined sliding position and the front side of the case 11 is partially exposed. In other words, the predetermined position of the locked portion 18 formed in the slide groove 17 of the cover 16 is the same as that of the locked portion 1 of the case 11.
．． The cover 16 is fixed by engagement with the case 11 at a portion where the wiring connection terminal 15 is exposed on the front surface of the case 11. Therefore, the cover 16 can be fixedly held with respect to the case 11 in a sliding position that exposes only the portion of the wiring connection terminal 15 on the front surface of the case 11.

In this way, according to the above embodiment, since the cover 16 is fixed at a place where the wiring connection terminal 15 is exposed, the entire front surface of the case 11 is not exposed when adjusting the settings on the wiring. The printed circuit board 14 on the front side of the printed circuit board 11 can be protected with a cover 16.

Effects of the Invention As is clear from the above embodiments, the present invention is such that the cover is attached to the case so as to be slidable in the vertical direction and is fixed at a predetermined sliding position. On the other hand, it can be opened and closed to partially expose internal electronic components while protecting other electronic components. For example, in the case of a main unit of a telephone, setting adjustments on the wiring can be made only at the wiring connection terminals. This can be done with only the printed circuit board exposed, thereby preventing damage to the printed circuit board during the work.
