Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for screwing a tape deck or the like to a housing.

As shown in Figure 1, there is a deck 2 on the bottom surface 10 of the housing.
0, screw the screw 30 from the outside of the bottom surface 10 of the casing into the mounting foot 21 that has a screw hole provided on the bottom surface of the deck 20, and screw the screw 30 into the bottom surface of the casing so that the head does not protrude to the outside. 10 may be provided with an inwardly directed aperture 11. The top of this diaphragm 11 is flat, and there is a hole in the center for passing the screw 30 through, but the peripheral part has a relatively steeply descending slope, so that the mounting foot 21 does not fit well on the top of the diaphragm 11 during installation. Otherwise, it will slide down as shown by the broken line. The aperture 11 is 3 depending on the mounting foot 21.
Since more than one aperture is formed, it becomes extremely difficult to screw the mounting feet 21 onto all of the apertures 11.

The present invention aims to prevent the mounting foot from slipping off by forming a recess in the above-mentioned aperture, thereby facilitating the mounting of a deck or the like.

The present invention provides an installation structure for a deck, etc., in which a deck, etc. is housed inside the housing, and a plurality of mounting feet, which are set up on the bottom surface of the deck, are screwed to the bottom surface of the housing. A constricted portion protruding toward the inside of the casing is provided at a position corresponding to the foot, and a concave portion having a partially flat portion in which a hole for attaching a screw is formed at the top of the constricted portion surrounds the mounting foot. This feature is characterized in that the mounting foot is placed in the recessed portion, and this will be explained in detail below with reference to the illustrated embodiment.

FIG. 2 is a sectional view of a main part showing an embodiment of the present invention, in which 12 is a flat part where the top of the aperture 11 is recessed;
13 is a screw through hole in the center, 14 is a peripheral part of the top protruding toward the inside of the housing, 22 is a screw hole for the mounting foot 21, 40 is a printed circuit board, and 41 is a mounting foot formed in a part thereof. This is the guide hole. The flat portion 12 of the diaphragm 11 is set between the peripheral portion 14 and the bottom surface 10, and not only prevents the head of the screw 30 from protruding outside the housing, but also forms a recessed portion for receiving the mounting foot 21. Therefore, when the deck 20 is attached (before screwing), the attachment foot 21 is reliably prevented from slipping off the aperture 11. Moreover, since the guide hole 41 is provided in the printed circuit board 40,
It is easy to guide the mounting foot 21 onto the aperture 11.

FIG. 3 is an explanatory diagram of this, in which the mounting foot 21 slides onto the diaphragm 11 in the order of (1)→(3). At this time, if the center part of the aperture 11 is made into a dome shape as shown in (2), the mounting foot 21 will be guided to the hole 13 position by the slope 15, and the subsequent positioning when tightening the screws will be facilitated. Become. The hole 41 of the printed circuit board 40 is usually formed to have a large diameter in order to avoid a screw portion, and does not have a guiding function for the mounting foot 21. For this reason, the mounting foot 21
If a separate guide mechanism is provided, the cost will increase, but if the hole 41 of the printed circuit board 40 is used for that purpose as in this example, the cost can be reduced.

FIG. 4 is an overall view, and the printed circuit board 40 is provided with three guide holes 41. This is made to match the number of mounting legs 21 and, therefore, the number of apertures 11. 43 is an electronic component mounted on the printed circuit board 40, and 1 is a housing. In this example, if the deck 20 is placed on the printed circuit board 40 and moved back and forth and left and right, the mounting feet 21 will eventually be attached to the printed circuit board 40.
into the guide hole 41 and temporarily fixed to the center of the diaphragm 11. When the screws 30 are screwed together in this state, the deck 20 is permanently fixed to the bottom surface 10 of the casing. Although the printed circuit board 40 is fixed to the housing 1,
The mechanism has been omitted.

As described above, according to the present invention, since the screw head does not protrude outside the housing, there is an advantage that the work of screwing a deck or the like onto the aperture on the bottom of the housing becomes extremely easy.
