As shown in FIG. 1, the present invention has a display card fixing structure for fixing a display card 4 having a name or the like to an electronic device housing 3 such as an interphone slave unit, in which electronic components (not shown) are accommodated. To cover the inner case 2, a resin cover 1 is combined to constitute an electronic device casing 3.
[0012]
In order to fix the display card 4 to the electronic device casing 3, the cover 1 is provided with a window 10 into which the display card 4 is inserted and held. The window 10 has a pair of holding portions 10a and 10a either vertically or horizontally.
[0013]
As shown in FIG. 2 (b), if the width of the window 10 is slightly smaller than the width N of the display card 4 so that the window 10 is smaller than the display card 4 in the holding part 10 a, the window 10 The display card 4 is pressed from the front side by the pair of holding portions 10a and 10a. It is more preferable that the holding portion 10a covering the display card 4 with the back surface 10b of the window is made thin and the corresponding surface 4a of the display card 4 is also made thin to prevent the movement of the display card 4 in the window 10.
[0014]
On the outer periphery 11 of the window 10, at least one pair of elastic claws 12, 12 extend in the direction of the back surface 10 b of the window 10 at a position substantially orthogonal to the pair of holding portions 10 a, 10 a.
[0015]
In FIG. 1, two pairs of elastic claws 12, 12 are shown. Further, in FIG. 1, the elastic claw portion 12 is provided up and down, and the holding portions 10a substantially orthogonal to the left and right are provided on the left and right.
[0016]
As shown in FIGS. 2 (c) to 2 (e), the elastic claw portion 12 includes a leg portion 13, inclined surfaces 12 a and 12 c projecting on the distal end side, and an end surface 12 b connecting both.
[0017]
As shown in FIG. 2 (e), the distance X between the end face 12b and the end face 12b of the elastic claw part 12 is configured to be slightly shorter than the height Y of the display card 4 fitted therein, and the elasticity of the elastic claw part 12 When the display card 4 is fitted against this, the back surface 10b side is caught by the end portion 12b of the elastic claw portion 12, and the front surface side of the cover 1 is locked by the pair of holding portions 10a, 10a of the window 10. The display card 4 is temporarily fixed.
[0018]
In addition, since the cover 1 is resinous and the elastic claw portion 12 is made of this constituent member, after the display card 4 is inserted, the bending of the leg portion 13 is restored due to the resin elasticity.
[0019]
The inner case 2 to which the cover 1 is mated has a pressing surface 21 that fixes the display card 4 to the cover 1 in the mated state.
[0020]
Hereinafter, the operation of the display card fixing structure of the present invention will be described.
[0021]
As shown in FIG. 2 (c), when the display card 4 is fitted in the arrow direction (A) against the elasticity of the elastic claw portion 12 from the inner case 2 side, the leg portion of the elastic claw portion 12 13 is bent, the end portion 41 of the display card 4 slides on the inclined surface 12a of the elastic claw portion 12, and gets over the inclination of the end surface 12b of the elastic claw portion 12. Since the end 41 of the display card 4 over the end surface 12b hits the inclined surface 12c of the elastic claw portion 12, it is caught by the end surface 12b and held by the cover 1, and the front side of the cover 1 is a pair of holding portions 10a of the window 10. 10a and temporarily fixed.
[0022]
Next, when the cover 1 and the inner case 2 are fitted and fixed together using the screw B, the display card 4 is placed between the pressing surface 21 of the inner case 2 and the cover 1, that is, the electronic device casing 3. Fixed.
[0023]
As shown in FIG. 2 (d), when the display card 4 is pulled out in the direction of the arrow (B), the end portion 42 of the display card 4 is inclined to the inclined surface of the elastic claw portion 12 when the 12 leg portions 13 are bent. The display card 4 can be removed from the housing 3 by sliding 12c and getting over the end face 12b.
[0024]
According to the display card fixing structure of the present invention, since the display card 4 is sandwiched between the window 10 and the elastic claw portion 12 of the cover 1, the display card 4 does not fall off even if there is no separate part, and from the surface of the housing 3. It will not be removed. Since the display card 4 can be temporarily fixed by the window 10 and the elastic claw portion 12 of the cover 1 and is detachable, as long as the cover 1 is removed from the inner case 2, the display card 4 can be replaced or the contents of entry can be changed smoothly. Is called.
