JPH0521393U - Fixed disk structure - Google Patents

Abstract

(57) [Summary] (Correction) [Purpose] The process of temporarily tightening the screws after temporarily fixing them when fixing the hard disk to the housing on the mounting side by providing the protrusions or recesses for mounting positioning. Has been removed to reduce the installation time compared to the conventional model. [Structure] First, the front panel 12a is attached to the mounting side housing 2a.
Secure with tapping screw 3. Next, the hard disk 1a is inserted from the rear into the hole of the front panel 12a and then moved to the rear, and the mounting positioning convex portion 11a provided on the hard disk 1a is attached to the convex portion receiving portion 2 of the mounting side housing 2a.
The mounting position is determined by inserting the disk into the hard disk 1a, the gap between the hole of the front panel 12a and the hard disk 1a becomes uniform, and the hard disk 1a is fixed with the screws 4 and 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a fixed disk, and more particularly to the structure of a fixed disk (hereinafter referred to as hard disk) of an auxiliary storage device used in an electronic computer or the like.

[0002]

[Prior Art]

 Conventionally, the structure of this type of hard disk has a structure in which a mounting screw hole is formed on the side surface for mounting on the mounting side housing.

[0003]

[Problems to be solved by the device]

 The structure of this conventional hard disk has a mounting screw hole on the side for mounting on the mounting side housing, so when fixing it to the mounting side housing with screws, In order to make the gap between the holes and the hard disk uniform, the screws must be temporarily tightened and then fully tightened, which has the drawback of requiring a long time for installation.

[0004]

[Means for Solving the Problems]

 The structure of the hard disk of the first invention has at least one positioning projection for mounting and positioning.

The hard disk structure of the second invention has at least one positioning recess for mounting and positioning.

[0006]

【Example】

 Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the first invention, (a) is a perspective view of this embodiment, (b) is a sectional view taken along the line AA of FIG. 1 (a), and FIG. FIG. 3 is a diagram showing a case where the present embodiment shown in FIG. 1 is mounted on a mounting side housing.

In FIG. 1, the hard disk 1a of this embodiment has a structure having a mounting positioning protrusion 11a on the back surface side.

Next, a method for mounting the hard disk of this embodiment on the mounting side housing will be described with reference to FIGS. 1 and 2.

First, the front panel 12 a is fixed to the mounting side housing 2 a with the tapping screw 3. Next, the hard disk 1a is inserted from the rear into the hole of the front panel 12a and then moved backward to insert the mounting positioning projection 11a provided on the hard disk 1a into the projection receiving portion 21a of the mounting side housing 2a. By doing so, the mounting position is determined, the clearance between the hole of the front panel 12a and the hard disk 1a becomes uniform, and the hard disk 1a is fixed with the screws 4 and 5.

FIG. 3 shows an embodiment of the second invention, (a) is a perspective view of this embodiment, (b) is a sectional view taken along the line AA of FIG. 3 (a), and FIG. FIG. 6 is a diagram showing a case where the present embodiment shown in FIG. 3 is mounted on a mounting side housing.

In FIG. 3, the hard disk 1b of the present embodiment has a structure having a mounting positioning recess 11b on the back surface side.

The method of attaching the hard disk 1b of the present embodiment to the attachment side housing 2b is the same as that of the hard disk 1a of the first embodiment of the present invention shown in FIG.

[0014]

[Effect of the device]

 As described above, the present invention eliminates the step of temporarily tightening the screws and then fully tightening them when fixing the hard disk to the housing on the mounting side by providing the protrusions or recesses for mounting and positioning. Therefore, there is an effect that the installation time can be shortened as compared with the conventional case.
