2. Description of the Related Art Conventionally, a hard disk drive (HDD) used for electronic equipment such as a computer has been configured to be hot-swappable.

Conventionally, for example, a plurality of HDDs can be connected to an electronic device such as a computer, and while some of the HDDs are used while the power of the electronic device body is turned on, other HDDs are used.
D is removed as necessary for replacement or the like, and a new HDD is connected to the electronic device. As a method of attaching and detaching the HDD without turning off the power, there is a method called hot-line insertion / removal in which a box-type HDD storage chassis having an opening on one surface is used, and the HDD is inserted into and removed from the storage chassis through the opening. In this method, a connector on the HDD side is inserted into a connector provided on the back side of the storage chassis, and the electronic device body and the HDD are electrically connected, and the HDD is rigidly fixed to the storage chassis. Such a method by insertion / removal is easy and convenient because the attaching / detaching operation is simple. In this method, a dimensional clearance is provided between the storage chassis and the HDD to enable smooth insertion and removal.

[0004]

The HDD has a movable portion such as a rotating magnetic disk inside, and can generate vibration by its operation. Therefore, if there is a dimensional clearance between the storage chassis and the HDD as described above, there is a problem that the HDD itself vibrates in that range, which may lead to an error in HDD operation. In particular, in the read / write operation of the HDD, the arm is positioned with a precision of about 1 μm on a magnetic disk as an internal data recording medium, and an error occurs even with a small amplitude of about the dimensional clearance of the storage chassis. There is a risk.

[0005] Further, even if the HDD is fixed via a connector at the back of the storage chassis, it is movable on the front side within the above-mentioned dimensional clearance. Therefore, due to the rotation of the disk in the HDD, swinging in the direction along the disk surface with the connector portion fixing the HDD at the back of the storage chassis as a fulcrum tends to occur, and the swinging in this direction is caused by the arm of the HDD. However, there is a problem that the positioning accuracy is easily affected.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to suppress vibration of an insertion / extraction device or an insertion / extraction module inserted into or removed from an electronic device, such as an HDD, in a storage section.

Further, another insertion / extraction device according to the present invention has a unit holder for holding the plug-in unit,
The unit holder includes the protrusion.

[0010] In the insertion / extraction device according to the present invention, the projection is projected toward at least one of the swing displacement directions that can occur around a connecting portion between the plug-in unit and the main body as a fulcrum. I do.

[First Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a storage chassis (storage portion) provided in an electronic apparatus according to a first embodiment of the present invention and an HDD module (insertion / extraction device or insertion / extraction module) inserted / extracted into / from it. In FIG. 1, a storage chassis 2 is formed in a “U” shape using a metal plate or the like, and a substrate 6 having a connector or the like to which the HDD module 4 is connected is mounted facing one opening thereof. Be placed. The storage chassis 2 and the substrate 6 are fixed with screws via a spacer 8. HDD module 4 is storage chassis 2
And the connector provided at the front end in the insertion direction and the connector of the board 6 are connected. The storage chassis 2 is arranged, for example, with its opening facing sideways, and a plurality of HDD modules 4 can be mounted on the storage chassis 2 in parallel, for example, in an upright state.

FIG. 2 is a schematic side view showing a state where the HDD module 4 is inserted into the storage chassis 2. H
The DD module 4 has a structure in which an HDD body 10 (plug-in unit) connected to an electronic device and functioning as a part thereof is held by a holder 12 (unit holder). The HDD main body 10 is fixed to the holder 12 by screws or the like, and the holder 12 is configured to have an outer shape corresponding to the storage chassis 2. By using the holder 12, it is possible to attach the HDD main body 10 to the storage chassis 2 even if there is a difference in the shape.

In the HDD module 4, the connector of the HDD body 10 is inserted into a connector 14 provided on the substrate 6. Thus, the HDD module 4 is fixed to the electronic device main body at the front end in the insertion direction.

On the other hand, the height of the HDD module 4 is configured to be slightly smaller than the opening height of the storage chassis 2 in consideration of the dimensional clearance. In FIG. 2, the dimensional clearance is represented as a gap 16 between the upper surface of the HDD module 4 and the inner surface of the storage chassis 2. In this way, by providing the dimensional clearance, even if the storage chassis 2 and the HDD module 4 have a slight variation in size, they can be smoothly attached and detached without interference between them.

Now, the magnetic disk is stored inside the HDD main body 10 so as to rotate in the vertical direction, and the HDD main body 10 and the HDD module 4 may fluctuate in the vertical direction accordingly. Therefore, the HDD module 4 tends to vibrate up and down in the storage chassis 2 with the connector 14 as a fulcrum.

The feature of this device is that a projection 20 is provided on the upper surface of the HDD module 4 in order to suppress this vibration. The protrusion 20 is provided on the holder 12 and has a height corresponding to the gap 16. The protrusion 20 is provided in the HDD module 4.
Is pressed into contact with the inner wall of the storage chassis 2 in a state of being inserted into the storage chassis 2. Thus, the HDD module 4 is not only fixed at the front end in the insertion direction, but also fixed to the electronic device main body in the vertical direction. This allows
Vertical vibration of the HDD module 4 due to the rotation of the magnetic disk described above is suppressed.

The projections 20 are pressed against the inner wall of the storage chassis 2 so that friction occurs during insertion and removal. However, since the contact area with the storage chassis 2 is small, the resistance is suppressed. Therefore, the worker can easily insert and remove the HDD module 4. Further, if the projection 20 is provided at a position closer to the user when viewed from the side where the HDD module 4 is inserted, the distance between the projection 20 and the inner wall of the storage chassis 2 is reduced, so that the HDD module 4 can be more easily inserted and removed. Is realized.

The position of the projection 20 in the insertion direction is determined from the viewpoint of effectively suppressing vibration. For example, it is considered that the effect of suppressing vibration is weakened at a position too close to the connector 14. So, for example,
It is preferable that the projection 20 be provided near the center of the HDD main body 10 or at a position on the insertion opening side of the storage chassis 2 therefrom. In the example shown in FIG. 2, the projection 20 is arranged near the insertion opening from such a viewpoint. More specifically, for example,
A suitable position can be determined based on the analysis of the vibration cycle and the natural vibration mode of the HDD module 4. Depending on the result, the protrusion 20 is not limited to one place in the insertion direction,
In some cases, it may be preferable to provide them at several places.

In the present embodiment, the projection 20 is
The storage chassis 2 is made of the same hard material as metal as
The distance of the gap 16 between the HDD module 4 and the HDD module 4 does not change, that is, the HDD module 4 does not vibrate. However, a material different from that of the holder 12 is used as long as the vibration can be suppressed against the force for moving the HDD module 4 up and down by the rotation of the magnetic disk and the moment at the position of the protrusion 20 caused by the force. Thus, the protrusion 20 can be made of a material having a certain degree of elasticity.

FIG. 2 shows an example in which the protrusion 20 is provided on one of the upper side and the lower side of the HDD module 4. On the other hand, the example shown in FIG. 3 has a configuration in which the protrusions 20 are provided on both surfaces of the HDD module 4 facing the inner wall of the storage chassis 2. As described above, the configuration in which the protrusions 20 are provided on both sides is as follows.
This is particularly suitable for an electronic device in which the HDD module 4 is horizontally disposed in the storage chassis 2 and the protrusions 20 are in contact with the left and right inner walls of the storage chassis 2.

The shape of the projection 20 is not limited to a hemispherical shape as shown in FIGS. FIG. 4 is a schematic sectional view showing the shape of another projection. FIG. 4A shows a protrusion 21 having a triangular cross section. FIG. 2B shows a projection 22 having a trapezoidal cross section, and has a flat portion on the top. FIG. 3C shows that the projection 21 having a triangular cross section is
This is a configuration provided in a row.

The above HDD module 4 is an HDD module.
Although the HDD 10 includes the main body 10 and the holder 12, the HDD main body 10 may be mounted on the storage chassis 2 without using the holder 12. In this case, the vibration of the HDD main body 10 can be similarly suppressed by providing the projection 20 on the surface of the HDD main body 10 facing the storage chassis 2.

[Second Embodiment] FIG. 5 is a perspective view of a storage chassis provided in an electronic apparatus according to a second embodiment of the present invention and an HDD module inserted into and removed from the storage chassis.
In FIG. 5, the same components as those in the above embodiment are denoted by the same reference numerals, and the description will be simplified. This embodiment is different from the above-described embodiment in that the HDD module 30
This is the point that a projection for suppressing the vibration of is provided on the storage chassis 32 side. The protrusion 34 is formed by, for example, stamping a metal plate constituting the storage chassis 32 inside the storage chassis 32, and appears as a concave portion formed outside the storage chassis 32 in FIG. 5.

FIG. 6 is a schematic side view showing a state where the HDD module 30 is inserted into the storage chassis 32. The protrusion 34 is, for example, triangular and is provided on the front side of the upper surface of the insertion opening of the storage chassis 32. A portion 36 of the upper surface of the holder 35 of the HDD module 30 that faces the projection 34 in the mounted state is configured to be pressed against the projection 34. On the other hand, a portion closer to the front in the insertion direction than the press contact portion 36 is formed by being receded from the top of the projection 34, and the loose insertion portion 3 that allows loose insertion into the storage chassis 32.
8 That is, the loose insertion portion 38 is formed so as to be one step lower than the front portion 36, and friction with the projection 34 is avoided or reduced, so that the HDD module 30 can be smoothly inserted into and extracted from the storage chassis 32.

FIG. 6 shows an example in which a projection 34 is provided on the upper inner wall of the storage chassis 32. On the other hand, the example shown in FIG. 7 has a configuration in which the protrusions 34 are provided on the inner walls on both sides of the storage chassis 32 that are in contact with the HDD module 4. In this case, both the left and right sides of the HDD module 30 (HD
The press-contact portion 36 and the loose insertion portion 38 are formed on the D module 4 when the D module 4 is stored horizontally or on both the upper and lower surfaces (when the HDD module 4 is stored vertically).

FIG. 8 is a perspective view of an example of the HDD module 30. The HDD module 30 is characterized in that the loose insertion portion 38 is formed as a groove 40 in the insertion / extraction direction. That is, the groove 40 is formed at a depth that avoids the protrusion 34. That is, the bottom of the groove 40 and the storage chassis 32
Is larger than the value required for the dimensional clearance, while the distance between both sides of the groove 40 and the storage chassis 32 and the distance between the press-contact portion 36 and the storage chassis 32 are formed to be approximately the dimensional clearance. By forming the loose insertion portion 38 as the groove 40 in this manner, smooth insertion and removal is realized in that friction is not received by the projection 34. In addition, since the projections 34 and the grooves 40 are engaged with each other, the grooves 4 are formed.
0 functions as a guide when the HDD module 30 is inserted and removed, and the HDD module 30 is inserted and removed without blurring.

By forming the boundary between the loose insertion portion 38 and the press-contact portion 36 on a gentle slope, the HDD
When the module 30 is inserted into the storage chassis 32, the protrusion 34 can pass through the boundary more smoothly.
