Abstract

(57) [Abstract] [Purpose] To provide a disk drive device that can be made compact by eliminating the need for a long flexible flat cable for connecting a tray on which a disk is mounted and taken in and out of a main body cover to the outside. The purpose is to do. A pattern 30 is formed on the bottom of the main body cover 21, and the lower end of the flexible terminal 29 on the external interface connector 27 side is grounded at the end of the pattern 30. Also, the spring terminal 4 is provided on the tray side where the disc is mounted.
1 is provided, and the bent portion 41c is grounded to the pattern 30. When the tray is taken in and out of the main body cover 21, the bent portion 41c is always in contact with the pattern 30. Since the flexible flat cable conventionally required for connecting the external interface connector 27 and the tray can be removed, a storage space for the flexible flat cable can be eliminated, so that the tray can be downsized in the sliding direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk drive device having a simplified structure of an interface portion for connection with the outside.

[0002]

2. Description of the Related Art In recent years, disk drive devices have become widespread in the fields of audiovisual equipment, information communication equipment and the like. Further, due to the downsizing of equipment accompanying the widespread business activities, further downsizing of the disk drive device is required. However, a flexible flat cable and a connector are used for the interface portion of the disk drive device, which hinders the downsizing of the device.

A conventional disk drive device will be described below. FIG. 3 is a perspective view of a conventional disk drive device. In FIG. 3, 1 is a main body cover, 2 is a tray, 3 is an eject switch for ejecting the tray 2, 4 is a guide rail for moving the tray 2 back and forth, 5 is a disk, 6 is a main board, 7 is an external interface connector, 8 Is an internal interface connector provided on the upper surface of the main board 6, and 9 is a flexible flat cable for connecting the external interface connector 7 and the internal interface connector 8. The tray 2 on which the disk 5 is mounted is slid in the main body cover 1 in the direction of the arrow to be taken in and out of the main body cover 1. It has a long length.

FIG. 4 is a diagram for explaining the operation of a conventional disk drive device. The operation of the disk drive device configured as described above will be described below. First, as shown in FIG. 4A, the tray 2, the disk 5, and the substrate 6 are contained in the main body cover 1 while the disk drive is operating. In this state, the flexible flat cable 9 is bent between the external interface connector 7 and the internal interface connector 8 to be housed. Further, when the disc 5 is taken out, the eject switch 3 is operated so that the disc shown in FIG.
As shown in (b), the tray 2 is taken out from the main body cover 1. In this state, the flexible flat cable 9
Is stretched long.

[0005]

However, in the above-mentioned conventional configuration, a space for bending and accommodating the long flexible flat cable 9 is required between the external interface connector 7 and the internal interface connector 8 during operation of the disk drive device. This is an obstacle to the miniaturization of the disk drive device.

It is therefore an object of the present invention to provide a disk drive device which can be downsized by eliminating the conventional connecting method using a flexible flat cable and an interface connector.

[0007]

To this end, according to the present invention, a pattern is formed on the bottom of a main body cover to be connected to an external interface connector, and a spring terminal that is elastically grounded and slides on the pattern on the tray side. Is provided. Further, a dustproof sheet that is grounded to the pattern is provided on the tray side.

[0008]

According to the above construction, when the tray is slid with respect to the main body cover, the spring terminals are always grounded in the pattern and slid. By forming a pattern instead of a long flexible flat cable, there is no need for a space to store the flexible flat cable.
The disk drive device can be miniaturized. Further, the dustproof sheet can prevent dust from entering the electrical contact portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a disk drive device according to an embodiment of the present invention, and FIG. 2 is a sectional view of the same. In FIG. 1, 21 is a main body cover, 22 is a tray, and 23 is a tray 2.
Eject switch, 24 is tray 2
Guide rails for moving back and forth, 25 for disks, 26 for main board, 27 for external interface connector, 2
Reference numeral 8 is a spring-type connector provided on the lower surface of the main board 26, 30 is a pattern bonded to the bottom of the main body cover 21, 29 is a flexible terminal for connecting the external interface connector 27 and the pattern 30, and the lower end portion thereof. Are elastically grounded to the pattern 30. The tray 22 on which the disc 25 is mounted slides in and out of the main body cover 21 in the direction of the arrow.

FIG. 2 is a view showing the structure of the spring type connector 28, and the right half part of FIG. 2 is a side view of the left half part. In FIG. 2, 40 is a case of the spring type connector 28, 41 is a spring terminal, 42 is a pin for positioning the spring terminal 41, 44 is a screw for fixing the case 40 to the main board 26, 45 is a dustproof sheet, and 46 is a dustproof sheet. It is a pattern.

As shown in FIG. 2, one end 4 of the spring terminal 41 is
1a is mounted on a pattern 46 formed on the lower surface of the main substrate 26, and the other end 41b has a degree of freedom in the vertical direction due to the elasticity of a spring. Further, as shown in FIG. 1, the external interface connector 27 is connected to a pattern 30 adhered to the bottom portion of the main body cover 21 via a flexible terminal 29. The bent portion 41c formed at the center of the spring terminal 41 is positioned so as to slide on the pattern 30 while always being grounded to the pattern 30. Further, in order to prevent dust from entering the contact portion with the pattern 30, a dustproof sheet 45 having elasticity is attached to the side surface of the case 40.

Therefore, in FIG. 1 and FIG. 2, when the tray 22 is slid in the direction of the arrow and put in and out of the main body cover 21, the bent portion 41c of the spring terminal 41 is always in contact with the pattern 30 and the above-mentioned conventional method is used. Since the long flexible flat cable 9 can be eliminated, the tray 22 can be sufficiently close to the direction of the external interface connector 27 as shown in FIG. 2, and the tray of the disk drive device can be made smaller in the sliding direction. realizable.

[0013]

As described above, according to the present invention, a pattern to be connected to an external interface connector is formed on the bottom of the main body cover, and a spring terminal is provided on the tray side for elastically grounding and sliding on this pattern. Since the long flexible flat cable, which was required in the past, can be removed and the storage space for it can be eliminated, the slide direction of the disc drive device tray can be made smaller and a compact disc drive device can be realized. it can. Further, the dustproof sheet can prevent dust from entering the electrical contact portion.
