Abstract

PURPOSE:To improve an workability by attaching a connector connected during assembling hermetic seal housing to the stator of a motor and the hermetic seal respectively. CONSTITUTION:Electric wires to be led out from a stator 9 are aggregated to a connector 13 fixed to the stator 9 and a connector 12 belonging to a hermetic seal 11 is disposed and fixed at a position to be connected to the connector 13. Accordingly, when the hermetic seal 11 is fixed to a base plate 1, the connector 12 is connected to the connector 13. Thereby, when incorporating a motor in a housing, an assembling can be executed without contacting the electric wire with a rotor 10 and an workability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic disk device, and particularly to a magnetic disk device having a unique drive motor connection structure.

[Prior Art] In general, as the performance of magnetic disk devices increases, the flying height of the magnetic head decreases, and it is necessary to prevent dust from entering the device. Therefore, hermetic seals and the like are used as sealing technology for housing joints. The number of structures that are used to seal the air is increasing. In this type of magnetic disk device, a cable is soldered to a hermetic seal and connected to a hermetic seal to supply power to the motor in the housing, thereby driving and rotating the motor. Here, the term "housing" refers to a composite body such as a base plate, a cover, etc. that accommodates a spindle section, a magnetic head drive section, and the like.

[Problems to be solved] In the conventional sealed magnetic disk drive described above, the drive motor and the hermetic seal are connected by soldering cables, so when the motor is assembled into the housing, it is difficult to connect the motor and the hermetic seal. The connection cable may come into contact with the motor's rotating part (rotor) or may enter between the hermetic seal and the housing. If the connection cable is assembled in this state, the connection cable may become disconnected and the motor will not drive. Furthermore, a device in which the motor and hermetic seal are connected by a cable has the disadvantage that soldering requires careful handling of the parts, resulting in very poor workability.

[Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned conventional problems, such as when the connecting cable comes into contact with the rotating part of the motor when the motor is assembled into the housing, and the contact seal and housing It is an object of the present invention to provide a magnetic disk device which does not cause a failure due to wire breakage due to interference, and which is easy to work with.

To this end, the present invention provides a housing that hermetically houses a plurality of magnetic disks and a motor that rotates the magnetic disks, and a hermetic seal that is disposed in a part of the housing and to which electric wires of the motor are connected. A magnetic disk drive comprising: a stator of the motor and a hermetic seal, each of which is provided with a connector that is joined when the hermetic seal is assembled to the housing. It is something to do.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a magnetic disk device according to an embodiment of the present invention. The housing consists of base plate l and cover 2
A head drive section 5 and a spindle section 7 are fixed to the base plate l while being enclosed therein. A plurality of magnetic disks 3 are stacked on the spindle section 7, and a magnetic heald 4 is positioned facing the magnetic disks 3 and mounted on a head drive section 5. Further, in the spindle portion 7, a spindle shaft 6 is supported on the base plate 1 via a bearing 8, and transmits the rotational motion of a motor consisting of a rotor 10 and a stator 9.

The electric wires to be output from the stator 9 are collected in a connector 13 fixed to the stator 9, while the connector 12 attached to the hermetic seal 11 is arranged and fixed at a position where it is to be joined to the connector 13. As a result, when fixing the hermetic seal 11 to the base plate 1, the connector 12 is joined to the connector 13.

Therefore, when assembling the motor into the housing, the assembly can be performed without the electric wires coming into contact with the rotor 10, and work efficiency is improved.

[Effects of the Invention] As explained above, the present invention provides a housing that seals and accommodates a plurality of magnetic disks and a motor that rotates the magnetic disks, and a housing that is disposed in a part of the housing,
In the magnetic disk drive including a hermetic seal to which electric wires of the motor are connected, each of the stator of the motor and the hermetic seal is provided with a connector that is joined when the hermetic seal is assembled to the housing. Since the magnetic disk device is characterized by The effect is that the assembly work of the seal can be completed.
