Description

Header connector on hard disk drives

The present invention relates to a hard disk drive, and more particularly, to a header connector device installed in a base for connecting a head and a printed circuit board.

In general, a hard disk drive (HDD), which is an auxiliary memory device of a computer, is an electronic device and a mechanical device, and is a memory device that records / reproduces data by converting a digital electronic pulse into a more permanent magnetic field.

1 is a perspective view showing a configuration of a general hard disk drive, Figure 2 is an exploded perspective view showing a header connector device according to a conventional embodiment by expanding the dotted line of Figure 1, Figure 3 is a hard view according to the conventional embodiment A partial sectional view showing a header connector device of a disk drive.

As shown in FIG. 1, such a hard disk drive 100 includes a disk 50 for recording and storing data, recording data on the disk 50, or playing or recording recorded data. A magnetic head 44 to read, a spindle motor 52 for rotating the disk 50 at high speed, and the magnetic head 44 access data on the disk 50. Actuator (40: Actuator) to flow (Access), a printed circuit board assembly (PCBA) for controlling them, and an interface (Interface) for connecting the drive to the computer main body do.

In addition, a pivot axis (comprising a pivot screw and a pivot bearing), which is a rotational center of the actuator 40, is installed at one side of the center of the actuator 40. One side of the actuator 40 is wound a plurality of times and a voice coil 62 for moving the actuator 40 to a parking zone 54 and a data zone 56 is made of plastic. The bobbin 60 is installed on the bobbin, and the iron piece 64 is installed at the end of the bobbin 60.

Referring to the operating state of the hard disk drive configured as described above, when the power of the drive is "on", the spindle motor 52 is rotated at a constant circumferential speed, and thus the disk 50 fixed to the spindle motor 52 Also rotates at a constant speed. Subsequently, when the disk 50 rotates at a high speed, the magnetic head 44 floats to a constant height due to the pressure of the air film generated on the surface of the disk 50. The magnetic head 44 then moves to a track position on disk 50, and the drive sends a signal to the host computer that the drive is ready to perform a command via the interface.

When read / write information is input while the drive is ready for operation, the actuator 40 is rotated about the pivot axis 48 in accordance with the position and speed signals of the control circuit part, and the tip of the actuator 40 is rotated. The read / write head 44 fixed at the above moves to a desired position (constant track) on the disc 50. Thereafter, the magnetic head 44 is subjected to a read / write operation by the read / write circuit portion. At this time, the position and speed of the magnetic head 44 are controlled by the control circuit section even during the read / write operation.

In the hard disk drive operating as described above, in order to record information on a disk whose head is a storage medium or to read recorded information, a printed circuit board assembly (PCBA) and a head, which are circuit parts for signal processing, are electrically connected. Should be connected. In general, a header connector has been used for the connection of the head and the printed circuit board.

As shown in FIGS. 1 and 2, the header connector 10 includes a connector housing 20 having a plurality of pinholes, and a plurality of connector pins 30 inserted into holes formed in the connector housing. The header connector 10 is mounted to the base 70 that forms the connector seating groove 72.

In addition, a printed circuit board (not shown) is positioned on a lower side of the base 70, and the header connector 10 and the printed circuit board are connected through a connector socket 31. In addition, a flexible printed circuit 35 is installed between the header connector and the head to connect the header connector 10 and the head 44 to each other.

2 and 3, the header connector 10 is installed in the connector seating groove 72 formed in the base 70.

Referring to the process for attaching the header connector 10 to the base 70, the connector seating groove 72 of the base 70 is formed in the upper portion is large width and the lower portion is small width, the header connector ( 10, the upper portion is wider and the lower portion is formed smaller in width, the upper lower end of the header connector 10 is seated on the lower upper end of the connector seating groove (72).

At this time, a gap marked A occurs between the header connector 10 and the connector seating groove 72 of the base, and the header connector 10 is fixed to the base 70 by applying an adhesive between the gaps. Inserting the header connector fixed to the base in the oven as described above and heat treatment (Curing) to complete the mounting process of the header connector.

When using the above method, it takes a lot of time in the bonding process and the heat treatment process used to fix the header connector to the base, and the internal temperature rise during the hard disk drive operation generates gas from the adhesive to contaminate the environment. There was a problem.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a header connector device of a hard disk drive capable of shortening the manufacturing time of a header connector and fixing the header connector to a base without using an adhesive.

In order to achieve the above object, the present invention provides a hard disk drive, wherein the header connector device includes a connector housing having an upper catching portion extending in a horizontal direction from an upper portion and a lower catching portion extending in a horizontal direction from a lower portion thereof;

A header connector comprising a plurality of connector pins inserted into a plurality of pinholes formed in the connector housing, and a seating protrusion protruding to an inner center of a connector seating groove formed therein so as to seat an upper locking portion and a lower locking portion of the connector housing. It characterized in that the base is configured to secure a space in which the header connector can be inserted.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention relates to a hard disk drive, and more particularly, to a header connector device installed in a base for connecting a head and a printed circuit board.
