Description

Shunt connector jig of hard disk drive {SHUNT CONNECTOR JIG FOR HARD DISK DRIVE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grounding process of a hard disk drive used as an auxiliary memory device of a computer, and in particular, to prevent head damage occurring during assembly or movement by performing grounding, 16 pins (16 pins). The present invention relates to a shunt connector jig installed in the shunt connector jig.

In general, information storage devices include a floppy disk drive (FDD) or a hard disk drive (HDD), which are used as a secondary storage device of a computer, and a CD-ROM or optical media used for multimedia media such as audio and video. Optical disk drives, such as magnetic disk drives.

Among these disk drives, the hard disk drive, which is widely used as a computer auxiliary storage device, uses the principle of magnetic recording, and uses a disk coated with a head and a magnetic material as a medium for recording and reproducing data. .

In addition, such a conventional hard disk drive is a mechatronics product line consisting of electronic devices and mechanical devices, and assists in recording and reproducing information by sending a digital signal to a head having an electromagnet role and recording it on a disc having magnetization properties. It is a widely used device among storage devices. Conventional hard disk drive is a very precise device, a device that is very sensitive to external shock or vibration.

In today's multimedia environment, high capacity recording is inevitable due to high-density recording of hard disk drives. Therefore, the drive industry is competing for the development of new heads and media, as well as the development of new technologies and more innovative technologies. This is fierce.

Such a conventional hard disk drive is shown in FIG. 1 is a plan view illustrating a base assembly 10 of a hard disk drive according to a conventional embodiment. The drawing is a state in which the printed circuit board assembly (PCBA) is not assembled to the base assembly 10.

Although not shown in the drawing, a printed circuit board assembly is assembled upward based on the base 10, a spindle motor in the center in the bottom direction, an actuator beside the spindle motor, a disk in the bottom direction of the spindle motor, Next to the 16-pin connector 20, key components such as a voice coil motor are mounted.

In the figure, fastening holes 101, 102, 103, and 104 are formed at the four corners of the base 10, and are fastened to the cover not shown using four screws. The cover and the base 10 are coupled by equally acting the fastening force in the vertical direction by the screws on the four parts.

16 pin 20 (16 pin) connector is located at one corner of the base 10. The 16-pin connector is connected to the connector of the flexible printed circuit (FBC) not shown in the figure. At this time, the flexible printed circuit is connected to a head installed at the free end of the suspension of the actuator. Such a connection state is not shown in the drawings.

However, when assembling such a hard disk drive assembly (HDDA), electrostatic discharge (ESD) is affected by contact with the assembled hard disk drive assembly, which is included in an operator, equipment, and jigs. Therefore, damage to the head inside the hard disk drive assembly adversely affects the performance of the head, and causes head related defects in various processes after assembly.

In the currently used thin film heads, there is no problem because of the small head damage effect caused by ESD without any additional means.However, in the hard disk drive using MR head, ESD is much weaker than thin film head. Needed the means of This problem was solved by using the connector socket after the grounding process, but a lot of labor and quantity is required, and workability is deteriorated again.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a base assembly of a hard disk drive using a shunt connector jig.

Another object of the present invention is to provide a base assembly of a hard disk drive, which prevents head damage by preventing static electricity from flowing directly to the head by grounding in a hard disk drive using an MR head.

It is still another object of the present invention to provide a shunt connector jig for a hard disk drive which is simple in operation.

In order to achieve the above objects, the present invention, in the base assembly of the hard disk drive of the state before assembling the printed circuit board assembly during the hard disk drive assembly process,

16 pins exposed at base bottom: and

Both free ends have an elastic force to open outward and at the same time the center is a leaf spring shape of a curved shape, the center is inserted or separated between the 16 pins, and keeps in close contact with each other when inserted, It is composed of a grounded conductive shunt connector jig detachable by holding and removing the quantum step when detaching.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, only the same components have the same reference numerals as much as possible even if shown on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a perspective view illustrating a shunt connector jig installed in a 16-pin connector according to an exemplary embodiment of the present invention. 3 is a cross-sectional view illustrating a shunt connector jig installed in a 16-pin connector according to an exemplary embodiment of the present invention. In this figure, only the portion where the 16-pin connector is located in the base assembly where the printed circuit board is not assembled is shown. Referring to the drawings,

The manufacturing process of the hard disk drive will be briefly described. After the assembly process, the fully assembled hard disk is subjected to the servolite process, and then the servolite process, then the functional test process, and the burn-in process are performed to test the performance. Next, the product is shipped through a post process such as a final test process to confirm that the hard disk drive set that has passed the burn-in process is normally defected.

In the above process, the present invention is used in the instrument assembly process, in particular, in the instrument assembly process, the shunt connector jig 30 of the present invention is used in the base assembly 1 state. In other words, it is a tool that can be used before assembly of a printed circuit board assembly (PCBA).

16 pins 202 into which the shunt connector jig 30 is inserted are fixed by the injection molding 201 with eight pins standing upright in two rows. The end of the pin 202 is sharp in shape, and the material is metal. This 16 pin 202 is inserted into the connector of the support plate that holds the flexible printed circuit connecting the head of the actuator.

The connector is connected to the actuator by a flexible printed circuit and then to a head installed at the free end of the suspension via an arm. The connector, actuator, flexible printed circuit, and the like are not shown in the drawings. Also, depending on the model, the same applies when there are 20 pins instead of 16 pins.

When the shunt connector jig 30 is inserted into the space between the 16 pins 202, the pin 202 and the shunt connector jig 30 are in intimate contact with each other. The reason for maintaining such an intimate state is that the quantum steps 301 and 302 of the jig have elastic force to open outward. The pin 202 also has an elastic force, and the jig 30 degrees has a leaf spring shape, and has an elastic force.

In addition, the jig is preferably a conductive material, thereby allowing the ground treatment. Moreover, a metal material or a rubber material is most preferable. This is because the metal or rubber is a material capable of satisfying both conductivity and elastic force at the same time. As a result, conductive metal or conductive rubber is the most preferred material.

The shunt connector jig has a length (horizontal length) between the quantum edges of 5 mm, an open gap of 0.8 mm, and a length of 3.7 mm. It is curved toward both ends 301 and 302, and the center is curved.

As described above, the sixteen pins 202 and the shunt connector jig 30 are kept in contact with each other to ground.

In detail, insert the shunt connector jig 30 into the 16 pin 20 exposed from the base assembly before assembling the hard disk drive assembly. The assembly of the hard disk drive assembly is then completed, and the shunt connector jig 30 is pulled out before the S / W (servo writer) or H / T (HDA function test). Then reinsert the shunt connector jig 30 after S / W and H / T. Remove the shunt connector pins before assembling the printed circuit board assembly and complete the printed circuit board assembly process.

Since the shunt connector jig 30 must be removed during the test process as described above, when the hard disk drive assembly is being assembled, standby, or moved, the shunt connector jig 30 must be used to maintain the ground state.

On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.

As described above, the present invention is effective in preventing ESD generated when waiting, storing, moving, and assembling in the base assembly state of the PCB assembly process during the hard disk drive assembly process. This prevents damage to the head.
