The present invention is an assembly of a simple structure by injection molding using plastics to assemble the head assembly in FDD, so that the performance of the head can be maintained and the noise generated during deformation and operation can be completely prevented. A head assembly of a floppy disk drive (FDD).

In the conventional case, in the assembly of the head assembly in the FDD, as shown in FIGS. 5 and 4, a stopper rod 10 is used as an iron plate, and an upper head arm 2 and a lower head arm 2 'are used. ), And the stopper rod 10 was used as an iron plate, and a separate steel shaft 11 was attached thereto to press the spring 7 to the fixed head. When assembling the lower head arm, the stopper rod made of steel is not only fixed, but also the spring plate of the upper head arm is lifted to the upper part to prevent deformation. In some cases, the quality was deteriorated due to the inability to maintain the precision. On the contrary, the parts are easily deformed even if they are precisely worked. If not only the lack of accuracy deformation during transport assembly of parts as well as a change in which the use occurs after assembly consumers, there are several drawbacks such as a complex assembly.

Therefore, the present invention has been devised to solve such a conventional drawback and the construction and operation effects will be described with reference to the accompanying drawings.

Injection molding of the upper head arm 2, to which the spring plate 1 is fixed, and then ejecting the upper head arm 2 and the lower head arm 2 'while the lower head arm 2' is also injection molded. The fixed fixing member 3 is fastened by a fixing screw, and the stopper portion 5 is integrally formed at both front sides of the fixing holder 3 while the protrusion 4 is integrally formed at the rear end of the upper head arm 2. The upper head arm 2 is lifted upward to prevent damage when the protrusion 4 is in contact with the stopper 5, and the spring fixing shaft 6 is integrally formed with the fixing holder 3. By inserting the spring (7) here, reference numeral 8, 8 'is the head and 9 is the disk.

The operational effects of the proposed paper thus constructed are as follows.

In the floppy disk drive head assembly of the present application assembled as described above, the spring plate 1 fixed to the rear end of the upper head arm 2 in order to insert and mount the disk 9 between the heads 8 and 8 '. The upper head arm 2 is operated while the upper head arm 2 is rotated, and the synthetic resin is made of synthetic resin as shown in FIG. 2 to prevent the spring plate 1 from being deformed or damaged due to excessive operation of the upper head arm 2. A stopper portion is formed on both sides of the front portion of the fixed holder 3 which is injection-molded with synthetic resin while the protrusion 4 is injection molded integrally with the upper head arm 2 to the rear of the upper end of the injection-molded upper head arm 2. (6) integrally injection molding with the fixing holder (3), when the upper head arm (2) is operated to the upper part and trying to force over a certain angle, the projection (4) of the upper head arm (2) first Stopper part 5 of the fixed holder (3) Since the operation of the upper head arm (2) is stopped while being caught by the spring plate (1) is excessively operated by the excessive operation of the upper head arm (2) can be prevented from being deformed or damaged as well as operating When the noise generated by the resonant shape is absorbed at the time of operation and it is operated in a state where the stopper rod made of iron plate and the spring plate of the upper head arm and the plane are not fixed, the noise of the opening of the head assembly occurs. The spring fixing shaft 6 which supports and fixes the spring 7 which is installed in order to prevent a defect and to increase the contact force of the upper head 8 and the lower head 8 'is the same as the conventional case. The injection molding was performed to allow the spring to have the contact force of the upper and lower heads with the spring shaft formed separately on the stopper rod surface. The spring fixing shaft 6 is integrally injection-molded in the fixed holder 3, and the spring 7 is inserted therein so as to increase the contact force of the heads 8 and 8 '. By injection molding integrally, not only the productivity is improved, but also the workmanship is reduced due to the stability of the product and the simplification of assembly, and the noise of the head assembly can be completely prevented.

Claims (1)
