Abstract

PURPOSE:To eliminate the necessity of provision of a lead wire which will be easily disconnected and soldering work of the read wire by connecting a coil with a wiring pattern with signal terminal rods and metallic fittings. CONSTITUTION:A bobbin 7 around which a coil 4 is wound and a terminal board 9 with signal terminal rods 8 connected with the coil 4 and planted in the board 9 are constituted to one body and the signal terminal rods 8 are passed through through holes 2a, 3a, and 10a which are respectively provided in a gimbal spring 2, base plate 3, and wiring pattern 10, with metallic fittings 11 being put between the rods 8 and hole walls. Thus the signal terminal rods of a coil device with signal terminals put in a slider are mechanically and electrically connected and fixed to the wiring pattern with the metallic fittings. Therefore, necessity of soldering works and disconnection can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head device for a flexible disk device, and particularly to an improvement in its assembly means.

[Conventional technology]

FIGS. 4A and 4B are a front view and a side view showing a state in which a conventional magnetic head device of this type is being assembled.

Figure 5 is a front view and a side view showing the state after assembly. In these figures, +11 is the slider, (2) is the gimbal spring that is polymerized with this, and (3) is the gimbal spring that is polymerized and bonded to the bottom surface. (4) is the coil fitted into the slider, (5) is the back bar of the slider, and (6) is the lead for connecting the coil (4) to the wiring pattern on the board (3). It is a line.

[Problem to be solved by the invention]

In conventional magnetic head devices, it is necessary to pull out the lead wire of the coil fitted in the slider and solder it to the wiring pattern on the substrate (3), and there is also the problem of breakage of the lead wire.

The object of the present invention is to eliminate the above-mentioned soldering work and wire breakage in order to solve the above-mentioned problems.

[Means to solve the problem]

In the case of this invention, the bobbin (7) around which the coil (4) is wound is
) and a terminal block (9) on which a signal terminal bar (8) connected to the coil is planted are integrated, and the signal terminal bar (8)
) in the gimbal spring (2), the board (3), and the through holes (2a) (3a) provided in the wiring pattern α on its top surface.
(1 oa), and a stopper α between this and the through hole.
D is inserted.

[For production]

In the magnetic head device of the present invention, a co-coil signal terminal bar with a signal terminal is fitted onto the slider.

It is mechanically and electrically connected and fixed to the wiring pattern on the board using a fastener.

〔Example〕

An embodiment of this invention will be described below. That is, in FIGS. 1, 2, and 3, the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals, and redundant explanation thereof will be omitted. 4)
and a bobbin (7) wound with.

The signal terminal bar (8) connected to this coil is integrated with the terminal block (9) on which it is planted to form a co-coil with a signal terminal as shown in Fig. 2, and this co-coil with a signal terminal is connected to the first As shown in the figure, it is fitted onto the slider (1), while the gimbal spring (2) is glued to the bottom surface and the wiring pattern +I is attached to the top surface.
The substrate (3) with Q itself.

Each of the gimbal spring (2) and the wiring pattern α1 has a through hole (3a) (
2a) (+ oa) were provided in a series, and each of the above signal terminal rods (8) inserted into these through holes was inserted between each through hole and the signal terminal rod as shown in Figure 3. It is characterized in that it is mechanically and electrically connected with a stopper αυ.

〔Effect of the invention〕

The magnetic head device of the flexible disk drive of this invention is constructed as described above, and the coil and the wiring pattern are connected by the signal terminal bar and the stopper, so that there is no need to connect the lead wire or its solder, which is likely to break. This has the effect that no work is required, and the slider alone can be easily attached and detached.
