1 is the ground plate of the present invention. The earth plate 1 is made of, for example, a copper alloy such as beryllium copper having a high electric conductivity and a spring property (elasticity), and its structure is formed by pressing one plate as shown in FIG. Bent at a right angle,
A curved portion 1a is formed on one side of the surface in order to take advantage of springiness,
The other surface is similarly formed with a corrugated portion 1b. Further, a convex portion is formed at an extended portion of the F-shaped portion 1b, and a tip portion of the convex portion (hold case engaging portion)
1c is bent at a right angle in the same direction as the curved portion 1a. Reference numeral 2 is a shield case, and 3 is a hold case incorporating magnetic head components such as a magnetic core 3a, a coil, a shield plate, terminals 3b, and a gap spacer. (The hold case 3 is usually composed of two parts, each of which has the above-mentioned magnetic head components incorporated therein, and then assembled into a screw, a u-shaped spring,
It is fixed with a clip. ) Figure 2 (a),
(B) shows a state in which the hold case 3 is incorporated in the shield case 2 using the ground plate 1 of the present invention. When assembled in the shield case 2, the hold case 3 is attached to the upper surface of the ground plate 1 so that the corrugated portions 1b of the ground plate 1 face each other, while the curved portion 1a of the ground plate 1 is applied to the side surface of the hold case 3. Also, the tip 1c of the ground plate 1
After contacting the tip of the hold case 3 as well, it is inserted into the shield case 2.

In the description of the present invention, the shape formed on the ground plate 1 is limited to the curved shape or the heave (wave) shape, but it is a shape for making the best use of the spring property, so long as the structure is such that the spring property is utilized. The shape is not particularly limited. Therefore, by using the ground plate 1 of the present invention, the hold case 3
Is pressed against the inner walls of the shield case 2 in the up-down, left-right direction, and positioning can be facilitated. In addition, as in the example,
If the tip 1c provided on the earth plate 1 can be attached to the hold case 3 and inserted,
It can be easily inserted into the shield case 2 and can be reliably positioned.

As described above, the number of parts can be reduced because the one that conventionally used two types of earth springs is used as one earth plate. Moreover, one surface of the metal piece can be used to construct the magnetic head. It is possible to press and hold the built-in hold case against the inner wall of the horizontal reference plane in the shield case, and further press it against the inner wall of the vertical reference plane in the shield case for positioning and grounding. When the hold case incorporating the magnetic head components is inserted into, the integrated ground plate is used to facilitate the assembling work and the positioning.
