【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a partially cutaway plan view showing a state of the memory card of the present invention in which a battery is housed, FIG. 2 is a partially cutaway plan view showing a state of the memory card of the present invention with a battery cover removed, and FIG. FIG. 4 is a sectional view showing a state in which the battery of the memory card of the present invention is discharged to the outside, FIG. 4 is a sectional view showing the IV-IV cross section of FIG. 3, and FIG. It is a perspective view shown.

In FIG. 1, 1 is a memory card, 11 is a surface shield plate made of a stainless steel plate, 12 is a frame, and 13 is a printed circuit board on which an IC memory is mounted.

In FIG. 1, a memory card 1 has a built-in battery 2 for storing stored data. The battery 2 is housed in a battery storage recess 3 of the memory card 1 and covers the battery storage recess 3. A lid 4 is provided. When the locking recess 41 is formed in the battery cover 4, the locking projection 51 of the locking piece 5 is engaged with the locking recess 41, and the battery cover 4 cannot be unintentionally removed. Reference numeral 6 denotes a pressing elastic piece made of foam such as silicon rubber, and the elasticity presses the locking piece 5 against the locking recess 41 of the battery lid 4. It is preferable to use a foamed material such as silicon rubber as the pressing elastic piece because it is easier to mount than a coil spring.

Reference numeral 7 denotes an electrode connecting metal fitting, which supplies power from the battery 2 to the IC chip mounted on the printed circuit board 13 through the electrode connecting metal fitting 7. In the present invention, the electrode connecting metal fitting 7 has a cross-section connector. A U-shaped base 72 is formed, and the base 72 having a U-shaped cross section is fitted to the end of the frame 12 of the memory card 1 and / or the printed circuit board 13, thereby facilitating attachment of the electrode connection fitting. It is characterized by

When the spring piece 71 having elasticity is formed on the electrode connection fitting 7, as shown in FIG. 2, the locking piece 5 provided on the frame 12 of the memory card 1 is moved in the X direction and locked. At the same time as the engagement protrusion 51 of the piece 5 and the engagement recess 41 of the battery lid 4 are disengaged, the elasticity of the spring piece 71 of the electrode connecting fitting 7 causes the battery 2 and the battery lid 4 to move to the memory card 1. This is preferable because the battery 2 is pushed out and the battery 2 can be easily discharged to the outside of the memory card 1 as shown in FIG. Here, a new battery 2 is inserted into the battery storage recess 3, the battery cover 4 is covered, and the locking recess 41 of the battery cover 4 and the locking projection 51 of the locking piece 5 are engaged to replace the battery. It can be done easily.

As shown in a sectional view in FIG. 4, when the U-shaped base portion 72 of the electrode connecting fitting 7 is fixed so as to sandwich the frame 12 of the memory card 1 and the end portion of the printed circuit board 13, these are fixed. Although it is possible to prevent the frame 12 and the printed circuit board 13 from peeling off, the battery electrode 14 of the printed circuit board 13 and the electrode connection fitting 7 are connected to each other by using the auxiliary connecting fitting 8 having a U-shaped cross section shown in FIG. The projection 81 formed in the notch formed in 12 and formed in the auxiliary connecting fitting 8 having a U-shaped cross section is connected to the battery electrode 14 of the printed circuit board 13, and the base portion 72 having a U-shaped cross section of the electrode connecting fitting 7 is connected. It is preferable that the battery electrode 14 of the printed circuit board 13 and the electrode connecting fitting 7 are electrically connected to each other by being connected to, because the thickness can be further reduced.

[Effect of the device]

 As described above, according to the present invention, the electrode connecting metal fitting for the electrode of the battery is arranged in the battery accommodating concave portion provided in the memory card, and the electrode connecting metal fitting is formed with a U-shaped base in cross section. The U-shaped cross-section base of the connection fitting is fitted to the frame of the memory card and / or the printed circuit board on which the IC memory is mounted, and power is supplied to the IC memory through the electrode connection fitting. It has the advantages that the connection fittings can be easily attached and the memory card can be made thinner.
