Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention particularly relates to a flash memory card case that can be easily and quickly assembled and reduce costs.

[0002]

[Prior art]

 Generally, a flash memory card is used as a storage body of a digital camera or the like, and is mainly used to record video captured by a digital camera.

[0003] Further, a case is used for the general flash memory card, and the case for the flash memory card has a case body made of a plastic material, and the case body is integrally bonded to a metal upper lid by ultrasonic waves. You.

However, the above structure causes the following problems when actually used. 1. When assembling a plastic case body and a metal top cover in a conventional flash memory card case, first align the top cover with the case body, and then integrate the case body and the top cover by ultrasonic bonding. Since they are joined, there are disadvantages that the combination is troublesome, the combination takes time, and the injection is difficult. In addition, since the upper lid is set to be thin in order to provide a space for incorporating an electronic member therein, it is necessary to adopt a metal material. 2. When combining the case body and the top lid, it is necessary to use a device that generates ultrasonic waves. However, since this device is very expensive, the cost is high.

[0005]

Means for Solving the Problems The present invention comprises a case body (10) and an upper lid (20), and a plurality of engaging holes (12) are formed at predetermined intervals on an upper peripheral edge of the case body (10). At the same time, engaging protrusions (22) corresponding to the respective engaging holes (12) are provided on the bottom peripheral edge of the upper lid (20), and the respective engaging convex portions (22) are engaged in the respective engaging holes (12). A case for a flash memory card, wherein the upper lid (20) and the case body (10) are integrally joined by being positioned.

[0006]

[Action]

 The present invention solves the above-mentioned problem, and forms a plurality of engaging holes at predetermined intervals on an upper peripheral edge of a case main body, and provides an engaging convex portion corresponding to each engaging hole on a bottom peripheral edge of an upper lid, By engaging and positioning each of the engaging projections in each of the engaging holes, the upper lid and the case body are securely joined together. As a result, the combination can be performed easily and quickly, and the cost can be surely reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0008]

[Preferred Embodiment of Invention]

 FIG. 1 is a perspective view of a flash memory card case according to the present invention, FIG. 2 is an exploded perspective view of the flash memory card case according to the present invention, and FIG. 3 is a perspective view of the flash memory card case according to the present invention. FIG. 4 is a partial cross-sectional view showing a state in which the engaging convex portion is being engaged with the engaging hole. FIG. 4 is a view showing a state after the engaging convex portion of the flash memory card case according to the present invention is engaged with the engaging hole. It is a sectional view.

As shown in FIGS. 1 and 2, the flash memory card case of the present invention includes a case body (10) made of a plastic material and an upper cover (20) made of a metal material. A plurality of engaging holes (12) are formed at predetermined intervals in the upper peripheral edge, and each of the engaging holes (12) is constituted by an upper tapered hole (14) and a lower positioning hole (16), The tapered hole (14) has a shape narrowing downward.

[0010] Furthermore, on the bottom periphery of the upper lid (20) made of the metal material, engaging projections (22) corresponding to the engaging holes (12) are provided, and on both sides of each engaging convex (22). An L-shaped hook portion (24) projecting outward is provided, a slit (26) is formed between the hook portions (24), and a curved portion (242) is formed outside each hook portion (24). ) Is formed.

As shown in FIG. 3, when the engaging projection (22) at the bottom of the upper lid (20) is engaged with the engaging hole (12) of the case body (10), the lower part of the upper lid (20) is The plurality of engaging projections (22) in the case body correspond to the respective engaging holes (12) in the case body (10), and the hook portions (24) on both sides of the engaging convex portion (22) respectively correspond to the engaging holes (12). The upper lid (20) is pressed from above by contacting the mortar-shaped tapered hole (14) downward. At this time, the hook portions (24) on both sides are pushed toward the slit (26) formed therebetween.

Then, as shown in FIG. 4, after pressing the plurality of engaging projections (22) at the bottom of the upper lid (20) downward, the hook (24) of the engaging projection (22) is tapered. When passing through the hole (14), it is engaged with the positioning hole (16) by elastic force.

[0013]

[Effect of the invention]

 Since the present invention has the above configuration, the following effects can be obtained. 1. When assembling the upper lid and the case body in the flash memory card case of the present invention, it is possible to combine them simply by simply engaging each of the engaging projections on the upper lid with the engaging holes in the case body, respectively. Therefore, the configuration is very simple and the combination can be performed quickly. 2. When assembling the upper lid and the case body of the flash memory card case of the present invention, each engaging projection on the upper lid is simply fitted into the engaging hole in the case body without performing the ultrasonic bonding process as in the related art. Since it is possible to combine them simply by engaging them together, the structure is very simple and the cost can be reduced.
