Hard disk case

This creation relates to a hard disk case, especially a hard disk case made of metal and plastic.

Since the development of technology, portable hard drives have become a storage and backup device for modern people. The larger the capacity of the hard disk, the larger the internal components, the larger the volume will be. In the technology, as the structure of the hard disk case, the metal is initially used as a whole case. Because the metal is hard enough to properly protect the internal hard disk, it is difficult to consider the weight of the metal and the processing. In order to alleviate the inconvenience of the user, the manufacturer has changed the outer casing to reduce the weight of the hard disk.

However, the metal shell and the plastic shell have their disadvantages in use, respectively, as stated below.

Referring to FIG. 11, the hard disk case 91 made of metal is heavy in weight as described above. If the user wants to carry the hard disk on the body, the excessive weight may cause trouble to the user; After the hard disk is processed, it will be marked with specifications on the outer casing or add some color to show the characteristics of the label. In the case of metal shells, the processing method of the metal shell 91 can be limited due to the material, usually The information is transferred onto the sticker, and then the sticker is attached to the outside of the metal shell 91. In addition, if the metal shell 91 is to be colored or has some decorative texture on the surface, it is difficult to process, so the processing is performed. The metal shell actually has many limitations; and, when the two metal shells as the outer cover are fastened, the metal stamping has its limit, so the joint cannot be effectively reduced, and thus the seam is left. The unsightly engagement slit 92 also has its disadvantages in appearance.

Because of the above shortcomings, some manufacturers have turned to plastic shells to make hard disk casings. The weight of plastics is lighter than that of metals. Moreover, the processing mode of injection molding enables the plastic surface to directly process the information that the operator wants to display. For example, the specifications of the hard disk or the information related to the brand plate, compared with the metal shell, need to be attached with a sticker or processed again. The plastic shell not only saves the processing procedure, but also saves the cost of secondary processing.

However, the main disadvantage of the plastic case is that the plastic is not resistant to impact, so even if there are many advantages in processing, once the hard disk is hit, the outer casing of the plastic case is difficult to protect the most important substrate structure inside, so it is very high. The risk will cause the hard disk to be damaged. Compared with the shortcomings of the metal case, the plastic case cannot effectively protect the hard disk and the hard disk is subject to a high risk of damage. It is also one of the most unpleasant shortcomings of the user.

Further, the first casing of the plastic material is made of injection molding technology. The precision of the fastening groove can be improved, that is, the seam can be reduced to achieve an aesthetic effect, and further, because of the injection molding, the pattern of the user's desired design can be easily processed on the first casing or even The information about the hard disk, in other words, compared to the metal casing, it is necessary to use the sticker to attach information or special processing on the metal surface to create the texture design. The creation can easily overcome the metal on the first casing. The inconvenience of the outer casing in this respect can also reduce the cumbersome feeling caused by the all-metal material through the first casing.

As for the second casing made of metal, compared with the all-plastic casing, the creation effectively improves the resistance to falling and durability through the second casing, so that the user has better resistance, and the user does not have to be as full. The plastic case is generally worried that the hard disk case may easily cause damage to the internal hard disk after it has been dropped.
