1. Field of the Invention
The invention is generally related to a computer case and more particularly to a computer case designed to facilitate assembly of cards.
2. Description of Related Art
In the present age of information and multimedia, computers have become one of the indispensable tools in our daily life. The type and quantity of interface cards which must be used in computers is increasing with the diversely development of computer applications. In prior art, screws are most commonly used to fasten the interface cards to computer case. However, this increases not only the number of screws used and also the steps of fastening. And steps of screw fastening using screw drivers are needed and it is rather time consuming. In addition, replacing the interface cards is quite often required in computers. The interface cards disassembling process may lead to problems of screw falling and cause short circuit or the surrounding components damaged. Moreover, the screws are often lost when they fall off into a computer case and it increases more problems for computer users.
The present invention is directed to a computer case capable of fixing a card without screws.
The present invention is directed to a computer case for fixing a card. The computer case includes a main case and a fixing unit. The main case includes a first wedging portion and a limiting portion. The fixing unit includes a compressing portion, a second wedging portion and at least one lug. The compressing portion compresses a fixing side of the card to fix the card. The second wedging portion is at a first side of the compressing portion. The lug is stretching from the compressing portion and located at a second side of the compressing portion. After the lug of the fixing unit and the limiting portion of the main case are connected, the first wedging portion of the main case and the second wedging portion of the fixing unit are wedged to fix the fixing side of the card on the main case.
According to an embodiment of the invention, the computer case further includes a card frame at the main case, wherein a plurality of openings are disposed on the card frame and the openings are capable for accommodating the fixing side of the card. In addition, the limiting portion is located at the main case. The first wedging portion is disposed at the card frame. Furthermore, the computer case can further include a fixing frame fixing to the main case and the fixing frame is placed above the openings of the card frame. The limiting portion and the first wedging portion are at the fixing frame.
According to an embodiment of the invention, the first wedging portion defines is an opening. The second wedging portion is a protrusion which is capable to be embedded into the opening.
According to an embodiment of the invention, the compressing portion has a plurality of baffles compressing the fixing side of the card.
According to an embodiment of the invention, the compressing portion includes a plurality of elastic slices to increase the elastic stress and align the heights of the compressing portion for the baffles to compress the fixing side of the card more closely.
According to an embodiment of the invention, the fixing unit is an elastic element.
According to an embodiment of the invention, the material of the main case is metal.
According to an embodiment of the invention, the limiting portion is an arch bridge for the lug to pass through.
In light of the foregoing, the computer case of the present invention is capable for fixing the card by locking the fixing unit to the main case. It is rather convenient to use and the overall shortcomings caused by screw fixing can also be avoided.
In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanying figures are described in detail below.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
The back wall 1120 has a plurality of openings P10, at least one first wedging portion 1122 and at least one limiting portion S10 (two limiting portions are illustrated in
Referring to
According to above descriptions, the computer case 1000 in this embodiment is capable for the card 100 to be simply and rapidly fixed by using the fixing unit 1200 whether the number of card 100 is one or in a plurality. It is no longer required operating with the screw drivers for fixing the cards 100 in this design, so the labour hours for assembling and the component costs are significantly reduced. Thus, the convenience is increased for the computer users in assembling process while replacing the cards 100. It is also no need to worry about the falling off screws in the computer case may damage the other expensive components.
Referring to
Moreover, in an embodiment, the limiting portion S10 is at the main plate 1124 and the first wedging portion 1122 is at the card frame 1126. The limiting portion S10 is designed as an arch bridge and the space below the arch bridge is for inserting the lug 1220. The limiting portion S10 can be used to limit the lug 1220 be able to merely move along the Z direction. A guiding inclined plane S12 (illustrated in
Furthermore, the compressing portion 1210 has, for example, a plurality of elastic slices 1212 and a plurality of baffles 1214. The places of the elastic slices 1212 correspond to the openings P10 and can be formed at the opening of U-crack cleaving at the compressing portion 1210, but the appearances and the shapes are not limited in present invention. When there is no external force exerting thereon, the elastic slices 1212 are slightly protruding from the compressing portion 1210 toward the below direction in the
In this embodiment, the first wedging portion 1122 is the opening of a plate which is in parallel with the XY plane, while the second wedging portion 1230 is the protrusion of a plate on the fixing unit 1200 which is in parallel with the XY plane. The first wedging portion 1122 can also be the protrusion while the second wedging portion 1230 can be the opening. Certainly, the first wedging portion 1122 and the second wedging portion 1230 can be replaced with any other appropriate wedging design and the details are not iterated herein.
In order to supply sufficient strength, in general, metal or other material with better strength is selected for the main case 1100, and plastic or other appropriate elastic material is selected for the fixing unit 1200. Plastic material can be used as the material of the fixing unit 1200 to avoid the card 100 being scratched and also reduce the costs and the overall weight.
In summary, in the computer case of the present invention, the card is fixed by wedging the fixing unit to the main case. The computer case of the present invention is provided with the advantages of having the capability of simply and rapidly fixing the cards without using the screw drivers, reducing the labour hours of assembling process and component costs, increasing the convenience of replacing cards and reducing the overall risks of the surrounding components get damaged.
Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
