Background technique

In today's society of electronic technology, many electronic products have been pervasive in our daily life. Electronic products are used in food, clothing, housing, transportation, education and entertainment. In addition, with the continuous advancement of electronic technology, More complex and more user-friendly electronic products are being introduced, and electronic products are also designed towards the trend of light, thin, short and small. Since the emergence of computers has greatly changed the way of life and lifestyle of human beings, computers have gradually become an indispensable and important tool in the life and work of ordinary people.

As far as servers and desktop computers (desktop) are concerned, they mainly include computer mainframes, monitors and computer interface devices, wherein computer mainframes include computer casings, motherboards, central processing units, memory, hard drives, and optical disk storage devices. However, in order to improve the performance of the host computer, such as image processing, audio processing, and external peripheral functions, there are usually many adapter card slots on the motherboard of the host computer for additional expansion cards such as graphics cards and sound cards.

Taking the known expansion card as an example, the expansion card usually includes a circuit board and a baffle plate (or bayonet iron sheet). The baffle has a plate portion and a bent portion. The circuit board is fixed to the plate portion of the bezel by screws. A hole is formed on the edge of the bent part. When the expansion card is installed to the computer mainframe, the bent part passes out of a backboard of the computer casing and presses against an installation part outside the backboard. The mounting part has screw holes corresponding to the broken holes of the bending part. When the screw passes through the hole of the bending part and is locked in the screw hole, the assembly of the expansion card can be completed through the interference between the screw and the structure of the bending part.

However, the bent portion of the expansion card baffle protrudes outside the computer case, and the outer side of the back panel must also form a protruding or recessed mounting portion correspondingly. As a result, the exterior of the computer casing is uneven and unattractive.

Detailed ways

FIG. 1 is a three-dimensional schematic diagram of an expansion card according to an embodiment of the present invention. Please refer to FIG. 1 , the expansion card 100 includes a circuit board 110 and a baffle 120 . The baffle 120 is located on one side of the circuit board 110 and has a plate portion 122 and a bent portion 124 connected to each other. The board portion 122 has a long hole H and is fixed to the circuit board 110 . Furthermore, the baffle 120 can also have at least one fixing portion 126 (two are shown in FIG. 1 ). The fixing portions 126 are fixed to the board portion 122 and extend from the board portion 122 toward the circuit board 110 , so that the board portion 122 is fixed to the circuit board 110 through the fixing portions 126 . In addition, in this embodiment, the plate portion 122 , the bent portion 124 and the fixing portions 126 can be integrally formed. In addition, in another non-illustrated embodiment, at least one connector opening can be formed on the board portion 122 for allowing at least one connector on the circuit board 110 to pass through to connect other interface devices or wires.

FIG. 2 is a three-dimensional schematic diagram of a casing according to an embodiment of the present invention, and FIG. 3 is a partial schematic diagram of the inside of the casing in FIG. 2 . Please refer to FIG. 2 and FIG. 3 , the casing 50 has a back plate 52 and at least one support portion 54 (five are shown in FIG. 1 ). The backplane 52 has a plurality of expansion card openings 56 . In this embodiment, a plurality of baffles 120' can be pre-configured on the backplane 52 to cover the opening 56 of the expansion card. Compared with the baffle 120, the baffle 120' does not have the fixing portion 126. When the expansion card 100 is to be installed on the motherboard (not shown), the baffle 120' is first removed from the backplane 52, and then fixed again. The baffle 120 of the expansion card 100 is on the supporting portion 54 . If the expansion card 100 is to be disassembled, only the baffle plate 120 and the support portion 54 are separated from each other. Therefore, there is no need to use screws and locking tools to facilitate the installation and removal of the expansion card 100 .

It is worth mentioning that since the bent portions 124 of the baffles 120, 120' extend from the plate portion 122 toward the side of the circuit board 110, that is, they extend from the plate portion 122 toward the inside of the housing 50, and neither of them protrudes. On the outside of the back plate 52, the appearance of the casing 50 looks more beautiful and flat.

4A-4C are schematic cross-sectional views of the assembly process of the expansion card of FIG. 1 and the casing of FIG. 2 . Please refer to FIG. 4A first, the long hole H of the plate portion 122 is adapted to be engaged with the supporting portion 54 so that the bezel 120 is fixed to the inside of the casing 50 . In detail, the supporting portion 54 can be a protrusion. The protrusion has a head 54 a and a rod 54 b, and protrudes from the back plate 52 . The diameter D1 of the head portion 54a is larger than the diameter D2 of the stem portion 54b. One end of the long hole H is formed with a large-diameter portion H1, and the other end is formed with a small-diameter portion H2.

Please refer to FIG. 4A and FIG. 4B , the baffle plate 120 can be installed on the protrusion (supporting portion 54 ) through the large aperture portion H1 . When the baffle 120 moves relative to the back plate 52 along the direction of the arrow A1 , the large aperture portion H1 is suitable for allowing the head 54 a to pass through. Referring to FIG. 4B and FIG. 4C , when the baffle 120 moves relative to the back plate 52 along the direction of the arrow A2 , the rod portion 54 b moves from the large aperture portion H1 to the small aperture portion H2 . At this time, the head portion 54 a interferes with the structures around the small aperture portion H2 , and the assembly process of the baffle plate 120 and the casing 50 can be completed. In this embodiment, the baffle 120 can form a tight fit relationship with the support portion 54 to prevent the baffle 120 from loosening. However, in another non-illustrated embodiment, the relative position of the baffle 120 and the back plate 52 can also be fixed by pressing and holding the bent portion 124 of the baffle 120 through other fixing parts (not shown).

To sum up, the expansion card and its baffle of the present invention can fix the baffle from the inside of the casing, and the bent portion of the baffle will not protrude outside the casing. Therefore, the utility model can maintain the flatness of the casing, and the appearance is more beautiful.

Although the utility model has been disclosed as above with a plurality of embodiments, it is not intended to limit the utility model. Anyone skilled in the art can make some changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the present utility model should be defined by the claims.
