Description

Electronic Components and Servers

The present invention relates to an electronic component and a server, in particular to an electronic component and a server including a protective cover.

Generally, a Trusted Platform Module (TPM) component is provided on the motherboard in the server to encrypt the hard disk. In addition, in order to prevent the trusted platform module element from being easily removed from the motherboard by a deliberate person, a protective cover is usually fixed on the motherboard through rivets to cover the trusted platform module element.

However, the exposed rivets are easily broken or pried open with tools and cannot effectively maintain the protective cover in a state covering the trusted platform module components. In addition, different thicknesses of circuit boards require the use of rivets of different specifications, which increases the cost of mounting the protective cover on the circuit board. Furthermore, since the rivet needs to pass through the motherboard to achieve the required tightening force, the rivet will protrude from the side of the motherboard close to the casing of the server to occupy the space between the motherboard and the casing.

The present invention is to provide an electronic component and a server so that the protective cover can be installed on circuit boards of different thicknesses, and at the same time effectively protect the electronic components and reduce the space occupied between the circuit board and the casing.

The other side of the stopper blocks the buckle structure to prevent the cover body from moving away from the top surface of the circuit board. The cover body covers the top surface of the circuit board, and the cover body and the circuit board together form an accommodating space. Electronic components are located in the accommodating space.

In this embodiment, the flanges 243 are adjacent to the two snap structures 242 , and the flanges 243 protrude out of the cover body 241 in a direction away from the accommodating space 260 and bear against the top surface 212 of the circuit board 210 . In addition, in this embodiment, the flange 243 surrounds the cover body 241 . As such, the flange 243 increases the difficulty of prying the cover 241 off the top surface 212 of the circuit board 210 .

In addition, in this embodiment, at least a part of the buckle structure 242 protrudes from the bottom surface 211 of the circuit board 210 . Furthermore, in this embodiment, the cover body 241 , the two snap structures 242 and the flange 243 are integrally formed, for example, but not limited thereto. In other embodiments, the cover body, the two snap structures and the flanges can also be combined structures.

Please refer to Figure 5 and Figure 6. FIG. 5 is a partial enlarged view of the side view of the electronic assembly of FIG. 1 detached from the casing. FIG. 6 is a partial enlarged view of a schematic side cross-sectional view of the electronic component of FIG. 1 when the buckle structure is not blocked by a stopper. After the screw 250 is detached from the casing 100 and the circuit board 210 is detached from the casing 100 , since at least part of the buckle structure 242 protrudes from the bottom surface 211 of the circuit board 210 , the operator can easily pull the buckle The portion of the structure 242 protruding from the bottom surface 211 separates the two snap structures 242 from the stops of the two second portions 232 of the two stoppers 230 , thereby removing the protective cover 240 from the circuit board 210 along the disassembly direction D1 .

Please refer to Figure 4 and Figure 6. In this embodiment, each of the two snap structures 242 includes a guide slope 2420 . When the protective cover 240 is mounted on the circuit board 210 along a mounting direction D2 opposite to the dismounting direction D1, the two guiding inclined surfaces 2420 respectively guide the two snap structures 242 so that the two second portions 232 of the two stoppers 230 are guided respectively. They are respectively stopped at one side of the two buckle structures 242 . In other embodiments, the two-buckle structure does not need to include a guiding slope.

In other embodiments, the buckle structure does not need to protrude from the bottom surface, and the operator can also insert his finger into the through hole of the circuit board or use a tool to move the buckle structure.

It should be noted that, in other embodiments, the circuit board may only include one through hole, the electronic component may only include one stopper, and the protective cover may include only one snap structure. In addition, in the embodiment in which the protective cover includes only one snap structure, the flange may not need to surround the cover but only on one side of the cover adjacent to the snap structure. Alternatively, in other embodiments, the protective cover does not need to include a flange. In still other embodiments, the electronic component may also include a plurality of electronic components and a plurality of protective covers.

In addition, in other embodiments, the circuit board does not need to include a through hole and the second portion of the stopper extends in a direction away from the circuit board to stop the protective cover.

Furthermore, in other embodiments, the cover body and the stopper of the protective cover may be respectively provided with a first buckle structure and a second buckle structure, and the first buckle structure and the second buckle structure are matched. the concave-convex structure. In this way, the cover body can be prevented from moving away from the top surface of the circuit board through the engagement between the first buckle structure and the second buckle structure.

The protective cover of the present invention is not limited to a circuit board provided in a single thickness. See Figure 7. 7 is a partial enlarged view of a schematic side sectional view of an electronic component according to another embodiment of the present invention. In this embodiment, the thickness T2 of the circuit board 210a is, for example, 0.062 inches. Since the buckle structure 242a of the protection cover 240a is stopped by the stopper 230a instead of the circuit board 210a, the protection cover 240a can be disposed on the circuit board 210a with reference to the method described in the first embodiment. It should be noted that, in other embodiments, the protective cover may also be disposed on a circuit board with a thickness between 0.062 inches and 0.118 inches or a circuit board with other thicknesses.

According to the server and electronic components disclosed in the above-mentioned embodiments, since the buckle structure of the protective cover is stopped by the stopper fixed to the circuit board instead of the circuit board, the thickness of the circuit board does not affect the protection The latching structure of the cover and the blocking relationship between the blocking pieces. In this way, the protective cover can be installed on circuit boards with different thicknesses through the snap-fit structure.

In addition, since the snap structure and the second part of the stopper are located in the through hole of the circuit board, it is difficult to damage the snap structure and the second part of the stopper from the outside. In this way, the protective cover can effectively protect the electronic components.

Furthermore, since the side of the second part of the stopper which is far away from the first part is between the bottom surface and the top surface of the circuit board and does not protrude from the bottom surface of the circuit board, the jamming caused by the stopper can be reduced. The space occupied by the buckle structure between the circuit board and the casing.

In an embodiment of the present invention, the electronic component of the present invention can be applied to a server, and the server can be used for artificial intelligence (AI) computing, edge computing (edge computing), and can also be used as 5G Server, cloud server or car network server use.

Although the present invention is disclosed above by the aforementioned embodiments, it is not intended to limit the present invention. Anyone who is familiar with the similar arts can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The scope of patent protection of the invention shall be determined by the scope of the patent application attached to this specification.
