The expansion panel 10 of the server of the present embodiment includes a housing 100, an expansion electronic component 200, a conductive elastic sheet 300, an adhesive member 400, and a conductive cover 500.
The housing 100 is a casing made of metal or plastic material. The housing 100 has a receiving space S. In addition, the housing 100 further has a supporting portion 110, a supporting portion 120 and an opening 130. The bearing part 110 and the supporting part 120 are located in the accommodating space S. The bearing part 110 is, for example, a plastic column with a screw hole. The supporting portion 120 is, for example, a plastic plate. The opening 130 communicates with the accommodating space S.
The expansion electronic component 200 is located in the receiving space S and mounted to the housing 100. In addition, the expansion electronic component 200 includes a circuit board 210 and an expansion electrical connector 220. The circuit board 210 has a first surface 211 and a second surface 212 opposite to each other. The first surface 211 of the circuit board 210 faces the carrier 110. The expansion electrical connector 220 is disposed on the first surface 211 of the circuit board 210 and partially outside the housing 100 through the opening 130. In addition, the circuit board 210 further has a conductive pad 213 and a first through hole 214. The conductive pad 213 is disposed on the first surface 211 of the circuit board 210. The first through hole 214 penetrates the first surface 211 and the second surface 212.
The conductive elastic piece 300 is located in the receiving space S and mounted on the housing 100. The conductive elastic piece 300 includes a connecting segment 310, a first conductive segment 320, two second conductive segments 330, and a fastening segment 340. The first conductive segment 320 is connected to one side of the connecting segment 310 and sandwiched between the circuit board 210 and the carrier portion 110, that is, the first conductive segment 320 is stacked on the carrier portion 110.
The first conductive segment 320 includes a body portion 321 and two elastic protrusions 322. The body 321 is, for example, flat and connected to the connecting section 310. The main body 321 has a second through hole 3211. The two elastic protrusions 322 are located at two opposite sides of the second through hole 3211, and the two elastic protrusions 322 protrude from one side of the main body 321 away from the carrying portion 1100 and press against the conductive pad 213 of the circuit board 210. Thus, the quality of the electrical contact between the first conductive segment 320 and the conductive pad 213 of the circuit board 210 can be improved by the design of the two elastic protrusions 322.
In addition, the expansion panel 10 of the server may further include a first locking element 610, wherein the first locking element 610 penetrates through the first through hole 214 and the second through hole 3211 and is locked to the supporting portion 110, so as to fix the circuit board 210 and the conductive elastic piece 300 of the expansion electronic component 200 to the supporting portion 110.
In the present embodiment, the number of the elastic protrusions 322 is two, but not limited thereto. In other embodiments, the number of resilient protrusions may be only a single one.
Portions of both second conductive segments 330 are arc-shaped. The two second conductive segments 330 are connected to opposite sides of the connecting segment 310, and the first conductive segment 320 and the two second conductive segments 330 extend and protrude toward the same side of the connecting segment 310. In the present embodiment, the first conductive segment 320 and the two second conductive segments 330 both extend and protrude toward the same side of the connecting segment 310, but not limited thereto. In other embodiments, the first conductive segment and the two second conductive segments each extend and protrude toward different sides of the connecting segment.
The back-buckling section 340 is connected to the connecting section 310, and the first conductive section 320 and the two second conductive sections 330 protrude from the same surface of the connecting section 310. The back fastening segment 340 protrudes from the opposite side of the connecting segment 310. The connecting section 310 and the back-fastening section 340 are clamped together on the supporting portion 120. In addition, the back-buckle section 340 has a pressing structure 341, and the pressing structure 341 of the back-buckle section 340 can improve the clamping force between the conductive elastic piece 300 and the supporting portion 120.
In the embodiment, the number of the second conductive segments 330 is two, but not limited thereto. In other embodiments, the number of second conductive segments may be only a single.
The conductive cover 500 is mounted on the housing 100 and covers the accommodating space S. The conductive cover 500 is used to be mounted on a cabinet (not shown) of the server for grounding. In addition, the second conductive segment 330 abuts against the conductive cover 500 in an arc shape, so as to provide the quality of electrical contact between the second conductive segment 330 and the conductive cover 500.
In addition, the expansion panel 10 of the server may further include two second locking members 620. The conductive cover 500 is locked to the housing 100 by the second locking element 620.
In the present embodiment, the number of the second locking elements 620 is two, but not limited thereto. In other embodiments, the number of second locking elements may also be only a single one.
In the present embodiment, the assembly sequence of the extended electronic component 200, the conductive elastic piece 300 and the conductive cover 500 is, for example, to fix the conductive elastic piece 300 to the supporting portion 110 and the supporting portion 120 of the housing 100 in sequence. Then, the expansion electronic component 200 is stacked on the first conductive segment 320 of the conductive elastic piece 300. Then, the expansion electronic component 200 and the conductive elastic piece 300 are locked and fixed to the housing 100 by the first locking member 610. Then, the conductive cover 500 is locked to the housing 100 by the second locking element 620.
The first conductive segment 320 of the conductive clip 300 is electrically contacted to the conductive pad 213 of the circuit board 210, and the second conductive segment 330 of the conductive clip 300 is electrically contacted to the conductive cover 500 in an arc shape, so that an ElectroStatic Discharge (ESD) generated on the circuit board 210 is guided to the conductive cover 500 that is grounded through the conductive clip 300. Thus, the conductive elastic sheet 300 can be designed to prevent the electrostatic discharge phenomenon.
According to the expansion panel of the server in the embodiment, the first conductive segment and the second conductive segment of the conductive elastic sheet are respectively and electrically contacted with the circuit board and the conductive cover plate, so that the electrostatic discharge phenomenon generated on the circuit board can be conducted to the conductive cover body subjected to grounding treatment through the conductive elastic sheet, and the electrostatic discharge phenomenon is further avoided.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
