Description

Technical Field

[0001] This utility model relates to an electronic component, and more particularly to an electronic component that includes an expansion card module. Background Technology

[0002] In recent years, with increasing demands for data transfer speeds, solid-state drives (SSDs) have gradually replaced traditional hard drives due to their superior data transfer capabilities. Furthermore, to drive the miniaturization of electronic devices, manufacturers introduced the M.2 form factor, and most SSDs are currently designed based on this form factor.

[0003] However, currently, solid-state drives (SSDs) compliant with the M.2 form factor do not support hot-swapping. Therefore, when it is necessary to replace or repair an SSD, the power to the electronic device containing the SSD must still be turned off, and the device's casing must be opened to remove the SSD, which causes inconvenience for SSD replacement or repair. Utility Model Content

[0004] The purpose of this invention is to provide an electronic component that uses a sensing component to switch the power supply of a circuit board so that the expansion card module supports hot-swapping functionality.

[0005] An embodiment of this utility model discloses an electronic component for electrical connection to a power supply device and includes a circuit board, a sensing component, and at least one expansion card module. The circuit board is electrically connected to the power supply device. The sensing component is disposed on and electrically connected to the circuit board. The at least one expansion card module includes a mounting box and an expansion card. The mounting box includes a housing and an operating body. The operating body has a first assembly side and a second assembly side opposite to each other. The first assembly side is pivotally connected to one side of the housing, allowing the operating body to include a closed position and an open position. The expansion card is disposed in the mounting box and electrically connected to the circuit board. When the operating body is in the closed position, the second assembly side engages with the housing, and the sensing component causes the circuit board to supply power from the power supply device to the expansion card. When the operating body is in the open position, the second assembly side disengages from the housing, and the sensing component causes the circuit board to stop supplying power from the power supply device to the expansion card.

[0006] According to one embodiment of the present invention, the sensing component includes a Hall sensor disposed and electrically connected to the circuit board, and the mounting box further includes a magnet disposed on the operating body and adjacent to the Hall sensor.

[0007] According to one embodiment of the present invention, the sensing component includes at least one light sensor disposed and electrically connected to the circuit board, the at least one light sensor being adjacent to the second assembly side of the operating body.

[0008] According to one embodiment of the present invention, the number of the at least one light sensor is multiple, and the multiple light sensors are respectively adjacent to the first assembly side and the second assembly side.

[0009] According to one embodiment of the present invention, it further includes at least one slide rail assembly, which includes two slide rails fixed to the circuit board, and the housing is slidably disposed on the two slide rails.

[0010] According to one embodiment of the present invention, one of the two slide rails has a first latching structure, and the first assembly side has a second latching structure. The first latching structure and the second latching structure are matching concave-convex structures. When the operating body is in the closed position, the first latching structure and the second latching structure are engaged with each other. When the operating body is in the open position, the first latching structure and the second latching structure are disengaged from each other.

[0011] According to one embodiment of the present invention, the sensing component includes at least one light sensor, which is disposed and electrically connected to the circuit board, and the at least one light sensor is adjacent to the first snap-fit ​​structure and the second snap-fit ​​structure.

[0012] According to one embodiment of the present invention, it further includes at least one connector disposed and electrically connected to the circuit board, one side of the expansion card being electrically connected to the at least one connector, and the mounting box further includes a positioning member disposed in the box body and positioning the expansion card away from the at least one connector.

[0013] According to one embodiment of the present invention, it further includes a fan and a heat dissipation fin assembly. The circuit board has a hole, the fan covers the hole and is electrically connected to the circuit board, and the heat dissipation fin assembly is located on one side of the fan and is in thermal contact with the housing.

[0014] According to one embodiment of the present invention, the heat dissipation fin assembly includes a plurality of fins arranged along an arrangement direction and having a plurality of grooves, the plurality of grooves being located on the plurality of fins, and the extending direction of the plurality of grooves being parallel to each other with the arrangement direction.

[0015] According to the electronic component disclosed in the above embodiments, when the operating body is in the closed position, the sensing component causes the circuit board to supply power from the power supply device to the expansion card. Furthermore, when the operating body is in the open position, the sensing component causes the circuit board to stop supplying power from the power supply device to the expansion card. In other words, with the assistance of the sensing component, the circuit board supplies power when the expansion card is installed and cuts off power when the expansion card needs to be replaced or repaired. This enables the expansion card to support hot-swapping, making the replacement and repair of the expansion card more convenient. Attached Figure Description

The following embodiments further illustrate the viewpoints of this utility model in detail, but are not intended to limit the scope of this utility model in any way.

[0057] Please see Figures 1 to 4 . Figure 1 This is a perspective view of an electronic component according to an embodiment of the present invention. Figure 2 for Figure 1 An exploded view of the electronic components. Figure 3 for Figure 2 An exploded view of the expansion card module of the electronic components.

[0058] In this embodiment, the electronic component 10 is electrically connected to a power supply device (not shown) and includes, for example, a circuit board 100, two slide rail assemblies 150, two connectors 160, two sensing components 200, two expansion card modules 300, a fan 400, and a heat sink assembly 450.

[0059] The circuit board 100 is used for electrical connection to a power supply device and has a hole 101. A baffle 102 can be fixed to one side of the circuit board 100. To clearly illustrate the technical features of this invention, [details omitted]. Figure 2 The baffle 102 is omitted from the diagram. Hereinafter, since the two slide rail assemblies 150, two connectors 160, two sensing components 200, and two expansion card modules 300 have similar detailed structures, the detailed structure of one corresponding set of slide rail assemblies 150, connectors 160, sensing components 200, and expansion card modules 300 will be described by example. In this embodiment, the slide rail assembly 150 includes two slide rails 151. The two slide rails 151 are fixed to the circuit board 100. The connector 160 is disposed and electrically connected to the circuit board 100. Furthermore, one of the two slide rails 151 has a first snap-fit ​​structure 152. Additionally, the connector 160 conforms to, for example, the M.2 specification. The two slide rail assemblies 150 can be connected to each other via a plate 155.

[0060] The sensing component 200 is disposed and electrically connected to the circuit board 100. Specifically, in this embodiment, the sensing component 200 includes a Hall sensor 210 and a plurality of light sensors 221, 222, and 223. The Hall sensor 210 and the light sensors 221, 222, and 223 are disposed and electrically connected to the circuit board 100.

[0061] In this embodiment, the expansion card module 300 includes a mounting box 310 and an expansion card 320. The mounting box 310 includes, for example, a housing 311, an operating body 312, a magnet 313, and a positioning member 314. The housing 311 includes, for example, a base 3110 and a cover plate 3111. The cover plate 3111 is disposed on one side of the base 3110. The operating body 312 has a first assembly side 315 and a second assembly side 316 opposite to each other. The first assembly side 315 is pivotally connected to one side of the base 3110 and has a second latching structure 317. The first latching structure 315 and the second latching structure 317 are matching concave-convex structures and are used to engage with each other. The second assembly side 316 is used to detachably engage with the base 3110. The magnet 313 is disposed on the operating body 312 and adjacent to the Hall sensor 210. A positioning element 314 is disposed within the housing 311. Specifically, the positioning element 314 is disposed in a limiting groove 3113 of the cover plate 3111 and has a positioning protrusion 3140. A magnet 3141 can be accommodated within the positioning element 314. The magnet 3141 is used to attract multiple magnets 3116 on the cover plate 3111 to position the positioning element 314 on the cover plate 3111. These magnets 3116 are arranged, for example, in pairs, separately from each other on the cover plate 3111 to position the positioning element 314 at different positions on the cover plate 3111, thereby allowing the positioning element 314 to secure expansion cards 320 of different lengths.

[0062] The housing 311 is slidably mounted on two slide rails 151. Two light sensors 221 and 222 are located adjacent to the first assembly side 315 and the second assembly side 316, respectively, and another light sensor 223 is located adjacent to the first snap-fit ​​structure 152 and the second snap-fit ​​structure 317.

[0063] The expansion card 320 is disposed in the housing 311 of the mounting box 310. Specifically, the expansion card 320 is disposed in the limiting groove 3113 of the cover plate 3111. One side of the expansion card 320 is electrically connected to the connector 160, and through the connector 160, it is electrically connected to the circuit board 100. Furthermore, the side of the expansion card 320 away from the connector 160 is positioned by the positioning protrusion 3140 of the positioning member 314. Additionally, a limiting plate 3115 can be fixed to one side of the cover plate 3111. The positioning member 314 and the limiting plate 3115 together hold the expansion card 320.

[0064] The fan 400 covers the perforation 101 and is electrically connected to the circuit board 100. The heat sink fin assembly 450 is located on one side of the fan 400 and is in thermal contact with the housing 311. In this embodiment, the heat sink fin assembly 450 includes a plurality of fins 451 arranged along an arrangement direction A and has a plurality of grooves 452. These grooves 452 are located on the fins 451, and the extending direction E of these grooves 452 is parallel to each other with the arrangement direction A. That is, the heat sink fin assembly 450 in this embodiment adopts a segmented design. In this embodiment, the fan 400 covers the perforation 101 so that the cool air guided by the fan 400 can be more concentrated and blown onto the heat sink fin assembly 450.

[0065] Please see Figure 2 , Figure 4 and Figure 5 , Figure 5 To present Figure 1 A partially enlarged top view of the operating body of the expansion card module of the electronic components in the open position. In this embodiment, the first assembly side 315 is pivotally connected to one side of the housing 311, such that the operating body 312 includes a closed position (e.g., Figure 4 (as shown) and an opening position (as shown) Figure 5 (As shown).

[0066] like Figure 2 and Figure 4 As shown, when the operating body 312 is in the closed position, the second assembly side 316 engages with the housing 311 and the sensing component 200 enables the circuit board 100 to supply power from the power supply device to the expansion card 320. In addition, the first latching structure 152 and the second latching structure 317 engage with each other to provide a foolproof effect.

[0067] like Figure 2 and Figure 5 As shown, when the operating body 312 moves from the closed position to the open position along a pivoting direction P, the second assembly side 316 separates from the housing 311 and the sensing component 200 causes the circuit board 100 to stop supplying power from the power supply device to the expansion card 320.

[0068] For example, this embodiment uses two mechanisms—magnetic field sensing and optical sensing—to determine the position of the operating body 312. Regarding the magnetic field sensing mechanism, since the Hall sensor 210 is adjacent to the magnet 313 disposed on the operating body 312, the Hall sensor 210 can determine the position of the operating body 312 based on the magnetic field generated by the magnet 313. Regarding the optical sensing mechanism, two optical sensors 221 and 222 are respectively adjacent to the first assembly side 315 and the second assembly side 316, and another optical sensor 223 is adjacent to the first latching structure 152 and the second latching structure 317. Therefore, the optical sensors 221, 222, and 223 can receive the light refracted or reflected by the operating body 312, thereby determining the position of the operating body 312.

[0069] In this embodiment, using three light sensors 221, 222, and 223 to determine the position of the operating body 312 is solely for improving sensing accuracy. In other embodiments, only one light sensor, particularly light sensor 221, may be used to determine the position of the operating body.

[0070] It should be noted that in other embodiments, the position of the operating object may be determined using only one of the magnetic field sensing and light sensing mechanisms. That is, in other embodiments, the sensing component may not need to include a light sensor or a Hall sensor. In embodiments where the sensing component does not include a Hall sensor, the mounting box may not need to include a magnet. In still other embodiments, the sensing component may not need to include both a light sensor and a Hall sensor, but instead may include a microswitch connected to the operating object to determine the position of the operating object.

[0071] According to the electronic component disclosed in the above embodiments, when the operating body is in the closed position, the sensing component causes the circuit board to supply power from the power supply device to the expansion card. Furthermore, when the operating body is in the open position, the sensing component causes the circuit board to stop supplying power from the power supply device to the expansion card. In other words, with the assistance of the sensing component, the circuit board supplies power when the expansion card is installed and cuts off power when the expansion card needs to be replaced or repaired. This enables the expansion card to support hot-swapping, making the replacement and repair of the expansion card more convenient.

[0072] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the claims appended to this specification.
