Description

Technical Field

[0001] The invention relates to an electronic device, and in particular to a mainboard. Background Art

[0002] With the development of e-sports computers, players are no longer satisfied with the visual effects of the screen, but are more pursuing the auxiliary sound and light stimulation of peripheral equipment.

[0003] In a known gaming computer, an LED light module is installed around a heat sink, wherein the LED light module is electrically connected to a product providing a signal source (such as a motherboard) via a signal connection line disposed on the heat sink. Therefore, the design size of the LED light module is limited by the structural design of the motherboard, and when additional electronic components (such as an SSD or a memory) are installed, the heat sink must be removed first, and the heat sink with the signal connection line must also be removed. This can easily damage the signal connection line during the removal of the heat sink.

[0004] Furthermore, due to the internal structure of the gaming computer, the heat dissipation device occupies most of the space on the circuit board. Therefore, the LED light-emitting module used to display the optical effect can only be set at the edge of the circuit board, which limits the setting position of the LED light-emitting module. Summary of the invention

[0005] The object of the present invention is to provide a motherboard which is convenient for design and adjustment and easy for plugging and unplugging.

[0006] A motherboard of the present invention comprises a mainboard, a first plate, a second plate, a cable connector, a light strip and a light guide plate. The mainboard has a first connector; the first plate is located between the mainboard and the second plate; the cable connector comprises a cable, a second connector and a third connector, wherein the second connector and the third connector are respectively arranged at opposite ends of the cable, and the second connector is suitable for plugging with the first connector; the light strip comprises a circuit board, a plurality of LEDs and a fourth connector, wherein the LEDs are arranged on the circuit board, and the fourth connector is extended from one end of the circuit board, and the fourth connector is suitable for contacting with the third connector for electrical connection; the second plate is located between the light guide plate and the first plate.

[0007] In one embodiment, the first connector and the second connector are USB connectors.

[0008] In one embodiment, the third connector and the fourth connector are spring pin connectors.

[0009] In one embodiment, the third connector and the fourth connector are magnetically attracted to be positioned.

[0010] In one embodiment, the first plate and the second plate are heat dissipation plates.

[0011] In one embodiment, the mainboard further includes a plurality of heating elements disposed on the mainboard, and the second plate has a first area and a second area, wherein the light strip is disposed in the first area, and the light guide plate is disposed corresponding to the first area.

[0012] Based on the above, the motherboard can adaptably change the position of the light bar relative to the motherboard through the arrangement of the flat cable connector, which has design margin. In addition, the use of the flat cable connector allows the light bar to be easily plugged in and out, and other components that have a relative arrangement relationship with the light bar do not need to change their status, so it is convenient to use.

[0036] Figure 1A FIG. 1 is an exploded schematic diagram of a motherboard according to an embodiment of the present invention. Figure 1B for Figure 1A Please also refer to the assembly diagram of the motherboard. Figure 1A and Figure 1B The motherboard 100 of the present embodiment includes a mainboard 110 , a first plate 120 , a second plate 130 , a cable connector 140 , a light strip 150 and a light guide plate 160 .

[0037] The motherboard 100 of this embodiment can be applied to electronic devices such as gaming computers or desktop computers, wherein a portion of the motherboard 100 is structurally integrated with the housing of the electronic device to serve as a decoration of the electronic device as required, or can emit light to provide sensory stimulation or warning signals when the electronic device is in use.

[0038] In the motherboard 100 of the present embodiment, the mainboard 110 is the main body of the motherboard, which has a first connector 112 , wherein the first connector 112 may be a USB connector.

[0039] The first plate 120, the second plate 130 and the light guide plate 160 are all disposed on the main board 110, wherein the first plate 120 is located between the main board 110 and the second plate 130, and the second plate 130 is located between the light guide plate 160 and the first plate 120. In other words, in the assembly direction A, from bottom to top, they are the main board 110, the first plate 120, the second plate 130 and the light guide plate 160.

[0040] The flat cable connector 140 includes a flat cable 142, a second connector 144, and a third connector 146, wherein the second connector 144 and the third connector 146 are respectively disposed at opposite ends of the flat cable 142, the second connector 144 is adapted to be plugged with the first connector 112, and the third connector 146 is adapted to be fixed to the first plate 120. Specifically, the first plate 120 has a first positioning hole 122, and the third connector 146 can be locked to the first plate 120 and positioned in the first positioning hole 122 via a locking member, such as a screw.

[0041] As mentioned above, the first connector 112 and the second connector 144 are USB connectors, wherein one of the first connector 112 and the second connector 144 is a male connector of the USB connector, and the other of the first connector 112 and the second connector 144 is a female connector of the USB connector. Using the USB connector allows the first connector 112 and the second connector 144 to be firmly plugged into each other to maintain a good electrical connection.

[0042] The light bar 150 is disposed on the second plate 130, wherein the light bar 150 includes a circuit board 152, a plurality of LEDs 154, and a fourth connector 156. The LEDs 154 are disposed on the circuit board 152, and the LEDs 154 can emit light of the same color or light of different colors, depending on the needs. In addition, the LEDs 154 can be controlled by a program to emit light all together or partially.

[0043] The fourth connector 156 is extended from one end of the circuit board 152, wherein the fourth connector 156 and the LED 154 can be respectively disposed on two opposite surfaces of the circuit board 152. Specifically, in the case where the LED 154 is disposed on the top surface of the circuit board 152, the fourth connector 156 is disposed on the bottom surface of the circuit board 152, wherein the second plate 130 has a second positioning hole 132, and the fourth connector 156 is disposed in the second positioning hole 132, so as to facilitate the physical contact and electrical connection between the fourth connector 156 and the third connector 146 located below.

[0044] In this embodiment, the third connector 146 and the fourth connector 156 are spring pin connectors, wherein the third connector 146 is a male connector and the fourth connector 156 is a female connector, the spring pin is disposed at the female connector, and the male connector is provided with a signal input contact.

[0045] The spring pin connector is used for the electrical connection between the light bar 150 and the flat cable 142 connector 140, so that when the assembler assembles the second plate 130 onto the mainboard 110, the spring pins of the fourth connector 156 can be easily contacted with the signal input contacts of the third connector 146 by simply placing the second plate 130 onto the mainboard 110. Compared with the first connector 112 and the second connector 144 which use USB connectors and need to be aligned for plugging, the third connector 146 and the fourth connector 156 which use spring pin connectors have the advantage of being easy to implement physical contact and achieve electrical conduction.

[0046] Incidentally, the third connector 146 and the fourth connector 156 are positioned relative to each other by magnetic attraction. Specifically, a magnet may be provided on at least one of the third connector 146 and the fourth connector 156, so that when the second plate 130 is assembled to the main board 110, the third connector 146 and the fourth connector 156 may be guided to align relative to each other by the force of magnetic attraction, so that the assembly can be facilitated.

[0047] The motherboard 100 further includes a plurality of heating elements 114 disposed on the mainboard 110 , wherein the heating elements 114 on the mainboard 110 may be a central processing unit (CPU) or a graphics processing unit (GPU), but is not limited thereto, and may also be other electronic elements that generate heat.

[0048] The first plate 120 and the second plate 130 mentioned above can be heat sinks, and the first plate 120 is arranged to contact the heating element 114, wherein the size of the second plate 130 can be larger than the size of the first plate 120, which is conducive to further dissipating the heat transferred from the heating element 114 to the first plate 120 quickly through the second plate 130.

[0049] In addition, a layer of thermally conductive adhesive (not shown) may be disposed between the first plate 120 and the heating element 114 to facilitate the contact between the first plate 120 and the heating element 114 and enhance the heat dissipation effect.

[0050] Based on the above, the second plate 130 can also be roughly divided into a first area 130a and a second area 130b, wherein the light strip 150 is disposed in the first area 130a, and thus the light guide plate 160 is correspondingly disposed in the first area 130a. The location of the heating element 114 is not limited, and can be disposed corresponding to the first area 130a or the second area 130b, but in one embodiment, the heating element 114 can be disposed correspondingly in the second area 130b to prevent the heat emitted by the heating element 114 from affecting the light guide plate 160.

[0051] In summary, in the motherboard of the present invention, the position of the light bar relative to the motherboard can be adaptively changed by using the flat cable connector, so that the position design of the light bar has an adjustable margin.

[0052] In addition, by using the spring pin connector for the third connector and the fourth connector, when the second board is assembled to the mainboard, the third connector and the fourth connector can be in contact with each other in a simple manner to achieve electrical connection, thus having the advantage of being easy to assemble and disassemble. Furthermore, other components that are relatively arranged with the light bar do not need to change their arrangement positions or states due to the assembly or disassembly of the second board.
