The method of electrical connection can refer to the method of electrical connection of the first printed circuit board 210 and the second printed circuit board 220, which will not be repeated here.

[0047] The electronic device 10 of the embodiment of the present application further includes a controller, which is disposed on the circuit board 200. In some implementations, the controller may include at least one of a central processing unit (CPU) and a system on chip (SOC).

[0048] Please refer to Figure 5 The electronic device 10 of the embodiment of the present application further includes a radio frequency connector 300. The radio frequency connector 300 may include at least one of a radio frequency coaxial connector and a dual-core symmetrical radio frequency connector 300.

[0049] The RF connector 300 includes a first connector 310 and a second connector 320, wherein one of the first connector 310 and the second connector 320 may include a male connector of the RF connector 300, and the other may include a female connector of the RF connector 300. For example, the first connector 310 may include a female connector, and the second connector 320 may include a male connector.

[0050] The first connector 310 is provided on the circuit board 200. In some implementations, the first connector 310 can be inserted into the circuit board 200, or the first connector 310 can be soldered to the circuit board 200. The second connector 320 is detachably connected to the first connector 310 to achieve an electrical connection between the second connector 320 and the first connector 310. In some implementations, the second connector 320 can be plugged into the first connector 310. Alternatively, the second connector 320 can be threadedly connected to the first connector 310. Alternatively, the second connector 320 can be snap-fitted to the first connector 310.

[0052] In an optional embodiment, please combine Figure 3 and Figure 5 The electronic device 10 further includes an antenna 600 and a support member 700. The antenna 600 is configured to transmit or receive electromagnetic waves. The support member 700 is disposed on the housing 100, and the antenna 600 is disposed on the support member 700. In other embodiments, the support member 700 may also be disposed on the circuit board 200. The antenna 600 is electrically connected to the second connector 320, and is electrically connected to the circuit board 200 and the controller via the RF connector 300.

[0053] In some implementations, the antenna 600 may include a first radiator 610 and a second radiator 620, the first radiator 610 and the second radiator 620 being spaced apart, and the first radiator 610 and the second radiator 620 operating in different frequency bands.

Through the above configuration, the distance between the antenna 600 and the RF connector 300 is reduced, the length of the cable is shortened, thereby reducing costs and transmission loss.

[0055] Please refer to Figure 6 The electronic device 10 further includes an auxiliary device 400. Here, the auxiliary device 400 can be understood as a device originally provided by the electronic device 10 for achieving functions such as heat dissipation, heat conduction, and electrical connection. The auxiliary device 400 can be provided on the housing 100 (e.g. Figure 1 As shown), or the auxiliary device 400 can also be arranged on the circuit board 200.

[0056] The auxiliary device 400 has an abutment portion 410, and in the first direction x, the abutment portion 410 is spaced apart from the circuit board 200. The first direction x can be perpendicular to the circuit board 200. In some implementations, the first direction x can be the thickness direction of the notebook body 11 (e.g., Figure 1 ), or the first direction x can also be the thickness direction of the mobile phone or tablet computer (as shown Figure 2 shown).

[0057] Based on the above configuration, the RF connector 300 is located between the circuit board 200 and the abutting portion 410 , and the abutting portion 410 abuts against the second connector 320 .

[0058] Through this arrangement, the auxiliary device 400 can press the second connector 320 against the first connector 310, preventing the second connector 320 from loosening and ensuring a stable connection between the first connector 310 and the second connector 320, thereby ensuring a stable electrical connection. Furthermore, by using the existing auxiliary device 400 of the electronic device 10 to press against the first connector 310, the introduction of new components into the electronic device 10 is avoided, reducing the thickness of the electronic device 10 and saving costs.

[0059] In some implementations, such as Figure 6 As shown, the abutting portion 410 can abut against the second connector 320 along the first direction x, thereby, the force exerted by the abutting portion 410 on the second connector 320 is parallel to the first direction x. In other embodiments, the abutting portion 410 can also abut against the second connector 320 along other directions, and the force exerted by the abutting portion 410 on the second connector 320 can have a predetermined angle with the first direction x. For example, the force exerted by the abutting portion 410 on the second connector 320 can be perpendicular to the first direction x.

[0060] Please refer again Figure 3In an optional embodiment, the auxiliary device 400 further includes a vapor chamber 420. The vapor chamber 420 is disposed within the housing 100 and spaced apart from the circuit board 200. In some implementations, the vapor chamber 420 can be stacked with the circuit board 200. In a plane parallel to the circuit board 200, the projection of the vapor chamber 420 and the projection of the circuit board 200 at least partially overlap.

[0061] Please refer to Figure 7 The vapor chamber 420 comprises a first cavity 421, a second cavity 422, a first channel 425, and a second channel 426. The first channel 425 and the second channel 426 both connect the first cavity 421 and the second cavity 422. Condensate is contained within the first cavity 421. After the condensate absorbs heat and vaporizes, the gas enters the second cavity 422 through the first channel 425. The gas releases heat and liquefies within the second cavity 422. The liquefied condensate then returns to the first cavity 421 through the second channel 426.

[0062] Please combine Figure 3 and Figure 7 Based on the above structure, the heat sink 420 can be used to dissipate heat from the first device on the circuit board 200. For example, the first device may include a heat generating device among electronic components, and the first device may also include a controller.

[0063] Exemplarily, the first device is connected to the heat spreader 420, and the heat generated by the first device is conducted to the condensate in the first cavity 421. The condensate absorbs the heat and vaporizes, and liquefies and dissipates the heat in the second cavity 422 to conduct the heat to the outside of the heat spreader 420, thereby achieving heat dissipation for the first device.

[0064] In the above embodiment, the first cavity 421 can be arranged closer to the first device on the circuit board 200 than the second cavity 422. For example, the first cavity 421 can be arranged near the middle of the vapor chamber 420, and the second cavity 422 can be arranged near one end of the vapor chamber 420.

[0065] In some implementations, multiple first and second cavities 421, 422 may be provided to improve heat absorption or heat dissipation efficiency. For example, second cavity 422 may include a first chamber 423 and a second chamber 424. First chamber 423 may be located near one end of vapor chamber 420, while second chamber 424 may be located near the other end of vapor chamber 420.

[0066] In an optional embodiment, the heat spreader 420 may be connected to the middle frame 150 to conduct heat to the middle frame 150 and improve the heat dissipation effect.

[0067] In an optional embodiment, the area of ​​the heat spreader 420 may be larger than the area of ​​the circuit board 200 to improve the heat dissipation effect.

[0068] In some implementations, the material of the vapor chamber 420 may include at least one of oxygen-free copper, sintered copper, and the like.

[0069] In an optional embodiment, a heat conducting member is provided on the vapor chamber 420, and the heat conducting member has thermal conductivity and elasticity. The heat conducting member is provided between the vapor chamber 420 and the first component, and elastically contacts the vapor chamber 420 and the heating component. Thus, the heat conducting member can reduce the contact thermal resistance between the vapor chamber 420 and the heating component, thereby improving the heat conduction efficiency. In some implementations, the material making up the heat conducting member can include at least one of silicone, silicone grease, and the like.

[0070] In some implementations, a first shielding member is provided on the heat spreader 420, a second shielding member is provided on the circuit board 200, and the first shielding member and the second shielding member are connected. Figure 3 As shown, a heat spreader 420, a first shielding member, a second shielding member, and a circuit board 200 are stacked. The first shielding member and the second shielding member both extend in a plane parallel to the circuit board 200. The heat spreader 420, the first shielding member, the second shielding member, and the circuit board 200 enclose a shielding cavity, and the second device is disposed within the shielding cavity. The second device may include electronic components that generate electromagnetic radiation, and the second device may also include a controller. Here, the first device and the second device may comprise the same device.

[0071] Through the above arrangement, the heat spreader 420, the first shielding member, the second shielding member and the circuit board 200 can prevent the electromagnetic radiation of the second device from transmitting outside the shielding cavity, and at the same time, can also prevent the electromagnetic radiation outside the shielding cavity from transmitting into the shielding cavity.

[0072] In some implementations, the material of the first shielding member may include at least one of conductive foam, rubber, and the like; the material of the second shielding member may include at least one of metal materials such as nickel silver, stainless steel, and tinplate.

[0073] In the above embodiment, a plurality of the first shielding member and a plurality of the second shielding member may be provided.

[0074] Based on the above configuration, the antenna 600 can be disposed outside the shielding cavity to avoid mutual interference between the antenna 600 and the second device. The RF connector 300 can be disposed outside the shielding cavity.

[0075] Please combine Figure 3 and Figure 6 In an optional embodiment, the abutment portion 410 and the heat spreader 420 are an integral structure. In some implementations, the abutment portion 410 may include an area on the heat spreader 420 that is at least partially used for absorbing or dissipating heat. For example, Figure 3As shown, the abutting portion 410 may include at least a portion of the vapor chamber 420 within the dotted line range.

[0076] Based on the above arrangement, the abutting portion 410 of the existing vapor chamber 420 of the electronic device 10 abuts against the first connector 310, thereby avoiding the need for new components within the electronic device 10 and reducing the thickness of the electronic device 10. Furthermore, if space within the electronic device 10 is limited, not introducing new components can prevent the size of the vapor chamber 420 from being affected, ensuring the heat absorption or heat dissipation effects, as well as the electromagnetic shielding effect of the vapor chamber 420.

[0077] Please continue to refer to Figure 3 The electronic device 10 of the embodiment of the present application further includes a fan 430, which is disposed in the housing 100.

The blades 432 are connected to the main shaft of the motor, and the motor is used to drive the blades 432 to rotate to generate airflow. The motor can be electrically connected to the controller.

[0078] In some implementations, the housing 100 is provided with an opening, and the direction of the airflow of the fan 430 is from the air outlet of the fan 430 toward the opening. Figure 3 F is a possible direction of the airflow of the fan 430, which may be parallel to the second direction y. The vapor chamber 420 may be located between the air outlet and the opening of the fan 430, so that the airflow of the fan 430 passes through the vapor chamber 420 to improve heat dissipation efficiency.

[0079] In the above embodiment, the airflow of the fan 430 may pass between the heat sink 420 and the circuit board 200 .

[0080] Please combine Figure 3 and Figure 7 In an optional embodiment, the heat spreader 420 is provided with a second cavity 422 , one end of which is located at the air outlet of the fan 430 .

The first fan 433 and the second fan 434 are spaced apart and can be respectively disposed on both sides of the circuit board 200. For example, the first fan 433 and the second fan 434 are respectively disposed on both sides of the first printed circuit board 210, with the first fan 433 located between the first printed circuit board 210 and the second printed circuit board 220, and the second fan 434 located between the first printed circuit board 210 and the third printed circuit board 230.

[0082] Based on the above structure, one end of the heat spreader 420 having the first chamber 423 can be located at the air outlet of the first fan 433, and the other end of the heat spreader 420 having the second chamber 424 can be located at the air outlet of the second fan 434, thereby further improving the heat dissipation efficiency of the heat spreader 420.
