[0029] Please refer to Figures 1 to 4 , to better understand the multi-layer circuit board device 10 of the present disclosure, the following further explains the multi-layer circuit board device 10:

[0030] A multi-layer circuit board device 10 according to an embodiment includes a control board 300 and an antenna board group 400. The control board 300 is provided with a first mounting hole 301, and the antenna board group 400 is provided with a second mounting hole 401. The multi-layer circuit board device 10 further includes a fixing member 100 and a locking member 200. The fixing member 100 includes a fixing member main body 110 and a support portion 120 protruding from the outer peripheral wall of the fixing member main body 110. The fixing member main body 110 is respectively passed through the first mounting hole 301 and the second mounting hole 401. The support portion 120 is located between the control board 300 and the antenna board group 400, and both ends of the support portion 120 are respectively abutted against the control board 300 and the antenna board group 400. The locking member 200 is sleeved on the fixing member main body 110 and connected to the fixing member main body 110. The locking member 200 is located on the side of the antenna board group 400 facing away from the control board 300.

[0031] As Figure 1 shown, in this embodiment, by arranging the fixing member 100 to pass through the control board 300 and the antenna board group 400 respectively, the control board 300 and the antenna board group 400 are connected in series. Immediately afterwards, the locking member 200 is sleeved on the fixing member 100 and connected to the fixing member 100. The locking member 200 is located on the side of the antenna board group 400 facing away from the control board 300, so that the control board 300 and the antenna board group 400 can be effectively locked and fixed, and thus the structural stability of the multi-layer circuit board device 10 is effectively enhanced.

[0032] Furthermore, the fixing member 100 includes a fixing member main body 110 and a support portion 120 protruding from the outer peripheral wall of the fixing member main body 110, so that the fixing member 100 does not need to be assembled separately. In this way, the assembly process of the multi-layer circuit board device 10 can be effectively reduced, thereby effectively enhancing the production efficiency of the multi-layer circuit board device 10, and further effectively enhancing the practicability of the fixing member 100.

[0033] As Figure 2 、 Figure 3 and Figure 4 shown, in one embodiment, the locking member 200 is a locking nut, and the fixing member main body 110 is screwed to the locking member 200. It can be understood that by arranging the locking member 200 as a locking nut and screwing the locking nut to the fixing member main body 110, the structural stability of the multi-layer circuit board device 10 can be effectively improved.

[0034] As Figure 1 shown, in one embodiment, the fixing member 100 is an insulating member. It can be understood that the fixing member 100 being an insulating member can effectively prevent the control board 300 and the antenna board group 400 from being electrically connected through the fixing member 100, thereby effectively preventing the control board 300 and the antenna board group 400 from short-circuiting, and further effectively ensuring that the multi-layer circuit board device 10 can work normally.

[0035] In one embodiment, the fixing member body 110 and the support portion 120 are an integrally formed structure, so that the fixing member 100 has good structural stability, so that the fixing member 100 can effectively lock and fix the control board 300 and the antenna board assembly 400, thereby effectively enhancing the structural stability of the multi-layer circuit board device 10 and making the components of the fixing member 100 simpler. This can effectively reduce the assembly process of the multi-layer circuit board device 10, thereby effectively improving the production efficiency of the multi-layer circuit board device 10.

[0036] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, the end of the fixing body 110 away from the antenna board assembly 400 is snapped into the first mounting hole 301. It can be understood that by snapping the end of the fixing body 110 away from the antenna board assembly 400 into the first mounting hole 301, the connection stability between the fixing body 110 and the control board 300 can be effectively improved.

[0037] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, one end of the fixing member body 110 adjacent to the locking member 200 is threadedly connected to the second mounting hole 401. It can be understood that by threading the end of the fixing member body 110 adjacent to the locking member 200 into the second mounting hole 401, the connection strength between the fixing member body 110 and the antenna board assembly 400 can be effectively improved, thereby effectively improving the overall structural stability of the multi-layer circuit board device 10.

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, a snap-fit portion is provided at one end of the fixing body 110 away from the antenna board assembly 400, and the snap-fit portion is snap-fitted into the first mounting hole 301. It is understood that by providing the snap-fit portion on the fixing body 110 to snap into the first mounting hole 301, the connection stability between the fixing body 110 and the control board 300 is ensured, thereby effectively preventing relative shaking of the fixing body 110 and the control board 300, thereby effectively improving the overall structural stability of the multi-layer circuit board device 10.

[0039] like Figure 2 、 Figure 3 and Figure 4As shown, in one embodiment, the antenna board assembly 400 includes a first antenna board 410 and a second antenna board 420. Second mounting holes 401 are defined in both the first antenna board 410 and the second antenna board 420. The first antenna board 410 and the second antenna board 420 are spaced apart from each other, and one end of the fixing member body 110 adjacent to the locking member 200 is screwed into the corresponding second mounting hole 401. It will be appreciated that by defining the second mounting holes 401 in both the first antenna board 410 and the second antenna board 420, the fixing member 100 can be screwed and secured to the first antenna board 410 and the second antenna board 420, respectively. This effectively ensures the stability of the connection between the fixing member 100 and the first antenna board 410 and the second antenna board 420, thereby effectively improving the structural stability of the multi-layer circuit board device 10.

[0040] like Figure 2 、 Figure 3 and Figure 4 As shown, in one embodiment, the multilayer circuit board device 10 further includes a separation sleeve 500, which is disposed between the first antenna board 410 and the second antenna board 420. The separation sleeve 500 is sleeved on the fixing member body 110. It will be appreciated that the separation sleeve 500 can effectively separate the first antenna board 410 and the second antenna board 420, preventing direct contact between the first antenna board 410 and the second antenna board 420. This prevents electromagnetic coupling between the first antenna board 410 and the second antenna board 420, thereby preventing damage to the usability of the multilayer circuit board device 10, thereby effectively improving the usability of the multilayer circuit board device 10.

[0041] The present disclosure further provides a wireless communication device, comprising the multilayer circuit board device 10 according to any one of the above embodiments.

[0042] In this example, a fixing member 100 is provided to pass through the control board 300 and the antenna board group 400 respectively, thereby connecting the control board 300 and the antenna board group 400 in series, and then the locking member 200 is sleeved on the fixing member 100 and connected to the fixing member 100. The locking member 200 is located on the side of the antenna board group 400 away from the control board 300. In this way, the control board 300 and the antenna board group 400 can be effectively locked and fixed, thereby effectively avoiding the control board 300 and the antenna board group 400 from shaking during the use of the multi-layer circuit board device 10, thereby effectively enhancing the structural stability of the communication equipment.

[0043] Furthermore, the fixing member 100 includes a fixing member body 110 and a support portion 120 protruding from the outer peripheral wall of the fixing member body 110. Because the support portion 120 is protruded from the outer peripheral wall of the fixing member body 110, the fixing member 100 does not need to assemble the fixing member body and the support portion 120. This can effectively reduce the assembly process of the multi-layer circuit board device 10, thereby effectively enhancing the production efficiency of the communication equipment.

[0044] Compared with the prior art, the present disclosure has at least the following advantages:

[0045] 1. By setting fixing parts to pass through the control board and the antenna board group respectively, the control board and the antenna board group are connected in series, and then the locking parts are put on the fixing parts and connected to the fixing parts. The locking parts are located on the side of the antenna board group away from the control board. In this way, the control board and the antenna board group can be effectively locked and fixed, thereby effectively preventing the control board and the antenna board group from shaking relative to each other, thereby effectively enhancing the structural stability of the multi-layer circuit board device.

[0046] 2. The fixing member includes a fixing member body and a support portion protruding from the outer peripheral wall of the fixing member body. Since the support portion is protruding from the outer peripheral wall of the fixing member body, the fixing member does not need to assemble the fixing member body and the support portion. This can effectively reduce the assembly process of the multi-layer circuit board device, thereby effectively improving the production efficiency of the multi-layer circuit board device.

[0047] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
