[0026] The coupling circuit board 100 includes a circuit board body 110 and at least one coupling member 150 .

[0027] The circuit board body 110 includes conductive circuit layers and dielectric layers that are stacked and alternately arranged in sequence, wherein the number of layers of the conductive circuit layer and the dielectric layer may include but are not limited to 10 layers, 20 layers, etc. respectively. The specific setting is based on actual needs and is not limited here. The dielectric layer may include but is not limited to insulating materials such as prepreg, epoxy resin, polyester resin (PET), polyimide, polyimide, polycarbonate (PC), bismaleimide triazine (BT), ceramic base, etc. The conductive circuit layer may include a copper layer, an aluminum layer, a silver layer, a nickel layer or an alloy layer, etc., which is not limited here.

[0028] The coupling element 150 is used to realize wireless connection of signals and energy between adjacent conductors by using different metal conductors, and realize functions such as filtering and voltage conversion according to the needs of the coupling circuit board 100.

[0029] At least one target hole 120 is provided on the circuit board body 110, and the target hole 120 penetrates at least a portion of the circuit board body 110; the target hole 120 is a hole structure specifically used for the built-in coupling member 150. The setting of the target hole 120 will avoid the conductive lines and the through holes of the circuit board body 110. The target hole 120 can be a through hole and / or a blind hole.

[0030] This embodiment is described by taking a target hole 120 and a coupling member 150 as an example. In other embodiments, the number of target holes 120 and coupling members 150 can be multiple, for example: 2, 3, 5, 6 or 10, etc., which is specifically set based on actual needs and is not limited here.

[0031] The coupling member 150 includes: a first metal tube 151 and a second metal tube 152 which are coaxially and spaced apart, the first metal tube 151 is fitted and fixedly arranged on the hole wall of the corresponding target hole 120, and the diameter of the first metal tube 151 is larger than that of the second metal tube 152. That is, in the target hole 120, the first metal tube 151 is coaxially sleeved with the second metal tube 152.

[0032] In the vertical direction Y of the circuit board body 110 , the first metal tube 151 and the second metal tube 152 at least partially overlap, and specifically may partially overlap or completely overlap. The overlapping portion of the first metal tube 151 and the second metal tube 152 may be coupled.

[0033] In a specific application scenario, the first metal tube 151 can be turned on, so that the second metal tube 152 receives the coupled energy and transmits it. In a specific application scenario, the second metal tube 152 can also be turned on, so that the first metal tube 151 receives the coupled energy and transmits it.

[0034] Through the above structure, the coupling circuit board of this embodiment includes a circuit board body and at least one coupling member, the circuit board body is provided with at least one target hole, the target hole penetrates at least a part of the circuit board body, and the coupling member includes: a first metal tube and a second metal tube which are coaxially and spaced apart, the first metal tube is in contact with and fixedly arranged on the hole wall of the corresponding target hole, and the diameter of the first metal tube is larger than that of the second metal tube; wherein, in the vertical direction of the circuit board body, the first metal tube and the second metal tube at least partially overlap, so that the coupling member is built into the circuit board body through the setting of the target hole, thereby realizing an integrated design of the coupling circuit board, broadening the three-dimensional space of the coupling circuit board, and realizing a high-density and high-integration design of the coupling circuit board.

[0035] In some embodiments, the space between the first metal tube 151 and the second metal tube 152 is filled with the dielectric member 160 ; and / or the interior of the second metal tube 152 is filled with the dielectric member 160 .

[0036] The dielectric member 160 may include, but is not limited to, insulating materials such as epoxy resin, magnetic powder, polyester resin (PET), polyimide, polyimide, polycarbonate (PC), bismaleimide triazine (BT), and ceramic-based materials.

[0037] Since the energy coupling effect of the coupling element 150 is determined by the coupling spacing, coupling area, and coupling medium, the corresponding parameters can be adjusted to obtain coupling amounts of different sizes and frequency bands.

[0038] The coupling area S=2πD*H, D is the diameter of the first metal tube 151, and H is the overlapping height between the first metal tube 151 and the second metal tube 152; the coupling distance △d=(Dd) / 2; the coupling coefficient K=(εr*S) / (4π*△d), where εr is the dielectric constant of the coupling medium.

[0039] In this embodiment, the energy coupling effect of the coupling element 150 can be adjusted by changing the diameters of the second metal tube 152 and the first metal tube 151 , the distance between the first metal tube 151 and the second metal tube 152 , and the type of dielectric element.

[0040] In some embodiments, the first metal tube 151 and the second metal tube 152 may be hollowed out; and / or the second metal tube 152 may be hollowed out to achieve coupling by air.

Next, the first metal tube 151 is solid-filled with other materials such as resin and magnetic powder, and then another small hole is drilled in the first metal tube 151 using drilling technology, with a drill diameter of d, and the electroplating technology is repeated to form a second metal tube 152. At this time, the first metal tube 151 and the second metal tube 152 form a ring coupling. When a signal passes through one of the holes, the other hole receives the coupling energy, and then the signal is transmitted through the transmission line connected to the hole.

[0042] In some embodiments, in the vertical direction Y of the circuit board body 110 , the first metal tube 151 and the second metal tube 152 completely overlap.

[0043] In practical applications, the complete overlap of the first metal tube 151 and the second metal tube 152 allows space for the second metal tube 152 to be left for the target conductive circuit 130 .

[0044] In some embodiments, the opposite ends of the first metal tube 151 and the opposite ends of the second metal tube 152 are respectively in contact with the opposite ends of the corresponding target hole 120. That is, the lengths of the first metal tube 151 and the second metal tube 152 are close to the lengths of the corresponding target hole 120, that is, one coupling member 150 is disposed throughout the entire target hole 120.

[0045] In practical applications, the length of the first metal tube 151 may also allow space for the second metal tube 152 to be left for the target conductive circuit 130 .
