[0016] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0017] In one aspect, the present application provides a connector 100, such as Figure 1 As shown, Figure 1The connector 100 may generally include a first circuit board 10 and at least two second circuit boards 20 , wherein the at least two second circuit boards 20 are fixedly disposed on the first circuit board 10 .

[0018] Among them, in this embodiment, if Figure 1 As shown, there is one first circuit board 10 and two second circuit boards 20 . Both second circuit boards 20 are arranged on the first circuit board 10 and are located on the same side of the first circuit board 10 to reduce the volume of the connector 100 .

[0019] Of course, in another embodiment, the number of first circuit boards 10 can be one, and the number of second circuit boards 20 can be three, four or five, etc., and the multiple second circuit boards 20 are all arranged on the same side of the first circuit board 10 and connected to the same surface of the first circuit board 10 to reduce the volume of the connector 100.

[0020] In other optional embodiments, the number of first circuit boards 10 can also be two, and the two first circuit boards 10 are stacked. The number of second circuit boards 20 can be at least two, and the at least two second circuit boards 20 can be arranged on the same side of one of the first circuit boards 10, or can be arranged on opposite sides of the two first circuit boards 10, which is not specifically limited in the embodiments of the present application.

[0021] Furthermore, if Figure 1 As shown, at least two second circuit boards 20 are arranged in parallel and spaced apart. With this arrangement, on the one hand, it is convenient to arrange electronic components such as capacitors and resistors on the surface of the second circuit board 20 to save space and reduce the volume; on the other hand, it can also prevent the circuits on adjacent second circuit boards 20 from contacting each other, thereby causing short circuits or signal crosstalk.

[0022] Among them, Figure 1 and Figure 2 As shown, Figure 2 yes Figure 1 At least two first electromagnetic components 12 are disposed on the first circuit board 10, at least one second electromagnetic component 22 is disposed on each second circuit board 20, and each first electromagnetic component 12 is electrically connected to each second electromagnetic component 22.

[0023] Specifically, in this embodiment, four first electromagnetic components 12 are disposed on the first circuit board 10 , the number of the second circuit boards 20 is two, and each second circuit board 20 is disposed with two second electromagnetic components 22 .

[0024] Among them, see Figure 2 and Figure 3 , Figure 3 yes Figure 2 The first circuit board 10 includes a substrate 11, a magnetic core 13, a transmission line layer 15 and a plurality of conductive members 17.

[0025] In this embodiment, an annular groove 112 is provided on the substrate 11; the magnetic core 13 is accommodated in the annular groove 112; the transmission line layer 15 is provided on opposite sides of the substrate 11, and each transmission line layer 15 includes a plurality of conductor patterns 152 arranged at intervals along the circumference of the annular groove 112; a plurality of conductive members 17 are provided along the inner and outer circumferences of the magnetic core 13, and are used to sequentially connect the conductor patterns 152 on the two transmission line layers 15, thereby forming a coil loop capable of transmitting current around the magnetic core 13. The magnetic core 13, the transmission line layer 15, and the plurality of conductive members 17 constitute a first electromagnetic element 12 provided on the substrate 11.

[0026] The structure of the second circuit board 20 is the same as that of the first circuit board 10 , please refer to the description in the above embodiment. The magnetic core 13 , the transmission line layer 15 and the plurality of conductive members 17 constitute a second electromagnetic element 22 disposed on the substrate 11 .

[0027] Specifically, each magnetic core 13 is correspondingly accommodated in an annular receiving groove 112 on the substrate 11, and the cross-sectional shape of the magnetic core 13 is substantially the same as the cross-sectional shape of the annular receiving groove 112, so that the magnetic core 13 can be accommodated in the annular receiving groove 112. The cross-sectional shape of the magnetic core 13 can be circular, square, elliptical, etc. Correspondingly, the shape of the annular receiving groove 112 can be circular, square, elliptical, etc., which is not specifically limited in the embodiment of the present invention.

[0028] In this embodiment, the magnetic core 13 can be formed by stacking a number of annular sheets in sequence, or by winding a narrow and long metal material, or by sintering a number of metal mixtures. There are many ways to form the magnetic core 13, which can be flexibly selected according to different materials, and this application does not limit it.

[0029] The magnetic core 13 can be an iron core, or can be composed of various magnetic metal oxides, such as manganese-zinc ferrite and nickel-zinc ferrite. Among them, manganese-zinc ferrite has the characteristics of high magnetic permeability, high magnetic flux density and low loss, and nickel-zinc ferrite has the characteristics of extremely high resistivity and low magnetic permeability. The magnetic core 13 in this embodiment uses manganese-zinc ferrite as a raw material and is sintered at high temperature.

[0030] Furthermore, a plurality of conductive members 17 are disposed around the inner and outer peripheries of the magnetic core 13. The conductive members 17 disposed on the inner periphery of the magnetic core 13 are internal conductive members 17a, and the conductive members 17 disposed on the outer periphery of the magnetic core 13 are external conductive members 17b. In this embodiment, the conductive members 17 may be metal layers. For details, please refer to Figure 3 First, a plurality of through holes may be formed on the substrate 11 located at the inner periphery of the magnetic core 13 and the outer periphery of the magnetic core 13, and then a conductive layer may be formed on the inner wall of the through hole by, for example, electroplating, coating, etc. The material of the metal layer includes but is not limited to copper, aluminum, iron, nickel, gold, silver, platinum group, chromium, magnesium, tungsten, molybdenum, lead, tin, indium, zinc or alloys thereof.

[0031] In another embodiment, the conductive member 17 may be a metal column. For example, a plurality of through holes may be first formed on the substrate 11 located at the inner periphery of the magnetic core 13 and the outer periphery of the magnetic core 13, and then the metal column may be inserted into the through holes. The diameter of the metal column is less than or equal to the diameter of the through hole in which it is located, and the material of the metal column is the same as that of the metal layer in the previous embodiment, which will not be described in detail here.

[0032] Among them, Figure 3 As shown, in this embodiment, a transmission line layer 15 is respectively provided on two opposite sides of the substrate 11. The transmission line layer 15 can be made of a metal material. The metal material used to form the transmission line layer 15 includes but is not limited to copper, aluminum, iron, nickel, gold, silver, platinum group, chromium, magnesium, tungsten, molybdenum, lead, tin, indium, zinc or any alloy thereof.

[0033] Continue reading Figure 2 and Figure 3 Each transmission line layer 15 includes a plurality of conductor patterns 152 ( Figure 4 ). Each conductor pattern 152 is connected across a corresponding internal conductive member 17a and an external conductive member 17b, and one end is electrically connected to the internal conductive member 17a, and the other end is electrically connected to the external conductive member 17b. Therefore, the internal conductive member 17a and the external conductive member 17b are sequentially connected to the conductor patterns 152 on the transmission line layer 15 located on opposite sides of the substrate 11, thereby forming a coil loop that can surround the magnetic core 13.

[0034] Specifically, the coil loop includes multiple turns of coils connected in sequence. In this embodiment, each turn of coil includes an inner conductive member 17a, a conductor pattern 152 located on one side of the substrate 11, an outer conductive member 17b, a conductor pattern 152 located on the other side, and the next inner conductive member 17a connected in sequence.

[0035] The number of coil loops wound around each magnetic core 13 may be one or more. For example, when the number of coil loops is one, an inductor element is formed. When the number of coil loops is multiple, a transformer or a filter is formed.

[0036] Furthermore, the coil loop wound around each magnetic core 13 is not completely closed, but is disconnected in the middle to form an input end and an output end. The signal enters the coil loop from the input end, and the signal passes through the coil loop and is output through the output end.

[0037] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the axial direction of the magnetic core 13 in the first electromagnetic element 12 and the axial direction of the magnetic core 13 in the second electromagnetic element 22 are perpendicular to each other.

[0038] Specifically, the axial direction of the magnetic core 13 in the first electromagnetic element 12 is parallel to the normal direction of the plane where the first circuit board 10 is located, that is, Figure 2 The axis direction of the magnetic core 13 in the second electromagnetic element 22 is parallel to the normal direction of the plane where the second circuit board 20 is located, that is, Figure 2 In this embodiment, by setting the axial direction of the magnetic core 13 in the first electromagnetic element 12 and the axial direction of the magnetic core 13 in the second electromagnetic element 22 to be perpendicular to each other, the first circuit board 10 and the second circuit board 20 can be vertically connected, thereby facilitating the routing design of the coils of the first electromagnetic element 12 and the second electromagnetic element 22 and reducing mutual interference between signals.

[0039] In this embodiment, please refer to Figure 4 and Figure 5 , Figure 4 yes Figure 1 A schematic diagram of the planar structure of the first circuit board in FIG. Figure 5 yes Figure 1 Schematic diagram of the planar structure of the second circuit board in. The first electromagnetic element 12 arranged on the first circuit board 10 can be a transformer, and the second electromagnetic element 22 arranged on the second circuit board 20 can be a filter. The difference between the transformer and the filter lies in the different winding methods of the coil loop wound around the magnetic core 13. The conductor patterns 152 on the transformer and the filter can be divided into multiple groups, but in the transformer, the number of conductor patterns 152 in each group is at least two, while in the filter, the number of conductor patterns 152 in each group is two.

[0040] In this embodiment, if Figure 4 and Figure 5As shown, the transformer includes two coil loops wound around the magnetic core 13, each coil loop has an input end and an output end; the filter also includes two coil loops wound around the magnetic core 13, each coil loop has an input end and an output end.

[0041] In this embodiment, the electrical connection between the second circuit board 20 and the first circuit board 10 actually means that the second electromagnetic element 22 disposed on the second circuit board 20 is electrically connected to the first electromagnetic element 12 disposed on the first circuit board 10 .

[0042] Specifically, in this embodiment, each transformer is electrically connected to a corresponding filter, and a transformer and a filter are electrically connected to form a group of electromagnetic components.

[0043] Among them, a coil loop in each transformer can be electrically connected to a coil loop in a corresponding filter. Specifically, the output end of the transformer can be electrically connected to the input end of the filter, thereby, the input end of the transformer, the coil in the transformer, the output end of the transformer, the input end of the filter, the coil in the filter and the output end of the filter can form a signal transmission line. A transformer and a filter are electrically connected to form two signal transmission lines, and the two signal transmission lines can form a signal channel.

[0044] It can be understood that in another embodiment, the first electromagnetic element 12 and the second electromagnetic element 22 can also be arranged in reverse, that is, the first electromagnetic element 12 can be a filter, and the second electromagnetic element 22 can be a transformer, and each transformer is electrically connected to a corresponding filter to form a group of electromagnetic components. The method for forming the electromagnetic component in this embodiment is the same as that in the previous embodiment, please refer to the description in the above embodiment, and it will not be repeated here.

[0045] Furthermore, at least two first electromagnetic components 12 arranged on the first circuit board 10 are insulated from each other, and second electromagnetic components 22 arranged on the same second circuit board 20 are insulated from each other, so that signals transmitted on different electromagnetic components are independent of each other, avoiding signal interference and crosstalk.

[0046] In this embodiment, the number of the second electromagnetic elements 22 arranged on each second circuit board 20 is equal, so that not only the size of each second circuit board 20 can be roughly the same, and thus the volume is more compact, but also the routing design of the second electromagnetic elements 22 can be facilitated.

[0047] Furthermore, if Figure 4 and Figure 5As shown, in this embodiment, a first connection terminal 24 is provided on each second circuit board 20, and a second connection terminal 14 is provided on the first circuit board 10. The first connection terminal 24 is electrically connected to the input end of the filter, and the second connection terminal 14 is electrically connected to the output end of the transformer. By electrically connecting the first connection terminal 24 and the second connection terminal 14, the first electromagnetic element 12 and the second electromagnetic element 22 can be electrically connected.

[0048] Optionally, in this embodiment, the first connection terminals 24 are disposed on a side of each second circuit board 20 that is perpendicular to the transmission line layer 15 and adjacent to the first circuit board 10 ; and the second connection terminals 14 are disposed on a main surface of the first circuit board 10 .

[0049] Specifically, the transmission line layer 15 on the second circuit board 20 is arranged on two opposite main surfaces of the substrate 11, and the first connection terminal 24 is arranged on the side surface of the second circuit board 20 connected between the two main surfaces. Among them, the main surface is the surface with the largest surface area on the substrate 11. The transmission line layer 15 is arranged on the two opposite main surfaces of the substrate 11, which can increase the wiring space and facilitate the design of the conductor pattern 152.

[0050] In this embodiment, the side surface of the second circuit board 20 is in contact with the main surface of the first circuit board 10, so that at least two second circuit boards 20 can be arranged on one first circuit board 10, reducing the volume of the connector 100. The first connection terminal 24 is arranged on the surface of the second circuit board 20 that contacts the first circuit board 10, and the second connection terminal 14 is arranged at the contact connection position between the first circuit board 10 and the second circuit board 20, so that when the second circuit board 20 contacts the first circuit board 10, the first connection terminal 24 and the second connection terminal 14 contact and align with each other, thereby facilitating the first connection terminal 24 and the second connection terminal 14 to be welded for electrical connection.

[0051] Optionally, the first connection terminal 24 is a pad disposed on the second circuit board 20, the second connection terminal 14 is a pad disposed on the first circuit board 10, and the first connection terminal 24 and the second connection terminal 14 are correspondingly welded. By setting both the first connection terminal 24 and the second connection terminal 14 as pads, the mutual contact surface of the first circuit board 10 and the second circuit board 20 can be made flat, thereby facilitating the connection of the first circuit board 10 and the second circuit board 20.

[0052] In another embodiment, the first connection terminal 24 may also be a conductive pin disposed on the second circuit board 20, and the second connection terminal 14 may be a conductive hole disposed on the first circuit board 10, and the conductive pin is correspondingly inserted into the conductive hole. By providing mutually matching conductive pins and conductive holes on the first circuit board 10 and the second circuit board 20, the contact area between the first connection terminal 24 and the second connection terminal 14 can be increased, thereby improving the electrical connection stability.

[0053] Furthermore, if Figure 5 As shown, in this embodiment, the second circuit board 20 is a rectangular plate, two filters are formed on the second circuit board 20, the second circuit board 20 has four side surfaces connected between two relative main surfaces, and the first connecting terminal 24 is arranged on the side of the second circuit board 20 adjacent to the input end and the output end of the coil loop.

[0054] Specifically, in this embodiment, a first connection terminal 24 is provided on the side with the shortest straight-line distance from the input end and the output end, and the first connection terminal 24 is electrically connected to the input end of the filter through a wiring formed on the transmission line layer 15. By providing the first connection terminal 24 on the side close to the input end, the length of the wiring can be reduced, thereby reducing the transmission loss of the signal.

[0055] Similarly, in this embodiment, the second connection terminal 14 can be arranged at a position of the first circuit board 10 adjacent to the input end of the coil loop to reduce the length of the wiring used to electrically connect the input end to the second connection terminal 14, thereby reducing signal transmission loss.

[0056] For further information, see Figure 6 and Figure 7 , Figure 6 is a schematic diagram of a three-dimensional structure of a connector in another embodiment of the present application, Figure 7 yes Figure 6 In this embodiment, the connector 200 includes a first circuit board 210, a second circuit board 220, and an adapter board 230. The adapter board 230 is disposed on a side of the first circuit board 210 away from the second circuit board 220 and is electrically connected to the first circuit board 210.

[0057] Among them, the structure of the first circuit board 210 in this embodiment is the same as the structure of the first circuit board 10 in the above embodiment, and the structure of the second circuit board 220 is the same as the structure of the second circuit board 20 in the above embodiment. Please refer to the description in the above embodiment and no further details will be given here.

[0058] Furthermore, a third connection terminal 212 is provided on a side of the first circuit board 210 facing away from the second circuit board 220, and a fourth connection terminal 232 is provided on a side of the adapter board 230 close to the first circuit board 210, and the third connection terminal 212 is electrically connected to the corresponding fourth connection terminal 232. In this embodiment, by providing the third connection terminal 212 and the fourth connection terminal 232 electrically connected to each other between the first circuit board 210 and the adapter board 230, it is convenient to electrically connect the first circuit board 210 with other components through the adapter board 230.

[0059] The third connection terminal 212 may be disposed on the first circuit board 210 near the input and output ends of the first electromagnetic element, thereby reducing the length of the wiring between the third connection terminal 212 and the input and output ends, thereby reducing the transmission loss of the line.

[0060] Furthermore, in this embodiment, the input end and the output end of the first electromagnetic element are both located on the surface of the first circuit board 210 close to the second circuit board 220, so as to facilitate the electrical connection between the first connection terminal and the input end or the output end. At this time, a conductive through hole can be opened on the first circuit board 210, and the third connection terminal 212 can be electrically connected to the input end or the output end by using the conductive through hole, so as to reduce the loss of signal transmission.

[0061] Optionally, the third connection terminal 212 is a pad disposed on the first circuit board 210, and the fourth connection terminal 232 is a pad disposed on the adapter board 230. By configuring the third connection terminal 212 and the fourth connection terminal 232 as pads, the contact surface between the first circuit board 210 and the adapter board 230 can be made flat, thereby facilitating the connection between the first circuit board 210 and the adapter board 230.

[0062] For further information, see Figure 6 and Figure 7 The connector 200 further includes a first conductive connector 240 disposed on the adapter board 230 , and the first conductive connector 240 is used to electrically connect the adapter board 230 to a docking connector (not shown in the figure).

[0063] Furthermore, the connector 200 also includes a second conductive connector 250, which is disposed on a side of the adapter board 230 away from the first circuit board 210, and is used to electrically connect the adapter board 230 to an external circuit board (not shown in the figure).

[0064] Among them, in this embodiment, the first conductive connector 240 is used to cooperate with the docking connector to receive the signal input of the docking connector. The input signal passes through the third connection terminal 212 and the fourth connection terminal 232 between the adapter board 230 and the first circuit board 210, enters the first circuit board 210, and is transmitted through a group of electromagnetic components to process the input signal. The processed signal is transmitted to the adapter board 230 again through the third connection terminal 212 and the fourth connection terminal 232, and is transmitted to the external circuit board through the second conductive connector 250. By setting the adapter board 230, on the one hand, it is convenient to electrically connect the first circuit board 210 with the first conductive connector 240, and to electrically connect the first circuit board 210 with the second conductive connector 250; on the other hand, it is convenient to redefine the third connection terminal 212 on the first circuit board 210, so that the connector 200 is adapted to the external circuit board.

[0065] Optionally, in this embodiment, the first conductive connector 240 and the second conductive connector 250 are respectively disposed on two sides of the adapter plate 230 along the arrangement direction of the second circuit board 220 .

[0066] Specifically, in this embodiment, Figure 6 and Figure 7 As shown, the two second circuit boards 220 are arranged side by side and spaced apart along the arrow direction shown in the figure. The middle area of ​​the adapter board 230 is used to set the fourth connection terminal 232 to electrically connect the adapter board 230 with the first circuit board 210. The first conductive connector 240 and the second conductive connector 250 are respectively arranged at opposite ends of the adapter board 230 along the arrow direction shown in the figure, so that the docking connector and the external circuit board are respectively located on different sides of the connector 200 to avoid interference between the docking connector and the external circuit board.
