Description

Technical Field

[0001] This application relates to the field of radio frequency signal transmission, specifically to a female connector assembly, a male connector assembly, and a display stand device. Background Technology

[0002] Some types of interfaces support both right-side-down and reverse-side-down insertion; the Type-C interface is one such type. The Type-C interface, short for USB Type-C interface, is a hardware interface standard for Universal Serial Bus (USB). Due to its small size, high efficiency, and versatility, the Type-C interface is widely used in modern electronic devices and is expected to gradually become the unified interface standard for electronic devices.

[0003] The Type-C interface includes 24 terminals, which can support high-speed data transmission, high-power charging, and audio and video transmission. However, there are no terminals for radio frequency (RF) signal transmission. One major reason for this is impedance mismatch: the Type-C interface has an impedance of 85 ohms, while the standard impedance for RF signals is 50 ohms. Impedance mismatch will greatly reduce the efficiency of RF signal transmission. Utility Model Content

[0042] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0043] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0044] The Type-C interface (or Type-C connector) includes a Type-C female connector and a Type-C male connector, which can be plugged into each other to achieve electrical connection.

[0045] Generally, a Type-C female connector includes 24 terminals, which are symmetrically distributed on side A and side B of the female connector. Figure 1 This is a schematic diagram of the terminal distribution as seen from the insertion direction of the female connector. There are 12 terminals A1 to A12 distributed on side A of the female connector, and 12 terminals B1 to B12 distributed on side B of the female connector. The details are explained below.

[0046] The 12 terminals A1 to A12 distributed on side A of the female connector are as follows: Terminal A1 is the ground terminal GND; Terminal A2 is the first type data transmission terminal TX1+, and Terminal A3 is the first type data transmission terminal TX1-. Terminals A2 and A3 form a pair of data transmission terminals, which can be used for high-speed data transmission under USB 3.0 and higher standards; Terminal A4 is the power terminal VBUS; Terminal A5 is the communication terminal CC1. For example, Terminal A5 can be used to detect cable connection and plug direction, negotiate power mode, and implement PD (Power Delivery) protocol and AM (Alternate Mode) communication, etc.; Terminal A6 is the second type data transmission terminal D+, and Terminal A7 is the second type data transmission terminal D-. Terminals A6 and A7 form a pair of data transmission terminals, which can be used for USB... The 2.0 standard data transmission terminal; terminal A8 is the auxiliary signal terminal SBU1, which can be used for low-speed signal transmission in modes such as AM (Alternate Mode); terminal A9 is the power supply terminal VBUS; terminal A10 is the first type data transmission terminal RX2-, terminal A11 is the first type data transmission terminal RX2+, terminals A10 and A11 form a pair of data transmission terminals, which can be high-speed data transmission terminals under USB 3.0 and higher standards; terminal A12 is the ground terminal GND.

[0047] The 12 terminals B1 to B12 distributed on side B of the female connector are as follows: Terminal B1 is the ground terminal GND; Terminal B2 is the first type data transmission terminal TX2+, and Terminal B3 is the first type data transmission terminal TX2-. Terminals B2 and B3 form a pair of data transmission terminals, which can be used for high-speed data transmission under USB 3.0 and higher standards; Terminal B4 is the power terminal VBUS; Terminal B5 is the communication terminal CC2. For example, Terminal B5 can be used to detect cable connection and plug direction, negotiate power mode, and implement PD (Power Delivery) protocol and AM (Alternate Mode) communication, etc.; Terminal B6 is the second type data transmission terminal D+, and Terminal B7 is the second type data transmission terminal D-. Terminals B6 and B7 form a pair of data transmission terminals, which can be used for USB... USB 2.0 standard data transmission terminal; terminal B8 is auxiliary signal terminal SBU2, which can be used for low-speed signal transmission in modes such as AM (Alternate Mode); terminal B9 is power terminal VBUS; terminal B10 is first-type data transmission terminal RX1-, terminal B11 is first-type data transmission terminal RX1+, terminals B10 and B11 form a pair of data transmission terminals, which can be high-speed data transmission terminals under USB 3.0 and higher standards; terminal B12 is ground terminal GND.

[0048] As can be seen, the 12 terminals A1 to A12 distributed on side A of the female connector correspond one-to-one with the 12 terminals B1 to B12 distributed on side B of the female connector, and are distributed in a centrally symmetrical manner, for example, with Figure 1 Taking the left and right directions as an example, there are 12 terminals A1 to A12 distributed from left to right on the A side of the female connector, and 12 terminals B1 to B12 distributed from right to left on the B side of the female connector. This provides the basis for the female connector to support both positive and negative insertion.

[0049] Generally, a Type-C male connector includes 24 terminals, which are symmetrically distributed on the A and B sides of the male connector. Figure 2 This is a schematic diagram of the terminal distribution as viewed from the insertion direction of the male connector. There are 12 terminals A1 to A12 on side A of the male connector, and 12 terminals B1 to B12 on side B of the male connector. The function of each terminal A1 to A12 on side A of the male connector can be found in the description of the 12 terminals A1 to A12 on side A of the female connector above. Similarly, the function of each terminal B1 to B12 on side B of the male connector can be found in the description of the 12 terminals B1 to B12 on side B of the female connector above. Specifically, terminal B5 of the male connector is the voltage connection terminal VCONN.

[0050] As can be seen, in Figure 1 The mother seat shown is Figure 2When the male and female connectors are inserted correctly, that is, when side A of the female connector contacts side A of the male connector to achieve electrical connection, and side B of the female connector contacts side B of the male connector to achieve electrical connection, the 12 terminals A1 to A12 on side A of the female connector and the 12 terminals A1 to A12 on side A of the male connector make contact one-to-one according to the same serial number to achieve electrical connection. Similarly, the 12 terminals B1 to B12 on side B of the female connector and the 12 terminals B1 to B12 on side B of the male connector make contact one-to-one according to the same serial number to achieve electrical connection. Connection; In the reverse insertion case, that is, the A side of the female connector is in contact with the B side of the male connector to achieve electrical connection, and the B side of the female connector is in contact with the A side of the male connector to achieve electrical connection. Thus, the 12 terminals A1 to A12 on the A side of the female connector and the 12 terminals B1 to B12 on the B side of the male connector are in contact one-to-one according to the same serial number to achieve electrical connection. It should be noted that in this article, "same serial number" refers to the same numerical serial number. Taking serial number 1 as an example, the A1 terminal of the female connector and the A1 terminal of the male connector have the same serial number; the B1 terminal of the female connector and the B1 terminal of the male connector have the same serial number; the A1 terminal of the female connector and the B1 terminal of the male connector have the same serial number; and the B1 terminal of the female connector and the A1 terminal of the male connector have the same serial number. Similarly, the A1 terminal of the female connector and the B1 terminal of the female connector have the same serial number, and the 1 terminal of the male connector and the B1 terminal of the female connector have the same serial number. The same applies to other serial numbers 2 to 12, which will not be elaborated here.

[0051] As explained above, the Type-C female and male connectors support both reversible insertion. Furthermore, as seen from the 12 terminals A1-A12 and B1-B12 mentioned above, the Type-C interface lacks terminals for radio frequency (RF) signal transmission. This means the Type-C interface does not support RF signal transmission. A primary reason for this is that the Type-C interface has an impedance of 85 ohms, while the standard impedance for RF signals is 50 ohms. This impedance mismatch significantly reduces the efficiency of RF signal transmission.

[0052] Please refer to Figure 3 and Figure 4 In some embodiments of this application, a female connector assembly 100 is disclosed. The female connector assembly 100 includes a female connector 110. The female connector 110 may include a tongue plate 111, a first terminal group 121, and a second terminal group 122, which will be described in detail below.

[0053] The tongue plate 111 has a first tongue plate surface 111a and a second tongue plate surface 111b that are parallel and opposite to each other. The tongue plate 111 includes a first insulating dielectric layer 112, a grounding layer 113, and a second insulating dielectric layer 114 that are sequentially distributed from the first tongue plate surface 111a to the second tongue plate surface 111b. In some embodiments, the thickness of the first insulating dielectric layer 112 and the second insulating dielectric layer 114 is approximately the same, that is, the distance from the first tongue plate surface 111a to the grounding layer 113 is approximately equal to the distance from the second tongue plate surface 111b to the grounding layer 113. The first insulating dielectric layer 112 and the second insulating dielectric layer 114 can both be made of insulating material, which is typically a non-metallic material (e.g., plastic). The materials of the first insulating dielectric layer 112 and the second insulating dielectric layer 114 can be the same or different. The grounding layer 113 can be made of conductive material, such as a metallic material.

[0054] A first terminal group 121 is disposed on the first tongue surface 111a of the tongue plate 111, and a second terminal group 122 is disposed on the second tongue surface 111b of the tongue plate 111. In some specific embodiments, the first terminal group 121 includes a plurality of first terminals 121a. In some examples, the number of first terminals 121a in the first terminal group 121 is greater than or equal to 3. The plurality of first terminals 121a are all disposed on the first tongue surface 111a and arranged along a first direction, which is perpendicular to the insertion direction of the female connector 110 and parallel to the first tongue surface 111a. In some specific embodiments, the second terminal group 122 includes a plurality of second terminals 122a. In some examples, the number of second terminals 122a in the second terminal group 122 is greater than or equal to 3. The plurality of second terminals 122a are all disposed on the second tongue surface 111b and arranged along a second direction, which is perpendicular to the insertion direction of the female connector 110 and parallel to the second tongue surface 111b. The first direction and the second direction are opposite.

[0055] In some embodiments, the number of first terminals 121a in the first terminal group 121 is equal to the number of second terminals 122a in the second terminal group 122. Furthermore, to enable the female connector assembly 100 to support reversible insertion, in some embodiments, the positions of the first terminals 121a in the first terminal group 121 arranged sequentially on the first tongue surface 111a along the first direction, and the positions of the second terminals 122a in the second terminal group 122 arranged sequentially on the second tongue surface 111b along the second direction, can be centrally symmetrical. In addition, the functions of each first terminal 121a arranged sequentially on the first tongue surface 111a in the first terminal group 121 and each second terminal 122a arranged sequentially on the second tongue surface 111b in the second terminal group 122 correspond one-to-one and can be identical. For example, the first terminal 121a numbered 1 in the first terminal group 121 arranged along the first tongue surface 111a and the second terminal 122a numbered 1 in the second tongue surface 111b in the second terminal group 122 correspond to each other and have the same function. The first terminal 121a of the first terminal group 121, arranged along the first direction on the first tongue surface 111a, and the second terminal 122a of the second terminal group 122, arranged along the second direction on the second tongue surface 111b, are corresponding and have the same function. The first terminal 121a of the first terminal group 121, arranged along the first direction on the first tongue surface 111a, and the second terminal 122a of the second terminal group 122, arranged along the second direction on the second tongue surface 111b, are corresponding and have the same function. The first terminal 121a of the first terminal group 121, arranged along the first direction on the first tongue surface 111a, and the second terminal 122a of the second terminal group 122, arranged along the second direction on the second tongue surface 111b, are corresponding and have the same function. Here, i is a positive number and is less than or equal to the number of first terminals 121a in the first terminal group 121 or the number of second terminals 122a in the second terminal group 122.

[0056] In some examples, the female connector assembly 100 is a Type-C compliant female connector assembly 100, and correspondingly, the female connector 110 is also a Type-C compliant female connector 110; in such examples, the number of first terminals 121a in the first terminal group 121 is 12, and the 12 first terminals 121a are arranged sequentially along the first direction on the first tongue plate surface 111a, and are numbered 1 to 12 respectively. These first terminals 121a numbered 1 to 12 can be as described above. Figure 1The 12 terminals A1 to A12 described herein; similarly, the number of second terminals 122a in the second terminal group 122 is 12, and the 12 second terminals 122a are arranged sequentially along the second direction on the second tongue plate surface 111b, and are numbered 1 to 12 respectively. These second terminals 122a numbered 1 to 12 can be those described above. Figure 2 The 12 terminals B1 to B12 are recorded.

[0057] In some embodiments, three adjacent first terminals 121a in the first terminal group 121 are used as the first radio frequency terminal group RF1. For the first radio frequency terminal group RF1: the first terminal 121a located in the middle (let's call it A) R2 The first terminal 121a (let's call it A) is used to transmit radio frequency signals and is located on both sides. R1 and A R3 ) are used for grounding respectively; for example Figure 5 An example of the first radio frequency terminal group RF1 is shown.

[0058] In the first radio frequency terminal group RF1, the middle first terminal A R2 As a signal line for transmitting radio frequency signals, the first terminals A on both sides R1 and A R3 As a ground wire, it is used for grounding and, together with grounding layer 113, forms a coplanar waveguide structure. By adjusting the impedance of the coplanar waveguide structure, it can be made suitable for transmitting radio frequency signals. The impedance of the coplanar waveguide structure can be adjusted to be suitable for transmitting radio frequency signals by adjusting the width of the signal line, the distance between the signal line and the two ground wires, the distance between the grounding layer and the plane containing the signal line / ground wire, and the dielectric constant of the medium between the grounding layer and the plane containing the signal line / ground wire. For example, the impedance of the coplanar waveguide structure can be adjusted to approximately 50 ohms or even precisely to 50 ohms. Therefore, please refer to... Figure 6 It can be achieved by adjusting the first terminal A R2 Width W along the first direction, first terminal A R2 Along the first direction and the first terminal A located on both sides R1 and A R3 The spacing L1 and L2, the distance H between the first tongue plate surface 111a and the ground layer 113, and the dielectric constant of the first insulating dielectric layer 112, ensure that the impedance of the female connector 110 for radio frequency signal transmission can match the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms. That is, in some embodiments, the first terminal A R2 Width W along the first direction, first terminal A R2 Along the first direction and the first terminal A located on both sides R1 and A R3The spacing L1 and L2, the distance H between the first tongue plate surface 111a and the ground layer 113, and the dielectric constant of the first insulating dielectric layer 112, enable the impedance of the female connector 110 for radio frequency signal transmission to match the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms.

[0059] The coplanar waveguide structure described above enables the transmission of radio frequency (RF) signals through the female connector 110. Furthermore, it can be seen that the coplanar waveguide structure offers a high degree of freedom in impedance adjustment, allowing for relatively easy achievement of the desired impedance through the adjustment of multiple parameters. This is particularly important when the female connector 110 is a Type-C interface, as the Type-C interface itself imposes certain range limitations on its parameters to comply with the Type-C standard, and its small size also restricts parameter adjustment. For example, some solutions also utilize a microstrip line structure to achieve RF signal transmission through the female connector 110. In a microstrip line structure, an RF signal is transmitted via a single terminal as a signal line. This terminal, along with the ground plane, forms the microstrip line structure. However, the impedance in a microstrip line structure can only be adjusted using three finite parameters: the width of the signal line, the distance between the ground plane and the signal line, and the dielectric constant of the medium between the ground plane and the signal line. Therefore, the impedance adjustment freedom is relatively low, making it difficult to achieve the desired impedance, especially for a Type-C interface.

[0060] Furthermore, the coplanar waveguide structure described above enables the transmission of radio frequency signals through the motherboard 110, since the first terminal A R2 The two adjacent sides are the first terminal A used for grounding. R1 and A R3 In other words, grounding wires are distributed on both sides of the signal line, which can effectively reduce signal crosstalk. This is especially important when the female connector 110 is of the Type-C standard, because the radio frequency signal itself is easily interfered with by external high-speed signals. Under the Type-C standard, there are 24 parallel transmission lines to transmit high-speed signals, and other signals inside will cause strong interference to the radio frequency signal. In contrast, in the scheme of implementing radio frequency signal transmission using microstrip line structure, the microstrip line structure is more sensitive to external interference and has poor signal isolation.

[0061] In some examples, the first radio frequency terminal group RF1 is configured as three first terminals 121a numbered 1 to 3 arranged along a first direction in the first terminal group 121. That is, these three adjacent first terminals 121a numbered 1 to 3 arranged along the first direction on the first tongue surface 111a of the first terminal group 121 are used as the first radio frequency terminal group RF1; for example, the first terminal A R1 The first terminal 121a, numbered 1, is arranged along the first direction on the first tongue plate surface 111a of the first terminal group 121. R2The first terminal 121a, numbered 2, is arranged along the first direction on the first tongue plate surface 111a of the first terminal group 121. The first terminal A R3 The first terminal 121a, numbered 3, is arranged along the first direction on the first tongue plate surface 111a of the first terminal group 121. In the example where the female connector 110 is of Type-C specification, the first terminal A... R1 This can be terminal A1 of the female connector under the Type-C specification, the first terminal A R2 This can be terminal A2 of the female connector under the Type-C specification, the first terminal A R3 This can be terminal A3 of the female connector under the Type-C specification, such as the one mentioned above. Figure 5 This is one example.

[0062] In some embodiments, three adjacent second terminals 122a in the second terminal group 122 are used as the second radio frequency terminal group RF2. For the second radio frequency terminal group RF2: the middle second terminal 122a (let's call it B) R2 The second terminal 122a (let's call it B) is used to transmit radio frequency signals and is located on both sides. R1 and B R3 These are used for grounding; for example, the ones mentioned above. Figure 5 An example of the second RF terminal group RF2 is shown.

[0063] In the second RF terminal group RF2, the middle second terminal B R2 As a signal line for transmitting radio frequency signals, the second terminals B on both sides R1 and B R3 As a ground wire, it is used for grounding and, together with grounding layer 113, forms a coplanar waveguide structure. By adjusting the impedance of the coplanar waveguide structure, it can be made suitable for transmitting radio frequency signals. The impedance of the coplanar waveguide structure can be adjusted to be suitable for transmitting radio frequency signals by adjusting the width of the signal line, the distance between the signal line and the two ground wires, the distance between the grounding layer and the plane containing the signal line / ground wire, and the dielectric constant of the medium between the grounding layer and the plane containing the signal line / ground wire. For example, the impedance of the coplanar waveguide structure can be adjusted to approximately 50 ohms or even precisely to 50 ohms. Therefore, please refer to... Figure 7 It can be adjusted by adjusting the second terminal B R2 Width W along the second direction, second terminal B R2 Along the second direction and the second terminal B located on both sides R1 and B R3 The spacing L1 and L2, the distance H between the second tongue plate surface 111b and the ground layer 113, and the dielectric constant of the second insulating dielectric layer 114, ensure that the impedance of the female connector 110 for radio frequency signal transmission can match the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms. That is, in some embodiments, the second terminal B R2Width W along the second direction, second terminal B R2 Along the second direction and the second terminal B located on both sides R1 and B R3 The spacing L1 and L2, the distance H between the second tongue plate surface 111b and the ground layer 113, and the dielectric constant of the second insulating dielectric layer 114, enable the impedance of the female connector 110 for radio frequency signal transmission to match the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms.

[0064] In some examples, the first terminal A R2 Width W along the first direction and second terminal B R2 The width W along the second direction is equal; in some examples, the first terminal A R2 Along the first direction and the first terminal A R1 The spacing L1 and the second terminal B R2 Along the second direction and the second terminal A R1 The spacing L1 is equal; in some examples, the first terminal A R2 Along the first direction and the first terminal A R3 The spacing L2 and the second terminal B R2 Along the second direction and the second terminal B R3 The spacing L2 is equal; in some examples, the distance H between the first tongue plate surface 111a and the ground layer 113, which is also the thickness H of the first insulating dielectric layer 112, is equal to the distance H between the second tongue plate surface 111b and the ground layer 113, which is also the thickness H of the second insulating dielectric layer 114; in some examples, the dielectric constant of the first insulating dielectric layer 112 is the same as the dielectric constant of the second insulating dielectric layer 114.

[0065] As described above, the scheme of transmitting radio frequency signals through the female connector 110 using a coplanar waveguide structure allows for relatively easy achievement of the desired impedance through adjustment of multiple parameters. This is especially important when the female connector 110 is Type-C compliant, as the Type-C interface itself imposes certain range limitations on various parameters to comply with the Type-C standard, and its small size also restricts parameter adjustment. Furthermore, in transmitting radio frequency signals through the female connector 110 using the aforementioned coplanar waveguide structure, due to the second terminal B... R2 The two adjacent sides are the second terminal B used for grounding. R1 and B R3 In other words, grounding wires are distributed on both sides of the signal line, which can effectively reduce signal crosstalk. This is especially important when the female connector 110 is of the Type-C standard, because the radio frequency signal itself is easily interfered by external high-speed signals. Under the Type-C standard, there are 24 parallel transmission lines to transmit high-speed signals, and other signals inside will cause strong interference to the radio frequency signal.

[0066] In some examples, the second RF terminal group RF2 is configured as three second terminals 122a numbered 1 to 3 arranged along the second direction in the second terminal group 122. That is, these three adjacent second terminals 122a numbered 1 to 3 arranged along the second direction on the second tongue surface 111b of the second terminal group 122 are used as the second RF terminal group RF2; for example, the second terminal B R1 The second terminal 122a, numbered 1, is arranged along the second direction on the second tongue plate surface 111b of the second terminal group 122. The second terminal B is... R2 The second terminal 122a, numbered 2, is arranged along the second direction on the second tongue plate surface 111b of the second terminal group 122. The second terminal B... R3 The second terminal 122a, numbered 3, is arranged along the second direction on the second tongue plate surface 111b of the second terminal group 122. In the example where the female connector 110 is of Type-C specification, the second terminal B... R1 This can be terminal B1 of the female connector under the Type-C specification, and the second terminal B. R2 This can be terminal B2 of the female connector under the Type-C specification, and the second terminal B. R3 This can be terminal B3 of the female connector under the Type-C specification, such as the one mentioned above. Figure 5 This is one example.

[0067] In some embodiments where three adjacent first terminals 121a in the first terminal group 121 are used as the first radio frequency terminal group RF1, and three adjacent second terminals 122a in the second terminal group 122 are used as the second radio frequency terminal group RF2, the sequence numbers of the three adjacent first terminals 121a used as the first radio frequency terminal group RF1 arranged along the second direction are the same as the sequence numbers of the three adjacent second terminals 122a used as the second radio frequency terminal group RF2; for example, first terminal A R1 With the second terminal B R1 The serial numbers are the same, and both can be numbered 1. The first terminal A R2 With the second terminal B R2 The serial numbers are the same, and both can be numbered 2. The first terminal A R3 With the second terminal B R3 The serial numbers are the same, and both can be numbered 3. This allows the female connector assembly 100 to support reversible insertion for radio frequency signal transmission from an electrical connection perspective. For example, in some examples where the female connector 110 is of Type-C specification, the first terminal A R1 This can be terminal A1 of the female connector under the Type-C specification, the first terminal A R2 This can be terminal A2 of the female connector under the Type-C specification, the first terminal A R3 This can be terminal A3 of the female connector under Type-C specification, and the second terminal B.R1 This can be terminal B1 of the female connector under the Type-C specification, and the second terminal B. R2 This can be terminal B2 of the female connector under the Type-C specification, and the second terminal B. R3 It can be terminal B3 of the female connector under the Type-C specification.

[0068] In some embodiments where three adjacent first terminals 121a in the first terminal group 121 are used as the first radio frequency terminal group RF1, and three adjacent second terminals 122a in the second terminal group 122 are used as the second radio frequency terminal group RF2, the first radio frequency terminal group RF1 and the second radio frequency terminal group RF2 can also cooperate to transmit radio frequency signals; for example, the same radio frequency signal is split into two radio frequency signals, namely the first radio frequency signal and the second radio frequency signal, by a device such as a power divider. The first terminal A in the first radio frequency terminal group RF1 R2 The second terminal B in the second RF terminal group RF2 is used to transmit the first RF signal. R2 Used to transmit a second radio frequency signal.

[0069] In some embodiments, please refer to Figure 8 The female connector 110 also includes an annular metal shell 123 for grounding, and a tongue plate 111 is suspended on the metal shell 123. The annular metal shell 123 provides signal shielding for the first terminal group 121 and the second terminal group 122 on the tongue plate 111, thus preventing or reducing the impact of external signals on the female connector 110 via the first terminal A. R2 Second terminal B R2 The transmitted radio frequency signal causes interference.

[0070] The above is some explanation of Mother Seat 110.

[0071] In some embodiments, please refer to Figure 9 The female connector assembly 100, based on the female connector 110, may further include a first circuit board 130, with the female connector 110 disposed on the first circuit board 130, for example, the female connector 110 being fixedly disposed on the first circuit board 130 by soldering; wherein, the first circuit board 130 may be a printed circuit board; it should be noted that... Figure 9 The dimensions of the first circuit board 130 shown are for illustrative purposes only; its actual size is determined based on design requirements, wiring, component layout, etc.

[0072] In some embodiments, please refer to Figure 10 The first circuit board 130 is provided with a first printed terminal group 131 and a second printed terminal group 132. The first printed terminal group 131 includes a plurality of first printed terminals 131a, and the second printed terminal group 132 includes a plurality of second printed terminals 132a.

[0073] In some embodiments, three adjacent first printed terminals 131a in the first printed terminal group 131 are used as the first printed radio frequency terminal group PRF1. For the first printed radio frequency terminal group PRF1: the three adjacent first printed terminals 131a are arranged along a third direction, and the first printed terminal 131a located in the middle (which may be referred to as PA) is the first printed terminal 131a located in the middle direction. R2 ) and the first terminal A located in the middle of the first radio frequency terminal group RF1 R2 Electrical connections for transmitting radio frequency signals are provided on both sides of the first printed terminal 131a (let's call it PA). R1 and PA R3 ) respectively connected to the first terminal A located on both sides of the first radio frequency terminal group RF1 R1 and A R3 Electrical connections, and respectively used for grounding; wherein the third direction is the same as the first direction; for example Figure 11 Here is an example.

[0074] As described above, when radio frequency signal transmission is achieved through the coplanar waveguide structure formed by the first radio frequency terminal group RF1 and the ground layer 113, adjustments can be made, such as to the first terminal A. R2 Width along the first direction, first terminal A R2 Along the first direction and the first terminal A located on both sides R1 and A R3 The spacing between the first tongue plate 111a and the ground layer 113, as well as the dielectric constant of the first insulating dielectric layer 112, ensure that the impedance of the female connector 110 for radio frequency signal transmission can match the radio frequency signal. However, since the customization freedom of the female connector 110 is far less than that of the first circuit board 130, for example, when the female connector 110 is of Type-C specification, the relevant parameters on the female connector 110 used to adjust the impedance of the coplanar waveguide structure, as mentioned above, will be limited. Furthermore, considering cost and other reasons, Type-C specification female connectors 110 are all mass-produced products rather than customized according to the above requirements, which makes the relevant physical dimensions of the female connector 110 fixed. Based on these considerations, the first circuit board 130 can be further introduced to adjust the impedance of the coplanar waveguide structure. Specifically, the first printed terminal PA... R2 It can be regarded as the first terminal A R2 Extension, first printed terminal PA R1 It can be regarded as the first terminal A R1 Extension, first printed terminal PA R3 It can be regarded as the first terminal A R3 An extension of that, therefore please refer to Figure 12 It can be achieved by adjusting the first printed terminal PA R2 Width W along the third direction, first printed terminal PA R2 Along the third direction and the first printed terminal PA located on both sidesR1 and PA R3 The spacing L1 and L2 is such that the impedance of the female connector 110 used for RF signal transmission can be matched to the RF signal, for example, approximately 50 ohms or even precisely 50 ohms. That is, in some embodiments, for the first printed RF terminal group PRF1: the first printed terminal PA located in the middle... R2 Width W along the third direction, first printed terminal PA R2 Along the third direction and the first printed terminal PA located on both sides R1 and PA R3 The spacing L1 and L2 allows the impedance of the female connector 110 for radio frequency signal transmission to be matched to the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms.

[0075] In some specific embodiments, for the first printed radio frequency terminal group PRF1: the first printed terminal PA located in the middle R2 The width W along the third direction is 0.1 mm to 0.75 mm, and the first printed terminal PA R2 Along the third direction and the first printed terminal PA located on both sides R1 and PA R3 The spacing between L1 and L2 is 0.01 mm to 0.25 mm, which is the first printed terminal PA. R2 Along the third direction and the first printed terminal PA R1 The spacing L1 is 0.01 mm to 0.25 mm, and the first printed terminal PA R2 Along the third direction and the first printed terminal PA R3 The spacing L2 is 0.01 mm to 0.25 mm.

[0076] The above is a brief description of the first printed radio frequency terminal block (PRF1).

[0077] In some embodiments, three adjacent second printed terminals 132a in the second printed terminal group 132 are used as the second printed radio frequency terminal group PRF2. For the second printed radio frequency terminal group PRF2: the three adjacent second printed terminals 132a are arranged along the fourth direction, and the second printed terminal 132a located in the middle (let's call it PB) R2 ) and the second terminal B located in the middle of the second RF terminal group RF2 R2 Electrical connections for transmitting radio frequency signals are provided on both sides of the second printed terminal 132a (let's call it PB). R1 and PB R3 ) respectively connected to the second terminals B located on both sides of the second RF terminal group RF2 R1 and B R3 Electrical connections, and respectively used for grounding; wherein the fourth direction is the same as the second direction; for example, as mentioned above. Figure 11 Here is an example.

[0078] As described above, when radio frequency signal transmission is achieved through the coplanar waveguide structure formed by the second radio frequency terminal group RF1 and the ground layer 113, adjustments can be made, such as to the second terminal B. R2 Width along the second direction, second terminal B R2 Along the second direction and the second terminal B located on both sides R1 and B R3 The spacing between the second tongue plate 111b and the ground layer 113, as well as the dielectric constant of the second insulating dielectric layer 114, ensure that the impedance of the female connector 110 for radio frequency signal transmission can match the radio frequency signal. However, since the customization freedom of the female connector 110 is far less than that of the first circuit board 130, for example, when the female connector 110 is of Type-C specification, the relevant parameters on the female connector 110 used to adjust the impedance of the coplanar waveguide structure, as mentioned above, will be limited. Furthermore, considering cost and other reasons, Type-C specification female connectors 110 are all mass-produced products rather than customized according to the above requirements, which makes the relevant physical dimensions of the female connector 110 fixed. Based on these considerations, the first circuit board 130 can be further introduced to adjust the impedance of the coplanar waveguide structure. Specifically, the second printed terminal PB R1 It can be regarded as the second terminal B R1 Extension, second printed terminal PB R2 It can be regarded as the second terminal B R2 Extension, second printed terminal PB R3 It can be regarded as the second terminal B R3 An extension of that, therefore please refer to Figure 13 This can be achieved by adjusting the second printed terminal PB. R2 Width W along the fourth direction, second printed terminal PB R2 Along the fourth direction and the second printed terminals PB located on both sides R1 and PB R3 The spacing L1 and L2 is such that the impedance of the female connector 110 used for RF signal transmission can be matched to the RF signal, for example, approximately 50 ohms or even precisely 50 ohms. That is, in some embodiments, for the second printed RF terminal group PRF2: the second printed terminal PB located in the middle... R2 Width W along the fourth direction, second printed terminal PB R2 Along the fourth direction and the second printed terminals PB located on both sides R1 and PB R3 The spacing L1 and L2 allows the impedance of the female connector 110 for radio frequency signal transmission to be matched to the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms.

[0079] In some specific embodiments, for the second printed radio frequency terminal group PRF2: the second printed terminal PB located in the middle. R2The width W along the fourth direction is 0.1 mm to 0.75 mm, and the second printed terminal PB R2 Along the fourth direction and the second printed terminals PB located on both sides R1 and PB R3 The spacing between L1 and L2 is 0.01 mm to 0.25 mm, which is the second printed terminal PB. R2 Along the fourth direction with the second printed terminal PB R1 The spacing L1 is 0.01 mm to 0.25 mm, and the second printed terminal PB R2 Along the fourth direction with the second printed terminal PB R3 The spacing L2 is 0.01 mm to 0.25 mm.

[0080] The above is some information about the second printed RF terminal block PRF2.

[0081] The description continues below of the first printed terminal group 131 and the second printed terminal group 132 of the first circuit board 130. In some examples, the first printed terminal group 131 of the first circuit board 130 is used for electrical connection with the first terminal group 121 of the female connector 110, so the number of first printed terminals 131a of the first printed terminal group 131 can be the same as the number of first terminals 121a of the first terminal group 121; similarly, the second printed terminal group 132 of the first circuit board 130 is used for electrical connection with the second terminal group 122 of the female connector 110, so the number of second printed terminals 132a of the second printed terminal group 132 can be the same as the number of second terminals 122a of the second terminal group 122.

[0082] In some specific embodiments, the plurality of first printed terminals 131a in the first printed terminal group 131 are arranged along a third direction; the plurality of first printed terminals 131a in the first printed terminal group 131 correspond one-to-one with and are electrically connected to the plurality of first terminals 121a in the first terminal group 121; for example, in an example where the female connector 110 is of Type-C specification, the first terminal group 121 includes 12 first terminals 121a, arranged sequentially along a first direction as first terminals A1 to A12, and correspondingly, the first printed terminal group 131 includes 12 first printed terminals 131a, arranged sequentially along a third direction as first printed terminals PA1 to PA12, and the first printed terminals PA1 to PA12 correspond one-to-one with the first terminals A1 to A12. Electrical connection; In some examples, the serial numbers of the three adjacent first printed terminals 131a of the first printed RF terminal group PRF1 arranged along a third direction are the same as the serial numbers of the three first terminals 121a in the first RF terminal group RF1 arranged along a first direction. For example, the serial numbers of the three first terminals 121a in the first RF terminal group RF1 arranged along the first direction are 1 to 3, that is, the three first terminals 121a in the first RF terminal group RF1 are first terminals A1 to A3, and the serial numbers of the three adjacent first printed terminals 131a in the first printed RF terminal group PRF1 arranged along a third direction are also 1 to 3, that is, the three adjacent first printed terminals 131a in the first printed RF terminal group PRF1 are PA1 to PA3.

[0083] In some specific embodiments, the plurality of second printed terminals 132a in the second printed terminal group 132 are arranged along the fourth direction; the plurality of second printed terminals 132a in the second printed terminal group 132 correspond one-to-one with and are electrically connected to the plurality of second terminals 122a in the second terminal group 122; for example, in an example where the female connector 110 is of Type-C specification, the second terminal group 122 includes 12 second terminals 122a, arranged sequentially along the second direction as second terminals B1 to B12, and correspondingly, the second printed terminal group 132 includes 12 second printed terminals 132a, arranged sequentially along the fourth direction as second printed terminals PB1 to PB12, and the second printed terminals PB1 to PB12 correspond one-to-one with the second terminals B1 to B12. Electrical connection; In some examples, the serial numbers of the three adjacent second printed terminals 132a of the second printed RF terminal group PRF2 arranged along the fourth direction are the same as the serial numbers of the three second terminals 122a of the second RF terminal group RF2 arranged along the second direction. For example, the serial numbers of the three second terminals 122a of the second RF terminal group RF2 arranged along the second direction are 1 to 3, that is, the three second terminals 122a of the second RF terminal group RF2 are the second terminals B1 to B3, and the serial numbers of the three adjacent second printed terminals 132a of the second printed RF terminal group PRF2 arranged along the fourth direction are also 1 to 3, that is, the three adjacent second printed terminals 132a of the second printed RF terminal group PRF2 are PB1 to PB3.

[0084] Understandably, in addition to the first printed terminal group 131 and the second printed terminal group 132, other terminals and / or components can be set on the first circuit board 130 according to actual functional requirements.

[0085] The above are some descriptions of the female connector assembly 100.

[0086] Please refer to Figure 14 In some embodiments of this application, a male connector assembly 200 is disclosed. For example, the male connector assembly 200 is used to cooperate with the female connector assembly 100 disclosed in any embodiment herein for the transmission of radio frequency signals.

[0087] In some embodiments, please refer to Figure 15 The male connector assembly 200 may include a male connector 210, which may include a base 211, a third terminal group 213 and a fourth terminal group 214, as described in detail below.

[0088] The base 211 has an inwardly facing, parallel and opposite first base surface 211a and a second base surface 211b.

[0089] A third terminal group 213 is disposed on a first base surface 211a, and a fourth terminal group 214 is disposed on a second base surface 211b. In some specific embodiments, the third terminal group 213 includes a plurality of third terminals 213a. In some examples, the number of third terminals 213a in the third terminal group 213 is greater than or equal to 3. The plurality of third terminals 213a are all disposed on the first base surface 211 and arranged along a fifth direction, which is perpendicular to the insertion direction of the male connector 210 and parallel to the first base surface 211a. In some specific embodiments, the fourth terminal group 214 includes a plurality of fourth terminals 214a. In some examples, the number of fourth terminals 214a in the fourth terminal group 214 is greater than or equal to 3. The plurality of fourth terminals 214a are all disposed on the second base surface 211b and arranged along a sixth direction, which is perpendicular to the insertion direction of the male connector 210 and parallel to the second base surface 211b. The fifth direction and the sixth direction are opposite.

[0090] In some embodiments, the number of third terminals 213a in the third terminal group 213 is equal to the number of fourth terminals 214a in the fourth terminal group 214. Furthermore, to enable the male connector assembly 200 to support reversible insertion, in some embodiments, the positions of the third terminals 213a in the third terminal group 213 arranged sequentially along the fifth direction on the first base surface 211a, and the positions of the fourth terminals 214a in the fourth terminal group 214 arranged sequentially along the sixth direction on the second base surface 211b, can be centrally symmetrical. In addition, the functions of each third terminal 213a arranged sequentially along the fifth direction on the first base surface 211a in the third terminal group 213 correspond one-to-one with the functions of each fourth terminal 214a arranged sequentially along the sixth direction on the second base surface 211b in the fourth terminal group 214, and can be identical. For example, the third terminal 213a numbered 1 in the third terminal group 213 arranged along the fifth direction on the first base surface 211a, and the fourth terminal 214a numbered 1 in the fourth terminal group 214 arranged along the sixth direction on the second base surface 211b, are corresponding and have the same function. The third terminal 213a of the three-terminal group 213, arranged along the fifth direction on the first base surface 211a, and the fourth terminal 214a of the fourth terminal group 214, arranged along the sixth direction on the second base surface 211b, are corresponding and have the same function. Similarly, the third terminal 213a of the three-terminal group 213, arranged along the fifth direction on the first base surface 211a, and the fourth terminal 214a of the fourth terminal group 214, arranged along the sixth direction on the second base surface 211b, are also corresponding and have the same function. Sub-terminals 214a and 214a are corresponding and have the same function. The third terminal 213a of the third terminal group 213 arranged along the fifth direction on the first base surface 211a and the fourth terminal 214a of the fourth terminal group 214 arranged along the sixth direction on the second base surface 211b are corresponding and have the same function. Here, i is a positive number and is less than or equal to the number of third terminals 213a in the third terminal group 213 or the number of fourth terminals 214a in the fourth terminal group 214.

[0091] In some examples, the male connector assembly 200 is a Type-C compliant male connector assembly 200, and correspondingly, the male connector 210 is also a Type-C compliant male connector 210; in such examples, the number of third terminals 213a in the third terminal group 213 is 12, and the 12 third terminals 213a are arranged sequentially along the fifth direction on the first base surface 211a, and are numbered 1 to 12 respectively. These third terminals 213a numbered 1 to 12 can be as described above. Figure 2The 12 terminals A1 to A12 described herein; similarly, the number of fourth terminals 214a in the fourth terminal group 214 is 12, and the 12 fourth terminals 214a are arranged sequentially along the sixth direction on the second base surface 211b, and are numbered 1 to 12 respectively. These fourth terminals 214a numbered 1 to 12 can be those described above. Figure 2 The 12 terminals B1 to B12 are recorded.

[0092] In some embodiments, three adjacent third terminals 213a in the third terminal group 213 are used as the third radio frequency terminal group RF3. For the third radio frequency terminal group RF3: the middle third terminal 213a (let's call it A) R2 The third terminal 213a (let's call it A) is used to transmit radio frequency signals and is located on both sides. R1 and A R3 ) are used for grounding, for example Figure 16 An example of the third RF terminal block RF3 is shown.

[0093] In the third RF terminal group RF3, the middle third terminal A R2 As a signal line for transmitting radio frequency signals, the third terminals A on both sides R1 and A R3 As a ground wire, it is used for grounding, forming a coplanar waveguide structure. By adjusting the impedance of the coplanar waveguide structure, it can be made suitable for transmitting radio frequency signals. The impedance of the coplanar waveguide structure can be adjusted to be suitable for transmitting radio frequency signals by adjusting the width of the signal line, the distance between the signal line and the two ground wires, etc., for example, adjusting the impedance of the coplanar waveguide structure to approximately 50 ohms or even precisely to 50 ohms. Therefore, the impedance can be adjusted by adjusting the third terminal A. R2 Width along the fifth direction, third terminal A R2 Along the fifth direction and the third terminal A located on both sides R1 and A R3 The spacing, etc., allows the impedance of the male connector 210 used for radio frequency signal transmission to match the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms. That is, in some embodiments, the third terminal A R2 Width along the fifth direction, third terminal A R2 Along the fifth direction and the third terminal A located on both sides R1 and A R3 The spacing allows the impedance of the male connector 210 for radio frequency signal transmission to be matched to the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms.

[0094] The scheme of transmitting radio frequency signals through the male connector 210 using a coplanar waveguide structure allows for relatively easy achievement of the desired impedance through adjustment of multiple parameters. This is especially important when the male connector 210 is a Type-C connector, as the Type-C interface itself imposes certain range limitations on various parameters to comply with the Type-C standard, and the small size of the interface also limits parameter adjustment. Furthermore, in implementing radio frequency signal transmission through the male connector 210 using the aforementioned coplanar waveguide structure, since the third terminal A... R2 The two adjacent sides are the third terminal A used for grounding. R1 and A R3 In other words, grounding wires are distributed on both sides of the signal line, which can effectively reduce signal crosstalk. This is especially important when the male connector 210 is a Type-C standard, because the radio frequency signal itself is easily interfered by external high-speed signals. Under the Type-C standard, there are 24 parallel transmission lines to transmit high-speed signals, and other signals inside it will cause strong interference to the radio frequency signal.

[0095] In some examples, the third RF terminal group RF3 is configured as three third terminals 213a numbered 1 to 3 arranged along the fifth direction in the third terminal group 213. That is, the three adjacent third terminals 213a numbered 1 to 3 arranged along the fifth direction on the first base surface 211a of the third terminal group 213 are used as the third RF terminal group RF3; for example, third terminal A R1 The third terminal 213a, numbered 1, is the third terminal 213a arranged along the fifth direction on the first base surface 211a of the third terminal group 213. The third terminal A... R2 The third terminal 213a, numbered 2, is the third terminal 213a arranged along the fifth direction on the first base surface 211a of the third terminal group 213. The third terminal A... R3 This refers to the third terminal 213a, numbered 3, arranged along the fifth direction on the first base surface 211a of the third terminal group 213. In the example where the male connector 210 is of Type-C specification, the third terminal A... R1 This can be terminal A1 of the male connector under the Type-C specification, and the third terminal A. R2 This can be terminal A2 of the male connector under the Type-C specification, and the third terminal A. R3 This can be terminal A3 of the male connector under the Type-C specification, such as the one mentioned above. Figure 16 Here is an example.

[0096] In some embodiments, three adjacent fourth terminals 214a in the fourth terminal group 214 are used as the fourth radio frequency terminal group RF4. For the fourth radio frequency terminal group RF4: the middle fourth terminal 214a (let's call it B) R2 The fourth terminal 214a (let's call it B) is used to transmit radio frequency signals and is located on both sides. R1and B R3 They are used for grounding respectively.

[0097] In the fourth RF terminal group RF4, the middle fourth terminal B R2 As a signal line for transmitting radio frequency signals, the fourth terminals B on both sides R1 and B R3 As a ground wire, it is used for grounding, forming a coplanar waveguide structure. By adjusting the impedance of the coplanar waveguide structure, it can be made suitable for transmitting radio frequency signals. The impedance of the coplanar waveguide structure can be adjusted to be suitable for transmitting radio frequency signals by adjusting the width of the signal line, the distance between the signal line and the two ground wires, etc., for example, adjusting the impedance of the coplanar waveguide structure to approximately 50 ohms or even precisely to 50 ohms. Therefore, the impedance can be adjusted by adjusting the fourth terminal B. R2 Width along the sixth direction, fourth terminal B R Along the sixth direction and the fourth terminal B located on both sides R1 and B R3 The spacing, etc., allows the impedance of the male connector 210 used for radio frequency signal transmission to match the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms. That is, in some embodiments, the fourth terminal B... R2 Width along the sixth direction, fourth terminal B R2 Along the sixth direction and the fourth terminal B located on both sides R1 and B R3 The spacing allows the impedance of the male connector 210 for radio frequency signal transmission to be matched to the radio frequency signal, for example, approximately 50 ohms or even precisely 50 ohms.

[0098] The scheme of transmitting radio frequency signals through the male connector 210 using a coplanar waveguide structure allows for relatively easy achievement of the desired impedance through adjustment of multiple parameters. This is especially important when the male connector 210 is a Type-C connector, as the Type-C interface itself imposes certain range limitations on various parameters to comply with the Type-C standard, and the small size of the interface also restricts parameter adjustment. Furthermore, in implementing radio frequency signal transmission through the male connector 210 using the aforementioned coplanar waveguide structure, due to the fourth terminal B... R2 The two adjacent sides are the fourth terminal B used for grounding. R1 and B R3 In other words, grounding wires are distributed on both sides of the signal line, which can effectively reduce signal crosstalk. This is especially important when the male connector 210 is a Type-C standard, because the radio frequency signal itself is easily interfered by external high-speed signals. Under the Type-C standard, there are 24 parallel transmission lines to transmit high-speed signals, and other signals inside it will cause strong interference to the radio frequency signal.

[0099] In some examples, the fourth RF terminal group RF4 is configured as three fourth terminals 214a numbered 1 to 3 arranged along the sixth direction in the fourth terminal group 214. That is, the three adjacent fourth terminals 214a numbered 1 to 3 arranged along the sixth direction on the second base surface 211b of the fourth terminal group 214 are used as the fourth RF terminal group RF4; for example, fourth terminal B R1 The fourth terminal 214a, numbered 1, is the fourth terminal 214a arranged along the sixth direction on the second base surface 211b of the fourth terminal group 214, and the fourth terminal B is the fourth terminal 214a. R2 The fourth terminal 214a, numbered 2, is the fourth terminal 214a arranged along the sixth direction on the second base surface 211b of the fourth terminal group 214, and the fourth terminal B is the fourth terminal 214a. R3 This refers to terminal 214a, numbered 3, which is the fourth terminal of the fourth terminal group 214 arranged along the sixth direction on the second base surface 211b. In the example where the male connector 210 is of Type-C specification, then the fourth terminal B... R1 This can be terminal B1 of the male connector under the Type-C specification, and the fourth terminal B. R2 This can be terminal B2 of the male connector under the Type-C specification, the fourth terminal B. R3 This can be terminal B3 of the male connector under the Type-C specification, such as the one mentioned above. Figure 16 Here is an example.

[0100] In some embodiments where three adjacent third terminals 213a in the third terminal group 213 are used as the third radio frequency terminal group RF3, and three adjacent fourth terminals 214a in the fourth terminal group 214 are used as the fourth radio frequency terminal group RF4, the sequence number of the three adjacent third terminals 213a used as the third radio frequency terminal group RF3 along the fifth direction is the same as the sequence number of the three adjacent fourth terminals 214a used as the fourth radio frequency terminal group RF4; for example, third terminal A R1 With the fourth terminal B R1 The serial numbers are the same, and both can be numbered 1. The third terminal A... R2 With the fourth terminal B R2 The serial numbers are the same, and both can be numbered 2. The third terminal A... R3 With the fourth terminal B R3 The serial numbers are the same, and both can be numbered 3. This allows the male connector assembly 200 to support reversible insertion for radio frequency signal transmission from an electrical connection perspective. For example, in some examples where the male connector 210 is of the Type-C specification, the third terminal A... R1 This can be terminal A1 of the male connector under the Type-C specification, and the third terminal A. R2 This can be terminal A2 of the male connector under the Type-C specification, and the third terminal A. R3 This can be terminal A3 and fourth terminal B of the male connector under the Type-C specification. R1This can be terminal B1 of the male connector under the Type-C specification, and the fourth terminal B. R2 This can be terminal B2 of the male connector under the Type-C specification, the fourth terminal B. R3 This can be terminal B3 of the male connector under the Type-C specification, such as the one mentioned above. Figure 16 Here is an example.

[0101] In some embodiments where three adjacent third terminals 213a in the third terminal group 213 are used as the third radio frequency terminal group RF3, and three adjacent fourth terminals 214a in the fourth terminal group 214 are used as the fourth radio frequency terminal group RF4, the third radio frequency terminal group RF3 and the fourth radio frequency terminal group RF4 can also cooperate to transmit radio frequency signals; for example, the same radio frequency signal is split into two radio frequency signals, namely the third radio frequency signal and the fourth radio frequency signal, by a device such as a power divider. The third terminal A in the third radio frequency terminal group RF3 R2 The fourth terminal B in the fourth RF terminal group RF4 is used to transmit the third RF signal. R2 Used to transmit a second radio frequency signal.

[0103] In some embodiments, please refer to Figure 17 The male connector assembly 200, based on the male connector 210, may further include a second circuit board 230, on which the male connector 210 is disposed. For example, the male connector 210 is fixedly disposed on the second circuit board 230 by soldering. The second circuit board 230 may be a printed circuit board. It should be noted that... Figure 17 The dimensions of the second circuit board 230 shown are for illustrative purposes only; its actual size is determined based on design requirements, wiring, component layout, etc.

[0104] In some embodiments, please refer to Figure 18 The second circuit board 230 is provided with a third printed terminal group 231 and a fourth printed terminal group 232. The third printed terminal group 231 includes multiple third printed terminals 231a, and the fourth printed terminal group 232 includes multiple fourth printed terminals 232a. Considering that the third printed terminal group 213 and the fourth printed terminal group 232 are respectively disposed on a parallel and opposite first base surface 211a and a second base surface 211b, in order to facilitate the electrical connection between the third printed terminal group 231 and the third terminal group 213, and the electrical connection between the fourth printed terminal group 232 and the fourth terminal group 214, the second circuit board 230 may have a first surface and a second surface. The third printed terminal group 231, i.e., multiple third printed terminals 231a, is disposed on the first surface, and the fourth printed terminal group 232, i.e., multiple fourth printed terminals 232a, is disposed on the second surface.

[0106] As described above, when radio frequency signal transmission is achieved through the coplanar waveguide structure formed by the third RF terminal group RF3, adjustments can be made, such as to the third terminal A. R2 Width along the fifth direction, third terminal A R2 Along the fifth direction and the third terminal A located on both sides R1 and A R3 The spacing, etc., ensure that the impedance of the male connector 210 used for RF signal transmission can match the RF signal; however, since the customization freedom of the male connector 110 is far less than that of the second circuit board 230, for example, when the male connector 210 is of Type-C specification, the relevant parameters on the male connector 210 used to adjust the impedance of the coplanar waveguide structure, as mentioned above, will be limited. Furthermore, considering cost and other reasons, Type-C male connectors 210 are mass-produced rather than customized according to the above requirements, which fixes the relevant physical dimensions of the male connector 210. Based on these considerations, a second circuit board 230 can be further introduced to adjust the impedance of the coplanar waveguide structure. Specifically, the third printed terminal PA...

The microphone is used to convert ambient sound into noise signals, the noise cancellation circuit is used to generate noise cancellation signals to cancel noise signals according to the noise signals, and the speaker is used to play noise cancellation signals for noise cancellation.

Through the antenna component, the display stand body 310 can conduct radio frequency communication with the headphone component 350 to transmit audio information, thereby enabling the display stand body 310 to replace a tablet computer or smartphone in the display stand scenario, greatly reducing costs.
