Description

Technical Field

[0001] This disclosure relates to the field of die-casting mold technology, and more specifically, to a circuit board and electronic equipment. Background Technology

[0002] With the rapid development of communication technology, especially the increasingly widespread application of 5G and higher frequency bands, higher requirements are being placed on the accurate testing of high-frequency signals. In related technologies, there is a significant distance between existing mid-to-high frequency antenna RF connectors and mid-to-high frequency main port RF connectors. This results in an excessively long connection path when connecting to the common terminal of the mid-to-high frequency signal, increasing signal transmission loss and affecting testing accuracy and efficiency. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a circuit board and an electronic device.

[0004] According to a first aspect of the present disclosure, a circuit board is provided, including a board body, a mid-to-high frequency antenna RF connector, a mid-to-high frequency main port RF connector, and a mid-to-high frequency signal common terminal, wherein the mid-to-high frequency antenna RF connector, the mid-to-high frequency main port RF connector, and the mid-to-high frequency signal common terminal are disposed on the same side of the board body. The mid-to-high frequency antenna RF connector and the mid-to-high frequency main port RF connector are respectively connected to the mid-to-high frequency signal common terminal, and the mid-to-high frequency antenna RF connector and the mid-to-high frequency main port RF connector are arranged adjacent to each other.

[0005] In some possible implementations, the distance between the mid-to-high frequency antenna RF connector and the mid-to-high frequency main port RF connector is 4.7mm-15mm. On the one hand, a suitable distance can effectively reduce the influence of electromagnetic coupling, making the signals transmitted by each RF connector relatively independent and reducing interference between signals; on the other hand, this distance range provides sufficient space for the installation of RF connectors and the arrangement of connecting cables, avoiding damage to RF connectors due to mutual squeezing or collision during installation or use.

[0006] In some possible implementations, the distance between the mid-to-high frequency antenna RF connector and the mid-to-high frequency signal common terminal is 2.7mm-30mm. On the one hand, a suitable distance can effectively reduce the influence of electromagnetic coupling, making the signals transmitted by each RF connector relatively independent and reducing interference between signals; on the other hand, this distance range provides sufficient space for the installation of RF connectors and the arrangement of connecting cables, avoiding damage to RF connectors due to mutual squeezing or collision during installation or use.

[0007] In some possible implementations, the circuit board further includes a first RF switch, a second RF switch, and a combiner. The mid-to-high frequency antenna RF connector is connected to the input terminal of the first RF switch, the mid-to-high frequency main port RF connector is connected to the input terminal of the second RF switch, the output terminal of the first RF switch is connected to the first input terminal of the combiner, the output terminal of the second RF switch is connected to the second input terminal of the combiner, and the output terminal of the combiner is connected to the mid-to-high frequency signal common terminal.

[0008] In some possible implementations, the radio frequency range of the medium-high frequency antenna RF connector is 1710MHz~2700MHz; The radio frequency range of the medium-high frequency main port RF connector is 1710MHz~2700MHz.

[0009] In some possible implementations, the circuit board further includes a low-frequency radio frequency connector disposed on the board body, and the low-frequency radio frequency connector is disposed on the side of the medium- and high-frequency signal common terminal away from the medium- and high-frequency antenna radio frequency connector.

[0010] In some possible implementations, the low-frequency radio frequency connector has a radio frequency range of 600MHz to 960MHz.

[0011] In some possible implementations, the mid-to-high frequency main port RF connector includes a first main port RF connector and a second main port RF connector, the first main port RF connector and the second main port RF connector are connected by a coaxial cable, and the second main port RF connector is disposed on the side of the first main port RF connector opposite to the mid-to-high frequency antenna RF connector.

[0012] In some possible implementations, the board body is provided with a signal common terminal arrangement area, and the mid-to-high frequency signal common terminal is arranged in the signal common terminal arrangement area and located on the side of the signal common terminal arrangement area close to the mid-to-high frequency antenna RF connector or the mid-to-high frequency main port RF connector.

[0013] According to a second aspect of the present disclosure, an electronic device is provided, including a circuit board as described above.

[0014] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: Through the above technical solution, this disclosure arranges the mid-to-high frequency antenna RF connector and the mid-to-high frequency main port RF connector close together, thereby reducing the distance between the mid-to-high frequency antenna RF connector and the mid-to-high frequency main port RF connector. This greatly shortens the path when they are connected to the common terminal of the mid-to-high frequency signal, reducing the attenuation and interference of the signal during transmission. This effectively reduces the loss of mid-to-high frequency signals during transmission, enabling the RF signal to be transmitted further and with stronger penetration. It also alleviates problems such as disconnection in weak signal areas, reduces signal attenuation and retransmission, and improves the download and latency performance of the 5G / millimeter wave band.

[0015] Furthermore, because the solution provided in this disclosure results in less loss during radio frequency transmission, the terminal does not need to increase its transmission power to compensate for the loss, thus achieving the goal of extending the phone's battery life.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, directional terms are used only for the convenience of describing the disclosure and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of the disclosure. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. In addition, the terms "first," "second," etc., are used to distinguish one element from another and do not have any sequential or importance.

[0021] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0022] After research, the following is true. Figure 2 In related technologies, there is a large distance between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30. As a result, when the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 are connected to the mid-to-high frequency signal common terminal 40, there is a large connection path between them and the mid-to-high frequency signal common terminal 40. The excessively long connection path will lead to problems such as signal distortion and attenuation, causing the signal received by the device to deviate from the actual signal, thereby affecting the accuracy and stability of signal transmission.

[0023] In view of this, such as Figure 1 As shown, according to a first aspect of the present disclosure, a circuit board 1 is provided, including a board body 10, a mid-to-high frequency antenna RF connector 20, a mid-to-high frequency main port RF connector 30, and a mid-to-high frequency signal common terminal 40. The mid-to-high frequency antenna RF connector 20, the mid-to-high frequency main port RF connector 30, and the mid-to-high frequency signal common terminal 40 are disposed on the same side of the board body 10. The mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 are respectively signal connected to the mid-to-high frequency signal common terminal 40, and the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 are disposed adjacent to each other.

[0024] Through the above technical solution, this disclosure arranges the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 close together, thereby reducing the distance between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30. This greatly shortens the path when they are connected to the mid-to-high frequency signal common terminal 40, reducing the attenuation and interference of the signal during transmission. This effectively reduces the loss of mid-to-high frequency signals during transmission, enabling the RF signal to be transmitted further and with stronger penetration. It also alleviates problems such as disconnection in weak signal areas, reduces signal attenuation and retransmission, and improves the download and latency performance of the 5G / millimeter wave band.

[0025] Furthermore, because the solution provided in this disclosure results in less loss during radio frequency transmission, the terminal does not need to increase its transmission power to compensate for the loss, thus achieving the goal of extending the phone's battery life.

[0026] In one exemplary embodiment provided in this disclosure, the aforementioned mid-to-high frequency antenna RF connector 20 can be a mid-to-high frequency antenna RF test socket, and the mid-to-high frequency main port RF connector 30 can be a mid-to-high frequency main port RF test socket.

[0027] like Figure 1 As shown, when two RF connectors are too close together, electromagnetic coupling may occur between them, leading to signal crosstalk and affecting the accuracy and stability of signal transmission. Furthermore, if the distance between RF connectors is too close (especially at high frequencies), mid-to-high frequency signals are highly sensitive to the impedance of the transmission line. Therefore, in some possible implementations, the distance S2 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 is 4.7mm-15mm. On the one hand, a suitable distance can effectively reduce the impact of this electromagnetic coupling, making the signals transmitted by each RF connector relatively independent and reducing interference between signals; on the other hand, this distance range provides sufficient space for the installation of RF connectors and the arrangement of connecting cables, avoiding damage to the RF connectors due to mutual squeezing or collision during installation or use.

[0028] In one exemplary embodiment provided in this disclosure, the distance S2 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 is 5.2 mm. At this distance, RF transmission loss and attenuation can be effectively reduced, enabling RF signals to transmit further and with stronger penetration.

[0029] Similarly, such as Figure 1 As shown, in some possible implementations, the distance L2 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency signal common terminal 40 is 2.7mm-30mm. On the one hand, a suitable distance can effectively reduce the influence of electromagnetic coupling, making the signals transmitted by each RF connector relatively independent and reducing interference between signals; on the other hand, this distance range provides sufficient space for the installation of RF connectors and the arrangement of connecting cables, avoiding damage to RF connectors due to mutual squeezing or collision during installation or use.

[0030] In one exemplary embodiment provided in this disclosure, the distance L2 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency signal common terminal 40 is 7.6 mm. At this distance, RF transmission loss and attenuation can be effectively reduced, enabling RF signals to transmit further and with stronger penetration.

[0031] For the aforementioned implementation where the distance S2 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 is 5.2 mm and the distance L2 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency signal common terminal 40 is 7.6 mm, the total length of the connection path between the mid-to-high frequency antenna RF connector 20, the mid-to-high frequency main port RF connector 30 and the mid-to-high frequency signal common terminal 40 is 12.8 mm.

[0032] In related technologies, it can be seen through measurement that the following methods are used: Figure 2 In the publicly disclosed scheme, when arranging the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30, the distance S1 between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 is 16.5mm, and the distance L1 between the mid-to-high frequency main port RF connector 30 and the mid-to-high frequency signal common terminal 40 is 9.0mm. Thus, the total length of the connection path between the mid-to-high frequency antenna RF connector 20, the mid-to-high frequency main port RF connector 30 and the mid-to-high frequency signal common terminal 40 is 25.5mm.

[0033] As can be seen, in the improved solution, the connection path between the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 and the mid-to-high frequency signal common terminal 40 is greatly shortened, the RF transmission loss is reduced, and the RF signal can be transmitted further and with stronger penetration, so as to alleviate the problem of disconnection in weak signal areas; secondly, it also reduces signal attenuation, reduces retransmission, and improves the download and latency performance of 5G / millimeter wave band.

[0034] Furthermore, because the solution provided in this disclosure results in less loss during radio frequency transmission, the terminal does not need to increase its transmission power to compensate for the loss, thus achieving the goal of extending the phone's battery life.

[0035] To achieve the connection between the aforementioned mid-to-high frequency antenna RF connector 20, mid-to-high frequency main port RF connector 30, and mid-to-high frequency signal common terminal 40, in one embodiment provided in this disclosure, the circuit board 1 may further include a first RF switch (not shown), a second RF switch (not shown), and a combiner (not shown). The mid-to-high frequency antenna RF connector 20 is connected to the input terminal of the first RF switch, the mid-to-high frequency main port RF connector 30 is connected to the input terminal of the second RF switch, the output terminal of the first RF switch is connected to the first input terminal of the combiner, the output terminal of the second RF switch is connected to the second input terminal of the combiner, and the output terminal of the combiner is connected to the mid-to-high frequency signal common terminal 40. The connection between the mid-to-high frequency antenna RF connector 20 and the input terminal of the first RF switch, and the connection between the mid-to-high frequency main port RF connector 30 and the input terminal of the second RF switch, allows for independent transmission of the mid-to-high frequency antenna and the mid-to-high frequency main port, as well as combined transmission of both, thereby meeting the diverse transmission requirements of the mid-to-high frequency signal system.

[0036] In one embodiment provided in this disclosure, the radio frequency range of the mid-to-high frequency antenna RF connector 20 is 1710MHz~2700MHz, and the radio frequency range of the mid-to-high frequency main port RF connector 30 is 1710MHz~2700MHz.

[0037] For the aforementioned implementation where the radio frequency range of the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 can be 1710MHz~2700MHz, the frequency band signals that the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30 can receive and transmit are such as B1 / B2 / B3 / B4 in the 5G / millimeter wave band.

[0038] In some possible implementations, the circuit board 1 may also include a low-frequency radio frequency connector 50, which is disposed on the board body 10 and is located on the side of the medium- and high-frequency signal common terminal 40 away from the medium- and high-frequency antenna radio frequency connector 20.

[0039] In some possible implementations, the radio frequency range of the low-frequency RF connector 50 can be 600MHz to 960MHz. Low-frequency signals have better penetration and coverage, making them suitable for communication needs in indoor or complex environments.

[0040] For the implementation of the low-frequency radio frequency connector 50 mentioned above, which has a radio frequency range of 600MHz to 960MHz, the frequency band signals that the low-frequency radio frequency connector 50 can receive and transmit are such as B5 / B8 / B12 / B13 of 4G / LTE.

[0041] In mid-to-high frequency antenna systems, each RF connector needs to be connected to the corresponding device or antenna. If the RF connector layout is unreasonable, it may lead to cable crossing and tangling, increasing the risk of signal interference and hindering equipment installation and debugging. Therefore, in one embodiment provided in this disclosure, the mid-to-high frequency main port RF connector 30 may include a first main port RF connector 31 and a second main port RF connector (not shown). The first main port RF connector 31 and the second main port RF connector are connected via a coaxial cable. The second main port RF connector is located on the side of the first main port RF connector 31 facing away from the mid-to-high frequency antenna RF connector 20. By positioning the second main port RF connector away from the mid-to-high frequency antenna RF connector 20, interference or interference from the mid-to-high frequency antenna RF connector 20 to the coaxial cable routing can be effectively avoided during the connection of the first main port RF connector 31 and the second main port RF connector via the coaxial cable, and the spatial layout of each connector can be effectively optimized.

[0042] In this disclosure, the first main port RF connector 31 and the second main port RF connector provided above can serve as backup RF connectors for each other. For example, in one embodiment provided in this disclosure, when a user covers one of the first main port RF connector 31 and the second main port RF connector using an electronic device, the signal transmitted by the covered RF connector is weakened. At this time, the other of the first main port RF connector 31 and the second main port RF connector can still continue to perform good signal transmission.

[0043] In some possible implementations, such as Figure 1 As shown, a signal common terminal arrangement area 60 is provided on the board body 10. The mid-to-high frequency signal common terminal 40 is arranged within the signal common terminal arrangement area 60 and is located on the side of the signal common terminal arrangement area 60 closest to the mid-to-high frequency antenna RF connector 20 or the mid-to-high frequency main port RF connector 30. In this way, by arranging the mid-to-high frequency signal common terminal 40 close to the high frequency antenna RF connector or close to the mid-to-high frequency main port RF connector 30, the total distance between the mid-to-high frequency signal common terminal 40 and the high frequency antenna RF connector or the high frequency main port RF connector can be further shortened, thereby reducing the loss of mid-to-high frequency signals during transmission and enabling the RF signal to be transmitted further and with stronger penetration.

[0044] It should be added that the circuit board 1 provided in this disclosure may also include a low-frequency signal common terminal 70, wherein the low-frequency signal common terminal 70 may also be disposed in the above-mentioned signal common terminal arrangement area 60. Furthermore, in order to facilitate the arrangement of the low-frequency signal common terminal 70 from interfering with the arrangement of the mid-to-high frequency signal common terminal 40, the low-frequency signal common terminal 70 may be disposed on the side of the signal common terminal arrangement area 60 away from the mid-to-high frequency antenna RF connector 20 or the mid-to-high frequency main port RF connector 30.

[0045] refer to Figure 1 and Figure 2 As shown in the comparison of the two figures, it can be seen that by adjusting the layout of the signal common terminal arrangement area 60, the area originally located in... Figure 2 The mid-to-high frequency signal common terminal 40 in the upper right corner of the signal common terminal arrangement area 60 is adjusted to... Figure 1 The signal common terminal arrangement area 60 is located in the upper left corner, thereby further shortening the distance between it and the mid-to-high frequency antenna RF connector 20 and the mid-to-high frequency main port RF connector 30, which are also located in the upper left corner of the signal common terminal arrangement area 60.

[0046] In addition, combined Figure 1 Figure 2 (by Figure 1 , Figure 2(As can be seen from the diagram orientation) the low-frequency RF connector 50 was originally located at the upper left of the board 10, and after the improvement it was moved to the lower left of the board 10. The low-frequency RF connector 50 was originally located at the upper left of the board 10, and after the improvement it was moved to the lower left of the board 10. The mid-to-high frequency main port RF connector 30 was originally located on the right side of the board 10, and after the improvement it was moved to the upper left of the board 10, closer to the mid-to-high frequency antenna RF connector 20.

[0047] According to a second aspect of the present disclosure, an electronic device is provided, including the circuit board 1 described above. This electronic device has all the beneficial effects of the circuit board 1, which will not be described further in this disclosure.

[0048] Furthermore, this disclosure does not limit the specific types of electronic devices mentioned above. For example, the electronic device may include, but is not limited to, mobile phones, tablets, computers, and other devices.

[0049] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0050] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0051] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
