Although Figure 1 The WiFi module 102 is shown, but it is understood that it is not a necessary component of the mobile terminal and can be omitted as needed without changing the essence of the utility model.

[0056] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.).

The GPU 1041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage media) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0058] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0059] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0060] User input unit 107 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as touch screen, can collect touch operations on or near the user (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0061] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides corresponding visual output on the display panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0062] Interface unit 108 serves as an interface through which at least one external device can connect to mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 108 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 100, or it may be used to transmit data between mobile terminal 100 and the external device.

[0063] The memory 109 can be used to store software programs and various data. The memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0064] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.

[0065] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0066] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0067] To facilitate understanding of the embodiments of this application, the communication network system on which the mobile terminal of this application is based is described below.

[0068] Please see Figure 2 , Figure 2 This application provides a communication network system architecture diagram. The communication network system is an LTE system based on the universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and the operator's IP services 204, which are connected in sequence.

[0069] Optionally, UE201 can be the aforementioned terminal 100, which will not be described in detail here.

[0070] E-UTRAN202 includes eNodeB2021 and other eNodeB2022s. Optionally, eNodeB2021 can connect to other eNodeB2022s via backhaul (e.g., X2 interface). eNodeB2021 connects to EPC203 and can provide UE201 with access to EPC203.

[0071] EPC203 may include an MME (Mobility Management Entity) 2031, an HSS (Home Subscriber Server) 2032, other MMEs 2033, an SGW (Serving Gateway) 2034, a PGW (Packet Data Network Gateway) 2035, and a PCRF (Policy and Charging Rules Function) 2036, which are policy and charging control decision points for service data flows and IP bearer resources. The policies may include, for example, Quality of Service (QoS) control policies, service access control policies, and charging policies. PCRF 2036 selects and provides available policy and charging control decisions for the Policy and Charging Enforcement Function Unit (not shown in the figure).

[0072] IP services 204 may include the Internet, intranet, IMS (IP Multimedia Subsystem), or other IP services.

[0073] Although the above description uses the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation.

[0074] Based on the aforementioned mobile terminal hardware structure and communication network system, embodiments of this application are proposed.

[0075] See Figure 3In the prior art, the circuit board 4 assembly includes a first circuit network and a second circuit network spaced apart, which are electrically connected to a first pad 4 and a second pad 5, respectively. To achieve the connection between the two circuit networks, a jumper connection structure is typically used, where the two ends of the jumper connection structure are connected to the first and second circuit networks respectively to form a current path. This connection method has certain drawbacks. Because the jumper structure itself is relatively simple in design and has a large resistance value, the equivalent resistance is high when current flows, resulting in low current transmission efficiency in the circuit. Simultaneously, the high resistance also leads to the generation of more heat in the circuit, further increasing the system's power consumption and potentially affecting the stability of circuit components. Ultimately, this method cannot meet the requirements of high current transmission, especially in applications requiring high power support, and may lead to performance degradation or overheating problems.

[0076] See Figure 4 To address the aforementioned problems, this embodiment describes the network connection structure based on a PCB circuit board 4 according to this utility model. This structure includes a circuit board 4, on which a first circuit network and a second circuit network are provided at intervals. A first connecting portion 61 and a third connecting portion 63 are disposed near the first circuit network. A second connecting portion 62 and a fourth connecting portion 64 are disposed near the second circuit network. The first connecting portion 61 is electrically connected to the first circuit network, the second connecting portion 62 is electrically connected to the first circuit network, the third connecting portion 63 is electrically connected to the second circuit network, and the fourth connecting portion 64 is electrically connected to the second circuit network.

[0077] The circuit board 4 also includes two shorting portions 7, which respectively short-circuit the first connecting portion 61 and the third connecting portion 63, and the second connecting portion 62 and the fourth connecting portion 64. These two shorting portions 7 form a parallel structure, reducing the equivalent resistance in the circuit and effectively solving the problem that existing jumper connection structures cannot meet high current requirements.

[0078] In one specific implementation of this embodiment, the circuit board 4 includes a first pad 4 and a second pad 5. The first pad 4 is divided into a first connection portion 61 and a third connection portion 63, and the second pad 5 is divided into a second connection portion 62 and a fourth connection portion 64. That is, without increasing the PCB area, the circuit connection area is rationally allocated by cutting the pads. Two shorting portions 7 are respectively connected to the two cut pads, thereby forming a short-circuit parallel structure between the first circuit network and the second circuit network. This effectively reduces the equivalent resistance in the circuit, improves current transmission capability, and optimizes circuit performance and stability.

[0079] Furthermore, the circuit board 4 is a multilayer circuit board 4, with each connection portion located on the uppermost or lowermost layer of the circuit board 4. The first circuit network and the second circuit network are located in the middle layer of the circuit board 4. The first connection portion 61 and the second connection portion 62 are electrically connected to the first circuit network through conductive vias, respectively. The third connection portion 63 and the fourth connection portion 64 are electrically connected to the second circuit network through conductive vias, respectively.

[0080] Since the first circuit network and the second circuit network are respectively connected to the first connecting part 61, the second connecting part 62, the third connecting part 63, and the fourth connecting part 64 through conductive vias, the specific connection points of the first circuit network and the second circuit network with respect to these connecting parts can be flexibly adjusted. In this way, a parallel jumper structure can be realized without changing the wiring of the uppermost circuit board 4, thereby reducing the equivalent resistance in the circuit.

[0081] Furthermore, the distance between the first connection portion 61 and the first circuit network is less than the distance between the first connection portion 61 and the second circuit network, ensuring that the first circuit network can be connected to the first shorting portion 7 with lower resistance, thereby optimizing the current transmission path. The distance between the third connection portion 63 and the first circuit network is less than the distance between the third connection portion 63 and the second circuit network, ensuring a better connection path between the first circuit network and the first shorting portion 7, and improving current transmission efficiency.

[0082] The distance between the second connecting part 62 and the first circuit network is greater than the distance between the second connecting part 62 and the second circuit network, so that the second shorting part 7 mainly functions to connect the second circuit network, reducing the influence of the first circuit network. The distance between the fourth connecting part 64 and the first circuit network is greater than the distance between the fourth connecting part 64 and the second circuit network, making it easier for the second shorting part 7 to connect to the second circuit network, ensuring the rationality and stability of the circuit connection.

[0083] Furthermore, the various connecting parts are arranged symmetrically on the circuit board 4. This makes the circuit structure more regular, facilitates processing and manufacturing, and improves product consistency and reliability.

[0084] See Figure 4 In one specific embodiment of this invention, the first connecting portion 61 and the second connecting portion 62 are disposed opposite to each other. The third connecting portion 63 and the fourth connecting portion 64 are disposed opposite to each other.

[0085] The distance between the first connecting portion 61 and the third connecting portion 63 is smaller than the distance between the first connecting portion 61 and the second connecting portion 62;

[0086] The distance between the first connecting part 61 and the third connecting part 63 is smaller than the distance between the third connecting part 63 and the fourth connecting part 64.

[0087] See Figure 5 In another specific embodiment of this invention, the first connecting portion 61 and the fourth connecting portion 64 are disposed opposite to each other. The third connecting portion 63 and the second connecting portion 62 are disposed opposite to each other.

[0088] The distance between the first connecting part 61 and the third connecting part 63 is smaller than the distance between the first connecting part 61 and the fourth connecting part 64;

[0089] The distance between the first connecting part 61 and the third connecting part 63 is smaller than the distance between the third connecting part 63 and the second connecting part 62.

[0090] Based on the actual wiring configuration of the four components on the circuit board, adjust the connection positions of the first circuit network with the first connection portion 61 and the second connection portion 62, as well as the positions of the second circuit network with the third connection portion 63 and the fourth connection portion 64. This better matches the actual connection requirements of the circuit, helps optimize the circuit layout, and ensures connection effectiveness and current transmission stability.

[0091] When the first shorting portion 7 and the third shorting portion 7 are formed by cutting the first pad 4, and the second shorting portion 7 and the fourth shorting portion 7 are formed by cutting the second pad 5, the cutting gap is designed to be small when cutting the first pad 4 and the second pad 5, so that the welding material can fill the cutting gap when welding the first connecting portion 61 and the third connecting portion 63. This maximizes the cross-sectional area of ​​the welding material. According to the factors affecting resistance, when the length and material of the resistor are the same, the larger its cross-sectional area, the smaller its resistance. In this way, the welding material is welded between the first circuit network and the second circuit network, forming a parallel jumper connection structure. This structure not only effectively reduces the equivalent resistance of the circuit but also saves material costs, while improving current transmission capability and optimizing the stability and performance of the circuit.

[0092] For further details, please refer to [link / reference]. Figure 6 In one specific embodiment of this invention, both the first shorting portion 7 and the second shorting portion 7 are formed by welding with welding material. The first connecting portion 61, the third connecting portion 63, the second connecting portion, and the fourth connecting portion 64 are respectively shorted by the welding material.

[0093] Furthermore, the first shorting portion 7 and the second shorting portion 7 are two terminals of the same electronic device;

[0094] The first terminal short-circuites the first connecting part 61 and the third connecting part 63, and the second terminal short-circuites the second connecting part 62 and the fourth connecting part 64.

[0095] Furthermore, the electronic device includes at least one of the following: a resistive element, a capacitive element, and an inductive element.

[0096] Specifically, see Figure 7 In another specific embodiment of this invention, the two shorting portions 7 of the circuit board 4 assembly are respectively the two terminals of the resistor element. One of the two terminals is shorted to the first connecting portion 61 and the third connecting portion 63, and the other is shorted to the second connecting portion 62 and the fourth connecting portion 64.

[0097] Specifically, the terminals of the resistive element are generally made of a metal material with good conductivity, which has a small resistance value, further reducing the equivalent resistance of the two short-circuit parts 7, thus ensuring smooth current flow and circuit stability.

[0098] Meanwhile, because the material cost of resistive elements is low and they can meet the electrical connection requirements of this embodiment, the resistive element can be used as a shorting part 7 and can also stabilize the current transmission in the circuit through its conductivity without increasing costs. This design makes the circuit structure simpler and more economical, while improving the stability and performance of the circuit.

[0099] Furthermore, the cutting interval between the first pad 4 and the second pad 5 is related to the model of the resistor element. Specifically, when the resistor element is a 0402 model, the cutting interval between the first pad 4 and the second pad 5 is 0.07mm-0.09mm.

[0100] Preferably, when the resistor element is a 0402 type, the cutting distance between the first pad 4 and the second pad 5 is 0.08mm.

[0101] Alternatively, the two shorting portions 7 may be two terminals of a capacitor element. One of the two terminals may be shorted to the first connecting portion 61 and the third connecting portion 63, and the other may be shorted to the second connecting portion 62 and the fourth connecting portion 64.

[0102] In short-circuit applications, the capacitor terminals serve as shorting parts 7, effectively suppressing high-frequency noise or pulse signals in the circuit and improving circuit stability. Compared to resistors, capacitors have frequency selectivity and can effectively isolate or balance high-frequency signals in the circuit through their impedance characteristics, making them particularly suitable for signal filtering or voltage regulation.

[0103] Alternatively, the two shorting portions 7 are the two terminals of the inductor;

[0104] One of the two terminals is short-circuited to the first connecting part 61 and the third connecting part 63, and the other is short-circuited to the second connecting part 62 and the fourth connecting part 64.

[0105] When the two shorting portions 7 are respectively the two terminals of the inductor, they can generate a back electromotive force when the current changes, thereby limiting the rapid change of current, especially in circuits used to reduce current fluctuations or smooth power transmission. This can enhance the current filtering effect of the circuit, making it particularly suitable for power management or power regulation circuits.

[0106] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
