Abstract
Description
Technical Field
[0001] This utility model relates to the field of multiple-choice circuit technology, specifically to a multiple-choice circuit device and its electronic equipment. Background Technology
[0002] Currently, in the field of electronic information technology, with the continuous miniaturization and increasing complexity of electronic devices, the requirements for circuit design are also becoming more and more stringent. In circuit design, the reliability and stability of signal transmission are crucial, especially in complex circuits. How to effectively achieve the transmission and connection of multiple signals while ensuring signal quality is a problem that urgently needs to be solved.
[0003] In traditional circuit design, a single path is typically used for signal transmission and connection. However, this design approach has several limitations. Firstly, when the signal transmission path is long or subject to interference, signal quality can easily degrade, leading to transmission errors or instability. Secondly, in some complex applications, multiple signals need to be transmitted simultaneously, and a single-path design is insufficient. Furthermore, traditional circuit design faces challenges related to space constraints and cost control. How to rationally arrange components within a limited circuit board space to achieve the transmission of multiple signals while reducing costs is a crucial issue that designers need to consider.
[0004] To address these issues, several improved design approaches have been proposed. For example, multilayer circuit board designs can be employed, increasing the number of layers to achieve more signal transmission paths. However, while this approach improves signal transmission capabilities, it also increases the complexity and cost of the circuit board. Furthermore, multilayer circuit board designs also face challenges related to signal integrity and electromagnetic interference.
[0005] Another approach is to use differential transmission technology, which improves signal immunity and transmission quality by transmitting signals with the same amplitude but opposite phase on two lines. However, differential transmission technology places high demands on circuit board routing, requiring equal length, equal width, and close proximity of traces; otherwise, signal quality will be affected. In practical applications, especially in space-constrained situations, achieving these conditions presents certain difficulties.
[0006] Furthermore, in certain specialized applications, such as those requiring the simultaneous transmission of multiple signals using only one signal, traditional design methods often fall short. For instance, some communication devices need to support multiple communication modes simultaneously, but only one mode is selected for communication. In such cases, traditional single-path or simple multi-path designs are insufficient, necessitating a more flexible and efficient circuit design approach. In summary, existing circuit design technologies still have numerous shortcomings in terms of signal transmission reliability, stability, space utilization, and cost control.
[0007] In view of the above, this application is hereby submitted. Utility Model Content

The terminal connection port is used for electrical connection with a terminal or a functional chip. The terminal connection port is connected to the coil output assembly through the loop assembly.

[0011] This utility model also discloses an electronic device, which includes a device body and a multi-select circuit device as described in any of the above.
[0012] In summary, the multi-choice circuit device employs multiple device coats, each outputting multiple loops to form various signal transmission paths.

The design of the signal transmission paths particularly emphasizes the importance of optimizing the routing connection method. By rationally selecting connection methods, such as direct surface layer connections, staggered spatial vias for layer replacement, or nearby vias for routing to other layers, interference during signal transmission can be effectively reduced, improving signal quality. This aims to solve the problems of single signal transmission paths, difficulty in guaranteeing signal quality, and cost and space constraints in existing complex circuit designs.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0026] This utility model discloses a multi-select circuit device, which includes: a terminal connection port, a loop assembly, and a coil output assembly. The terminal connection port is used for electrical connection with a terminal or a functional chip. The terminal connection port is connected to the coil output assembly through the loop assembly. The coil output assembly is used for electrical connection with different input modules and conversion chips.
[0027] The terminal connection port is used to receive signals from the same source or multiplexed signals from the terminal or functional chip. The coil output component includes multiple output ports, each of which is used to transmit signals from the same source or multiplexed signals to the corresponding input module or conversion chip.
[0028] Specifically, in this embodiment, the core of the multi-select circuit device lies in its unique structural design, which enables flexible signal transmission and efficient processing to meet the diverse signal connection needs of complex electronic systems, while optimizing circuit space layout and cost control. The device mainly includes a terminal connection port, a loop assembly, and a coil output assembly. The terminal connection port, as the signal entry point, electrically connects to external terminal devices or functional chips, and is responsible for receiving homologous or multiplexed signals from these devices. Homologous signals refer to signals with the same source, while multiplexed signals are multiple signals with different functions transmitted in the same physical channel. This design allows the device to adapt to different types of signal inputs, enhancing its versatility and applicability.
[0029] After the signal is received at the terminal connection port, it is transmitted through the loop assembly. The loop assembly plays a crucial role in this process, ensuring not only accurate signal transmission from the terminal connection port to the coil output component, but also guaranteeing signal integrity and stability during transmission through a carefully designed circuit layout. Specifically, the loop assembly employs an equal-length design and appropriate resistor configuration, effectively reducing signal distortion and delay during transmission. This optimized design is particularly important for high-speed signal transmission, significantly reducing signal interference and improving signal transmission quality and reliability, thereby ensuring stable operation of the device in various complex application scenarios.
[0030] Finally, the signal reaches the coil output component. The coil output component is the core innovation of this invention; it contains multiple output ports, each capable of electrical connection to different input modules or conversion chips. This multi-choice design gives the device extremely high flexibility, allowing it to selectively transmit homogeneous or multiplexed signals to corresponding input modules or conversion chips according to actual application requirements. For example, in some application scenarios, only one specific signal may need to be transmitted, while in others, multiple signals may need to be transmitted simultaneously. By rationally configuring the output ports of the coil output component, the device can easily achieve flexible signal switching and transmission, meeting diverse needs and greatly improving the flexibility and adaptability of circuit design.
[0031] In practical applications, the multi-select circuit device has demonstrated significant advantages. First, the versatility of the terminal connectors allows the device to receive various signal types, enhancing its versatility across different electronic systems. Second, the optimized design of the loop components effectively improves the quality and stability of signal transmission, reducing signal distortion and interference, which is particularly important for high-speed signal transmission. Finally, the multi-select design of the coil output component not only provides great flexibility but also allows for flexible signal switching and transmission according to specific needs, meeting diverse application scenarios. Furthermore, the device's design fully considers cost and space optimization. Through a compact circuit layout and efficient signal transmission paths, the device reduces circuit board area and cost while maintaining performance, making it particularly suitable for space-constrained electronic devices such as smartphones and tablets, effectively improving device integration and performance.
[0032] In this embodiment, the signals of the same origin can be USB 3.0 and USB 2.0 signals, HDMI 2.0 and HDMI 2.1 signals, etc., and the signals of multiplexing can be SATA signals and PCIe signals, etc. It should be noted that in other embodiments, other types of signals of the same origin or signals of multiplexing can also be used. There are no specific limitations here, but these solutions are all within the protection scope of this utility model.
[0033] Please see Figure 1 Preferably, the coating output component is a first output port and a second output port, both of which are electrically connected to the terminal connection port. The first output port is used to be electrically connected to the first input module or the first conversion chip, and the second output port is used to be electrically connected to the second input module or the second conversion chip.
[0034] Specifically, in this embodiment, the multi-select circuit device connects two devices with a total of three sets of output lines, of which... Figure 1The middle 'b' signal is the terminal signal, while 'a' and 'c' represent two different communication methods. Both paths require communication in the PCB design. Both output ports are electrically connected to the terminal connection port. The first output port is used for electrical connection to the first input module or the first conversion chip, while the second output port is used for electrical connection to the second input module or the second conversion chip. This multi-choice design concept gives the device extremely high flexibility, allowing it to selectively transmit homogeneous or multiplexed signals to the corresponding input modules or conversion chips according to actual application requirements. For example, in some application scenarios, it may only be necessary to transmit the signal to the first input module for processing, while in other scenarios, it may be necessary to transmit the signal to both the first and second input modules simultaneously to achieve more complex signal processing functions. By rationally configuring the output ports of the coil output component, the device can easily achieve flexible signal switching and transmission, meeting diverse needs and greatly improving the flexibility and adaptability of circuit design.
[0035] In actual use, two signals will not be output simultaneously; only one set of signals will be output at a time. Since CPU signals are defined, this is generally the mode of output. For example, USB signals are divided into USB 3.0 and USB 2.0 signals. These are signals from the same source but with different speeds. It's not that AB outputs USB and BC outputs HDMI. The difference is significant. It mainly depends on which type of signal the CPU supports. It can output multiplexed signals like SATA and PCIe; AB outputs SATA, and BC outputs PCIe, as long as the CPU supports it. However, AB and BC cannot be output simultaneously; the output is determined based on the actual usage.
[0036] Specifically, in this embodiment, the connection between the two device coats can occur in many ways, such as... Figures 2 to 4 As shown, signal quality requirements are met and connections are completed under different conditions. Figure 2 If signals a and c can be directly connected at the surface or separated by drilling holes to switch layers, then signal b only needs to drill holes nearby to access other layers. Figure 3 If signal a and signal b can be directly connected at the surface or separated by drilling holes to switch layers, then signal c only needs to drill holes nearby to access other layers. Figure 4 If only signal a can be directly connected at the surface without drilling or changing layers, then signals b and c need to be drilled and routed to other layers.
[0037] Please see Figure 5Preferably, the coating output component comprises a first output port, a second output port, and a third output port. The first output port, the second output port, and the third output port are all electrically connected to the terminal connection port. The first output port is used to electrically connect to a first input module or a first conversion chip, the second output port is used to electrically connect to a second input module or a second conversion chip, and the third output port is used to electrically connect to a third input module or a third conversion chip.
[0038] Specifically, in this embodiment, the multi-select circuit device is connected to three devices with a total of four sets of output lines, wherein... Figure 2 The middle 'b' signal is the terminal signal, while 'a', 'c', and 'd' represent three different communication methods. In PCB design, all three paths need to be connected for communication. All three output ports are electrically connected to the terminal connection port. The first output port is used for electrical connection to the first input module or the first conversion chip, the second output port is used for electrical connection to the second input module or the second conversion chip, and the third output port is used for electrical connection to the third input module or the third conversion chip. This multi-choice design concept gives the device extremely high flexibility, allowing it to selectively transmit homogeneous or multiplexed signals to the corresponding input modules or conversion chips according to actual application requirements. For example, in some application scenarios, it may only be necessary to transmit the signal to the first input module for processing, while in other scenarios, it may be necessary to transmit the signal to the first, second, and third input modules simultaneously to achieve more complex signal processing functions. By reasonably configuring the output ports of the colay output component, the device can easily achieve flexible signal switching and transmission, meeting diverse needs and greatly improving the flexibility and adaptability of circuit design. The specific implementation is similar to the case of connecting two colay devices, except that an additional colay device is added, which will not be elaborated further here. It should be noted that in other embodiments, other numbers of devices can be used as the colay, which is not specifically limited here, but these solutions are all within the protection scope of this utility model.
[0039] Specifically, in this embodiment, the connection of the three device coats can occur in many ways, such as... Figures 6 to 8 As shown, signal quality requirements are met and connections are completed under different conditions. Figure 6 Since signals a and d can be directly connected at the surface or separated by drilling holes to change layers, signals b and c need to be drilled nearby to access other layers. Figure 7 Since signals a and b can be directly connected at the surface or separated by drilling holes to switch layers, signals c and d need to be drilled nearby to access other layers. Figure 8 Only signal a can be directly connected at the surface layer, while signals b, c, and d need to be drilled nearby to access other layers.
[0040] In designing the signal transmission path, this device places particular emphasis on optimizing the routing and connection methods. By rationally selecting connection methods, such as direct surface layer connections, staggered via drilling for layer switching, or drilling vias to other layers nearby, interference during signal transmission can be effectively reduced, improving signal quality. Furthermore, this device proposes a unique device colay method, where the pads of one device are completely connected to the pads of another device, and only one type and size of device is used for colay, further enhancing signal quality and design flexibility. This design not only reduces costs but also optimizes the space utilization of the circuit board, making it particularly suitable for circuit board designs with fewer layers and limited space.

[0046] Specifically, in this embodiment, four sets of devices are coupled, outputting a total of five circuits; Figure 11 Interface 1 is connected to resistor 1 via signal a, and then to chip 2 via signal b, forming the ab signal path.
