Description

TECHNICAL FIELD

[0001] The utility model relates to circuit board design technical field, specifically, it is related to a kind of circuit board structure for guaranteeing network port primary circuit through-flow. BACKGROUND

[0002] In the design of circuit board, the processing of network port (Ethernet interface) is crucial, which is directly related to the quality and efficiency of data transmission. Among them, impedance control is an important link in the design of circuit board, and is particularly critical for network port design. Impedance generally refers to the comprehensive effect of resistance, inductance and capacitance encountered by signal on transmission line. In network port communication, impedance is usually controlled at 100 ohms. Since signal propagates in the form of electromagnetic wave on transmission line, the consistency of impedance helps to reduce signal reflection and distortion, thereby ensuring the integrity and stability of signal.

[0003] However, since the length of network port primary signal line is usually short, the attenuation of signal in the transmission process will also be relatively small. If the impedance is required to be controlled at 100 ohms, the line width of signal line will be thin, resulting in poor through-flow effect, which will cause excessive voltage drop and heat generation when current passes through, and further affect the stability and reliability of the circuit.

[0004] The above defects need to be solved urgently. UTILITY MODEL CONTENT

[0005] In order to solve the problem of poor through-flow effect of existing network port primary signal line, the utility model provides a kind of circuit board structure for guaranteeing network port primary circuit through-flow.

[0006] The technical scheme of the utility model is as follows:

[0007] A kind of circuit board structure for guaranteeing network port primary circuit through-flow, including network port connector and transformer arranged on circuit board, the network port connector is connected with the transformer by line group, the line group includes two wires, and the line width of the wire is 10mil~20mil.

[0008] According to the utility model of the above scheme, the wire includes sequentially connected first connection section, intermediate section, second connection section, the first connection section is connected with the network port connector, and the second connection section is connected with the transformer.

[0009] According to the utility model of the above scheme, the spacing of two intermediate sections in the same line group is consistent.

[0010] According to the utility model of the above scheme, the spacing of two intermediate sections in the same line group is 10mil~20mil.

[0012] According to the utility model, the included angle between the corner section and the adjacent straight section is 120°.

[0013] According to the utility model, the width of the trace is 15 mil.

[0014] The utility model has the advantages that:

[0015] The circuit board structure ensures the current flow of the network port primary circuit without controlling the impedance of the circuit, thickens the width of the trace to ensure the current flow of the network port primary circuit, reduces the energy loss caused by impedance mismatch, and improves the current transmission efficiency. In addition, the width of the trace is 10 mil-20 mil, the wider trace can carry larger current, can ensure the stable transmission of current, and avoids problems such as overheating or damage of the circuit caused by excessive current. At the same time, thickening the trace reduces the voltage drop when the current passes through, reduces the energy loss of the current in the transmission process, thereby improving the energy utilization efficiency of the entire circuit. In addition, due to the thickening of the trace, the heat generated when the current passes through is more effectively dispersed, thereby reducing the risk of local overheating, and further ensuring the stability and reliability of the circuit.

[0020] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be described in further detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0021] In the circuit board design, the design of the network port (i.e. Ethernet interface) plays a pivotal role, which is directly related to the performance and efficiency of data transmission. Impedance control is an important link in the circuit board design, and is particularly crucial for network port design. Impedance generally refers to the comprehensive effect of resistance, inductance and capacitance encountered by the signal on the transmission line. In the network port communication mechanism, it is crucial to maintain the impedance standard of 100 ohms, because when the signal travels in the form of electromagnetic wave on the transmission line, the consistency of impedance helps to weaken the reflection and distortion of the signal, thereby ensuring the integrity and stability of the signal. However, since the length of the network port primary signal line is usually short, the loss in the signal transmission process is relatively small. If the impedance is controlled at 100 ohms, the line width of the signal line will be relatively thin, which will directly affect the current-carrying performance of the line. Thin line width may cause excessive voltage drop and heat when current passes through, thereby threatening the stability and reliability of the circuit.

[0022] As shown in Figure 1 To solve the above technical problems, the utility model provides a circuit board structure for ensuring the current-carrying of the network port primary line, which comprises a network port connector 2 and a transformer 3 arranged on a circuit board 1, and the network port connector 2 and the transformer 3 are connected through a line group. The line group comprises two wires 4, and the line width of the wire 4 is 10 mil-20 mil. In the prior art, the impedance is controlled at 100 ohms, and the line width of the network port primary line is below 6 mil. The utility model does not need to control the impedance of the line, and thickens the line width of the wire 4, which can ensure the current-carrying of the network port primary line, reduce the energy loss caused by impedance mismatch, and improve the current transmission efficiency.

[0023] Specifically, the line width of the wire 4 is 10 mil-20 mil, thereby thickening the line width of the wire 4. The wider wire 4 can carry more current, ensuring the stable transmission of the current and avoiding problems such as overheating or damage of the line caused by excessive current. At the same time, thickening the wire 4 reduces the voltage drop when the current passes through, reduces the energy loss of the current in the transmission process, and thereby improves the energy utilization efficiency of the entire circuit. In addition, since the wire 4 is thickened, the heat generated when the current passes through is more effectively dispersed, thereby reducing the risk of local overheating and ensuring the stability and reliability of the circuit.

[0024] In the embodiment, the line width of the trace 4 is 10-20 mils, and the line width of the trace 4 can be designed as any value in the interval of 10 mils, 12 mils, 13 mils, 14 mils, 15 mils, 16 mils, 17 mils, 18 mils, 19 mils, 20 mils, etc. In actual design, the line width of the trace 4 can be designed according to the application scenario, so as to improve the accuracy and customizability of the design of the circuit board 1, and enable the designer to optimize the line width of the trace 4 according to different application scenarios and performance requirements, so as to achieve the best signal transmission effect and cost benefit.

[0025] As shown in Figure 1 , Figure 2 In the embodiment, the trace 4 includes the first connection segment 41, the intermediate segment 42 and the second connection segment 43 connected in sequence, the first connection segment 41 is connected with the network port connector 2, and the second connection segment 43 is connected with the transformer 3. The segmented design makes the layout of the circuit board 1 more flexible, and the designer can freely adjust the length, shape and position of each segment of the trace 4 according to actual needs, so as to optimize the overall layout of the circuit board 1 and meet specific signal transmission requirements. In addition, the distance D between the two intermediate segments 42 in the same line group is kept consistent, that is, the two intermediate segments 42 in the same line group form a structure similar to a differential line, which can effectively offset external electromagnetic interference, improve the anti-interference ability of the signal, reduce distortion and attenuation of the signal in the transmission process, thereby improving the integrity of the signal and effectively reducing the influence of common mode noise.

[0026] As shown in Figure 2 In the embodiment, the distance D between the two intermediate segments 42 in the same line group is 10-20 mils, and the distance D between the two intermediate segments 42 in the same line group can be designed as any value in the interval of 10 mils, 12 mils, 13 mils, 14 mils, 15 mils, 16 mils, 17 mils, 18 mils, 19 mils, 20 mils, etc. In actual design, the distance D between the two intermediate segments 42 in the same line group can be designed according to the application scenario.

[0027] As shown in Figure 1 , Figure 2As shown, in the present embodiment, the middle section 42 of the wire 4 includes a plurality of straight sections 421 and corner sections 422 connected in sequence, and the wire 4 can make flexible turns through the corner sections 422 while maintaining a certain directionality, so as to adapt to the complex spatial layout requirements. At the same time, the combination of the straight sections 421 and the corner sections 422 enables the wire 4 to make more effective use of space, reduce unnecessary twists and turns, and improve the neatness and aesthetics of the overall layout. In addition, the included angle between the corner section 422 and the adjacent straight section 421 is obtuse, so that the wire 4 can make a smoother transition at the corner, reducing problems such as line compression, wear or signal attenuation that may be caused by sharp turns; and by using an obtuse corner, the wire 4 can more easily avoid other lines or components, reducing interference between them and improving the stability and reliability of the entire system.

[0028] In the present embodiment, the included angle between the corner section 422 and the adjacent straight section 421 is 120°, which can provide a relatively smooth transition interface, reducing the discontinuity of the signal when encountering a corner, so that the signal can propagate more smoothly at the corner, thereby reducing signal reflection, helping to maintain signal integrity and reducing signal distortion caused by corners. Of course, in actual design, the size of the included angle between the corner section 422 and the adjacent straight section 421 can be designed according to actual conditions.

[0029] In an alternative embodiment, the included angle between the corner section 422 and the adjacent straight section 421 is 130°, which can provide a relatively smooth transition interface, reducing the discontinuity of the signal when encountering a corner, so that the signal can propagate more smoothly at the corner, thereby reducing signal reflection, helping to maintain signal integrity and reducing signal distortion caused by corners. Of course, in actual design, the size of the included angle between the corner section 422 and the adjacent straight section 421 can be designed according to actual conditions.

[0030] In another alternative embodiment, the included angle between the corner section 422 and the adjacent straight section 421 is 150°, which can provide a relatively smooth transition interface, reducing the discontinuity of the signal when encountering a corner, so that the signal can propagate more smoothly at the corner, thereby reducing signal reflection, helping to maintain signal integrity and reducing signal distortion caused by corners. Of course, in actual design, the size of the included angle between the corner section 422 and the adjacent straight section 421 can be designed according to actual conditions.
