[0052] The technical solutions of the embodiments of this application 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 application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0053] According to the first aspect of this application, see Figures 1 to 7 This application provides a signal transmission harness, including a first signal transmission component 1 and a second signal transmission component 2. The first signal transmission component 1 includes a coaxial cable 11, and the second signal transmission component 2 is connected to the coaxial cable 11. At least a portion of the second signal transmission component 2 is a flexible structure.

[0054] It is understandable that by using the coaxial cable 11 to transmit signals, the signal transmission loss of the signal transmission harness is reduced, thereby improving the signal transmission performance of the signal transmission harness. Simultaneously, signal transmission is achieved by using the second signal transmission component 2 in conjunction with the coaxial cable 11, and at least a portion of the second signal transmission component 2 is configured as a flexible structure. This flexible structure possesses bending resistance, improving the bending performance of the signal transmission harness. In other words, this application improves both the signal transmission performance and bending performance of the signal transmission harness by utilizing the coaxial cable 11 and the second signal transmission component 2, which has at least a flexible structure.

[0055] In some examples, the signal transmission harness can be applied to a laptop computer, with coaxial cable 11 connecting the laptop computer’s motherboard and a second signal transmission component 2, which in turn connects to the laptop computer’s screen, and the flexible structure is positioned in a location where it is frequently bent.

[0056] Since the motherboard of a laptop is a strong source of interference, placing the coaxial cable 11 on the motherboard can avoid screen flickering or display abnormalities caused by large signal transmission loss by utilizing the stable signal transmission and low loss characteristics of the coaxial cable 11.

[0057] The flexible structure can still transmit signals normally when bent and after multiple bends, so the laptop will not have problems such as broken signal transmission harness or abnormal signal transmission after being opened and closed many times.

[0058] It should be noted that this example is only used to illustrate the concept of a laptop computer and does not limit the signal transmission harness of this application to only be used in laptop computers.

[0059] In some examples, the second signal transmission component 2 is, for example, a flexible printed circuit board.

[0060] In some embodiments, see Figure 3 The second signal transmission component 2 includes at least two signal transmission parts 21 connected in sequence, and at least part of the signal transmission parts 21 is a flexible structure.

[0061] It is understandable that signal transmission is performed by using the second signal transmission component 2 and the coaxial cable 11 together, and at least part of the signal transmission part 21 is set as a flexible structure. The flexible signal transmission part 21 has the characteristic of being resistant to bending, which improves the bending performance of the signal transmission harness.

[0062] In some examples, all signal transmission units 21 may be flexible structures, or only some signal transmission units 21 may be flexible structures.

[0063] In some embodiments, see Figure 3 At least two signal transmission units 21 include a first flexible part 211, which is disposed at the connection between the second signal transmission component 2 and the coaxial line 11.

[0064] It is understandable that the first flexible part 211 has excellent bending performance. Using the first flexible part 211 as at least a part of the second signal transmission component 2 improves the bending performance of the second signal transmission component 2.

[0065] The connection between the coaxial cable 11 and the second signal transmission component 2 is prone to bending. By placing the first flexible part 211 at the connection between the second signal transmission component 2 and the coaxial cable 11, the bending reliability between the coaxial cable 11 and the second signal transmission component 2 is improved, and the connection stability between the coaxial cable 11 and the second signal transmission component 2 is improved.

[0066] In some examples, "the first flexible part 211 is located at the connection between the second signal transmission component 2 and the coaxial line 11" means that the connection between the second signal transmission component 2 and the coaxial line 11 is adjacent to the first flexible part 211. "The first flexible part 211 is located at the connection between the second signal transmission component 2 and the coaxial line 11" can also mean that the connection between the second signal transmission component 2 and the coaxial line 11 is adjacent to the first flexible part 211 but at a certain distance.

[0067] In some embodiments, see Figure 3 At least two signal transmission units 21 include a connection unit 212 connected to the first flexible unit 211.

[0068] It is understood that the connecting part 212 is mainly used to connect the coaxial line 11, and the first flexible part 211 can be disposed between the coaxial line 11 and the connecting part 212, or the connecting part 212 can be disposed between the first flexible part 211 and the coaxial line 11.

[0069] Specifically, the first flexible part 211 is adjacent to the connecting part 212.

[0070] It is understandable that the direct connection between the first flexible part 211 and the connecting part 212 can improve the bending performance at the connecting part 212.

[0071] Specifically, the first flexible part 211 and the connecting part 212 are spaced apart.

[0072] Understandably, the first flexible portion 211 can improve the bending performance of the second signal transmission component 2. The first flexible portion 211 and the connecting portion 212 are spaced apart so that when the bending position is spaced apart from the connecting portion 212, the first flexible portion 211 is exactly at the bending position.

[0073] In other words, the first flexible part 211 can be directly connected to the connecting part 212, or it can be spaced apart from the connecting part 212. The specific location can be determined according to the actual bending position of the electronic device to which the signal transmission harness is applied.

[0074] In some embodiments, see Figure 3 At least two signal transmission units 21 include a second flexible unit 213, and the first flexible unit 211 and the second flexible unit 213 are arranged at intervals.

[0075] It is understandable that both the first flexible part 211 and the second flexible part 213 have excellent bending performance, which can improve the bending performance of the second signal transmission component 2.

[0076] By spacing the first flexible part 211 and the second flexible part 213, the bending performance of the second signal transmission component 2 at different locations is improved, making the signal transmission harness suitable for situations requiring multiple bends.

[0077] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The signal transmission harness includes a first terminal block 3, which is connected to the end of the second signal transmission assembly 2 away from the coaxial line 11.

[0078] It is understandable that the first terminal 3 can be used to connect to electronic equipment so as to facilitate the connection between the second signal transmission component 2 and the electronic equipment.

[0079] In some embodiments, the second flexible portion 213 is disposed adjacent to the first terminal block 3.

[0080] It is understandable that by placing the second flexible part 213 adjacent to the first terminal 3, the bending performance at the first terminal 3 can be improved.

[0081] It is understandable that when the first terminal 3 is connected to an electronic device, bending may easily occur at the first terminal 3. Therefore, the second flexible part 213 is arranged adjacent to the first terminal 3 to ensure that the first terminal 3 can be bent and bend multiple times without affecting the normal transmission of the signal.

[0082] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The first terminal 3 includes a first conductive part 31, and the first terminal 3 is adapted to be connected to a first electronic component;

[0083] The first conductive part 31 is connected to the ground of the signal transmission harness, wherein when the first terminal 3 is connected to the first electronic component, the first conductive part 31 is connected to the ground of the first electronic component.

[0084] It is understandable that connecting the first conductive part 31 of the first terminal 3 to the ground of the first electronic component can increase the grounding area and reduce the grounding impedance of the signal transmission harness.

[0085] In some examples, the first conductive part 31 is, for example, a metal cover, which can also shield the signal at the first terminal 3.

[0086] In some examples, the first electronic component is, for example, the screen of a laptop computer. When the second signal transmission component 2 is connected to the screen, the first conductive part 31 is connected to the ground of the screen, which can effectively increase the grounding area and reduce the grounding impedance.

[0087] In some embodiments, see Figure 1 and Figure 2 The coaxial cable 11 includes an ultra-fine coaxial cable 111, the first end of which is connected to the second signal transmission component 2.

[0088] Understandably, by using the ultra-fine coaxial cable 111 to transmit signals, the signal transmission loss of the signal transmission harness is reduced, and the signal transmission performance of the signal transmission harness is improved.

[0089] It should be noted that the coaxial cable 11 can also be any other suitable wire harness that can improve signal transmission efficiency and reduce signal transmission loss.

[0090] In some examples, the diameter of the ultra-fine coaxial cable 111 is 0.41 mm ± 0.002 mm. It should be noted that this is only an example of the dimensions of the ultra-fine coaxial cable 111 and is not a specific limitation.

[0091] In some examples, the coaxial cable 11 also includes an outer insulating sheath 112, a shielding layer 113, an inner insulating layer 114, and a center conductor 115. The outer insulating sheath 112 is made of PFA plastic. The shielding layer 113 is made of 32 core tin-plated copper wires wound together and soldered to the exposed ground copper foil of the second signal transmission component 2. The inner insulating layer 114 is made of PFA plastic. The center conductor 115 includes 9 tin-plated copper strands and is soldered to the exposed signal line copper foil of the second signal transmission component 2.

[0092] See Figure 4 The signal transmission harness also includes insulating tape 4 and conductive tape 5. Insulating tape 4 is used to insulate the soldering parts of the coaxial cable 11 and the pads of the second signal transmission component 2. Conductive tape 5 covers the connection between the coaxial cable 11 and the second signal transmission component 2, shielding the exposed copper soldering parts of the coaxial cable 11 and the pads, and connecting the bottom GND exposed copper of the second signal transmission component 2. This expands the GND area that will later contact other grounded metals, which helps to increase the contact surface and reduce the grounding impedance of the entire component.

[0093] See Figure 4 The second signal transmission component 2 includes a grounding power circuit layer 22, upper and lower circuit isolation insulation layers 23 and an electrical signal transmission circuit layer 24 stacked in sequence. The electrical signal transmission circuit layer 24 is mainly composed of copper foil and surface insulating varnish; the upper and lower circuit isolation insulation layers 23 are mainly composed of polyester film coating; and the grounding power circuit layer 22 is mainly composed of copper foil and surface insulating varnish.

[0094] In some embodiments, see Figure 1 and Figure 2 The signal transmission harness also includes a second terminal 6, and the coaxial cable 11 is connected to the second terminal 6. The second terminal 6 is adapted to connect to a second electronic component.

[0095] It is understood that the second terminal 6 can be connected to the second electronic component to facilitate the connection between the coaxial cable 11 and the second electronic component.

[0096] In some embodiments, see Figure 1 and Figure 2The second terminal 6 includes a second conductive part 61, which is connected to the ground of the signal transmission harness. When the second terminal 6 is connected to the second electronic component, the second conductive part 61 is connected to the ground of the second electronic component.

[0097] It is understandable that connecting the second conductive part 61 of the second terminal 6 to the ground of the second electronic component can increase the grounding area and reduce the grounding impedance of the signal transmission harness.

[0098] In some examples, the second conductive part 61 is, for example, a metal cover, which can also shield the signal at the second terminal 6.

[0099] In some examples, the second electronic component is, for example, the motherboard of a laptop computer. When the coaxial cable 11 is connected to the motherboard, the second conductive part 61 is connected to the ground of the motherboard, which can effectively increase the grounding area and reduce the grounding impedance.

[0100] In some embodiments, see Figure 3 At least one of the coaxial cable 11 and the second signal transmission component 2 has a grounding portion 25.

[0101] Understandably, the grounding part 25 effectively increases the grounding area and reduces the grounding impedance, allowing interference from the signal transmission harness to be quickly discharged, effectively enhancing the anti-interference capability of the signal transmission harness and suppressing the signal radiation of the signal transmission harness.

[0102] In some embodiments, see Figure 3 The second signal transmission component 2 includes a body 26 and a connecting part 212. The connecting part 212 connects the body 26 and the coaxial line 11. The grounding part 25 is disposed adjacent to the connecting part 212.

[0103] It is understandable that the connecting part 212 is connected to the coaxial line 11, and the grounding part 25 is set at a position adjacent to the connecting part 212, so that the grounding part 25 can quickly discharge the impedance at the connection between the coaxial line 11 and the second signal transmission component 2, reduce the grounding impedance of the middle part of the signal transmission line harness, reduce the grounding impedance of the shielding layer of the coaxial line 11, enhance the shielding effect of the shielding layer, and enable interference to be discharged in a timely manner.

[0104] For example, "adjacent" can refer to a direct connection or a distance between them.

[0105] In some embodiments, the grounding portion 25 is provided on the side of the connecting portion 212 away from the body 26, or the grounding portion 25 is provided between the connecting portion 212 and the body 26.

[0106] It is understandable that the grounding part 25 can be connected to either side of the two sides of the part 212, which can effectively increase the grounding area and reduce the grounding impedance.

[0107] In some embodiments, see Figure 3 The second signal transmission component 2 has at least two spaced grounding portions 25.

[0108] Understandably, at least two grounding portions 25 can be used to increase the grounding area, thereby effectively reducing the grounding impedance of the signal transmission harness and ensuring that interference in the signal transmission harness can be quickly discharged.

[0109] At least two grounding parts 25 are spaced apart, so that the second signal transmission component 2 has multiple grounding points. The at least two grounding parts 25 can discharge interference from the signal transmission harness in sequence, effectively reducing the grounding impedance.

[0110] In some embodiments, see Figure 3 and Figure 5 At least two grounding portions 25 include a first grounding portion 251 and a second grounding portion 252. The first grounding portion 251 has a first impedance (ESR1+ESL1) with the end of the coaxial line 11 away from the second signal transmission component 2. The first grounding portion 251 and the second grounding portion 252 have a second impedance (ESR2+ESL2). The second grounding portion 252 and the end of the second signal transmission component 2 away from the coaxial line 11 have a third impedance (ESR3+ESL3).

[0111] It is understandable that there is impedance between any two of the ends of the coaxial line 11 away from the second signal transmission component 2, the first grounding part 251, the second grounding part 252, and the ends of the second signal transmission component 2 away from the coaxial line 11, so that the grounding part 25 can reduce the overall impedance to ground.

[0112] In some examples, the first impedance is equal to the second impedance, and the second impedance is equal to the third impedance. It can be understood that the impedance between the first grounding portion 251 and the end of the coaxial line 11 away from the second signal transmission component 2 is equal to the impedance between the first grounding portion 251 and the second grounding portion 252, and equal to the impedance between the second grounding portion 252 and the end of the second signal transmission component 2 away from the coaxial line 11. This divides the impedance of the signal transmission harness into three equal secondary impedances using the first grounding portion 251 and the second grounding portion 252, effectively reducing the grounding impedance of the shielding layer of the coaxial line 11, enhancing the shielding effect of the shielding layer, and improving the anti-interference capability and the ability to suppress signal radiation from the signal transmission harness.

[0113] In some embodiments, see Figure 2The signal transmission harness also includes a conversion connector 7, which is connected to the coaxial cable 11 or the second signal transmission component 2. The conversion connector 7 is adapted to be connected to a power conversion module to change the output voltage of the signal transmission harness.

[0114] Understandably, by reserving conversion connector 7 in the signal transmission harness, it is convenient to connect the power conversion module to the signal transmission harness, so that the power conversion module can change the output voltage of the signal transmission harness, making the signal transmission harness suitable for different electronic devices and improving the compatibility of the signal transmission harness.

[0115] For example, when a signal transmission harness is used in a laptop computer, the signal transmission harness equipped with the conversion connector 7 can be compatible with harness screens from different brands, eliminating the need to manufacture multiple harnesses during the production process.

[0116] In some embodiments, see Figure 2 , Figure 6 and Figure 7 The conversion connector 7 includes a frame 71, a first signal spring 72 and a second signal spring 73. One end of the first signal spring 72 and one end of the second signal spring 73 are both connected to the frame 71. The other end of the first signal spring 72 and the other end of the second signal spring 73 can be switched between an abutting state and a separated state so that the power conversion module can be inserted between the other end of the first signal spring 72 and the other end of the second signal spring 73.

[0117] Understandably, when no power conversion module is inserted into the conversion connector 7, the other ends of the first signal spring 72 and the second signal spring 73 are in contact. When it is necessary to change the output voltage of the signal transmission harness, the power conversion module is inserted between the other ends of the first signal spring 72 and the second signal spring 73, so that the first signal spring 72 and the second signal spring 73 are spaced apart. The other end of the first signal spring 72 is connected to the power conversion module, and the other end of the second signal spring 73 is connected to the power conversion module. At this time, the signal will be transmitted from the first signal spring 72 to the power conversion module, and then to the second signal spring 73, so that the power conversion module can adjust the output voltage of the signal transmission harness.

[0118] In some embodiments, see Figure 2 , Figure 6 and Figure 7 The frame 71 has a snap-fit ​​portion 74, which is adapted to snap-fit ​​with the power conversion module. It can be understood that by using the snap-fit ​​portion 74 to snap-fit ​​with the power conversion module, the power conversion module can be stably inserted into the conversion connector 7.

[0119] According to a second aspect of this application, this application provides an electronic device including the signal transmission harness described above.

[0120] It is understandable that by using the coaxial cable 11 to transmit signals, the signal transmission loss of the signal transmission harness is reduced, thereby improving the signal transmission performance of the signal transmission harness. Simultaneously, signal transmission is achieved by using the second signal transmission component 2 in conjunction with the coaxial cable 11, and at least a portion of the second signal transmission component 2 is configured as a flexible structure. This flexible structure possesses bending resistance, improving the bending performance of the signal transmission harness. In other words, this application improves the signal transmission performance and bending performance of the signal transmission harness by utilizing the coaxial cable 11 and at least a portion of the second signal transmission component 2, which has a flexible structure, thereby enhancing the operational stability of the electronic device.

[0121] In some embodiments, the electronic device includes a body and a display screen, the display screen being rotatable relative to the body, wherein a coaxial cable 11 is disposed within the body and connected to the mainboard of the body, and a second signal transmission component 2 is connected to the coaxial cable 11 and the display screen.

[0122] It is understandable that the coaxial cable 11 is placed inside the main body to connect with the motherboard. The coaxial cable 11 has the characteristics of stable signal transmission and low loss, which can adapt to the strong interference environment inside the main body. It can reduce the loss of signal transmission from the motherboard to the display screen, thereby avoiding screen flickering or display abnormalities caused by high signal transmission loss.

[0123] At least part of the second signal transmission component 2 is a flexible structure, which improves the bending performance of the second signal transmission component 2. During the opening and closing of the display screen and after multiple opening and closing, the second signal transmission component 2 will not break and can still play a stable signal transmission function, so that the display screen can display normally.

[0124] In some embodiments, a flexible structure for the signal transmission harness is provided at the connection between the display screen and the main body.

[0125] It is understandable that the display screen will rotate relative to the main body, meaning that the connection between the display screen and the main body is a place where bending is likely to occur. Therefore, the flexible structure of the signal transmission harness is set at the connection between the display screen and the main body. The flexible structure has excellent bending performance and is less affected by bending, so that the second signal transmission component 2 will not break and can transmit signals stably.

[0126] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
