[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] According to the first aspect of the present application, refer to Figures 1 to 7 The present application provides a signal transmission harness, including a first signal transmission component 1 and a second signal transmission component 2, wherein the first signal transmission component 1 includes a coaxial line 11, the second signal transmission component 2 is connected to the coaxial line 11, and at least a portion of the second signal transmission component 2 is a flexible structure.

[0054] It can be understood that by using the coaxial line 11 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. At the same time, the second signal transmission component 2 and the coaxial line 11 are used in conjunction to transmit signals, and at least part of the second signal transmission component 2 is set as a flexible structure. The flexible structure has the characteristic of being resistant to bending, which improves the bending performance of the signal transmission harness. In other words, the present application improves the signal transmission performance of the signal transmission harness by using the coaxial line 11 and the second signal transmission component 2, at least part of which is a flexible structure, to form a signal transmission harness, while also improving the bending performance of the signal transmission harness.

[0055] In some examples, the signal transmission harness can be applied to a laptop computer, where the coaxial line 11 connects the motherboard of the laptop computer and the second signal transmission component 2, the second signal transmission component 2 is connected to the screen of the laptop computer, and the flexible structure is set in a position that is often bent.

[0056] Since the motherboard of the laptop is a strong interference source, the coaxial line 11 is arranged on the motherboard. By utilizing the stable signal transmission and low loss characteristics of the coaxial line 11, screen flickering or display abnormality caused by large signal transmission loss can be avoided.

[0057] The flexible structure can still transmit signals normally when it is bent and after being bent multiple times, so that the laptop will not have problems such as signal transmission harness breakage or signal transmission abnormality after being opened and closed multiple times.

[0058] It should be noted that a laptop computer is used as an example here, and the signal transmission harness of the present application is not limited to be used only 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 part 21 is a flexible structure.

[0061] It can be understood that the second signal transmission component 2 and the coaxial line 11 are used in cooperation to perform signal transmission, and at least part of the signal transmission part 21 is set as a flexible structure. The signal transmission part 21 of the flexible structure has the characteristic of being resistant to bending, thereby improving the bending performance of the signal transmission harness.

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

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

[0064] It can be understood that the first flexible portion 211 has excellent bending performance, and the first flexible portion 211 is used as at least a part of the second signal transmission component 2 to improve the bending performance of the second signal transmission component 2.

[0065] The connection between the coaxial line 11 and the second signal transmission component 2 is prone to bending. The first flexible portion 211 is arranged at the connection between the second signal transmission component 2 and the coaxial line 11, so as to improve the bending reliability between the coaxial line 11 and the second signal transmission component 2 and improve the connection stability between the coaxial line 11 and the second signal transmission component 2.

[0066] In some examples, the first flexible portion 211 is disposed at the connection between the second signal transmission component 2 and the coaxial line 11, which means that the connection between the second signal transmission component 2 and the coaxial line 11 is adjacent to the first flexible portion 211. The first flexible portion 211 is disposed at the connection between the second signal transmission component 2 and the coaxial line 11, which means that the connection between the second signal transmission component 2 and the coaxial line 11 is adjacent to the first flexible portion 211 but separated by a certain distance.

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

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

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

[0070] It can be understood that the first flexible portion 211 is directly connected to the connecting portion 212 , which can improve the bending performance at the connecting portion 212 .

[0071] Specifically, the first flexible portion 211 and the connecting portion 212 are spaced apart from each other.

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

[0073] That is to say, the first flexible portion 211 may be directly connected to the connecting portion 212 or may be spaced apart from the connecting portion 212 , which may be determined specifically 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 parts 21 include a second flexible part 213 , and the first flexible part 211 and the second flexible part 213 are arranged at intervals.

[0075] It can be understood that both the first flexible portion 211 and the second flexible portion 213 have excellent bending properties, thereby improving the bending properties of the second signal transmission component 2 .

[0076] The first flexible portion 211 and the second flexible portion 213 are arranged at intervals, thereby improving the bending performance of different positions of the second signal transmission component 2, so that the signal transmission harness can be applied to situations requiring multiple bending positions.

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

[0078] It can be understood that the first wiring terminal 3 can be used to connect to the electronic device to facilitate the connection between the second signal transmission component 2 and the electronic device.

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

[0080] It can be understood that arranging the second flexible portion 213 adjacent to the first wiring terminal 3 can improve the bending performance at the first wiring terminal 3 .

[0081] It is understandable that when the first terminal 3 is connected to an electronic device, the first terminal 3 is prone to bending, and the second flexible portion 213 is arranged adjacent to the first terminal 3 to ensure that the first terminal 3 can be bent and bent 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 portion 31, and the first terminal 3 is suitable for connecting to a first electronic component;

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

[0084] It can be understood that the first conductive portion 31 of the first terminal 3 is connected to the ground of the first electronic component, which can increase the grounding area and reduce the grounding impedance of the signal transmission harness.

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

[0086] In some examples, the first electronic component is, for example, a screen of a laptop computer. When the second signal transmission component 2 is connected to the screen, the first conductive portion 31 is electrically 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 line 11 includes an extremely fine coaxial line 111 , and a first end of the extremely fine coaxial line 111 is connected to the second signal transmission component 2 .

[0088] It can be understood that by using the ultra-fine coaxial line 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 line 11 may 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-thin coaxial line 111 is 0.41 mm±0.002 mm. It should be noted that the size of the ultra-thin coaxial line 111 is merely exemplified and is not specifically limited.

[0091] In some examples, the coaxial line 11 also includes a coaxial line outer insulation layer sheath 112, a coaxial line shielding layer 113, a coaxial line inner insulation layer 114, and a coaxial line center conductor 115. The material of the coaxial line outer insulation layer sheath 112 is PFA plastic, the coaxial line shielding layer 113 is wound with 32 core tinned copper wires and welded together with the exposed grounding copper skin of the second signal transmission component 2; the material of the coaxial line inner insulation layer 114 is PFA plastic, and the coaxial line center conductor 115 includes 9 tinned copper strands and is welded together with the exposed signal line copper skin of the second signal transmission component 2.

[0092] See also Figure 4 The signal transmission harness also includes an insulating tape 4 and a conductive tape 5. The insulating tape 4 is used to insulate the welding part of the coaxial line 11 and the pad of the second signal transmission component 2. The conductive tape 5 covers the connection between the coaxial line 11 and the second signal transmission component 2, and is used to shield the copper-exposed welding part and pad of the coaxial line 11, and connect the bottom GND exposed copper of the second signal transmission component 2, expanding the GND area that contacts with other grounded metals in the later stage, which is beneficial to increase the contact surface and reduce the ground impedance of the entire component.

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

[0094] In some embodiments, see Figure 1 and Figure 2 The signal transmission harness further includes a second terminal 6, the coaxial line 11 is connected to the second terminal 6, and the second terminal 6 is suitable for connecting to a second electronic component.

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

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

[0097] It can be understood that the second conductive portion 61 of the second terminal 6 is connected to the ground of the second electronic component, which can increase the grounding area and reduce the grounding impedance of the signal transmission harness.

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

[0099] In some examples, the second electronic component is, for example, a motherboard of a laptop computer. When the coaxial line 11 is connected to the motherboard, the second conductive portion 61 is electrically 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 line 11 and the second signal transmission component 2 is formed with a grounding portion 25 .

[0101] It can be understood that the grounding portion 25 effectively increases the grounding area and reduces the grounding impedance, so that the interference of the signal transmission harness can be quickly discharged, effectively enhancing the anti-interference ability of the signal transmission harness and the ability to suppress the signal of the signal transmission harness from radiating outward.

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

[0103] It can be understood that the connecting part 212 is connected to the coaxial line 11, and the grounding part 25 is arranged 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, thereby reducing the grounding impedance of the middle part of the signal transmission harness, reducing the grounding impedance of the shielding layer of the coaxial line 11, and enhancing the shielding effect of the shielding layer, so that interference can be discharged in time.

[0104] Illustratively, adjacent may mean directly connected or spaced a certain distance apart.

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

[0106] It can be understood that the grounding portion 25 can be connected to either side of the connecting portion 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 is formed with at least two grounding portions 25 disposed at intervals.

[0108] It can be understood that 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 the interference of the signal transmission harness can be quickly discharged.

[0109] At least two grounding portions 25 are arranged at intervals, so that the second signal transmission component 2 forms a plurality of grounding points. At least two grounding portions 25 can discharge the interference of the signal transmission harness in turn, effectively reducing the grounding impedance.

[0110] In some embodiments, see Figure 3 and Figure 5 At least two grounding parts 25 include a first grounding part 251 and a second grounding part 252. A first impedance (ESR1+ESL1) is provided between the first grounding part 251 and an end of the coaxial line 11 away from the second signal transmission component 2. A second impedance (ESR2+ESL2) is provided between the first grounding part 251 and the second grounding part 252. A third impedance (ESR3+ESL3) is provided between the second grounding part 252 and an end of the second signal transmission component 2 away from the coaxial line 11.

[0111] It can be understood that there is impedance between any two of the end of the coaxial line 11 away from the second signal transmission component 2, the first grounding portion 251, the second grounding portion 252, and the end of the second signal transmission component 2 away from the coaxial line 11, so that the grounding portion 25 can play a role in reducing the overall impedance to the 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 is understandable 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. The impedance of the signal transmission harness is divided into three equal secondary impedances by using the first grounding portion 251 and the second grounding portion 252, which can effectively reduce the grounding impedance of the shielding layer of the coaxial line 11, enhance the shielding effect of the shielding layer, and enhance the anti-interference ability of the signal transmission harness and the ability to suppress the signal radiation of 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 line 11 or the second signal transmission component 2. The conversion connector 7 is suitable for connecting to the power conversion module to change the output voltage of the signal transmission harness.

[0114] It can be understood that by reserving a conversion connector 7 in the signal transmission harness, the connection between the power conversion module and the signal transmission harness is facilitated, so that the power conversion module can change the output voltage of the signal transmission harness, so that the signal transmission harness can be suitable for different electronic devices, thereby improving the compatibility of the signal transmission harness.

[0115] Exemplarily, when the signal transmission harness is applied to a notebook computer, the signal transmission harness provided with the conversion connector 7 can be compatible with harness screens of different brands, and there is no need to produce 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 a contact state and a separation 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] It can be understood that when no power conversion module is inserted into the conversion connector 7, the other end of the first signal spring 72 and the other end of the second signal spring 73 are in contact. When the output voltage of the signal transmission harness needs to be changed, the power conversion module is inserted between the other end of the first signal spring 72 and the other end of the second signal spring 73, so that the first signal spring 72 and the second signal spring 73 are arranged at intervals, 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 transmitted 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 is formed with a clamping portion 74, which is suitable for clamping with the power conversion module. It can be understood that the clamping portion 74 is clamped with the power conversion module so that the power conversion module can be stably inserted into the conversion connector 7.

[0119] According to a second aspect of the present application, the present application provides an electronic device, comprising the above-mentioned signal transmission harness.

[0120] It can be understood that by using the coaxial line 11 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. At the same time, the second signal transmission component 2 and the coaxial line 11 are used to cooperate for signal transmission, and at least part of the second signal transmission component 2 is set as a flexible structure. The flexible structure has the characteristic of being resistant to bending, which improves the bending performance of the signal transmission harness. In other words, the present application improves the signal transmission performance of the signal transmission harness by using the coaxial line 11 and the second signal transmission component 2 of which at least part of the structure is a flexible structure to form a signal transmission harness, while also improving the bending performance of the signal transmission harness, thereby improving the working stability of the electronic device.

[0121] In some embodiments, the electronic device includes a main body and a display screen, and the display screen can rotate relative to the main body, wherein the coaxial line 11 is arranged in the main body and connected to the main board of the main body, and the second signal transmission component 2 connects the coaxial line 11 and the display screen.

[0122] It is understandable that the coaxial line 11 is arranged in the main body so as to connect the main board with the coaxial line 11. The coaxial line 11 has the characteristics of stable signal transmission and low loss, can adapt to the environment with strong interference in the main body, can reduce the loss of signal transmission from the main board to the display screen, and thus avoid the display screen flickering problem or display abnormality caused by large 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 process of the display screen and after opening and closing multiple times, the second signal transmission component 2 will not break and can still perform a stable signal transmission function, so that the display screen can display normally.

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

[0125] It can be understood that the display screen will rotate relative to the main body, that is, the connection between the display screen and the main body is a place where bending is prone to occur, so 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.
