Description

Technical Field

[0001] This disclosure relates to the field of data cable technology, and in particular to an anti-interference data transmission harness and an automotive central control connection cable. Background Technology

[0002] As a crucial bridge connecting the vehicle's infotainment system with external devices (such as mobile phones and USB flash drives), the in-vehicle data cable plays a key role in modern automobiles. With the diversification of automotive infotainment functions, the application of the data cable has expanded beyond basic charging to include data transmission, intelligent connectivity, multimedia entertainment, and many other areas.

[0003] As the automotive industry becomes increasingly intelligent, in-vehicle central control modules will further develop towards higher speeds, wireless connectivity, and integration. For example, in the future, advanced functions such as 8K video output and 5G network sharing may be achieved through a single data cable. However, currently, different types of central control connection cables, such as the integrated vehicle charger disclosed in patent publication number CN210490521U, when applied to automotive intelligent central control modules, can cause interference to the signals transmitted by the central control connection cables due to the presence of various electronic devices and circuits inside the vehicle, such as engine control systems, audio systems, and wireless communication modules. These devices generate electromagnetic radiation during operation, which may lead to data transmission errors or interruptions. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an anti-interference data transmission harness and automotive central control connection cable that can suppress electromagnetic interference and ensure normal communication and transmission between external devices and the vehicle central control module.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] An anti-interference data transmission harness includes a connection terminal, a data transmission line, a stereo connector, and a magnetic ring assembly. The data transmission line and the stereo connector are both electrically connected to the connection terminal. The connection terminal is used to connect to a car's central control unit. The magnetic ring assembly includes a mounting housing, a first magnetic block, and a second magnetic block. The mounting housing includes an upper housing, a lower housing, and a rotating shaft. The upper housing is rotatably connected to the lower housing via the rotating shaft. The upper housing has a first receiving groove, and the lower housing has a second receiving groove. The first magnetic block is located in the first receiving groove, and the second magnetic block is located in the second receiving groove. The upper housing is used to engage with the lower housing so that the inner sides of the first and second magnetic blocks together form a mounting hole. The data transmission line passes through the mounting hole.

[0007] In one embodiment, the outer wall of the upper half of the outer shell has a buckle opening, and the outer wall of the lower half of the outer shell has a buckle protrusion. The buckle protrusion passes through the buckle opening so that the upper half of the outer shell and the lower half of the outer shell can be fastened together.

[0008] In one embodiment, the data transmission line includes a data cable socket, a middle conductor, and a branch line group connected in sequence. The branch line group is connected to the connection terminal. The data cable socket is used for electrical connection to an external device. The middle conductor passes through the mounting hole.

[0009] In one embodiment, the first magnetic block has a first abutting surface, the upper half of the outer shell has a first mounting surface, the first mounting surface is located on the bottom surface of the first receiving groove, and the first abutting surface abuts against the first mounting surface.

[0010] In one embodiment, the first magnetic block has a first snap-fit ​​groove, and the upper half of the outer shell has a first snap-fit ​​protrusion. The first snap-fit ​​protrusion is located on the inner wall of the first receiving groove and is disposed in the first snap-fit ​​groove.

[0011] In one embodiment, the second magnetic block has a second abutting surface, the lower half of the outer shell has a second mounting surface, the second mounting surface is located in the second receiving groove, and the second abutting surface abuts against the second mounting surface.

[0012] In one embodiment, the second magnetic block has a second snap-fit ​​groove, and the lower half of the outer shell has a second snap-fit ​​protrusion. The second snap-fit ​​protrusion is located on the inner wall of the second receiving groove and is disposed in the second snap-fit ​​groove.

[0013] In one embodiment, the anti-interference data transmission harness further includes an insulated block, the insulated block having a first through hole and a second through hole, the data transmission line passing through the first through hole, and the stereo wiring passing through the second through hole.

[0014] In one embodiment, the anti-interference data transmission harness further includes a radio frequency (RF) connector, and the insulated block is provided with a third via hole through which the RF connector passes.

[0015] A car central control connection cable includes an anti-interference data transmission harness as described in any of the above embodiments.

[0016] Compared with the prior art, this disclosure has at least the following advantages:

[0017] 1. The aforementioned anti-interference data transmission harness uses a magnetic ring assembly, wherein the inner sides of the first magnetic block and the second magnetic block together form a mounting hole for the data transmission line to pass through, so that the assembly is installed on the outer periphery of the data transmission line. Due to the use of the first magnetic block and the second magnetic block, when the magnetic block is applied to the automotive intelligent central control module, it can absorb or reflect common-mode noise in the harness according to its own high-frequency impedance characteristics, thereby suppressing high-frequency electromagnetic interference. It can also retain low-frequency effective signals to ensure the stability of data transmission and communication between external devices and the vehicle central control module.

[0018] 2. Since the housing consists of an upper half, a lower half, and a pivot, after inserting the first and second magnetic blocks, one of the two magnetic blocks should be positioned against the data transmission line. Then, the upper or lower half of the housing can be moved to engage with it, thus completing the installation of the magnetic ring assembly. When the assembly needs to be removed, the upper or lower half of the housing can be pried open by hand to remove the assembly. Therefore, the magnetic ring assembly is easy to install and remove, and the installation and removal difficulty is low. Attached Figure Description

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0035] Please see Figure 1 This is an embodiment of the anti-interference data transmission harness 10 of the present invention, including a connection terminal 100, a data transmission line 200, a stereo connector 300, and a magnetic ring assembly 400. The power terminals of the data transmission line 200 and the stereo connector 300 are both electrically connected to the connection terminal 100. The connection terminal 100 is used to connect to the car's central control unit, such as... Figure 2 As shown, the magnetic ring assembly 400 includes a mounting housing 410, a first magnetic block 420, and a second magnetic block 430. The mounting housing 410 includes an upper housing 411, a lower housing 412, and a rotating shaft 413. The upper housing 411 is rotatably connected to the lower housing 412 via the rotating shaft 413. For example, both the upper housing 411 and the lower housing 412 are rotatably mounted on the rotating shaft 413, forming a hinge structure. Figures 4 to 6 As shown, the upper half of the outer shell 411 has a first receiving groove 411a, and the lower half of the outer shell 412 has a second receiving groove 412a. The first magnetic block 420 is located in the first receiving groove 411a, and the second magnetic block 430 is located in the second receiving groove 412a. The upper half of the outer shell 411 is used to fasten and connect with the lower half of the outer shell 412 so that the inner sides of the first magnetic block 420 and the second magnetic block 430 together form a mounting hole 400a. The data transmission line 200 passes through the mounting hole 400a.

[0036] It is understood that the anti-interference data transmission harness 10 uses a magnetic ring assembly 400, wherein the inner sides of the first magnetic block 420 and the second magnetic block 430 together form a mounting hole 400a for the data transmission line 200 to pass through, so that the assembly is mounted on the outer periphery of the data transmission line 200. Due to the use of the first magnetic block 420 and the second magnetic block 430, when applied to an automotive intelligent central control module, these magnetic blocks can absorb or reflect common-mode noise in the harness based on their own high-frequency impedance characteristics, thereby suppressing high-frequency electromagnetic interference. They can also retain low-frequency effective signals to ensure data transmission and communication between external devices and the vehicle central control module. Stability; In addition, since the mounting housing 410 adopts an upper half housing 411, a lower half housing 412 and a rotating shaft 413, after the first magnetic block 420 and the second magnetic block 430 are inserted, one of the two magnetic blocks is made to abut against the data transmission line 200. Then, the upper half housing 411 or the lower half housing 412 is moved to make the upper half housing 411 and the lower half housing 412 snap together, thereby completing the installation of the magnetic ring assembly 400. When it is necessary to remove the assembly, it is only necessary to manually pry open the upper half housing 411 or the lower half housing 412 to remove the assembly. No auxiliary tools are needed during the installation and removal process. Therefore, the magnetic ring assembly 400 is easy to install and remove and has a low installation and removal difficulty.

[0037] In another embodiment, the polarities of the first magnetic block 420 and the second magnetic block 430 can be the same or opposite. When the polarities are opposite, it can help to fasten the upper half shell 411 and the lower half shell 412. When the polarities are the same, since the first magnetic block 420 and the second magnetic block 430 are small in size and far apart, and a data transmission line is also inserted in the middle, the magnetic force that repels each other is small and does not affect the fastening of the upper half shell 411 and the lower half shell 412.

[0038] like Figure 9 and Figure 10 This is a physical diagram of the anti-interference data transmission harness 10, so that those skilled in the art can understand the structural principle of the solution and prove that the solution exists and can be implemented.

[0039] like Figures 3 to 5As shown, in one embodiment, the outer wall of the upper half-shell 411 has a protruding snap-fit ​​opening 411b, and the outer wall of the lower half-shell 412 has a snap-fit ​​protrusion 4121. The snap-fit ​​protrusion 4121 passes through the snap-fit ​​opening 411b, so that the upper half-shell 411 and the lower half-shell 412 are engaged. It can be understood that when installing the magnetic ring assembly 400, by moving the upper half-shell 411 or the lower half-shell 412, the snap-fit ​​protrusion 4121 is engaged with the snap-fit ​​opening 411b, thereby achieving the effect of installing the magnetic ring assembly 400 on the outer periphery of the data transmission line 200; when it is necessary to remove the magnetic ring assembly 400, the lower half-shell 412 is pried open by hand to move the snap-fit ​​opening 411b away from the snap-fit ​​protrusion 4121, and finally the magnetic ring assembly 400 is removed, thereby achieving the effect of removing the magnetic ring assembly 400 from the outer periphery of the data transmission line 200. Thus, by having the snap-fit ​​protrusion 4121 engage with the snap-fit ​​opening 411b, the magnetic ring assembly 400 is easy to assemble and disassemble with low difficulty.

[0040] like Figure 1 As shown, in one embodiment, the data transmission line 200 includes a data cable socket 210, an intermediate conductor 220, and a branch line group 230 connected in sequence. The branch line group 230 is connected to the connection terminal 100. The data cable socket 210 is used for electrical connection to external devices, and the intermediate conductor 220 passes through the mounting hole 400a. It can be understood that when the connection terminal 100 is connected to the port of the vehicle's central control unit, and the data cable socket 210 is connected to an external device, the transmission signal between the vehicle's main control unit and the external device must pass through the intermediate conductor 220. This location is susceptible to external signal interference, affecting communication stability. Therefore, the magnetic ring assembly 400 is installed on the outer periphery of the intermediate conductor 220 to suppress external high-frequency magnetic field interference and ensure communication stability between the vehicle and the central control unit.

[0041] like Figure 4 , Figure 6 and Figure 7As shown, in one embodiment, the first magnetic block 420 has a first abutting surface 421, and the upper half of the outer shell 411 is provided with a first mounting surface 4111. The first mounting surface 4111 is located on the bottom surface of the first receiving groove 411a. The first abutting surface 421 abuts against the first mounting surface 4111, so that after the first magnetic block 420 is installed in the first receiving groove 411a, the first abutting surface 421 cooperates with the first mounting surface 4111 to suppress the first magnetic block 420 from rotating under external force. Furthermore, the first magnetic block 420 has a first snap-fit ​​groove 422, and the upper half of the outer shell 411 has a first snap-fit ​​protrusion 4112. The first snap-fit ​​protrusion 4112 is located on the inner wall of the first receiving groove 411a and is disposed in the first snap-fit ​​groove 422. In this way, the first magnetic block 420 can be fixed by the cooperation between the first snap-fit ​​protrusion 4112 and the first snap-fit ​​groove 422, so that the first magnetic block 420 is not easy to detach from the first receiving groove 411a.

[0042] like Figures 5 to 7 As shown, in one embodiment, the second magnetic block 430 has a second abutting surface 431, and the lower half of the outer shell 412 is provided with a second mounting surface 4122. The second mounting surface 4122 is located in the second receiving groove 412a, and the second abutting surface 431 abuts against the second mounting surface 4122, so that after the second magnetic block 430 is installed in the second receiving groove 412a, the second abutting surface 431 cooperates with the second mounting surface 4122 to suppress the second magnetic block 430 from rotating under external force. Furthermore, the second magnetic block 430 has a second snap-fit ​​groove 432, and the lower half of the outer shell 412 has a second snap-fit ​​protrusion 4123. The second snap-fit ​​protrusion 4123 is located on the inner wall of the second receiving groove 412a and is disposed in the second snap-fit ​​groove 432. In this way, the second magnetic block 430 can be fixed by the cooperation between the second snap-fit ​​protrusion 4123 and the second snap-fit ​​groove 432, so that the second magnetic block 430 is not easy to detach from the second receiving groove 412a.

[0043] like Figure 1 and Figure 8 As shown, in one embodiment, the anti-interference data transmission harness 10 further includes an insulated block 500. The insulated block 500 has a first through hole 501 and a second through hole 502. The data transmission line 200 passes through the first through hole 501, and the stereo wiring 300 passes through the second through hole 502, so that the data transmission line 200 and the stereo wiring 300 are not easily separated by the insulated block 500, and at the same time, it prevents any two components of the data transmission line 200, the stereo wiring 300 and the connecting terminal 100 from being broken.

[0044] like Figure 1 and Figure 8As shown, in one embodiment, the anti-interference data transmission harness 10 further includes a radio frequency (RF) connector 600. The insulated block 500 also has a third via 503 through which the RF connector 600 passes, preventing it from detaching from the insulated block 500. It can be understood that when the RF connector 600 is applied to an in-vehicle central control module, it has good shielding performance, effectively blocking external interference signals, providing a stable RF signal transmission environment, and ensuring the normal operation of the vehicle's central control module.

[0045] This disclosure also provides a car central control connection cable, including the anti-interference data transmission harness 10 of any of the above embodiments.

[0046] Compared with the prior art, this disclosure has at least the following advantages:

[0047] 1. The aforementioned anti-interference data transmission harness 10 uses a magnetic ring assembly 400, wherein the inner sides of the first magnetic block 420 and the second magnetic block 430 together form a mounting hole 400a for the data transmission line 200 to pass through, so that the assembly is installed on the outer periphery of the data transmission line 200. Due to the use of the first magnetic block 420 and the second magnetic block 430, when the magnetic blocks are applied to the automotive intelligent central control module, they can absorb or reflect common-mode noise in the harness according to their own high-frequency impedance characteristics, thereby suppressing high-frequency electromagnetic interference. They can also retain low-frequency effective signals to ensure the stability of data transmission and communication between external devices and the vehicle central control module.

[0048] 2. Since the housing 410 is composed of an upper housing 411, a lower housing 412, and a rotating shaft 413, after the first magnetic block 420 and the second magnetic block 430 are inserted, one of the two magnetic blocks is made to abut against the data transmission line 200. Then, the upper housing 411 or the lower housing 412 is moved to make the upper housing 411 and the lower housing 412 snap together, thereby completing the installation of the magnetic ring assembly 400. When it is necessary to remove the assembly, it is only necessary to manually pry open the upper housing 411 or the lower housing 412 to remove the assembly. Therefore, the magnetic ring assembly 400 is easy to install and remove and has low installation and removal difficulty.

[0049] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
