Description

Technical Field

[0001] This utility model relates to the field of HDMI technology, and in particular to an HDMI cable and instrument. Background Technology

[0002] Currently, many products on the market (such as aerial drones, optoelectronic pods, medical equipment, and testing equipment) require the use of HDMI cables to transmit high-definition video signals. In some of these products, especially those internal to the device, the HDMI cables are routed using through-holes. Since HDMI cables have HDMI connectors at both ends, and these connectors are much larger than the cable's outer diameter, the product needs to have large through-holes to allow the HDMI connectors to pass through. These through-holes take up too much space in the product. Utility Model Content

[0003] The main purpose of this utility model is to provide an HDMI cable that allows the HDMI cable to pass through holes with smaller diameters, thereby reducing the requirements for the diameter of the through holes on the product and reducing the space occupied by the through holes on the product.

[0004] To achieve the above objectives, the present invention proposes an HDMI cable, comprising a cable body and two HDMI connectors respectively connected to both ends of the cable body. At least one end of the cable body is electrically connected to the corresponding HDMI connector via a connector. The connector comprises a first part and a second part. The first part is connected to the end of the cable body, and the second part is connected to the PCB board of the HDMI connector. The first part and the second part are detachably connected. The width of the first part is greater than or equal to the outer diameter of the cable body and less than the maximum width of the HDMI connector.

[0005] In some embodiments, both HDMI connectors are electrically connected to the corresponding ends of the cable via a connector.

[0006] In some embodiments, the first part is a male seat and the second part is a female seat; or, the first part is a female seat and the second part is a male seat.

[0007] And / or, the connector is a connector with a locking mechanism; or, the HDMI connector is provided with an anti-detachment structure, which acts on the first part to prevent the first part from detaching from the second part on its own.

[0008] In some embodiments, the signal lines in the line body are all coaxial lines, and the connector is a coaxial connector.

[0009] In some embodiments, the cable body does not have a reserved wire corresponding to the reserved pin of the HDMI connector.

[0010] In some embodiments, the shielding layers of the coaxial cable are all electrically connected to the outer shell of the first part, and the outer shell of the first part is electrically connected to the grounding pin of the PCB board; the cable body does not have at least one of the following: data 0 shielding line, data 1 shielding line, data 2 shielding line, clock shielding line, and DDC / CEC ground line.

[0011] In some embodiments, the line body does not include a data 0 shield line, a data 1 shield line, a data 2 shield line, a clock shield line, and a DDC / CEC ground line, and the connector is a 14-pin coaxial connector;

[0012] The total number of signal lines in the line body is 13. The 13 signal lines in the line body are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line, SCL line, SDA line, power line, and hot-swap monitoring line.

[0013] Alternatively, the total number of signal lines in the line body is 14, and the 14 signal lines in the line body are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line, reserved line, SCL line, SDA line, power line and hot-swap monitoring line.

[0014] In some embodiments, the total number of signal lines in the line body is 14. The 14 signal lines in the line body are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line, SCL line, SDA line, power line, hot-plug monitoring line, and the data 0 shield line, the data 1 shield line, the data 2 shield line, the clock shield line, or the DDC / CEC ground line.

[0015] This utility model also proposes an instrument or device, including at least one of the above-mentioned HDMI cables.

[0016] In some embodiments, the instrument is provided with a cable pass-through hole, through which the HDMI cable passes. The diameter of the cable pass-through hole is greater than the width of the first portion and less than the maximum width of the HDMI connector.

[0017] The technical solution of this utility model for an HDMI cable involves a detachable connection between at least one end of the cable and an HDMI connector via a connector. The first part of the connector is connected to the end of the cable, and the second part of the connector is connected to the PCB of the HDMI connector. Thus, when the HDMI cable needs to be routed through a hole, the first part of the connector can be detached from the second part, separating the HDMI connector from the cable. The first part, with one end of the cable passing through it, is then passed through a through hole, and finally reconnected to the second part of the HDMI connector to complete the HDMI cable routing. Furthermore, since the smallest hole through which the first part can pass is smaller than the smallest hole through which the HDMI connector can pass, products using this utility model's HDMI cable only need to have through holes large enough to allow the first part to pass through during routing, reducing the requirements for the hole diameter and thus minimizing the space occupied by the through holes.

[0028] This utility model proposes an HDMI cable.

[0029] Reference Figures 1 to 3 In this embodiment, the HDMI cable includes a cable body 10 and two HDMI connectors 20 connected to both ends of the cable body 10. At least one end of the cable body 10 is electrically connected to the corresponding HDMI connector 20 through a connector 30. The connector 30 includes a first part 31 and a second part 32. The first part 31 is connected to the end of the cable body 10, and the second part 32 is connected to the PCB board 21 of the HDMI connector 20. The first part 31 and the second part 32 are detachably connected (e.g., plugged in, snapped in, etc.), that is, at least one end of the cable body 10 is detachably connected to the HDMI connector 20. The diameter of the smallest hole that the first part 31 can pass through is smaller than the diameter of the smallest hole that the HDMI connector 20 can pass through, that is, the size of the first part 31 is smaller than the size of the HDMI connector 20 (e.g., the width of the first part 31 is smaller than the width of the HDMI connector 20).

[0030] In this embodiment of the HDMI cable design, at least one end of the cable body 10 is detachably connected to the HDMI connector 20 via a connector 30. The first part 31 of the connector 30 is connected to the end of the cable body 10, and the second part 32 of the connector 30 is connected to the PCB of the HDMI connector 20. Thus, when the HDMI cable needs to be routed through a hole, the first part 31 of the connector 30 can be detached from the second part 32, separating the HDMI connector 20 from the cable body 10, allowing the first part 31 to carry one end of the cable body 10. After passing through the cable through the hole, the first part 31 that has passed through the cable through the hole is reconnected to the second part 32 of the HDMI connector 20 to complete the HDMI cable through-hole routing. Since the smallest hole through which the first part 31 can pass is smaller than the smallest hole through which the HDMI connector 20 can pass, when routing the HDMI cable using this embodiment, only a cable through hole of a size that allows the first part 31 to pass through needs to be made, which reduces the requirement for the diameter of the cable through hole and makes the cable through hole occupy less space in the product.

[0031] In some embodiments, both HDMI connectors 20 are electrically connected to the corresponding ends of the cable body 10 via a connector 30. This allows the cable body 10 and the HDMI connectors 20 at both ends to be detached. When either the cable body 10 or the HDMI connector 20 fails, only the damaged portion of the HDMI cable needs to be replaced, while the undamaged portion can be retained, eliminating the need to replace the entire HDMI cable and reducing maintenance costs for devices using the HDMI cable of this embodiment. For example, if one end of the HDMI cable's HDMI connector 20 fails, simply remove the failed connector and replace it with a new one connected to the original cable body 10. Similarly, if the cable body 10 fails, simply detach the cable body 10 from the HDMI connectors 20 at both ends and connect the new cable body 10 to the HDMI connectors 20 at both ends.

[0032] In some embodiments, the first portion 31 is a male connector and the second portion 32 is a female connector. The male connector is typically inserted into the female connector. The male connector is smaller in size than the female connector. Therefore, in this embodiment, the first portion 31 is used as the male connector, which allows the first portion 31 to be smaller in size and to pass through a hole with a smaller diameter. Of course, in other embodiments, the first portion 31 can also be the female connector and the second portion 32 can be the male connector.

[0033] In some embodiments, the connector 30 may be a locking connector 30. When the first part 31 and the second part 32 of the connector 30 are connected, the locking mechanism secures the connection between the first part 31 and the second part 32. Alternatively, in some embodiments, the HMDI connector 20 is provided with an anti-detachment structure. When the first part 31 and the second part 32 are connected, the anti-detachment structure acts on the first part 31 to prevent the first part 31 and the second part 32 from detaching on their own, thereby ensuring the stability of the connection between the first part 31 and the second part 32. The anti-detachment structure may be, for example, a micro screw, a snap-fit, or other similar structure.

[0034] In some embodiments, the signal lines in the cable body 10 are all coaxial cables, and the connector 30 is a coaxial connector. In this embodiment of the HDMI cable solution, by using coaxial cables for all signal lines in the cable body 10, the diameter of each signal line in the cable body 10 is reduced, significantly decreasing the outer diameter and volume occupied by the cable body 10. Furthermore, the connector 30 uses a coaxial connector that mates with the coaxial cable, resulting in a significant reduction in the size of the connector 30 and the first portion 31 of the connector 30. This significantly reduces the diameter of the smallest hole through which the first portion 31 can pass, thereby significantly reducing the diameter of the through-holes through which the HDMI cable of this embodiment can pass. Products using the HDMI cable of this embodiment require smaller through-hole diameters during cable routing, resulting in less space occupied by the through-holes.

[0035] like Figure 5 As shown, in some embodiments, the cable body 10 does not have a reserved line X14 corresponding to the reserved pin of the HDMI connector 20. Since the reserved pin is usually not used in the normal signal transmission of the HDMI cable, that is, the reserved line X14 in the cable body 10 is usually not used, and the reserved line X14 has no associated signal line. Therefore, in this embodiment, the reserved line X14 corresponding to the reserved pin in the cable body 10 is removed. This will not affect the normal signal transmission of the HDMI cable. Furthermore, by removing the reserved line X14 in the cable body 10, the number of signal lines in the cable body 10 is reduced by one, which reduces the wire diameter and volume of the cable body 10. At the same time, the cost of the reserved line X14 is saved, thus reducing the cost of the HDMI cable. In addition, the number of signal lines in the cable body 10 is reduced by one, which means that the number of pins in the connector 30 can be reduced by one. That is, the number of pins in the first part 31 is reduced by one, thereby reducing the size of the first part 31. The diameter of the smallest hole that the first part 31 can pass through is smaller, which further reduces the diameter of the through hole that the HDMI cable can pass through.

[0036] like Figure 4 and Figure 6As shown, in some embodiments, the HDMI cable body 10 does not include at least one of the following: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17. That is, the HDMI cable body 10 omits data 0 shield line X8 and / or data 1 shield line X5 and / or data 2 shield line X2 and / or clock shield line X11 and / or DDC / CEC ground line X17. Therefore, in this embodiment, the HDMI cable body 10 has 1 to 5 fewer signal lines, meaning the number of pins in the first part 31 of the connector 30 can be reduced by 1 to 5, further reducing the size of the first part 31 and further reducing the diameter of the smallest hole through which the first part 31 can pass, thereby further reducing the diameter of the through hole through which the HDMI cable can pass. Additionally, in this embodiment, the shielding layer of the coaxial cable is electrically connected to the outer shell of the first part 31 (which is a conductor, such as metal), and the outer shell of the first part 31 is electrically connected to the grounding pin of the PCB board 21. The outer shell of the first part 31 can be connected to the grounding pin of the PCB board 21 through the outer shell of the second part 32 (which is a conductor, such as metal). If the outer shell of the second part 32 is connected to the grounding pin on the PCB board 21, the outer shell of the first part 31 is connected to the outer shell of the second part 32 when the first part 31 is connected to the second part 32. Alternatively, a fixing pin can be provided on the outer shell of the first part 31. When the first part 31 is connected to the second part 32, the fixing pin directly contacts the grounding pin on the PCB board 21, so that the outer shell of the first part 31 is connected to the grounding pin on the PCB board 21. By connecting the shielding layer of the coaxial cable to the grounding pin on the PCB board 21, the shielding layer of the coaxial cable is shielded from external signals, ensuring that the signal transmitted on the center conductor of the coaxial cable is not interfered with. Thus, even after removing the data 0 shielding line X8 and / or data 1 shielding line X5 and / or data 2 shielding line X2 and / or clock shielding line X11 and / or DDC / CEC ground line X17 in the cable body 10, the accuracy and reliability of the HDMI cable signal transmission can still be ensured, and the performance of the HDMI cable signal transmission is not affected.

[0037] like Figure 4As shown, in some embodiments, the cable body 10 does not include the data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17; that is, the cable body 10 of the HDMI cable eliminates all five signal lines: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17. This embodiment reduces the number of signal lines in the cable body 10 by five, allowing for a reduction of five pins in the first part 31 of the connector 30, significantly reducing the size of the first part 31. This significantly reduces the diameter of the smallest hole through which the first part 31 can pass, thereby significantly reducing the diameter of the through-hole through which the HDMI cable can pass. Furthermore, because the number of signal lines in the cable body 10 is reduced by five, and the number of pins in the connector 30 is reduced by five, the cost of the HDMI cable is significantly reduced, and the wire diameter and volume occupied by the cable body 10 are also significantly reduced.

[0038] In some embodiments, connector 30 is a 14-pin coaxial connector, and the first part 31 of connector 30 has 14 pins. In this embodiment, the number of signal lines in the line body 10 can be the same as the number of pins in the first part 31 of connector 30 (for example, the number of signal lines in the line body 10 is also 14), and the number of pins in the first part 31 can also be greater than the number of signal lines in the line body 10 (for example, the number of signal lines in the line body 10 is 13). Each signal line of the line body 10 is connected to its corresponding pin (the pin of the first part 31).

[0039] like Figure 5As shown, in some embodiments, the total number of signal lines in line body 10 is 13. The 13 signal lines in line body 10 are: data 0 differential signal line (TMDS data 0+ line X7 and TMDS data 0- line X9), data 1 differential signal line (TMDS data 1+ line X4 and TMDS data 1- line X6), data 2 differential signal line (TMDS data 2+ line X1 and TMDS data 2- line X3), clock differential signal line (TMDS clock+ line X10 and TMDS clock- line X12), CEC line X13, SCL line X15, SDA line X16, power line X18, and hot-plug monitoring line X19. In this embodiment of the HDMI cable, the data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, DDC / CEC ground line X17, and reserved line X14 are omitted from the cable body 10. This reduces the number of signal lines in the cable body 10 by 6, resulting in a smaller wire diameter and smaller volume, thus lowering the cost of the HDMI cable. At the same time, the first part 31 of the connector 30 can have 6 fewer pins, resulting in a smaller size of the first part 31 and a smaller minimum aperture through which the HDMI cable can pass. Alternatively, the connector 30 can be a 14-pin coaxial connector, with one pin left unused in the first part 31.

[0040] like Figure 4 As shown, in some embodiments, the total number of signal lines in line body 10 is 14. The 14 signal lines in line body 10 are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line X13, SCL line X15, SDA line X16, reserved line X14, power line X18, and hot-plug monitoring line X19. That is, in this embodiment, data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17 are omitted from line body 10, but reserved line X14 is retained. That is, 5 signal lines are reduced in line body 10. The 14 signal lines in line body 10 are connected one-to-one with the pins of the first part 31 of the 14-pin coaxial connector.

[0041] Below are some examples of line bodies 10 with different numbers of signal lines:

[0042] like Figure 5As shown, in some embodiments, the total number of signal lines in line body 10 is 14. The 14 signal lines in line body 10 are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line X13, SCL line X15, SDA line X16, power line X18, hot-plug monitoring line X19, and data 0 shield line X8 or data 1 shield line X5 or data 2 shield line X2 or clock shield line X11 or DDC / CEC ground line X17 (in this embodiment). Figure 5 (This example only uses the data 0 shield line X8 as an example). That is, in the HMDI cable of this embodiment, the reserved line X14 and four of the following are eliminated from the cable body 10: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17. In other words, the cable body 10 has 5 fewer signal lines, with only 14 signal lines. The wire diameter and volume occupied by the cable body 10 are greatly reduced, the cost is greatly reduced, and the coaxial connector can also be 14-pin.

[0043] In some embodiments, the total number of signal lines in the line body 10 is 15. The 15 signal lines in the line body 10 are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line X13, SCL line X15, SDA line X16, power line X18, hot-plug monitoring line X19, and data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CE. Any two of ground wire X17 and reserved wire X14; that is, in the HMDI cable of this embodiment, reserved wire X14 and three of the following are removed from the cable body 10: data 0 shield wire X8, data 1 shield wire X5, data 2 shield wire X2, clock shield wire X11, and DDC / CEC ground wire X17. That is, the cable body 10 has 4 fewer signal lines, and the cable body 10 has only 15 signal lines. The coaxial connector can be selected with a number of pins not less than 15.

[0044] In some embodiments, the total number of signal lines in the cable body 10 is 16. The 16 signal lines in the cable body 10 are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line X13, SCL line X15, SDA line X16, power line X18, hot-plug monitoring line X19, and any three of the following: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, DDC / CEC ground line X17, and reserved line X14. That is, in the HMDI cable of this embodiment, the reserved line X14 and two of the following are omitted from the cable body 10: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17. In other words, the number of signal lines in the cable body 10 is reduced by 3, and the cable body 10 has only 16 signal lines. The coaxial connector can be selected with a number of pins not less than 16.

[0045] In some embodiments, the total number of signal lines in the cable body 10 is 17. The 17 signal lines in the cable body 10 are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line X13, SCL line X15, SDA line X16, power line X18, hot-plug monitoring line X19, and any four of the following: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, DDC / CEC ground line X17, and reserved line X14. That is, in the HMDI cable of this embodiment, the reserved line X14 and one of the following in the cable body 10 are omitted: data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and DDC / CEC ground line X17. That is, the number of signal lines in the cable body 10 is reduced by 2, and the cable body 10 has only 17 signal lines. The coaxial connector can be selected with a number of pins not less than 17.

[0046] In some embodiments, the total number of signal lines in the line body 10 is 18. The 18 signal lines in the line body 10 are: data 0 differential signal line, data 1 differential signal line, data 2 differential signal line, clock differential signal line, CEC line X13, reserved line X14, SCL line X15, SDA line X16, power line X18, hot-plug monitoring line X19, and data 0 shield line X8, data 1 shield line X5, data 2 shield line X2, clock shield line X11, and... Any four of the DDC / CEC ground wires X17; that is, in the HMDI cable of this embodiment, one of the following is removed from the cable body 10: data 0 shield wire X8, data 1 shield wire X5, data 2 shield wire X2, clock shield wire X11, and DDC / CEC ground wire X17, but the reserved wire X14 is retained. That is, one signal line is reduced in the cable body 10, and the cable body 10 has only 18 signal lines. The coaxial connector can be selected with a number of pins not less than 18.

[0047] This utility model also proposes an instrument or device that uses an HDMI cable to transmit high-definition video signals, such as a drone, an optoelectronic pod, or medical equipment. This instrument or device includes at least one of the aforementioned HDMI cables, the structure of which can be referred to in the above embodiments and will not be repeated here. Because this utility model's instrument or device adopts the technical solution of any of the above-described HDMI cable embodiments, it possesses at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be repeated here.

[0048] In some embodiments, the instrument is provided with a cable pass-through hole, through which the HDMI cable passes. The diameter of the cable pass-through hole is greater than the width of the first part 31 and less than the maximum width of the HDMI connector 20. That is, the HDMI cable is achieved by detaching the first part 31 of the connector 30 from the second part 32, separating the HDMI connector 20 from the cable body 10, allowing the first part 31 to pass through the cable pass-through hole with one end of the cable body 10, and then reconnecting the first part 31 that has passed through the cable pass-through hole to the second part 32 of the HDMI connector 20.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
