Description

[Technical Field]

[0001] This application relates to the technical field of electronic devices, and in particular to high definition multimedia connectors. [Background technology]

[0002] High-Definition Multimedia Interface (HDMI®) is a fully digital audio and video transmission interface that is widely used in a variety of electronic devices, including set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio, and televisions. Its ability to simultaneously transmit uncompressed high-definition video signals and high-quality audio signals over a single cable greatly simplifies system installation, making it an important interface standard for digital televisions and consumer electronic devices.

[0003] With the rapid development of technology, users' demands for higher image quality and clarity of display devices are increasing. Television display sizes continue to expand, and screen resolutions continue to improve. This has led to a dramatic increase in the amount of data that needs to be transmitted via the HDMI® interface. To meet this demand, the transmission speed of the HDMI® interface has gradually increased, and currently requires a high-frequency transmission standard of 48 Gbps. However, conventional HDMI® interfaces face many challenges in their structural design. While their structure is relatively simple, the design of the terminal width, thickness, and plastic cutouts is often ad hoc, lacking in systematicity and precision. This ad hoc design merely attempts to achieve the high-frequency transmission requirement of 48 Gbps while ensuring process feasibility.

[0004] In actual applications, this design has had a number of adverse effects. For example, an inappropriately designed terminal size can cause impedance mismatch during signal transmission, resulting in signal reflection and attenuation, which can seriously affect the stability and reliability of 48Gbps high-frequency transmission. The inappropriate design of the plastic cutout not only fails to provide adequate physical protection and electromagnetic shielding for the internal wiring, but also leads to uneven material distribution, which can cause additional electromagnetic interference and further degrade signal transmission quality. Furthermore, a single structural design makes it difficult to adapt to diverse application scenarios and complex electromagnetic environments, limiting the application expansion of the HDMI® interface in higher-end devices and emerging fields.

[0005] From the above, it can be seen that the traditional HDMI interface structure can no longer meet the increasing needs for high-performance transmission and the requirements of diverse application scenarios. In order to adapt to the evolving technological trends of future electronic devices, an innovative HDMI interface structure design that improves signal stability, reliability, and interference resistance under 48Gbps high-frequency transmission conditions is urgently needed. Summary of the Invention [Problem to be solved by the invention]

[0006] The purpose of this application is to provide a high-resolution multimedia connector that can meet the needs of electronic devices to support high-frequency transmission of 96 Gbps and 12K / 60 Hz through structural improvements. [Means for solving the problem]

[0007] Specifically, the present embodiment includes: an insulating body; and terminals provided within the insulating body, the terminals including a plurality of sets of high-speed signal terminals, the high-speed signal terminals being arranged in a staggered pattern in two rows; the high-speed signal terminal is provided with a connection portion, a main body portion, a resilient arm portion, and a docking portion in this order, the resilient arm portion having a width dimension larger than the width dimension of the main body portion, and the insulating main body covering the main body portion; The insulating body has first holes that can accommodate multiple high-speed signal terminals at positions corresponding to each set of high-speed signal terminals, and the first holes expose corresponding portions of the main body, thereby providing a high-resolution multimedia connector.

[0017] The high-definition multimedia connector according to the embodiment of the present application has the following beneficial effects:

[0018] 1. Optimizing high-speed signal transmission performance The terminals are arranged in two rows in a staggered pattern, which reduces signal interference between adjacent terminals, providing a more stable, high-speed signal transmission environment and ensuring efficient transmission of high-resolution multimedia data (high-definition video, audio, etc.).

[0022] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below clearly and completely with reference to the drawings in the embodiments of the present application, but it is clear that the described embodiments are only a part of the embodiments of the present application, and are not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative efforts fall within the scope of protection of the present application.

[0023] The structural design of the currently widely used HDMI® interface has obvious shortcomings in meeting the high-speed data transmission needs of new electronic devices. With the rapid popularity of 8K ultra-high-definition video, high dynamic range (HDR) content, and immersive VR / AR applications, the performance bottleneck of the conventional interface at ultra-high transmission speeds of 48 Gbps and above is becoming increasingly evident. Existing solutions are unable to meet increasingly stringent technical requirements, particularly in maintaining signal integrity, suppressing electromagnetic interference, and ensuring stable transmission over long distances. Therefore, the development of a revolutionary HDMI® interface architecture is urgently needed. This design must focus on resolving key technical challenges, such as high-frequency signal attenuation, crosstalk interference, and impedance matching, to ensure excellent signal quality even at ultra-high speeds of 48 Gbps. Furthermore, the new interface must offer excellent backward compatibility and meet the mechanical strength and connection reliability needs of various application scenarios, thereby providing powerful technical support for the future development of fields such as display technology, gaming entertainment, and professional audio and video.

[0024] To achieve the above objectives, the embodiment of the present application provides a high-definition multimedia connector 100, the performance of which is compared with that of a conventional high-definition multimedia connector, as shown in Figure 3. The structural improvement meets the needs of electronic devices that support high-frequency transmission of 96 Gbps and 12K / 60 Hz.

[0025] Specifically, as shown in FIGS. 1 and 2 , an embodiment of the present application includes an insulating body 1 and two rows of terminals 20 arranged in a staggered pattern provided in the insulating body 1, the terminals 20 including a plurality of sets of high-speed signal terminals 2, the high-speed signal terminals 2 being provided with a connection portion 21, a main body portion 22, an elastic arm portion 23, and a docking portion 24 in that order, the insulating body 1 covering the main body portion 22, the insulating body 1 having first holes 3 opened at positions corresponding to each set of the high-speed signal terminals 2, each capable of accommodating a plurality of the high-speed signal terminals 2, the first holes 3 exposing a corresponding portion of the main body portion 22, A high-resolution multimedia connector (100) is provided in which the first hole (3) is provided at a position on the insulating body (1) corresponding to the main body portion (22) of the high-speed signal terminal (2), and the area of ​​the first hole (3) is configured to occupy 58% to 61% of the total area of ​​the insulating body (1).

[0026] In one embodiment, the high-definition multimedia connector mainly consists of two parts: an insulating body 1 made of high-quality insulating material; and two rows of terminals precisely arranged in a staggered pattern within the insulating body 1. Among these terminals, multiple sets of high-speed signal terminals 2 for high-speed signal transmission are provided. Each set of high-speed signal terminals 2 employs a unique four-stage structural design, including a connection section 21 for connecting to a circuit board, a main body section 22 serving as the main support section, an elastic arm section 23 providing elastic contact, and a docking section 24 for docking. The insulating body 1 completely covers and fixes the main body section 22 through an injection molding process. In terms of structural design, the insulating body 1 is provided with first holes 3 corresponding to the mounting positions of each set of high-speed signal terminals 2. These first holes 3 not only accommodate multiple high-speed signal terminals 2 simultaneously, but also cleverly expose portions of the corresponding main body section 22. This design not only ensures reliable fixation of the terminals but also contributes to optimizing signal transmission performance.

[0027] The position of the first hole 3 is carefully designed and accurately placed in a specific area of ​​the insulating body 1 corresponding to the body portion 22 of the high-speed signal terminal 2. This placement ensures stable and reliable signal transmission. The area of ​​the first hole 3 is precisely designed and optimized, and its size range is precisely designed to occupy 58% to 61% of the total area of ​​the insulating body 1. This ratio range is selected to strike an optimal balance between the requirements for structural strength and the needs for signal transmission performance.

[0028] Furthermore, the design of the first hole 3 in the embodiment of the present application has other advantages. For example, it allows heat to be dissipated from the exposed portion of the body portion 22 of the high-speed signal terminal 2, which in part helps to effectively dissipate heat generated during high-speed data transmission. Furthermore, the design of the first hole 3 facilitates accurate positioning and installation of the high-speed signal terminal 2 during the production process, improving overall production efficiency and product reliability.

[0029] In this embodiment, the elastic arm portion 23 of the high-speed signal terminal 2 is designed to be both strong and elastic, thereby ensuring stable contact pressure during connection and disconnection and reducing interference and loss during signal transmission. The docking portion 24 is also designed with compatibility with the corresponding device interface in mind, ensuring stable and reliable connection.

[0030] To further improve the quality of signal transmission, the high-speed signal terminal 2 in the embodiment of the present application may be plated with gold or silver to reduce contact resistance and improve signal transmission efficiency and corrosion resistance. Furthermore, the material selection for the insulating body 1 also takes into consideration flame retardancy and high temperature resistance, ensuring stable performance of the high-resolution multimedia connector even in harsh environments.

[0031] In one possible embodiment, a high-resolution multimedia connector 100 is provided, in which the first hole 3 is provided at a position on the insulating body 1 corresponding to the main body portion 22 of the high-speed signal terminal 2, and the area of ​​the first hole 3 is configured to occupy 58% to 61% of the total area of ​​the insulating body 1.

[0032] In one specific example, the position of the first hole 3 is designed and accurately placed in a specific region of the insulating body 1 corresponding to the body portion 22 of the high-speed signal terminal 2. This placement ensures the stability and reliability of signal transmission. The area of ​​the first hole 3 is precisely designed and optimized, and its size range is precisely designed to occupy 58% to 61% of the total area of ​​the insulating body 1. This ratio range is selected to strike an optimal balance between the requirements for structural strength and the needs for signal transmission performance.

[0033] In one possible embodiment, the length direction of the first holes 3 themselves is a first direction, and the first holes 3 are distributed at intervals in the main body portion 22 along the first direction.

[0034] In one example, the first holes 3 are arranged as follows: The direction extending along the length of the first holes 3 is defined as a first direction, i.e., the longitudinal direction of the first holes 3, which is the direction indicated by X in FIG. 1 . The distribution of these first holes 3 in the main body 22 is characterized by a regularly spaced arrangement. Specifically, the first holes 3 are evenly spaced along the first direction within the length of the main body 22. This arrangement not only ensures structural stability but also achieves the expected functional effects, allowing the first holes 3 to be arranged in a regular array on the main body 22 according to design requirements. By spacing the holes in this manner, signal transmission speed can be increased while maintaining communication capabilities.

[0035] In one possible embodiment, the width direction of the first hole 3 itself is the second direction, a rib 4 is provided between two adjacent first holes 3, and the length of the first hole 3 in the second direction is greater than the length of the rib 4 in the second direction.

[0036] In one specific example, the width direction of the first hole 3 itself is defined as the second direction, i.e., the lateral size direction perpendicular to the length direction of the first hole 3, which is the direction indicated by Y in Figure 1. Ribs 4 are designed between adjacent first holes 3 to provide reinforcement. These ribs 4 extend along the second direction and connect to adjacent first holes 3. The size of each first hole 3 in the second direction is larger than the size of its adjacent ribs 4 in the same direction. This difference in size increases the opening space of the first hole 3 in the second direction, creating a clear contrast in structural features. This design not only ensures the strength of the entire structure but also optimizes the functional space of the first holes. Improving the size of the first holes in this way reduces impedance and maximizes signal transmission efficiency.

[0037] In one possible embodiment, the width direction of the first holes 3 themselves is set to the second direction, and the size of the first holes 3 in the second direction is the same.

[0038] In one specific example, the key size parameter of the first hole 3 remains constant in this second direction (i.e., the axial direction perpendicular to the first direction). Specifically, the size values ​​measured at each point along this direction are completely consistent, achieved through precise processing and strict quality control. This design feature is extremely important. Not only does it ensure the uniformity of the size of the first hole structure in the second direction, eliminating possible size deviations, but more importantly, this uniform size distribution effectively ensures the continuity of the signal transmission path and ensures stable signal transmission efficiency. In practical applications, this design can avoid signal interruption and signal loss issues caused by size fluctuations. This is particularly important for high-frequency signal transmission systems.

[0039] In one possible embodiment, the width direction of the elastic arm portion 23 is larger than the width direction of the main body portion 22. In the embodiment of the present application, the width direction is the direction indicated by Y in FIG.

[0040] In one specific example, the width of the elastic arm portion 23 is designed to be larger than the width of the main body portion 22. Specifically, the elastic arm portion 23 is larger in the width direction perpendicular to the length direction, and this difference in design creates a clear contrast between the structures of the elastic arm portion 23 and the main body portion 22. This design increases the elasticity of the elastic arm portion 23, making it easier to dock with the terminal of the docking portion 24.

[0041] In one possible embodiment, the thickness of the docking portion 24 of the high-speed signal terminal 2 is 0.12 mm or less.

[0042] In one embodiment, the docking contact portion of the high-speed signal terminal 2 adopts an ultra-thin design structure, and through in-depth molding and optimization, its overall thickness is strictly controlled to 0.12 mm. This ultra-thin design not only ensures high-speed signal transmission, but also effectively reduces the overall volume of the high-definition multimedia connector. Furthermore, the special materials and process treatment ensure the mechanical strength and durability of the terminal, allowing it to maintain stable electrical connection characteristics even after long-term use.

[0043] Furthermore, the design of this ultra-thin docking section 24 also takes into consideration the requirements for signal integrity and electromagnetic compatibility (EMC). By optimizing the geometric shape and surface treatment technology of the high-speed signal terminals, the clarity of signal transmission and interference resistance are further improved. In practical applications, this design reduces signal attenuation, ensures the reliability of high-speed data transmission, and meets the strict standards of modern electronic devices for high-speed interfaces.

[0044] To achieve this ultra-thin thickness, experts in the industry use advanced precision processing techniques such as micromachining, laser cutting, and electrochemical etching. These techniques allow for precise control of the amount of material removed, allowing for the fine dimensions required for the design. The material selection for the docking section 24 is also important. Typically, alloy materials with excellent electrical conductivity and mechanical properties are selected to ensure the terminal can withstand repeated insertion and removal and current loads, even at such a thin thickness.

[0045] During production, thickness and quality control of these high-speed signal terminals 2 are particularly strict. High-precision measuring equipment is typically used to ensure that the thickness of each terminal is accurately controlled to within 0.12 mm. Furthermore, to ensure the terminals' long-term stability and reliability, a series of environmental and mechanical tests, including temperature cycle tests, vibration tests, and mating / unmating life tests, are conducted to ensure the terminals can maintain their performance even under a variety of harsh conditions.

[0046] In designing and manufacturing the high-speed signal terminal 2, those skilled in the art must also consider the thermal expansion coefficient of the terminal to ensure that changes in the terminal's physical size at different operating temperatures do not affect stable signal transmission. Therefore, the material selection and design of the docking portion 24 often need to match the thermal expansion coefficient of the circuit board material to reduce mechanical stress caused by temperature changes.

[0047] Furthermore, to further improve the efficiency and reliability of signal transmission, the docking portion 24 of the high-speed signal terminal 2 may also integrate advanced contact technologies such as a spring contact design, which provides stable contact pressure, maintains good contact even after long-term use, and reduces contact resistance, thereby reducing signal loss and heat generation.

[0048] During the assembly process, special attention must be paid to the docking area 24 of the high-speed signal terminal 2. The assembly process must be precise to ensure the terminal is properly docked to the circuit board or other connecting components. To improve production efficiency and assembly accuracy, manufacturers must use automated assembly equipment. Assembled terminals must also undergo rigorous visual inspection and functional testing to ensure each terminal meets the design specifications and performance requirements.

[0049] In one possible embodiment, the width of the main body portion 22 of the high-speed signal terminal 2 changes in a stepwise manner, and the width of the main body portion 22 of the high-speed signal terminal 2 narrows in a stepwise manner from the elastic arm portion 23 toward the connection portion 21.

[0050] In one embodiment, the lateral size of the main body portion 22 exhibits a stepwise change, gradually decreasing from the resilient arm connection region toward the connection end along the signal transmission direction. This stepped width structure allows the cross-sectional area of ​​the main body portion 22 to gradually decrease from the resilient arm portion 23 toward the connection portion 21, resulting in a distinct, stepped narrowing. This stepwise width change not only optimizes impedance matching in the signal transmission path, but also effectively reduces signal reflection and loss, ensuring the mechanical strength and stability of the entire terminal structure. This stepped width narrowing design allows the high-speed signal terminal 2 to meet the requirements for a compact layout while maintaining excellent electrical characteristics.

[0051] Furthermore, this stepped width design also takes into account the thermal expansion and mechanical stress issues of signal terminals in actual applications. High-speed signal terminals 2 generate heat during operation, which can cause material expansion. This stepped width design reduces internal stress caused by temperature changes, improving the reliability and service life of the terminals. Furthermore, this design allows different material thicknesses to be applied to different parts of the terminal, allowing the terminal to distribute stress more evenly when subjected to forces from different directions, reducing localized stress concentrations and improving overall mechanical properties.

[0052] The stepped width design also presents challenges in the manufacturing process. Accurately achieving this stepped change in width may require high-precision processing techniques such as CNC milling or laser cutting. These high-precision processing methods can ensure that the size and location of each step meets the design requirements, ensuring consistent performance of the high-speed signal terminal 2. The design may also require specific material selection to ensure the material maintains sufficient strength and good conductivity in the stepped narrowing areas.

[0053] In one possible embodiment, the insulating body 1 is provided with a fixing area 11 whose width is smaller than the width of the first hole 3 .

[0054] In one specific example, the lateral size of the fixing region 11 is precisely calculated so that its width is significantly smaller than the opening width of the corresponding first hole 3. This size difference effectively ensures an assembly gap between the terminal and the hole, facilitating the alignment operation during installation and ensuring structural stability after fixing. Specifically, the width of the fixing region 11 is typically 0.1 to 0.3 mm smaller than the width of the first hole 3. This precise size combination avoids interference problems during assembly and prevents excessive gaps from affecting the reliability of the connection.

[0055] Furthermore, this design takes into consideration the thermal expansion and contraction issues that may arise in actual applications. Because materials expand and contract with temperature changes, if the fixing area 11 and the hole fit too tightly, excessive stress may occur under extreme temperatures, affecting the terminal's service life and connection reliability. Therefore, by making the fixing area 11 slightly smaller than the width of the notched hole, this stress can be alleviated to some extent, allowing the high-speed terminal to maintain good performance and stability even in environments with large temperature fluctuations.

[0056] During manufacturing, it is extremely important to accurately process the fastening area 11 of the body 22 of the high-speed terminal. Typically, high-precision processing equipment and sophisticated process flows are required to ensure consistent sizes for each terminal. Furthermore, to further improve assembly convenience and reliability, the surface of the fastening area 11 can be specially treated, such as by adding a fine texture or coating to increase the coefficient of friction, thereby enhancing the fastening effect between the terminal and the hole without the need for additional fastening elements.

[0057] In practical applications, this high-speed terminal design enables fast and stable signal transmission, which is crucial for high-speed data communication equipment. For example, in high-speed data processing systems such as computers, servers, and network equipment, the performance of the terminals directly affects the overall operating efficiency and data transmission accuracy of the system. Therefore, optimizing the terminal design not only improves equipment performance, but also extends the equipment's service life and reduces maintenance costs.

[0058] In one possible embodiment, at the intersection of said fastening area 11 and said rib 4, a second hole 5 is provided.

[0059] In one example, in order to reduce the weight of the structure and improve material utilization, the designers provided an optimized second hole 5 structure at a specific location where the fixing area 11 and the rib 4 intersect and connect. This second hole 5 not only effectively reduces the overall weight, but also achieves a rational distribution of material while ensuring structural strength, thereby achieving the dual purpose of reducing weight without affecting functionality.

[0060] Furthermore, the carefully designed second hole 5 further optimizes the stress distribution within the component and reduces stress concentration, thereby improving the durability and reliability of the entire structure. This second hole design also reduces impedance, helping to improve the signal transmission speed of the terminal.

[0061] In one possible embodiment, the high-speed signal terminals 2 close to the edges of the insulating body 1 are not provided with ground terminals.

[0062] In one specific example, it was found that the high-speed signal terminals 2 located on the edge of the insulating body 1 adopt a special layout design, specifically, no corresponding ground terminals are arranged around these high-speed signal terminals 2. This design was selected after considering the signal transmission characteristics. Reducing the number of ground terminals optimizes the impedance matching of the high-speed signal transmission path and ensures signal quality. This layout also helps save space and simplify the overall structural design, especially in application scenarios with strict space requirements. However, although this design reduces the number of ground terminals, other measures must also be taken to ensure that it does not affect the electromagnetic compatibility of the system.

[0063] Furthermore, when implementing this design, it may be necessary to consider the interaction between the high-speed signal terminal and the insulating body 1 and their influence on the high-speed signal transmission performance. For example, the material selection for the insulating body 1 and the edge processing method can have a significant impact on the performance of the high-speed signal terminal. When selecting a material, factors such as its dielectric constant, dielectric loss tangent, and temperature stability must be considered so that the signal terminal can maintain stable transmission characteristics under various operating environments.

[0064] Regarding edge treatment, special process technology may be required to ensure smoothness and cleanliness of the edges to avoid signal interference caused by rough edges or burrs. Furthermore, to further optimize the transmission quality of high-speed signals, special electromagnetic shielding measures are designed in the edge area of ​​the insulating body 1 to reduce the influence of external electromagnetic interference on the signal terminals.

[0065] In practical applications, the implementation of this design must also comprehensively consider cost, manufacturing process complexity, and end product reliability. Therefore, those skilled in the art must conduct a series of experiments and simulation analyses to verify the effectiveness of the selected solution and maximize cost-effectiveness without sacrificing performance. Through these careful design considerations and optimizations, the end product can meet the expected performance standards for high-speed signal transmission while also satisfying market requirements for product reliability and cost-effectiveness.

[0066] The high-definition multimedia connector according to the embodiment of the present application has the following beneficial effects:

[0067] 1. Optimizing high-speed signal transmission performance The terminals are arranged in two rows in a staggered pattern, which reduces signal interference between adjacent terminals, providing a more stable, high-speed signal transmission environment and ensuring efficient transmission of high-resolution multimedia data (high-definition video, audio, etc.). A first hole is provided corresponding to each set of high-speed signal terminals, and a portion of the main body is exposed, thereby reducing the adverse effects of the insulating body on high-speed signals (signal attenuation, delay, etc.), and further improving the integrity and speed of signal transmission.

[0068] 2. Improved structural rationality and stability The insulating body covers the main body of the terminal, effectively fixing and protecting the terminal, improving the structural stability of the entire connector and reducing damage to the terminal caused by external vibrations and operations such as insertion and removal. The terminal is designed in stages (connection section, main body section, elastic arm section, and docking section). Each section has a clear function, and not only does it facilitate stable connection with external devices (connection section, docking section), but the elastic arm section can also adapt to changes in force during insertion and removal, extending the connector's lifespan.

[0069] 3. Meet the requirements of high-resolution multimedia applications In response to the high signal quality requirements of high-definition multimedia transmission, the connectors have been optimized in terms of terminal arrangement and insulating body structure to ensure stable support for high-speed, large-capacity data transmission, meet the requirements for scenarios such as high-definition video playback and multimedia device interconnection, and improve user experience.
