Description

Technical Field

[0001] This application relates to the field of electronic components technology, and in particular to a high-definition multimedia connector. Background Technology

[0002] High-Definition Multimedia Interface (HDMI), as a fully digital audio and video transmission interface, is widely used in various electronic devices such as set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio systems, and televisions. It can simultaneously transmit uncompressed high-definition video signals and high-quality audio signals in a single cable, greatly simplifying system wiring and becoming a key interface standard for digital televisions and consumer electronics products. With the rapid development of technology, users' demands for image quality and clarity in display devices are constantly increasing. Television display sizes are continuously growing, and screen resolutions are constantly improving, leading to an exponential increase in the amount of data that HDMI interfaces need to transmit. To meet this demand, the transmission speed of HDMI interfaces has been gradually improved, currently requiring a high-frequency 48Gbps transmission standard. However, existing conventional HDMI interfaces have revealed many problems in their structural design. Their structure is relatively simple, lacking systematic and precise design in the width, thickness, and plastic inserts of the terminals, often appearing rather arbitrary. This arbitrary design is merely to barely achieve the high-frequency 48Gbps transmission requirement under the basic premise of meeting manufacturing feasibility. In practical applications, this design approach has brought a series of negative consequences. For example, an unreasonable terminal size design may lead to impedance mismatch during signal transmission, resulting in signal reflection and attenuation, severely affecting the stability and reliability of high-frequency 48Gbps transmission. Improperly designed plastic casings not only fail to provide adequate physical protection and electromagnetic shielding for internal circuitry but may also introduce additional electromagnetic interference due to uneven material distribution, further degrading signal transmission quality. Furthermore, a single structural design struggles to adapt to diverse application scenarios and complex electromagnetic environments, limiting the application expansion of HDMI interfaces in more high-end devices and emerging fields. It is evident that the existing conventional HDMI interface structure can no longer meet the ever-increasing demands for high-performance transmission and the requirements of diverse application scenarios. There is an urgent need for an innovative HDMI interface structure design to improve its signal stability, reliability, and anti-interference capabilities under high-frequency 48Gbps transmission conditions, in order to adapt to the ever-evolving technological trends of future electronic devices. Utility Model Content

[0003] The purpose of this application is to provide a high-definition multimedia connector that, through structural improvements, can meet the requirements of 96Gbps high-frequency transmission and support 12K / 60Hz for electronic devices.

[0004] Specifically, this application provides a high-definition multimedia connector, including: an insulating body and terminals disposed within the insulating body. The terminals include multiple sets of high-speed signal terminals arranged in two staggered rows. Each high-speed signal terminal is sequentially provided with a connecting section, a main body section, a spring arm section, and a mating section. The spring arm section has a width dimension larger than the main body section's width dimension. The insulating body covers the main body section. The insulating body has a first cutout corresponding to the position of each set of high-speed signal terminals. The first cutout can accommodate a plurality of high-speed signal terminals and expose the corresponding portion of the main body section.

[0005] In one possible implementation, the first cutout is disposed on the insulating body at a position corresponding to the main body segment of the high-speed signal terminal, and the area of ​​the first cutout occupies 58% to 61% of the insulating body.

[0006] In one possible implementation, the first cutout is a first direction along its own length, and the first cutout is distributed at intervals along the first direction on the main body segment.

[0007] In one possible implementation, the first cutout has a second direction along its own width, and the size of the first cutout is the same along the second direction.

[0008] In one possible implementation, a rib is provided between two adjacent first holes, and the length of the first hole along the second direction is greater than the length of the rib along the second direction.

[0009] In one possible implementation, the thickness of the mating section of the high-speed signal terminal does not exceed 0.12 mm.

[0010] In one possible implementation, the width of the main body segment of the high-speed signal terminal varies in a stepped manner, narrowing in a stepped manner from the spring arm segment to the connecting segment.

[0011] In one possible implementation, the insulating body is provided with a fixing area, the width of which is smaller than the width of the first cutout.

[0012] In one possible implementation, a second cutout is provided at the intersection of the fixing area and the rib.

[0013] In one possible implementation, the high-speed signal terminal near the edge of the insulating body is not provided with a grounding terminal.

[0014] The high-definition multimedia connector provided according to the embodiments of this application has the following beneficial effects: 1. Optimize high-speed signal transmission performance: The terminals are arranged in two staggered rows, which reduces signal interference between adjacent terminals, provides a more stable environment for high-speed signal transmission, and ensures efficient transmission of high-definition multimedia data (such as high-definition video and audio).

[0015] Each set of high-speed signal terminals is provided with a first cutout to expose part of the main body section, which can reduce the adverse effects of the insulation body on high-speed signals (such as signal attenuation, delay, etc.) and further improve the integrity and speed of signal transmission.

[0016] 2. Improve structural rationality and stability: The insulating body covers the main body of the terminal, which can effectively fix and protect the terminal, enhance the overall structural stability of the joint, and reduce damage to the terminal caused by external vibration, insertion and removal operations, etc.

[0017] The terminal is designed in sections (connection section, main body section, spring arm section and docking section), with each section having a clear function. This facilitates stable connection with external equipment (connection section and docking section) and allows the spring arm section to adapt to changes in force during insertion and removal, thus extending the service life of the connector.

[0018] 3. Adapts to high-definition multimedia application requirements: To address the high signal quality requirements of high-definition multimedia transmission, the connectors are optimized in terms of terminal arrangement and insulation structure to ensure stable support for high-speed, high-capacity data transmission. This meets the needs of scenarios such as high-definition video playback and multimedia device interconnection, thereby enhancing the user experience. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The currently widely adopted conventional HDMI interface architecture has shown significant shortcomings in meeting the high-speed data transmission demands of next-generation electronic devices. With the rapid popularization of 8K ultra-high-definition video, high dynamic range (HDR) content, and immersive VR / AR applications, the performance bottleneck of traditional interfaces at ultra-high transmission rates of 48Gbps and above is becoming increasingly prominent, particularly in areas such as signal integrity maintenance, electromagnetic interference suppression, and stable long-distance transmission. Existing solutions struggle to meet increasingly stringent technical requirements. Therefore, there is an urgent need to develop a groundbreaking innovative HDMI interface architecture. This design must focus on solving 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 48Gbps. Simultaneously, the new interface must possess good backward compatibility and adapt to the mechanical strength and connection reliability requirements of different application scenarios, thereby providing solid technical support for the future development of display technology, gaming entertainment, and professional audio-visual fields.

[0024] To achieve the above objectives, embodiments of this application provide a high-definition multimedia connector, the performance of which is as follows: Figure 3 As shown, in contrast to the performance of existing high-definition multimedia connectors, it can meet the requirements of 96Gbps high-frequency transmission and support 12K / 60Hz electronic devices through structural improvements.

[0025] Specifically, such as Figures 1 to 2As shown, this application embodiment provides a high-definition multimedia connector, including: an insulating body 1 and two rows of staggered terminals disposed within the insulating body 1, the terminals including multiple sets of high-speed signal terminals 2; the high-speed signal terminals 2 are sequentially provided with a connecting section 21, a main body section 22, a spring arm section 23 and a docking section 24, the insulating body 1 covering the main body section 22; the insulating body 1 has a first aperture 3 corresponding to the position of each set of high-speed signal terminals 2, which can accommodate a plurality of high-speed signal terminals 2, the first aperture 3 exposing a portion of the corresponding main body section 22; The first hole 3 is disposed on the insulating body 1 at the position corresponding to the main body segment 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 insulating body 1.

[0026] In a specific example, the connector mainly consists of two parts: an insulating body 1 made of high-quality insulating material and two rows of terminals arranged in a staggered pattern, precisely positioned inside the insulating body 1. Among these terminals, multiple sets of high-speed signal terminals 2 are designed for high-speed signal transmission. Each set of high-speed signal terminals 2 adopts a unique four-segment structure design, including a connecting segment 21 for circuit board connection, a main body segment 22 as the main support, a spring arm segment 23 providing elastic contact, and a mating segment 24 for mating. The insulating body 1 completely encapsulates and fixes the main body segment 22 through injection molding. In terms of structural design, the insulating body 1 has first recesses 3 for the installation positions of each set of high-speed signal terminals 2. These first recesses 3 can not only accommodate multiple high-speed signal terminals 2 simultaneously but also cleverly expose a portion of the corresponding main body segment 22. This design ensures the stable fixation of the terminals and optimizes signal transmission performance. The first cutout 3 is meticulously designed and precisely positioned on the insulating body 1 in a specific area corresponding to the main body segment 22 of the high-speed signal terminal 2. This arrangement ensures the stability and reliability of signal transmission. The area of ​​the first cutout 3 has been rigorously calculated and optimized, with its size precisely configured to occupy between 58% and 61% of the total area of ​​the insulating body 1. This proportion balances structural strength requirements with signal transmission performance needs, achieving optimal equilibrium.

[0027] Furthermore, the first notch 3 design in this embodiment has other advantages. For example, it allows for heat dissipation in the exposed portion of the main body section 22 of the high-speed signal terminal 2, which effectively dissipates heat generated during high-speed data transmission. In addition, the notch design facilitates precise positioning and installation of the high-speed signal terminal 2 during production, thereby improving overall production efficiency and product reliability.

[0028] In this embodiment, the spring arm section 23 of the high-speed signal terminal 2 is designed to be both robust and flexible to ensure stable contact pressure during connection and disconnection, reducing interference and loss during signal transmission. Simultaneously, the design of the mating section 24 considers compatibility with corresponding device interfaces, ensuring the stability and reliability of the connection.

[0029] To further improve signal transmission quality, the high-speed signal terminal 2 in this embodiment may also include a plating treatment, such as a gold or silver plating, to reduce contact resistance and improve signal transmission efficiency and corrosion resistance. Furthermore, the material selection for the insulating body 1 also considers flame retardancy and high-temperature resistance to ensure stable connector performance even in harsh environments.

[0030] In one possible implementation, the first hole 3 is disposed on the insulating body 1 at a position corresponding to the main body segment 22 of the high-speed signal terminal 2, and the area of ​​the first hole 3 occupies 58% to 61% of the insulating body 1.

[0031] In a specific example, the first cutout 3 is precisely positioned on the insulating body 1 within a specific area corresponding to the main body segment 22 of the high-speed signal terminal 2. This arrangement ensures the stability and reliability of signal transmission. The area of ​​the first cutout is rigorously calculated and optimized, with its size precisely configured to occupy between 58% and 61% of the total area of ​​the insulating body 1. This proportion balances structural strength requirements with signal transmission performance needs, achieving optimal equilibrium.

[0032] In one possible implementation, the first hole 3 is positioned along its own length as a first direction, and the first hole 3 is distributed at intervals along the first direction on the main body segment 22.

[0033] In a specific example, the arrangement of the first cutouts 3 is as follows: the direction in which the cutout extends along its own length is defined as the first direction, i.e., the long axis direction of the first cutout 3. These first cutouts 3 are distributed on the main body segment 22 in a regular, spaced-apart pattern, specifically, each first cutout 3 maintains a uniform spacing along the first direction within the length of the main body segment 22. This arrangement ensures both structural stability and the desired functional effect, allowing the first cutouts 3 to form an orderly array on the main body segment 22 according to design requirements. Through this spaced-apart arrangement, signal transmission speed can be increased while maintaining communication capabilities.

[0034] In one possible implementation, the first hole 3 has a second direction along its own width, and a rib 4 is provided between two adjacent first holes 3. The length of the first hole 3 along the second direction is greater than the length of the rib 4 along the second direction.

[0035] In a specific example, the first cutout 3 is defined as the second direction along its width, i.e., the transverse dimension direction perpendicular to the length direction of the first cutout 3. Between two adjacent first cutouts 3, reinforcing ribs 4 are designed, extending along the second direction and connecting the adjacent first cutouts 3. It is worth noting that the dimension of the first cutout 3 in the second direction is larger than the dimension of the adjacent rib 4 in the same direction. This dimensional difference allows the first cutout 3 to have a larger opening space in the second direction, thus creating a significant structural feature contrast. This design ensures both the overall structural strength and optimizes the functional space of the cutouts. Through the above improvements in the cutout dimensions, impedance can be reduced, maximizing signal transmission efficiency.

[0036] In one possible implementation, the first hole 3 is in the second direction along its own width, and the size of the first hole 3 is the same along the second direction.

[0037] In a specific example, the key dimensional parameters of the first cutout 3 remain constant in this second direction (i.e., the axial direction perpendicular to the first direction). Specifically, the dimensional values ​​obtained at each measurement point along this direction are completely consistent, achieved through precise machining processes and strict quality control. This design feature is significant: it not only ensures the dimensional uniformity of the cutout structure in the second direction, eliminating potential dimensional deviations, but more importantly, this uniform dimensional distribution effectively guarantees the continuity of the signal transmission path, thereby ensuring the stability of signal transmission efficiency. In practical applications, this design can avoid signal interruptions or loss caused by dimensional fluctuations, which is particularly important for high-frequency signal transmission systems.

[0038] In one possible implementation, the dimension of the spring arm segment 23 along the width direction is larger than the dimension of the main body segment 22 along the width direction.

[0039] In a specific example, the spring arm segment 23 is designed to be wider than the corresponding width of the main body segment 22. Specifically, the spring arm segment 23 has a larger proportional dimension in the width direction perpendicular to the length direction. This design difference creates a striking contrast in structural form between the spring arm segment 23 and the main body segment 22. This design allows the spring arm segment 23 to have greater flexibility, facilitating the docking of the terminals of the docking segment 24.

[0040] In one possible implementation, the thickness of the mating section 24 of the high-speed signal terminal 2 does not exceed 0.12 mm. In a specific example, the mating contact section of the high-speed signal terminal 2 adopts an ultra-thin design structure, with its overall thickness strictly controlled to 0.12 mm after precise calculation and optimization. This ultra-thin design not only ensures high-speed signal transmission performance but also effectively reduces the overall size of the connector. At the same time, special materials and processes ensure the mechanical strength and durability of the terminal, enabling it to maintain stable electrical connection characteristics during long-term use.

[0041] Furthermore, this ultra-thin connector design also takes into account signal integrity and electromagnetic compatibility (EMC) requirements. By optimizing the terminal geometry and surface treatment technology, it further improves the clarity and interference resistance of signal transmission. In practical applications, this design can reduce signal attenuation, ensure the reliability of high-speed data transmission, and meet the stringent standards of modern electronic devices for high-speed interfaces.

[0042] To achieve this ultra-thin thickness, those skilled in the art employ advanced precision machining techniques, such as micromachining, laser cutting, or electrochemical etching. These techniques allow for precise control of material removal, thereby achieving the fine dimensions required by the design. Simultaneously, the material selection for the mating section 24 is also crucial; typically, alloy materials with good electrical conductivity and mechanical properties are chosen to ensure that the terminal can withstand repeated insertion and removal and current loads even at such a thin thickness.

[0043] During the production process, the thickness and quality control of these high-speed signal terminals 2 are particularly stringent. High-precision measuring equipment is typically used for inspection to ensure that the thickness of each terminal is precisely controlled within 0.12 mm. In addition, to ensure the long-term stability and reliability of the terminals, a series of environmental and mechanical tests are conducted, such as temperature cycling tests, vibration tests, and insertion / removal life tests, to ensure that the terminals maintain their performance under various extreme conditions.

[0044] When designing and manufacturing high-speed signal terminals 2, those skilled in the art can also consider the thermal expansion coefficient of the terminals to ensure that changes in the physical dimensions of the terminals at different operating temperatures do not affect the stable transmission of signals. Therefore, the material selection and design of the mating section 24 often need to match the thermal expansion coefficient of the circuit board material to reduce mechanical stress caused by temperature changes.

[0045] In addition, to further improve the efficiency and reliability of signal transmission, the mating section 24 of the high-speed signal terminal 2 may also integrate advanced contact technology, such as spring contact design. This design can provide stable contact pressure and maintain good contact even after long-term use, reducing contact resistance and thus reducing signal loss and heat generation.

[0046] During assembly, special attention is required to the mating section 24 of the high-speed signal terminal 2. To ensure correct mating of the terminal with the circuit board or other connecting components, the assembly process must be precise. Those skilled in the art need to use automated assembly equipment to improve production efficiency and assembly accuracy. Simultaneously, the assembled terminals must undergo rigorous visual inspection and functional testing to ensure that each terminal meets design specifications and performance requirements.

[0047] In one possible implementation, the width of the main body segment 22 of the high-speed signal terminal 2 varies in a stepped manner, with the width of the main body segment 22 of the high-speed signal terminal 2 narrowing in a stepped manner from the spring arm segment 23 to the connecting segment 21.

[0048] In a specific example, the lateral dimension of the main body segment 22 begins at the spring arm connection area and gradually decreases in a stepped manner towards the connection end along the signal transmission direction. This gradually narrowing width structure causes the cross-sectional area of ​​the main body segment 22 to decrease progressively from the spring arm segment 23 to the connection segment 21, forming a distinct stepped narrowing feature. This progressive width change not only optimizes the impedance matching of the signal transmission path but also effectively reduces signal reflection and loss, while ensuring the mechanical strength and stability of the overall terminal structure. Through this stepped narrowing design, the high-speed signal terminal 2 can meet the requirements of a compact space layout while maintaining excellent electrical performance.

[0049] Furthermore, this stepped width variation design also takes into account the thermal expansion and mechanical stress issues of the signal terminals in practical applications. Since the high-speed signal terminal 2 may generate heat during operation, causing material expansion, the stepped design helps alleviate internal stress caused by temperature changes, thereby improving the terminal's reliability and lifespan. In addition, this design allows for different material thicknesses to be applied to different parts of the terminal, enabling more even stress distribution when the terminal is subjected to forces in different directions, reducing localized stress concentration, and thus improving overall mechanical performance.

[0050] In terms of manufacturing processes, the stepped width design also presents challenges. To accurately achieve this gradual width, high-precision machining techniques, such as CNC milling or laser cutting, may be required. These high-precision machining methods ensure that the dimensions and position of each step meet design requirements, thereby guaranteeing the performance consistency of the high-speed signal terminal 2. Simultaneously, this design may also require specific material selection to ensure that the material maintains sufficient strength and good conductivity in the stepped narrowing area.

[0051] In one possible implementation, the insulated pump body 1 is provided with a fixing area 11, the width of which is smaller than the width of the first hole 3.

[0052] In a specific example, the lateral dimension of the fixing area 11 is precisely calculated to ensure that its width is significantly smaller than the opening width of the corresponding first notch 3. This dimensional difference design effectively ensures the assembly clearance between the terminal and the notch, facilitating alignment during installation and ensuring structural stability after fixing. Specifically, the width of the fixing area 11 is typically 0.1-0.3 mm smaller than the width of the first notch 3. This precise dimensional fit avoids interference during assembly and prevents excessive clearance from affecting connection reliability.

[0053] Furthermore, this design also takes into account the thermal expansion and contraction issues that may occur in practical applications. Since materials expand or contract with temperature changes, if the fit between the fixing area 11 and the cutout is too tight, it may lead to excessive stress under extreme temperature conditions, thereby affecting the terminal's service life and connection reliability. Therefore, by setting a fixing area 11 that is slightly smaller than the cutout width, this stress can be alleviated to some extent, ensuring that the high-speed terminal maintains good performance and stability even in environments with large temperature fluctuations.

[0054] During the manufacturing process, precise machining of the fixing area 11 of the high-speed terminal body segment 22 is crucial. This typically requires the use of high-precision machining equipment and meticulous processes to ensure dimensional consistency of each terminal. Furthermore, to further improve assembly convenience and reliability, the surface of the fixing area 11 can be specially treated, such as by adding minute textures or coatings, to increase the coefficient of friction, thereby enhancing the fixing effect between the terminal and the cutout without adding additional fixing components.

[0055] In practical applications, this high-speed terminal design provides 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 devices, the performance of the terminals directly affects the overall system's operating efficiency and the accuracy of data transmission. Therefore, optimizing the terminal design can not only improve equipment performance but also extend its lifespan and reduce maintenance costs.

[0056] In one possible implementation, a second cutout 5 is provided at the intersection of the fixing area 11 and the rib 4.

[0057] In a specific example, to improve structural lightweighting and material utilization, the designers incorporated an optimized second cutout structure 5 at a specific location where the fixed area 11 intersects with the ribs 4. This second cutout 5 not only effectively reduces the overall weight but also achieves a reasonable distribution of materials while ensuring structural strength, thus achieving the dual goals of reducing weight without compromising functionality.

[0058] Furthermore, the carefully designed second cutout 5 can further optimize the stress distribution of the component, reduce stress concentration, and thus improve the durability and reliability of the entire structure. This cutout design can also reduce impedance and help increase the signal transmission speed of the terminals.

[0059] In one possible implementation, the high-speed signal terminal 2 near the edge of the insulating body 1 is not provided with a grounding terminal.

[0060] In a specific example, the high-speed signal terminals 2 located at the edge of the insulating body 1 employ a unique layout design, specifically, no corresponding grounding terminals are configured around these high-speed signal terminals 2. This design choice is based on considerations of signal transmission characteristics; by reducing the number of grounding terminals, the impedance matching of the high-speed signal transmission path is optimized, thereby ensuring signal integrity. Simultaneously, this layout also helps save space and simplify the overall structural design, especially in applications with stringent space requirements. It is worth noting that although this design reduces the number of grounding terminals, other methods are still needed to ensure that the electromagnetic compatibility performance of the system is not affected.

[0061] Furthermore, implementing this design may require consideration of the interaction between the signal terminals and the insulating body 1, and their impact on high-speed signal transmission performance. For example, the material selection and edge treatment of the insulating body 1 can significantly affect the performance of the signal terminals. When selecting materials, factors such as dielectric constant, loss factor, and temperature stability need to be considered to ensure that the signal terminals maintain stable transmission characteristics under different operating environments.

[0062] In terms of edge processing, special processes may be required to ensure the smoothness and neatness of the edges, thereby avoiding signal interference caused by rough edges or burrs. Furthermore, to further optimize the transmission quality of high-speed signals, specific electromagnetic shielding measures will be designed in the edge area of ​​the insulating body 1 to reduce the impact of external electromagnetic interference on the signal terminals.

[0063] In practical applications, implementing this design requires comprehensive consideration of cost, manufacturing process complexity, and the reliability of the final product. Therefore, those skilled in the art need to conduct a series of experiments and simulation analyses to verify the effectiveness of the selected solution and ensure that cost-effectiveness is maximized without sacrificing performance. Through these meticulous design considerations and optimizations, it can be ensured that the final product achieves the expected performance standards in high-speed signal transmission while meeting market requirements for product reliability and cost-effectiveness.

[0064] The high-definition multimedia connector provided according to the embodiments of this application has the following beneficial effects: 1.

[0066] 2. Improve structural rationality and stability: The insulating body covers the main body of the terminal, which can effectively fix and protect the terminal, enhance the overall structural stability of the joint, and reduce damage to the terminal caused by external vibration, insertion and removal operations, etc.

[0067] The terminal is designed in sections (connection section, main body section, spring arm section and docking section), with each section having a clear function. This facilitates stable connection with external equipment (connection section and docking section) and allows the spring arm section to adapt to changes in force during insertion and removal, thus extending the service life of the connector.

[0068] 3.
