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] With the rapid development of technologies such as high-definition video, virtual reality, and 8K ultra-high-definition, the transmission volume of audio and video data has experienced explosive growth, placing increasingly higher demands on the performance of transmission interfaces. HDMI (High-Definition Multimedia Interface), as the mainstream audio and video transmission interface, has undergone multiple version iterations and has been widely used in consumer electronics, security monitoring, broadcasting, and other fields. The standard HDMI 2.1 connector, as the mainstream interface in the current market, is designed based on established transmission protocols and physical specifications, supporting a certain data transmission rate. According to current technical parameters, the maximum data rate of this type of connector is 12Gbps, corresponding to a maximum bandwidth of 48Gbps. This performance specification, in its initial release, met the transmission needs of 4K resolution video and multi-channel audio, promoting the popularization of high-definition audio and video technology for a period of time. However, with continuous technological advancements, market demands for audio and video transmission have changed significantly. On one hand, 8K ultra-high-definition video boasts a resolution of 7680×4320, with a data volume more than four times that of 4K video, placing higher demands on transmission bandwidth. On the other hand, the application of technologies such as high dynamic range (HDR) and high frame rates (e.g., 120fps) has further increased the amount of audio and video data transmitted. Furthermore, in scenarios such as virtual reality and augmented reality, not only is it necessary to transmit high-resolution video data, but also to simultaneously transmit large amounts of sensor data, posing stringent challenges to the real-time performance and transmission speed of interfaces. Given such market demand, the 48Gbps maximum bandwidth of conventional HDMI 2.1 connectors has gradually shown its limitations, failing to meet the needs of the aforementioned high-transmission scenarios and becoming a bottleneck restricting the application of related technologies and the development of the industry.

[0003] Therefore, developing a new type of connector that can overcome the limitations of existing transmission rates and bandwidth to meet the market's demand for high transmission performance has become an urgent technical problem to be solved in this field. Utility Model Content

[0004] The purpose of this application is to provide a high-definition multimedia connector that can increase the connector's anti-interference capability, thereby achieving high-performance transmission.

[0005] Specifically, this application provides a high-definition multimedia connector, including: an insulating housing; an upper contact terminal group disposed within the insulating housing; a lower contact terminal group disposed within the insulating housing and disposed opposite to the upper contact terminal group; and a middle partition disposed between the upper contact terminal group and the lower contact terminal group for increasing the anti-interference capability of the upper contact terminal group and the lower contact terminal group.

[0006] In one possible implementation, the partition plate has multiple openings, the positions of which correspond to the mating positions of the high-speed signal terminals provided in the upper contact terminal group and the lower contact terminal group.

[0007] In one possible implementation, the front end of the partition plate is provided with a plurality of contact protrusions, the plurality of contact protrusions including a first contact protrusion group facing the upper contact terminal group and a second contact protrusion group facing the lower contact terminal group.

[0008] In one possible implementation, the first contact protrusion group and the second contact protrusion group are misaligned.

[0009] In one possible implementation, the partition plate has a first protrusion on the side facing the upper contact terminal group and a second protrusion on the side facing the lower contact terminal group.

[0010] In one possible implementation, the upper contact terminal group is provided with an upper grounding terminal, and the first protrusion is welded to the upper grounding terminal to achieve interference contact; the lower contact terminal group is provided with a lower grounding terminal, and the second protrusion is welded to the lower grounding terminal to achieve interference contact.

[0011] In one possible implementation, the end of the partition extends behind the bend of the lower contact terminal group, and the distance between it and the bend of the lower contact terminal group is 0.5mm-1.5mm.

[0012] In one possible implementation, both the upper and lower contact terminal groups include four pairs of high-speed signal terminals; the heads of all terminals in both the upper and lower contact terminal groups are provided with a thinning structure along the thickness direction.

[0013] In one possible implementation, the thickness of the thinning structure does not exceed 0.12 mm.

[0014] In one possible implementation, it further includes: an upper molding member for covering the tail portion of the upper contact terminal group; and a lower molding member for covering the tail portion of the lower contact terminal group.

[0015] The high-definition multimedia connector provided according to the embodiments of this application has the following beneficial effects: 1. Precisely adapts to high-speed signal transmission, reducing signal transmission obstruction and interference. Multiple openings on the partition plate are precisely positioned to correspond to the mating positions of the high-speed signal terminals in the upper and lower contact terminal groups. This design provides reasonable space for the mating of high-speed signal terminals, preventing the partition plate from obstructing or hindering the transmission path of high-speed signals and ensuring smooth high-speed signal transmission. At the same time, the openings also reduce unnecessary contact between the partition plate and the high-speed signal terminals to a certain extent, lowering the risk of signal interference caused by contact and helping to maintain stable high-speed signal transmission. 2. Enhanced Connection Guidance and Contact Stability. The multiple contact protrusions at the front end of the partition are divided into a first contact protrusion group facing the first contact terminal group and a second contact protrusion group facing the second contact terminal group. These contact protrusions provide excellent guidance during connector mating, ensuring precise mating of the upper and lower contact terminal groups with their corresponding components and improving mating efficiency. Furthermore, the contact protrusions make contact with the upper and lower contact terminal groups, increasing the contact points between the partition and the terminal groups, thereby enhancing the connection stability between the partition and the upper and lower contact terminal groups, reducing shaking or displacement during the connection process, and providing structural support for stable signal transmission. 3. Improved grounding reliability and enhanced shielding effect. The first protrusion on the side of the middle partition facing the first contact terminal group and the second protrusion on the side facing the second contact terminal group can form reliable contact with the corresponding terminal groups. This protrusion design ensures a stable electrical connection between the middle partition and the upper and lower contact terminal groups. Especially in terms of grounding, it can effectively conduct away any electromagnetic interference that may be generated through the protrusion, enhancing the middle partition's shielding capability against electromagnetic signals, reducing signal crosstalk between the upper and lower contact terminal groups, and further ensuring the quality of high-definition multimedia signal transmission.

[0019] 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.

[0020] With the rapid development and innovative breakthroughs in information technology, the market demand for audio and video transmission has undergone revolutionary changes. Firstly, in terms of video resolution, the standard resolution of 8K ultra-high-definition video reaches an astonishing 7680×4320 pixels, with a single frame data volume of up to 33.2 million pixels, four times that of 4K video. This places unprecedentedly stringent demands on the bandwidth capacity of transmission systems. Secondly, in terms of video quality, High Dynamic Range (HDR) technology can present richer color levels and brightness ranges, while high frame rate technologies (such as 120fps or even 240fps) significantly improve the smoothness of motion. The application of these advanced technologies has significantly increased the total amount of audio and video data transmitted. More complexly, in emerging application scenarios such as Virtual Reality (VR) and Augmented Reality (AR), the system not only needs to transmit ultra-high-resolution video data streams in real time, but also needs to simultaneously process large amounts of data information generated from various sensors such as gyroscopes, accelerometers, and position trackers. This poses extremely stringent technical challenges to the real-time response capability and transmission rate of the interface. Faced with these ever-increasing demands for high-performance transmission, although the traditional HDMI 2.1 connector provides a theoretical maximum bandwidth of 48Gbps, its performance bottleneck has gradually been exposed in practical applications, making it difficult to meet the transmission requirements of composite scenarios such as 8K+HDR+high frame rate. This technical limitation is becoming a key bottleneck factor restricting the in-depth development and industrial upgrading of ultra-high-definition video, virtual reality and other related technologies.

[0021] The core objective of this application is to effectively address the shortcomings and defects in existing technologies. To this end, a high-definition multimedia connector has been specifically developed. The spacer, as a functional component within the high-definition multimedia connector, significantly enhances the connector's electromagnetic interference resistance in complex electromagnetic environments through its unique structural design and material selection. Simultaneously, it optimizes the signal transmission path, thereby ensuring stable signal integrity during high-speed data transmission. Ultimately, this achieves superior performance for the connector in high-bandwidth multimedia signal transmission scenarios such as 4K / 8K ultra-high-definition video and high-fidelity audio.

[0022] For details, please refer to Figures 1 to 5 (All connectors provided in this application are referenced) Figures 1 to 5 (The numbering is general). This application provides a high-definition multimedia connector, including: an insulating housing; an upper contact terminal group 2 disposed within the insulating housing; a lower contact terminal group 3 disposed within the insulating housing and disposed opposite to the upper contact terminal group 2; and a middle partition 4 disposed between the upper contact terminal group 2 and the lower contact terminal group 3 for increasing the anti-interference capability of the upper contact terminal group 2 and the lower contact terminal group 3.

[0023] In a specific example, the connector mainly consists of the following key components: First, an insulating shell made of insulating material, which not only has good mechanical strength but also effectively prevents electromagnetic interference; second, an upper contact terminal group 2 is located at the upper part of the inner side of the insulating shell, which is manufactured using a precision stamping process to ensure the stability of signal transmission; correspondingly, a lower contact terminal group 3 is located at the lower part of the inner side of the insulating shell, with the two groups of terminals arranged in a tiered manner to form a stable signal transmission channel; it is particularly noteworthy that a middle partition 4 is also provided between the upper contact terminal group 2 and the lower contact terminal group 3, which is made of high-performance shielding material, which can significantly enhance the isolation between the two groups of terminals, effectively improve the overall connector's anti-electromagnetic interference capability, and thus ensure the high-quality transmission of high-definition multimedia signals.

[0024] Furthermore, the design of the spacer 4 in this embodiment is not only for improving anti-interference capability, but also has other multiple functions. For example, the spacer 4 can help fix the positions of the upper contact terminal group 2 and the lower contact terminal group 3, ensuring their precise alignment inside the connector, thereby reducing signal loss due to poor contact. At the same time, the presence of the spacer 4 can also enhance the mechanical strength of the entire connector, enabling it to better protect the internal contact terminals from damage when subjected to external forces.

[0025] In terms of design, the shape and size of the spacer 4 have been carefully calculated to ensure sufficient shielding effect without increasing volume excessively. Furthermore, the fit between the spacer 4 and the insulating housing has been designed with thermal expansion coefficients in mind to avoid unnecessary stress during temperature changes, which could affect the connector's performance and lifespan.

[0026] In one possible implementation, the partition 4 has a plurality of openings 41, the positions of which correspond to the docking positions of the high-speed signal terminals in the upper contact terminal group 2 and the lower contact terminal group 3; wherein, the openings 41 are rectangular holes, the length of which is 80%-90% of the length of the corresponding high-speed signal terminal contact end A, and the width of which is 110%-130% of the length of the corresponding high-speed signal terminal contact end A.

[0027] In a specific example, the partition 4 has multiple openings 41 of specific shapes evenly distributed on its structure. The positions of these openings 41 are precisely designed to correspond one-to-one with the docking positions of the high-speed signal terminals configured in the upper contact terminal group 2 and the lower contact terminal group 3. In particular, the openings 41 adopt a rectangular structure design. The length of the rectangular opening is strictly calculated and controlled between 80% and 90% of the length of the corresponding high-speed signal terminal contact end A. This design ensures the stability of signal transmission and avoids excessive openings 41 from affecting structural strength. At the same time, the width of the rectangular opening is set within the range of 110% to 130% of the length of the corresponding high-speed signal terminal contact end A. This width design provides sufficient installation space for the terminals and ensures good electromagnetic shielding effect.

[0028] Furthermore, this precise aperture design effectively reduces electromagnetic interference and improves signal clarity and stability. The aspect ratio of the rectangular aperture is optimized to accommodate the size and shape of high-speed signal terminals, ensuring signal integrity and reliability during high-speed data transmission. In practical applications, this design can significantly enhance the performance of electronic devices, especially in situations requiring the processing of large amounts of data and high-speed communication.

[0029] In one possible implementation, the front end of the partition 4 is provided with a plurality of contact protrusions, the plurality of contact protrusions including a first contact protrusion group 42 facing the upper contact terminal group 2 and a second contact protrusion group 43 facing the lower contact terminal group 3.

[0030] In a specific example, the front end region of the partition 4 is specially designed with multiple contact protrusions arranged in an array. These contact protrusions can be divided into two groups according to their direction of action and functional characteristics: the first group of contact protrusions extends towards the upper contact terminal group 2, forming the first contact protrusion group 42; correspondingly, the second group of contact protrusions protrudes towards the lower contact terminal group 3, forming the second contact protrusion group 43. Through precise geometric arrangement design, these two groups of contact protrusions can form stable and reliable mechanical contact and electrical connection with the upper and lower contact terminal groups 3 respectively.

[0031] This design allows the partition 4 to provide additional contact support while fulfilling its isolation function, ensuring smooth current transfer from one terminal group to another. The cooperation of the first contact protrusion group 42 with the upper contact terminal group 2 ensures a smooth transition of current from the input terminal of the upper terminal group to the front end area of ​​the partition 4, while the second contact protrusion group 43 guides the current from this area to the output terminal of the lower contact terminal group 3. This structure not only improves the efficiency of current transmission but also enhances the stability and durability of the entire connection system.

[0032] Furthermore, the shape, size, and layout of each contact protrusion are designed to accommodate different electrical connection requirements and mechanical strength requirements. The surfaces of the contact protrusions undergo special treatments, such as gold or silver plating, to reduce contact resistance and improve corrosion resistance, thereby extending the service life of the equipment. Through this design, the partition 4 not only physically isolates the upper and lower contact terminal groups 3 but also optimizes electrical performance, ensuring the efficient and safe operation of the entire system.

[0033] In one possible implementation, the first contact protrusion group 42 and the second contact protrusion group 43 are misaligned.

[0034] In a specific example, the first contact protrusion group 42 and the second contact protrusion group 43 are arranged in a staggered manner. Specifically, the two groups of protrusions are staggered in spatial position, that is, each protrusion unit of the first group of protrusions is not on the same axis as the corresponding protrusion unit of the second group of protrusions, but is offset by a certain distance in a specific direction.

[0035] In one possible implementation, the middle partition 4 has a first protrusion 44 on the side facing the upper contact terminal group 2 and a second protrusion 45 on the side facing the lower contact terminal group 3.

[0036] In a specific example, the partition 4, as a key component connecting the upper and lower contact terminal groups 3, is designed with a specific elastic contact structure. Specifically, a first protrusion 44 is provided on the surface of the partition 4 facing the upper contact terminal group 2. This protrusion has a raised design to ensure a stable and reliable elastic contact with the upper contact terminal group 2. Simultaneously, a second protrusion 45 is also provided at a corresponding position on the side of the partition 4 facing the lower contact terminal group 3. This protrusion also has a raised design to maintain good contact with the lower contact terminal group 3. These two protrusion structures are symmetrically arranged and together constitute a complete elastic contact system.

[0037] This design allows the partition 4 to provide a certain amount of elastic pressure when in contact with the upper and lower contact terminal groups 3, ensuring a tight and stable contact. The first protrusion 44 and the second protrusion 45 not only enhance the physical connection between the partition 4 and the contact terminal groups, but also accommodate contact terminals of different sizes and shapes, providing a certain degree of fault tolerance. Furthermore, this elastic contact design helps reduce contact problems caused by mechanical vibration or thermal expansion and contraction, thereby improving the reliability and durability of the entire connection system.

[0038] In practical applications, the material selection and shape design of the first bump 44 and the second bump 45 need to be comprehensively considered based on factors such as the material properties of the contact terminals, current carrying capacity, and expected service life. Typically, these bumps are made of materials with good conductivity and a certain degree of elasticity, such as phosphor bronze and stainless steel, to ensure good electrical contact and sufficient mechanical strength. At the same time, the shape design of the bumps needs to balance contact area and pressure distribution to achieve optimal contact performance.

[0039] In one possible implementation, the upper contact terminal group 2 is provided with an upper grounding terminal, and the first protrusion 44 is welded to the upper grounding terminal to achieve interference contact; the lower contact terminal group 3 is provided with a lower grounding terminal, and the second protrusion 45 is welded to the lower grounding terminal to achieve interference contact.

[0040] In a specific example, the upper contact terminal group 2 is specifically configured with an upper grounding terminal, which is welded to the first protrusion 44. By precisely controlling the dimensional tolerances of both, the first protrusion 44 can be pressed into the upper grounding terminal with a certain amount of interference, thereby forming a stable and reliable mechanical interference contact. Similarly, the lower contact terminal group 3 is also provided with a lower grounding terminal, which is also welded to the second protrusion 45. Through similar dimensional control methods, it is ensured that the second protrusion 4515 can be embedded into the lower grounding terminal with an appropriate amount of interference, ultimately achieving a tight interference contact between the two. This dual grounding design, through the synergistic effect of the upper and lower contact terminal groups 322, can effectively improve the electrical performance and mechanical stability of the entire connection system.

[0041] Furthermore, this welding-based interference contact method ensures that there is no looseness or gap between the grounding terminal and the bulge in the electrical connection, thereby greatly reducing contact resistance and improving the efficiency and safety of current transmission. This design not only helps prevent poor contact problems caused by vibration or temperature changes, but also effectively suppresses electromagnetic interference, ensuring the purity and stability of signal transmission.

[0042] In practical applications, this welded interference contact design also offers excellent corrosion resistance because the tight contact reduces the intrusion of air and moisture, thus extending the service life of the electrical connection. Simultaneously, the increased contact area improves heat conduction efficiency, helping to better dissipate heat in high-current applications and preventing performance degradation or damage due to overheating.

[0043] During manufacturing, precise machining techniques and strict tolerance control are typically required to achieve accurate welding. This includes precise measurement of the inner diameters of the upper and lower grounding terminals, as well as precise control of the outer diameters of the first and second protrusions 44 and 45. These meticulous process steps ensure that each contact point achieves the designed interference level, thereby guaranteeing the performance consistency of the entire electrical connection system.

[0044] In one possible implementation, the end of the partition 4 extends behind the bend of the lower contact terminal group 3, and the distance between it and the bend of the lower contact terminal group 3 is 0.5mm-1.5mm.

[0045] In a specific example, the end of the partition 4 is designed with a special rearward-extending structure, the length of which ensures complete coverage and extension to the area behind the bend of the lower contact terminal group 3. Simultaneously, to ensure electrical safety and mechanical stability, a specific spacing is maintained between the end of the partition 4 and the bend of the lower contact terminal group 3, strictly controlled between 0.5 mm and 1.5 mm. This precise spacing design effectively prevents short-circuit risks and ensures reliable fit and operational stability of all components.

[0046] Furthermore, this spacing design takes into account the cumulative tolerance issues during the manufacturing process, ensuring that even minor dimensional deviations during manufacturing will not affect the overall performance and safety of the product. The carefully designed spacing effectively reduces electrical faults caused by poor or excessively tight contact, thereby improving the lifespan and reliability of the entire electronic device. In practical applications, this design can also adapt to temperature changes in different environments, avoiding additional stress caused by thermal expansion and contraction, further ensuring stable operation of the equipment under various working conditions.

[0047] In one possible implementation, both the upper contact terminal group 2 and the lower contact terminal group 3 include 4 pairs of high-speed signal terminals; the heads of all terminals in the upper contact terminal group 2 and the lower contact terminal group 3 are provided with a thinning structure along the thickness direction.

[0048] In a specific example, both the upper contact terminal group 2 and the lower contact terminal group 3 contain four pairs of contact terminals specifically designed for high-speed signal transmission. These terminals are arranged in pairs to support differential signal transmission. Specifically, all contact terminals in both the upper and lower contact terminal groups 2 and 3, including signal and ground terminals, have a thinning structure formed along the thickness direction of the terminal in their contact tip region. This thinning structure is formed through a precision stamping process, effectively reducing the overall thickness of the terminal while maintaining sufficient mechanical strength. This design not only facilitates a more compact connector layout but also ensures impedance matching requirements during high-speed signal transmission, improving signal integrity. Furthermore, the placement of this thinning structure is carefully designed within the terminal tip contact area, optimizing contact performance without compromising the overall strength of the terminal.

[0049] Furthermore, this thin-plate structure design also considers the durability and reliability of the contact terminals in practical applications. By reducing the thickness of the contact terminal head, contact resistance can be reduced, thereby reducing energy loss and heat generation during signal transmission. This design is particularly suitable for high-speed data transmission applications, where signal integrity and transmission efficiency are critical. In addition, the edges of the thin-plate structure are finely polished to ensure a smooth contact surface, reducing the possibility of wear and corrosion, thus extending the connector's lifespan.

[0050] In practical applications, the combined use of upper contact terminal group 2 and lower contact terminal group 3 provides a stable electrical connection, meeting the stringent requirements of high-speed data transmission equipment for signal quality and transmission speed. This design is not only applicable to specific industry standards but also possesses excellent versatility and scalability, allowing for customization and optimization to meet diverse application needs. Through this design, manufacturers can offer connector products that are both industry-standard compliant and competitive, satisfying the market's demand for high-performance connectivity solutions.

[0051] In one possible implementation, the thickness of the thinning structure does not exceed 0.12 mm.

[0052] In a specific example, the thickness of the flapper structure is strictly controlled, with a maximum thickness not exceeding 0.12 mm. This precise thickness specification ensures that the flapper structure meets specific functional requirements and usage demands, while guaranteeing its reliability and stability during application. By limiting the thickness to this precise range, the overall performance of the structure can be effectively optimized.

[0053] Furthermore, this thickness limitation also takes into account the flexibility and portability of the thinning structure in practical operation. Its ultra-thin design makes the structure more space-efficient, facilitating integration into various compact devices without affecting other device performance. At the same time, the 0.12 mm thickness also means that extremely high precision and process control are required during manufacturing to ensure that each thinning structure meets design standards, thereby guaranteeing the consistency of the final product's quality.

[0054] In one possible implementation, the connector provided in this application embodiment further includes: an upper molding member 5, which is used to cover the tail of the upper contact terminal group 2; and a lower molding member 6, which is used to cover the tail of the lower contact terminal group 3. In a specific example, the connector structure provided in this application embodiment also includes two important molding components: an upper molding component 5 and a lower molding component 6. The main function of the upper molding component 5 is to completely wrap around and cover the end portion of the upper contact terminal group 2, providing fixation and protection. Simultaneously, the corresponding lower molding component 6 is used to tightly cover the tail area of ​​the lower contact terminal group 3. These two molding components are tightly integrated with the contact terminal group through a precision injection molding process, effectively preventing displacement or deformation of the terminals during connection and enhancing the overall mechanical strength of the structure, ensuring the stability of signal transmission. This dual-molded component design considers both ease of assembly and product reliability and durability.

[0055] Furthermore, the design of the upper molded component 5 and the lower molded component 6 also takes into account the requirements for heat dissipation and insulation. The upper molded component 5 is typically made of a material with excellent thermal conductivity to effectively conduct heat away from the upper contact terminal group 2 during connector operation, thereby preventing performance degradation or damage due to overheating. Meanwhile, the lower molded component 6 is made of a material with good insulation properties to ensure that no short circuit or electric shock occurs at the tail of the lower contact terminal group 3 during electrical connection, thus ensuring user safety.

[0056] The high-definition multimedia connector provided according to the embodiments of this application has the following beneficial effects: 1. Precisely adapts to high-speed signal transmission, reducing signal transmission obstruction and interference. Multiple openings on the partition plate are precisely positioned to correspond to the mating positions of the high-speed signal terminals in the upper and lower contact terminal groups. This design provides reasonable space for the mating of high-speed signal terminals, preventing the partition plate from obstructing or hindering the transmission path of high-speed signals and ensuring smooth high-speed signal transmission. At the same time, the openings also reduce unnecessary contact between the partition plate and the high-speed signal terminals to a certain extent, lowering the risk of signal interference caused by contact and helping to maintain stable high-speed signal transmission. 2. Enhanced Connection Guidance and Contact Stability. The multiple contact protrusions at the front end of the partition are divided into a first contact protrusion group facing the first contact terminal group and a second contact protrusion group facing the second contact terminal group. These contact protrusions provide excellent guidance during connector mating, ensuring precise mating of the upper and lower contact terminal groups with their corresponding components and improving mating efficiency. Furthermore, the contact protrusions make contact with the upper and lower contact terminal groups, increasing the contact points between the partition and the terminal groups, thereby enhancing the connection stability between the partition and the upper and lower contact terminal groups, reducing shaking or displacement during the connection process, and providing structural support for stable signal transmission. 3. Improved grounding reliability and enhanced shielding effect. The first protrusion on the side of the middle partition facing the first contact terminal group and the second protrusion on the side facing the second contact terminal group can form reliable contact with the corresponding terminal groups. This protrusion design ensures a stable electrical connection between the middle partition and the upper and lower contact terminal groups. Especially in terms of grounding, it can effectively conduct away any electromagnetic interference that may be generated through the protrusion, enhancing the middle partition's shielding capability against electromagnetic signals, reducing signal crosstalk between the upper and lower contact terminal groups, and further ensuring the quality of high-definition multimedia signal transmission.
