Description

Technical Field

[0001] This application relates to the technical field of electronic components, and particularly to connectors.

Background Art

[0002] With the rapid development of technologies such as high-definition video, virtual reality, and 8K ultra-high definition, the transmission volume of audio-video data has increased explosively, and the requirements for the performance of the transmission interface have become increasingly high. HDMI (High-Definition Multimedia Interface) has, as the current mainstream audio-video transmission interface, already gone through multiple iterations of versions and is widely applied in fields such as household electrical appliances, security monitoring, and broadcast television.

[0003] The conventional HDMI2.1 connector, as the mainstream interface form in the current market, can support a certain data transmission speed based on its structural design conforming to the established transmission protocol and physical specifications. According to the conventional technical parameters, the maximum data rate of this type of connector is 12 Gbps, and the corresponding maximum bandwidth is 48 Gbps. This performance index could meet the transmission needs of 4K resolution videos, multi-channel audio, etc. at the initial stage of its release and promoted the popularization of high-resolution audio-video technologies within a certain period.

[0004] However, with the continuous advancement of technology, the market's needs for audio-video transmission are changing significantly. On the one hand, the resolution of 8K ultra-high-definition video reaches 7680 x 4320, and its data volume is more than four times that of 4K video, presenting higher requirements for transmission bandwidth. On the other hand, the application of technologies such as high dynamic range (HDR) and high frame rates (e.g., 120fps) further increases the amount of audio-video data that needs to be transmitted. In addition, in scenes such as virtual reality and augmented reality, it is not only necessary to transmit high-resolution video data, but also to transmit large amounts of sensor data synchronously, which presents a serious challenge to the real-time capabilities and transmission rates of interfaces.

[0005] Given these market needs, the maximum bandwidth of standard HDMI 2.1 connectors, 48 ​​Gbps, is gradually showing its limitations, failing to meet the needs of the high-transmission scenarios mentioned above and becoming a bottleneck that restricts the application and industrial development of related technologies.

[0006] Therefore, in order to meet the market need for high transmission performance, developing new connectors that can overcome the limitations of existing transmission rates and bandwidths has become an urgent technical problem to be solved in this field. [Overview of the project]

[0007] The objective of this application is to provide a connector that can improve interference resistance and further achieve high-performance transmission.

[0008] Embodiments of this application provide a connector. The connector includes an insulating housing, a group of upper contact terminals provided within the insulating housing, a group of lower contact terminals provided within the insulating housing and facing the group of upper contact terminals, and a separator provided between the group of upper contact terminals and the group of lower contact terminals and configured to improve interference resistance between the group of upper contact terminals and the group of lower contact terminals.

[0009] In one possible implementation, the separator has a plurality of openings, the positions of which correspond to the docking positions with the high-speed signal terminals located in the upper contact terminal group and the lower contact terminal group.

[0010] In one possible implementation, the tip of the separator is provided with a plurality of contact protrusions, the plurality of contact protrusions including a first group of contact protrusions toward the upper group of contact terminals and a second group of contact protrusions toward the lower group of contact terminals.

[0011] In one possible implementation, the first group of contact protrusions and the second group of contact protrusions are offset from each other.

[0012] In one possible implementation, the separator is provided with 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.

[0013] In one possible implementation, an upper grounding terminal is provided in the upper contact terminal group, and the first protrusion is welded to the upper grounding terminal to achieve interference contact. A lower grounding terminal is provided in the group of lower contact terminals, and the second protrusion is welded to the lower grounding terminal, thereby achieving interference contact.

[0014] In one possible implementation, the end of the separator extends to the rear of the bent section of the lower contact terminal group, and the distance between it and the bent section of the lower contact terminal group is 0.5 mm to 1.5 mm.

[0015] In one possible implementation, both the upper contact terminal group and the lower contact terminal group include four pairs of high-speed signal terminals. The heads of all signal terminals in the upper and lower contact terminal groups are provided with a thinning structure that is aligned with the thickness direction.

[0016] In one possible implementation, the thickness of the thinned structure is 0.12 mm or less.

[0017] In one possible implementation, the connector is An upper molded part for covering the tail portion of the upper contact terminal group, The present invention further includes a lower molded part for covering the tail portion of the lower contact terminal group.

[0018] The connector according to the embodiment of this application has the following beneficial effects. 1. Precisely adapted to high-speed signal transmission, reducing signal transmission obstruction and interference. The multiple openings in the separator are precisely positioned to correspond to the docking locations of the high-speed signal terminals in the upper and lower contact terminal groups. This design provides a reasonable space for docking the high-speed signal terminals, preventing the separator from obstructing or hindering the high-speed signal transmission path and ensuring smooth high-speed signal transmission. At the same time, the presence of the openings reduces unnecessary contact between the separator and the high-speed signal terminals to some extent, reducing the risk of signal interference due to contact and contributing to the maintenance of stable high-speed signal transmission. 2. Improve connection guidance and contact stability. The multiple contact protrusions at the front end of the separator are divided into a first group of contact protrusions that face the first group of contact terminals and a second group of contact protrusions that face the second group of contact terminals. These contact protrusions provide good guidance during the connector docking process, guiding the upper and lower contact terminal groups to dock accurately with the corresponding members, thereby improving docking efficiency. In addition, the contact of the contact protrusions with the upper and lower contact terminal groups increases the number of contact points between the separator and the terminal groups, improving connection stability between the separator 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. Improve grounding reliability and enhance shielding effect. The first protrusion on the side of the separator facing the first group of contact terminals and the second protrusion on the side facing the second group of contact terminals can reliably contact the corresponding terminal groups. Such a protrusion design ensures that a stable electrical connection is established between the separator and the upper and lower groups of contact terminals. In particular, in terms of grounding, it can effectively conduct any electromagnetic interference to the outside through the protrusion, increasing the shielding capability of the separator against electromagnetic signals, reducing signal crosstalk between the upper and lower groups of contact terminals, and further ensuring the transmission quality of high-definition multimedia signals.

[Modes for carrying out the invention]

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application by referring to the drawings in the embodiments of this application. It is obvious that the described embodiments are only part of the embodiments of this application and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of this application.

[0022] With the rapid development and innovation progress of information technology, the market needs for audio-video transmission have already shown a revolutionary change trend. First, in terms of video resolution, the standard resolution of 8K ultra-high-definition video has reached an astonishing 7680×4320 pixels, and the data volume of a single frame of it is as high as 33.2 million pixels, which is 4 times that of 4K video. This has put extremely stringent requirements on the bandwidth capacity of the transmission system that are unprecedented. Second, in terms of video quality, high dynamic range (HDR) technology can show richer color levels and brightness ranges, and high frame rate technology (such as 120fps and then 60fps) can greatly improve the smoothness of videos. The application of these advanced technologies all significantly increase the total volume of audio-video data transmission. What is more complicated is that in new 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 synchronously process a large amount of data information generated by various sensors such as gyroscopes, accelerometers, and position trackers. This has posed extremely stringent technical challenges to both the real-time responsiveness and transmission rate of the interface. Facing these increasing high-performance transmission needs day by day, the conventional HDMI2.1 connector provides a theoretical maximum bandwidth of 48Gbps, but performance bottlenecks gradually appear in actual applications, making it difficult to meet the transmission requirements of composite scenarios such as 8K+HDR+high frame rate. Such technical limitations have become an important bottleneck element restricting the in-depth development and industrial upgrade of related technologies such as ultra-high-definition video and virtual reality

[0023] The main purpose of the embodiments of this application is to effectively solve the deficiencies and defects existing in the prior art. Therefore, a connector is specifically developed. As an internal functional component of the connector, the separator can significantly enhance the electromagnetic interference resistance performance of the connector in a complex electromagnetic environment and optimize the signal transmission path through its unique structural design and material selection. Thereby, it ensures the stable signal integrity of the connector during the high-speed data transmission process and finally realizes the excellent performance of the connector in broadband multimedia signal transmission scenarios such as 4K / 8K ultra-high-definition video and high-fidelity audio.

[0024] Specifically, referring to FIGS. 1 to 5 (for the connector according to this application, all refer to FIGS. 1 to 5, and their reference signs are general), the embodiments of this application provide a connector, including an insulating housing, an upper contact terminal group 2 provided in the insulating housing, a lower contact terminal group 3 provided in the insulating housing and opposite to the upper contact terminal group 2, and a separator 4 provided between the upper contact terminal group 2 and the lower contact terminal group 3 and used to improve the interference resistance between the upper contact terminal group 2 and the lower contact terminal group 3.

[0025] In one specific example, the connector is mainly composed of the following several important components. First, an insulating housing made of an insulating material, which not only has good mechanical strength but can also effectively prevent electromagnetic interference. Next, an upper contact terminal group 2 is provided at the upper position inside the insulating housing. The terminal group is manufactured by a precision pressing process to ensure the stability of signal transmission. The lower contact terminal group 3 provided below the inside of the insulating housing corresponds to it, and the two sets of terminals are distributed in a stepped manner to form a stable signal transmission path. It should be particularly noted that a separator 4 is further provided between the upper contact terminal group 2 and the lower contact terminal group 3. The separator 4 is made of a high-performance shielding material, which significantly enhances the separation degree between the two sets of terminals and effectively improves the electromagnetic interference resistance ability of the entire connector, thereby ensuring the high-quality transmission of high-definition multimedia signals.

[0026] Furthermore, the design of the separator 4 in the embodiment of this application has multiple functions in addition to improving interference resistance. For example, the separator 4 contributes to fixing the positions of the upper contact terminal group 2 and the lower contact terminal group 3, ensuring their precise alignment within the connector, thereby reducing signal loss due to poor contact. At the same time, the presence of the separator 4 also improves the overall mechanical strength of the connector, providing better protection for the internal contact terminals from damage when subjected to external forces.

[0027] In terms of design, the shape and size of separator 4 are carefully calculated to ensure sufficient shielding effect without increasing the volume excessively. Furthermore, the design of the separator 4 and the insulating housing takes into account the matching of thermal expansion coefficients to avoid the generation of unnecessary stress during temperature changes, which would affect the performance and lifespan of the connector.

[0028] In one possible implementation, the separator 4 has a plurality of openings 41, the positions of which correspond to the docking positions with the high-speed signal terminals located in the upper contact terminal group 2 and the lower contact terminal group 3, the openings 41 being rectangular, the length of which is 80% to 90% of the length of the contact end A of the corresponding high-speed signal terminal, and the width of which is 110% to 130% of the length of the contact end A of the corresponding high-speed signal terminal.

[0029] In one specific example, the structure of the separator 4 has multiple openings 41 of a specific shape uniformly distributed, and the positions of these openings 41 are precisely designed to form a one-to-one correspondence with the docking positions of the high-speed signal terminals located in the upper contact terminal group 2 and the lower contact terminal group 3. In particular, the openings 41 adopt a rectangular structure design, and the length of the rectangular openings is precisely calculated and controlled to 80% to 90% of the length of the contact end A of the corresponding high-speed signal terminals. Such a design ensures the stability of signal transmission and avoids excessive openings 41 affecting structural strength. At the same time, the width of the rectangular openings is set within the range of 110% to 130% of the length of the contact end A of the corresponding high-speed signal terminals. Such a width design provides sufficient mounting space for the terminals and ensures a good electromagnetic shielding effect.

[0030] Furthermore, the precise design of the opening 41 effectively reduces electromagnetic interference and improves the clarity and stability of signal transmission. The aspect ratio of the rectangular opening is optimized to suit the size and shape of the high-speed signal terminal, ensuring signal integrity and reliability during high-speed data transmission. In practical applications, such a design can significantly improve the performance of electronic equipment, especially when processing large amounts of data and high-speed communication is required.

[0031] In one possible implementation, the front end of the separator 4 is provided with a plurality of contact protrusions, the plurality of contact protrusions including a first group of contact protrusions 42 toward the upper contact terminal group 2 and a second group of contact protrusions 43 toward the lower contact terminal group 3.

[0032] In one specific example, the tip region of the separator 4 is specially designed and provided with multiple contact projection structures arranged in an array. These contact projections are divided into two groups according to their direction of action and functional characteristics. The first group of contact projections extends toward the upper contact terminal group 2 to form the first contact projection group 42, and correspondingly, the second group of contact projections protrudes toward the lower contact terminal group 3 to form the second contact projection group 43. Through precise geometric arrangement design, these two groups of contact projections can form stable and reliable mechanical contact and electrical connection with the upper contact terminal group 2 and the lower contact terminal group 3, respectively.

[0033] This design allows the separator 4 to achieve its isolation function while also providing additional contact support, ensuring smooth transmission of current from one group of terminals to the other. The cooperation of the first group of contact protrusions 42 and the upper group of contact terminals 2 ensures that the current smoothly transitions from the input terminals of the upper group of terminals to the tip region of the separator 4, and the second group of contact protrusions 43 guides the current from this region to the output terminals of the lower group of contact terminals 3. This structure not only improves the efficiency of current transmission but also enhances the stability and durability of the entire connection system.

[0034] Furthermore, the shape, size, and layout of each contact protrusion are designed to accommodate different electrical connection needs and mechanical strength requirements. The surface of the contact protrusions is treated with special processes such as gold or silver plating to reduce contact resistance and improve corrosion resistance, thereby extending the service life of the equipment. With this design, the separator 4 not only physically isolates the upper contact terminal group 2 and the lower contact terminal group 3, but also optimizes electrical performance and ensures the efficient and safe operation of the entire system.

[0035] In one possible implementation, the first contact projection group 42 and the second contact projection group 43 are offset from each other.

[0036] In one specific example, the first group of contact protrusions 42 and the second group of contact protrusions 43 are arranged in a offset manner, specifically, the protrusions of the two groups are arranged to form an alternating distribution in spatial position, that is, each protrusion unit of the first group of protrusions and the corresponding protrusion unit of the second group of protrusions are not located on the same axis, but are offset by a certain distance along a specific direction.

[0037] In one possible implementation, the separator 4 is provided with 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.

[0038] In one specific example, the separator 4, as a key component connecting the upper contact terminal group 2 and the lower contact terminal group 3, is designed to have a specific elastic contact structure. Specifically, a first protrusion 44 is provided on the surface of the separator 4 facing the upper contact terminal group 2. The protrusion's design ensures stable and reliable elastic contact with the upper contact terminal group 2. Simultaneously, a second protrusion 45 is provided on the opposite side of the separator 4 facing the lower contact terminal group 3. This protrusion also employs a protrusion design and is used 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.

[0039] This design allows the separator 4 to provide a constant elastic pressure when in contact with the upper and lower contact terminal groups 3, ensuring tight contact and stability. The placement of the first and second protrusions 44 and 45 not only strengthens the physical connection between the separator 4 and the contact terminal groups, but also allows for adaptation to contact terminals of different sizes and shapes, providing a certain tolerance. Furthermore, this elastic contact design contributes to reducing contact failure problems caused by factors such as mechanical vibration or thermal expansion and contraction, thereby improving the reliability and durability of the entire connection system.

[0040] In actual applications, the material selection and shape design of the first protrusion 44 and the second protrusion 45 must be comprehensively considered in accordance with factors such as the material properties of the contacting terminals, current load capacity, and expected service life. Typically, these protrusions are manufactured from materials with good conductivity and a certain degree of elasticity, such as phosphor bronze or stainless steel, to ensure good electrical contact and sufficient mechanical strength. At the same time, the shape design of the protrusions must take into account the contact area and pressure distribution to achieve the optimal contact effect.

[0041] 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, thereby achieving 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, thereby achieving interference contact.

[0042] In one specific example, the upper contact terminal group 2 is equipped with an upper grounding terminal, and a welding connection method is used between the upper grounding terminal and 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 constant amount of interference, thereby forming a stable and reliable mechanical interference contact. Similarly, the lower contact terminal group 3 is equipped with a corresponding lower grounding terminal, and a welding connection method is used between the lower grounding terminal and the second protrusion 45. Similar dimensional control means are used to ensure that the second protrusion 45 can be fitted into the lower grounding terminal with an appropriate amount of interference, ultimately achieving a tight interference contact between the two. Such a double grounding design, through the cooperative action of the upper contact terminal group 2 and the lower contact terminal group 3, can effectively improve the electrical performance and mechanical stability of the entire connection system.

[0043] Furthermore, this welding interference contact method ensures that there is no looseness or gap between the ground terminal and the protrusion in the electrical connection, thereby significantly reducing contact resistance and improving the efficiency and safety of current transmission. Such a design not only helps prevent contact failure problems due to vibration or temperature changes, but also effectively suppresses electromagnetic interference, ensuring the cleanliness and stability of signal transmission.

[0044] In practical applications, such weld interference contact designs offer superior corrosion resistance because close contact reduces the intrusion of air and moisture, thereby extending the service life of electrical connections. Simultaneously, the increased contact area improves thermal conductivity, contributing to better heat dissipation in high-current applications and preventing performance degradation or damage due to overheating.

[0045] In the manufacturing process, precise machining techniques and strict tolerance control are typically required to achieve accurate welding. This includes accurately measuring the inner diameter dimensions of the upper and lower grounding terminals and precisely controlling the outer diameter dimensions of the first and second protrusions 44 and 45. These meticulous process steps ensure that each contact point reaches the interference amount required by the design, thereby guaranteeing consistent performance across the entire electrical connection system.

[0046] In one possible implementation, the end of the separator 4 extends to the rear of the bent section of the lower contact terminal group 3, and the distance between it and the bent section of the lower contact terminal group 3 is 0.5 mm to 1.5 mm.

[0047] In one specific example, the end of the separator 4 is designed with a special structure that extends backward, ensuring that its extension length completely covers the area behind the bent portion of the lower contact terminal group 3. At the same time, to ensure electrical safety and mechanical stability, a specific spacing range is maintained between the end of the separator 4 and the bent segment of the lower contact terminal group 3, and this spacing is strictly controlled between 0.5 mm and 1.5 mm. Such a precise spacing design not only effectively prevents the risk of short circuits but also ensures secure mating and operational stability of each component.

[0048] Furthermore, setting such spacing takes into account the problem of cumulative tolerances during the production process, ensuring that even slight dimensional variations during manufacturing do not affect the overall integrity and safety of the product. Precisely designed spacing effectively reduces electrical failures due to poor contact or over-contact, thereby improving the service life and reliability of the entire electronic equipment. In practical applications, such a design can also adapt to temperature changes in different environments, avoiding extra stress due to thermal expansion and contraction, and further ensuring stable operation of the equipment under various operating conditions.

[0049] In one possible implementation, both the upper contact terminal group 2 and the lower contact terminal group 3 include four pairs of high-speed signal terminals, and the heads of all terminals in both the upper contact terminal group 2 and the lower contact terminal group 3 are provided with a thinning structure along the thickness direction.

[0050] In one specific example, the upper contact terminal group 2 and the lower contact terminal group 3 each include four pairs of contact terminals dedicated to high-speed signal transmission, arranged in pairs to support differential signal transmission. In particular, all contact terminals in the upper contact terminal group 2 and the lower contact terminal group 3 include signal terminals and ground terminals, each having a thinning structure machined along the thickness direction of the terminal in the head area of ​​the contact end. Such a thinning structure is formed by precision press working and effectively reduces the overall thickness of the terminal while maintaining sufficient mechanical strength. This structural design is advantageous not only for realizing a more compact connector layout but also for ensuring impedance matching requirements during high-speed signal transmission and improving signal integrity. Furthermore, such a thinning structure can be installed in a carefully designed location within the contact area of ​​the terminal head, not only without affecting the overall strength of the terminal but also by optimizing contact performance.

[0051] Furthermore, this thin-profile design takes into account the durability and reliability of the contact terminals during actual application. By reducing the thickness of the contact terminal heads, contact resistance can be reduced, thereby decreasing energy loss and heat generation during the signal transmission process. Such a design is particularly applicable to high-speed data transmission applications, where signal integrity and transmission efficiency are extremely important. In addition, the edges of the thin-profile structure are finely polished to ensure a smooth contact surface, reduce the possibility of wear and corrosion, and thereby extend the service life of the connector.

[0052] In practical applications, the cooperation between the upper contact terminal group 2 and the lower contact terminal group 3 provides a stable electrical connection, meeting the stringent requirements for signal quality and transmission speed of high-speed data transmission equipment. Such a design not only conforms to specific industry standards but also possesses excellent versatility and scalability, allowing for customization and optimization to meet different application needs. This design enables manufacturers to provide industry-standard-compliant and competitive connector products that meet market needs for high-performance connectivity solutions.

[0053] In one possible implementation method, the thickness of the above-mentioned thin structure is 0.12 mm or less.

[0054] In one specific example, a thinned structure has a strictly controlled design thickness, with a maximum thickness of 0.12 mm or less. Such minute thickness specifications ensure that the thinned structure meets specific functional needs and usage requirements, as well as ensuring reliability and stability during its application. Limiting the thickness to such a strict range effectively improves the overall performance of the structure.

[0055] Furthermore, these thickness limitations also take into account the practical operational adaptability and portability of the thinned structures. Their ultra-thin design allows for greater space savings and easier integration into various compact equipment without affecting other aspects of the equipment's performance. At the same time, a thickness of 0.12 mm implies extremely high precision and process control during the manufacturing process, ensuring that each thinned structure meets the design criteria and thereby guaranteeing quality consistency in the final product.

[0056] In one possible implementation, the connector according to the embodiment of this application further includes an upper molded part 5 for covering the tail portion of the upper contact terminal group 2 and a lower molded part 6 for covering the tail portion of the lower contact terminal group 3.

[0057] In one specific example, the connector structure according to the embodiment of this application further includes two important molded assemblies: an upper molded part 5 and a lower molded part 6. The main function of the upper molded part 5 is to completely cover and secure the end portion of the upper contact terminal group 2, while the corresponding lower molded part 6 is used to tightly cover the tail region of the lower contact terminal group 3. These two molded parts are tightly coupled to the contact terminal group by a precise injection molding process, which not only effectively prevents displacement or deformation of the terminals during the connection process but also enhances the mechanical strength of the entire structure and ensures the stability of signal transmission. Such a dual-molded part design balances product reliability and durability while considering ease of assembly.

[0058] Furthermore, the design of the upper molded part 5 and the lower molded part 6 also takes into account the needs of heat dissipation and insulation. The upper molded part 5 is usually made of a material with excellent thermal conductivity to efficiently conduct heat from the upper contact terminal group 2 to the outside when the connector is in operation, thereby avoiding performance degradation or damage due to overheating. At the same time, the lower molded part 6 is made of a material with good insulation properties to ensure that short circuits or electric shock phenomena do not occur at the tail of the lower contact terminal group 3 during the electrical connection process, thereby ensuring the safety of the user.

[0059] The connector according to the embodiment of this application has the following beneficial effects. 1. Precisely adapted to high-speed signal transmission, reducing signal transmission obstruction and interference. The multiple openings in the separator are precisely positioned to correspond to the docking locations of the high-speed signal terminals in the upper and lower contact terminal groups. This design provides a reasonable space for docking the high-speed signal terminals, preventing the separator from obstructing or hindering the high-speed signal transmission path and ensuring smooth high-speed signal transmission. At the same time, the presence of the openings reduces unnecessary contact between the separator and the high-speed signal terminals to some extent, reducing the risk of signal interference due to contact and contributing to the maintenance of stable high-speed signal transmission. 2. Improve connection guidance and contact stability. The multiple contact protrusions at the front end of the separator are divided into a first group of contact protrusions that face the first group of contact terminals and a second group of contact protrusions that face the second group of contact terminals. These contact protrusions provide good guidance during the connector docking process, guiding the upper and lower contact terminal groups to dock accurately with the corresponding members, thereby improving docking efficiency. In addition, the contact of the contact protrusions with the upper and lower contact terminal groups increases the number of contact points between the separator and the terminal groups, improving connection stability between the separator 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. Improve grounding reliability and enhance shielding effect. The first protrusion on the side of the separator facing the first group of contact terminals and the second protrusion on the side facing the second group of contact terminals can reliably contact the corresponding terminal groups. Such a protrusion design ensures that a stable electrical connection is established between the separator and the upper and lower groups of contact terminals. In particular, in terms of grounding, it can effectively conduct any electromagnetic interference to the outside through the protrusion, increasing the shielding capability of the separator against electromagnetic signals, reducing signal crosstalk between the upper and lower groups of contact terminals, and further ensuring the transmission quality of high-definition multimedia signals.
