Description

Technical Field

[0001] This utility model relates to the field of terminal technology, specifically to a high-speed transmission plug with an anti-interference grounding pin short-circuited. Background Technology

[0002] With the development of information technology, application scenarios such as high-definition video streaming and fast backup of large files have placed higher demands on data transmission rates. The previous generation of USB 3.0 interface standard (transmission rate of 5Gbps) has gradually become unable to meet the needs of these high-speed data interactions. Therefore, the USB 3.1 standard was born, which significantly improves the data transmission rate to 10Gbps, while retaining the good feature of backward compatibility with USB 3.0.

[0003] However, the doubling of transmission rates poses a severe challenge to the high-frequency signal integrity of connectors. At high speeds, signals are susceptible to impedance discontinuities, crosstalk, and signal attenuation, leading to waveform distortion and increased bit error rate. Some existing high-speed connectors use simple point contacts or sheet-like structures to short-circuit the grounding pins next to the signal terminals. However, in high-frequency environments of 10Gbps and above, the stability and reliability of this connection are insufficient, making it difficult to guarantee the continuous consistency of characteristic impedance, thus becoming a bottleneck restricting signal transmission quality.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0048] The following describes in detail, with reference to the accompanying drawings, a high-speed transmission plug with an anti-interference grounding pin shorted according to an embodiment of the present invention.

[0049] Please see Figures 1-7In this embodiment, it includes: a first module component 1, a second module component 2, and a housing 3; the first module component 1 is embedded in the second module component 2, and the housing 3 is sleeved on the first module component 1 and the second module component 2; the ends of the first module component 1 and the ends of the second module component 2 together enclose a fixing groove, and a metal sheet 4 is provided in the fixing groove. One side of the metal sheet 4 is connected to the first module component 1, and the other side of the metal sheet 4 is connected to the second module component 2.

[0050] Through an innovatively designed metal sheet 4 structure, a stable and reliable low-impedance short circuit is achieved between the grounding pins on both sides of the high-speed signal group, thereby optimizing the high-frequency signal path. When the first module component 1 and the second module component 2 are interlocked, the first mounting groove 104 and the second mounting groove 204 on their tops together form a fixing groove. The specially designed metal sheet 4 is securely housed in this fixing groove, and the metal sheet 4 connects the first module component and the second module component. The metal sheet 4 acts like a "bridge", connecting the grounding terminals next to the high-speed signal groups of the upper and lower modules together with low resistance and high efficiency, forming a common ground shielding layer.

[0051] In this embodiment, the first module component 1 includes: a first MD component 101, which can be replaced according to the shape of the interface (e.g., Figure 2 (As shown); First storage slot 102, the first storage slot 102 is disposed on the first MD part 101 and is arranged along the length direction of the first MD part 101; First terminal assembly 103, the first terminal assembly 103 is embedded in the first storage slot 102; First mounting slot 104, the first mounting slot 104 is disposed on the top of the inner side of the first MD part 101; Two first connecting slots 105, the two first connecting slots 105 are disposed in the first mounting slot 104 and are respectively arranged opposite to each other, and the two first connecting slots 105 are connected to the first storage slot 102;

[0052] By setting an independent first MD component 101 as the structural basis, the modularity of the first terminal assembly 103 and its related structures is realized. This modular design allows the assembly and testing of the first terminal assembly 103 to be completed in an independent sub-module, simplifying the overall assembly process and improving production efficiency. The first placement slot 102 is preset on the first MD component 101 along the length direction, providing the first terminal assembly 103 with a precise installation position and reliable accommodating space, ensuring the relative position accuracy of multiple terminals, and structurally guaranteeing the stability of characteristic impedance.

[0053] The first mounting groove 104, located on the top inner side of the first MD component 101, serves as one of the "bases" for the metal sheet 4. This dedicated groove design ensures that the metal sheet 4 can be precisely positioned and fixed, preventing displacement during assembly of the housing 3 or during use, thereby guaranteeing the long-term reliability of the short-circuit effect.

[0054] The design of the two first connecting slots 105 is a key innovation. They act as "bridges," precisely connecting the metal plate 4 in the first mounting slot 104 to the grounding terminal in the first storage slot 102. This "point-to-point" connection method achieves the shortest and most direct electrical path between the shorted end of the metal plate 4 and the grounding terminal, effectively reducing connection impedance and providing an optimized grounding loop for high-frequency signals. The combined effect of the above structures directly contributes to improving signal integrity. The first storage slot 102 ensures the precise positioning of the signal terminals, reducing impedance abrupt changes; the first mounting slot 104 and the first connecting slot 105 ensure the stability and efficiency of the grounding short circuit. Together, they effectively reduce crosstalk and signal attenuation during high-speed signal transmission, forming an indispensable structural foundation for achieving high-performance USB 3.1 (10Gbps) transmission.

[0055] The refined structure of the first module component 1 not only brings convenience and reliability in production, but more importantly, it provides a key physical carrier for achieving stable, low-impedance grounding short circuits, directly constituting the core support for the anti-interference and high-speed transmission capabilities of this utility model.

[0056] In this embodiment, the second module component 2 includes: a second MD component 201, which can be replaced according to the shape of the interface (e.g., Figure 2 (As shown); Second storage slot 202, the second storage slot 202 is disposed on the second MD part 201 and is arranged along the length direction of the second MD part 201; Second terminal assembly 203, the second terminal assembly 203 is embedded in the second storage slot 202; Second mounting slot 204, the second mounting slot 204 is disposed on the top of the inner side of the second MD part 201, the first mounting slot 104 and the second mounting slot 204 together form a fixing slot; Two second connecting slots 205, the two second connecting slots 205 are disposed in the second mounting slot 204 and are respectively arranged opposite to each other, and the two second connecting slots 205 are connected to the second storage slot 202;

[0057] The second module component 2, as a symmetrical coupling part with the first module component 1, plays a core role in working together with the first module component 1 to form the fixing groove. This "top and bottom cover" design ensures that the metal sheet 4 can be evenly and firmly fixed in the preset position, avoiding the loosening problem that may be caused by unilateral fixing, and providing a structurally symmetrical and mechanically stable environment for grounding short circuit. The precise fit between the second mounting groove 204 and the first mounting groove 104 is the basis for forming this ideal fixing groove, reflecting the synergistic advantages of modular design.

[0058] Similar to the first module component 1, the second connecting slot 205 on the second module component 2 plays a crucial role. It ensures that the shorting end on the other side of the metal plate 4 can be connected to the grounding terminal of the second terminal component 203 with the same precision and directness. This symmetrical connecting structure allows the metal plate 4 to efficiently short-circuit the grounding terminals located in the two independent modules together, forming a complete and balanced common ground system. This symmetry helps to maintain the symmetry and stability of the signal return path, which is crucial for canceling common-mode noise in differential signal transmission and further suppressing electromagnetic interference.

[0059] The defined second module component 2 structure is not a simple repetition of the first module component 1, but an indispensable other half to achieve complete, symmetrical, and stable grounding short-circuit function; together with the first module component 1, it forms a closed, high-performance signal transmission and shielding cavity, which is a structural guarantee to ensure that the present invention can maintain excellent signal integrity at a high speed of 10Gbps.

[0060] In this embodiment, multiple first storage slots 102 and second storage slots 202 are provided and are equally spaced on the first MD component 101 and the second MD component 201; the first terminal assembly 103 and the second terminal assembly 203 are each composed of multiple connecting pieces.

[0061] By setting multiple equally spaced storage slots on the first MD component 101 and the second MD component 201, the plug can accommodate multiple sets of signal terminal pairs; this high-density layout is the basis for supporting the multi-channel data parallel transmission capability required by high-speed standards such as USB 3.1, and directly meets the high bandwidth requirements of applications such as high-definition video and large file copying.

[0062] The equidistant spacing is crucial, ensuring a high degree of consistency between the geometry and electrical environment of adjacent signal channels. This consistency is essential for maintaining the characteristic impedance of high-speed differential signal lines, effectively reducing signal reflections caused by impedance mismatch, thereby lowering signal distortion and bit error rate. Each terminal assembly consists of multiple independent connecting tabs (terminal contacts), allowing for the use of specially optimized contacts for each signal channel or ground channel. This design facilitates independent shape and size optimization for terminals with different functions (such as high-speed data terminals and ground terminals) to precisely control their impedance parameters, further ensuring continuous and stable impedance throughout the transmission path.

[0063] The regular layout of multiple storage slots with equal spacing allows the first MD part 101 and the second MD part 201 to be processed using a modular and standardized design (such as one-time injection molding using precision molds), which greatly improves the manufacturing precision and production efficiency of the parts and ensures the consistency between product batches; the complex terminal system is decomposed into multiple independent connecting pieces for assembly, which reduces the complexity of individual parts and the assembly difficulty, and improves the yield rate of production.

[0064] In this embodiment, one side of the metal sheet 4 is provided with two first shorting ends 401, which are arranged in a figure-eight pattern. The two first shorting ends 401 are respectively disposed in two first connecting grooves 105 and connected to the first terminal assembly 103. The other side of the metal sheet 4 is provided with two second shorting ends 402, which are arranged in a figure-eight pattern. The two second shorting ends 402 are respectively disposed in two second connecting grooves 205 and connected to the second terminal assembly 203.

[0065] The “eight” figure-eight structure means that the short-circuit end has a certain opening angle in its natural state. When the metal sheet 4 is pressed into the fixing groove and the short-circuit end is inserted into the connecting groove and contacts the grounding terminal, a continuous elastic restoring force will be generated. This elastic contact ensures that the pressure between the contact points is stable, effectively overcomes the problem of poor contact caused by the dimensional tolerance of the parts or slight wear, and ensures the long-term reliability of the grounding short-circuit effect and low contact resistance.

[0066] The metal sheet 4 adopts a symmetrical figure-eight distribution design on both sides, providing a completely symmetrical low-impedance return path for the grounding terminals in the first module component 1 and the second module component 2. This symmetry is crucial for high-speed differential signal transmission. It can ensure that the grounding reference potential on both sides of the signal line pair is consistent and the return path is balanced, thereby significantly reducing common-mode noise, effectively suppressing crosstalk between signals, and providing a "clean" transmission environment for 10Gbps high-speed signals.

[0067] The figure-eight shaped opening design plays a guiding and centering role during assembly; when the upper and lower modules are closed, the opening angle can tolerate slight alignment deviations, guiding the short-circuit terminals to slide smoothly into the corresponding connecting slots, avoiding terminal damage or metal sheet deformation caused by forced assembly, reducing assembly difficulty, and improving production efficiency and product yield.

[0068] This bidirectional, angled elastic contact structure creates a tight three-dimensional mechanical interlock between the metal sheet 4 and the upper and lower module components. It not only provides electrical connection but also physically enhances the tightness of the module component connection, improves the overall resistance of the plug to vibration and mechanical shock, and further ensures the stability of electrical performance under harsh operating environments.

[0069] In this embodiment, two fitting blocks 106 are respectively provided on both sides of the middle part of the first MD component 101, and the ends of the two fitting blocks 106 are L-shaped; two fitting grooves 206 are respectively provided on both sides of the middle part of the second MD component 201, and the two fitting blocks 106 are respectively embedded in the two fitting grooves 206. The two fitting grooves 206 are respectively provided with bosses, which are respectively engaged with the ends of the two fitting grooves 206.

[0070] By cooperating with the fitting block 106 and the fitting groove 206, the first MD component 101 and the second MD component 201 are first accurately positioned in the horizontal (left-right direction); this ensures that the key structures such as the upper and lower side storage grooves, mounting grooves, and connecting grooves can be perfectly aligned, thereby ensuring that the first terminal assembly 103, the second terminal assembly 203 and the short-circuit end of the metal sheet 4 can make accurate contact, which is a prerequisite for achieving stable electrical performance;

[0071] The L-shaped end and the boss work together to form a highly efficient mechanical lock. When the two module components are closed in the vertical direction, the L-shaped end hooks onto the boss, generating strong mechanical resistance. This effectively prevents the modules from accidentally separating or shifting laterally due to external forces during use. It significantly enhances the rigidity and stability of the overall plug structure, enabling it to withstand the stress and possible torsional force generated during insertion and removal, protecting the delicate internal terminal contacts from damage, and greatly improving the product's mechanical life and reliability.

[0072] This interlocking structure serves as a guide and final positioning mechanism during assembly. When the interlocking block 106 slides into the interlocking groove 206 to its final position, the engagement between the L-shaped end and the boss provides a clear "click" or sense of completion, allowing operators to intuitively confirm whether the assembly is complete and in place. This simplifies the quality control process and improves production efficiency.

[0073] In this embodiment, the inner side of the first MD component 101 is provided with a plurality of positioning blocks 107, which are arranged at equal intervals; the inner side of the second MD component 201 is provided with a plurality of positioning grooves 207, which are arranged at equal intervals, and the plurality of positioning blocks 107 correspond to the plurality of positioning grooves 207 respectively.

[0074] Multiple equally spaced positioning blocks 107 and positioning slots 207 provide multiple evenly distributed positioning points along the length of the module component. This "multi-point positioning" mechanism effectively prevents warping, tilting, or longitudinal misalignment of the two modules when they are joined, ensuring that they maintain precise alignment in multiple dimensions. This precise alignment is fundamental, directly guaranteeing that key structures such as the first storage slot 102 and the second storage slot 202, and the first connecting slot 105 and the second connecting slot 205 belonging to the upper and lower modules can perfectly match. Only in this way can the short-circuit end of the metal sheet 4 make reliable contact with the grounding terminals on both the upper and lower sides without deviation, which is a prerequisite for achieving a stable, low-impedance grounding short circuit.

[0075] Multiple positioning blocks 107 distributed throughout the inner side of the module and positioning grooves 207 engage with each other after fitting, forming an effect similar to a "mortise and tenon structure". This greatly enhances the bending and torsional resistance of the entire internal structure of the plug; this enhanced rigidity ensures that the relative position of the internal terminals and the metal plate 4 will not change slightly under insertion and removal operations or external stress, thereby maintaining the stability of characteristic impedance and the reliability of contact over a long period of time, and improving the durability of the product;

[0076] This design provides clear guidance and limits for the assembly process, enabling operators to easily and quickly align and press the two modules together accurately, reducing assembly difficulty and dependence on operational skills; the regular layout of "equal spacing" is conducive to the processing and manufacturing of precision molds, ensuring the high precision and high consistency of the parts themselves, thereby improving production yield and ensuring the high stability of product performance in mass production.
