Description

Technical Field

[0001] The utility model relates to the technical field of terminals, in particular to a DISPLAYPOR female seat high-frequency terminal structure. Background Art

[0002] DisplayPort (DP) is a digital video interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). This certification- and royalty-free interface is primarily used to connect video sources to devices such as displays, while also supporting audio, USB, and other data. It was designed to replace traditional VGA, DVI, and FPD-Link (LVDS) interfaces. It is backwards compatible with legacy interfaces such as HDMI and DVI via active or passive adapters.

[0003] High-frequency terminals are connectors or interfaces used to transmit high-frequency signals. They are typically designed to handle high-speed data transmission or high-frequency electrical signals. These terminals are crucial in electronic devices, particularly in communications systems that require high bandwidth and low loss. The design of high-frequency terminals must consider signal integrity to minimize signal attenuation and interference. Common high-frequency terminal types include SMA, SMB, MCX, and MMCX, which are widely used in wireless communications, radio frequency identification (RFID), satellite communications, test and measurement equipment, and other fields.

[0004] The width of the front end contact part of the signal transmission PIN and the grounding PIN of the existing high-frequency terminal is consistent, which leads to the consistency of resistance and force area in the high-frequency test, resulting in poor signal transmission and easy signal interference or disconnection limit. In the circulation of high-frequency signals, the transmission pass rate is the inspection criterion, but due to the consistent shape and structure of the existing high-frequency terminals, the product performance cannot meet the high-performance requirements, and the structure needs to be further processed and improved, which increases the process and reduces work efficiency. For this reason, the inventors proposed a DISPLAYPOR female high-frequency terminal structure to solve the above-mentioned technical problem of increasing the high-frequency signal circulation pass rate through structural improvement. Utility Model Content

[0005] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0006] A DISPLAYPOR female high-frequency terminal structure includes a terminal body, a terminal head strip and a terminal tail strip. The terminal body, the terminal head strip and the terminal tail strip are an integral stamped structure. The terminal body includes a first connecting part, a second connecting part, a third connecting part and a fourth connecting part. A bending part is connected between the first connecting part, the second connecting part, the third connecting part and the fourth connecting part. One end of the first connecting part is connected to the surface of the terminal tail strip, and one end of the fourth connecting part is connected to the surface of the terminal head strip. The terminal body includes a signal PIN terminal group and a ground PIN terminal group.

[0007] Furthermore, the diameter of the first connecting portion is smaller than the diameter of the second connecting portion. This structure is to design the widths of the contact parts of the front ends of the signal transmission PIN terminal structure and the ground PIN terminal to be different widths. The width of the ground terminal is wider than the width of the signal transmission PIN terminal, so that the ground PIN terminal is closer to the signal transmission PIN terminal, which is conducive to eliminating noise and interference signals, thereby facilitating high-frequency testing, so that high-frequency testing can be passed better, so that product performance can meet higher performance requirements and product quality is higher.

[0008] Furthermore, the diameter of the second connecting portion is consistent with the diameter of the third connecting portion. The consistent diameter setting can ensure the consistency of strength and durability of the connecting parts, avoid stress concentration caused by size differences, and reduce the probability of deformation.

[0009] Furthermore, the diameter of the fourth connecting portion is smaller than the diameter of the third connecting portion. This structure is designed to have different widths of the contact portion of the front end of the signal transmission PIN terminal structure and the ground PIN terminal. The width of the ground terminal is wider than the width of the signal transmission PIN terminal, thereby making the ground PIN terminal closer to the signal transmission PIN terminal, which is beneficial to eliminating noise and interference signals, thereby facilitating high-frequency testing, enabling high-frequency testing to pass better, thereby enabling product performance to meet higher performance requirements and higher product quality.

[0010] Furthermore, the bending portion includes a first bending portion, the first bending portion is located between the first connecting portion and the second connecting portion, the first bending portion is in an S-shaped opposing arc shape, and the curvature of the first bending portion is 45°; the use of a 45° arc shape helps to disperse stress and reduce stress concentration at the bending point, thereby improving the strength and durability of the overall structure, and the S-shaped opposing arc design can more effectively utilize materials and reduce material waste while maintaining structural stability and functionality. At the same time, the S-shaped design allows the bending portion to occupy a smaller volume in space, which helps to achieve a more compact layout in a limited space;

[0011] On the other hand, the first bend of the S-shape has the ability to improve fluid dynamics and effectively reduce reflections and interference during signal transmission. For applications involving fluid flow, the 45° arc shape can reduce fluid resistance, improve the efficiency of fluid passage, reduce impedance, and improve transmission stability.

[0012] Furthermore, the bending portion includes a second bending portion, the second bending portion is located between the second connecting portion and the third connecting portion, the second bending portion is arc-shaped, and the curvature of the second bending portion is 67°;

[0013] The use of an arc shape helps to evenly distribute stress on the material during the bending process, reducing stress concentration and thus improving the stability and durability of the structure. In addition, the specific arc of 67° is the optimal angle obtained after multiple tests and calculations. It can ensure that the bending part maintains the coordination of the overall structure while meeting specific functional requirements. In addition, the angle may take into account the physical properties of the material, such as elastic modulus and yield strength, to ensure that cracks or fractures will not occur due to excessive bending in actual use, so as to leave enough margin to support the deformation of the arc and avoid product fracture due to excessive elastic modulus and yield strength. The design takes into account the overall size and space limitations of the product to ensure the best bending effect within a limited space.

[0014] Furthermore, the bending portion includes a third bending portion, the third bending portion is located between the third connecting portion and the fourth connecting portion, the third bending portion is arc-shaped, and the curvature of the third bending portion is 80°;

[0015] The 80° arc shape ensures that the material is subjected to uniform stress distribution during the bending process, reduces stress concentration at the bend, and thus improves the bending performance and durability of the material. In addition, the 80° bending angle can achieve a larger bending radius within a limited space, which helps to maintain sufficient strength and stability in a compact structural design. At the same time, the arc-shaped bend can effectively disperse the load and reduce stress concentration at the bend, thereby enhancing the strength and stability of the entire structure.

[0016] Furthermore, the terminal tail strip is in the shape of a rectangular strip, and the terminal tail strip and the first connecting portion are an integrally stamped structure. Both ends of the terminal tail strip are provided with crescent-shaped crescent grooves, and the crescent groove structures are symmetrically located at both ends of the terminal tail strip. A through hole is provided in the middle of the terminal tail strip, and a folded angle is provided on the surface of the terminal body. The folded angle plays a role in assisting buffering and reducing reflections and interference during signal transmission, thereby improving the right-angle return method and reducing the occurrence of the phenomenon of right-angle hedge formation;

[0017] A through hole is opened in the middle of the terminal tail strip, which can be used to install or fix the terminal tail strip to ensure its correct position and stability in the electronic device. In addition, the through hole can also be used as a channel for wires to pass through and connect other circuit components, facilitating electrical connection and signal transmission. The through hole design simplifies the assembly process, improves assembly efficiency, and helps to reduce the use of materials, thereby reducing costs. The crescent groove plays a role in position limitation, preventing the through hole from acting as a force point and experiencing circular motion.

[0018] Furthermore, the signal PIN terminal group includes a first signal PIN terminal group and a second signal PIN terminal group, surfaces of the first signal PIN terminal group and the second signal PIN terminal group are provided with a contraction angle, and the first signal PIN terminal group and the second signal PIN terminal group are both in contact with the surface of the terminal head strip through the signal terminal pins;

[0019] The design of the contraction angle can effectively reduce reflections and interference during signal transmission. Since it contracts toward the inside of the signal PIN terminal group, it reduces resistance to achieve precise conduction, reduces electromagnetic interference (EMI) and radio frequency interference (RFI), and improves signal stability and transmission efficiency. At the same time, the signal terminal pin abuts against the surface of the terminal head strip, which can ensure the continuity and reliability of signal transmission, reduce the possibility of poor contact, and thus improve the overall electrical performance and connection stability.

[0020] Furthermore, the ground PIN terminal group includes a first ground PIN terminal group and a second ground PIN terminal group, a blanking groove is separated between the signal PIN terminal group and the ground PIN terminal group, the first ground PIN terminal group and the second ground PIN terminal group are both in contact with the surface of the terminal head strip through the ground terminal pins, and the length of the ground terminal pins is shorter than the length of the signal terminal pins;

[0021] Setting the length of the ground terminal pin to be shorter than the length of the signal terminal pin helps reduce the inductance of the ground loop, thereby improving the signal transmission quality. The shorter ground pin can shorten the length of the current loop and reduce electromagnetic interference (EMI) and radio frequency interference (RFI), which is particularly important for high-speed signal transmission. In addition, the shorter ground pin can also reduce the ground impedance and improve the stability of the ground, which helps to ensure the integrity of the signal and the reliable operation of the equipment.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the widths of the front contact portions of the signal transmission PIN terminal structure and the ground PIN terminal are designed to be different, with the ground terminal being wider than the signal transmission PIN terminal. This allows the ground PIN terminal to be closer to the signal transmission PIN terminal, facilitating the elimination of noise and interference signals, thereby facilitating high-frequency testing and enabling high-frequency testing to pass more effectively, thereby enabling product performance to meet higher performance requirements and achieving higher product quality.

[0023] The varying widths of the wires help reduce loop inductance, thereby improving signal transmission quality. A narrower setting shortens the length of the current loop, reducing electromagnetic interference (EMI) and radio frequency interference (RFI), which is particularly important for high-speed signal transmission. Furthermore, narrower bends and connections reduce impedance and improve grounding stability, helping to ensure signal integrity and reliable equipment operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0042] For this example, please refer to Figures 1-16, which specifically implements a DISPLAYPOR female high-frequency terminal structure, including a terminal body 1, a terminal head strip 2 and a terminal tail strip 3, the terminal body 1, the terminal head strip 2 and the terminal tail strip 3 are an integral stamping structure, the terminal body 1 includes a first connecting part 4, a second connecting part 5, a third connecting part 6 and a fourth connecting part 7, and a bending part is connected between the first connecting part 4, the second connecting part 5, the third connecting part 6 and the fourth connecting part 7. One end of the first connecting part 4 is connected to the surface of the terminal tail strip 3, and one end of the fourth connecting part 7 is connected to the surface of the terminal head strip 2. The terminal body 1 includes a signal PIN terminal group 8 and a ground PIN terminal group 9.

[0043] The diameter of the first connecting portion 4 is smaller than that of the second connecting portion 5. This structure is designed to have different widths for the contact portion of the front end of the signal transmission PIN terminal structure and the ground PIN terminal. The width of the ground terminal is wider than that of the signal transmission PIN terminal, so that the ground PIN terminal is closer to the signal transmission PIN terminal, which is beneficial to eliminating noise and interference signals, thereby facilitating high-frequency testing and enabling high-frequency testing to pass better, thereby enabling product performance to meet higher performance requirements and higher product quality.

[0044] The diameter of the second connecting portion 5 is consistent with the diameter of the third connecting portion 6. The consistent diameter setting can ensure the consistency of strength and durability of the connecting parts, avoid stress concentration caused by size difference, and reduce the probability of deformation.

[0045] The diameter of the fourth connecting portion 7 is smaller than that of the third connecting portion 6. This structure is designed to have different widths for the contact portion of the front end of the signal transmission PIN terminal structure and the ground PIN terminal. The width of the ground terminal is wider than that of the signal transmission PIN terminal, so that the ground PIN terminal is closer to the signal transmission PIN terminal, which is beneficial for eliminating noise and interference signals, thereby facilitating high-frequency testing and enabling high-frequency testing to pass better, thereby enabling product performance to meet higher performance requirements and higher product quality.

[0046] The bending portion includes a first bending portion 10, which is located between the first connecting portion 4 and the second connecting portion 5. The first bending portion 10 is S-shaped and faces an arc, and the curvature of the first bending portion 10 is 45°.

[0047] The 45° arc shape helps disperse stress and reduce stress concentration at the bend, thereby improving the strength and durability of the overall structure. The S-shaped opposing arc design can more effectively utilize materials and reduce material waste while maintaining structural stability and functionality. At the same time, the S-shaped design makes the bend occupy a smaller volume in the space, which helps to achieve a more compact layout in a limited space.

[0048] On the other hand, the S-shaped first bend 10 has improved fluid dynamics characteristics and can effectively reduce reflections and interference during signal transmission. For applications involving fluid flow, the 45° arc shape can reduce fluid resistance, improve the efficiency of fluid passage, reduce impedance, and improve transmission stability.

[0049] The bending portion includes a second bending portion 11, which is located between the second connecting portion 5 and the third connecting portion 6. The second bending portion 11 is arc-shaped, and the curvature of the second bending portion 11 is 67°.

[0050] The use of an arc shape helps to evenly distribute stress on the material during the bending process, reducing stress concentration and thus improving the stability and durability of the structure. In addition, the specific arc of 67° is the optimal angle obtained after multiple tests and calculations. It can ensure that the bending part maintains the coordination of the overall structure while meeting specific functional requirements. In addition, the angle may take into account the physical properties of the material, such as elastic modulus and yield strength, to ensure that cracks or fractures will not occur due to excessive bending in actual use, so as to leave enough margin to support the deformation of the arc and avoid product fracture due to excessive elastic modulus and yield strength. The design takes into account the overall size and space limitations of the product to ensure the best bending effect within a limited space.

[0051] The bending portion includes a third bending portion 12, which is located between the third connecting portion 6 and the fourth connecting portion 7. The third bending portion 12 is arc-shaped, and the curvature of the third bending portion 12 is 80°.

[0052] The 80° arc shape ensures that the material is subjected to uniform stress distribution during the bending process, reduces stress concentration at the bend, and thus improves the bending performance and durability of the material. In addition, the 80° bending angle can achieve a larger bending radius within a limited space, which helps to maintain sufficient strength and stability in a compact structural design. At the same time, the arc-shaped bend can effectively disperse the load and reduce stress concentration at the bend, thereby enhancing the strength and stability of the entire structure.

[0053] The terminal tail strip 3 is in the shape of a rectangular strip. The terminal tail strip 3 and the first connecting portion 4 are integrally stamped and formed. Both ends of the terminal tail strip 3 are provided with crescent-shaped crescent grooves 13. The crescent grooves 13 are symmetrically located at both ends of the terminal tail strip 3. A through hole 14 is provided in the middle of the terminal tail strip 3. The surface of the terminal body 1 is provided with a folded corner 23. The folded corner 23 plays a role in assisting buffering and reducing reflection and interference during signal transmission, thereby improving the right-angle return flow method and reducing the occurrence of the phenomenon of right-angle hedge formation.

[0054] A through hole 14 is provided in the middle of the terminal tail strip 3, which can be used to install or fix the terminal tail strip 3 to ensure its correct position and stability in the electronic device. In addition, the through hole 14 can also be used as a channel for the wire to pass through to connect other circuit elements, facilitating electrical connection and signal transmission. The design of the through hole 14 simplifies the assembly process, improves assembly efficiency, and helps to reduce the use of materials, thereby reducing costs. The crescent groove 13 plays a role in position limitation, preventing the through hole 14 from acting as a force point and exhibiting circular motion.

[0055] The signal PIN terminal group 8 includes a first signal PIN terminal group 15 and a second signal PIN terminal group 16. The surfaces of the first signal PIN terminal group 15 and the second signal PIN terminal group 16 are provided with a contraction angle 17. The first signal PIN terminal group 15 and the second signal PIN terminal group 16 are both in contact with the surface of the terminal head strip 2 through signal terminal pins 18.

[0056] The design of the contraction angle 17 can effectively reduce reflections and interference during signal transmission. Since it contracts toward the inside of the signal PIN terminal group 8, it reduces resistance to achieve precise conduction, reduces electromagnetic interference (EMI) and radio frequency interference (RFI), and improves signal stability and transmission efficiency. At the same time, the signal terminal pin 18 abuts against the surface of the terminal head strip 2, which can ensure the continuity and reliability of signal transmission, reduce the possibility of poor contact, and thus improve the overall electrical performance and connection stability.

[0057] The ground PIN terminal group 9 includes a first ground PIN terminal group 19 and a second ground PIN terminal group 20. A blanking groove 21 is provided between the signal PIN terminal group 8 and the ground PIN terminal group 9. The first ground PIN terminal group 19 and the second ground PIN terminal group 20 are both in contact with the surface of the terminal head strip 2 via ground terminal pins 22. The length of the ground terminal pins 22 is less than that of the signal terminal pins 18.

[0058] The setting that the length of the ground terminal pin 22 is shorter than the length of the signal terminal pin 18 helps to reduce the inductance of the ground loop, thereby improving the signal transmission quality. The shorter ground pin can shorten the length of the current loop and reduce electromagnetic interference (EMI) and radio frequency interference (RFI), which is particularly important for high-speed signal transmission. In addition, the shorter ground pin can also reduce the grounding impedance, improve the stability of the grounding, and help ensure the integrity of the signal and the reliable operation of the equipment.

[0059] The signal PIN terminal group 8 and the ground PIN terminal group 9 are both composed of a first connecting portion 4 , a second connecting portion 5 , a third connecting portion 6 , a fourth connecting portion 7 , a first bending portion 10 , a second bending portion 11 , and a third bending portion 12 connected in combination.

[0060] The key design points of the present invention are that the widths of the front contact portions of the signal transmission PIN terminal structure and the ground PIN terminal are designed to be different. The width of the ground terminal is wider than that of the signal transmission PIN terminal, thereby bringing the ground PIN terminal closer to the signal transmission PIN terminal. This helps eliminate noise and interference signals, thus facilitating high-frequency testing and enabling high-frequency testing to pass more effectively. This allows the product to meet higher performance requirements and achieve higher product quality.

[0061] The varying widths of the wires help reduce loop inductance, thereby improving signal transmission quality. A narrower setting shortens the length of the current loop, reducing electromagnetic interference (EMI) and radio frequency interference (RFI), which is particularly important for high-speed signal transmission. Furthermore, narrower bends and connections reduce impedance and improve grounding stability, helping to ensure signal integrity and reliable equipment operation.

[0062] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered as within the scope of protection of the present invention.
