Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to a high-speed grounding shielded group connector with anti-disconnection feature. Background Technology

[0002] The Type-C connector (USB Type-C) is a physical interface standard for Universal Serial Bus (USB). It features reversible pluggability, high-speed data transmission, high-power charging, multi-functional integration, and compact durability. It has been widely used in consumer electronics, industrial automation, automotive electronics, and medical devices.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent with announcement number CN219610803U and announcement date of August 29, 2023) provides a Type-C connector. The Type-C connector includes a female terminal, which includes at least a first GND terminal, a second GND terminal, a first VBUS terminal, a second VBUS terminal, a CC1 terminal, and a CC2 terminal. The first GND terminal and the second GND terminal are vertically aligned and integrally formed. The first VBUS terminal and the second VBUS terminal are vertically aligned and integrally formed. The Type-C connector can be safely and efficiently charged with high current, and its manufacturing process is simpler and the cost is lower.

[0004] There is also a prior art (Chinese patent with announcement number CN207925742U and announcement date of 2018-09-28) of a vehicle-mounted Type-C connector structure, which includes an outer shielding shell, an inner iron shell, and a secondary molded plastic. The inner iron shell is fitted onto the secondary molded plastic and then fitted onto the outer shielding shell. The outer shielding shell is an integral stamping process shielding shell, reducing the traditional three iron shells to two iron shells, improving the product yield and reducing the product cost.

[0005] While existing technologies can improve product yield and reduce product costs, their connectors are susceptible to external environmental influences during use, making it difficult to achieve stable input and output. Furthermore, most existing connectors use interference fits for their internal shielding components, which can easily create gaps between the shielding components, leading to short circuits.

[0006] Therefore, we propose a high-speed grounding shielded group connector with anti-disconnection capability to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a high-speed grounding shielded group connector with anti-disconnection capability, in order to solve the problems mentioned in the background art, such as the inability of current connectors on the market to form stable input and output due to the influence of the external environment, and the fact that most of the internal shielding components of existing connectors are assembled by interference fit, which can easily create gaps between the shielding components and cause short circuits.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-speed grounding shielded group connector with anti-disconnection capability, comprising a housing, a tailstock disposed on the rear side of the housing, an inner housing disposed inside the tailstock, and a connecting housing disposed at the center of the inner housing, while high-speed components are arranged at equal intervals on the connecting housing, a shielding mechanism disposed on the connecting housing and disposed on the side of the high-speed components, and an abutment mechanism disposed on the connecting housing, the abutment mechanism further limiting the shielding mechanism by the position movement of a sliding rod.

[0009] Preferably, the shielding mechanism includes an inner shielding layer located at the center of the connecting housing, and an outer shielding layer is also disposed through the inner shielding layer, with the outer shielding layer disposed on the side of the inner shielding layer.

[0010] Preferably, the outer shielding layer is provided in two sets above and below the inner shielding layer, the inner shielding layer is made of stainless steel, and the outer shielding layer is made of high-conductivity copper, and the outer shielding layer is provided with auxiliary pressure material that arches outward on the side.

[0011] Preferably, the outer shielding layer and the two sets of inner shielding layers are welded together through a weld point, and the weld points are symmetrically distributed about the center point of the connecting shell. The weld points further improve the firmness between the outer shielding layer and the two sets of inner shielding layers, ensuring the continuity and stability of the shielding.

[0012] Preferably, the abutment mechanism includes a sliding rod, which is slidably connected to the connecting housing and is symmetrically distributed about the center point of the connecting housing. The sliding rod is located outside the outer shielding layer.

[0013] Preferably, a pull plate is fixedly connected to the outer end of the sliding rod, and the pull plate is located on the outside of the connecting housing, and a friction block is fixedly connected to the inner side of the pull plate.

[0014] Preferably, the outer side of the connecting housing is provided with a mating groove corresponding to the position of the friction block, and the mating groove is connected to the outer shielding layer mounting groove. When the pull plate moves to one side of the connecting housing, the friction block mates with the inside of the mating groove, and the side of the friction block abuts against the side of the outer shielding layer. The friction block can increase the friction with the outer shielding layer, thereby playing a preliminary limiting role for the outer shielding layer.

[0015] Preferably, the inner end of the sliding rod is rotatably connected to an abutment rod, and a torsion spring is fixedly connected between the side of the abutment rod and the inner wall of the sliding rod. The abutment rod and the sliding rod form a rotating structure through the torsion spring, and the upper and lower sets of abutment rods rotate in opposite directions.

[0016] Preferably, the inner shielding layer has abutment grooves on both the upper and lower sides. When the abutment rod is in an unrestricted state, the lower end of the abutment rod is located inside the abutment groove. The abutment groove is located on the front side of the auxiliary pressure material that is arched outward on the outer shielding layer. When the sliding rod is in the initial state, the abutment rod is located inside the connecting housing, and the abutment rod and the sliding rod are in a horizontal position.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The shielding component consists of an inner shielding layer and an outer shielding layer. The shielding component is tightly set on the outer periphery of the high-speed component, which can effectively block the leakage of internal high-speed signals and prevent external electromagnetic interference from entering the high-speed component. The outer shielding layer is set on the outside of the inner shielding layer, which further enhances the shielding effect and ensures that the high-speed component can work stably in complex electromagnetic environments. Moreover, the inner shielding layer is made of stainless steel, which has good corrosion resistance and mechanical strength and can protect the internal structure from the influence of the external environment. The outer shielding layer is made of high-conductivity copper, whose excellent conductivity can conduct electromagnetic interference more efficiently and introduce it to the grounding terminal, thereby achieving effective shielding of the high-speed component.

[0019] (2) The inner shielding layer and the outer shielding layer are firmly connected by solder joints, which avoids loosening and separation between the inner shielding layer and the outer shielding layer, further improving the reliability of shielding. It can effectively prevent the inner shielding layer from separating from the outer shielding layer due to vibration or external force during high-speed operation, thus ensuring the shielding effect of the connector. Since the solder joints are symmetrically distributed about the center point of the connecting shell, the entire shielding mechanism can distribute stress more evenly when under force, further improving the stability and reliability of the connector.

[0020] (3) After the equipment is assembled, push the pull plate to move to the side of the connecting housing. The pull plate drives the sliding rod to move synchronously along the inside of the connecting housing. Since the sliding rod is slidably connected to the connecting housing, as the sliding rod moves, the friction block at its outer end will dock with the docking groove opened on the end side of the connecting housing and abut against the side of the outer shielding layer. The friction block can increase the friction with the outer shielding layer and play a preliminary limiting role for the outer shielding layer.

[0021] (4) As the sliding rod moves, the abutment rod will rotate under the elastic force of the torsion spring. The lower end of the abutment rod will be placed in the corresponding abutment grooves opened on the upper and lower sides of the inner shielding layer. Since the abutment groove is located in front of the auxiliary pressure material arched outward on the outer shielding layer, the abutment rod will further limit the shielding mechanism after entering the abutment groove, preventing the shielding mechanism from separating. This ensures the stability and reliability of the entire anti-separation high-speed grounding shielding group connector during high-speed operation, ensures that the high-speed components can work normally in a good electromagnetic shielding environment, reduces the impact of external electromagnetic interference on high-speed signal transmission, and improves the quality and efficiency of signal transmission.

[0022] (5) When the sliding rod moves, it drives the abutment rod to rotate, so that its lower end is accurately embedded in the abutment groove, which further limits the outer shielding layer. The setting of the torsion spring allows the abutment rod to be held in a specific position when it is not subjected to external force, ensuring the stability and reliability of the mechanism. At the same time, the two sets of abutment rods are set to abut in the same direction, which can clamp the inner shielding layer, thereby further ensuring the stability of the inner shielding layer, improving the stability and reliability of signal transmission, and making the connector easy to install and maintain, reducing the cost of use and maintenance difficulty.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: In practical applications, high-speed component 7 faces the dual challenges of internal high-speed signal leakage and external electromagnetic interference intrusion. Internal high-speed signal leakage may interfere with surrounding electronic devices, affecting the overall stability of the system; while external electromagnetic interference may cause data errors, performance degradation, or even malfunctions in high-speed component 7. To solve this problem, such as... Figures 1-4 The present invention provides the following technical solution: a high-speed grounding shielded group connector with anti-disconnection capability, which is disclosed.

[0037] A tailstock 2 is provided on the rear side of the outer shell 1, and an inner shell 3 is provided inside the tailstock 2. A connecting shell 8 is provided at the center of the inner shell 3. High-speed components 7 are arranged at equal intervals on the connecting shell 8. A shielding mechanism is provided on the connecting shell 8 and is located on the side of the high-speed components 7. The shielding mechanism includes an inner shielding layer 4, which is located at the center of the connecting shell 8. An outer shielding layer 5 is also provided through the inner shielding layer 4 and is located on the side of the inner shielding layer 4. Two sets of outer shielding layers 5 are arranged above and below the inner shielding layer 4. The inner shielding layer 4 is made of stainless steel, and the outer shielding layer 5 is made of high-conductivity copper. An auxiliary pressure material arching outward is provided on the side of the outer shielding layer 5. A through-welded point 6 is provided between the outer shielding layer 5 and the two sets of inner shielding layers 4. The weld points 6 are symmetrically distributed about the center point of the connecting shell 8. The weld points 6 further improve the firmness between the outer shielding layer 5 and the two sets of inner shielding layers 4, ensuring the continuity and stability of the shielding.

[0038] The outer shielding layer 5 is located outside the inner shielding layer 4. This layered design further enhances the shielding effect. The inner shielding layer 4 is made of stainless steel, which has excellent corrosion resistance and mechanical strength, maintaining stable performance under various harsh environmental conditions and effectively protecting the internal structure from external physical and chemical factors. The outer shielding layer 5 is made of high-conductivity copper, which has excellent conductivity and can conduct electromagnetic interference more efficiently. When external electromagnetic interference comes into contact with the outer shielding layer 5, the high-conductivity copper can quickly introduce the interference current into the grounding terminal, thereby reducing the impact of interference on the high-speed component 7 and achieving effective shielding of the high-speed component 7. The inner shielding layer 4 and the outer shielding layer 5 are firmly connected by solder joints 6, effectively preventing the inner shielding from being damaged. The loosening and separation that may occur between layer 4 and outer shielding layer 5 can occur in high-speed operating scenarios. Connectors are often affected by vibration and external forces, which can cause relative displacement between inner shielding layer 4 and outer shielding layer 5, thereby compromising the integrity of the shield and reducing the shielding effect. The firm connection of solder points 6 ensures that inner shielding layer 4 and outer shielding layer 5 always maintain close contact, forming a continuous and stable shield, effectively preventing separation caused by vibration or external forces, thus ensuring the shielding effect of the connector. The symmetrically distributed solder points 6 can evenly distribute stress throughout the shielding mechanism, avoiding damage to solder points 6 or deformation of the shielding layer caused by local stress concentration, further improving the stability and reliability of the connector.

[0039] Example 2: To further improve the stability between the inner shielding layer 4 and the outer shielding layer 5, an abutment mechanism is provided, such as... Figure 7 , Figure 9 and Figure 11 The present invention provides the following technical solution: a high-speed grounding shielded group connector with anti-disconnection feature, wherein a contact mechanism is provided on the connecting housing 8, and the contact mechanism further limits the shielding mechanism by moving the position of the sliding rod 13. The contact mechanism includes a sliding rod 13, which is slidably connected to the connecting housing 8, and the sliding rods 13 are symmetrically distributed about the center point of the connecting housing 8. The sliding rods 13 are located outside the outer shielding layer 5, and a pull plate 9 is fixedly connected to the outer end of the sliding rod 13. Plate 9 is located on the outside of the connecting housing 8, and friction block 11 is fixedly connected to the inside of the pull plate 9. A docking groove 10 corresponding to the position of friction block 11 is opened on the outside of the connecting housing 8, and the docking groove 10 is connected to the mounting groove of the outer shielding layer 5. When the pull plate 9 moves to one side of the connecting housing 8, the friction block 11 docks into the inside of the docking groove 10, and the side of the friction block 11 abuts against the side of the outer shielding layer 5. The friction block 11 can increase the friction with the outer shielding layer 5, thereby playing a preliminary limiting role for the outer shielding layer 5.

[0040] During equipment assembly, an external force is applied to the pull plate 9, causing it to move towards the side of the connecting housing 8. As the pull plate 9 moves, it simultaneously drives the sliding rod 13 to move linearly along the inside of the connecting housing 8. The sliding rod 13 is slidably connected to the connecting housing 8, ensuring that the sliding rod 13 can slide smoothly and steadily inside the connecting housing 8. As the sliding rod 13 continues to move, the friction block 11 installed at its outer end will gradually approach and eventually dock with the pre-drilled docking groove 10 on the end side of the connecting housing 8, achieving precise docking. After the friction block 11 is fully inserted into the docking groove 10, it will make tight contact with the side of the outer shielding layer 5, which can increase the friction between the outer shielding layer 5 and the outer shielding layer 5, thus playing a preliminary limiting role for the outer shielding layer 5 and preventing unnecessary displacement of the outer shielding layer 5 during equipment operation, thereby ensuring the stability and reliability of the overall structure of the equipment.

[0041] Example 3: To further ensure that the inner shielding layer 4 and the outer shielding layer 5 do not separate, such as... Figures 5-10 The present invention provides the following technical solution: a high-speed grounding shielded group connector with anti-disconnection, wherein the inner end of the sliding rod 13 is rotatably connected to the abutment rod 12, and the side of the abutment rod 12 is fixedly connected to the inner wall of the sliding rod 13 with a torsion spring 14, and the abutment rod 12 and the sliding rod 13 form a rotating structure through the torsion spring 14. At the same time, the upper and lower abutment rods 12 rotate in opposite directions. The upper and lower sides of the inner shielding layer 4 are provided with abutment grooves 15. When the abutment rod 12 is in an unrestricted state, the lower end of the abutment rod 12 is located inside the abutment groove 15. The abutment groove 15 is located in front of the auxiliary pressure material arched outward on the outer shielding layer 5. When the sliding rod 13 is in the initial state, the abutment rod 12 is located inside the connecting housing 8, and the abutment rod 12 and the sliding rod 13 are in a horizontal position.

[0042] As the sliding rod 13 moves, the abutment rod 12, driven by the sliding rod 13, gradually moves from its initial position to the outside of the connecting housing 8. The blocking and limiting effect of the connecting housing 8 on the abutment rod 12 gradually disappears. The abutment rod 12 is connected to the torsion spring 14. When the connecting housing 8 no longer limits its movement, the torsion spring 14, with its elastic force, begins to drive the abutment rod 12 to rotate. When the sliding rod 13 moves to a specific position, the lower end of the abutment rod 12 is precisely placed in the corresponding abutment grooves 15 on the upper and lower sides of the inner shielding layer 4. This allows the abutment rod 12 to form a tight fit with the inner shielding layer 4 and the outer shielding layer 5 after entering the abutment groove 15, effectively preventing the shielding mechanism from separating during high-speed operation. This provides a good electromagnetic shielding environment for the high-speed component 7 and reduces external interference. To mitigate the impact of electromagnetic interference on high-speed signal transmission and improve signal transmission quality and efficiency, thus meeting the needs of high-speed communication and data processing, the torsion spring 14 provides a stable restoring force to the abutment rod 12 through its elastic properties. When the abutment rod 12 is not subjected to external force, the torsion spring 14 can keep it in a pre-set specific position, thereby ensuring that the entire mechanism maintains a stable structural form under both static and dynamic conditions. The two sets of abutment rods 12 are arranged in the same direction, so that the two sets of abutment rods 12 can simultaneously apply force to the inner shielding layer 4, forming a symmetrical and uniform clamping effect. This makes the force on the inner shielding layer 4 more balanced in all directions, effectively resisting external vibration, impact and other interference factors, and further improving the stability of the inner shielding layer 4.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
