[0017] Compared with the prior art, the application has the following beneficial effects: (1) The shielding assembly is composed of an inner shielding layer and an outer shielding layer, and is closely arranged on the outer periphery of the high-speed assembly, which can effectively block the leakage of internal high-speed signals and prevent external electromagnetic interference from entering the high-speed assembly. The outer shielding layer is arranged on the outer side of the inner shielding layer, which further enhances the shielding effect and ensures that the high-speed assembly can work stably in a complex electromagnetic environment. 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.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] In actual application, the high-speed component 7 faces the dual challenges of internal high-speed signal leakage and external electromagnetic interference intrusion. The internal high-speed signal leakage may interfere with the surrounding electronic equipment and affect the overall stability of the system. The intrusion of external electromagnetic interference may cause data errors, performance degradation, and even failure of the high-speed component 7. To solve this problem, as shown in the technical solution, the present application provides the following technical solution: Figures 1-4 A split-resistant high-speed grounding shielding group connector is disclosed, The rear side of the shell 1 is provided with a tailstock 2, and the inside of the tailstock 2 is provided with an inner shell 3. The center of the inner shell 3 is provided with a connecting housing 8, and the connecting housing 8 is provided with high-speed components 7 arranged at equal intervals. A shielding mechanism is provided on the connecting housing 8 and located on the side of the high-speed components 7. The shielding mechanism includes an inner shielding layer 4 located at the center of the connecting housing 8. An outer shielding layer 5 is provided through the inner shielding layer 4 and located on the side of the inner shielding layer 4. The outer shielding layer 5 is provided in two groups 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. The side of the outer shielding layer 5 is provided with an outwardly arched auxiliary pressing material. Welding points 6 are provided through the outer shielding layer 5 and the two groups of inner shielding layers 4. The welding points 6 are symmetrically distributed about the center point of the connecting housing 8. The welding points 6 further improve the firmness between the outer shielding layer 5 and the two groups of inner shielding layers 4, ensuring the continuity and stability of the shielding.

[0026] The outer shielding layer 5 is arranged outside the inner shielding layer 4, and the layered design further enhances the shielding effect. The inner shielding layer 4 is made of stainless steel, which has good corrosion resistance and mechanical strength and can maintain stable performance in various harsh environmental conditions, 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 electrical conductivity and can more efficiently conduct electromagnetic interference. When external electromagnetic interference contacts the outer shielding layer 5, the high-conductivity copper can quickly introduce the interference current into the ground terminal, thereby reducing the influence 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 through the welding points 6, effectively avoiding the possibility of loosening and separation between the inner shielding layer 4 and the outer shielding layer 5. In the high-speed running working scene, the connector is often affected by vibration and external force, which may cause relative displacement between the inner shielding layer 4 and the outer shielding layer 5, thereby damaging the integrity of the shielding and reducing the shielding effect. The firm connection of the welding points 6 can ensure that the inner shielding layer 4 and the outer shielding layer 5 always maintain close contact, forming a continuous and stable shielding body that effectively prevents separation caused by vibration or external force, thereby ensuring the shielding effect of the connector. The symmetrical distribution of the welding points 6 can evenly distribute stress to the entire shielding mechanism, avoiding local stress concentration that may cause damage to the welding points 6 or deformation of the shielding layer, thereby further improving the stability and reliability of the connector.

[0027] Example Two: In order to further improve the stability between the inner shielding layer 4 and the outer shielding layer 5, a resisting mechanism is provided, as shown in the technical solutions of Figure 7 、 Figure 9 and Figure 11 , the present application provides the following technical solutions: a high-speed grounding shielding group connector that prevents separation, which discloses that the connecting shell 8 is provided with a resisting mechanism, and the resisting mechanism further limits the shielding mechanism through the position movement of the sliding rod 13. The resisting mechanism includes a sliding rod 13, which is slidingly connected to the connecting shell 8 and symmetrically arranged about the center point of the connecting shell 8. The sliding rod 13 is located outside the outer shielding layer 5, and the outer end of the sliding rod 13 is fixedly connected with a pull plate 9, which is located outside the connecting shell 8. The inner side of the pull plate 9 is fixedly connected with a friction block 11, and the outer side of the connecting shell 8 is provided with a butt joint groove 10 corresponding to the position of the friction block 11. The butt joint groove 10 is in communication with the installation groove of the outer shielding layer 5. When the pull plate 9 moves to one side of the connecting shell 8, the friction block 11 is butted into the butt joint groove 10, and the side of the friction block 11 is in contact with the side of the outer shielding layer 5. The friction block 11 can increase the friction force with the outer shielding layer 5, thereby preliminarily limiting the outer shielding layer 5.

[0028] 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.

[0029] 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.

[0030] The sliding rod 13 moves while the abutting rod 12 is driven by the sliding rod 13 and gradually moves from the initial position to the outside of the connecting shell 8, the blocking and limiting effect of the connecting shell 8 on the abutting rod 12 gradually disappears, the abutting rod 12 is connected with the torsion spring 14, when the connecting shell 8 no longer limits it, the torsion spring 14 starts to drive the abutting rod 12 to rotate by virtue of the elastic force, when the sliding rod 13 moves to a specific position, the lower end of the abutting rod 12 is accurately placed in the abutting grooves 15 corresponding to the upper and lower sides of the inner shielding layer 4, so that the abutting rod 12 can form a close cooperation relationship with the inner shielding layer 4 and the outer shielding layer 5 after entering the abutting grooves 15, effectively preventing the shielding mechanism from being separated during high-speed operation, providing a good electromagnetic shielding environment for the high-speed component 7, reducing the influence of external electromagnetic interference on high-speed signal transmission, thereby improving the quality and efficiency of signal transmission, meeting the needs of high-speed communication and data processing, the torsion spring 14 provides a stable restoring force for the abutting rod 12 through its elastic properties, when the abutting rod 12 is not subjected to external force, the torsion spring 14 can keep it in a specific position set in advance, thereby ensuring that the entire mechanism can maintain a stable structure form in static and dynamic conditions, the two groups of abutting rods 12 adopt the same direction abutting arrangement, so that the two groups of abutting rods 12 can simultaneously exert force on the inner shielding layer 4, forming a symmetrical and uniform clamping effect, so that the stress of the inner shielding layer 4 in each direction is more balanced, which can effectively resist external vibration, impact and other interference factors, further improving the stability of the inner shielding layer 4.

[0031] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
