Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a dense contact conductive mesh. Background Technology

[0002] New energy connection plugs are key components used for the transmission of electrical energy and signals between new energy devices (such as electric vehicles, photovoltaic systems, and energy storage devices), and must meet high safety, reliability, and compatibility requirements. In the field of new energy connection plugs, the conductive mesh, as a key component for realizing electrical energy / signal transmission, directly determines the conductivity and service life of the plug-in through its structural design.

[0003] Traditional conductive meshes often employ rigid contact structures, such as flat or pinhole conductive sheets. When mating with external sockets, they rely on a single contact point or a limited contact area to achieve conductive connection. Taking the DC charging interface of new energy vehicles as an example, when the vehicle vibrates during operation or the charging gun is impacted by external forces, the rigid contact structure is prone to displacement deviation, leading to increased contact resistance or even instantaneous power outage. Furthermore, the internal socket structure of traditional conductive meshes is mostly an open or semi-open design, lacking a limiting mechanism for the plug. For example, in the high-voltage connection system of energy storage battery clusters, the external plug is only initially positioned through a guide groove, and after insertion, it relies on gravity or slight friction to maintain contact. When electromagnetic vibrations or temperature changes occur during equipment operation, causing thermal expansion and contraction of materials, the plug is prone to axial loosening or radial displacement, thus affecting the stability of transmission.

[0004] Therefore, a dense contact conductive mesh is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a dense contact conductive mesh, which aims to solve the problems in the prior art.

[0008] A plug hole is provided at one end of a conductive body, and an installation hole is provided on the inner wall of the plug hole;

[0009] The second conductive body is connected to the end of the first conductive body, and the cross-sectional shape of the second conductive body is T-shaped.

[0010] A twill-patterned drum spring structure is sleeved on the outer surface of the conductive body two. The twill-patterned drum spring structure is used to ensure that the conductive body two is stably connected to the external socket.

[0011] A dense conductive mesh structure is disposed inside the mounting hole. The dense conductive mesh structure is used not only for conducting electricity, but also for ensuring a stable connection between the conductive body and the external plug.

[0013] Preferably, the dense conductive mesh structure includes two end rings and two arc-shaped spring plates. There are two end rings, which are symmetrically installed on the inner wall of the mounting hole.

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, a dense contact conductive mesh includes a conductive body 10, one end of which is fixedly connected to a conductive body 20 with a T-shaped cross-section. A zigzag drum spring structure 30 is sleeved on the outer surface of the conductive body 20 to ensure stable connection between the conductive body 20 and an external plug. One end of the conductive body 10 has a plug hole 101, and the inner wall of the plug hole 101 has a mounting hole. A dense conductive mesh structure 40 is arranged inside the mounting hole. The dense conductive mesh structure 40 is used not only for conducting electricity but also for ensuring stable connection between the conductive body 10 and the external plug.

[0028] During the use of this dense contact conductive mesh, the conductive body 20 is inserted into the interior of the external socket, and the conductive body 20 is fixed by the diagonal spring structure 30, which increases the contact area between the conductive body 20 and the external socket, ensuring the connection stability between the conductive body 20 and the external socket, and preventing the conductive body 20 from easily shifting position. Furthermore, the external plug is inserted into the interior of the plug hole 101, and the external plug is clamped and fixed by the dense conductive mesh structure 40, preventing the external plug from becoming loose or shifting, thereby ensuring the connection stability between the external plug and the dense conductive mesh structure 40.

[0029] It should be noted that both conductive body 10 and conductive body 20 are cylindrical in shape, and conductive body 10 and conductive body 20 are coaxial, ensuring the conductivity stability of conductive body 10 and conductive body 20.

[0030] The oblique-patterned drum spring structure 30 includes two end rings 31 coaxially sleeved on the outer surface of the conductive body 20. Multiple arc-shaped spring plates 32 are evenly connected to the opposite side of the two end rings 31. Each arc-shaped spring plate 32 is arranged in an oblique manner. Each arc-shaped spring plate 32 adopts an outward convex curved surface design. A contact protrusion 33 is fixedly connected to the outer surface of each arc-shaped spring plate 32. Multiple V-shaped slots are opened on the outer surface of the two end rings 31.

[0031] During the process of inserting the conductive body 20 into the external socket, multiple arc-shaped spring plates 32 will undergo elastic deformation. After the conductive body 20 is inserted into the external socket, the reaction force of the multiple arc-shaped spring plates 32 will cause the contact bumps 33 to fit tightly with the socket. The multiple contact bumps 33 can increase the contact pressure between the arc-shaped spring plates 32 and the external socket, thereby ensuring the connection stability between the conductive body 20 and the external socket. Furthermore, the contact bumps 33 can reduce contact resistance, reduce loss and interference during signal transmission, and ensure stable transmission of current or signal. The contact bumps 33 are made of wear-resistant material, which makes the contact bumps 33 more wear-resistant and greatly avoids the arc-shaped spring plates 32 from being subjected to friction, thereby extending the service life of the arc-shaped spring plates 32.

[0032] It should be noted that the outer diameter of end ring 31 is smaller than the maximum diameter of conductive body 20, and the outer diameter of end ring 31 is smaller than the diameter of conductive body 10. One end ring 31 is in contact with the end of conductive body 20, and the other end ring 31 is in contact with the end of conductive body 20. This ensures that the zigzag drum spring structure 30 will not shift position after being fitted onto conductive body 20, thus ensuring the stability of the zigzag drum spring structure 30. The maximum distance between the arc-shaped spring plate 32 and the central axis of end ring 31 is greater than the maximum radius of conductive body 20, allowing the arc-shaped spring plate 32 to contact the external socket and generate elastic deformation.

[0033] The dense conductive mesh structure 40 includes two end rings 41 installed on the inner wall of the mounting hole. Multiple arc-shaped spring plates 42 are evenly connected to the opposite side of the two end rings 41. Each arc-shaped spring plate 42 adopts a concave curved surface design, and the minimum distance between the arc-shaped spring plate 32 and the central axis of the end ring 41 is less than the radius of the end ring 41.

[0034] During the process of inserting the external plug into the plug hole 101, multiple arc-shaped spring plates 32 will undergo elastic deformation. After the external plug is inserted into the plug hole 101, the external plug can be clamped under the reaction force of the multiple arc-shaped spring plates 32, thereby ensuring the stability of the external plug and preventing the external plug from becoming loose or shifting.

[0035] The outer surface of the conductive body 10 is provided with at least one V-shaped groove 102. The V-shaped groove 102 increases the surface area of ​​the conductive body 10, which helps to accelerate the dissipation of heat through the air or contact interface and speeds up the heat dissipation of the conductive body 10. The conductive body 10 may generate thermal expansion and contraction stress under long-term load or temperature change. The V-shaped groove 102 can serve as a stress relief structure to reduce the risk of material fatigue or fracture caused by deformation and ensure the service life of the conductive body 10.

[0036] The end of the inner wall of the plug hole 101 is provided with a plug-in transition slope 103, which is used to allow the external plug to be smoothly inserted into the interior of the plug hole 101. The end of the conductive body 20 is provided with a plug-in transition fillet 201, which is used to allow the conductive body 20 to be smoothly inserted into the interior of the external socket.
