[0019] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0020] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.
[0021] In a specific embodiment, Figure 1-3 As shown, a large current contact electrode with adaptive surface deformation includes an electrode mounting base 1, a base fixing hole 2 is opened on the electrode mounting base 1, an electrode contact disk 3 is fixedly installed on the bottom of the electrode mounting base 1, a flexible buffer pad 4 is fixedly installed inside the electrode contact disk 3, and a flexible mesh conductive disk 5 is fixedly installed on the end of the flexible buffer pad 4 away from the electrode contact disk 3.
[0022] In this embodiment, the central axis of the base fixing hole 2 coincides with the central axis of the electrode mounting base 1, that is, the base fixing hole 2 is located at the center of the electrode mounting base 1. Specifically, a resistance increasing protrusion is fixedly installed on the inner wall of the base fixing hole 2.
[0023] In this embodiment, the electrode contact disk 3 is hollow inside and communicates with the base fixing hole 2, and the electrode of the electric device can be inserted through the base fixing hole 2 to contact with the flexible mesh conductive disk 5 for conduction. In other embodiments, an annular groove and a through hole communicating with the base fixing hole 2 are opened at the bottom of the electrode contact disk 3, and the flexible buffer pad 4 is fixedly installed in the annular groove.
[0024] The above-mentioned high-current contact electrode with adaptive surface deformation can be further optimized and / or improved according to actual needs:
[0025] The flexible buffer pad 4 is cylindrical, retractable and elastic. When the flexible buffer pad 4 and the flexible mesh conductive disk 5 are deformed by inserting an electrode of an electric device, a certain stress is maintained between the flexible mesh conductive disk 5 and the electrode of the electric device, so that the flexible mesh conductive disk 5 and the electrode of the electric device maintain stable contact and will not be disconnected. Specifically, the flexible buffer pad 4 is rubber.
[0026] The diameter of the side wall of the flexible mesh conductive disk 5 matches the diameter of the electrode contact disk 3, so that when the electrode of the non-useful electrical device is inserted, the tensile force of the flexible buffer pad 4 to restore the deformation pulls the flexible mesh conductive disk 5 to fit with the bottom of the electrode contact disk 3, so that the flexible buffer pad 4 is hidden inside the electrode contact disk 3. The bottom surface of the flexible mesh conductive disk 5 is mesh-shaped and has toughness and conductivity. Specifically, the bottom surface of the flexible mesh conductive disk 5 is copper, which has good toughness and conductivity, and can meet the toughness and conductivity functions required by the bottom surface of the flexible mesh conductive disk 5.
[0027] To sum up: the base is connected to the electrode of the electrical equipment through the fixing hole 2. When the contacts of the electrical equipment are in contact with each other, under the action of pressure, the flexible mesh conductive disk 5 will adaptively deform and adjust according to the deformation or wear condition of the contact point, so as to ensure reliable contact of the contact point with the maximum area. In this way, the purpose of ensuring reliable contact of the conductive contacts and ensuring reliable and stable operation of the electrical equipment is achieved. The internal flexible buffer pad 4 and the flexible mesh conductive disk 5 are used to maximize the contact area of the electrode surface under pressure. This not only ensures the stable operation of the high-current equipment, but also effectively reduces the probability of safety accidents such as fire caused by excessive heat caused by the contact point resistance.
[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
