Those skilled in the art will understand that users or manufacturers may use different names or terms to refer to the same component or part. This specification and claims do not distinguish components or parts by differences in name, but rather by differences in function. The terms "comprising" and "including" used throughout the specification and claims are open-ended and should be interpreted as "including but not limited to". Furthermore, the term "connection" here includes any direct and indirect electrical connection means. Indirect electrical connection means include connections via other means.

[0054] It should be noted that in the description of this utility model, the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship or parameters are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, a specific size, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0055] Existing E-polar conductive components have the following drawbacks: high contact resistance, resulting in poor contact performance; poor wear resistance, leading to a short service life; unstable contact, making it prone to poor contact; inability to monitor status in real time, making it difficult to detect potential faults in a timely manner; and difficulty in cleaning, affecting performance.

[0056] To address the aforementioned problems, this utility model provides an improved E-polar conductive element 1, such as... Figures 1 to 7 As shown.

[0057] In some embodiments, such as Figures 1 to 3 As shown, the E-polar conductive component 1 includes an upper cylindrical portion 10 and a lower cuboid portion 11. The diameter D1 of the cylindrical portion 10 is smaller than the width W of the cuboid portion 11, the length L1 of the cylindrical portion 10 is smaller than the length L2 of the cuboid portion 11, and the thickness of the cuboid portion 11 is smaller than the diameter D1 of the cylindrical portion 10.

[0058] Existing track power outlets generally use a rotary adapter 2, as shown in Figure 4 , the rotary adapter 2 comprises a base 21 and a rotary housing 20, the rotary housing 20 is rotatably sleeved on the base 21, a plug connector 22 is fixedly connected below the base 21, and the plug connector 22 is plugged into a conductive track for power taking. An E-electrode conductive member 1 penetrates the base 21 and the plug connector 22 in a direction perpendicular to the base 21, the E-electrode conductive member 1 is located between an N-electrode conductive sheet and an L-electrode conductive sheet (not shown in the figure), and the N-electrode conductive sheet and the L-electrode conductive sheet are asymmetrically arranged relative to the E-electrode conductive member 1, but the present invention is not limited thereto. When the plug connector 22 is inserted into the conductive track, the E-electrode conductive member 1 is configured to be connected to a ground wire in the conductive track, so as to prevent electric leakage of electric appliances and electric shock hazards, and ensure power consumption safety. Further, the cylindrical portion 10 of the E-electrode conductive member 1 is located in the rotary housing 20, and the rectangular parallelepiped portion 11 extends out of the plug connector 22. The cylindrical portion 10 at the upper part of the E-electrode conductive member 1 can provide better rotary contact, increase the contact area and reduce wear; the lower flat rectangular parallelepiped portion 11 ensures stable connection during insertion and saves space.

[0059] In some embodiments, an annular boss 12 is provided at the connection between the cylindrical portion 10 and the rectangular parallelepiped portion 11, the diameter D2 of the annular boss 12 is larger than the diameter D1 of the cylindrical portion 10 and smaller than the width W of the rectangular parallelepiped portion 11, that is, D1<D2<W. As shown in Figure 8 , Figure 9 , the upper part of the cylindrical portion 10 is sleeved with an E-electrode jack 30 of an outlet (e.g., a track outlet), the lower part is sleeved with a spring 40, and the annular boss 12 fixes the spring 40, so that flexible contact can be provided and the service life of the product can be improved. In other embodiments, the annular boss 12 can be replaced with an annular groove (not shown in the figure).

[0060] In some embodiments, the base material of the E-electrode conductive member 1 is C5191 phosphor bronze, with an elastic modulus ≥ 110 GPa and a conductivity of 22% IACS (International Annealed Copper Standard). As Figure 5 , the outer side of the E-electrode conductive member 1 is provided with a composite plating layer 14, the composite plating layer 14 comprises an inner plating layer 140 and an outer plating layer 141, wherein the inner plating layer 140 is electroless nickel plating of 3 microns, the outer plating layer 141 is hard gold of 0.5 microns, Vickers Hardness (HV) ≥ 300 kgf / mm² (kilogram-force per square millimeter), so that the contact resistance is reduced and the wear resistance life is improved.

[0061] In some embodiments, as shown in Figure 6The cylindrical part 10 adopts a segmented silver alloy slip ring structure, which is divided into multiple slip rings 100 with an arc length of 15mm. The adjacent slip rings 100 are spaced 5° apart to increase the contact area and reduce the fluctuation of rotational contact resistance. The bottom end of the cuboid part 11 is equipped with a bidirectional spring pin 13. The bidirectional spring pin 13 has a stroke of 0.5mm and a spring force of 1.2N to achieve self-compensation of the plug-in connection and allow for ±2mm installation deviation.

[0062] In some embodiments, to improve the stress resistance of the E-polar conductive component 1, multiple U-shaped stress buffer grooves 110 are provided on both sides of the bottom of the cuboid portion 11, with a radius of, for example, 0.3 mm and a depth of 0.5 mm. This can improve fatigue life. This invention uses two U-shaped stress buffer grooves 110 on the side as an example for illustration, but is not limited thereto. For example, U-shaped stress buffer grooves 110 can also be provided on the bottom end face of the cuboid portion 11. In other embodiments, the stress buffer grooves can also be V-shaped.

[0063] In some embodiments, the surface of the cuboid portion 11 is laser-engraved with sharkskin microgrooves 111, with a depth of, for example, 20 micrometers and a spacing of 50 micrometers, to reduce insertion and extraction force.

[0064] In some embodiments, the E-polar conductive element 1 integrates an intelligent monitoring module, such as a thin-film strain gauge 15 built into the cylindrical portion 10 for monitoring contact pressure.

[0065] In some embodiments, the cuboid portion 11 integrates a wireless temperature sensor 16, employing NTC (Negative Temperature Coefficient Thermistor) + Bluetooth 5.0 technology, with an accuracy of ±0.5 degrees Celsius, transmitting grounding resistance and contact temperature to the client (e.g., a mobile phone) in real time. Simultaneously, a ceramic scraper (not shown) is installed inside the rotating housing of the track socket at the slide rail that contacts the cylindrical portion 10, automatically cleaning the slide rail surface after each rotation. The space between the slide rails is filled with an arc-quenching colloid, resistant to 150 degrees Celsius, with a CTI (Comparative Tracking Index) ≥600 volts, suppressing arc generation.

[0066] In some embodiments, such as Figure 7 As shown, both sides 112 of the cuboid portion 11 are arc-shaped to reduce friction when the E-polar conductive component 1 is inserted, removed, or moved.

[0067] The E-polar conductive element 1 of this invention is applicable not only to track sockets but also to ordinary sockets and industrial sockets. Specifically, when applied to ordinary sockets, the socket structure needs to be adjusted to include a guide groove corresponding to the cuboid portion below the E-polar conductive element 1. When applied to industrial sockets, the substrate of the E-polar conductive element 1 can be C17200 beryllium copper or surface-plated with silver to increase thickness and reduce contact resistance.

[0068] In summary, this invention reduces the contact resistance of the E-pole conductive component through a composite coating design, thereby improving wear resistance and extending service life. The use of a segmented silver alloy slip ring structure, a U-shaped stress buffer groove, and a bidirectional spring pin 13 increases the contact area of ​​the E-pole conductive component, improves contact stability, reduces contact resistance fluctuations, achieves self-compensation for insertion, improves fatigue life, and reduces insertion and extraction force. The integrated intelligent monitoring module enables real-time monitoring of the contact pressure, contact temperature, and grounding resistance of the E-pole conductive component, facilitating timely detection of potential faults. Furthermore, the self-cleaning mechanism of the ceramic scraper automatically cleans the slide rail surface, suppresses arc generation, and improves the performance of the E-pole conductive component.

[0069] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms fall within the protection scope of the present invention.
