Description

Technical Field

[0001] This utility model relates to the field of flexible connection technology, specifically a copper strip flexible connection for a charging pile. Background Technology

[0002] With the rapid development of the electric vehicle market, charging piles, as an important supporting facility for electric vehicles, are receiving increasing attention for their performance and reliability. Inside the charging pile, flexible connections used to connect different components play a crucial role. In particular, copper strip flexible connections in charging piles are widely used due to their excellent conductivity and mechanical flexibility. However, in practical use, traditional copper strip flexible connections in charging piles have some significant problems.

[0003] Traditional charging pile copper strip flexible connections typically consist of a copper strip body, fixed sections at both ends of the copper strip body, and insulating sealing sleeves fitted onto the copper strip body. While this structure can meet the basic requirements for current transmission to some extent, its protective measures are still insufficient. Specifically, the assembly between the insulating sealing sleeve and the copper strip body often leaves a certain gap, failing to achieve a good seal. These gaps provide pathways for dust, moisture, and other impurities from the external environment to enter. Especially for charging piles used outdoors or in harsh environments, this design flaw can lead to serious consequences, such as poor electrical contact and accelerated corrosion, thereby affecting the overall performance and lifespan of the charging pile.

[0004] Based on the above background, this patent proposes an improved copper strip flexible connection for charging piles. Utility Model Content

A sealing step one is provided on one end of the copper strip body near the fixed section, and a sealing step two is provided on the inner wall of the insulating sealing sleeve. After the insulating sealing sleeve is fitted onto the copper strip body, the sealing step one and the sealing step two are fitted together, and cable tie grooves for binding the elastic cable tie are provided at both ends of the insulating sealing sleeve.

[0007] Furthermore, a ring of fitting groove is provided on one side surface of the sealing step one, and a fitting step is provided on the sealing step two to fit into the aforementioned fitting groove.

[0008] Furthermore, the fixing section is provided with several stress relief grooves at intervals on one end of the copper strip body.

Compared with the situation that impurities easily enter due to the existence of gap in the prior art, the sealing performance of the copper belt flexible connection is significantly improved, and the copper belt body inside is better protected.

[0015] 2. Enhance the connection stability: the elastic band groove for bundling the elastic band is arranged at both ends of the insulation seal sleeve, and the both ends are bundled tightly by using the elastic band, which further enhances the connection tightness between the insulation seal sleeve and the copper belt body.

[0016] 3. Improve the conductivity and service life: since the entry of dust, water and other impurities is effectively prevented, the influence of dust accumulation on the surface of copper belt on the conductivity is avoided, and the problems of oxidation and corrosion of copper belt caused by water are avoided, thereby ensuring the good conductivity of the copper belt body, improving the efficiency and stability of power transmission. At the same time, the damage of copper belt caused by impurity erosion is reduced, the service life of copper belt flexible connection is prolonged, the maintenance cost and replacement frequency of equipment are reduced, which is of great significance to the long-term stable operation of power system and other related equipment.

[0026] This utility model provides a copper strip flexible connection for a charging pile.

[0027] In this embodiment, refer to Figures 1-5The copper strip flexible connector of the charging pile includes a copper strip body 1, fixed sections 2 located at both ends of the copper strip body 1, and an insulating sealing sleeve 3 fitted on the copper strip body. It also includes an elastic cable tie 4. A sealing step 5 is provided on one end of the copper strip body near the fixed section. A sealing step 6 is provided on the inner wall of the insulating sealing sleeve. After the insulating sealing sleeve is fitted on the copper strip body, the sealing step 5 and the sealing step 6 are fitted together. Cable tie grooves 7 for binding the elastic cable tie are provided on both ends of the insulating sealing sleeve.

[0028] In the above technical solution, by setting elastic cable ties and providing a sealing step one on the copper strip body and a sealing step two on the inner wall of the insulating sealing sleeve, the sealing step one and sealing step two fit snugly after the insulating sealing sleeve is fitted onto the copper strip body. Cable tie grooves are provided at both ends of the insulating sealing sleeve for securing the elastic cable ties. This structural design effectively prevents dust, water, and other impurities from entering through the connection between the insulating sealing sleeve and the copper strip body, improving the sealing performance of the copper strip flexible connection, protecting the copper strip body from external impurities, and ensuring its good conductivity. Furthermore, the elastic cable ties further enhance the connection stability between the insulating sealing sleeve and the copper strip body, preventing displacement or loosening of the insulating sealing sleeve during use, ensuring the overall reliability of the copper strip flexible connection structure, extending its service life, and improving the stability and safety of the charging pile during operation.

[0029] Specifically, a ring of fitting groove 8 is provided on one side surface of the sealing step one, and a fitting step 9 is provided on the sealing step two to fit into the fitting groove.

[0030] In this embodiment, a fitting groove is provided on one side surface of the sealing step one, and a fitting step is provided on the sealing step two to fit into the fitting groove. This fitting structure further enhances the tightness of the fit between the sealing step one and the sealing step two, resulting in a superior sealing effect. Through the cooperation of the fitting groove and the fitting step, the entry of impurities such as dust and water can be better prevented, further protecting the copper strip body.

[0031] Specifically, the fixing section is provided with several stress relief grooves 10 at intervals on one end of the copper strip body.

[0032] In this embodiment, a plurality of stress relief grooves are provided at intervals on one end of the fixed section located on the copper strip body. The stress relief grooves can effectively release the stress generated by external forces such as tension, compression or vibration during the use of the copper strip flexible connector, and avoid stress concentration in a certain part of the copper strip. This can prevent the copper strip from deforming, breaking or other damage due to stress concentration, improve the fatigue resistance and mechanical strength of the copper strip flexible connector, and extend its service life.

[0033] Specifically, the length of the stress relief groove is 1 / 3 to 1 / 2 of the length of the fixed section.

[0034] In this embodiment, the length of the stress relief groove is 1 / 3 to 1 / 2 of the length of the fixed section.
