Description

Technical Field

[0001] This utility model relates to a power supply protection device, specifically a protection device for a power output copper busbar. Background Technology

[0002] "U"-based standard modular power supplies are widely used in the power electronics industry. Generally, after installation, they require an external power supply to function properly. For high-current power supplies, larger cables are typically used, and protective devices are installed at the input or output points to ensure safety during use.

[0003] Existing protective devices are mostly used for overall protection of power supplies. For example, Chinese utility model patent CN 216531060 U discloses a protective device for communication switching power supplies, which installs the power supply entirely inside a protective box. A cooling fan is installed on the support frame inside the protective box, and ventilation holes are opened at corresponding positions on the protective box. Therefore, it not only isolates and protects the power supply but also ensures its normal operation. However, the overall structure of this type of protective device is relatively large. When the power supply fails, the protective box must be disassembled to inspect or repair the power supply before it can be reassembled to restore its protective function. This method makes the installation or disassembly process cumbersome and time-consuming. In addition, this type of protective device requires the input and output cables to be installed before the protective box is installed. If the cable connection is incorrect, the protective box must be removed first to adjust the cable connection. Therefore, this also leads to the problem of a cumbersome and time-consuming installation or disassembly process. Utility Model Content
