Technical Field

[0001] The utility model relates to the technical field of adapters, and particularly relates to a high-voltage-resistant power adapter. Background Art

[0002] A high-voltage-resistant power adapter is a device that converts power into the required voltage and current. It has a high voltage resistance ability, usually referring to its ability to withstand a high input voltage without being damaged or malfunctioning. Such power adapters are widely used in various occasions that require stable and reliable power supply. Especially in complex or harsh electrical environments, high-voltage-resistant power adapters play an important role in multiple fields, including the consumer electronics field (such as mobile phones, tablets, laptops, etc.), the industrial control and automation field (such as factory automation production lines, robot controllers, etc.), the power system (such as relays, transformers, etc.). In these fields, high-voltage-resistant power adapters provide stable and reliable power supply for equipment, ensuring the normal operation of the equipment and extending its service life.

[0003] A power adapter with a publication number of CN216354888U, which relates to the technical field of power supplies. The power adapter includes a housing, an upper cover, and a plug. The housing and the upper cover are connected in an opposing manner; one end of the plug is provided with a pin, the upper cover is provided with a plug hole, the plug is inserted into the plug hole, the pin is bent, and the bent end of the pin abuts against the upper cover. The power adapter provided by the utility model, by providing a pin on the plug and abutting the pin against the upper cover, enables the bent end of the pin to closely abut against the surface of the upper cover when the plug is subjected to an external pulling force, thereby preventing the plug from disengaging from the upper cover, enhancing the connection stability and reliability between the plug and the housing, and also improving the strength and safety performance of the power adapter. In the prior art, the adapter generates a high amount of heat during operation and needs to effectively dissipate the heat to prevent the adapter from overheating. For this reason, we propose a high-voltage-resistant power adapter. Summary of the Utility Model
