Description

Technical Field

[0001] The utility model belongs to the field of electronic product charging, and particularly relates to a charging plug with a protection structure. Background Art

[0002] The charger adopts high-frequency power technology and applies advanced intelligent dynamic adjustment charging technology. The industrial frequency machine is designed based on the traditional analog circuit principle. The internal power devices of the machine are relatively large. Generally, there is a small noise when operating with a large load, but this model has stronger resistance in harsh power grid environment conditions, and its reliability and stability are stronger than those of the high-frequency machine.

[0003] Some charging plugs with protection structures have been specially developed in the prior art. For example, the Chinese patent with the publication number of "CN211908415U" discloses "a charger with a protection structure". Through the protection structure, when the charging plug is pulled out from the jack on the socket, the rectangular protection frame automatically returns to its original position, and the charging plug will be in a sealed state, avoiding damage to the charging plug when the charger collides, and at the same time avoiding the influence of dust, moisture, etc. on the charging plug to varying degrees, achieving the protection effect.

[0004] Although through the above problems, when the charging plug is pulled out from the jack on the socket, the rectangular protection frame can automatically return to its original position through the protection structure to achieve the protection effect, but in actual use, the rectangular cover needs to be removed, and there is no effective structure to store the rectangular cover when it is removed, which will lead to the loss of the rectangular cover. Once the rectangular cover is lost, the rectangular protection frame can only protect the plug on both sides, but the head end position of the plug cannot be effectively protected, adding trouble in use.
