Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with a detachable plug. Background Art

[0002] A power adapter, also known as a power converter, is a power conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer, and a rectifier circuit. A power adapter is a device that can convert alternating current into direct current. Its output voltage and current can be adjusted according to different device requirements.

[0003] At present, the plug of the power adapter may be damaged due to various reasons, such as too many plugging and unplugging times, external force impact, etc. The damaged plug not only affects the normal use of the power adapter, but also may cause safety hazards. At this time, it is necessary to promptly remove and replace the new plug. When the existing power adapter and plug are in use, the slider moves within the range of the slide groove. The slider drives the first power connector to extend and retract, and cooperates with the rotation of the second power connector to drive the limit block to rotate inside the rotating groove so that the power connector can be adapted for use with different types of sockets. However, when the existing power adapter and plug are in use, the overall structure of the power adapter becomes complicated due to the need to design complex structures such as the slide groove, slider, and rotating groove, and to achieve precise coordination of these structures. Once a component is damaged, the entire power adapter may need to be replaced, thereby increasing the failure rate and maintenance cost. In addition, the slider and rotating mechanism may accidentally extend or rotate when not in use, and the exposed metal parts may cause electric shock hazards.

[0004] Therefore, it is necessary to provide a new detachable plug power adapter to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a power adapter with a detachable plug.

[0006] The utility model provides a detachable plug power adapter comprising an adapter body and a plug body, wherein the adapter body and the plug body are connected via a connecting device;

[0007] The connecting device includes a placement block and a limiting assembly. The placement block is fixedly connected to one end of the adapter body, and a plurality of limiting holes are opened on the placement block. The inner walls of the plurality of limiting holes are movably connected to spheres. An elastic member is fixedly connected to the placement block, and the end of the elastic member away from the placement block is fixedly connected to a movable block. The movable block is sleeved on the outer surface of the placement block, and the limiting assembly is movably connected to the inner wall of the placement block.

[0008] Preferably, the limiting assembly includes an insert block, which is fixedly connected to one end of the plug body and movably connected to the inner wall of the placement block.

[0009] Preferably, one end of the plug body away from the plug block is fixedly connected to a plurality of connectors.

[0010] Preferably, the elastic member is a compression spring, the compression spring is fixedly connected to the placement block, and one end of the compression spring away from the placement block is fixedly connected to one end of the movable block.

[0011] Preferably, the insert block is provided with a groove matching the sphere.

[0012] Preferably, a wire is provided on one side of the adapter body.

[0013] Compared with related technologies, the detachable plug power adapter provided by the present invention has the following beneficial effects:

[0014] The plug-detachable power adapter provided by the present invention, in specific implementation, when it is necessary to disassemble the plug, first slide the movable block on the outer surface of the placement block toward the adapter body, and the movable block squeezes the compression spring during movement. When the movable block loses its restriction on the sphere, the sphere leaves the groove on the surface of the plug block, and the sphere loses its restriction on the plug block. Then the plug block is taken out, and the plug block drives the plug body and the connector to separate from the placement block. The movable block is released, and under the action of the compression spring, the movable block returns to its initial position. The power adapter plug is disassembled by the above mechanism, which increases the probability of failure rate and maintenance cost, and reduces the possibility that the slider and the rotating mechanism may accidentally extend or rotate when not in use, and the exposed metal parts may cause electric shock hazards.
