Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with a passive heat dissipation function. Background Art

[0002] The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output. It can be divided into wall-mounted and desktop types according to the connection method. It is widely used in security cameras, set-top boxes, routers, light strips, massagers and other equipment.

[0003] Existing power adapters usually need to be connected to devices with adapter cables. Adapter cables are usually connected to the power adapter in a pluggable manner, and the stability of the connection is not very good. During long-term use, the two are prone to loosening, causing abnormal power supply. Under external force, the two may even fall off, causing power supply interruption to the device, thereby affecting the normal use of the device. In view of this, we propose a power adapter with passive heat dissipation function. Utility Model Content

After the device adapter cable is connected to the power adapter main body 1, the top plate structure 3 is pulled against the docking head of the adapter cable by the elastic telescopic structure 2, so that the adapter cable and the power adapter main body 1 can be firmly connected, and it is not easy to loosen even after long-term use or external force. Therefore, the utility model can ensure the firmness of the connection between the power adapter main body 1 and the adapter cable, and ensure normal power supply to the device.

[0025] Specifically, the elastic telescopic structure 2 includes a sleeve 201, which is arranged on the power adapter body 1. An insertion rod 203 is inserted into one end of the sleeve 201, and a spring 202 is arranged between the insertion rod 203 and the opposite side of the inner cavity of the sleeve 201. With the cooperation of the spring 202, the insertion rod 203 can be driven to reset, so that the top plate structure 3 can be pressed against the docking head of the adapter cable.

[0026] Furthermore, the port of the sleeve 201 is T-shaped, and the end of the insertion rod 203 located inside the sleeve 201 is T-shaped, and a hand-held frame 204 is arranged at the end of the insertion rod 203 facing away from the sleeve 201. The port of the T-shaped sleeve 201 and the end of the T-shaped insertion rod 203 cooperate to ensure a limiting effect and prevent the two from detaching. The hand-held frame 204 is convenient for personnel to hold and pull the insertion rod 203.
