[0002] PoE power refers to the power source in the PoE power supply system. The working principle of PoE power is to convert AC power into DC power and transmit power and data signals to network devices through Ethernet cables. The power of PoE power determines how many PD devices the PSE can power at the same time. In the prior art, an anti-drop device is usually added to the interface of the PoE power cable to prevent the cable from being separated from the socket, affecting the normal use of the equipment and shortening the service life of the equipment, and to prevent the cable interface from falling off, causing potential hazards such as electric shock and fire to operators, so as to ensure the safety of the cable interface.

[0003] A POE power supply with a cable anti-drop interface is disclosed in the Chinese utility model patent application disclosure specification CN218472444U. The POE power supply with the cable anti-drop interface prevents the cable at the interface from moving and falling off easily, thereby avoiding damage to the equipment caused by cable falling off and power outage during the use of the POE power supply, ensuring that the cable at the cable interface is not easily disconnected, and ensuring safe use. However, the elasticity of the first return spring and the second return spring of the POE power supply with the cable anti-drop interface will decrease after long-term use. In order to ensure stable fixing work, the first return spring and the second return spring need to be replaced. The first return spring and the second return spring are both fixedly connected, which makes the operation of replacing the first return spring and the second return spring more troublesome. Therefore, a POE power supply with a cable anti-drop interface is needed to solve the above problem. Utility Model Content
