What is the role of the protective door design on Power Strips, and how to use it correctly?

In our daily life, Power Strips are an indispensable electrical accessory. The protective door design on the power strip provides an important guarantee for our electrical safety. So, what is the role of the protective door design on the power strip? And how to use it correctly?
First of all, the protective door design on the power strip can effectively prevent children from electric shock. Children are curious and often insert their fingers or other objects into the sockets of the power strip, which can easily lead to electric shock accidents. The design of the protective door can close the socket when the socket is not plugged in, preventing children from contacting the conductive parts inside the socket, thereby effectively avoiding electric shock accidents.
Secondly, the protective door design can also prevent dust and debris from entering the socket. In daily use, the power strip is often exposed to the air, and dust and debris are easily accumulated. If dust and debris enter the socket, it may cause poor contact of the power strip, and even cause safety accidents such as fire. The design of the protective door can effectively prevent dust and debris from entering the socket, keeping the socket clean and in good contact.
So, how to use the protective door on the power strip correctly?
First, when inserting the plug, make sure that the shape and size of the plug match the socket of the power strip. If the plug is too large or too small, the protective door may not open normally, affecting the insertion of the plug.
Second, when inserting the plug, apply force evenly and avoid excessive or light force. Excessive force may damage the protective door, and too light force may not open the protective door.
Third, when using the power strip, avoid inserting too many electrical plugs into the same power strip to avoid exceeding the load capacity of the power strip and causing safety accidents such as fire.
Fourth, when the power strip is not in use, unplug the plug in time and place the power strip in a dry and ventilated place to prevent the power strip from getting damp or other damage.
