because when electricity pass through the plug ,it produces heat and this type of plastic doesn't melt
Answer for UK Electrical SystemThe terminals of British electrical socket outlets are protected by shutters that are opened by the earth pin of the inserted plug. Many British electrical engineers believe that so-called 'child proof' socket protectors are unnecessary and, in fact, may actually be dangerous. These protectors are held in place by a plastic 'earth terminal' which, if inserted upside down, will actually open the shutters, making the terminals accessible to children's prying fingers. So, the general consensus is that these socket protectors should NOT be used.
You typically plug electrical devices into a socket to supply power to them. It is important to use compatible plugs and ensure that the voltage requirements match to avoid damage to the device or electrical hazards.
A socket is a receptacle that allows an electrical plug to connect to an electrical system. Inside a socket, you will typically find metal contacts that make contact with the prongs of the plug to establish an electrical connection. There may also be wiring and insulation materials to protect and maintain the connection.
A neutral wire in a socket circuit is used to complete the electrical circuit and provide a return path for current to flow back to the electrical panel. It helps balance the electrical load in the circuit and is essential for the safe operation of electrical devices.
The electrical power that you use from the utility company has to be metered. This is done with a plug in watt meter. The meter socket is what holds the electrical watt meter. It is this meter that the meter reader reads to give you your monthly billing for the electricity that you used.
So that when you plug in something you don't get shocked.
Electrical energy comes out of a wall socket.
It may be a plastic, or it may be Bakelite (a phenolic resin product) but either way, it is there because is is not a conductor, but an insulator. It protects you, the user, from electrical shock.
Electrical energy comes out of a wall socket.
Electric energy is used for a wall socket, which comes from the electrical grid and is converted into usable electricity to power devices and appliances.

By plugging its cord into an electrical socket.
To replace an electrical socket, first turn off the power to the socket at the circuit breaker. Remove the cover plate and unscrew the socket from the wall. Disconnect the wires from the old socket and connect them to the new socket in the same way. Screw the new socket into place and replace the cover plate. Turn the power back on at the circuit breaker and test the new socket to ensure it is working properly.
To change an electrical socket, first turn off the power to the circuit at the breaker box. Remove the cover plate and unscrew the socket from the wall. Disconnect the wires from the old socket and connect them to the new socket, following the manufacturer's instructions. Screw the new socket into place and replace the cover plate. Turn the power back on and test the socket to ensure it is working properly.
In America, a socket is commonly referred to as an "electrical outlet" or "power outlet." It is the point where electrical devices can be plugged in to receive power. Additionally, the term "receptacle" is also used, particularly in electrical and construction contexts.

Its function is to supply electrical power via a plug that is plugged into it to supply an appliance.
