The protection door of the two-pole and three-pole socket mainly functions to prevent accidental electric shock, and therefore the protection door is also an important safety component of the two-pole and three-pole socket. The function of the spring is mainly to reset the protection door to shield the socket after the plug is pulled out, preventing the user from inserting a small sharp object into the socket and contacting the live part to cause electric shock risk. Therefore, the correct assembly of the protection door and the spring is a very important link for the safety performance of the product in the later use.
