[0002] When digital products or electrical appliances are connected to the power supply, they need to be connected to the mains with a USB socket or two-phase or three-phase electricity. However, since most USB sockets or two-phase or three-phase electricity are fixed on a plane and the plug is used flexibly, when the plug is plugged into the socket on the socket, the plug and the socket need to be aligned before plugging. At night, the operator cannot identify the position of the plug and the socket well, and there is a problem that the operator may insert the plug in reverse or it is difficult to dock the plug and the socket.

[0003] After searching, the authorization announcement number CN112382884A discloses an insertion device for extending the life of wiring and facilitating nighttime plugging, comprising a housing, a socket is arranged on the lower side of the housing, a magnet 1 is fixedly connected to the upper surface of the middle part of the socket, a plug is fixedly connected to the bottom of the housing, a metal rod is movably connected inside the plug, a magnet 2 is fixedly connected to the middle part of the metal rod, and a baffle is connected to the top of the metal rod through a connecting rod 1;

[0004] The above-mentioned insertion device that extends the life of the wiring and facilitates nighttime plugging, although it is easy to find the plugging position through the attraction between magnet 1 and magnet 2 during plugging, and the metal rod extends out of the baffle to achieve the effect of facilitating plugging at night, but in actual operation, since the middle part of the metal rod at the internal movable end of the plug is fixedly connected to magnet 2, and the upper surface of the middle part of the socket is fixedly connected to magnet 1, when the plug and the socket are plugged in at night, magnet 1 is located on the surface of the socket. The metal rod and magnet 1 on the surface of the socket are magnetically attracted, causing the metal rod to be unable to quickly align with the socket on the socket, and there is also a risk of magnetic attraction of the metal rod deviating from the socket, thereby causing the plug and the socket to be unable to be quickly plugged in;

[0005] Therefore, the utility model provides a plug assembly which is convenient for plugging at night. Utility Model Content

[0006] The purpose of the utility model is to provide a plug assembly which is convenient for plugging at night, so as to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The plug assembly is convenient for nighttime plugging. The socket is provided with a guide groove arranged at the outer edge of the socket, and the plugging end of the plug is provided with a guide piece located at the outer edge of the plug connector. The guide piece is retracted into the receiving groove as the plug and the socket are plugged in. When the plug is plugged in the socket, the guide piece and the guide groove cooperate with each other for magnetic guidance, so that after the guide piece and the guide groove cooperate and dock, the plug connector located inside the guide piece and the guide groove corresponds to the socket. The plug moves toward the socket position, and the guide piece is stored in the receiving groove as the plug connector on the plug is plugged into the socket on the socket. At the same time, the end of the guide piece is located at the end of the receiving groove, and the limit piece on the plug limits the end of the guide piece, so that the guide piece is fixed in the receiving groove, so as to achieve the convenience of plugging and using the plug and the socket at night while maintaining the stability of the plugging and connecting of the plug and the socket.

[0021] The guide plate on the guide member is arranged on the outer edge of the plug connector through a supporting spring. After the plug is removed from the socket, the pull block is used to move the movable rod upward so that the pin block at the end of the movable rod is moved out of the limiting hole, thereby achieving the purpose of eliminating the force of the limiting member on the guide member to be limited in the receiving groove. The guide plate is supported again by the supporting spring to support the plug end protruding from the plug, thereby protecting the plug connector. BRIEF DESCRIPTION OF THE DRAWINGS
