In the following description, a detailed description of known components other than the main components will be omitted.

The grounding type power plug 100 is connected to the adapter 200 to electrically connect the adapter 300 and the adapter 200 to ground the electronic device connected to the adapter 200, As shown in FIG.

For this purpose, the ground terminal 110 may be formed in the ground terminal groove 111 provided on the rear surface of the ground type power plug 100. Here, the ground terminal 110 may be a metal terminal made of a conductor such as metal, particularly copper or a copper alloy.

Here, the ground terminal groove 111 can be slidably engaged with the ground terminal protrusion 210 formed at the end of the grounding cord of the adapter 200. At this time, the ground terminal groove 111 may include a sliding rail 112 for guiding the joining direction of the ground terminal protrusion 210 so that the ground terminal protrusion 210 in the form of a disk slides inward.

4 showing a rear view of a grounded power plug 100 according to an embodiment of the present invention, a ground terminal protrusion 210 in the form of a disk is inserted into a ground terminal groove 111, The protrusion 210 'may move along the sliding rail 112 to engage with the ground terminal groove 111.

The ground terminal 110 formed in the ground terminal groove 111 may slide into the ground terminal groove 111 and be in close contact with the ground terminal protrusion 210 '

That is, one end of the ground terminal 110 may be electrically connected to the ground terminal protrusion 210 'while the ground terminal groove 111 and the ground terminal protrusion 210' are slidingly coupled.

Here, the ground terminal protrusion 210 may be a metal protrusion such as a metal, particularly, a metal protrusion made of copper or a copper alloy.

The power terminal 120 may be formed inside the power socket 121 provided on the back surface of the ground type power plug 100. Here, the power supply terminal 120 may be a pair of metal terminals made of a conductor such as metal, particularly copper or a copper alloy.
