The plug 100 according to the present invention, unlike the conventional plug, projects outward on both sides while the two plug pins 130 are positioned on a straight line. 2 is a sectional view showing the inside of the plug 100 according to the present invention. The plug 100 includes a main body 110 and an end portion of the main body 110, And a pair of plug pins 130 electrically connected to the distal end. The plug pin 130 is located slightly above the bottom surface of the plug body 110. The plug main body 110 has a shape in which the cross section in the horizontal direction is circular.

On the upper side of the main body 110 of the plug 100, a knob 140 protrudes sideways so as to easily hold the plug 100 and rotate the plug.

The receptacle 200 is formed with a circular insertion groove 210 having a size such that the lower end of the plug 100 is tightly fitted and the plug pin 130 can pass through when the plug 100 is inserted into the receptacle 200 A pair of pin holes 220 communicating with the insertion groove 210 are formed symmetrically with respect to the center of the insertion groove 210.

5A and 5B, and 6A and 6B, a pin guide space (not shown) is formed in the periphery of the insertion groove 210 of the receptacle 200 and is long in the horizontal direction and has side walls in the direction of the insertion groove 210 opened 230 are formed.

A safety slide 300 is rotatably installed in a circumferential groove between the insertion groove 210 and the pin guide space 230. The safety slide 300 is configured to have an outer diameter slightly larger than the diameter of the insertion groove 210 so that it can not easily escape out. The safety slide 300 has a thickness that can not fit in the pin guide space 230 and has a circular ring shape as shown in Fig. At the upper end of the safety slide 300, two engagement grooves 310 are formed at intervals of 180 degrees. The latching groove 310 has a size and shape that can be inserted and spanned by the plug pin 130.

6A and 6B, a spring 400 is coupled between the lower end of the safety slide 300 and the main body 110 so that the plug pin 130 is inserted into the safety slide 300 as shown in FIG. 6B, The spring 400 is elongated. 6A, when the plug 100 is pulled out and the plug pin 130 does not push the safety slide 300, the safety slide 300 is moved by the force of the spring 400, And moves to a position where the hole 220 is present.

As shown in Figs. 5A and 5B and Figs. 6A and 6B, the pin guide space 230 is pierced in a clockwise direction and a counterclockwise direction with respect to the top view from the space directly communicating with the pin hole 220 have. A connection terminal 240 is provided in the ceiling portion and the bottom portion of the relatively opened space of the space between the pin guide hole 230 of the pin guide space 230 and the space adjacent to the pin hole 220.
