In addition, although the plug socket 10 has been exposed to use by exposing outside the wall or pillar, it is easily understood that the plug socket 10 may use a recessed type embedded in the wall or pillar.

2 and 3, a timer 50 is provided in the mounting hole 40 of the case 11. The timer 50 is set at an arbitrary time by the operation of the knob 51, and the timer 50 is rotated by the operation of a general spiral spring and a gear train (not shown) during any set time. 52) is rotated.

Meanwhile, first and second rotary cams 60 and 70 are mounted on the rotation shaft 52 of the timer 50 at predetermined intervals up and down, respectively, and the first and second rotary cams 60 and 70, respectively. Blocking grooves 61 and 71 are formed on one side of the outer circumferential surface.

In addition, the timer 50 rotates the first and second levers 65 and 75 about the shafts 66 and 77 by the rotation of the first and second rotary cams 60 and 70. And mounted to each of the first and second levers 65 and 75 so as to correspond selectively to the blocking grooves 61 and 71 of the first and second rotary cams 60 and 70. Blocking protrusions 67 and 77 are formed, respectively.

Further, first and second connectors 80 and 90 are provided on one side of the timer 50 so as to be adjacent to the first and second levers 65 and 75, respectively. Movable terminals 81 and 91 are mounted on one side of the first and second connectors 80 and 90 so as to be elastically operated by rotation of the first and second levers 65 and 75, respectively, and the movable terminal. The fixed terminals 82 and 92, which are selectively connected by the operation of the movable terminals 81 and 91, are mounted at positions adjacent to the 81 and 91, respectively.

Meanwhile, one end of the movable terminals 81 and 91 is connected by the wiring of the direct terminals 30A and 30B and the wires 85A and 95A, and one end of the fixed terminals 82 and 92 is indirect. The terminals 31A and 31B are connected by wirings of the wires 85B and 95B.

Referring to the operation of the plug socket according to the present invention as described above are as follows.

First, as shown in Figs. 1 and 2, when the terminals 26A, 26B of the plug 25 are inserted through the direct through holes 20A, 20B of the plug socket 10, the terminals 26A, 26B.

The blocking protrusions 67 and 77 of the first and second levers 65 and 75 correspond to each other and are fitted into the blocking grooves 61 and 71.

In this state, since the movable terminals 81 and 91 of the first and second connectors 80 and 90 are kept at a predetermined distance from the fixed terminals 82 and 92, the wires 85A, 85B) The electrical circuits of 95A and 95B are cut off.

Then, when the user rotates the knob 51 of the timer 50 to set an arbitrary time, the first and second rotary cams 60 and 70 are rotated by the rotation of the rotary shaft 52, thereby blocking the groove. The blocking projections 67 and 77 of the first and second levers 65 and 75 are separated from the 61 and 71.

On the other hand, as shown in Figure 4, the rotation shaft 52 of the timer 50 is rotated for an arbitrary set time, at which time the first and second on the outer peripheral surface of the first and second rotary cams 60, 70 Since the blocking projections 67 and 77 of the two levers 65 and 75 are contacted and rotated, the first and second levers 65 and 75 are rotated about the shafts 66 and 76, respectively.
