The switch member 330 is inserted into the internal space of the extension member 320 and may include a lifting pillar portion 331 that supports the extension member 320 from below.

The lifting pillar part 331 may be formed in a circular pillar shape so that it can be lifted and lowered along the inside of the pillar part 321.

A pillar protrusion 331a inserted into the through hole 222 may be formed on the upper surface of the lifting pillar part 331.

The pillar protrusion 331a may be formed in the shape of a circular pillar having a diameter smaller than the diameter of the lifting pillar part 331. That is, the circumferential surface of the pillar protrusion 331a may be stepped from the circumferential surface of the lifting pillar portion 331.

An elastic member insertion groove 331b may be formed in the lifting pillar portion 331 into which a support elastic member 352, which will be described later, is inserted.

The elastic member insertion groove 331b may be formed by recessing the center of the lower surface of the lifting pillar portion 331 upward. That is, a space opening downward may be formed inside the lifting pillar portion 331.

A lower clutch part 335 may be formed at the lower part of the lifting pillar part 331.

The lower clutch unit 335 may function in conjunction with the upper clutch unit 325 for one-touch operation.

In detail, the lower clutch part 335 may be formed to protrude outward from the peripheral surface of the lifting pillar part 331 so as to engage with the upper clutch part 325.

The restraining protrusion 341 may be formed to have a width corresponding to the slit portion 322 and the protrusion moving portion 336 so that it can move relative to the slit portion 322 and the protrusion moving portion 336.

On the lower surface of the restraining protrusion 341, a protrusion inclined portion 341a may be formed that is inclined upward in the normal rotation direction of the opening and closing member 310.

Meanwhile, the elastic member 350 may include a spaced elastic member 351 for lifting and returning the extension member 320 from the switch member 330.

For example, the spaced elastic member 351 may be applied as a compression spring.

Referring to FIG. 12 , the spacing elastic member 351 may be disposed between the upper surface of the lifting pillar portion 331 and the opening and closing member 310. Accordingly, the extension member 320 coupled with the opening and closing member 310 can be elastically supported from the switch member 330 by the spaced elastic member 351.

Accordingly, the extension member 320 may be relatively lowered to approach the switch member 330 when the lifting case 200 is pressed downward. Also, when the extension member 320 is released from the lifting case 200, it can be relatively lifted away from the switch member 330 by the elastic force of the spacing elastic member 351.

As the extension member 320 is relatively lifted and lowered from the switch member 330, the upper clutch unit 325 and the lower clutch unit 335 repeat engagement and disengagement, and an interlocking operation for a one-touch function may be performed.

Meanwhile, the elastic member 350 may include a support elastic member 352 for lifting and restoring the switch module 300.

Meanwhile, the configuration of the upper clutch part 325, the lower clutch part 335, and the restraining protrusion 341 is not limited to the above-described embodiment, and is controlled by the elevation of the extension member 320 and the switch member 330. It can be applied in a variety of structures that can be linked to provide one-touch functionality.

For example, the directions of the inclined surfaces formed on the upper clutch part 325 and the lower clutch part 335 may be formed in opposite directions, and in this case, the lower clutch part 335 is connected to the switch member 330, which will be described later. ), the direction of rotation to provide the one-touch function may be reversed.

Hereinafter, the overall operation of the one-touch type outlet according to an embodiment of the present invention will be described in detail with reference to the drawings.

In the initial state in which the plug is not installed, the opening and closing member 310, the extension member 320, and the switch member 330 may be in a maximum raised state.

When the opening and closing member 310 is raised to the maximum, the lifting case 200 accommodating the opening and closing member 310 may be supported by the opening and closing member 310 and raised to the maximum.

At this time, the opening and closing member 310 may be in its initial state rotated to its maximum in the reverse direction so as to shield the pinhole 224.

At this time, as in state A1 of FIG. 15, the slit portion 322 of the extension member 320 may be rotated to one side to prevent the restraining protrusion 341 of the restraining member 340 from being inserted. That is, the first upper inclined portion 325a may be positioned vertically above the restraining protrusion 341.

Therefore, even if the lifting case 200 is pressed downward, the extending member 320 interferes with the restraining protrusion 341 and cannot be lowered, so the lowering of the lifting case 200 may be restricted. .

Additionally, the upper clutch unit 325 may be separated from the restraining member 340 and positioned above the restraining member 340.

In addition, the lower clutch unit 335 may be located on the inner upper part of the restraining member 340 and its rotation may be restricted by the restraining protrusion 341. In other words, the restraining protrusion 341 may be located on the protrusion moving part 336 so that the rotation of the switch member 330 is restricted.

Additionally, the power terminal 20 and the energizing terminal 40 may be spaced apart so that power is not supplied to the contact terminal 30 .

Meanwhile, as shown in FIG. 13, when the pin of the plug 2 is normally inserted through the lifting case 200, the opening and closing member 310 is opened by contact between the pin of the plug 2 and the rotation inducing inclined surface 312b. It may be rotated in the forward direction.

That is, as in state A2 of FIG. 15 , the opening and closing member 310 may be rotated so that the opening and closing hole 312a is positioned vertically above the pinhole 224 .

At this time, the extension member 320 may be rotated together with the rotation of the opening and closing member 310.

Additionally, the slit portion 322 of the extension member 320 may be positioned vertically above the restraining protrusion 341.

Accordingly, the restraining protrusion 341 is inserted into the slit portion 322 and becomes movable. That is, the extension member 320 can be lowered and the lowering restraint of the lifting case 200 can be released.

Meanwhile, as shown in FIG. 14 , when the pin of the plug 2 is inserted through the steel case 200 and the plug 2 is pressed downward, the lifting case 200 may be lowered.

As the lifting case 200 is lowered, the pin of the plug 2 may be inserted into the partition space 103 through the pin through hole 142 of the cover housing 140.

And, the pin of the plug 2 may be in contact with the contact terminal 30.

Additionally, the power supply unit 50 may rotate through contact with the pin of the plug 2 to bring the power terminal 20 and the power supply terminal 40 into contact. Accordingly, power can be supplied to the contact terminal 30 to supply power to the plug 2.

And, the lifting case 200 can be fixed in a lowered state by the operation processes A3, A4, and A5 of the switch module 300, as shown in FIG. 15. That is, the raising of the lifting case 200 may be restricted.

In detail, when the opening and closing member 310 is rotated forward, the slit portion 322 and the protrusion moving portion 336 may be aligned vertically.

At this time, when the user presses the plug 2 downward, the extension member 320 is relatively lowered to approach the switch member 330, and the spaced elastic unit 351 may be in a compressed state.

As the extension member 320 is lowered, the first upper inclined portion 325a may be in contact with the first lower inclined portion 335a. Additionally, the second upper inclined portion 325c may be in contact with the second lower inclined portion 335c.

When the user continuously presses the plug 2 downward, the lifting case 200 is continuously lowered, and the extension member 320 and the switch member 330 can be lowered together while being engaged with each other.

When the lifting case 200 is lowered to the maximum as in the A3 state, the lower clutch portion 335 of the switch member 330 passes through the restraining protrusion 341 and reaches the lower portion of the restraining member 340. It can be located in .

Additionally, the restraining protrusion 341 may be completely inserted into the slit portion 322 of the extension member 320.

As in the A4 state, when the lower clutch unit 335 passes the restraining protrusion 341, the switch member 330 acts on the inclined surfaces formed on the lower clutch unit 335 and the upper clutch unit 325. It can be rotated in the forward direction by .

At this time, the restraining protrusion 341 may be positioned above the second lower inclined portion 335c by normal rotation of the switch member 330. Also, the forward rotation of the switch member 330 may be limited by engagement of the upper clutch unit 325 and the lower clutch unit 335.

Thereafter, when the user completes the insertion and installation of the plug 2 and the plug 2 stops being pressed, the extension member 320 is moved to the upper clutch by the action of the spaced elastic member 351 as in the A5 state. The unit 325 may be slightly raised to separate from the lower clutch unit 335.

Additionally, the switch member 330 may be further rotated forward by the action of the inclined surface of the second lower inclined portion 335c and the protruding inclined portion 341a.

At this time, the restraining protrusion 341 may move along the inclined surface of the second lower inclined portion 335c and contact the lower vertical portion 335b.

Also, as the restraining protrusion 341 contacts the lower vertical portion 335b, the normal rotation of the switch member 330 may be stopped.

At this time, the restraining protrusion 341 can be seen as being inserted into the lower groove formed by the lower vertical portion 335b and the second lower inclined portion 335c.

As the restraining protrusion 341 is located in the lower groove, the upward movement of the switch member 330 may be restricted. Accordingly, the extension member 320 and the opening/closing member 310 supported by the switch member 330 can be fixed in a lowered state. Accordingly, the lifting case 200 can also be fixed in a lowered state.

That is, the height of the safety switch unit is fixed in a shortened state, so that the lifting case 200 can maintain the lowered position.

Meanwhile, when the user presses the plug 2 downward again to remove the plug 2, the upward restraint of the switch member 330 may be released by the operation of the switch module 300.

And, as the upward restraint of the switch member 330 is released, the opening and closing member 310 and the extension member 320 can be raised.

And, as the opening and closing member 310 rises, the lifting case 200 may rise.

And, as the lifting case 200 is raised, the plug 2 may be raised and removed, and the pin may be separated from the contact terminal 30.

And, as the pin of the plug 2 is separated from the partition space 103, the electricity supply unit 50 can be returned to its initial position. In addition, the contact between the power terminal 20 and the energizing terminal 40 may be released and the power supplied to the contact terminal 30 may be cut off.

Referring to FIG. 16, when the lifting case 200 is pressed again by the plug 2, the switch member 330 may be lowered as in the B1 state.

And, as the switch member 330 descends, the restraining protrusion 341 may be separated from the lower groove portion.

And, as the restraining protrusion 341 deviates from the lower groove, the switch member 330 can be rotated forward by the action of the inclined surface of the restraining protrusion 341 and the inclined surface of the upper clutch unit 325. there is. At this time, with the restraining protrusion 341 in contact with the second lower inclined portion 335c, the lower clutch portion 335 is engaged with the upper clutch portion 325, thereby causing the switch member 330 to move. Forward rotation may be stopped.

Thereafter, when the user stops pressing the plug 2 downward, the extension member 320 may be slightly raised from the switch member 330 by the action of the spacing elastic member 351.

Additionally, the engagement between the lower clutch unit 335 and the upper clutch unit 325 may be released by slightly raising the extension member 320. Accordingly, the switch member 330 can be further rotated forward by the action of the inclined surfaces of the protruding inclined portion 341a and the second lower inclined portion 335c.

Thereafter, as in the B2 state, the restraining protrusion 341 may be positioned in alignment with the protrusion moving portion 336 of the switch member 330. Accordingly, the upward restraint of the switch member 330 can be released.

Thereafter, as in the B3 state, the upward restraint of the switch member 330 is released and the switch member 330 can be raised by the support elastic member 352.

And, as the switch member 330 is raised, the lifting case 200 may be raised and returned to its initial position.

That is, the restriction on shortening the height of the safety switch unit is lifted and the height is extended, and the lifting case 200 can be raised and returned to its initial position by extending the height of the safety switch unit.

And, when the pin of the plug 2 is completely separated from the lifting case 200, the opening and closing member 310 can be reversely rotated and returned to its initial position. And, as the opening and closing member 310 returns to its initial position, the pinhole 224 may be shielded and the lowering of the lifting case 200 may be restricted.
