As shown in FIGS. 14 to 18 , in a state in which a plug is mounted on the plug mounting portion 11 and the head of the plug is in contact with the cover 30 , the elevating member 400 may be in a maximum raised state.

The L1 pin of the plug may be in contact with the first contact terminal 61 inside the first partitioned space 15a.

Also, the L2 pin of the plug may be in contact with the second contact terminal 62 inside the second partitioned space 15b.

Also, the lower end of the L2 pin of the plug may be in contact with the inclined surface 522a of the second rotating member 520 .

Also, the first extension part 512 of the first rotating member 510 may be in a state in which movement inward for energization is restricted by the first restraining bar 421 . That is, the first extension part 512 may contact and be supported by the protruding contact part 423 of the first restraining bar 421 so that the inward movement is restricted.

In addition, the first extension part 522 of the second rotating member 520 may be in a state in which movement inward for energization is restricted by the second restraining bar 422 . That is, the second extension part 522 may contact and be supported by the protruding contact part 423 of the second restraining bar 422 so that the inward movement is restricted.

In this case, the contact portion 423 may form a vertical portion 423a and an inclined portion 423b formed on an upper portion of the vertical portion 423a. In addition, the first extension part 512 of the first rotation member 510 and the first extension part 522 of the second rotation member 520 contact the vertical part 423a of the contact part 423 and may be supported.

Therefore, even if rotational force is generated in the direction for energizing the first rotational member 510 and the second rotational member 520, by the action of the inclined portion 423b of the contact portion 423 and the

rotational members

510 and 520. A problem in which the restraint of the

rotating members

510 and 520 is forcibly released when the elevating member 400 is lowered can be prevented.

At this time, as shown in FIG. 17 , the first rotating member 510 may be in an initial state rotated so that the first power terminal 51 and the first energizing terminal 71 are maximally spaced apart from each other.

Also, the second rotating member 520 may be in an initial state in which the second power terminal 52 and the second power supply terminal 71 are rotated to the maximum distance from each other.

In addition, the first rotating member 510 and the second rotating member 520 are disposed symmetrically to each other along the longitudinal direction of the case 10 and are configured to rotate in opposite directions for current, so that the first The second extension part 513 of the rotation member 510 and the second extension part 523 of the second rotation member 520 may be maximally adjacent to each other.

And, the original elastic member 530 is applied as a tension spring connecting the second extension part 513 of the first rotation member 510 and the second extension part 523 of the second rotation member 520 , It may be in a state in which the first rotating member 510 and the second rotating member 520 are pulled in a direction opposite to the rotational direction for energization.

Meanwhile, as shown in FIGS. 19 and 20 , when the elevating member 400 is pressed and pressed by the head of the plug, the elevating member 400 may descend together with the head of the plug.

Also, the elastic member 90 disposed between the elevating member 400 and the block case 200 may be applied as a compression spring and compressed.

Also, the first rotating member 510 may be rotated in a direction for conducting electricity by the action of the L1 pin of the plug and the inclined surface 512a of the first extension part 512 . That is, the first extension part 512 may be moved to the inside where the first restraining bar 421 is located.

rotating members

A predetermined separation space for elastic deformation of the first restraining bar 421 may be formed between the first restraining bar 421 and the inner wall of the first compartment space 15a. At this time, the separation space is formed between the first power terminal 51 and the first power supply terminal 51 so that electricity is not forcibly conducted in a state in which the first restraining bar 421 does not release the restraint of the first rotating member 510. Before the conducting terminals 71 come into contact with each other, the first restraining bar 421 and the inner wall of the first compartment space 15a may be formed in a contact width.

In addition, a predetermined separation space for elastic deformation of the second restraining bar 422 may be formed between the second restraining bar 422 and the inner wall of the second compartment space 15b. At this time, the separation space is formed between the second power terminal 52 and the second power supply terminal 52 so that power is not forcibly conducted in a state in which the second restraining bar 422 does not release the restraint of the second rotating member 520. Before the conducting terminals 72 come into contact, the second restraining bar 422 and the inner wall of the second compartment space 15b may be formed in a contact width.

As the plug and the elevating member 400 descend, the restraining bars 421 and 422 are elastically deformed, and the vertical portion 423a of the contact portion 423 may also be moved downward.

rotating members

510 and 520, and the inclined portion 423a of the contact portion 423 It may contact the first extension part of the

rotating members

bars

421 and 422 and the first extension part is energized by the inclination part 423b of the contact part 423. movable space can be secured. That is, as the restraining bars 421 and 422 are lowered, the first extension part is relatively moved upward along the contact portion 423, and the restraint by the restraining bar 423 is gradually released, so that the rotating member ( 510 and 520) may be rotated in a direction for energization.

And, when the elevating member 400 descends to the maximum, the rotating

members

510 and 520 may be completely separated from the contact portion 423 of the restraining bar 420 and rotated to the maximum in the direction for energization. there is. That is, the first rotating member 510 and the second rotating member 520 may be maximally rotated in the direction for energization.

In addition, the rotation of the first rotating member 510 causes the first power terminal 51 to contact the first conducting terminal 71 so that the first contact terminal 61 can be energized.

In addition, the rotation of the second rotating member 520 causes the second power supply terminal 52 and the second conducting terminal 72 to come into contact so that the second contact terminal 62 can be energized.

As the first contact terminal 61 and the second contact terminal 62 become energized, power may be supplied to the mounted plug.

When the plug is removed, the elevating member 400 may be elevated by the elastic force of the elastic member 90 .

And, the first rotating member 510 and the second rotating member 520 may be rotated to their initial positions by the elastic force of the original elastic member 530 .

In addition, as the elevating member 400 rises, the rotating

members

510 and 520 may be rotated in the direction for energization by the restricting bar 420 .

That is, the elevating member 400 contacts the

rotating members

510 and 520 in an initial state in an elevated state and blocks the rotational space for energization to constrain rotation for energizing the

rotating members

510 and 520. .

In addition, the elevating member 400 can be regarded as creating or opening a rotational space for energization by being spaced apart from the

rotational members

510 and 520 in an initial state when descending.

That is, it can be seen that the rotation for energizing the rotating member is constrained by the contact portion 423 protruding outward toward the rotating

members

510 and 520 rather than the restraining bars 421 and 422 .
