Description
본 발명은 안전 콘센트에 관한 것으로, 보다 상세하게는 플러그를 삽입한 경우에만 통전되며, 전기의 극성별로 분리된 배수관에 의해 물의 유입에도 감전과 합선을 예방하는 기능을 가지는 안전 콘센트에 관한 것이다.The present invention relates to a safety outlet, and more particularly, to a safety outlet that is energized only when a plug is inserted and has a function of preventing electric shock and short-circuit even when water flows in through a drain pipe separated by electrical polarity.
일반적으로 가정, 사무실 등의 실내공간이나 외부 작업 현장 등의 외부공간에서 전기를 이용하는 경우 벽면 등에 설치되거나 멀티탭에 마련된 콘센트에 플러그를 꽂아서 전기를 공급받는다.In general, when electricity is used in an indoor space such as a home or office or an external space such as an external work site, electricity is supplied by plugging a plug into an outlet installed on a wall or the like or provided in a multi-tap.
콘센트는 건물의 내, 외부 벽면이나 선박, 기차, 비행기 등 전기가 사용되는 모든 곳에서 전기 플러그를 꽂아 사용하는 일반적인 콘센트와, 멀티탭 등에 마련되어 전기 플러그를 꽂아 사용할 수 있는 콘센트를 포함한다.The outlet includes a general outlet used by inserting an electric plug in any place where electricity is used, such as inside or outside walls of buildings, ships, trains, airplanes, etc.
종래의 콘센트는 플러그의 핀 삽입구가 항상 개방된 상태를 가지고 외부로 노출되어 사용되는 경우가 대부분이기에 외부로부터 각종 이물질이 쉽게 내부로 침투될 수 있다. 즉, 물기나 습기가 많은 장소에서 콘센트를 사용하는 경우 물기나 습기가 콘센트 내부로 침투하여 합선 또는 감전 등의 안전사고가 발생되는 문제점이 있다. 또한, 콘센트는 플러그의 핀이 삽입되는 홀에 금속 재질의 물건이 삽입되어 안전사고가 발생되는 경우도 빈번하였다.In most cases, the conventional outlet is exposed to the outside while the pin insertion hole of the plug is always open, so that various foreign substances from the outside can easily penetrate into the inside. That is, when the outlet is used in a wet or humid place, there is a problem in that safety accidents such as short circuits or electric shocks occur because moisture or moisture penetrates into the outlet. In addition, safety accidents frequently occur when an object made of metal is inserted into a hole into which a pin of a plug is inserted.
최근에는 종래의 콘센트의 문제점을 개선하기 위해 플러그의 장착 시 핀 삽입구가 개방되거나, 방수 기능 등을 가지는 안전 강화형 콘센트가 개발되고 있다.Recently, in order to improve the problems of the conventional outlet, a pin insertion port is opened when a plug is installed, or a safety-reinforced outlet having a waterproof function has been developed.

그리고, 선행문헌의 콘센트의 경우 금속 이물질의 삽입 등에 의해서 핀 삽입구가 개방되거나, 핀 삽입구를 차폐하는 차폐부재의 오작동에 의해서 핀 삽입구가 개방된 상태에서 핀 삽입구 내부로 물이 유입되면, 유입된 물이 효과적으로 배출되지 못하고 합선 사고가 발생할 수 있는 문제가 있다.And, in the case of the outlet of the prior literature, if the pin insertion hole is opened by the insertion of a metal foreign substance or the like, or if water flows into the pin insertion hole in a state where the pin insertion hole is opened due to a malfunction of the shielding member that shields the pin insertion hole, the inflow water There is a problem that this is not effectively discharged and a short circuit accident may occur.
따라서, 금속 이물질의 삽입에 의한 감전 사고를 방지할 수 있으며, 핀 삽입구를 통해 내부로 액체가 유입되는 경우에도 합선 등의 사고를 효과적으로 방지할 수 있는 안전성이 보다 강화된 새로운 개념의 안전 콘센트가 요구된다.Therefore, it is possible to prevent electric shock accidents caused by the insertion of metal foreign substances, and a safety outlet of a new concept with more enhanced safety that can effectively prevent accidents such as short circuit even when liquid flows into the inside through the pin insertion hole is required. do.

플러그와 승강부재(400)가 하강됨에 따라, 상기 구속바(421,422)가 탄성 변형되면서 상기 접촉부(423)의 수직부(423a)도 하강으로 이동될 수 있다.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.
상기 구속바(421,422)의 하강에 의해서 상기 접촉부(423)의 수직부(423a)가 상기 회전 부재(510,520)의 제1 연장부의 하방으로 이탈되고, 상기 접촉부(423)의 경사부(423a)가 상기 회전 부재(510,520)의 제1 연장부에 접촉될 수 있다.As the restraining bars 421 and 422 descend, the vertical portion 423a of the contact portion 423 disengages downward from the first extension portion of the 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 510 and 520 .
그리고, 상기 구속바(421,422)가 지속적으로 하강됨에 따라, 상기 접촉부(423)의 경사부(423b)에 의해서 상기 구속바(421,422)와 상기 제1 연장부 사이에 제1 연장부가 통전을 위한 방향으로 이동 가능한 공간이 확보될 수 있다. 즉, 상기 구속바(421,422)가 하강됨에 따라 상기 제1 연장부가 상기 접촉부(423)를 따라 상대적으로 상방으로 상대 이동되고, 상기 구속바(423)에 의한 구속이 점차적으로 해제되어 상기 회전 부재(510,520)가 통전을 위한 방향으로 회전될 수 있다.Further, as the restraining bars 421 and 422 continuously descend, the direction of the first extension between the restraining 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.

That is, the first rotating member 510 and the second rotating member 520 may be maximally rotated in the direction for energization.
그리고, 상기 제1 회전 부재(510)의 회전에 의해서 상기 제1 전원 단자(51)와 제1 통전 단자(71)가 접촉되어 제1 접촉 단자(61)가 통전된 상태가 될 수 있다.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.
그리고, 상기 제2 회전 부재(520)의 회전에 의해서 상기 제2 전원 단자(52)와 제2 통전 단자(72)가 접촉되어 제2 접촉 단자(62)가 통전된 상태가 될 수 있다.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.
상기 제1 접촉 단자(61)와 제2 접촉 단자(62)가 통전된 상태가 됨에 따라 장착된 플러그에 전원이 공급될 수 있다.As the first contact terminal 61 and the second contact terminal 62 become energized, power may be supplied to the mounted plug.
플러그를 탈거하는 경우에는, 상기 승강 부재(400)가 상기 탄성 부재(90)의 탄성력에 의해서 상승될 수 있다.When the plug is removed, the elevating member 400 may be elevated by the elastic force of the elastic member 90 .
그리고, 상기 제1 회전 부재(510)와 제2 회전 부재(520)는 상기 원복 탄성 부재(530)의 탄성력에 의해서 초기 위치로 회전될 수 있다.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 .
