Abstract

A structure of connecting an earth terminal of 110/220 volt outlets with a ground terminal is provided to solidly fix the earth terminal by pressurization when the ground terminal and the earth terminal are inserted into a boss, thereby preventing connection badness. A hole(11) is punched in a ground terminal so that the ground terminal(10) and an earth terminal(20) are engaged. A cutting part generated in the outside of the hole is protruded upward. A hole(21) is punched in the earth terminal. An upper side of an upward exposed cutting unit is pressurized when the hole of the earth terminal is inserted into the protruded cutting unit of the ground terminal. A holding unit(13) is formed while the cutting unit is widened toward the outside. The ground terminal and the earth terminal are closely combined.

Description

110/220볼트 콘센트의 어스단자를 접지단자와의 접속구조{Connect structure of a concentic plug}Connect structure of a concentic plug to earth terminal of 110/220 volt outlet

본 발명은 110/220볼트 콘센트의 어스단자를 접지단자와 접속하게 되는 접속구조에 관한 것으로, 특히 접지단자와 어스단자가 법규상으로 임의적인 분리가 불가능하게 고정되어져야 한다는 규정에 의하여 개발된 것이다.The present invention relates to a connection structure in which the earth terminal of a 110/220 volt outlet is connected to a ground terminal, and in particular, the ground terminal and the earth terminal have been developed by a regulation that can not be arbitrarily fixed by law. .

현재 이러한 법규에 충족시키기 위한 방식으로는 도5에 도시된 바와 같이 접지단자(100)와 어스단자(200)의 어느 일측으로 안착공(110)을 형성하고, 상기 안착공(110)에 끼워지도록 공간부(210)가 구비된 걸림턱(220)을 구비토록 함으로서 걸림턱(220)이 안착공(110)에 결합된 상태에서 일방향으로 일정각도를 회전시키면 걸림턱(220)에 의하여 접지단자와 어스단자가 임의적인 분리가 불가능하게 조립되어지는 것이 제안되고 있는 것이다.As a way to meet the current law, as shown in Figure 5 to form a seating hole 110 to either side of the ground terminal 100 and the earth terminal 200, so as to fit in the seating hole (110) By having the locking jaw 220 with the space 210 provided therein, when the locking jaw 220 is rotated by one direction in a state in which the locking jaw 220 is coupled to the seating hole 110, the grounding terminal is connected to the ground terminal by the locking jaw 220. It is proposed that the earth terminals are assembled without arbitrary separation.

그러나 이러한 것은 안착공(110)에 끼워져 걸림턱(220)에 걸려 임의적인 이탈이 방지되어지는 장점이 있으나 이러한 것이 끼워지고 회전되어지기 위하여 형성되는 유격에 의하여 또는 금속의 특성상 온도의 변화에 따른 수축팽창으로 접속불량이 발생된다는 단점과 특히 안착공(110)과 결합되어지는 공간부(210)를 구비한 걸림턱(220)을 형성하기 위한 가공이 펀칭과 절곡과 걸림턱의 구현을 위한 또 다른 형태의 절곡에 의한 공정의 추가로 제조상의 문제점이 있는 것이었다.However, this has an advantage that the arbitrary separation is prevented by being caught in the seating hole 110 to be caught by the locking jaw 220, but it is contracted due to the change in temperature due to the clearance formed to be inserted and rotated or the characteristics of the metal. Another problem for the implementation of the punching and bending and the locking jaw is a process for forming the locking jaw 220 with the space portion 210 that is coupled with the seating hole 110 and the disadvantage that connection failure occurs due to expansion There was a manufacturing problem with the addition of the process by bending the form.

따라서 본 발명에서는 접지단자에 보스를 형성토록 한 후 어스단자에는 상기 보스에 기워지게 구멍을 천공한 후 돌출된 보스를 가압토록 함으로서 임의적인 이탈을 방지하면서 완전한 결합을 가능토록 함은 물론 제조의 용이성과 구조의 간단화를 꾀하게 된 것이다.Therefore, in the present invention, the boss is formed on the ground terminal, and then the hole is drilled in the ground terminal to allow the boss to pressurize the protruding boss, thereby preventing the complete detachment while allowing complete coupling, as well as ease of manufacture. And the structure is simplified.

이를 위하여 접지단자와 어스단자가 맞물리도록 하기 위하여 서로 밀착되어지는 부분에 접지단자에는 홀을 천공할 경우에 발생되는 절개부를 상측으로 돌출되게 보스를 형성하고, 상기 보스의 외측을 감싸면서 끼워지게 어스단자에는 구멍을 천공하는 것이다.To this end, a boss is formed to protrude upwards in the cutout portion generated when a hole is drilled in the ground terminal to a portion in close contact with each other so that the ground terminal and the earth terminal are engaged with each other. A hole is drilled in the terminal.

그후 보스에 구멍이 끼워진 상태에서 노출된 보스의 상측을 가압하면 보스가 외측으로 벌어지게 되면서 접지단자와 어스단자는 견고한 결합이 이루어지게 되는 것이다.Then press the upper side of the exposed boss in the state that the hole is inserted into the boss is the boss is opened to the outside and the ground terminal and the earth terminal is a solid coupling is made.

따라서 접지단자와 어스단자가 보스에 끼워진 상태에서 가압에 의하여 어스단자를 견고하게 고정하게 됨으로 접지단자와 어스단자의 유격이 없어 접촉불량이 없고 또한 결합된 상태에서 어떠한 외력에 의하여도 분리가 되지 않게 되면 제작과 정이 간단함으로 제작비용도 저렴하게 제공이 가능하게 되는 것이다.Therefore, the earth terminal and the earth terminal are firmly fixed to the earth terminal by pressurization while the earth terminal is fitted to the boss, so there is no clearance between the earth terminal and the earth terminal, so that there is no contact defect and the separation is not separated by any external force in the combined state. If the production process is simple, the production cost can be provided at a low cost.

이하 일 실시예에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the following examples.

도1에 도시된 바와 같이 본 발명의 구성은 110/220볼트 콘센트의 어스단자를 접지단자와의 접속토록 하는 통상의 구조에 있어서, 접지단자(10)와 어스단자(20)가 맞물리도록 하기 위하여 서로 밀착되어지는 부분에 접지단자(10)에는 펀칭에 의하여 홀(11)을 천공할 경우에 홀(11)의 외측으로 발생되는 절개부(12)를 상측으로 돌출되게 형성하고, 상기 절개부(12)의 외측을 감싸면서 끼워지게 어스단자(20)에는 구멍(21)을 천공하는 것이다.As shown in FIG. 1, the configuration of the present invention is to allow the ground terminal 10 and the earth terminal 20 to be engaged in a conventional structure in which the earth terminal of the 110/220 volt outlet is connected to the ground terminal. In the case where the hole 11 is drilled by the punching in the portion that is in close contact with each other, the cutout portion 12 which is generated to the outside of the hole 11 is formed to protrude upward, and the cutout portion ( A hole 21 is drilled in the earth terminal 20 to be fitted while wrapping the outer side of the 12).

이때 절개부(12)는 좌우 양측으로 형성토록 하는 것이다.At this time, the incision 12 is to be formed on both sides.

그후 접지단자(10)의 돌출된 절개부(12)에 어스단지(20)의 천공된 구멍(21)이 끼워진 상태에서 어스단자(20)의 구멍(21) 상측으로 노출된 절개부(12)의 상측을 가압하면 절개부(12)가 외측으로 벌어지게 되면서 걸림부(13)를 형성하여 접지단자(10)와 어스단자(20)는 틈이 없이 긴밀한 밀착이 이루어지게 되는 것이고 걸림부(13)에 의하여 접지단자(10)와 어스단자(20)는 임의적인 이탈이 방지되어지는 것이다.Thereafter, the cutout portion 12 exposed to the upper portion of the hole 21 of the earth terminal 20 while the drilled hole 21 of the earth terminal 20 is fitted into the protruding cutout portion 12 of the ground terminal 10. Pressing the upper side of the cutout 12 is opened to the outside to form a catching portion 13, the ground terminal 10 and the earth terminal 20 is in close contact without a gap is made and the catching portion 13 The ground terminal 10 and the earth terminal 20 by) is to be prevented from being separated randomly.

또한 도2에 도시된 바와 같이 이러한 절개부(12)를 홀이 원형이기 때문에 사방으로 형성할 경우에는 접지단자(10)와 어스단자(20)의 밀착력이 더욱 우수함은 물론 결합력을 증진토록 하는 것이고, 이때 본 발명에서는 원형의 홀의 형태로 설명하고 있으나 이를 사작형이나 다각형으로 형성할 경우에도 동일한 효과를 발생시 키는 것이다.In addition, as shown in FIG. 2, when the cutout 12 is formed in all directions because the hole is circular, the adhesion between the ground terminal 10 and the earth terminal 20 is more excellent, as well as to enhance the bonding force. In this case, the present invention has been described in the form of a circular hole, but the same effect will occur even when it is formed in a man-made or polygon.

또한 도3에 도시된 바와 같이 접지단자에는 프레스의 드로잉공법에 의하여 접지단자(10)에 상측으로 돌출되게 보스(14)의 형태로 돌출토록 하여 어스단자의 구멍과 결합한 후 상측을 가압함으로서 접지단자(10)와 어스단자(20)의 임의적인 이탈을 방지하게 되는 것이다.In addition, as shown in Fig. 3, the grounding terminal is projected upwardly to the grounding terminal 10 by the drawing method of the press so as to protrude in the form of the boss 14 to engage with the hole of the earth terminal and then press the upper side by pressing the grounding terminal. It is to prevent the random departure of the (10) and the earth terminal (20).

따라서 접지단자와 어스단자가 가압에 의한 물림이 발생됨으로 제조의 용이성과 우수한 밀착력을 제공하게 되는 것이다.Therefore, the grounding terminal and the earth terminal are provided with a bite due to the pressurization to provide ease of manufacture and excellent adhesion.
