제6도는 종래 압력스위치의 평면도.6 is a plan view of a conventional pressure switch.

본 고안은 상부 고정지지대를 합성수지제로 일체로 형성하고, 하나의 개폐단자편을 설치하되, 개폐단자편 타측에 공통단자편을 설치 구성하여 압력에 따른 개, 폐작동은 물론 타회로를 제어할 수 있도록 하는 압력스위치에 관한 것이다.The present invention is to form the upper fixed support integrally made of synthetic resin, and to install one open and close terminal piece, by installing a common terminal piece on the other side of the open and close terminal piece can control the opening and closing operation according to the pressure as well as other circuits. It relates to a pressure switch to make.

종래 압력스위치는 제6도에 도시한 바와같이, 스프링을 지지해주는 고정지지대(21)를 금속제로 설치형성하고, 합성수지제로된 상부 고정지지대(22)상방 양측에 개폐단자편(23)(24)을 설치하며, 이단자편(23)(24)의 접점 하방에 가동단자편(25)을 스프링에 의해 탄력설치 하고있기 때문에, 압력에 의한 ON/OFF 개폐는 용이하게되나, 양측의 개폐단자편(23)(24)의 압력의 불평형에 의해 OFF될 경우 전원이 완전 OFF되므로, 예로서 시그날 램프를 점등 한다든지, 경보음을 발생시킨다든지 하는 다른 회로를 제어할 수 없도록 되어 있다. 즉, 압력의 불평형에 의해 압력스위치가 OFF될 경우 조작자가 압력스위치의 동작상태 유무를 확인하기 위한 가시 및 가청경보회로에 대한 회로 제어를 할 수 없게 되어 있다. 그리고, 개폐단자편 각각의 하방에 접점을 가지는 가동단자편이 설치 형성되어 있으므로, 이들의 단자편의 접점 가격이 비싸 압력스위치 전체의 제조단가가 상승되는 문제점이 지적되고 있으며, 공지한 바와같이, 스프링을 지지해 주는 고정지지대(21)와 가동단자편(25)의 개폐에 따라 발생되는 스파크 현상으로 인하여 절연이 파괴되어 누전의 위험이 가중되고 있는 설정이다. 이는 고정지지대(21)와 가동단자편(25)과의 거리가 매우 짧기 때문에 일어나는 현상으로써 좁은 공간내에서 별도의 고정지지대를 설치할 수 밖에 없는 경우에는 항시 상기와 같은 누전의 위험이 뒤따르게 된다.As shown in FIG. 6, the conventional pressure switch is formed of a metal fixing supporter 21 supporting the spring, and the opening and closing terminal pieces 23 and 24 on both sides of the upper fixing support 22 made of synthetic resin. Since the movable terminal piece 25 is elastically installed under the contact of the two terminal pieces 23 and 24 by a spring, ON / OFF opening and closing due to pressure is easy, but both opening and closing terminal pieces ( Since the power is completely turned OFF when the pressure is unbalanced by 23), other circuits such as turning on a signal lamp or generating an alarm sound, for example, cannot be controlled. That is, when the pressure switch is turned off due to the unbalance of pressure, the operator cannot control the circuits for the visible and audible alarm circuits to confirm the presence or absence of the operating state of the pressure switch. In addition, since the movable terminal pieces having contacts are formed below each of the opening and closing terminal pieces, there is a problem in that the price of the contacts of these terminal pieces is high and the manufacturing cost of the entire pressure switch is increased. Due to the spark phenomenon generated by the opening and closing of the fixed support 21 and the movable terminal piece 25 to support, the insulation is destroyed and the risk of electric leakage is increased. This phenomenon occurs because the distance between the fixed support 21 and the movable terminal piece 25 is very short, and when a separate fixed support must be installed in a narrow space, there is always a risk of electric leakage as described above.

본 고안은 상기와 같은 결함을 해소하기 위하여 하부본체 상방에 합성수지제로 상부고정 지지대를 설치하고, 상부고정 지지대 후측 중앙부에 압력조절나사를 나사조립하며, 상부 고정지지대 일측에 노말 크로스(NORMAL CLOSE)단자편을 설치한 다음, 그 하방에 공통단자편과 항상 접속되어 있는 판스프링으로된 가동편의 접점을 위치케 하고, 이 접점 하방에 노말 오픈(NORMAL OPEN)단자편을 설치 구성한 것으로써 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to install the upper fixing support made of synthetic resin above the lower body, to assemble the pressure adjustment screw in the rear center of the upper fixing support, to solve the above defects, the normal cross terminal on one side of the upper fixing support After installing the piece, place the contact point of the movable piece made of a leaf spring which is always connected to the common terminal piece below, and install the NORMAL OPEN terminal piece under this contact. It will be described in detail as follows.

즉, 하부본체(1)상방에 합성수지제로 상부 고정지지대(2)를 설치하고, 상부고정지지대(2)후측 중앙부에 공지한 압력조절나사(3)를 나사 조립하며, 상부 고정지지대(2)일측에 노말 크로스 단자편(4)을 설치한 다음, 이 하방에 공통단자편(5)과 항상 접속되어 있는 판스프링으로된 가동편(6)의 접점(6')을 위치케하고, 이접점(6') 하방에 노말 오픈 단자편(7)의 접점(7')을 위치시켜서된 것으로, 도면중 4'는 노말크로스단자편(4)의 접점, 6''는 가동편의 걸림구, 8은 작동간, 9는 노말크로스 단자편(4)에 접속되어 있는 전원측 도선, 10은 공통단자편(5)에 접속되어 있는 전원측 도선, 11은 노말오픈단자편(7)에 접속되어 있는 도선, 12는 뚜껑이다.That is, the upper fixing support (2) is installed on the lower body (1) made of synthetic resin, and the well-known pressure adjusting screw (3) is screwed on the rear center of the upper fixing support (2), the upper fixing support (2) one side After installing the normal cross terminal piece 4 at the bottom, place the contact point 6 'of the movable piece 6 made of a leaf spring which is always connected to the common terminal piece 5 below. 6 ') is positioned below the contact point 7' of the normal open terminal piece 7, wherein 4 'is the contact point of the normal cross terminal piece 4, 6' 'is the catch of the movable piece, and 8 is During operation, 9 is a power supply side lead connected to the normal cross terminal piece 4, 10 is a power supply lead connected to the common terminal piece 5, 11 is a lead connected to the normal open terminal piece 7, 12 Is the lid.

이와같이 구성된 본 고안의 작용효과는 다음과 같다. 압력 또는 진공회로에 있어서 정상동작을 하고 있을 경우에는 작동간(8)이 상승된 상태에서 공통단자편(5)과 항상 접속되어 있는 가동편(6)의 접점(6')이 노말 크로스 단자편(4)의 접점(4')과 맞닿게 되도록 되어 있어 전원이 도통되어 압력이나 진공을 유지하게 된다(제4도 참조). 그러나, 압력이 불평형 상태에 이르게 되면, 공지한 바와같이 작동간(8)이 하강하게 되어 판스프링으로 된 가동편(6)의 중심을 아래쪽으로 하강시키게 된다. 그러면, 가동편의 걸림구(6'')를 기점으로 하여, 가동편(6)의 접점(6')이 노말 크로스단자편(4)의 접점(4')으로 떨어지게 됨과 동시에, 노말오픈 단자편(7)의 접점(7')측에 닿게 된다. 이때, 공통단자편(5)을 가동편(6)과 항시 접속되어 있는 상태이므로, 공통단자(5)에 접속되어 있는 전원측도선(10)과 노말오픈단자편(7)에 접속되어 있는 도선(11)과는 폐회로를 구성시킬 수 있게 되어, 예로서 압력 불평형에 따라 전원이 오프되는 산태를 외부에서 확인 관측할 수 있는 램프 점등회로부를 제어할 수 있게 되는 것이다. 그러나. 종래에는 전원측 도선과 연결되어 있는 양측 단자편이 압력불평형에 따라 전원이 오프 될경우에는 전원측과는 완전차단 되므로 별도의 타회로를 제어할 수 없었다. 그리고, 본 고안에 있어서는 하부본체(1)상방에 별도의 스프링 고정지지대 없이 상부 고정지지대(2)를 합성수지제로 설치 형성하고 있으므로, 가동편(6)의 개, 폐작동시 발생되는 스파크에 의한 절연파괴의 위험을 배제할 수 있고, 노말크로스단자편(4)측에만 개, 폐접점을 형성시키고 있으므로, 종래와 같이 양측 단자편에 각각 개폐접점을 형성시킬 경우보다 접점에 대한 비용이 저렴하게 들어 결국 압력스위치 전체의 제조단가를 줄일 수 있게된다.Effects of the present invention configured as described above are as follows. When the normal operation is performed in the pressure or vacuum circuit, the contact 6 'of the movable piece 6, which is always connected to the common terminal piece 5, in the state where the operation 8 is raised, is the normal cross terminal piece. The contact 4 'of (4) is brought into contact with the power supply so as to maintain pressure or vacuum (see FIG. 4). However, when the pressure reaches an unbalanced state, as is known, the operating period 8 is lowered, which lowers the center of the movable piece 6 of the leaf spring downward. Then, the contact point 6 'of the movable piece 6 falls to the contact point 4' of the normal cross terminal piece 4, starting from the latching opening 6 '' of the movable piece, and the normal open terminal piece. It contacts the contact 7 'side of (7). At this time, since the common terminal piece 5 is always connected to the movable piece 6, the conducting wire connected to the power supply side lead 10 and the normal open terminal piece 7 connected to the common terminal 5 ( 11) can be configured as a closed circuit, for example, it is possible to control the lamp lighting circuit unit that can confirm the observation of the external state of the power off according to the pressure unbalance. But. Conventionally, when the power supply is turned off due to pressure imbalance, both terminal pieces connected to the power supply side wire are completely blocked from the power supply side, so that no other circuit can be controlled. In addition, in the present invention, since the upper fixing support 2 is formed of synthetic resin and formed without a separate spring fixing support above the lower body 1, insulation by sparks generated when opening and closing the movable piece 6 is performed. Since the risk of breakage can be eliminated, and the open and closed contacts are formed only on the normal cross terminal piece 4 side, the cost for the contact point is lower than that in the case where the open / close contact is formed on both terminal pieces as in the prior art. As a result, the manufacturing cost of the entire pressure switch can be reduced.

이상과 같이 본 고안은 개, 폐작동 접점을 하나로 하고, 공통단자편을 별도로 설치 구성하여 전원이 오프된 상태에서 별도의 타회로를 제어시킬 수 있도록 하며, 접점 개폐시 스파크에 의한 절연파괴의 위험을 배제시킬 수 있는 유용하고도 실용적인 고안이다.As described above, the present invention has one open and closed operation contact point, and a common terminal piece is separately installed and configured to control another circuit in a power-off state. It is a useful and practical design to eliminate the problem.
