Description

압력스위치의 접점장치Pressure switch contact device

제1도는 본 고안의 분해사시도.1 is an exploded perspective view of the present invention.

제2도는 본 고안의 요부 작동 예시단면도.Figure 2 is a sectional view showing the main operation of the present invention.

제3도는 종래것의 요부 작동 예시도.3 is an illustration of the main operation of the conventional.

본 고안은 다이어프램(Diaphragm)과 같은 압력장치에 의하여 접점단자를 작동하게 된 압력 스위치의 접점장치에 관한 것으로, 종래에는 다이어프램에 의하여 상하 작동되는 작동대 상방에 괘삽된 접점편의 양단에 접점단자를 형성하여 이 접점단자를 인입과 배전단자에 각기 접지되게 하였기 때문에 제3도에 표시된 바와 같이 접점편(a)을 받쳐주는 스프링(b)의 탄발력이 접점편(a)을 고른 압력으로 탄발시키지 못하는 관계로 접점단자(c)(c′)가 인입단자(d)와 배전단자(e)에 고른 압력으로 접지되지 못하므로 접지되는 순간에 전하가 소멸하는 불꽃방전(Spark Discharge)의 현상이 일어나는 결접이 있고 국내 실용신안공보 제388호 제41페이지에 실린 공고번호 제78-1600호(명칭 : 압력스위치)는 상부체 저면에 나사홈이 형성된 돌출부를 형성하고 하부체에는 나사홈이 형성된 요입부를 형성하여 다이어프램을 요입부에 대고 상하부체를 고정나사로 체결하게된 다이어프램을 견고하게 부착함을 주목적으로 한 것으로써 도면상으로 보아 인입접점에 배전접점만을 접지 단락하도록 되어있으나 다이어프램의 작동으로 상승되는 압간의 상승동작에 따라 작동판은 작동편의 탄성 반발력에 의하여 하강되면서 견인간(12)을 당기어 도선의 스위치 접점들을 분리시켜 단전하게 하고 스프링의 탄발력으로 압간이 다이어프램을 누르고 하강되면서 작동판은 상승되어 다시 접점을 하게 되는 것으로 그 구조가 복잡하여 제작이 번거로울 뿐만 아니라 상하 작동되는 견인간에 접점을 형성하였으므로 이 견인간을 작동시키는 작동판과 작동편의 반발탄력의 원활치 못한 작동으로 접점을 부착한 견인간 상하작동의 간격이 일정치 못할 경우 접점의 접지 상태가 양호치 못한 결점이 있는 것이다.The present invention relates to a contact device of a pressure switch to operate the contact terminal by a pressure device such as a diaphragm (Diaphragm), conventionally forming contact terminals on both ends of the contact piece that is inserted above the operating table vertically operated by the diaphragm Since the contact terminals are grounded to the lead-in and distribution terminals, respectively, as shown in FIG. 3, the elasticity of the spring (b) supporting the contact piece (a) does not cause the contact piece (a) to be released at an even pressure. As a result, the contact terminal (c) (c ') is not grounded at equal pressure on the lead terminal (d) and the distribution terminal (e), so the spark discharge phenomenon occurs in which the charge disappears at the moment of grounding. Publication No. 78-1600 (name: pressure switch), which is published in Korean Utility Model Publication No. 388, page 41, forms a projection with a screw groove formed on the bottom of the upper body, and a screw groove on the lower body. The main purpose is to form the concave indentation and attach the diaphragm firmly to the concave inlet and to secure the diaphragm fastened to the upper and lower parts with the fixing screw. The operation plate is lowered by the elastic repulsive force of the operating piece while pulling up the towing lever 12 to separate the switch contacts of the conductors, and to make it work by pressing the diaphragm. The plate is raised and re-contacted, and its structure is complicated, and it is not only cumbersome to manufacture, but also forms a contact between the towing operated up and down. The interval between the up and down movements between one towing If you do, there is a fault that the grounding of the contact is not good.

본 고안은 이와 같은 결점을 시정하기 위하여 안출한 것으로 첨부 도면에 의하여 그 구조를 상세히 설명하면 다음과 같다.The present invention has been devised to correct such drawbacks and the structure thereof will be described in detail with reference to the accompanying drawings.

하부체(1)상에 케이스(2)를 덮어 보울트로 고정되게 하고 하부체(1) 상면에 인입선(3)과 배전선(4)을 연결하는 인입단자편(5)과 배전단자편(6)을 부착하는 고정대(7)를 입설하여 하부체(1)의 내공(1′)과 고정대(7)의 구멍(7′)을 관통되게 수직으로 장설된 견인간(8)의 외방으로 코일스프링(9)을 감삽하여서 된 종래의 것에 있어서, 견인간(8)의 상방에 형성된 걸림턱(8′)에 괘삽된 탄편(10)의 일단부(10a)는 인입단자편(5)에 리벳트(11)로 연결하고 탄편(10)의 타단부(10b)에는 단자(12)를 형성하여 견인간(8)에 감삽된 코일스프링(9)으로 하여금 탄편(10)을 상향되도록 탄설하여서 구성된 것이다.An inlet terminal piece 5 and a distribution terminal piece 6 covering the case 2 on the lower body 1 to be fixed with a bolt and connecting the inlet line 3 and the distribution line 4 to the upper surface of the lower body 1. The coil spring is inserted into the outside of the towing section 8 installed vertically so as to penetrate the inner hole 1 'of the lower body 1 and the hole 7' of the fixing member 7 by attaching the fixing member 7 attached thereto. In the conventional one made by subtracting 9), one end portion 10a of the bullet piece 10 which is hooked to the engaging jaw 8 'formed above the towing section 8 is riveted to the inlet terminal piece 5. 11) and a terminal 12 is formed at the other end 10b of the coal piece 10 so that the coil spring 9, which is interpolated in the towing section 8, is coalesced so that the coal piece 10 is upward.

이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as follows.

공지의 다이어프램에 연결된 견인간(8)이 하강되면 제2도와 같이 걸림턱(8′)에 의하여 탄편(10)의 타단부(10b)가 경사 방향으로 내려가 배전단자편(6)의 단자로부터 단자(12)를 떨어지게 하여 단전하게 하고 견인간(8)이 상승되면 코일스프링(9)의 탄발력으로 경사지게 내려간 탄편(10)의 타단부(10b)가 상승되어 단자(12)가 배전단자편(6)의 단자에 접지되어 통전하게 되는 것이다.When the towing section 8 connected to the known diaphragm is lowered, the other end 10b of the bullet piece 10 is lowered in the inclined direction by the locking jaw 8 'as shown in FIG. 2 and the terminal from the terminal of the distribution terminal piece 6 When the towing section 8 is raised and the towing section 8 is raised, the other end 10b of the piece 10 which is inclined down by the resilient force of the coil spring 9 is raised so that the terminal 12 is connected to the distribution terminal piece. It is grounded and energized to the terminal of 6).

이와 같이 본 고안은 탄편(10)의 일단부(10a)를 인입단자편(5)에 고정시키고 타단부(10b)만을 견인간(8)과 코일스프링(9)에 의하여 상하 작동되게 함으로써 단자(12)를 배전단자편(6)의 단자에 접지 또는 단락되게 하였기 때문에 그 구조가 종래의 것보다는 간단하여 제작이 용이할 뿐만 아니라 코일스프링(9)의 탄발력이 탄편(10)의 타단부(10b)만을 탄발되게 함으로써 종래 2개의 단자를 형성한 접점편을 탄발되게 한 것보다는 그 단자 접지력을 강화시켜 단자접지 또는 탈락시 불꽃방전이 일어나지 않는 장점이 있는 것이다.As such, the present invention fixes the one end portion 10a of the bullet piece 10 to the inlet terminal piece 5 and allows only the other end portion 10b to be operated up and down by the traction rod 8 and the coil spring 9. Since 12) is grounded or short-circuited to the terminals of the distribution terminal piece 6, the structure thereof is simpler than the conventional one, so that it is easy to manufacture and the elasticity of the coil spring 9 is different from the other end of the bullet piece 10. 10b) has only an advantage that the sparking discharge does not occur during terminal grounding or dropping by strengthening the terminal grounding force rather than causing the contact piece having two terminals formed in the related art.
