광 통신 시스템은 고속, 고성능의 정보 전달을 가능케 하는데, 예를 들면, 초당 100∼2,500 메가 펄스까지도 전송할 수있다. 이러한 광 전송의 방향을 바꾸어 주는 스위치는 보통 입력(M개)과 출력(N개)의 개수로 정의된다.Optical communication systems enable high-speed, high-performance information transfer, for example up to 100 to 2,500 megapulses per second. The switch for changing the direction of the optical transmission is usually defined by the number of inputs (M) and outputs (N).
도 1a는 일반적인 광 스위치에서 사용되는 레이아웃(layout) 구조로서, 입력이 2개, 출력이 2개인 2 ×2 매트릭스 구조의 광 스위치를 나타낸다.FIG. 1A is a layout structure used in a general optical switch, and illustrates an optical switch having a 2 × 2 matrix structure having two inputs and two outputs.
도 1a를 참조하면, 각각의 엑츄에이터(actuator)의 끝에는 45°의 각도로 기울어진 거울면(13a∼13d)들이 있어, 빛이 입사할 경우 이를 반사(reflection)시키는 기능을 가지고 있으며, 광 섬유 A(181), 광 섬유 B(182)에서 나온 광이 엑츄에이터 a(111)와 엑츄에이터 d(114)의 ON 방향 작동에 의하여 제1 거울면(mirror surface)(13a)과 제4 거울면(13d)이 앞으로튀어나와 광 경로(optical path)를 변환시킴으로써, 광 섬유 C(183)와 광섬유 D(184)로 각각 입사되는 것을 보여준다.Referring to Figure 1a, at the end of each actuator (actuator) has a mirror surface (13a to 13d) inclined at an angle of 45 °, it has a function to reflect (reflection) when light is incident, the optical fiber A 181, the light from the optical fiber B 182 is moved by the ON direction of the actuator a (111) and the actuator d (114) in the first mirror surface 13a and the fourth mirror surface 13d. By popping this forward and converting the optical path, it is shown to be incident on the optical fiber C 183 and the optical fiber D 184, respectively.
도 1b를 참조하면, 광 섬유 A(181), 광 섬유 B(182)에서 나온 광이 엑츄에이터 b(112), 엑츄에이터 c(113)의 ON 방향 작동에 의하여, 제2 거울면(13b)과 제3 거울면(13c)이 앞으로 튀어나와 광 경로를 변환시킴으로써, 광 섬유 D(184), 광 섬유 C(183)로 각각 입사되는 것을 나타낸다.Referring to FIG. 1B, the light from the optical fiber A 181 and the optical fiber B 182 is driven by the ON direction of the actuator b 112 and the actuator c 113 to operate the second mirror surface 13b and the first mirror. The three mirror surfaces 13c protrude forward and change the optical path, indicating that they enter the optical fiber D 184 and the optical fiber C 183, respectively.
이와같은 종래의 광스위치는 광데이타 전송 제어과정에서 랫치-업 기능을 수행할 경우 액츄에이터(112,113)의 동작을 제어하기 위한 전기적 신호를 발생시켜야 하며 외부 진동이 주어질 경우 동작이 불안정해져 광데이타 전송제어상의 문제점을 지니고 있었다.Such a conventional optical switch has to generate an electrical signal for controlling the operation of the actuators 112 and 113 when the latch-up function is performed in the optical data transmission control process. I had a problem.
따라서, 본 발명은 상기의 문제점을 해결하기 위해 창안된 것으로서, 본 발명의 목적은 광데이타 전송제어를 위한 광스위치의 랫치-업 기능을 수행하기 위한 구조가 간단하며 그 기능이 기계적인 동작 방식을 채택하여 동작 안정성이 보다 향상된 랫치-업 기능이 구비된 광스위치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is a simple structure for performing a latch-up function of an optical switch for optical data transmission control, and its function is a mechanical operation method.

상기 도면에 도시된 바와같이, 이동되지 않는 고정전극(10)과 상기고정전극(10)과의 정전력으로 이동 동작되는 가동전극(20)이 구성되어 있으며 상기 가동전극(20)과 일체로 형성되며 중앙부에는 외부로 돌출된 걸림턱부재(31)가 형성되고 일측 끝단부에는 원형봉(32)이 구비된 가동구조체(30)가 구성되어 있다.As shown in the figure, the movable electrode 20 which is moved by the constant power between the fixed electrode 10 and the fixed electrode 10 which is not moved is configured and is formed integrally with the movable electrode 20. The center portion is formed with a locking projection member 31 protruding to the outside and the movable structure 30 having a circular rod 32 is formed at one end portion.
즉, 상기 가동구조체(30)의 중앙부에는 외측으로 돌출 형성되며 그 모양이 "삼각뿔" 형상으로 이루어진 걸림턱부재(31)가 구성되어 있다.That is, a locking jaw member 31 is formed at the center of the movable structure 30 to protrude outward and its shape is formed in a "triangular pyramid" shape.
한편, 이와 대응되게 이동되지 않는 고정전극(10')과 상기 고정전극(10')과의 정전력으로 이동 동작되는 가동전극(20')이 구성되어 있으며 상기 가동전극(20')과 일체로 형성되며 그 모양이 "쐐기" 형상으로 이루어진 가동구조체 복귀부재(40)가 형성되어 있다.Meanwhile, the fixed electrode 10 'which is not moved corresponding to the movable electrode 20' which is moved by the electrostatic force between the fixed electrode 10 'and the fixed electrode 10' is configured to be integrated with the movable electrode 20 '. A movable structure return member 40 is formed and has a shape of a “wedge” shape.
즉, 상기 가동구조체 복귀부재는 가동전극(20')의 이동시 상기 원형봉(32)과 접촉하게 되면 걸림턱부재(31)가 걸림홈(33)에 이탈되어 가동구조체(30)를 복귀시키도록 구성되어 있다.That is, when the movable structure returning member comes into contact with the circular rod 32 when the movable electrode 20 'is moved, the locking jaw member 31 is separated from the locking groove 33 to return the movable structure 30. Consists of.
상기와 같이 구성된 본 발명의 랫치-업 기능이 구비된 광스위치의 동작을 설명하면 다음과 같다.Referring to the operation of the optical switch with a latch-up function of the present invention configured as described above are as follows.
엑츄에이터를 구성하는 가동전극(20)은 인가 전압 유무에 따라 가동전극(20)과 고정전극(10)간에 발생되는 정전력(electrostatic force)에 의해 전/후진 동작을 하게 되는데 상기 가동전극(20)과 고정전극(10)간에 흡인력이 발생하면 후진동작을 하게 되는데, 이과정에서 걸림턱부재(31)가 걸림홈(33)에 삽입되어 고정/지지되어 이동을 멈추게 된다.The movable electrode 20 constituting the actuator is moved forward / backward by electrostatic force generated between the movable electrode 20 and the fixed electrode 10 according to the presence or absence of an applied voltage. The movable electrode 20 When a suction force is generated between the fixed electrode and the fixed electrode 10, the reverse operation is performed. In this process, the locking jaw member 31 is inserted into the locking groove 33 to be fixed / supported to stop the movement.
따라서, 외부 제어신호에 따라 양 전극(10.20)간에 정전력을 발생하게 되면액츄에이터는 랫치-업되어 광데이타 전송을 제어하게 된다.Therefore, when the electrostatic force is generated between the electrodes 10.20 according to the external control signal, the actuator is latched up to control the optical data transmission.
이와는 반대로, 엑츄에이터를 구성하는 가동전극(20')은 인가 전압 유무에 따라 가동전극(20')과 고정전극(10')간에 발생되는 정전력(electrostatic force)에 의해 전/후진 동작을 하게 되는데 상기 가동전극(20)과 고정전극(10)간에 흡인력이 발생하면 가동구조체 복귀부재(40)는 전진동작을 하게 되고, 이에따라 상기 원형봉(32)과 접촉 동작시 걸림턱부재(31)가 걸림홈(33)에 이탈되어 가동구조체(30)를 복귀시키게 된다.On the contrary, the movable electrode 20 'constituting the actuator performs forward / backward operation by electrostatic force generated between the movable electrode 20' and the fixed electrode 10 'according to the presence or absence of an applied voltage. When a suction force is generated between the movable electrode 20 and the fixed electrode 10, the movable structure return member 40 is moved forward, and accordingly the locking jaw member 31 is caught in contact with the circular rod 32. The groove 33 is separated to return the movable structure 30.
이상에서와 같이, 외부 제어신호를 받게 되면 가동전극(20.20')과 고정전극(10,10')간에는 정전력이 발생하게 되고, 이에따라 가동구조체(30)와 가동구조체 복귀부재(40)가 전진 또는 후진 동작되어 액츄에이터를 동작시켜 광데이타 전송을 제어할수 있게 된다.As described above, when the external control signal is received, the electrostatic force is generated between the movable electrodes 20.20 'and the fixed electrodes 10, 10', and thus the movable structure 30 and the movable structure return member 40 are advanced. Alternatively, the reverse operation may be performed to control the optical data transmission by operating the actuator.
이상 설명한 바와 같이 본 발명에 의하면, 광데이타 전송제어를 위한 광스위치의 랫치-업 기능을 수행하기 위한 구조가 간단하며 그 기능이 기계적인 동작 방식을 채택하여 동작 안정성이 보다 향상된 랫치-업 기능이 구비된 광스위치를 제공할수 있는 효과를 지니고 있다.As described above, according to the present invention, the structure for performing the latch-up function of the optical switch for optical data transmission control is simple, and its function adopts the mechanical operation method, so that the latch-up function is improved. Has the effect of providing an optical switch provided.
