Abstract

PURPOSE:To obtain a switch of simple structure which operates securely and is manufactured at low cost by coupling fixed optical fibers and a moving optical fiber selectively through a gap. CONSTITUTION:A switcher 2 is stopped at the upper end of a slide groove 1 firstly. In this case, a fixed-side optical fiber 3a and the optical fiber 4 fixed to the switcher 2 are coupled together optically through the gap between facing surfaces 1a and 2a. The switcher 2 is stopped at the 1st stable point. When a push button 5 is pressed in, an end part of a supporting lever 6a is pressed down with the push button 5 to draw a spring 9 which links supporting levers 6a and 6b together, and the button 5 is further pressed down until the operating line of the force of the spring 9 goes beyond a pin 7, pressing down the supporting lever 6b abruptly by the tension of the spring 9. Then, the switcher 2 is pressed down abruptly and stopped at the lower end of the slide groove 1. Thus, the tip 4a of the fiber 4 is switched between fibers 3a and 3b.

られて伝送するので、光スィッチを構成する。At this time, the fixed side optical fiber 3'a and the optical fiber 4 fixed to the switch 2 are optically coupled through the gap between the opposing surfaces 1a and 2a. That is, the switching element 2 is stopped at the first stable point, which is one of the two stable points of the drive device. Next, when the push button 5 of the operating section of the drive device is pushed in, the end of the support frame 6a is pushed down by the push button 5,
When the spring 9 that connects the support frame 6a and the support frame 6b is tensioned and the push button 5 is further pushed down, the line of action of the spring 9 passes over the pin 7, and the support frame 6b of the drive unit is suddenly released from the spring. It is pushed down with a tension of 9. This causes the switch 2 to switch to the bin 8.
Since the switch 2 is connected to the support frame 6b by the switch 2, the switch 2 is suddenly pushed down and stopped at the lower end of the sliding groove 1. That is, the switch 2 stops at the second stable point. The switch 2 moves along the sliding groove from a first stable point to a second stable point, and the moving distance is equal to the spacing between the optical fibers 3a and 3b. Therefore, when the switch 2 stops at the second stable point, the optical fiber 3b and the optical fiber 4 on the switch 2 are optically coupled. The light transmitted through the optical fiber 4 by the snap action of the drive device as described above first passes through one optical fiber 3a.
The signal is transmitted to the optical fiber 3b, and then switched to the other optical fiber 3b for transmission, thus forming an optical switch.

In FIG. 2, the same numbers as in FIG. 1 indicate the same parts. 12 indicates a bistable leaf spring. In FIG. 2, when the push button 5 of the operating section is pushed down, the leaf spring 12 of the drive section is pushed down with one curvature, and after passing a certain point, the curvature suddenly reverses and the switch 2 is suddenly pushed down. Move to second stable point. Therefore, the optical fiber 4 is abruptly switched from coupling with the optical fiber 3a to the optical fiber 3b. Furthermore, the second
Also in the figure, if the push button 5 and the return spring 10 are provided in symmetrical positions with respect to the horizontal line passing through the base of the leaf spring 12, the switch 2 can be reversed and the optical fiber 4 can be connected to the optical fiber 3.

する効果がある。In addition, the switching element 2 moves accurately between two stable points by the snap action of the drive device, and does not cause chattering or optical axis misalignment between the optical fibers when the switching element 2 stops moving. In addition, the curved portion 11° between the moving end of the 40 optical fibers fixed to the switch 2 and the fixed base is kept free without being constrained by the surroundings, so it is easy to switch the switch 2. This curved portion 11 absorbs the bending strain that occurs in the optical fiber 4 due to the accompanying movement of the tip of the optical fiber 4, so that it has the effect of alleviating the sudden movement and strain of the optical fiber 4.

In the optical fiber switch according to the present invention shown in FIG. 3, the switching element 13 is driven in one direction by electromagnetic force and restored by the force of a spring. Normally, the switching element 13 is pushed up by a spring 15, and the optical fiber 4 is fixed with its open end exposed on the opposing surface 13a of the switching element 130, and with its open end exposed on the opposing surface 1a on the fixed end side. Optical fiber 3a and opposing surface 1
They are optically coupled through a slight gap between a and 13a. Next, when a driving current is applied to the electromagnetic coil 14, the switching element 13 is attracted by electromagnetic force, and the switching element 13 is stopped at a position where it is attracted to the electromagnetic coil 14. At this position, the open end of the optical fiber 4 fixed to the switch 13 is connected to the optical fiber 3.
b and are optically coupled via a slight gap between the facing surfaces 1a and 13a. Therefore, the optical signal propagating through the optical fiber 4 is propagated by being switched from the optical fiber 3a to the optical fiber 3b.

Furthermore, the switching element 13 moves accurately between two stable points, and does not cause chattering or optical axis misalignment between the optical fibers when it stops moving. Furthermore, since there is a curved portion 11 that is not constrained by the periphery between the end 4a of the optical fiber 4 fixed to the switch 13 and the fixed base, the switch 1

る光フアイバスイッチ。A fixed optical fiber or optical fibers having an open end along one opposing surface, and an opposing surface facing the above opposing surface with a slight gap between them, allowing jumping between different stable points. a moving switching element, a drive device for jumping the switching element between said different stable points, an end fixed to said switching element, and a base fixed irrespective of movement of said switching element; , one or more optical fibers having a curved portion not supported from the surroundings between the end portion and the base, having an open end on a surface facing the switching element, and moving with the movement of the switching element. An optical fiber switch characterized in that, at the different stable points, the fixed optical fiber and the moving optical fiber are selectively coupled via a gap between the opposing surfaces.
