1a), this misalignment is caused by the fact that the internal light guide (9) has a long glazed shape and is easily bent in a direction perpendicular to its longitudinal direction. Therefore, if the light guide support (
If there is no light guide 121, the internal light guide (9) will vibrate, causing a misalignment with the light receiving section (1a), and the trigger light signal will not be sufficiently transmitted to the light receiving section (1a). This internal light guide (9) may cause ignition delay or ignition failure of the thyristor, or in some cases,
There is a possibility that the pJ will resonate and break.

折れ、歩留まりが悪いという欠点があった。Now, the procedure for assembling this light-triggered thyristor is to first attach the internal light guide (9) to which the light guide sleeve a (o is attached) and the first electrode body (2) to the 7 flange (51
The light guide support +1 is attached to the through hole (8) of the insulating cylinder (4) with high temperature solder etc.
The method is to fit the hole 2) into the tip of the internal light guide (9) and then fit it into the cylindrical step part (11) provided at the center of the first electrode body (2). At this time, the tip of the internal light guide (9) is not necessarily located exactly in the center of the cylindrical step part (111).
Therefore, when the light guide support body 0 was fitted, the internal light guide (9) was bent to some extent. However, as mentioned earlier, the internal light guide (9) flexes well in the direction perpendicular to its longitudinal direction, so there was no problem. It was easily broken. For example, with a diameter of 1.5 rran and a longitudinal length of 50 rmn,
The internal light guide (9) made of multi-component glass with a height of 10 mm in the perpendicular direction did not break even if it was bent by about 0.3 ram in the longitudinal direction and the perpendicular direction, but it did not break by 0.3 ram in the longitudinal direction. The internal light guide (9
) had the disadvantage that the light guide support (121) was often bent when fitted into it, resulting in poor yield.

トリガサイリスタを提供することを目的としている。The present invention has been made in view of the above-mentioned points, and provides a light-triggered thyristor with a high yield rate during assembly by improving the fixing structure of the light guide support so that the internal light guide does not break. It is an object.

A hole with the same diameter as the tip diameter of 9) is made, and has the same width as the rectangular step part (21), and the length in the longitudinal direction of the internal light guide (9) is equal to the rectangular step part + 21.

なるような位置ずれを起こすことはない。In the structure of this embodiment, the internal light guide (9
), i.e. the internal light guide (
Since the width of the rectangular step part (2D and the rectangular light guide support color are the same), the direction in which the inner light guide (9) is easy to bend is the same, so it is possible to prevent positional shift due to vibration etc. i.e. internal light guide (9)
The direction in which the inner light guide (9) is more likely to break is made by shortening the length of the rectangular light guide support (support) relative to the rectangular step section &l) so that it can move to some extent in the direction in which it is more likely to break. There will be no more folding. In addition, the internal light guide (9) deflects in this direction with respect to positional deviation due to longitudinal vibration, etc., which can be ignored. Even if the structure can move in any direction, it will not cause any positional deviation that would cause problems.

However, this structure is not limited to this, and as shown in Figure 3, a rectangular step (21) is used.
A circular light guide support (121
may also be used. Furthermore, as shown in Fig. 4, the cylindrical step part (
A light guide support (42) having an oblong guide hole having the same width as the diameter of the tip of the internal light guide (9) and parallel to the horizontal groove (7) in 11) may also be used. In this case, the weight of the end of the internal light guide (9) is eliminated against the longitudinal vibration of the internal light guide (9), and the resonance point can be further raised. It is preferable to fix the stepped portion αυ and the light guide support (42) using a right-hand adhesive or the like, or to use a polygonal stepped portion and the light guide support so that the direction does not shift.

ことができる効果がある。As described above, the optical trigger thyristor of this invention has the following characteristics:
The tip of the internal light guide on the light-receiving section side is restrained from moving in the direction perpendicular to the longitudinal direction of the internal light guide, but is movable in the longitudinal direction, so that it can be easily moved when using the device. This has the effect of being able to prevent misalignment between the internal light guide and the light receiving section due to vibrations, etc., and to provide a light trigger thyristor in which the internal light guide does not break during assembly.

Representative Katayuni 8 Part 4, Claims in the attorney's specification 6, Contents of the amendment Patent Claims (1) A basic element having a light-receiving part for a light trigger in the center of one main surface, first and second electrode bodies that sandwich the basic element, and the basic element surrounding the outer periphery of the basic element. An insulating cylinder is airtightly fixed to the first and second electrode bodies, and the first electrode body is formed with an opening toward the basic element side, extending in the radial direction of a part of the outer peripheral surface of the first electrode body, and extending beyond the light receiving part. an internal light guide disposed within the horizontal groove with one end proximate to the light receiving section and the other end drawn out to the outside of the insulating cylinder and transmitting a light trigger signal from the outside to the light receiving section; , light guide support means for restraining the light-receiving section side end of the internal light guide against movement in a direction perpendicular to the longitudinal direction of the internal light guide, and making it free against movement in the longitudinal direction. A light-triggered scissor characterized by: (2) The light guide support means includes a rectangular step portion formed along the longitudinal direction of the internal light guide at the center of the surface of the first electrode body that comes into contact with the basic element, and the rectangular step portion. 1. A light guide having a thickness equal to the depth of the stepped portion and having a hole in the center thereof which is slidably fitted in the longitudinal direction and into which the end of the internal light guide is inserted. The photo-triggered scissor according to claim 1, characterized in that it comprises a support. (3) - The light guide support means is fixedly embedded in the center of the surface of the first electrode body that comes into contact with the heshinok element, and the light guide support means is fixedly buried in the center of the surface of the first electrode body that comes into contact with the Heshinok element, and has the same diameter as the tip of the inner light guide. The optical trigger xylisk according to claim 1, comprising a light guide support having an elongated hole whose width is elongated in the longitudinal direction of the guide.
