装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical coupling device that combines a light emitting element and a light receiving element, that is, a photocoupler. The present invention relates to an optical coupling device having a structure in which a light emitting part of an element pellet and a light receiving part of a light receiving element pellet are fixed to a transparent insulating plate so that both pellets face each other.

素子で受けて、信号を伝達する装置であり、入力
側と出力側とを電気的に分離できる利点がある。
したがつて、このためには入出力間に高い絶縁耐
圧が要求される。 A photocoupler, or photocoupler, is a device that receives light emitted from an input side, that is, a light emitting element, and transmits a signal to an output side, that is, a light receiving element, and has the advantage of being able to electrically separate the input side and output side. .
Therefore, for this purpose, a high dielectric strength voltage is required between input and output.

平板が大きくなるために割れやすく、取り扱いに
くくなり、また、パツケージが大きくなるという
短所がある。従つて、前述の構造のホトカプラに
おいて、コンパクトなパツケージのまま、入出力
間の絶縁耐圧を高めることには限界があつた。 Conventional photocouplers with the above structure usually use a flat light-transmitting insulating plate as the light-transmitting insulating plate, so dielectric breakdown occurs at a relatively low voltage through the end face of the flat light-transmitting insulating plate. The drawback is that the insulation voltage between input and output is low. In addition, in order to compensate for the drawback of low insulation voltage between input and output,
There is a method of increasing the area of the transparent insulating flat plate and increasing the distance along the surface of the insulating flat plate from the input side to the output side, but this method makes the transparent insulating flat plate large and easy to break. , it becomes difficult to handle, and the package size becomes large. Therefore, in the photocoupler having the above structure, there is a limit to increasing the dielectric strength between the input and output while maintaining a compact package.

ある。 In addition, as a photocoupler with high dielectric strength between input and output, there is a photocoupler with a structure that uses an optical fiber in the coupling part that transmits the light emitted from the light emitting element to the light receiving element. The light emitting element,
The current transfer rate, which is the ratio of input current to output current, is lower than that of photocouplers, which have a structure in which both pellets of the light-receiving element are fixed to the light-transmitting insulating plate, and the output current is
It is inconvenient to use because it cannot be taken out much.

欠点を取り除きパツケージの大きさを変えること
なく、電流伝達率が高く、さらに入出力間の絶縁
耐圧の高いホトカプラを提供することである。 The object of the present invention is to eliminate the above-mentioned drawbacks of the conventional photocouplers, which have a structure in which a light-emitting element pellet and a light-receiving element pellet are fixed to a light-transmitting insulating plate by sandwiching a light-transmitting insulating plate, and to change the size of the package. It is an object of the present invention to provide a photocoupler which has a high current transfer rate and a high dielectric strength between input and output.

ラが得られる。 The above-mentioned object of the present invention is achieved by using a light-transmitting insulating plate having a refraction portion as a light-transmitting insulating plate. According to the present invention, since the distance from the input side pellet to the output side pellet along the surface of the transparent insulating plate is longer, the input/output dielectric strength voltage is increased.
In addition, the distance along the surface is lengthened not by using a flat translucent insulating plate with a large area, but by using a translucent insulating plate with a bending part, so the size of the package does not change. A photocoupler that is not available can be obtained.

れた。[Example 1] In the photocoupler of the first example of the present invention, a light emitting element pellet and a light receiving element pellet are first mounted and bonded on separate frames, and then
Next, as shown in FIG. 1a, the light emitting element pellet 1
The light emitting element pellet 1 is placed so that the light emitting part of the light receiving element pellet 3 and the light receiving part of the light receiving element pellet 12 face each other.
3. The light-receiving element pellet 12 is fixed to a light-transmitting insulating plate 15 made of borosilicate glass or the like having the shape shown in FIG. 1b. Then, it is molded with an opaque resin (not shown) and packaged. The dielectric strength voltage between the input and output of the photocoupler made in this way was measured, and it was found that it was higher than that of a photocoupler with a structure using a transparent insulating plate without a refractive part, that is, a transparent insulating flat plate with only the BEHC part in Figure 1 b. , a much higher input-output insulation voltage was measured, and a significant improvement was observed.

高くここに著しい改善が認められた。[Example 2] The photocoupler of the second example according to the present invention is
As shown in FIG.
The light emitting part of the light receiving element beret 22 and the light receiving part of the light receiving element belet 22 are fixed to the light transmitting insulating plate 25 so as to face each other with the light transmitting insulating plate 25 having a bending part interposed therebetween.
Then, packaging is performed by molding with an opaque resin (not shown). The light emitting element pellet 23 of the photocoupler of this structure has two electrodes taken out from the non-light emitting side of the pellet. The insulation voltage between the input and output of the photocoupler manufactured as described above was measured. As a result, ABCD in Figure 2b
A photocoupler using a translucent insulating plate with a refraction part shaped as shown in Figure 2b has better insulation between input and output than a photocoupler using a translucent insulating plate with only the BEGC part without the and EFGH parts. The pressure resistance was much higher, and a significant improvement was observed here.

しい。 In the above two embodiments, a structure is shown in which the light-transmitting insulating plate has a refraction portion on both sides, but it goes without saying that a structure in which one of the refraction portions is omitted may be used in order to simplify manufacturing. To give an example of specific dimensions in that case, referring to Figure 1b, the distance between BE is 1 mm, the distance between CD is 0.5 mm, the distance between AD is 1.2 mm, and the thickness is 0.1 mm.
It can be mm. The respective distances between BE and AD are designed based on the sizes of the light emitting and light receiving pellets, and the distance between CD is preferably selected to be the sum of the thickness of the pellet and the thickness of the frame.
