Abstract

PURPOSE:To prevent the intrusion of dust into an optical oil in an optical branching device injected with the optical oil into the inclined gap provided to a photoconductor by interrupting the communication between the optical oil and the external air. CONSTITUTION:A through-hole is bored to the 1st photoconductor rod in the diametral direction thereof and the 2nd photoconductor rod 2 and the 3rd photoconductor rod 3 are fitted into the through-hole, then the rod 2 is fixed. Slopes 2a and 3a are formed to the rod 2 and the rod 3. A groove 3b is provided to the top end of the rod 3 and the optical oil 5 is injected into the spacing (d) between the slopes 2a and 3a through the groove 3b. A cover member 10 is liquid-tightly fixed to the rod 1 in a manner as to cover the slope 3a of the rod 3 and the end 3c on the opposite side and the optical oil 11 is sealed into the member 10. The spacing (d) is adjusted by moving the rod 3 to adjust the quantity of the light branched to the 4th photoconductor rod 4.

等の欠点があった。The light that has been propagated in the direction of the arrow inside the first light guide rod 1 is
The light is reflected by the inclined surface 20 of the second light guide rod 2 and travels in the direction of arrow B, and travels in the direction of arrow C in the part where the optical oil is contained, but at this time, the amount of light traveling in the direction of arrow B is within the gap. can be adjusted by the level of the optical oil 5 in the optical oil 5, and this can be adjusted by the insertion depth of the third light guide rod 3. 4 is a fourth light guide rod fixed to the outer peripheral surface of the light guide rod 1, covering the fitting portion of the second light guide rod 2, or formed integrally with the second light guide rod; The light branched in the direction of arrow B as described above is taken out through the fourth light guide rod 4 and sent to any desired location through a light guide cable (not shown) connected to the fourth light guide rod 4. It is transmitted and used for lighting and other uses. However, in the above optical branching device, the optical oil 5 between the inclined surfaces communicates with the atmosphere through the groove 3q provided in the third light guide rod 3, and the optical oil may leak through the straight groove 3a, or
There is a drawback that dust in the outside air gets mixed into the optical oil through the straight groove 3a, making it impossible to withstand use for many years. Furthermore, since the groove 30 is an air layer, light scattering occurs there, resulting in a large loss of optical energy.

The same reference numerals as in FIG. 4 are provided. 1 and 2, 10 is attached to the first light guide rod 1 in a liquid-tight manner so as to cover the end 3c side of the third light guide rod 3 opposite to the inclined surface 3a side. A cover member 10 is fixed to the optical oil 11 inside the cover member lO.
is included. Further, a permanent magnet 15 is integrally attached to the protruding end 3c side of the third light guide rod 3, and a permanent magnet 16 of opposite polarity is provided on the outside of the cover 10, facing the permanent magnet 15. It is mounted so as to be movable in the axial direction of the third light guide rod 3. Therefore,
When the permanent magnet 16 is moved in the direction of arrow E, the third light guide rod 3 is also moved in the direction of arrow E, and the inclined surface of the second light guide rod 2 and the inclined surface of the third light guide rod 3 are separated. On the other hand, if the third light guide rod 3 moves in the direction of arrow F, the distance between the inclined surfaces becomes wider. Similarly, the light energy propagated in the direction of the arrow in the light guide rod 1 can be branched in the direction of the arrow B or the direction of the arrow C.

。In addition, at this time, when the distance d between the inclined surfaces is minimized, the groove 3b provided in the third light guide rod 3 is filled with the optical oil 5, and conversely, when the distance d between the inclined surfaces is By filling the groove 3b with the optical oil 11 when the optical oil 11 is at its maximum, scattering of light energy at the groove 3b portion is reduced, and loss of light energy can be reduced. 1
Reference numeral 3 denotes a stopper/volume adjustment screw provided on the cover 10. The screw 13 is operated from the outside of the cover 10 to regulate the amount of protrusion into the cover. In addition to regulating the movement in the direction, the volume of the portion of the cover member containing the optical oil is adjusted, so that when the third light guide rod 3 is moved in the direction of arrow F, the optical oil 11 is in the groove 3b. I try to adjust the amount that goes into it. It should be noted that it is easy to understand that the stopper function and the volume adjustment function may be constructed from separate members.
