達効率が格段に低下する。 Recently, we have entered an era of energy conservation, and research and development is being conducted in various fields on the effective use of solar energy. The applicant was one of the first to notice the effective use of solar energy, and has already made various proposals. , the use of energy without converting it into other forms of energy such as electricity or heat. Therefore, the present applicant has proposed that solar energy be focused and introduced into a light guide cable, and guided through the light guide cable to a location that requires illumination to provide illumination. In this way, by transmitting solar energy using a light conductor cable and illuminating with solar energy, there is no conversion loss and the like, and solar energy can be used most efficiently. but,
In order to transmit the collected solar energy to a long distance, it is necessary to connect several light conductor cables, and if the transmission efficiency at the connection point is poor,
It became almost unusable,
For example, the transmission efficiency in the case of only the core part is about 78%,
The transmission efficiency when a cladding layer is included is 35%, so if there are five connections, the transmission rate of optical energy is approximately 29% or less when the core is included, and when a cladding layer is included, the transmission efficiency is approximately 29% or less. It will attenuate to about 0.5% or less. In addition, if one or both of the optical conductor cables are movable, it is convenient if they can be rotated at the connection point. In the case of such optical conductor cables, it is difficult to make the end faces of each optical conductor core of both optical conductor cables face one-to-one, and when the end faces do not face each other reliably, the transmission efficiency is significantly reduced. descend.

れがあり、あまり効率のよいものではなかつた。 FIG. 1 is an end view of an optical conductor cable to which a connector according to the present invention is applied, and the optical conductor cable has a plurality of cores (a first core having a circular cross-sectional shape).
The cladding at the end of each of the light guides (7 in the case of the figure) is removed to leave only the core part 1, and around one of these light guides there are many (6 in the case of Fig. 1) core parts. are bundled into a concentric hexagonal shape 101 to form the cable end. It is well known that the end face of a light guide cable is constructed by bundling a large number of light guides with a circular cross-sectional shape, but in the past, the cladding layer of the light guides was bundled as is without cutting them, so it was difficult to connect them to the light guide cable. The introduction efficiency of light energy was poor.
In order to eliminate these drawbacks, it is easy to think that it would be possible to remove the cladding layer at the end of the light guide and bundle only the core part, but in that case, it would be possible to simply bundle only the core part. If this is done, a gap will be created between the cores, making it impossible to obtain sufficient light energy introduction efficiency. For example, if the light guide core 1 is arranged as shown in FIG.
A gap is created between the cores 1, 1..., and the total cross-sectional area of the light guide cores 1, 1... is a circle that includes these light guide cores 1, 1... (in other words, the outermost (circle circumscribing the core forming a concentric hexagon)
It is quite small compared to the area of 20 1 , about 78%, so in the worst case, when such a light conductor cable is connected, the light energy transmission efficiency is 56%.
There was a risk that the rate would drop to 12% after two connections, so it was not very efficient.

ことによつて更に改善される。 The present invention has been made in order to solve the above-mentioned drawbacks of the prior art, and as shown in the figure, there is a void formed between the light guide cores 1, 1, . . . A circle 20 1 that is outside and circumscribes the core part that forms the outermost hexagon of the hexagon.
The cladding of the light guide having light guide cores 2, 2..., 3, 3..., etc. having a smaller diameter than the light guide core 1 is cut out and these core parts are placed in the inner gap of the light guide. By increasing the mounting area of the photoconductor core,
In addition to improving the average coupling efficiency, the optical conductor cores 1, 2, 3, etc. are made symmetrical at every rotation angle of 60 degrees with respect to the center point P, and the optical conductor cable configured in this way is connected. The connector can be locked every time it is rotated by 60 degrees, and the coupling efficiency at the locked position is approximately 100%, thereby significantly increasing the coupling efficiency of both optical conductor cables. In the case of Figure 1, if the diameter of light guide core 1 is 1 mm, the diameter of light guide core 2 is approximately 0.352 mm,
The diameter of the light guide core 3 is about 0.17 mm, the diameter of the light guide core 4 is about 0.156 mm, and the diameter of the light guide core 5 is about 0.102 mm.
mm, the diameter of the light guide core 6 is about 0.062 mm, the diameter of the light guide core 7 is about 0.062 mm, and the diameter of the light guide core 2 is about 6 mm.
12 light guide cores 3, 6 light guide cores 4,
Since there are 18 light guide cores 5, 30 light guide cores 6, and 18 light guide cores 7, the total end area of the light guide cores when composed of light guide cores 1 and 2 is circle 2.
The ratio to the area of 0 1 is approximately 86%,
This is a considerable improvement over the case of only the light guide core 1. Below, when calculating in the same way, when the light guide cores are composed of 1, 2, and 3, it is about 89.8%, when the light guide cores are composed of 1 to 4, it is about 91.5%, and when the light guide cores are composed of light guide cores 1 to 5, it is about 91.5%. 93.6% in case of light guide cores 1 to 6, about 94.6% in case of light guide cores 1 to 6, and about 95.4% in case of light guide cores 1 to 7, only light guide cores 1, 1...... This is considerably improved compared to the case of 1, and is further improved by arranging the light guide cores 8, 9, etc.
