Referring to FIG. 1, the two bodies 200 and 300 are preferably made of stainless steel or synthetic resin so as to precisely process the ends so that they can rotate smoothly and prevent corrosion.

At this time, the front end of the body 300 of the one side is formed with a receiving portion 302 to be rotated by inserting a portion of the other end of the body 200 of the other side and the receiving member 302 is embedded with a rotating member 301 Both body (200,300) was to be able to rotate smoothly and safely.

To this end, the rotating member 301 used a bearing or a bush that can ensure a smooth and safe rotational force.

On the other hand, the lens members (210,310) interpolated so as to face each other at the front end of the body (200,300) of the present invention serves to collect and transmit the optical signal, the lens members (210,310) has a high precision for transmission Regardless of the signal transmission direction, an optical lens that can easily condense is used.

The lens members 210 and 310 may be applied in various forms including spherical shape, GRIN type, spherical shape, aspherical shape, columnar shape, linear shape and mixture thereof according to the loss range of the transmission signal.

In the present invention, as shown in Figure 4, the lens member (210, 310) is wrapped (sealed) the front end using a sealing member 211 and the matching material 212, the matching material 212 is a sealing member 211 In order to prevent the light from being refracted by the gap generated between the tip ends of the lens members 210 and 310, the filler is filled in the inside thereof.

In particular, the sealing member 211 is made of a variety of materials that can minimize the friction as well as prevent the discharge of the refractive index matching material 212 to the outside while sliding at the same time the rotation of the body (200,300). Do.

The reason why the refractive index matching material 212 should be filled with the gap generated between the tip ends of the lens members 210 and 310 is that the refractive index of the optical lens is about 1.414, whereas the refractive index of air is about 1, and thus the difference is transmitted by the difference in the refractive index. Since the loss of the signal is obvious, in order to minimize the loss of the transmission signal, the refractive index matching material 212, which is the same or similar to the refractive index of the lens members 210 and 310, is used.

To this end, the refractive index matching material 212 selectively used any one of glycerin, bromobenzene, and bromonaphthalene.

In this case, the refractive index matching material 212 may employ a polymer resin according to a working situation. However, in this case, since polymerization is incomplete, unreacted monomers may exist or bubbles may be generated.

Referring to FIG. 4, a brush 221 is formed at the tip of the power transmission line 220 and a sleeve 321 is installed at the tip of the power transmission line 320 to abut the brush 221. Since the brush 221 and the sleeve 321 are always in contact with each other in the rotation state of the body (200,300) it is possible to supply power smoothly.

Connection sockets 222 and 322 for supplying power transmitted from the outside are formed at the rear ends of the power transmission lines 220 and 320, respectively.

At this time, the brush receiving portion 223 is naturally formed to have a free space so that the brush 221 can move in the front and rear direction by the elastic force of the elastic body 224.

In addition, the optical signal converting members 230 and 330 serve to combine and separate the optical signals transmitted from the outside or transmitted through the lens members 210 and 310 and the optical signals transmitted through the bidirectional all-optical converting members 240 and 340. do.

To this end, the optical signal conversion members 230 and 330 use a wavelength-independent bidirectional optical coupler (WIC) coupler.

In this case, optical cables 233 and 333 may be connected between the optical signal converting members 230 and 330 and the lens members 210 and 310 to transmit optical signals, and optical cables 232 and 332 may be used at rear ends of the optical signal converting members 230 and 330. It is connected to the connection sockets 231 and 331 formed at the rear ends of the bodies 200 and 300 to input and output optical signals.
