Description of the invention (1) Field of the invention (please read the back of the page first; note the matters before filling out this page) The present invention relates to an optical fiber connector used to connect audiovisual devices to each other for optical communication. BACKGROUND OF THE INVENTION Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economics Various optical fiber connectors have been proposed and put into practical use. FIG. 18 shows a conventional plastic optical fiber connector 601. This connector is composed of an optical cable 602, and input and output plugs 603 and 604 are respectively mounted to the input and output ends 602a and 602b of the optical cable 602. Plastic optical fiber connector 601 is used to connect electronic devices 701 and 703 by inserting input plug 603 into input jack 702 of electronic device 701, and by inserting output plug 604 into output jack 704 of electronic device 703 in. As shown in Figs. 19 and 20, the optical fiber cable 602 is composed of a single-fiber core 611 and a covering layer 61 2 covering the outside of one of the single-fiber cores 611. The single fiber core 6 11 is made of plastic and functions as a signal transmission medium. The outer peripheral portion of the single fiber core 6 1 1 is covered with a cladding 613. In other words, the cladding 613 is provided between the single-fiber core 61 1 and the cover layer 612. The cover layer 612 is composed of a plastic with better durability in order to protect the single fiber core 6 1 1 and the cladding 6 1 3. In order to connect the electronic devices 701 and 702 through the optical fiber connector 601, the ends of the optical cable 602 are set to be straight, and the plugs 603 and 604 are inserted into the jacks 702 and 702 of the input and output sides of the electronic devices 701 and 703, respectively. 704. SUMMARY OF THE INVENTION However, the above-mentioned plastic optical fiber connector 60 1 has the following problems: -4- The paper size is applicable to the national standard (CNS) A4 specification (210 X 297 mm) 457744 Α7 B7 V. Description of the invention (2) Since the allowable bending radius R of the optical cable 602 is large (approximately 20 mm), it is difficult to use a so-called bent plug, which is used by bending the input and output ends of the optical cable 602 vertically. Therefore, a straight plug must be used when such an optical cable 602 is used. Even when a straight plug is used, the allowable bending radius R of the optical cable 602 is still large, for example, about 20 mm. Therefore, a considerable arrangement space S must be provided as shown in FIG. 21 to ensure the allowable bending radius R of the optical fiber connector 60. This limitation relates to the degree of freedom of wiring of the optical cable 602. The inventors of the present invention have found that the allowable radius of an optical cable using a multi-fiber core is smaller than that of an optical cable using a single-fiber core. Based on the results, the present invention has achieved that the optical fiber connector according to the present invention solves a conventional problem by using a multi-fiber core M optical fiber. The form of the present invention belongs to an optical fiber connector. The connector includes an optical cable using a multi-fiber core composed of a plurality of plastic fibers, and a pair of plugs are installed at both ends of the optical cable. Cooperative printed with this configuration, it is possible to use fiber optic connectors where the fiber is bent at a desired angle while reducing its allowable bending radius to a smaller radius.

Description of the invention (9) {Please read the precautions on the back before filling in this page) Change as shown in Figures 8 and 9 "That is, the plug body 5 can be composed of a fixing part 5 丨 and a The rotatable portion 53 is movable on the shaft 52 with respect to the fixed portion 51 and can be locked at a predetermined rotation angle. This allows the input and output ends of the fiber optic cable 2 to be bent at a desired angle, such as 0, 45, 90, 135, or 180 degrees, as shown in FIG. When the optical fiber cable 2 using the multi-fiber core 11 is bent at 45 °, 90 °, 135 °, and 180 ° to form a 3R bending curve, the amount of light attenuation at the individual bending angles is compared to that of a straight line condition. The attenuation is better, as shown in Figure 11 and Table 1. The graphs in Figure 11 and Table 1 are very clear. Even in the case of a bending angle of 35 degrees, the amount of light attenuation is very small and can be ignored in practical use. Compared with the results of the present invention, when a conventional optical fiber cable 602 using a single fiber core 611 is bent at a bending angle of 45 degrees, 90 degrees, 135 degrees, and 180 degrees to form a 3R bending curve, the individual bending angles are The amount of light attenuation becomes larger as shown in Fig. 11 and Table 1. For example, it is known that the light attenuation of a 45 degree bend angle of 6 0 2 is larger than the light attenuation amount of the 180 degree bend ft angle of the optical fiber cable 2 using the multi-fiber core 11. This clearly proves the superior performance of the optical cable 2 according to the present invention. .
