Precise to transmit the optical signal. The headgear structure 11 includes a sleeve 14 and a set of rings 15 coaxially disposed within the sleeve and at the bottom end, and extending a portion of the length of the fiber 13 into the ferrule 15. The bottom surface of the ferrule 15 is provided with a slanting surface 16 to prevent the reflected light source from entering the illuminating 7L member, so that the illuminating element is disturbed by noise. As shown in Figure ', in terms of geometric optics theory, the beam exit angle is calculated as M419934, where nsm(M)=SIN(w + w), n: fiber refractive index, θ1: the angle of the fiber at the end face of the ferrule , Θ 2 · · The fiber axis and the central angle of the light exit direction. The ferrule 15 is placed in the sleeve in an upright manner by the δH formula and the theory that the light is incident on the optical fiber and the light is emitted from the optical fiber (that is, the light incident angle and the light exit angle 0 2) are the same as the axial direction. In the tube 14, the optical signal incident direction of the light-emitting element 丨7 is in line with the optical fiber 13 without being emitted in the same axial direction as the outgoing light of the optical fiber 13, thereby causing loss of the incident optical signal, and this deficiency needs to be remedied. [New content] The main purpose of this creation is to provide a fiber optic connector that can improve the coupling efficiency without changing the incident direction of the light-emitting element. In order to achieve the above objective, the fiber connector of the present invention comprises a fiber optic transmission line having an optical center, a coating layer covering the outside of the optical core, and a buffer layer covering the outside of the coating layer and exposing part of the optical core to the optical fiber. a transmission line end; and a hood structure having a sleeve g and a ring having a central hole therein for receiving the fiber transmission line; and - a slanting hole leading to the center hole for receiving the ferrule The sleeve H can be used to receive a part of the optical core. The ferrule is disposed in the slanting manner in a tilted manner due to the limitation of the slanting hole, so that the illuminating signal can be used for the direction of the positive light and the illuminating signal of the illuminating element. The incident axial direction causes the illuminating signal to reduce the loss at the time of incidence to improve the coupling efficiency. In order to further understand the features and technical contents of this creation, please refer to the following detailed description and drawings regarding this creation. However, the drawings are for reference only and refer to M419934 • ·, not for any use of this creation. Limiter. [Embodiment] Referring to FIG. 2 and FIG. 3, the optical fiber connector 2g of the present invention includes an optical fiber transmission line 21 and a headgear structure 30. The optical fiber transmission line 21 has a light core 22, a coating layer 23 covering the outside of the optical core 22, and a cladding layer covering the second layer of the coating layer. The buffer layer is substantially 'the optical fiber transmission line 21 is mounted on the head cover structure 3'. It is necessary to remove a portion of the coating layer 23 and the buffer layer 24 from the free end thereof so that the partial optical core 22 is exposed at the end of the optical fiber transmission line 21. The hood structure 30 has a sleeve 31 and a set of rings 4, and the inner L of the sleeve has a diameter 32 which is sized to receive the optical fiber transmission line η; and a slanted hole 33 leads to the center A bore 32, diametrically sized, is adapted to receive the ferrule 40 and to provide the ferrule 4 in an oblique manner in the sleeve 31. The ferrule 40 has a through hole 41 diametrically sized to receive a portion of the optical core 22 of the optical fiber transmission line 21, the ferrule 4A including a first end u and a second end 43 and a first end 42 In the opposite direction of the arrangement, the first end 42 has a guide groove 44' for allowing the optical core 22 to be quickly inserted into the through hole 41. The second ends are - beveled to prevent reflected light from directly incident on the light-emitting elements, causing the light-emitting elements to be disturbed by noise. Since the sleeve 40 is disposed in the sleeve f 31 in an inclined manner when it is restricted by the inclined hole 33 in Annon, the direction of the beam is the same as the direction of the beam of light to satisfy the beam exit angle. The calculation formula, therefore, the light signal emitted by the light-emitting element (9) 5 M419934 can be accumulated in a large amount to the optical anger η of the optical fiber transmission line 21, thereby reducing the shank loss 'to greatly improve the coupling efficiency, as shown in FIG. 4, The ferrule 40 is inclined at an angle of 2 ,, and the light exiting direction of the ferrule 4 桥 is the same as the incident direction of the illuminating signal of the illuminating element 50, and the optimal coupling efficiency can be obtained.
