Embodiment 1
[0073] figure 1 It is a perspective view showing the appearance of the optical connector 1 according to Embodiment 1 of the present invention together with opening and closing members, figure 2 yes figure 1 side view of the optical connector 1, image 3 It is a longitudinal sectional view of the optical connector 1 .
[0074] This optical connector 1 is provided with: ferrule 3, and it is provided with built-in optical fiber (cladding is removed the bare optical fiber) 2, and ferrule 3 is implemented end face grinding; The opposite side is extended. The built-in optical fiber 2 is butt-connected to the bare optical fiber 10 a inserted into the optical fiber 10 .
[0075] Both the built-in optical fiber 2 and the bare optical fiber 10a inserted into the optical fiber are silica optical fibers with a diameter of 125 μm.
[0076] The connection mechanism 4 consists of a base body 6 formed with a positioning groove 5 continuous with the fiber hole 3a of the ferrule 3, a cove...
Embodiment 2
[0104] Below, combine Figure 8A ~ Figure 10B , the optical connector 1 according to the second embodiment will be described. The description of the same parts as in Example 1 will be omitted, and the description will focus on different parts.
[0105] The present embodiment 2 has the above-mentioned and Figure 1 to Figure 5 The structure is the same, and its description is omitted here. In embodiment 2 of the present invention, such as Figure 8A as well as Figure 8B As shown in the enlarged figure, the end face 2a of the rear end side of the built-in optical fiber 2 that abuts with the inserted optical fiber 10 is formed into an inclined end face 2a by cutting processing, and the above-mentioned inclined end face 2a of the built-in optical fiber 2 is subjected to discharge treatment using a thermal splicer, thereby The edge rounding of the inclined end face 2a is mainly performed. The rounded peripheral edge is indicated by reference numeral 2b. Likewise, the inserti...
Embodiment 3
[0126] Below, combine Figure 11A ~ Figure 12C , the optical connector according to the third embodiment will be described. The description of the same parts as in Embodiment 1 will be omitted, and the description will focus on different parts.
[0127] In Embodiment 1, although the refractive index matching agent is filled between the end faces of the two optical fibers, in this Embodiment 3, as will be described later, there are cases where it is necessary to fill the refractive index matching agent between the end faces of the two optical fibers, and There is no need to fill the refractive index matching agent between the end faces of the two optical fibers.
[0128] The present embodiment 3 has the above-mentioned and Figure 1 to Figure 5 The structure is the same, and the explanation is omitted here. In embodiment 3 of the present invention, as Figure 11A as well as Figure 11B As shown in the enlarged figure, the end face 2a on the rear end side of the built-in op...
