Embodiment Construction

[0027] Hereinafter, examples of the present invention will be described.

[0028] Figures 4A-4C Showing the appearance of an embodiment of the L-angle optical connector of the present invention, Figure 5A , 5B Indicates its cross-sectional structure. In this example, the L-angle optical connector is composed of a housing 30 , an L-angle member 40 , a ferrule 50 , a coil spring 60 , a sleeve 70 , a riveting ring 80 , a screw 90 and a protective cover 100 . In addition, in Figures 4A-4C and Figure 5A , 5B Among them, 200 represents the optical cable.

[0029] First, the configuration of each unit will be described.

[0030] Housing 30 such as Figures 6A-6F As shown, it is composed of a cylindrical portion 31 , a square flange portion 32 provided at the rear end of the cylindrical portion 31 , and an extension portion 33 formed to extend rearward from the flange portion 32 . The four corners of the flange part 32 are chamfered, and the holes 32a for mounting and fix...

Abstract

An L-angle type optical connector for bending and wiring an optical fiber in a right-angle direction, wherein the L-angle member for accommodating the bent portion of the optical fiber in the right-angle direction has a length along the inner side of the bend portion throughout the entire length of the L-angle member The notch is formed with a protrusion protruding from the inner side surface of the L corner member sandwiching the notch. Since the member for accommodating the bent portion of the optical fiber in the right-angle direction is composed of one member, the number of parts and the number of assembly steps can be reduced compared to the conventional case of two-member configuration.

Description

technical field [0001] The present invention relates to an L-angle optical connector for bending and wiring optical fibers in a right-angle direction. Background technique [0002] Figure 1A ~ 1C As a conventional example of such an L-angle optical connector, the configuration described in Patent Document 1 is shown. [0003] In this example, the optical connector has: the optical fiber core wire 11 is inserted and fixed and the flange 12 is pressed into the fixed ferrule 13 at the rear end; The stop ring 15 that supports the rear end of the spring 14 that is pressed forward; the latch frame 16 that covers these parts; The riveting matrix 18 inside the opening side of the other end; the riveting base 19 that fixes the Kevlar fiber (ケブラ) 10a as the expansion force line of the optical cable 10 to the riveting base 18; the Kevlar fiber (ケブラ) covering the optical cable 10 10a outer synthetic resin sheath 10b is fixed on the riveting ring 21 on the riveting seat 19; the protec...
