Optical fiber cord fixing component

#1. Field of the Invention

#The present invention relates to a fixing component for fixing an optical fiber cord to an optical connector.

#2. Description of Related Art

#FIG. 1 is a perspective view showing a condition in which an optical fiber cord is fixed to an optical connector by an optical fiber cord fixing component according to the present invention;

#FIGS. 2A to 2D are drawings showing the optical fiber cord fixing component according to the present invention, in which FIG. 2A is a front view, FIG. 2B is a plan view, FIG. 2C is a side view, and FIG. 2D is a rear view;

#FIG. 3A is a longitudinal sectional view showing a condition in which the optical fiber cord is connected to the optical connector by the optical fiber cord fixing component according to the present invention, and FIG. 3B is a cross sectional view of the same condition;

#There will be detailed below a first embodiment of an optical fiber cord fixing component according to the present invention, with reference to FIG. 1 and FIG. 3B. A fixing component 10 according to the present invention is for fixing, in a press-fitting manner, an optical fiber cord 2 to an optical connector 1 (connector housing) by deforming, in a compressing manner, as generally shown in FIG. 1. On a distal end of optical fiber in the optical fiber cord 2 press-fitted to be fixed to the optical connector 1, there is fitted a ferrule 12.

#The fixing component 10 according to the present invention is integrally formed with a tension member fixing portion 4 for fixing, in a press-fitting manner, a tension member 3 of the optical fiber cord 2 to the optical connector 2, as shown in FIG. 3A, and a sheath fixing portion 6 for fixing, in a press-fitting manner, a sheath 5 of the optical fiber cord 2 to the connector 1, as shown in FIG. 3B.

#As shown in FIGS. 2A to 2D and FIGS. 3A and 3B, the tension member fixing portion 4 is a tube of a substantially elliptic (or substantially oval) form in section, and the inside is so dimensioned that it can be put on an outside of the tension member 3 of the optical fiber cord 2 which is put on an outer peripheral surface of a large diameter part 16 of the optical connector 1 (connector housing) that is stepped. As shown in FIG. 2B and FIG. 2C, in the tension member fixing portion 4, an end part 18 at the sheath fixing portion 6 side is reduced to be tapered toward the sheath fixing portion 6.
