An optical connector includes a receptacle body 40 having an engage hole 46 formed in a peripheral wall 45 of a chamber 44, a pigtail body 50 having a base body 51 contained in the chamber 44 and a locking protrusion 56 engaged in the engage hole 46 to attach the pigtail body 50, and a ferrule assembly 60 being inserted in a container 53 in the base body 51 so that the ferrule 62 is positioned in a receptacle cylinder 52, and a spring 70 inserted through an opening 54 in the base body 51 and pressing the ferrule 62 forward, wherein a stopper 73 is formed in the spring 70 as an integral part of the spring 70. A locking part 73b included in the stopper 73 is positioned in a recess 63 in the ferrule 62.

The present invention relates to an optical connector used in an in-vehicle LAN, for example, and, in particular, to an optical connector holding a terminal of an optical fiber cable.
FIG. 1 shows a configuration of an optical connector described in Japanese Patent Application Laid Open No. 2002-131584 (filed on May 9, 2002, hereinafter referred to as Document 1), which is one example of a conventional optical connector of this type. In FIG. 1, reference numeral 11 denotes a housing, 12 denotes a stopper, and 13 denotes an optical fiber cord. The optical fiber cord 13 in this example has a first cladding 13b around the perimeter of an optical fiber 13a and a second cladding 13c around the perimeter of the first cladding 13b.
A cord hole 14 for containing the optical fiber cord 13 is formed in the housing 11. An opening 15 is formed on one side of the cord hole 14 for allowing the cord hole 14 to communicate with the exterior. A ferrule 16 holding the optical fiber 13a is formed at an end of the housing 11.
FIG. 1 is a cross-sectional view showing an example of a conventional configuration of an optical connector;
FIG. 2 is a partial cross-sectional view showing another example of a conventional configuration of an optical connector;
FIG. 3A is a plan view showing an embodiment of an optical connector according to the present invention;
An embodiment of the present invention will be described below.
FIG. 3A shows an exterior view of an optical connector according to the present invention. FIGS. 3B, 4, and 5A show a cross section structure of the optical connector. FIG. 6 shows the optical connector disassembled into components. In the example, the optical connector includes a receptacle body 40, pigtail body 50, a pair of ferrule assemblies 60, and a spring 70. FIG. 7 shows the spring 70 enlarged.
A configuration of each of the components will be described first.
