Benefits of technology

The present invention provides an optical connector that can protect a coated fiber from damage during work, and an improved assembling method for the optical connector. The optical connector includes a mechanical splice that holds a ferrule with a short fiber, and a jacket fixture that fixes the cable jacket covering the coated fiber. The mechanical splice is housed in a movable state in the outer housing, and a spring is used to bias the mechanical splice towards the tip side. This prevents the coated fiber from being bent or broken during work. The optical connector is easy to assemble and reduces production costs.

Problems solved by technology

In the above-described optical connector, the coated fiber is led out from the rear end face of the mechanical splice and the coated fiber can be subject to an excessive force such as a bending force from the outside during a work, which could result in causing trouble of breakage of the fiber or the like.
However, works such as attachment of the boot and the protecting tube are cumbersome and take some time.

first embodiment

[0080]FIG. 1 is a perspective view of a male optical connector according to the first embodiment of the present invention, FIG. 2 a perspective view of the lower side of the male optical connector (before insertion of a clip) shown in FIG. 1, FIGS. 3 to 5 views showing the male optical connector, FIG. 6 a perspective view of a coupling member shown in FIG. 5, FIG. 7 a perspective view of a spring push shown in FIG. 5, FIGS. 8 and 9 views showing a jacket holder shown in FIG. 5, and FIG. 18 a transverse sectional view of an indoor cable. In the description hereinafter, terms indicating directions will be based on the state shown in FIG. 1. Specifically, a direction in which a jacket fixture is located relative to an outer housing is defined as “back.”

[0081]The optical connector of the present embodiment is an in-situ assembling type single-fiber optical connector having a mechanical splice structure and being suitable for assembly at a job site, and is used for connection of an optic...

second embodiment

[0159]Next, a male optical connector according to the second embodiment of the present invention will be described with reference to FIGS. 19 to 23. FIG. 19 is a perspective view of the male optical connector in a closed lid state (before attachment of an optical cable), and FIGS. 20 to 23 are views showing the male optical connector of FIG. 19 in an open lid state. This male optical connector 31 of the second embodiment is different from the male optical connector 1 of the first embodiment in that the jacket fixture 4 shown in FIG. 1 is replaced by a jacket fixture 32 shown in FIGS. 19-23 and in that the jacket holder 14 shown in FIG. 5 is replaced with a jacket holder 37 shown in FIG. 21, without the clip 15 shown in FIG. 5.

[0160]Specifically, as shown in FIGS. 19-23, the jacket fixture 32 is provided with a jacket fixture body 33 coupled to the mechanical splice through a coupling member having much the same function as in the first embodiment, a first movable portion 35 and a se...

Abstract

An optical connector according to an embodiment of the present invention comprises (a) a ferrule incorporating a short fiber; (b) a mechanical splice having a holding part and a fixing part, and adapted so that the fixing part mechanically fixes the short fiber extending from the ferrule held by the holding part, and an optical fiber in an optical cable to butt the short fiber; (c) an outer housing having a housing part in which the mechanical splice is located, and a pair of flexible arms located on both sides of the housing part, the pair of arms each being provided with a locking claw at a tip; and (d) a jacket fixture for fixing a cable jacket, the jacket fixture being coupled to the mechanical splice so that the cable jacket is inserted therein.

Description

RELATED APPLICATIONS[0001]This application is a Divisional of U.S. patent application Ser. No. 11 / 660,539, filed on Aug. 30, 2007, which is a U.S. National Phase under 35 U.S.C. §371 of International Application No. PCT / JP2005 / 015638, filed on Aug. 29, 2005, which in turn claims the benefit of Japanese Application No. 2004-259380, filed on Sep. 7, 2004, the disclosures of which Applications are incorporated by reference herein.TECHNICAL FIELD[0002]The present invention relates to an optical connector to be suitably connected to an optical cable of a tight structure, and to an assembling method of the optical connector.BACKGROUND ART[0003]For example, an optical cable such as a drop cable or an indoor cable is a cable in which a coated optical fiber and tension members are covered by a jacket (sheath), and has a so-called tight structure in which the coated optical fiber and tension members are attached tightly to the cable jacket.[0004]A conventional optical connector to be connecte...
