Abstract:
1. An optical connector kit, comprising: a ferrule with an optical fiber comprising a short length optical fiber which has been fixed to the ferrule in advance, in which the ferrule is subjected to polishing treatment at the terminal surface thereof; a plurality of passing parts which are passed through another optical fiber before the rear end of said short length optical fiber and the front end of said another optical fiber are subjected to fusion splice each other; and a containing case for receiving all connector parts constructing an optical connector including said ferrule with the optical fiber and said passing parts, wherein said containing case can hold one part of said connector parts while in the condition where the parts for fusion splice including said ferrule with the optical fiber and said passing parts can be taken out of said case, wherein said containing case has an upper and a lower housings, in which said both housings are configured such that they can be opened and closed, wherein said upper housing is configured such that its different states including at least a partial open state where said upper housing opens a receiving region of said parts for fusion splice of said lower housing and a full-open state where said upper housing opens all region of said lower housing, or two-step open states, can be switched, wherein said containing case is comprised by said lower housing having a bottom surface that is raised by the peripheral side wall of said lower housing and said upper housing having a lid surface that is raised by the peripheral side wall of said upper housing, in which both lower and upper housings are coupled with each other so as to be opened and closed, wherein said lower housing including a flange around the lower periphery of said side wall; and said upper housing including a flange around the lower periphery of said side wall, wherein when said containing case is closed so as to the lower surface of said flange of said upper housing is overlapped with the upper surface of said flange of said lower housing, said side wall of said lower housing and said side wall of said upper housing are tightly contacted with each other to maintain said containing case closed, wherein said containing case includes a first region for receiving said parts for fusion splice at a side apart from the coupling portion of said lower and upper housings and a second region for receiving said other parts of said connector parts at a side closed to said coupling portion, wherein said containing case includes a lower engagement part and an upper engagement part for engaging said second regions of said lower housing and said upper housing with each other, wherein said lower and upper engagement parts are in the engagement state thereof while said containing case is closed as well as said engagement state is still maintained when said upper housing is opened to said partial open state, while the engagement of said engagement state is released when said upper housing is opened to said full-open state, thereby providing said full-open state.
