摘要： An optical connector that is capable of ensuring excellent waterproofing using a simple structure is provided. The optical connector comprises a connector plug and socket. Each of the plug and socket have a housing, which has a cable-guiding part and a cable-retaining part; a ferrule disposed within the housing and to hold a leading-end part of an optical fiber exposed from a sheath of an optical cable; and a seal member disposed between the cable-guiding part and the cable-retaining part to seal the cable-guiding part.

摘要： To provide an optical connector that enables the reduction in the number of parts and can be easily attached to an optical cable, a concave portion 18 for a ferrule is formed in a plug housing 6, and a ferrule 3 is inserted from the side of a collar portion 10 into the concave portion 18 for a ferrule. A hook portion 28 for a ferrule is provided in a protruding condition inside the plug housing 6. The collar portion 10 is guided by the hook portion 28 for a ferrule, which has been elastically deformed, and moves toward a bottom surface 26 of the concave portion 18 for a ferrule. Where the collar portion 10 reaches a space between the bottom surface 26 and the hook portion 28 for a ferrule, the hook portion 28 for a ferrule is elastically restored. Therefore, even if the collar portion 10 tries to move toward an opening 24 of the concave portion 18 for a ferrule, the collar portion is locked by the hook portion 28 for a ferrule and the movement is inhibited. Thus, in the plug-type optical connector 1, the ferrule 3 can be positioned by inserting into the plug housing 6 and moving.

摘要： Operation efficiency can be dramatically improved and a smaller configuration can be obtained by simplifying the optical connection. An optical module has an electrical connector to connect a device; an optical element unit being electrically connected to the electrical connector and provided with optical elements to convert electrical signals and optical signals and emitting or receiving light; an optical ferrule, having a plurality of optical fiber insertion holes, to hold optical fibers inserted into the plurality of optical fiber insertion holes so as to allow the fibers to be optically connected to the optical element; and an optical cable inlet to introduce an end part of an optical cable provided with the optical fibers. The cable unit with an optical module has an optical cable that includes a plurality of optical fibers and an optical module provided at two ends of the optical cable.
