Abstract: PROBLEM TO BE SOLVED: To provide an optical connector for optical cable. SOLUTION: An optical connector which terminates an optical cable 10 including a plastic optical fiber 11 enclosed by a protective jacket 12 includes a housing which has an external latch 201 which is to be fixed to an adapter. This latch 201 is constituted as a cantilever having its fixed end and is placed toward the front end of the housing. The connector includes a cable holding structure which is attached to the jacket of the optical cable so that the plastic optical fiber 11 may be connected to a related optical device without using a ferrule. One cable holding structure is made of a metal and includes a guide tube pressed or insert-molded to the rear end of a plastic housing 40.

Abstract: PROBLEM TO BE SOLVED: To provide the integrated receptacle for fitting to a panel which makes a high-density optical mutual connection structure compact. SOLUTION: The receptacle 40 is molded out of a thermoplastic material almost in a rectangular shape and includes at least one cavity 460 which is surrounded with four side walls. The cavity has an opening for receiving an optical connector at its front end and another opening 422 for receiving a cylindrical positioning sleeve 440 at its rear end. A couple of cantilevers 410 are provided on the top surface 415 and another couple of cantilevers are provided on the bottom surface 416. The receptacle 40 has a flange 412 at its rear end and catches a panel edge between the flange 412 and the free ends of the cantilevers in cooperation with the free ends. On the opposite side of each cavity 460, a tab holding shoulder is provided which mutually meshes with the projection of the latching tab 120 of the optical connector.

Abstract: An optical connector Ä20Ü is disclosed for terminating an optical cable Ä10Ü comprising a plastic optical fiber Ä11Ü surrounded by a protective jacket Ä12Ü. The connector Ä20Ü includes a housing Ä21,22Ü having an exterior latch Ä201Ü that secures it to an adapter Ä31Ü. The latch Ä201Ü is constructed as a cantilever with its fixed end positioned toward a front end of the housing Ä22,45Ü. The connector Ä20Ü further includes a cable-holding structure that attaches to the jacket Ä12Ü of the optical cable Ä10Ü in such a manner that the plastic optical fiber Ä11Ü connects to an associated optical device without the use of a ferrule. One cable-holding structure includes a guide tube Ä45Ü that is made from metal and is pressed, or insert molded into the back end of one plastic housing Ä40Ü. A portion of the guide tube Ä45Ü protrudes from the back end of the housing and is crimped onto the optical cable Ä10Ü. Here, the optical cable Ä10Ü is immovably attached to the housing. Another cable-holding structure includes an extender cap Ä21Ü, a spring Ä60Ü, and a guide tube Ä15Ü having an enlarged diameter at one end Ä16Ü. The spring Ä60Ü surrounds the tube Ä15Ü and presses against its enlarged end. The spring Ä60Ü also presses against an interior surface of the extender cap Ä21Ü, which inserts into the back end of another plastic housing Ä22Ü. Here, the optical cable is movably attached to the housing.

Abstract: A unipartite (one-piece) jack receptacle 40 for mounting in a panel 200 provides a compact structure for high density optical interconnections. The receptacle is molded from thermoplastic materiel into a generally rectangular shape and includes at least one cavity 460 surrounded by four sidewalls. The cavity includes one opening in its front end for receiving an optical connector 10 and another opening 422 in its back end for receiving a cylindrical alignment sleeve 440. Each opening extends into the cavity. One pair of panel-locking members (cantilevers) 410 is mounted on the top side 415 of the receptacle and another pair of cantilevers is mounted on its bottom side 416. Each cantilever includes a free-end portion that deflects into the cavity. The receptacle further includes a flange 412 on its back end that cooperates with a smooth tapered wall 411 on the free-end portion of the cantilever to capture a panel edge therebetween in a self-tightening fit. Molded into opposite sidewalls of each cavity are tab-retaining shoulders for interlocking with projections 121 on a latching tab 120 of the optical connector. A pair of identical jack receptacles 40 are joined together, back to back, to form an adapter 400. Cylindrical pins 423 and holes 421 are located on the back surface 420 of each receptacle to facilitate assembly. The pins have slightly larger diameters than the holes so that the receptacles can be press-fit together without the use of adhesives or other bonding techniques.
