Abstract: PROBLEM TO BE SOLVED: To provide an improved shape memory material for an optical fiber connector application. SOLUTION: A connector for joining an optical element, especially an optical fiber is disclosed. The connector is a sleeve made of a simple shaped memory polymer(SSMP) into which the optical fiber is inserted, and the sleeve is heated to collapse the sleeve around the optical fiber. The SSMP material is not crosslinked and can be manufactured by a variety of techniques including extrusion. Various methods for forming the bore of the connector and expanding the size of the bore from the memory state to the metastable state are disclosed.

Abstract: PROBLEM TO BE SOLVED: To provide an optical connector containing a material having satisfactory side loading ability, flexibility, chemical resistance and satisfactory environmental performance over a wide range of temperature and humidity and having desired knitting characteristics and relatively low sensitivity to molding parameters. SOLUTION: This optical connector 1 having a housing assembly 10 containing polyphenyl sulfone(PPSU) is provided. The PPSU has the several characteristics suitable for use together with the optical connector including satisfactory flexibility, low sensitivity to the molding parameters, satisfactory environment characteristics and the adaptability to the anaerobic adhesive frequently used for mounting an optical fiber to a ferrule 16. The connector has a ferrule assembly 11 and insertion part 24 which are to be housed in a one-piece housing. When the insertion part is inserted into the first end of the housing, a keying mechanism of the insertion part meshes with the keying mechanism of the housing and fixes the insertion part to the fixed position in the housing.

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: 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.

Abstract: The present invention provides an optical connector having a housing assembly comprised of polyphenylsulfone (PPSU). PPSU has several characteristics that make it suitable for use with optical connectors including good flexibility, low sensitivity to molding parameters, good environmental properties, and compatibility with anaerobic adhesives, which are often used to attach the optical fiber to the ferrule in private networks. The connector preferably comprises a one-piece housing (10), which enhances the side-loading characteristics of the connector. The connector preferably comprises a ferrule assembly (11) and an insert (24) that are housed within the one-piece housing. The insert has a keying mechanism (25) formed thereon that is adapted to mate with a keying mechanism (32) formed in the housing. When the insert is inserted into the first end of the housing, the keying mechanism of the insert interlocks with the keying mechanism of the housing to lock the insert into place within the housing.
