Filed:

Jun 16, 1989

Appl. No.:

7/369411

Inventors:

Norbert L. Moulin - Placentia CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

B24B 100

US Classification:

51281R

Abstract:

A grinding and polishing machine (11) which includes a grinding section (15), a polishing section (17), a fixture (19) and a fixture bearing assembly (21). Fiber optic termini (169) are retained in the fixture (19) so that distal ends (185) of optical fibers (177) and end faces (181) can be ground by a grinding abrasive (80) and polished by a polishing abrasive (91). The distal ends (185) and the end faces (181) prevent contact between the fixture (19) and the grinding abrasive (80) and the polishing abrasive (91).

Abstract:

A lens type connector (13) comprising a connector body (31) having a passage (47) extending through it in an axial direction and a bushing (35) fixedly retained in the passage (47) of the connector body (31) and having a bushing passage (59) extending axially completely through the bushing. The bushing (35) has a radially inwardly projecting shoulder (61) in the bushing passage (59). A graded index rod (33) is movable axially in the passages (47, 59) so that an end face (77) of the graded index rod (33) can be urged against the shoulder (61) to at least assist in positioning and retaining the graded index rod (33) in the passages (47, 59).

Appl. No.:

5/723357

Inventors:

Norbert L. Moulin - Placentia CA

Assignee:

Hughes Aircraft Company - Culver City CA

International Classification:

H01R 1340

US Classification:

339217S

Abstract:

A crimp type contact having a wire wrap post secured thereto is prevented from rotating within an insulation block when a conductor is wrapped around the post by a small stamped sheet metal spur attached to the contact which is so configured that, when the contact is installed into its cavity in the insulation body, the spur bites into the walls of the cavity.

International Classification:

B25B 2714

US Classification:

29271

Abstract:

A hand held tool 211 for inserting or removing a fiber optic contact alignment tube segment 47 into a fiber optic connector 13. The tool includes a hollow shaft 215 anchored in a knob 213 and extending coaxially through a cylindrical chamber in the knob. A core 225 having an axial bore extending therethrough resides rotatably in the chamber, with the post acting as its shaft. A shroud 235 extends from the core 225 and has an arcuate slot 237 near its tip. When an alignment tube segment 47 is inserted in the hollow post 221 and the shaft 215 is turned 180. degree. relative to the core 225, an enlarged portion 48-2 of the base of the tube segment 47 enters into and is captured by the slot 237. The tool may then be inserted into a connector whose front end mirrors the front end of the tool 211. When the knob 213 is again turned 180. degree.

Appl. No.:

5/781084

Inventors:

Norbert L. Moulin - Placentia CA

Assignee:

Hughes Aircraft Company - Culver City CA

International Classification:

H01R 1352

US Classification:

339 94R

Abstract:

Electrical pin and socket contacts, contained within connectors and interconnectable with one another by mating connection of the connectors, are sealed from the environment external to the interior of the connectors and the connection therebetween regardless of changing pressure conditions. Individual pressure-sensitive wire seals are utilized for each contact at the rear of the connectors and a two sided pressure-sensitive interface seal is utilized for sealing between two mating connectors. The pressure-sensitive wire seal at the rear of each connector includes a tubular portion jacketed in sealing contact on the conductor insulation, a cup-shaped flange opening toward the rear of the connector, a wiper land inwardly disposed of the cup-shaped land, and an interlocking engagement between the seal and the wire-receiving end of the contact. The pressure-sensitive interface seal sealingly engages each pin end of the pin contact and has a pair of cup-shaped seals facing each other and facing the front faces of the two connectors when each pin contact in one connector engages the socket contact of the other connector.

Appl. No.:

7/091932

Inventors:

Norbert L. Moulin - Placentia CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

G02B 638

US Classification:

350 9621

Abstract:

A fiber optic terminus (11) comprising a body (13) having a passage (15) therein which opens at an outer surface. The passage (15) can receive an optical fiber (19), and the fiber is guided into position by a fiber guide (17). A temperature-activated adhesive (21) is carried by the body (13), and the adhesive (21) is flowable when its temperature is raised to a predetermined level. A force-applying system, including a plunger (23) and a spring (25), applies a compressive force to the adhesive (21). Accordingly, when the temperature of the adhesive (21) is raised to the predetermined level, the adhesive (21) flows under the influence of the compressive force and adheres the optical fiber (19) in the passage (15).

International Classification:

H01R 1362

US Classification:

439321

Abstract:

A coupling mechanism (11) comprising a receptacle (13) having an open cavity (31) therein, a plug (15) receivable in the cavity (31), and a rotatable coupling member (17) drivingly coupled to the plug (15) and coupling the plug (15) to the receptacle (13). A locking member (19) is mounted on the coupling member (17) for rotation with the coupling member (17) and for translation relative to the coupling member (17). A spring (21) acts between the locking member (19) and the coupling member (17) and urges the locking member (19) to translate with the coupling member (17). Translation of the locking member (19) is limited so that the spring (21) is compressed to store energy. A cam track (33) and a cam follower (105) have interlocking members which are driven into interlocking relationship by the stored energy in the spring (21) when the locking member (19) and the receptacle (13 ) are in a predetermined angular position relative to each other. The interlocking members retain the locking member (19) rotation relative to the receptacle (13).
