1527014 Optical fibre connectors FELTEN & GUILLEAUME CARLSWERK AG 17 May 1976 [25 June 1975] 20312/76 Heading G2J [ Also in Division B5] A connector for optically conductive filaments 5 is made by casting the two halves 6, 7 of the connector as one body 1 with a filament (3) Fig. 1 (not shown) and two parallel guide pins (2) embedded in the body, removing the filament and guide pins, dividing the body in two perpendicular to the axes of the ducts formed through the body, and securing guide pins 9 into one half 6 and optical filaments 5 into both halves 6, 7. The filament (3) used to form the ducts for the optical filaments 5 may be an optical or non-optical filament or a steel wire coated with grease then a layer of evaporated metal to ensure release from the body. The halves 6, 7 of an epoxy resin connector body are secured e.g. in a floating manner by silicone rubber in two interfitting sleeves 10, 16. A nut 18 is screwed on to the enlarged end portion of the sleeve 10 to clamp the assembly. Locating lugs 20 on the sleeve 10 engage corresponding grooves 21 in a rim 17 of the sleeve 16. Abutment of the rim 17 with the end of the other sleeve 10 and the use of two rubber O-rings 24 prevent overtightening of the assembly. Greater numbers of locating pins 9 and optical filaments 5 may be used. |
