Abstract

Optical connecting means for effecting disconnectable optical connections between multiplicities of optical fibres comprises a two-part mechanical connector and a plurality of two-part optical fibre connectors mounted in the body parts, of the mechanical connector. One body part of each optical fibre connector is slidably mounted in and with respect to the body part of the mechanical connector with their axes parallel to one another and is urged by a spring housed in the body part in a rectilinear direction towards the mating end of the body part. One body part of each optical fibre connector is fixedly secured in and with respect to the body part of the mechanical connector with their axes parallel to one another. Preferably, the body parts of the optical fibre connectors in each body part of the mechanical connector 1 are mounted one above another.

Claims

1. Means for effecting disconnectable optical connections between multiplicities of optical guides, which optical connecting means comprises a mechanical connector comprising two separately formed body parts adapted to make a disconnectable plug and socket connection the one with the other and a plurality of optical fibre connectors each comprising at least two separately formed mating body parts, each of which mating body parts has at least one substantially flat end face with which end faces of a plurality of optical fibres secured in said body part are substantially co-planar, at least one body part of each of the plurality of optical fibre connectors being slidably mounted in and with respect to one body part of the mechanical connector with its axis substantially parallel to the axis of said body part of the mechanical connector and with each of its optical fibres adapted to be optically connected to one of a multiplicity of optical guides and being urged by resilient means housed in said body part of the mechanical connector in a rectilinear direction substantially parallel to said axes towards the mating end of said body part of the mechanical connector.

13. Optical connecting means as claimed in claim 1, wherein one body part of the mechanical connector effectively constitutes a socket into which the other body part, constituting a plug, will engage when a plug and socket connection between the two body parts is effected.

14. Optical connecting means as claimed in claim 13, wherein one of the body parts of the mechanical connector has at least one keyway within which a portion of the other body part of the mechanical connector will slidably engage.

15. Optical connecting means as claimed in claim 13, wherein the body parts of the mechanical connector are adapted to effect a releasable snap-fit the one with the other.

16. Optical connecting means as claimed in claim 1, wherein at least one body part of the mechanical connector has at least one apertured lug for use in detachably mounting the body part on a support.

2. Means for effecting disconnectable optical connections between multiplicities of optical guides, which optical connecting means comprises a mechanical connector comprising two separately formed body parts adapted to make a disconnectable plug and socket connection the one with the other and a plurality of optical fibre connectors each comprising at least two separately formed mating body parts, each of which mating body parts has at least one substantially flat end face with which end faces of a plurality of optical fibres secured in said body part are substantially co-planar, one body part of each of the plurality of optical fibre connectors being slidably mounted in and with respect to one body part of the mechanical connector with its axis substantially parallel to the axis of said body part of the mechanical connector and with each of its optical fibres adapted to be optically connected to one of a multiplicity of optical guides and being urged by resilient means housed in said body part of the mechanical connector in a rectilinear direction substantially parallel to said axes towards the mating end of said body part of the mechanical connector, and another body part of each optical fibre connector being fixedly secured in and with respect to the other body part of the mechanical connector with its axis substantially parallel to the axis of the other body part of the mechanical connector and with each of its optical fibres adapted to be optically connected to one of another multiplicity of optical guides.

3. Optical connecting means as claimed in claim 2, wherein each optical fibre connector is a two-part plug and socket optical fibre connector.

4. Optical connecting means as claimed in claim 2, wherein the axes of the plurality of optical fibres of each optical fibre connector body part over at least parts of the lengths of the fibres extending from the mating end face of said optical fibre connector body part lie in a substantially common plane.

Optical connecting means as claimed in claim 5, wherein the plurality of optical fibre connector body parts accommodated in each body part of the mechanical connector are disposed side-by-side with said substantially common planes of the axes of said parts of the lengths of their optical fibres lying substantially parallel to one another.

7. Optical connecting means as claimed in claim 6, wherein each of the plurality of optical fibre connector body parts accommodated in each body part of the mechanical connector has a single flat mating end face and the flat mating end faces of said plurality of optical fibre connector body parts lie in a common plane which is substantially normal to the common planes in which lie the axes of said parts of the lengths of the optical fibres and longitudinal axis of each optical fibre connector body part.

8. Optical connecting means as claimed in claim 5, wherein one body part of each optical fibre connector has a pair of substantially rigid pins protruding from its mating end face substantially parallel to the central longitudinal axis of the body part and disposed on transversely opposite sides of the optical fibres secured in the body part, the axes of the pins lying in the same substantially common plane as the axes of said parts of the lengths of the optical fibres, and the other body part of each optical fibre connector has a pair of holes extending substantially parallel to the central longitudinal axis of said other body part and disposed on transversely opposite sides of the optical fibres secured in said other body part, the axes of said holes lying in the same substantially common plane as the axes of said parts of the lengths of the optical fibres.

9. Optical connecting means as claimed in claim 8, wherein the fixed body part of each optical fibre connector has a pair of substantially rigid pins protruding from its mating end face and serving to effect a plug and socket connection with holes in the other body part of said optical fibre connector.

10. Optical connecting means as claimed in claim 5, wherein the end face of at least one body part of each of the plurality of optical fibre connectors is set back from the mating end face of the body part of the mechanical connector in which it is mounted.
