Positioning of adaptors for optical connectors

1. An assembly of a mounting support and an optical fibre connector adaptor mounted on the support, wherein the adaptor has a connector-receiving axis and at least one lateral mounting projection on at least a first one of its sides, and the mounting support comprises wall members upstanding from the support on both sides of the said adaptor, which wall members on at least one side of the adaptor define mounting slots adapted to receive the said mounting projections of the adaptor, and wherein the slots are formed to permit movement of the adaptor between at least a first position in which the adaptor is supported with its said axis at an acute angle to the support, and a working position in which the adaptor is supported with its said axis lying substantially parallel to the support, and wherein the wall members define, in at least one of the said slots, at least one shoulder on which one of the mounting projections of the adaptor can be supported, and at least one resilient portion of the wall member is arranged adjacent the shoulder to retain that mounting projection removably on the said shoulder, wherein the adaptor has at least two mounting projections on each of its sides, wherein the mounting support has at least two slots in each wall to receive the mounting projections on each of its sides, wherein the mounting support has at least one shoulder in each said slot; and wherein the shoulders at one end are at a different level than the shoulders at the other end, whereby the adaptor is held at the acute angle by virtue of the engagement of the projections at varying height shoulders.

2. An assembly according to claim 1 , wherein the slots are arranged to hold the adaptor loosely in the said working position.

3. An optical assembly, comprising:

an optical fibre connector adaptor wherein the adaptor has a connector-receiving axis and at least one mounting projection on at least a first one of its sides lateral to the connector-receiving axis, and

a mounting support defining at least one mounting slot, at least one upwardly facing shoulder on which the at least one mounting projection of the adaptor can be supported, and at least one resilient portion being arranged to retain that mounting projection removably on the least one shoulder; wherein

the adapter is mountable on the support with the slot formed to permit movement of the adaptor between at least a first position in which the adaptor is supported with its said axis at an acute angle to the support, and a working position in which the adaptor is supported with its said axis lying substantially parallel to the support, wherein the adaptor has at least two mounting projections on each of its sides, wherein the mounting support has at least two slots in each wall to receive the mounting projections on each of its sides, wherein the mounting support has at least one shoulder in each said slot; and wherein the shoulders at one end are at a different level than the shoulders at the other end, whereby the adaptor is held at the acute angle by virtue of the engagement of the projections at varying height shoulders.

4. An assembly according to claim 3 , wherein the mounting support comprises wall members upstanding from the support on both sides of the said adaptor.

5. An assembly according to claim 4 , wherein the wall members define the mounting slot adapted to receive the said mounting projection of the adaptor.

6. An assembly according to claim 3 , wherein the slots are arranged to hold the adaptor loosely in the said working position.

7. An assembly according to claim 3 , wherein the slots have a width at least twice the width of the projections.

8. An assembly according to claim 3 , wherein each of the slots include downwardly extending slot portions extending from a front edge of the shoulders, whereby the adaptor may be moved forwardly to a position where the projections clear the shoulders and extend downwardly into the downwardly extending slot portions.
