Abstract

An optical connector is provided which requires less accurate machining during manufacture, can reduce the number and/or complexity of component parts required and can achieve a standard industrial product which nevertheless maintains very stable connections. In a receptacle for the optical connector, an alignment sleeve aligns and optically connects an optical fiber unit to another optical fiber unit or to an input/output window of other optical elements in a housing. The housing of the receptacle holds the sleeve in an alignment and is comprised of a plurality of housing halves joined along a major plane extending through the axis of the sleeve. The housing halves may include mating surfaces, projections or indents offset from said major plane.

Claims

1. A receptacle for an optical connector for connecting an active optical element to an optical fiber unit via an alignment sleeve capable of receiving the optical fiber unit, the receptacle including a housing having at least two halves and an optical component in which the active optical element is mounted in alignment with the alignment sleeve, wherein, upon assembling of the housing halves into the housing, the housing holds the optical component between opposing sides of the housing halves.

2. The receptacle according to claim 1, wherein a flange is formed on a housing section of the active component and recesses are provided as a one-end face side of the mating housing halves to hold the flange in place, upon the assembling of the housing halves into the housing, so that the housing section of the active component is held between the opposing sides of the housing halves.

3. The receptacle according to claim 1, wherein one of the housing halves has a projection at its mating side surface and the other housing half has a corresponding hole at its mating side surface so that, upon the assembling of the housing halves into the housing, the projection of said one housing half is fitted into the hole of said other housing half to achieve a positional alignment.

4. The receptacle according to claim 1, wherein the housing halves at a rear wall have associated grooved latch sections, respectively, and, upon the assembling of the housing halves into the housing, the grooved latch sections define a latch in which a support frame is fitted.

5. A component for an optical transmission system including an optical connector which comprises a receptacle according to claim 1.

6. A receptacle for an optical connector as claimed in claim 1, wherein the housing comprises a plurality of sections each divided into half-sections such that each half-section holds the alignment sleeve on the axis of the housing.

7. The receptacle according to claim 6, wherein a flange is formed on a housing section of the active component and recesses are provided as a one-end face side of the mating housing halves to hold the flange in place, upon the assembling of the housing halves into the housing, so that the housing section of the active component is held between the opposing sides of the housing halves.

8. The receptacle according to claim 6, wherein one of the housing halves has a projection at its mating side surface and the other housing half has a corresponding hole at its mating side surface so that, upon the assembling of the housing halves into the housing, the projection of said one housing half is fitted into the hole of said other housing half to achieve a positional alignment.

9. The receptacle according to claim 6, wherein the housing halves at a rear wall have associated grooved latch sections, respectively, and, upon the assembling of the housing halves into the housing, the grooved latch sections define a latch in which a support frame is fitted.

10. A component for an optical transmission system including an optical connector which comprises a receptacle according to claim 6.

11. A receptacle for an optical connector as claimed in claim 6, wherein the alignment sleeve lies in the dividing planes of the housing sections.

12. The receptacle according to claim 11, wherein a flange is formed on a housing section of the active component and recesses are provided as a one-end face side of the mating housing halves to hold the flange in place, upon the assembling of the housing halves into the housing, so that the housing section of the active component is held between the opposing sides of the housing halves.

13. The receptacle according to claim 11, wherein one of the housing halves has a projection at its mating side surface and the other housing half has a corresponding hole at its mating side surface so that, upon the assembling of the housing halves into the housing, the projection of said one housing half is fitted into the hole of said other housing half to achieve a positional alignment.

14. The receptacle according to claim 11, wherein the housing halves at a rear wall have associated grooved latch sections, respectively, and, upon the assembling of the housing halves into the housing, the grooved latch sections define a latch in which a support frame is fitted.

15. A component for an optical transmission system including an optical connector which comprises a receptacle according to claim 11.
