Abstract

Disclosed are optical plug connectors and optical receptacles for making optical connections. In one embodiment, the optical plug connector includes an optical portion having an optical interface and a cover for protecting the optical interface. The cover can translate toward the optical interface when connecting the optical plug connector and a portion of the cover allows transmission of optical signals therethrough. The cover has a sliding fit relative to a portion of the housing and may translate on at least one guide surface of the housing.

First claim

We claim:

1 . An optical plug connector, comprising:
an optical portion having an optical interface; a cover for protecting the optical interface, wherein the cover can translate toward the optical interface when connecting the optical plug connector and a portion of the cover allows transmission of optical signals therethrough; and a housing having at least one guide surface, wherein a portion of the cover has a sliding fit relative to a portion of the housing and may translate relative to the at least one guide surface of the housing.

2 . The optical plug connector of claim 1 , wherein a portion of the cover fits about a portion of the housing.

3 . The optical plug connector of claim 1 , wherein a portion of the cover is received into an end portion of the housing.

4 . The optical plug connector of claim 1 , wherein the cover has a front face footprint that is least 70 percent of a cross-sectional area of the optical plug connector.

5 . The optical plug connector of claim 1 , wherein the cover is operable to translate 3 millimeters or more towards the optical interface.

6 . The optical plug connector of claim 1 , wherein the housing includes a medial portion and the at least one guide surface is disposed on the medial portion.

7 . The optical plug connector of claim 1 , further including one or more cover guides, wherein the cover guides are one or more alignment pins and the cover includes one or more bores for receiving the one or more alignment pins.

8 . The optical plug connector of claim 1 , further including one or more cover guides, wherein the cover guides are one or more electrical contacts and the cover includes one or more bores for receiving the one or more electrical contacts.

9 . The optical plug connector of claim 1 , further including one or more resilient members for biasing the cover toward a forward position.

10 . The optical plug connector of claim 1 , wherein the optical portion has a nose that engages a cavity of the cover when in a retracted position.

11 . The optical plug connector of claim 1 , wherein the cover includes one or more cover guides.

12 . The optical plug connector of claim 1 , the cover including a body and a window attached to the body, wherein the window allows the transmission of optical signals therethrough.

13 . The optical plug connector of claim 1 , wherein the cover is formed as single component.

14 . The optical plug connector of claim 1 , further including one or more electrical contacts.

15 . The optical plug connector of claim 1 , the optical interface including a plurality of lenses integrally formed in the optical portion.

16 . The optical plug connector of claim 1 , further including a fiber organizer.

17 . The optical plug connector of claim 1 being a portion of a cable assembly.

18 . The optical plug connector of claim 15 , further including a crimp band.

19 . The optical plug connector of claim 1 , wherein the cover may be removed and replaced.

20 . An optical plug connector, comprising:
an optical portion having an optical interface; one or more alignment pins; a cover for protecting the optical interface, the cover includes one or more bores for receiving the one or more alignment pins, wherein the cover can translate toward the optical interface when connecting the optical plug connector and a portion of the cover allows transmission of optical signals therethrough; and a housing having at least one guide surface, wherein a portion of the cover has a sliding fit relative to a portion of the housing and may translate relative to the at least one guide surface of the housing.

21 . The optical plug connector of claim 20 , wherein a portion of the cover fits about a portion of the housing.

22 . The optical plug connector of claim 20 , wherein a portion of the cover is received into an end portion of the housing.

23 . The optical plug connector of claim 20 , wherein the housing includes a medial portion and the at least one guide surface is disposed on the medial portion.

24 . The optical plug connector of claim 20 , further including one or more resilient members for biasing the cover toward a forward position.

25 . The optical plug connector of claim 20 , wherein the optical portion has a nose that engages a cavity of the cover when in a retracted position.

26 . The optical plug connector of claim 20 , wherein the cover includes one or more cover guides.

27 . The optical plug connector of claim 20 , the cover including a body and a window attached to the body, wherein the window allows the transmission of optical signals therethrough.

28 . The optical plug connector of claim 20 , wherein the cover is formed as single component.

29 . The optical plug connector of claim 20 , further including one or more electrical contacts.

30 . The optical plug connector of claim 20 , the optical interface including a plurality of lenses integrally formed in the optical portion.

31 . The optical plug connector of claim 20 being a portion of a cable assembly.

32 . The optical plug connector of claim 31 , further including a crimp band.

33 . The optical plug connector of claim 20 , wherein the cover may be removed and replaced.

34 . An optical plug connector, comprising:
an optical portion having an optical interface; a fiber organizer for receiving optical fibers a cover for protecting the optical interface, wherein the cover can translate toward the optical interface when connecting the optical plug connector and a portion of the cover allows transmission of optical signals therethrough; and a housing having at least one guide surface, wherein a portion of the cover has a sliding fit relative to a portion of the housing and may translate relative to the at least one guide surface of the housing.

35 . The optical plug connector of claim 34 , wherein the cover includes one or more cover guides.

36 . The optical plug connector of claim 34 , the cover including a body and a window attached to the body, wherein the window allows the transmission of optical signals therethrough.

37 . The optical plug connector of claim 34 , wherein the cover is formed as single component.

38 . The optical plug connector of claim 34 , further including one or more electrical contacts.

39 . The optical plug connector of claim 34 , the optical interface including a plurality of lenses integrally formed in the optical portion.

40 . The optical plug connector of claim 34 being a portion of a cable assembly.

41 . The optical plug connector of claim 40 , further including a crimp band.

42 . The optical plug connector of claim 34 , wherein the cover may be removed and replaced.
