Abstract

A fiber optic adapter for mating a multi-fiber optic ferrule connector and a multi-fiber optic connector. An engagement device may be integrated or molded as part of adapter receptacle at either end. The engagement device secures the multi-fiber connector. The adapter may be two-piece with a first portion detachable from a second portion, the first portion housing one or more integrated engagement devices and the second portion housing one or more replaceable engagement devices, or a receptacle configured to secure a latch configured on an outer housing of a connector. Receptacle may further contain a plural of engagement devices formed as a unitary engagement device.

Claims

1. A fiber optic adapter comprising:

a housing having a first end and a second end with one or more receptacles for receiving a connector,

each receptacle further comprises an integrated engagement device for securing the connector,

the integrated engagement device is formed as part of the receptacle,

the integrated engagement device further comprises a middle arm and two or more outer arms, and

wherein the middle arm lifts the outer arms when the middle arm is lifted by the connector inserted into the receptacle having the engagement device.

2. The fiber optic adapter of claim 1, wherein the two or more outer arms are received in a widthwise recess on surface of a connector.

3. The fiber optic adapter of claim 2, wherein the widthwise recess is a groove.

4. The fiber optic adapter of claim 1, wherein the integrated engagement device is molded as part of an inner housing of the receptacle.

5. The fiber optic adapter of claim 1, wherein the engagement device is ultrasonic welded to an inner housing of the receptacle.

6. The fiber optic adapter of claim 1, wherein a second end of the adapter receives a multi-fiber optic ferrule connector further comprising a latch on an outer housing of the connector, the latch is secured in an opening of the adapter housing.

7. A fiber optic adapter comprising:

a housing having a first body portion and a second body portion;

the first and second body portions are detachable;

the first body portion has one or more receptacles;

the receptacle further comprises an integrated engagement device therein for securing a connector,

the integrated engagement device further comprises a middle arm and two or more outer arms, and

wherein the middle arm lifts the outer arms when the middle arm is lifted by the connector inserted into the receptacle having the engagement device.

8. The fiber optic adapter of claim 7, wherein the integrated engagement device is molded as part of an inner housing of the receptacle.

9. The fiber optic adapter of claim 7, wherein the engagement device is ultrasonic welded to an inner housing of the receptacle.

10. The fiber optic adapter of claim 7, wherein a second end of the adapter receives a multi-fiber optic ferrule connector further comprising a latch on an outer housing of the connector, the latch is secured in an opening of the adapter housing.

11. The fiber optic adapter of claim 7, wherein the connector has a recess on a side to accept engagement device for securing connector within receptacle.

12. A fiber optic adapter comprising:

a housing having a first end and a second end;

the first or second end having a plural of receptacles;

a first receptacle at the first end further comprising an integrated engagement device for securing a multi-fiber optic connector therein;

a second receptacle further comprising an opening on a side, the opening accepts a latch on an outer housing of a multi-fiber optic ferrule connector for securing the multi-fiber optic ferrule connector therein;

the integrated engagement device further comprises a flexible tab and two or more arms, and

wherein the flexible lifts the arms when the flexible tab is lifted by the connector inserted into the receptacle having the engagement device.

13. The fiber optic adapter of claim 12, wherein the housing comprises a first portion and a second portion separating the first end from the second end.

14. The fiber optic adapter of claim 13, wherein the first and the second portion are secured using clips.
