Abstract

A connector assembly includes an adapter, a housing device, a ferrule assembly, and a sensor. The housing device is received by the adapter and has a bore, a front end, and a rear end opposite the front end. A ferrule of the ferrule assembly is within the bore of the housing device and has a mating end extending beyond the front end of the housing device. The sensor is mounted on the rear end of the housing, the rear end of the ferrule assembly, or on the adapter confronting and spaced apart from the housing device or the ferrule assembly. The sensor is configured for detecting a force applied by the housing device or the ferrule assembly, respectively. An electrical characteristic of the sensor changes to indicate a predetermined force has been applied by the housing device or the ferrule assembly, respectively.

Claims

1. A connector assembly comprising:

a housing device including a housing receivable by the adapter and having a bore, the housing device further including a front end, a rear end opposite the front end, and a first housing wall such that when the first housing wall is received in the adapter and is on an inner side of the first adapter wall, the first adapter wall facing a first direction, movement of the first housing wall in a second direction opposite the first direction is limited by the first adapter wall;

a ferrule within the bore of the housing and having a mating end extending beyond the front end of the housing device;

a sensor mounted on the rear end of the housing device or mounted on the adapter such that the sensor confronts the rear end of the housing device, the sensor being configured for detecting a force applied by the rear end of the housing device, wherein an electrical characteristic of the sensor changes to indicate a predetermined force has been applied by the housing device.

2. The connector assembly of claim 1, wherein the first housing wall is movable when the first housing wall is received in the adapter and is on the inner side of the first adapter wall.

3. The connector assembly of claim 1, wherein the adapter includes a second adapter wall opposing the first adapter wall, and wherein the first housing wall is between the first and the second adapter walls when the first housing wall is received in the adapter and is on the inner side of the first adapter wall.

4. The connector assembly of claim 3, wherein the housing device includes a second housing wall opposite the first housing wall, and wherein when the first housing wall is received in the adapter and is on the inner side of the first adapter wall, the first housing wall faces the first adapter wall to define a first distance therebetween and the second housing wall faces the second adapter wall to define a second distance therebetween, and wherein the sum of the first and the second distances is greater than zero.

5. The connector assembly of claim 4, wherein the first distance is a first clearance defined by a peak of the first housing wall and a peak of the first adapter wall, wherein the second distance is a second clearance defined by a peak of the second housing wall and a peak of the second adapter wall, and wherein the sum of the first and the second clearances is at least 0.1 mm.

6. The connector assembly of claim 1, wherein the first housing wall is defined by a step of a lever of an LC connector, and wherein the first adapter wall is a portion of a hole extending through or a portion of a cavity extending within the adapter such that the step of the lever is received in the hole or the cavity extending within the adapter when the first housing wall is received in the adapter.

7. The connector assembly of claim 1, wherein the housing device forms part of an SC connector, the housing defining a groove and including a protrusion acting as a catch, the first housing wall defining a portion of the groove, and wherein the first adapter wall defines an end of a flange such that the end of the flange is received in the groove of the housing when the first housing wall is received in the adapter.

8. The connector assembly of claim 1, wherein the adapter includes a base plate and the sensor is mounted on the base plate.

9. The connector assembly of claim 1, wherein the sensor is mounted on the rear end of the housing device, and wherein the adapter includes a base plate and a post extending from the base plate such that the sensor is in abutment with the post when the sensor detects the force applied by the rear end of the housing device.

10. The connector assembly of claim 1, wherein the housing device further includes an extension device extending from a rear end of the housing, and wherein a rear end of the extension device defines the rear end of the housing device.

11. The connector assembly of claim 10, wherein the sensor is in abutment with the rear end of the extension device when the sensor detects the force applied by the rear end of the housing device.

12. The connector assembly of claim 1, wherein the sensor is outside the adapter such that the sensor is exposed.

13. A connector assembly comprising:

an adapter including a first adapter wall;

a housing device including a housing receivable by the adapter and having a bore, the housing device further including a front end, a rear end opposite the front end, and a first housing wall such that when the first housing wall is received in the adapter and is on an inner side of the first adapter wall, the first adapter wall facing a first direction, movement of the first housing wall in a second direction opposite the first direction is limited by the first adapter wall;

a ferrule within the bore of the housing and having a mating end extending beyond the front end of the housing device;

a sensor mounted on the rear end of the housing device or mounted on the adapter such that the sensor confronts the rear end of the housing device, the sensor being configured for detecting translation of the housing device, wherein an electrical characteristic of the sensor changes to indicate translation of the housing device to a predetermined position.

14. A connector assembly comprising:

an adapter;

a housing device including a housing receivable by the adapter and having a bore, a front end, and a rear end opposite the front end, the bore of the housing defining an opening at the rear end of the housing device;

a ferrule assembly including a ferrule within the bore of the housing and having a mating end extending beyond the front end of the housing device, the ferrule assembly having a front end and a rear end opposite the front end of the ferrule assembly;

a sensor mounted on the rear end of the ferrule assembly or on the adapter such that the sensor confronts the rear end of the ferrule assembly, the sensor including a probe and being configured for detecting either one or both of (i) a force applied by the rear end of the ferrule assembly and (ii) translation of the ferrule assembly, wherein the probe is aligned with the ferrule assembly such that the ferrule assembly is in contact with the probe when the sensor detects the respective one of the force applied by the rear end of the ferrule assembly or translation of the ferrule assembly,

wherein an electrical characteristic of the sensor changes to indicate (i) a predetermined force has been applied by the ferrule assembly when the sensor is configured for detecting a force applied by the rear end of the ferrule assembly or (ii) a translation of the ferrule assembly to a predetermined position when the sensor is configured for detecting translation of the ferrule assembly.

15. The connector assembly of claim 14, wherein the adapter includes a base plate and the sensor is mounted on the base plate.

16. The connector assembly of claim 14, wherein the adapter includes a base plate and a post extending from the base plate such that the sensor is in abutment with the post when the sensor detects the respective one of the force applied by the rear end of the ferrule assembly or the translation of the ferrule assembly.
