Mini duplex connector with push-pull polarity mechanism and carrier using rail receiving portions
A new fiber optic connector provides a smaller form factor by including two ferrule assemblies in a housing. The housing accepts a push-pull mechanism that allows for insertion and removal from a carrier as well as an adapter. The push-pull mechanism may also include a flexure member to return the push-pull mechanism. Polarity of the fiber optic connector may also be selected by use of the push-pull mechanism.
1. A fiber optic connector comprising:
a housing having a main body extending between a front end and a rear end and having an opening extending therebetween;
two ferrule assemblies disposed within the opening of the housing, each of the ferrule assemblies comprising a fiber optic ferrule, a ferrule holder, the fiber optic ferrule being inserted into a front end of the ferrule holder and extending away from the front end of the ferrule holder;
two springs, each spring engaging a rearward facing surface of a respective ferrule holder and extending towards the rear end of the housing to bias the ferrule assemblies toward the front end of the housing and retained within the housing; and
a crimp body having a rail receiving portion extending along a first surface to receive a portion of a latch component and aligned with a rail receiving portion of the housing.
2. The fiber optic connector according to claim 1 , further comprising a spring push engaging a rear portion of each of the two springs.
3. The fiber optic connector according to claim 1 , wherein the rail receiving portion extends along at least a portion of the housing.
4. The fiber optic connector according to claim 1 , further comprising:
a crimp band secured around an outer surface of a rear end of the crimp body; and
a strain relief boot attached to the crimp body and crimp band and extending rearwardly away from the housing.
5. The fiber optic connector according to claim 1 , further comprising an indicia of polarity on the housing.
6. The fiber optic connector according to claim 1 , wherein the rail receiving portion has a dove tail configuration or an undercut configuration.
7. The fiber optic connector according to claim 1 , wherein the latch component is a push-pull mechanism.
8. The fiber optic connector according to claim 7 , wherein the push-pull mechanism includes a latch for a carrier and a latch for a fiber optic connector adapter.
9. A housing for a fiber optic connector, comprising:
a main body extending between a front end and a rear end and having an opening extending therebetween to receive a ferrule assembly and a spring;
a forward facing surface to engage a rear end of the spring to forward bias the ferrule assembly inside the opening;
a rail receiving portion extending along at least a portion of the housing and having a stop surface adjacent the front end to slidably receive a latch component;
at least two longitudinal portions on a top surface and a bottom surface of the housing to align the housing with an adapter; and
a crimp body attached to the rear end of the housing and having a transition area for optical fibers received in the housing.
10. The housing according to claim 9 , further comprising a structure inside the opening to prevent a rotation of the ferrule assembly.
11. The housing according to claim 10 , wherein the structure is a flat surface to engage a corresponding flat surface of a ferrule holder of the ferrule assembly.
12. The housing according to claim 9 , the crimp body having a rail receiving portion extending along a first surface to receive a portion of a latch component and aligned with a rail receiving portion of the housing.
13. The fiber optic connector according to claim 9 , further comprising an indicia of polarity on the housing.
14. The fiber optic connector according to claim 9 , further comprising:
a crimp band secured around an outer surface of a rear end of the crimp body; and
a strain relief boot attached to the crimp body and the crimp band and extending rearwardly away from the housing.
15. A fiber optic connector comprising:
a housing having a main body extending between a front end and a rear end and having an opening extending therebetween, and a rail receiving portion extending along a portion of the housing;
two ferrule assemblies disposed within the opening of the housing, each of the ferrule assemblies comprising a fiber optic ferrule, a ferrule holder, the fiber optic ferrule being inserted into a front end of the ferrule holder and extending away from the front end of the ferrule holder;
two springs, each spring engaging a rearward facing surface of a respective ferrule holder and extending towards the rear end of the housing to bias the ferrule assemblies toward the front end of the housing and retained within the housing; and
a crimp body having a rail receiving portion extending along a first surface to receive a portion of a latch component and aligned with the rail receiving portion of the housing.
