Optical fiber connector
An optical fiber connector includes a housing with at least one elongated cylindrical cavity, a fiber holder within the cavity including a ferrule which secures an optical fiber therein and a biasing member engaging the fiber holder to bias the ferrule towards an unmated position. A resilient metal latch is mounted on the housing for releasably securing the optical fiber connector to another component. A latch travel limiting structure prevents the latch from deflecting outside a desired predetermined path. Improved structures for mounting the latch on the housing and for creating a duplex connector assembly are also provided.
1. An optical fiber connector, the optical fiber connector comprising:
a housing, the housing including at least one elongated cylindrical cavity;
a fiber holder, the fiber holder being disposed within the cavity, the fiber holder including a ferrule, the ferrule securing an optical fiber therein;
a biasing member, the biasing member engaging the fiber holder to bias the ferrule towards an unmated position;
a resilient metal latch, the resilient metal latch including a mounting portion for securing the resilient metal latch to the housing, a manually manipulatable portion and at least one latching member for releasably securing the optical fiber connector to another component; and
a latch travel limiting structure, the latch travel limiting structure being configured to engage the resilient metal latch to prevent the resilient metal latch from deflecting beyond an upper and lateral limits.
2. The optical fiber connector of claim 1 , wherein the latch travel limiting structure includes a vertical stop surface to prevent the resilient metal latch from deflecting away from the housing more than a predetermined distance.
3. The optical fiber connector of claim 2 , wherein the latch travel limiting structure further includes lateral stop surfaces to prevent the resilient metal latch from deflecting out of a common plane extending through a longitudinal axis of the optical fiber connector and a longitudinal axis of the resilient metal latch.
4. The optical fiber connector of claim 3 , wherein the latch travel limiting structure is a metal component including a latch receiving hole therein, with a portion of the resilient metal latch extending through the latch receiving hole.
5. The optical fiber connector of claim 1 , further comprising a member for securing both the fiber holder within the elongated cylindrical cavity and the latch travel limiting structure to the optical fiber connector.
