摘要： Optical fiber connector assemblies. The connectors comprise plug bodies having two cantilevered beams disposed in a rear interior portion of the plug body and a ferrule which houses an optical fiber that is front-loaded into the plug body and which is adapted to bias the two cantilevered beams when placed in the plug body such that the plug body snaps around the plug member to captivate the ferrule member in the optical fiber connector. The connector is further comprised of a spring placed axially in the plug body for spring-loading the ferrule member in the plug body, and a rear housing adapted to receive the rear portion of the ferrule member when the ferrule member is placed in the plug body. The optical fiber connectors which are described herein ensure precise optical alignment of optical waveguides in the connector and are simple to assemble.

摘要： A novel forward-facing, aft-attached cantilever beam is provided as a latch for securing a fiber optic connector to a receptacle. The beam has engagement structure on its free end which attaches to the receptacle. The connector includes a plug housing formed from a member having a forward end and a rearward end and an axial passageway therethrough through which at least one optical fiber provided in the fiber optic cable extends. The forward end is inserted into the receptacle with the rearward end extending from the receptacle. The cantilevered beam has an end fixed to a rearward portion of the member and its free end extends forwardly toward the forward end of the member. To engage the connector with the receptacle, the free end of the cantilevered beam is biased toward the member and the member is slid into the receptacle. Once fully inserted, the engagement structure on the cantilevered beam engages retention structure in the receptacle. The connector can be released from engagement with the receptacle by biasing the cantilevered beam such that the engagement structure on the beam is released from the retention structure of the receptacle and thereafter pulling the connector out of the receptacle.

摘要： A fiber optic connector utilizing a fiber array ferrule 20 has a housing 1 with an internal geometry that provides transverse alignment of the ferrule relative to the housing 1 when the connector is in an unmated condition and permits transverse displacement of the ferrule relative to the housing when the connector is in a mated condition. This structure advantageously permits proper pre-mating alignment with a mating connector ferrule or other optical device while also improving isolation of the ferrule from external loads imposed on the housing 1 when the connector is in a mated condition.

摘要： A connector system having tab-like male terminal with stopping shoulders and a female terminal contained in a housing which has an opening for insertion of the male terminal into the female terminal. To provide needed electrical isolation for the female terminal in its unmated condition, the housing extends beyond the male tab receiving outer edge of the female terminal a predetermined distance D.sub.1. Because of industry length standards for male tab terminals the shoulders thereon must abut against the outer edge of the female terminal for proper mating. Thin membranes, which are slitted, are formed in the housing to mate with the male tab shoulders and extend from the outer edge of the housing to a distance back of the outer edges of the female terminal to enable the male tab shoulders to push aside the slitted, thin membranes and abut against the outer edge of the female terminal.
