FIBER OPTIC CONNECTOR HAVING SEALS

摘要

PURPOSE: A fiber optic connector is provided to allow light from the light source to be efficiently coupled into the fiber optic light cable. CONSTITUTION: The end portion(18) of the light source housing(16) is moved axially toward the spud(38) such that the spud(38) and ferrule(28) are disposed in the cavity(20). The end portion(18) is moved over the spud(38) to compress the first seals(64) and the flange(22) enters the access opening(58) in the cage(50). The flange(22) deflects the spring(62) radially and moves axially past the spring(62). The spring(62) returns radially and is disposed between the flange(22) and flange portion(56) to secure the end portion(18) in place on the spud(38). The fiber optic connector(10) retains the fiber optic light cables(12 and 14) from moving axially to ensure light transmission efficiency. The fiber optic connector(10) also seals a joint between the coupling(26) and light source housing(16) with the first seals(64) to keep environmental contaminants out of the light source housing(16). The first seals(64) are used to minimize the lateral movement as well as providing a seal. A service tool(not shown) is used to disconnect the coupling(26) and light source housing(16). It should be appreciated that the service tool is conventional and known in the art. It should be appreciated that the fiber optic connector(10) serves as an attachment for connecting two fiber optic light cables(12,14).
