  • Patent number: 9158076
    Abstract: An on-site hot-melt quick connector for optical fibers comprises a plug housing, a ferrule, an optical fiber telescopic protective tube, a tail end cover, a pressure welding protective tail handle and a compression ring. A front baffle ring is mounted in the plug housing and a rear baffle ring is mounted in the tail end cover. The ferrule and the optical fiber telescopic protective tube are positioned between the front baffle ring and the rear baffle ring and can move in the axial direction. As the quick connector for optical fibers of the invention has a definite space for movement in the axial direction, the optical fibers themselves can move along with the plugging action during butting, avoiding the bending of the optical fibers caused as they are unable to move, thus guaranteeing the transmission quality of the optical signals. The service life of the quick connector is also guaranteed.

  • Patent number: 8702317
    Abstract: An optical connector having an optical fiber inserted into a connector main body includes a buckling regulating section whose length in an optical fiber insertion direction is formed variable and which regulates a buckling of the optical fiber while becoming short in an optical fiber insertion direction when the optical fiber is inserted into the connector main body. Even if an insertion area is made long, since no buckling of the optical fiber is generated, the buckling regulating section can sufficiently increase an insertion force of the optical fiber. Thus, even when foreign substances such as dusts enter and an insertion resistance increases, the optical fiber can be securely inserted. Further, the buckling regulating section is very advantageous to realize an end surface preparation of the optical fiber making use of the insertion force of the optical fiber such as a coating removing of the optical fiber, and an end surface grinding preparation of the optical fiber.

  • Patent number: 8702323
    Abstract: A connector including a housing having a distal end and a proximal end has a ferrule assembly having a ferrule and a ferrule spring. The ferrule spring biases the ferrule in a distal direction. A boot is mounted at the proximal end. The boot has a distal end mounting over the proximal end of the housing and a proximal end and defines a central axis. A central passage extends through a length of the boot. A strain relief portion is adjacent the proximal end of the boot and has a truncated, conical outer shape formed by co-axial rings separated by gaps, the rings being interconnected by links extending across the gaps. The central passage has a proximal portion corresponding to a length of the strain relief portion that defines a transverse cross-dimension A majority of the rings have radial thicknesses at least 50 percent as long as the transverse cross-dimension.

  • Patent number: 8662760
    Abstract: A fiber optic connector that employs an optical fiber guide member, and a cable assembly that uses the connector are disclosed. The connector has a connector housing formed by mateable sections. The connector housing defines a housing passage having opposite connector-end and channel-end portions that define respective connector-end and channel-end passages, with the channel-end portion configured to be arranged adjacent the end of a fiber optic cable. An optical fiber guide member is disposed in the channel-end passage and has a first transition end that faces the connector-end passage. The optical fiber guide member has a conduit configured to loosely confine and guide the optical fibers to the connector-end passage. Connector sub-assemblies can be operably supported at the connector-end portion supporting end portions of the optical fiber.

  • Patent number: 8573858
    Abstract: An assembly includes a connector and a carrier engaged therewith. Connector has a first mating end and a second end and a first fiber. The fiber defines a first end adjacent the mating end and a second end protruding from the connector second end. Carrier has a connector end and an opposite cable end and includes a heat activated meltable portion adjacent the cable end. An alignment structure is on the carrier and includes first and second ends, and a throughhole. The first end of the alignment structure receives the second end of the first fiber and the second end receives an end of a second fiber entering the carrier. The heat activated portion melts and assumes a flowable condition when exposed to a predetermined amount of heat and resolidifies when heat is removed, bonding the second fiber to the carrier after the first and second fibers are aligned.
