Abstract
The utility model provides a ceramic ferrule of an optical fiber connector for field assembly, which comprises a ferrule body. An optical fiber positioning through hole is arranged in the ferrule body along the length direction of the ferrule body, a section of pre-assembled optical fiber is embedded in the optical fiber positioning through hole, and a ventilation channel is also arranged in the ferrule body, and the ventilation channel passes through the optical fiber positioning through hole of the end of the pre-assembled optical fiber butted with field optical fiber in the optical fiber positioning through hole from the side surface of the ferrule body. The ventilation channel positioned on the pre-assembled optical fiber and the field optical fiber of the ceramic ferrule plays a role of venting air so that the pre-assembled optical fiber is butted with the field fiber to improve communication reliability and quality of the optical fiber, and the ceramic ferrule of the optical fiber connector for field assembly can realize multiple connections and disconnections and has excellent repeatability.
Description
Technical field
The utility model relates to a kind of field-installed joints of optical fibre that are used for, and relates in particular to ceramic insertion core wherein.
Background technology
Along with the communication and the fast development of Information Network road technique, especially Fiber to the home and the development and the utilization of technology such as fiber to the desk, and the scene of optical fiber is connected to become important component part in the networking.In recent years, the construction of fibre system has proposed very high request to the scene connection of optical fiber, not only requires to realize the connection of light path, also requires the effectively signal of the various Optical Fiber Transmission of connection, the decay that is luminous power need meet the demands, and repeatability and the stability for product has all proposed requirement simultaneously.
For a long time, for solving the problem that optical fiber field connects, when constructing at the scene, the constructor use the thermal welding technology to realize continuing of light path.But, the equipment investment that the thermal welding Technology Need is huge, and use hot melt equipment that environment is had higher requirement is as the power supply of the certain power of needs etc., its high use cost and need power supply not conveniently make it large-scale utilization and be restricted, thereby hindered fiber-to-the-home construction.For satisfy user's fiber to the desk, Fiber to the home high bandwidth and high speed rate communication requirement, and make distribution seem neatly agile, need a kind of joints of optical fibre that can assemble at the scene, this connector is to realize optical signal transmission effectively, and connector repeat assemble functional.
Ceramic insertion core is that the high-precision optical fiber that is used for the field-installed joints of optical fibre is aimed at bindiny mechanism, ceramic insertion core is provided with the fiber orientation hole, is assembled with optical fiber in the fiber orientation hole in advance, when assembling at the scene, field optical fibers penetrates from the other end in fiber orientation hole, docks with assembling optical fiber in advance.Find in practice, aim at performance although ceramic insertion core has high-precision optical fiber, but still the problem that light signal can't be connected often occurs.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ceramic insertion core that is used for the field-installed joints of optical fibre, can improve optical-fibre communications fiduciary level and quality.For this reason, the utility model is by the following technical solutions: it comprises the lock pin body, be provided with fiber orientation through hole in the described lock pin body along its length direction, be embedded with one section pre-assembling optical fiber in the described fiber orientation through hole, described lock pin body also is provided with gas-permeable channels, and described venting channels passes to the residing fiber orientation of that end through hole that described pre-assembling optical fiber docks with field optical fibers from the side surface of lock pin body in the fiber orientation through hole.Owing to adopt the technical solution of the utility model, the venting channels that is positioned at pre-assembling optical fiber and field optical fibers joint on the ceramic insertion core plays the effect of discharging air, make pre-assembling optical fiber and field optical fibers to dock well, improve optical-fibre communications fiduciary level and quality, can realize repeatedly connecting and disconnect and have a good reproducibility.
On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme:
Inwardly bury described one section pre-assembling optical fiber underground from the one end in the described fiber orientation through hole.
Described gas-permeable channels is a slit.Described gas-permeable channels also can be structures such as circular hole.

Fig. 1 is the schematic perspective view of embodiment provided by the utility model.
Fig. 2 is the cut-open view of embodiment provided by the utility model.
Embodiment
With reference to accompanying drawing.The utility model comprises lock pin body 1, and the side surface 1-1 of lock pin body 1 is cylindrical, and the diameter of lock pin body 1 is 2.5 millimeters.Be provided with fiber orientation through hole 1-2 in the described lock pin body 1 along its length direction, its diameter is 0.125 millimeter, be embedded with one section pre-assembling optical fiber 2 among the described fiber orientation through hole 1-2, pre-assembling optical fiber 2 is fixed among the fiber orientation through hole 1-2 by epoxy glue, described lock pin body also is provided with gas-permeable channels 1-3, and described venting channels 1-3 passes to the residing fiber orientation of that end 2-2 through hole that described pre-assembling optical fiber docks with field optical fibers from the side surface 1-1 of lock pin body in the fiber orientation through hole.Field optical fibers 3 enters into fiber orientation through hole 1-2 by the pilot hole 1-4 on the lock pin body 1, and docks at venting channels 1-3 place with an end 2-2 of pre-assembling optical fiber 2, realizes accurately location.
Described one section pre-assembling optical fiber is inwardly laid from described fiber orientation through hole one end.The pre-assembling optical fiber end 2-1 that is in fiber orientation through hole aperture can grind in factory, obtains to have good geometrical performance,
Described gas-permeable channels is a slit.
Above-mentioned concrete step is all only given an example for convenience of description, is not the restriction to the utility model scope.For the general personnel in present technique field, can under situation that does not break away from spirit of the present utility model and scope, make many variations.Therefore, all technical schemes that are equal to also belong to protection domain of the present utility model.
