The utility model discloses a novel plug-pull fiber connector and a light-emitting assembly thereof. The novel plug-pull fiber connector comprises a pipe cap and a fiber light penetrating hole, wherein the pipe cap is made from polyetherimide (PEI) engineering plastics; the fiber light penetrating hole is arranged inside the pipe cap; an isolator is stuck on the fiber connector through the glue sealing technology; and the inner diameter of the magnetic pipe of the isolator is the same as the diameter of the fiber light penetrating hole. The novel plug-pull fiber connector solves the problems that the fiber connector is poor in stability and unsatisfactory in electrical isolation function in the process of reliability test.
Description
Technical field
The utility model relates to the joint in the fiber optic communication field, particularly a kind of the joints of optical fibre and light emission component thereof of novel plug-in.
Background technology
The joints of optical fibre, optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it gets up the accurate docking of two end faces of optical fiber, go so that the luminous energy of launching fiber output can be coupled to receive in the optical fiber to greatest extent, and make because it is got involved light path and the impact that system causes is reduced to minimum.To a certain extent, the joints of optical fibre have affected reliability and the properties of optical transmission system.Please refer to the structural drawing of the existing joints of optical fibre shown in Figure 1.Wherein, the joints of optical fibre 100 include metalwork 101, porcelain bushing (Sleeve) 102 and optical fiber contact pins (Fiber Stub) 103 compositions.Because the singularity of porcelain bushing 102 assemblings, metalwork 101 is split as the first metalwork 101A and the second metalwork 101B usually.During the optical fiber assembling; at first optical fiber contact pins 103 is inserted porcelain bushing 102; the porcelain bushing 102 that will comprise again optical fiber contact pins 103 has inserted the first metalwork 101A of fixation, and then the first metalwork 101A and the second metalwork 101B that shields are assembled up.Wherein, isolated core 200 by laser welding process be arranged on the second metalwork 101B in, an end contacts with optical fiber contact pins 103, magnetic tube 300 is arranged in the second metalwork 101B and is positioned at the other end of isolated core 200.
But when carrying out reliability testing, the stability of the above-mentioned existing joints of optical fibre is also bad, and its electrical isolation function is also undesirable.
Summary of the invention
In order to solve problems of the prior art, the utility model provides a kind of novel joints of optical fibre.
The joints of optical fibre of the present utility model comprise: pipe cap and optical fiber light hole, and wherein, pipe cap adopts polyetherimide (PEI) engineering plastics to make, and it is inner that the optical fiber light hole is arranged on described pipe cap, and pipe cap and optical fiber light hole are symmetrical along center line.
Wherein, preferred implementation is: the optical fiber light hole of the joints of optical fibre comprises LC type and SC type.
The joints of optical fibre of the present utility model are applied in the light emission component, isolator are bonded on the above-mentioned joints of optical fibre by rubber seal technique, and with the consistent size of the diameter of the internal diameter size of the magnetic tube of isolator and above-mentioned optical fiber light hole.
Wherein, preferred implementation is: an adhesive curing is carried out in the place that the bottom of the magnetic tube of isolator and the pipe cap of the joints of optical fibre contact with magnetic tube.
Compared with prior art, advantage of the present utility model and good effect are: point, and the first, these joints of optical fibre and light emission component material thereof change to the PEI engineering plastics by metal, have greatly improved the electrical isolation function; Secondly, the light hole of these joints of optical fibre can be designed to LC type or SC type; Again, light emission component is modified to rubber seal technique by original laser welding process, reduces stress relief and improves the stability of reliability testing; At last, light emission component of the present utility model is comprised of isolator and the joints of optical fibre, compares with the structure of before the joints of optical fibre, and production cost significantly reduces.
