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.Wherein porcelain bushing 102 is the LC type porcelain bushing of standard openings.
Because the singularity of porcelain bushing 102 assemblings, metalwork 101 has been split as the first metalwork 101A of fixation and the second metalwork 101B that shields usually.During the optical fiber assembling; at first optical fiber contact pins 103 is inserted porcelain bushing 102; inserted the first metalwork 101A of fixation at the porcelain bushing 102 that will comprise optical fiber contact pins 103, and then the first metalwork 101A and the second metalwork 101B that shields have been assembled up.But, in the assembling process of the first metalwork 101A and the second metalwork 101B, need to use the guiding of Interference Fit Design and localization tool.As shown in Figure 2.Fig. 2 is the partial enlarged drawing of interference district 105 parts of the joints of optical fibre of Fig. 1, wherein, the interference part 105B after the interference district 105 of the second metalwork 101B comprises targeting part 105A and is positioned at targeting part 105A, wherein targeting part 105A is pyramidal structure.But because the targeting part 105A of this taper, the joints of optical fibre 100 that caused assembling with this kind usual manner can produce the unsettled problem of concentricitys, and exist the outward appearance of metalwork 101 to be directed to the hidden danger of tool scratch.
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: metalwork, porcelain bushing and optical fiber contact pins three parts.
Wherein, external diameter cylinder guide frame comprises: guide portion, transition shoulder district and interference district three parts.
Wherein, preferred implementation is: guide portion, comprise that the automatic guide of being responsible for before the first metalwork and the assembling of the second metalwork moves, its outside dimension parameter be the second metalwork interference internal orifice dimension lower limit-0.015mm in, length is greater than 0.5mm.
Wherein, preferred implementation is: the angular range in transition shoulder district is between 30 to 45 degree, wherein, is preferably 30 degree.
Wherein, preferred implementation is: the interference district make the first metalwork and the second metalwork two metalworks in conjunction with and the requirement of satisfying withdrawal force greater than 50 newton.
Compared with prior art, advantage of the present utility model and good effect are: the joints of optical fibre of the utility model design, solve the unsettled phenomenon of concentricity after the first metalwork and the second metalwork assembling process, and overcome before the potential problem of the scuffing metalwork that is brought by the localization tool correcting.
