Therefore, optical cable 100 firmly is fixed in tail cover portion 12 and the upper shield 20 because of a plurality of cast projection 12b, 22 and a plurality of pressurization projection 24a, 24b, 24c, places plug 10 inside simultaneously.
At last, plug 10 is inserted in the connector shell 80, finally finish light connection and assembling.
When finishing light connection and assembling, in the process on being installed in connecting box, optical cable 100 can be crooked, this moment, tail cover portion 12 and upper shield 20 had 50 millimeters length with the connecting portion of screw cap 70, along with being shorter in length than 50 millimeters, 100 on optical cable is more crooked, thereby also can install in the connecting box of small dimension.
More than explanation is the explanation of carrying out for the fixation procedure of circular optical cable 100 as shown in the figure, and the assembled on site type optical connector of another embodiment of the present invention also can firmly be fixed tetragonal optical cable 200, and finishes the light connection.
That is to say, behind the patchhole 71 with tetragonal optical cable 200 insertion screw caps 70, again to tail cover portion 12 and upper shield 20 inboard insertions, tail is overlapped portion 12 to use screw cap 70 and upper shield 20 is tightened, shown in Figure 12, the corresponding second pressurization projection 24b and the 3rd pressurization projection 24c of forming on upper shield 20 on the side of the corner, top of optical cable 200 is to optical cable 200 pressurizations.Thereby optical cable 200 firmly is fixed in tail cover portion 12 and the upper shield 20, and places plug 10 inside.
In addition, though not shown, but when fixed diameter is 0.9 optical cable, have the cylindrical shape rubber ring that openings is arranged at central portion in addition, optical cable is being inserted under the state of rubber ring, because of using rubber ring fixedly tail cover portion and upper shield, thereby also be easy to the less optical cable of fixed diameter.
