As mentioned above, in optical fiber link slot 44a, when arranging the end of corresponding optical fiber 91,101, mutual 91,101 different of two optical fiber of xsect can be realized exactly light by the coupling cream J being charged in optical fiber link slot 44a and connect.
After the xsect arrangement and connection of these external two optical fiber 91,101, light connected with outer casing clamper 61 advances forward, pressurizes and it is fixed, to interconnective optical fiber 91,101 as shown in Figure 10.
Now, light connected with outer casing clamper 61 is when advancing, the medial surface upside of light connected with outer casing clamper 61 contacts with the teat 53 of light connected with outer casing cap 51, to light connected with outer casing cap 51 pressurization, 51 of light connected with outer casing caps are to optical fiber 91,101 pressurizations that connect in optical fiber link slot 44a.
As mentioned above, in the process to optical fiber 91,101 pressurizations, a part of the coupling cream J being charged in advance in optical fiber link slot 44a departs from optical fiber link slot 44a, and as shown in Fig. 9, the coupling cream J of disengaging is housed in coupling cream accepting groove 44c.
Therefore, from the coupling cream J departing from optical fiber link slot 44a, can not consume, but be housed in coupling cream accepting groove 44c, when optical fiber 91,101 after optical connector separates, and the coupling cream J in coupling cream accepting groove 44c can be charged in optical fiber link slot 44a again.Can prevent thus when using connector, because of the first connection of optical fiber 91,101 or again connect and the loss of the coupling cream J that causes.
After completing the arrangement and connection procedure of optical fiber 91,101, in tail cover portion 12, cover upper shield 20, re-use screw cap 70 and tighten tail cover portion 12 and upper shield 20.The sheathed part 102 of the optical cable 100 in tail cover portion 12 and upper shield 20 is because of cast projection 12b, 22 pressurizeds.
Meanwhile, optical cable 100 is fixed because of pressurization projection 24a, 24b, the 24c forming in the second cast projection 22 of upper shield 20 inner sides, and as shown in Fig. 5, the first pressurization projection 24a of central authorities is to the center upper portion position pressurization of optical cable 100; The periphery of the second pressurization projection 24b and the 3rd pressurization projection 24c and optical cable 100 is close to, to left side and the right side pressurization of optical cable 100.
Therefore, optical cable 100, because of a plurality of cast projection 12b, 22 and a plurality of pressurization projection 24a, 24b, 24c, is firmly fixed in tail cover portion 12 and upper shield 20, is placed in plug 10 inside simultaneously.
Finally, plug 10 is inserted in connector shell 80, finally complete light and connect and assemble.
When completing light connection and assembling, in process on being arranged on connecting box, optical cable 100 can be crooked, now tail cover portion 12 and upper shield 20 have the length of 50 millimeters with the connecting portion of screw cap 70, along with being shorter in length than 50 millimeters, 100, optical cable is more crooked, thereby also can install in the connecting box of small dimension.
More than explanation as shown in the figure, is the explanation of carrying out for the fixation procedure of circular optical cable 100, and the field assembling type optical connector of another embodiment of the present invention also can firmly be fixed tetragonal optical cable 200, and completes light connection.
That is to say, tetragonal optical cable 200 is inserted after the patchhole 71 of screw cap 70, to tail cover portion 12 and upper shield 20 inner sides, insert again, tail is overlapped to portion 12 to use screw cap 70 and upper shield 20 is tightened, as shown in Figure 12, corresponding the second pressurization projection 24b and the 3rd pressurization projection 24c of forming on upper shield 20 in the side of the corner, top of optical cable 200, to optical cable 200 pressurizations.Thereby optical cable 200 is firmly fixed in tail cover portion 12 and upper shield 20, and is placed in plug 10 inside.
In addition, though not shown, during the optical cable that is still 0.9 at fixed diameter, have in addition the cylindrical shape rubber ring that has openings at central portion, optical cable is being inserted under the state of rubber ring, because using rubber ring fixedly tail cover portion and upper shield, thereby be also easy to the optical cable that fixed diameter is less.
