Description
Technical field
The utility model relates to joints of optical fibre technical field, relates in particular to a kind of FC type assembled on site formula joints of optical fibre.
Background technology
The joints of optical fibre be optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it is the accurate butt joint of two end faces of optical fiber, so that being coupled to receive in the optical fiber to greatest extent, the luminous energy of launching fiber output goes, and make because it is got involved optical link and the influence that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have also influenced reliability and every performance of optical transmission system.
The joints of optical fibre can be divided into single mode, the multimode connector of common silica-based optical fibers by the difference of transmission medium, also have other as being the joints of optical fibre of transmission medium with plastic cement etc.; Can be divided into by connector version: FC, SC, ST, LC, D4, DIN, MU, MT or the like various forms.
The existing above-mentioned form joints of optical fibre are all by being inserted into optical fiber in the contact pin, after the contact pin section is ground, carry out standby or assembling, can not be in the on-the-spot directly use of assembling.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of FC type joints of optical fibre that can assemble at the scene, and it saves man-hour, and is easy to use.
For achieving the above object, the FC type assembled on site formula joints of optical fibre of the present utility model, comprise the contact pin, the outer sleeve that links to each other with adapter, the tail cover that have the optic fibre hole that passes through for optical fiber, described contact pin cooperates with outer sleeve by the suit connection shell that has intermediate throughholes thereon and links to each other, described connection shell tail end is that described tail cover is fixedly set on this double tail structure in the double tail structure that is subjected to can tighten up mutually under the external force.
Further, the tail cover is connected by screw thread with the double tail structure.
Further, be set with the dilatation portion that has with the corresponding reaming of optical fiber cable external diameter on the described contact pin, described reaming is connected with optic fibre hole, through hole, is sleeved in the dilatation portion to connect the shell front end.
Be provided with the locating piece of convex in the outer sleeve, connect shell and be provided with preposition block and rearmounted block outward, described locating piece is between preposition block and rearmounted block.
In addition, be set with dust cap on the contact pin.
Adopted technique scheme, can install this connector at the scene, by being inserted, covered wire cable connects shell through hole, the reaming of dilatation portion, optical fiber is inserted in the optic fibre hole of contact pin the most at last, the tail cover is sleeved on the double tail structure that connects the shell tail end, when screw thread is tightened, empennage is tightened up mutually, realization is firmly stuck to covered wire cable, the assembled on site of the head that achieves a butt joint; Add dust cap, prevent that lock pin is infected with dust, it is simple in structure, compact, uses, easy for installation.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is done further to describe in detail:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
By as can be known shown in Figure 1, the FC type assembled on site formula joints of optical fibre of the present utility model, comprise the contact pin 2 that has the optic fibre hole 1 that passes through for optical fiber, the outer sleeve 3 that links to each other with adapter, tail cover 4, contact pin 2 cooperates with outer sleeve 3 by the suit connection shell 6 that has intermediate throughholes 5 thereon and links to each other, connecting shell 6 tail ends is in double tail 7 structures that are subjected to can tighten up mutually under the external force, and described tail cover 4 is fixedly set on this double tail 7.Tail cover 4 is connected by screw thread 8 with double tail 7.Be set with the dilatation portion 10 that has corresponding reaming 9 with the optical fiber cable external diameter on the contact pin 2, described reaming 9 is connected with optic fibre hole 1, through hole 5, is sleeved in the dilatation portion 10 to connect shell 6 front ends.Be provided with the locating piece 11 of convex in the outer sleeve 3, connect shell 6 outer preposition block 12 and the rearmounted blocks 13 of being provided with, described locating piece 11 is between preposition block 12 and rearmounted block 13.Be set with dust cap 14 on the contact pin 2.
In use, covered wire cable is inserted connection shell through hole, the reaming of dilatation portion, optical fiber is inserted in the optic fibre hole of contact pin the most at last, the tail cover is sleeved on the double tail structure that connects the shell tail end, when screw thread is tightened, empennage is tightened up mutually, and realization is firmly stuck to covered wire cable, realizes on-the-spot assembling fast.
Above content is preferred embodiment of the present utility model, for those skilled in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
