Abstract

An FC type rubber-covered cable crimping-free optical fiber connector relates to the technical field of optical communication. A dustproof cap is sleeved on an upper end of an insertion core tail seat and fixed, a spring is sleeved on a bottom end of the insertion core tail seat, the upper end of the insertion core tail seat is inserted to a lower end of a big nut, an upper end of a crimping-free tube passes through the center of a support tube and is connected with a lower end of the insertion core tail seat through extrusion, an upper end of the support tube and a lower end of a locating bolt penetrate into the center of the big nut and are connected in a locking manner through threads, a rubber-covered cable penetrates into a tail tube, a front end of the rubber-covered cable is provided with cable inner fiber, and an upper end of the tail tube is sleeved on a lower part of the crimping-free tube and fixed. The FC type rubber-covered cable crimping-free optical fiber connector can greatly shorten production hours of a rubber-covered cable jumper wire and prevent quality instability factors brought by crimping, and the connected can be prefabricated according to the length required by a user, enabling quick filed terminating to be stable and reliable.

Description

FC type rubber-insulated wire is exempted from the crimping joints of optical fibre

Technical field:

The utility model relates to the optical communication technique field, is specifically related to a kind of FC type rubber-insulated wire and exempts from the crimping joints of optical fibre.

Background technology:

Along with the continuous development of optical communication technique, the user's request bandwidth is more and more higher, optical fiber register one's residence (FTTH) become the inexorable trend of development.The quick termination mode of existing optical cable has three kinds: first kind is to adopt optical fiber matching fluid, and the ceramic insertion core preformed fibers directly docks with optical cable and optical fibres, and it is limited that its shortage point is to mate the life-span at night, is not suitable for long-term connection; Second kind is then adopted fiber cut to insert the direct fixation of ceramic insertion core, and the method is difficult to reach consistance because cutting end face and length, causes the quality of connection instability easily, the transmission loss of signal etc.; The third for utilize rapid-acting coupling at the scene with fused fiber splice, execute-in-place is comparatively complicated.And traditional connector is not suitable for the rubber-insulated wire cable, and reliability is also not strong.

The utility model content:

The purpose of this utility model provides FC type rubber-insulated wire and exempts from the crimping joints of optical fibre, it can shorten rubber-insulated wire cable wire jumper greatly and produce the quality labile factor that man-hour and crimping bring, and can make on-the-spot termination fast become reliable and stable according to customer requirements length prefabricated connector.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises dust cap 1, fastening screw 2, lock pin tailstock 3, spring 4, big nut 5, stay pipe 6, exempts from aluminium hydraulic pressed connecting pipe 7, fine 9-1 in the tail pipe 8, rubber-insulated wire cable 9, cable; Dust cap 1 overlaps to lock pin tailstock 3 upper ends to be fixed, the bottom of lock pin tailstock 3 is socketed with spring 4, lock pin tailstock 3 upper ends are inserted to the lower end of big nut 5, the upper end of exempting from aluminium hydraulic pressed connecting pipe 7 is passed stay pipe 6 centers and is connected by extruding with lock pin tailstock 3 lower ends, wear to the center of big nut 5 lower end of the upper end of stay pipe 6 and fastening screw 2, and connect by screw-threaded coupling, and rubber-insulated wire cable 9 is worn to tail pipe 8, the front end of rubber-insulated wire cable 9 is provided with fine 9-1 in the cable, and tail pipe 8 upper ends cover is fixed to exempting from aluminium hydraulic pressed connecting pipe 7 bottoms.

The described aluminium hydraulic pressed connecting pipe 7 of exempting from is of a size of 17.1mm, and through be 2.05mm, the convenient extruding with lock pin tailstock 3 lower ends is connected in its top, and warp is 3.10mm in its underpart, makes things convenient for rubber-insulated wire cable 9 normally to enter to bake glue then to fix.

The utlity model has following beneficial effect: traditional stay pipe crimping process is rejected, change the roasting glue of simpler direct adhesion into, can shorten the quality labile factor that rubber-insulated wire cable wire jumper production man-hour and crimping bring greatly, and can make on-the-spot termination fast become reliable and stable according to customer requirements length prefabricated connector.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Referring to Fig. 1, this embodiment by the following technical solutions: it comprises dust cap 1, fastening screw 2, lock pin tailstock 3, spring 4, big nut 5, stay pipe 6, exempts from aluminium hydraulic pressed connecting pipe 7, fine 9-1 in the tail pipe 8, rubber-insulated wire cable 9, cable; Dust cap 1 overlaps to lock pin tailstock 3 upper ends to be fixed, the bottom of lock pin tailstock 3 is socketed with spring 4, lock pin tailstock 3 upper ends are inserted to the lower end of big nut 5, the upper end of exempting from aluminium hydraulic pressed connecting pipe 7 is passed stay pipe 6 centers and is connected by extruding with lock pin tailstock 3 lower ends, wear to the center of big nut 5 lower end of the upper end of stay pipe 6 and fastening screw 2, and connect by screw-threaded coupling, and rubber-insulated wire cable 9 is worn to tail pipe 8, the front end of rubber-insulated wire cable 9 is provided with fine 9-1 in the cable, and tail pipe 8 upper ends cover is fixed to exempting from aluminium hydraulic pressed connecting pipe 7 bottoms.

This embodiment is inserted in lock pin tailstock 3 lower ends with spring 4, to exempt from aluminium hydraulic pressed connecting pipe 7 upper ends again passes stay pipe 6 centers and lock pin tailstock 3 bottoms and uses extruding to be connected, again big nut 5 lower ends are inserted in lock pin tailstock 3 upper ends, keep subsequently centered by the big nut 5 fastening screw 2 lower end screw threads being connected with stay pipe 6 upper end screw-threaded couplings, rubber-insulated wire cable 9 is penetrated in the tail pipe (8) subsequently, rubber-insulated wire cable 9 penetrated exempt from aluminium hydraulic pressed connecting pipe 7 times in the step, after fine 9-1 normally arrives the center of lock pin tailstock 3 in guaranteeing cable, use the optical fiber glue special to dry fixing, at last tail pipe 8 tops are inserted in and exempt from aluminium hydraulic pressed connecting pipe 7 bottoms and fix, dust cap 1 is inserted in lock pin tailstock 3 tops to be fixed.

This embodiment is rejected traditional stay pipe crimping process, change the roasting glue of simpler direct adhesion into, can shorten the quality labile factor that rubber-insulated wire cable wire jumper production man-hour and crimping bring greatly, and can make on-the-spot termination fast become reliable and stable according to customer requirements length prefabricated connector
