Adopt above-mentioned plug, although can realize the coupling of two optical fiber, in use find, its water resistance is not fine, and cannot reach the classification of waterproof of IP67, thus its application scenario receives certain restriction, therefore awaits further raising.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, the plug of the water proof type fiber active linker providing a kind of water resistance good.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of plug of water proof type fiber active linker, include shell, the ferrule assembly being positioned at shell and the swivel nut be enclosed within outside shell, it is characterized in that: described shell also overlaps outward to be had the rearward end of shell storage auxiliary shell within it, described swivel nut is enclosed within this auxiliary shell and also can relatively rotates outward, and the cavity volume be formed between described shell and swivel nut for inserting for the body leading section of adapter, on described auxiliary shell, be provided with the O-ring seal for matching with the body leading section of adapter simultaneously.
Preferably, described shell is threaded by front casing and rear casing and forms, and the rearward end of front casing and rear casing are all positioned at described auxiliary shell, the middle part inwall of described front casing has described ferrule assembly restriction inward flange in the enclosure, such structure is easy to assembly, and water resistance is good.
In such scheme, outside the rearward end of described rear casing, be provided with pressure welding case, thus the effect of being fixed is played to the optical cable entered in shell.
In above-mentioned each scheme, having the annular slot for coordinating with thermoplastic sleeve pipe in the rearward end periphery of described auxiliary shell, can be connected to outside auxiliary shell securely after making thermoplastic casing deformation, to compress further optical cable.
Be preferably, the leading section periphery wall of described auxiliary shell has positive stop lug boss, the inwall of described swivel nut has a bulge loop, this bulge loop axial limiting between described positive stop lug boss and thermoplastic sleeve pipe front end, to avoid swivel nut slippage in auxiliary shell.
Preferably, the front side root of described positive stop lug boss has seal groove, and described O-ring seal is arranged in sealing groove, makes O-ring seal better with coordinating of body.
Further improve, in described seal groove, be coated with the silicon rubber bed of material, can further improve water resistance.
Compared with prior art; due to the utility model being configured with auxiliary shell; namely be equivalent to shell and carry out double layer design; thus duplicate protection has been carried out when being connected with adapter; therefore water resistance can be improved significantly, make the integrally-built classification of waterproof after connection reach IP67, and compact conformation; space hold is little, thus employing connector application scenario of the present utility model can be made wider and have better practicality.

Fig. 4 is the schematic diagram after the utility model embodiment connects with corresponding adapter.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, this plug 10 includes shell 1, be positioned at the ferrule assembly 2 of shell and the auxiliary shell 3 that is enclosed within outside shell and swivel nut 4, wherein, after auxiliary shell 3 is enclosed within shell 1, make the rearward end storage of shell 1 within it, the leading section periphery wall of this auxiliary shell 3 has positive stop lug boss 31, and the front side root of this positive stop lug boss 31 has seal groove 32, and O-ring seal 5 is arranged in sealing groove 32; The rearward end periphery of auxiliary shell 3 has the annular slot 33 coordinated with the 3rd following thermoplastic sleeve pipe 29.Swivel nut 4 is enclosed within outside this auxiliary shell 3 and also can relatively rotates, and the inwall of swivel nut 4 has a bulge loop 41, and this bulge loop 41 is axially by between positive stop lug boss 31 and the 3rd thermoplastic sleeve pipe 9 front end.Form a cavity volume between shell 1 and swivel nut 4, be used for inserting for the body leading section of adapter.In the present embodiment, shell 1 is threaded by front casing 11 and rear casing 12 and forms, and the rearward end of front casing 11 and rear casing 12 are all positioned at auxiliary shell 3, the middle part inwall of front casing 11 has ferrule assembly restriction inward flange 111 in the enclosure, is provided with pressure welding case 6 outside the rearward end of rear casing.Ferrule assembly 2 is existing conventional components, it is made up of ceramic insertion core 21, ceramic insertion core seat 22 and spring 23, the rear end of spring 23 is against on rear casing 12, the front end of spring 23 is against on ceramic insertion core seat 22, the existence of spring 23, when plug and adapter are plugged together, ceramic insertion core has certain activity, makes plug and adapter have good switching performance.
In order to play sealing, positioning action better, in seal groove 32, be coated with the silicon rubber bed of material.Sheath A is had, with in the ferrule assembly preventing from the impurity such as dust from entering assembling at the front end sleeve of ceramic insertion core 21.
During plug assembling, first ferrule assembly 2 is put into rear casing 12, more forward and backward outer casing screw is connected, then in overall press-in auxiliary shell 3, make the rearward end of front casing 11 and rear casing 12 all be tight with in auxiliary shell 3, then swivel nut 4 is enclosed within auxiliary shell 3.
In the present embodiment, plug configuration be armored optical cable 30, when this armored optical cable 30 inserts in plug casing 1, be provided with pressure welding case 6 in the rearward end of rear casing 12, this pressure welding case 6 is wrapped in the connecting portion of armored optical cable and rear casing 12 tightly, has so both guaranteed the fastness that both connect.Outside pressure welding case 6, wrap up the first thermoplastic sleeve pipe 7 again simultaneously, the second thermoplastic sleeve pipe 8 is had at the first thermoplastic sleeve pipe 7 overcoat, on the second thermoplastic sleeve pipe and auxiliary shell rearward end, cover has the 3rd thermoplastic sleeve pipe 9 again, adopt multilayer thermoplastic sleeve pipe and pressure welding case, water resistance can be improved further, and armored optical cable 30 and plug are connected firmly.
When above-mentioned plug and adapter grafting, as long as the plug 10 with armored optical cable to be inserted into the right side of adapter 20, refer to Fig. 4, now, the leading section of front casing 11 is inserted in the leading section of adapter 20, and the leading section of ferrule assembly 2 is inserted in the sleeve 201 of adapter, the leading section of the body 202 of adapter is inserted in the cavity volume formed between shell 1 and swivel nut 4, and match with O-ring seal 5, rotate swivel nut 4, make it to be connected with the threaded joints on body 202.
Because the present embodiment housing carries out double layer design, thus can improve water resistance significantly, after being connected with corresponding matching device, the classification of waterproof of connector is made to reach IP67, and compact conformation, space hold is little, and thus such connector can in multiple applications.
