Abstract
The utility model discloses a through-type flexible connector of a square connector (SC) or physical connection (PC) optical fiber. The through-type flexible connector of the SC or PC optical fiber comprises a ferrule assembly, a interior casing sleeve which is sleeved on the ferrule assembly and a slot, wherein a spring is arranged below the interior casing sleeve. An elastic sleeve is arranged in the slot. The front end of the elastic sleeve is packed in a cone-shaped sleeve and the periphery of the cone-shaped sleeve is packed in a check ring. By the special design of a fiber channel structure inside the connector, a coated fiber is fixed at the tail of the ferrule seat, outer sleeves of an optical cable end are fixed at different position, so the coated fiber is in a relatively free state in the outer sleeve. When the through-type flexible connector of the SC or PC optical fiber is docked with another optical fiber which is in a normal SC or PC optical fiber flexible connector, the fixed coated fiber can be guaranteed to keep the fiber stability. Insertion loss of the fiber flexible connection which is less than 0.5 dB, return loss which is more than 40 dB, and reliability all meet the requirements of the existing communication industry standards.
Description
Technical field
The utility model relates to the optical fiber technology field, and specifically a kind of fibre-optical splice of assembling is mainly used in Drop cable/optical fiber connector.
Background technology
Optical fiber is the major avenues of approach of current communication, also is the fundamental of network connection.Fiber to the home, and optical-fiber network advances the condition precedent that user terminal is present network speed-raising.Usually after the fiber entering household, need spare interface, in order to connecting with optical patchcord with equipment room.We this on-the-spot fast fibre-optical splice of assembling of SC/PC types, be applied in exactly Drop cable/optical fiber connector, can assemble at the scene and be installed in the wall box.
The through-type assembled in situ optical fiber of SC/PC that is similar to the utility model in usefulness is flexibly connected a scheme at present, is the mode with certain clamping, and the optical fiber head of well cutting is fixed in the joint lock pin, and head end is almost concordant with the front end face of lock pin.The fixed form of optical fiber, coated fiber and optical fiber head end is not separated fixing yet.
Have the shortcoming of technical scheme to be: optical fiber does not have enough lock pin tops of stretching out, and does not consider that optical fiber, coated fiber fix with the separation of optical fiber oversheath, during actual docking, causes easily optical fiber to damage, fracture, and it is unstable even failed to continue.
The utility model content
For the problems referred to above, the utility model aims to provide a kind of SC/PC optical fiber direct flow-through and is flexibly connected head, when oversheath is subject to external pull, and the impact that coated fiber can related under tension.
For realizing this technical purpose, scheme of the present utility model is: a kind of SC/PC optical fiber direct flow-through is flexibly connected head, comprises ferrule assembly, is nested with inside casing cover, wire casing on ferrule assembly, and inside casing cover below is provided with spring; Wire casing inside also is equipped with a resilient sleeve, and the resilient sleeve front end is enclosed with conical sleeve, and the resilient sleeve periphery is enclosed with stop collar.
As preferably, the resilient sleeve leading portion is the claw type structure.
As preferably, there is a housing groove that anti-skidding lines is arranged described inside casing cover outside also cover.
As preferably, the front end of described conical sleeve is provided with clip, and the clip upper end is provided with screw, and forcing screw cooperates this screw by the fixing rubber-insulated wire optical fiber of clip, wherein is reserved with the fibre-optical bending space in the wire casing; Clip also overlaps a cylindrical tail cover.
As preferably, be applicable to the family expenses optical cable without oversheath, the tail cover that a taper is arranged is directly overlapped in the outside of described conical sleeve.
The utility model is fixed on lock pin seat afterbody to coated fiber by the special design in joint internal optical fiber channel architecture, and the outer tube at different position fixed light cable end ends can make coated fiber be in relatively freely state like this in outer tube.In with the fiber alignment process in other common SCPC type fiber active linkers, the coated fiber that is fixed can guarantee that optical fiber keeps optical fiber stable.Optical cable crust fixing is for when joint lock pin pressurized shrinks back, be in the coated fiber of free state can be in the optical cable outer tube play, optical fiber can not be pushed up the gulf and do not fractureed.Insertion loss＜0.5dB and return loss＞40dB that this optical fiber is flexibly connected, and reliability all satisfies present communications industry table alignment request.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
A kind of SC/PC optical fiber direct flow-through is flexibly connected head as shown in Figure 1, comprises ferrule assembly 1, is nested with inside casing cover 3, wire casing 7 on ferrule assembly 1, and inside casing overlaps 3 belows and is provided with spring 4; Wire casing 7 inside also are equipped with a resilient sleeve 6, and resilient sleeve 6 front ends are enclosed with conical sleeve 8, and resilient sleeve 6 peripheries are enclosed with stop collar 5.Such as Fig. 2, resilient sleeve 6 leading portions are the claw type structure, can fix the optical fiber of multi-thickness.There is a housing groove 3 that anti-skidding lines is arranged described inside casing cover outside also cover, and can increase friction force.
Inside cable commonly used is to comprise oversheath, and aramid fiber yarn enhancement Layer, optical fiber tight sleeve layer and optical fiber be totally 4 levels.As shown in Figure 7, when oversheath is received external broach, oversheath has relative displacement with the optical cable tight sleeve layer, during actual docking, cause easily optical fiber to damage, fracture, it is unstable even failed to continue, therefore the front end that needs coated fiber to follow the optical cable crust to separate fixing described conical sleeve 8 is provided with clip 10, clip 10 upper ends are provided with screw 9, and forcing screw cooperates this screw 9 to pass through fixedly rubber-insulated wire optical fiber of clip 10, wherein is reserved with the fibre-optical bending space in the wire casing 7; Clip 10 also overlaps a cylindrical tail cover 11.
Consider and also have a kind of inside cable also to be in daily use, it mainly is comprised of optical fiber and optical fiber tight sleeve layer two parts, there are not aramid fiber yarn enhancement Layer and oversheath, therefore the utility model has replenished the fixedly structure of crust of a kind of nothing again, following Fig. 3, it is not have the crust stationary installation, only has the coated fiber stationary installation.There is a taper tail cover 13 outside of described conical sleeve 8 directly cover.
Shown in Fig. 1,4,5,6, this SC/PC type quick coupler operation steps is as follows:
1) puts first tail cover 11
2) according to given length requirement optical cable/optical fiber is carried out pre-service, transfer to rubber-insulated wire 131, expose 133 bare fibres and 132 coated fibers.The optical cable that has crust to coat need to carry out sleeve pipe again, notices that the position of steel pipe can just be clamped by clip 10.
3) optical cable/optical fiber is inserted on the quick coupler, bare fibre 123 exposes the about 0.1-1.0mm of lock pin front end, then pushes ahead resilient sleeve 6, fixedly optical cable.
4) screw up with a wrench screw, fixedly optical cable crust.
5) shift tail cover 11 onto position.
6) outer frame set 2 is put.
The above; it only is preferred embodiment of the present utility model; not in order to limiting the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, all should be included within the protection domain of technical solutions of the utility model.
