Description

Joints of optical fibre device

Technical field

The utility model relates to a kind of joints of optical fibre, particularly a kind of joints of optical fibre device that is applied to optical information is coupled to optical fiber.

Background technology

Along with optical fiber communication is growing, the demand of the joints of optical fibre also constantly increases, usually be equiped with optical assembly in these joints of optical fibre, it is to avoid dust or foreign matter to influence the optical property of this optical assembly, and the light signal of avoiding this optical assembly to produce directly penetrates operator's eyes damaged, and needs the inlet of these joints of optical fibre of sealing.

Please refer to Fig. 1, be the joints of optical fibre 1a of first known technology, it adopts dust plug 12a structure to realize above-mentioned purpose, when it does not dock with other optical device at connector base 11a, be assemblied in the optic fibre patchhole of this connector base 11a, to reach the effect of this optic fibre patchhole of sealing, avoid dust and foreign body intrusion.But described this dust plug of this first known technology 12a, must handle be set so that choose, with regard to the shape of this dust plug 12a, cause profile excessive because this handle is outstanding, and when these optical device such as butt joint fiber optic cables, must take this dust plug 12a apart.Therefore,, must keep properly this dust plug 12a that pulls down in the non-use age, in order to installing once more, as the not careful site of storage that selects, the danger that may cause loss or child to eat by mistake.In addition,, must pull down this dust plug 12a earlier and could check, then must load onto ability shipment behind this dust plug 12a again again carrying the light emission or receiving in the test procedure of electronic installation of semiconductor subassembly.Thus, the process of this dust plug 12a loading and unloading is loaded down with trivial details and increase the cost of assembling test.

Please refer to Fig. 2 A and Fig. 2 B, be the laterally opened joints of optical fibre 2a of second known technology, it has the spring 23a of pair of brackets in connector base 21a, the one axial region 22a as turning axle is installed, this spring 23a connects the back side of shield 24a and the medial surface of this connector base 21a, along with the insertion of fibre-optical splice 6a or extract, this shield 24a needs be fixedly arranged on this connector base 21a with another fixed support, is used for rotarily opening automatically or closing.That is, in the non-use age, this shield 24a should interior mode of supporting face close optic fibre patchhole with this connector base of butt 21a's; When desire was inserted this fibre-optical splice 6a, this fibre-optical splice 6a withstood this shield 24a and is turning axle and after this medial surface rotation of introversive this connector base 21a with above-mentioned this axial region 22a, opens this shield 24a; After extracting this fibre-optical splice 6a, by the restoring force (elastic force) of this spring 23a, this shield 24a is closed to original state automatically.

General this fibre-optical splice 6a can be provided with a pair of semicircle fillet portion of guiding usefulness in its outer rim, is located at guide channel in this optic fibre patchhole in order to cooperation, and this fibre-optical splice of guiding 6a is inserted smoothly.But these joints of optical fibre 2a of second known technology carries out the side with this shield 24a to open (horizontal type unlatching), and this guide channel is set on this shield 24a and seals the jut of this one-sided guide channel, when this fibre-optical splice 6a inserts can according to the unlatching of this shield 24a and take in to this optic fibre patchhole inboard and make this shield 24a form this one-sided guide channel so that this fibre-optical splice 6a enters in this optic fibre patchhole smoothly.But because this shield 24a invests on this fixed support with a small axial region, link with this connector base 21a and this spring 23a by this fixed support again, so this guide channel that is formed by this shield 24a is to the stationarity of this fibre-optical splice 6a, will because of itself activity and link each assembly after the combined tolerances increase reduce.In addition, the buffer substrate tablet 25a that has in described this optic fibre patchhole of these joints of optical fibre 2a of second known technology only can be to the effect of the one-sided generation controlling depth of this fibre-optical splice 6a, and the stationarity that produces this one-sided guide channel owing to this shield 24a is bad, will weaken the limitation function of this buffer substrate tablet 25a.

Please refer to Fig. 3 A and Fig. 3 B, be the last open type joints of optical fibre 3a of the 3rd known technology, it is equipped with an axial region 32a as turning axle, has the spring 33a of pair of brackets in connector base 31a, each front of this spring 33a all connects the back side of shield 34a and the interior top of this connector base 31a, along with the insertion of this fibre-optical splice 6a or extract, this shield 34a rotarily opens automatically or closes.In other words, in the non-use age, this shield 34a closes this optic fibre patchhole in the interior mode of supporting face of this connector base of butt 31a; When desire was inserted this fibre-optical splice 6a, this fibre-optical splice 6a withstood this shield 34a and is turning axle and after the inner rotation of this connector base 31a with above-mentioned this axial region 32a, opens this shield 34a; After extracting this fibre-optical splice 6a, by the restoring force (elastic force) of this spring 33a, this shield 34a is closed to original state automatically.

When inserting this fibre-optical splice 6a, to increase the weight of the load of this axial region 32a, may cause this axial region 32a impaired, and for avoiding this axial region 32a impaired because of above-mentioned burden, must adopt the robust material of hard metal system to constitute this axial region 32a and increase material cost, metal this axial region 32a installs this spring 33a in the mode that runs through, and must be embedded on this shield 34a, to finish the shield assembly of setting up this spring 33a, therefore not only time-consuming but also require great effort in assembling.

Please refer to shown in Figure 4, be the last open type joints of optical fibre 4a of the 4th known technology, it is equipped with a leaf spring 43a, has the shield 44a of an axial region 42a in connector base 41a, these joints of optical fibre 3a with the 3rd known technology, along with the insertion of this fibre-optical splice 6a or extract, this shield 44a rotates up to open or close automatically.

This leaf spring 43a also will increase the weight of the load of this axial region 42a and reduce its life-span with the 3rd known technology.

Please refer to Fig. 5, be the bottom-open type joints of optical fibre 5a of the 5th known technology, it is as elasticity shield 54a with an elastic body in connector base 51a, be conigenous the moving restoring force that closes to original state with the elastomeric products that this elasticity shield 54a itself has, along with the insertion of this fibre-optical splice 6a or extract, this elasticity shield 54a opens or closes after swing-in rotates automatically.These joints of optical fibre 5a is with the sealing guide channel with the area that increases this elasticity shield 54a, this guide channel can't extend to form along the rear direction of this optic fibre patchhole, can only near the inlet of this optic fibre patchhole, form, make that this fibre-optical splice 6a can't be according to the guiding of this guide channel and firmly insert, and can't reach good light with this optical assembly and combine; Wherein, this elasticity shield 54a will be because of bending along with this fibre-optical splice 6a enters, and it is easy to generate elastic fatigue in the bending place, and can't reply closed condition and lose effect.

Simultaneously, above-mentioned the 3rd known technology, the 4th known technology, and the 5th known technology all can't limit the insertion depth of this fibre-optical splice 6a, may make the surface of fiber end face and this optical assembly produce contact friction, and cause scratch to produce and the defeated light signal strength of reduction institute tendency to develop, and then influence system's erroneous judgement signal.
