Abstract
The utility model relates to field fiber, discloses a kind of joints of optical fibre, it is characterized in that, the lock pin tailstock of the described joints of optical fibre is designed to six groove tailstocks.Adopt this technology to regulate more accurate, improve the effect of connector docking.
Description
Technical field
The utility model relates to field fiber, the joints of optical fibre of particularly a kind of optimization.
Background technology
In current optical fiber telecommunications system, the joints of optical fibre are a kind of indispensable links, be widely used in optical fiber to optical fiber, optical fiber to equipment, optical fiber to instrument etc.
Connector is by the docking of two fiber end faces precision, luminous energy is coupled receptions to greatest extent, minimizing loss; Different manufacturers produce connector docking time can produce different effects, interchangeability becomes particularly important, and improving the method that generally adopts of interchangeability is " adjusting KEY " and select better lock pin bore concentricity.
Wherein, lock pin can be rotated in " adjusting KEY " process and find best lock pin position, then make marks on the lock pin tailstock of correspondence position, using the KEY position of this position as connector.If each connector passes through this step, when connectors all in theory docks, the angle of lock pin is all consistent.Therefore can improve the effect of docking, the interchangeability between different connector also just improves.
The SC joints of optical fibre the most common in the market comprise housing, inside casing, lock pin and lock pin tailstock and spring and stop collar.Lock pin tailstock is designed to the tailstock of four grooves, and inside casing comprises small boss, and during assembling, the groove of lock pin tailstock matches with the small boss of inside casing, so when adjusting KEY, only have at most 4 angles (direction) to rotate, each rotational angle is changed to 90 degree.
Summary of the invention
For tune KEY scheme mentioned above, the object of the utility model embodiment is the joints of optical fibre providing a kind of optimization, and the lock pin tailstock of the joints of optical fibre is designed to six groove tailstocks, regulates more accurate, improves the effect of connector docking.
A kind of joints of optical fibre that the utility model embodiment provides, the lock pin tailstock of the described joints of optical fibre is designed to six groove tailstocks.
Further, the described joints of optical fibre also comprise the inside casing be connected with described lock pin tailstock, are provided with at least one for the boss suitable with the groove of described lock pin tailstock inside described inside casing.
Further, the described joints of optical fibre also comprise housing, lock pin, spring and stop collar, and described housing, inside casing, lock pin, lock pin tailstock, spring are connected successively with stop collar.
Alternatively, the described joints of optical fibre are the SC joints of optical fibre or the FC joints of optical fibre.
Therefore, application the present embodiment technical scheme, the lock pin tailstock of the joints of optical fibre is changed into six grooves by four grooves, four groove adjusting angles only have 90 degree, and six groove adjusting angles are 60 degree, adjust in KEY process and have 6 position angles, add 2 position angles, regulate more accurate, improve the effect of connector docking.And therefore the width of each groove can not narrow, still can be suitable for the standard of current industry universal, cost increases seldom, is applicable to volume production.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
embodiment:
For the SC joints of optical fibre the most common in the market, as shown in Figure 1, comprise and connect housing 10, inside casing 20, lock pin 30, lock pin tailstock 40 and spring 50 and stop collar 60 successively, as shown in Figure 2, wherein lock pin tailstock 40 is designed to the tailstock of four grooves 41, as shown in Figure 3, two boss 21 are provided with in the inside casing 20 of the SC joints of optical fibre, during assembling, the groove 41 of lock pin tailstock 40 matches with the boss 21 of inside casing 20, so when adjusting KEY, only have at most 4 angles (direction) to rotate, each rotational angle is changed to 90 degree.
The present embodiment provides a kind of SC joints of optical fibre of optimization, as shown in Figure 4, the lock pin tailstock 70 of the described SC joints of optical fibre is designed to six grooves 71, at least one is provided with for the boss 21 suitable with the groove 71 of described lock pin tailstock 70 inside described inside casing 20, for example, as shown in Figure 3, inside casing 20 is provided with two boss 21 in can being, during assembling, the groove 71 of lock pin tailstock 70 matches with the boss 21 of inside casing 20, so when adjusting KEY, have 6 angles (direction) to rotate, each rotational angle is changed to 60 degree.And in six grooves 71 of described lock pin tailstock 70, therefore the width of each groove can not narrow, consistent with the width of groove during four grooves, still can be suitable for the standard of current industry universal, and other loose mail all need not be changed, cost increases seldom, is applicable to volume production.
Therefore, change the lock pin tailstock of the SC joints of optical fibre into six grooves by four grooves, adjust in KEY process and have 6 position angles, add 2 position angles, regulate more accurate, improve the effect of connector docking.
In like manner, this programme is applicable to the FC joints of optical fibre or other connector too, the lock pin tailstock of the joints of optical fibre is changed into six grooves by four grooves, as shown in Figure 5, be provided with two boss 81 in the interior spiral shell 80 of the FC joints of optical fibre, described boss 81 is designed to level, during assembling, the groove 71 of lock pin tailstock 70 matches with the boss 81 of interior spiral shell 80, so when adjusting KEY, have 6 angles (direction) to rotate, each rotational angle is changed to 60 degree.And therefore the width of each groove can not narrow in six grooves 71 of described lock pin tailstock 70, consistent with the width of groove during four grooves, still can be suitable for the standard of current industry universal, and add 2 position angles, make to regulate more accurate, improve the effect of connector docking.
Above-described embodiment, does not form the restriction to this technical scheme protection domain.The amendment done within any spirit at above-mentioned embodiment and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technical scheme.
