Description
Technical field
The utility model relates to a kind of guide pin and installation method thereof of MPO connector, belongs to fiber plant field.
Background technology
China is setting about the planning carrying out national optical-fiber network at present, and plan is universal fiber optic network in China, as built data center, Optical Fiber Transmission machine room, intelligent acess network, to meet the demand of people to Integrated access such as voice, video, data.MPO connector is one of data center, the most important connector of optical fiber machine room, meet the features such as volume required in future optical networks construction is little, density large, continue flexibly, Integrated access cost is low, along with the construction of market informationization, MPO connector will play prior effect.
Traditional stainless steel guide pin is owing to adopting annular cutting method, and no matter stainless steel guide pin is all likely bend in assembling process or in use procedure or rupture, and increases the probability of product rejection; Traditional stainless steel guide pin is owing to adopting annular cutting method, and stainless steel guide pin can rotate freely in MT contact pin inside, objectively also reduces the mandatory docking effect of product, causes product insertion loss excessive, and optical index consistance is deteriorated.
Utility model content
The guide pin of a kind of MPO connector that the utility model provides for above-mentioned deficiency and installation method thereof.
The utility model adopts following technical scheme:
The guide pin of a kind of MPO connector described in the utility model, described MPO is multi-fiber connector, and multi-fiber connector is divided into male and female, is provided with to pin pedestal in male; The multi-fiber connector of described male is provided with guide pin, and guide pin matches with guide pin pedestal and installs.
The guide pin of MPO connector described in the utility model, the top of described guide pin is provided with chamfering; Bottom is provided with grooving.
The guide pin of MPO connector described in the utility model, described grooving is two, and is parallel to each other.
The guide pin of MPO connector described in the utility model, described guide pin is stainless steel material.
The guide pin of MPO connector described in the utility model, is characterized in that described guide pin diameter is 0.6-0.7mm.
The installation method of the guide pin of MPO connector described in the utility model, step is as follows:
1), by the top of guide pin stretch in grooving, and confirm the position of guide pin grooving and pedestal draw-in groove;
2), that the plane of guide pin grooving is concordant with the breach direction of guide pin pedestal and aim at;
3), above-mentioned steps 1 is adopted)-2), another root metal guide pin is assembled in the opposite side draw-in groove of guide pin pedestal, completes the assembling of whole guide pin assembly.
Beneficial effect
The guide pin of the MPO connector that the utility model provides and installation method thereof, simple and reliable, abandon the technological deficiency of traditional stainless steel guide pin completely, both significantly product reliability was improved, again reduce the insertion loss of product, improve homogeneity of product index, there is substantial economics, achieve good effect.
Job operation is simple and reliable, difficulty of processing is little, production cost is low, be conducive to large-scale production, the more important thing is, by redesigning, improve stainless steel guide pin intensity, no matter product is in assembling process or the docking repeatedly of later stage MPO connector, reduce the damage probability of stainless steel guide pin, greatly improve the reliability of product; In addition due to plane cutting, stainless steel guide pin can not rotate after mounting, improves the mandatory alignment result of MPO connector, effectively reduces the insertion loss of product, have larger technical advantage and promotional value.
Accompanying drawing explanation
Fig. 1 is male head structure schematic diagram of the present utility model;
Fig. 2 is guide pin structural representation of the present utility model;
Fig. 3 is guide pin base construction schematic diagram of the present utility model.
In figure, 1 is MPO Male head connector; 1-1 is MT contact pin; 3 is stainless steel guide pins, and 3-1 is stainless steel guide pin top, and 3-2 is stainless steel guide pin grooving, and 4-1 is guide pin base bottom; 4-2 is guide pin draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in the figure: a kind of MPO connector stainless steel guide pin, MPO is multi-fiber connector, is divided into male 1, and containing guide pin is male, and not containing guide pin is female.
The stainless steel cylinder of to be diameters the be φ 0.6990mm of guide pin 3 described in the stainless steel guide pin of male, chamfering 3-1 is arranged at its top, jack that is convenient and MT contact pin plugs repeatedly, two parallel grooving 3-2 are arranged at bottom, main and the guide pin pedestal 4 of this stainless steel guide pin coordinates, and 4-2 in the draw-in groove that can slide into guide pin pedestal under the effect of external force easily.
A stainless steel guide pin with parallel grooving coordinates with a guide pin pedestal with draw-in groove, and this assembly method is carried out according to following steps:
1) pinch the top 3-1 of guide pin 3 on the other hand, another hand pinches the bottom 4-1 of guide pin pedestal, and confirms the position of guide pin grooving and pedestal draw-in groove;
2) the plane 3-2 of guide pin grooving is concordant with the breach direction 4-2 of guide pin pedestal and aim at, 4-2 in the draw-in groove otch 3-2 of guide pin being pressed in guide pin pedestal, hears that slight click wiping sound is seated;
3) adopt same method, another root metal guide pin is assembled in the opposite side draw-in groove of guide pin pedestal, completes the assembling of whole guide pin assembly;
Because the external diameter of stainless steel guide pin is very thin, be only φ 0.6990mm, traditional (5) adopt annular grooving, and after cutting, outside diameter of inner ring is less than φ 0.3mm, very easily will produce following three kinds of situations:
When existing guide pin embeds guide pin pedestal 4-2, because after the cutting of stainless steel annular, external diameter is comparatively thin, physical strength reduces, and existing guide pin afterbody is as easy as rolling off a log to bend, and affects merging precision;
After MPO connector plugs repeatedly, existing stainless steel guide pin afterbody equally also can be caused to bend or fracture, cause whole MPO connector product rejection;
Stainless steel guide pin due to inside be annular grooving structure, after Product Assembly under the effect of external force, stainless steel guide pin is easy to spin, in the process of MPO connector docking, reduce the mandatory alignment result of stainless steel guide pin and MT pilot hole.
