Abstract

The invention relates to an adjustable ST-type connector and an adjusting method thereof. In the ST connector in the prior art, the relative positions of the insertion core and the positioning key are fixed and cannot be adjusted, so that the insertion loss is large, and the production rejection rate is high. The invention adopts a frame sleeve and a stop ring to replace the original core inserting tail handle, the frame sleeve and the stop ring can be mutually occluded or separated, the stop ring is screwed by an adjusting special tool to drive the frame sleeve to rotate together, and 2 to 24 adjusting positions can be provided. Therefore, the central contact ratio of the connectors during butt joint is ensured, the insertion loss is greatly reduced, and the transmission efficiency of the optical fiber is improved.

Description

Regulatable ST type connecting head and method of adjustment thereof
Technical field
The present invention relates to the connector that a kind of light transmitting fiber is used, particularly a kind of regulatable ST type connecting head, and relevant method of adjustment.
Background technology
ST connector of the prior art is after assembling, and the relative position at circumferencial direction between its ceramic insertion core and the positioning key is fixed, and can not adjust.Higher as if cause inserting loss because of Concentricity tolerance, then can not be improved.Thereby the common fault of like product is in the prior art, inserts the loss height, and the quality instability is produced the rejection rate height.As everyone knows, when two connector butt joints, fibre-optic fibre core concentricity COINCIDENCE PROBLEMS has quite big influence to inserting loss, and is therefore very high to the requirement of lock pin concentricity, and this has strengthened the difficulty and the production cost of lock pin processing.
Summary of the invention
The purpose of this invention is to provide a kind of novel ST type connector, to overcome above-mentioned various shortcoming of the prior art, the insertion loss when reducing the connector butt joint is so that just can obtain very satisfied butt joint effect with the common process precision.Another object of the present invention provides a kind of method of adjustment easily, the assembling quality during with the butt joint of assurance light transmitting fiber connector.
Regulatable ST type connecting head involved in the present invention comprises that a plastic boot, gland, one are connected and fixed cover and a dirt-proof boot, it is characterized in that, be provided with the frame cover and a stop collar that can rotate around its center line, described frame overlaps an end and offers an endoporus, can insert a lock pin with suitable, the outside of its same end is formed with a flange flange; Its other end offers the endoporus that interspersed optical fiber is used.Described stop collar is suitable can be placed in described frame and to overlap an end, and props up the flange flange on it, and described flange and described stop collar are provided with engaged structure, to keep interlocking pattern by elastic parts.Like this, use special adjustment instrument to push described stop collar and stubborn revolving, relative adjustment along with stop collar and frame cover, just can find an only adjustment position by the demonstration of instrument, concentricity when making two connector butt joints reaches best requirement, thereby guarantees the best transmission of light signal.
Aforesaid regulatable ST type connecting head, it is characterized in that, offer several grooves on the described flange, and be formed with a flange on the described stop collar madial wall, the suitable flange flange that can prop up described frame cover, an end opposite with its bottom surface on the stop collar madial wall also is formed with corresponding boss, described boss suitable can with the groove fit on the described frame cover flange, and the boss of the stop collar outside is formed with corresponding chase, its suitable can cooperation with the respective bump portion of described adjustment instrument one end, so as to twist tune whole.
Aforesaid regulatable ST type connecting head is characterized in that, offer on the described flange 2 to 24 grooves (six grooves that only draw among the figure, as a reference).Like this, when using speciality tool to adjust, can select 2 to 24 position of rotation, thereby reach the optimum adjustment of lock pin concentricity.
Aforesaid regulatable ST type connecting head is characterized in that, is formed with an annular groove on the described frame cover lateral surface, in order to fix a snap ring, other is provided with a spring, and the one end is located on the described snap ring, and the other end then is located in and is sheathed on the stop collar bottom surface that described frame puts.Like this, when tool using is adjusted, push described stop collar,, stop collar can be transferred on any in six positions (can change to 2 to 24 as required), to seek only concentricity by the elasticity of spring.
Regulatable ST type connecting head involved in the present invention, it is characterized in that, the speciality tool that also comprises an adjusting usefulness, described instrument one end lateral surface is formed with knurled surface, its other end is formed with the suitable lug boss that can match with the formed chase in the described stop collar boss outside, so that bite described stop collar, and adjust.The number of described boss can be selected as required.
Method of adjustment when the invention still further relates to the butt joint of a kind of light transmitting fiber connector, its set-up procedure comprises: the position of seeking best concentricity earlier by instrument; Lug boss with described special adjustment instrument one end inserts in the corresponding chase in the described stop collar boss outside then; Pushing and throw make stop collar and frame cover break away from interlock, enter interlock again behind the optimum position.
Regulatable ST type connecting head of the present invention can be done the adjustment of 2 to 24 diverse locations, rotates gear of stop collar (as Rotate 180 ° to 15 °) at every turn, just can obtain a kind of concentric, so one has 2 to 24 positions and can select.Thereby increased the probability of lock pin centering, improved the production qualification rate of ST type connector greatly, and reduced accuracy requirement the lock pin concentricity.Test records, and when using regulatable ST type connecting head of the present invention, the UPC end face inserts the proportion of goods damageds≤0.15dB.
Below with reference to accompanying drawing, describe the structure of regulatable ST type connecting head of the present invention in detail.
