Description

Fibre optic connector set with firmly fixed ferrule and resilient adapter
Technical field
The technical solution involves an optical connector set with a firmly fixed ferrule and resilient adapter. This configuration is used for connector mating of optical fibres.
Prior Art
Up to now the connector mating of optical fibres has been done by means of optical connector sets, which consist of two connector plugs connected in the pertinent adapter, where the correct thrust pressure of the active mating of ferrules is secured through the spring by cushioning the ferrule in the connector plugs. The connector adapters usually contain the pertinent sleeve only, rigid or longitudinally split, to ensure the correct axial alignment of the mated ferrules, without any other additional functions influencing the thrust pressure. The standard solution provides reliable mating, thanks to the correctly set ferrule spring cushioning in the ferrule plugs, but it produces some unfavourable properties of the transmission parameters due to some inaccuracies of the thrust pressure of individual plugs. For the optical connectors to meet the demands for the transmission parameters for example the insertion loss and return loss, the connector plugs must be manufactured in a very exact and rather complicated method for axial alignment and for assuring the pertinent thrust pressure. This causes an unfavourable affect upon the price of the connector plug and it also decreases to a certain extent the reliability of the mating.
At present, different types of one-fibre connectors, implemented with ferrules of nominal diameters 2,5 mm or 1,25 mm are standardised. The disadvantage of the present 2,5 mm ferrule classes is mainly the relative spatial exigency. The disadvantage of the present 1 ,25 mm ferrule class is a difficult mutual compatibility and interconnection possibility between various types, because every type needs a certain specific thrust pressure value.
Disclosure of Invention
The previous m entioned s hortcomings i n the h istory section, a re I argely e liminated by the fibre optic connector set with firmly fixed ferrule and resilient adapter. The principle of this solution is based upon the fact that it contains two connector-plugs formed by ferrules firmly fixed in ferrule flanges, which simultaneously serve as connector bodies and are terminated by fibre protection outlets. These connector plugs are inserted into mating connector adapter, provided by a loosely deposited resilient sleeve for axial a lignment of connecting ferrules. The mating connector adapter is further equipped with contracting elastic elements which provide optimum pressure upon the ferrule flanges of the connector plugs in the places of compressing areas with backstops. These backstops together with stopping connector plug faces delimit the maximum possible insertion of the connector plugs into the mating connector adapter. The lock formed within the mating connector adapter fits i nto the lock notch on the ferrule flange.
In an alternative implementation the connector set configuration contains at least one connector plug which is according to this solution inserted into the mating connector adapter, as mentioned above, and on the other side the mating connector adapter has the same configuration interface for connecting standard connectors of the MU and LC types. For connecting the ML) type connector plug, the connector adapter is on the other side provided by its internal configuration, and for connecting the LC type connector plugs this adapter is from the other side equipped by another internal configuration. The contracting elastic elements are formed by compressing springs or elastic contracting flaps, which are always used on one half of the mating connector adapter designated also for interconnecting the connector plugs of types ML) and LC.
In a multi connector application, the connector adapter is equipped by side guiding elements which enable the grouping of mating connector adapters, mounted side by side into rigid adapter blocks (matrices) of any size, which reduces the mounting space significantly.
The engineering solution proposed, is characterised by the extreme simplicity of the connector plugs, and by a very stable construction of the mating connector adapters, which enables great flexibility of the mounting configuration with space savings, and is also characterised by an easy compatibility with the existing connector types of the 1,25 mm ferrules standards.
