Technical field
The utility model relates to a kind of electric connector that adopts optical means transmission of signal, particularly relates to a kind of fiber optic connector assembly with a lock pin and a sleeve pipe.
Background technology
Existing fiber optic connector assembly, comprises flexible jumper and adapter; Described flexible jumper comprises connector shell, ceramic insertion core, lock pin handle, spring, set nut, locating sleeve and tail cover, and the front end of described connector shell is provided with endoporus, and one end of ceramic insertion core is fixed in lock pin handle through described endoporus crimping; Described adapter comprises the little shell of adapter, ceramic pipe and adapter shell, and the front end of described adapter shell is provided with the suitable connection-peg of outwardly and the interior hole size of described connector shell; When flexible jumper is connected with adapter plug-in mounting, the ceramic insertion core of described flexible jumper inserts in the ceramic pipe of adapter.The joints of optical fibre of this structure, although structure is simpler, the defect that exists in use unreliable, the frequent appearance of flexible jumper and being connected of adapter mutually to depart from.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple structure of passing through, and can guarantee that flexible jumper is reliable with being connected of adapter, there will not be in use the fiber optic connector assembly of break-off.
For solving the problems of the technologies described above, the utility model adopts a kind of like this fiber optic connector assembly, comprises flexible jumper and adapter; Described flexible jumper comprises connector shell, ceramic insertion core, lock pin handle, spring, set nut, locating sleeve and tail cover, the front end of described connector shell is provided with endoporus, and one end of described ceramic insertion core is fixed in described lock pin handle through described endoporus crimping; Described adapter comprises the little shell of adapter, ceramic pipe and adapter shell, and the front end of described adapter shell is provided with the suitable connection-peg of outwardly and the interior hole size of described connector shell; When plug-in mounting connects, the ceramic insertion core of described flexible jumper inserts in the ceramic pipe of described adapter, and this connector assembly also comprises a snap ring; On the endoporus wall of described connector shell, be provided with first ring connected in star, in the connection-peg outside wall surface of described adapter shell, be provided with the second annular groove, when described flexible jumper is connected with adapter plug-in mounting, described snap ring is installed in the annular space that described first ring connected in star and the second annular groove surround.
In the utility model, described snap ring is annular split ring, and its one end is tapered.
Adopt after said structure, the utlity model has following beneficial effect:
Because connector assembly of the present utility model is provided with a snap ring, this snap ring is installed in the annular space that first ring connected in star and the second annular groove surround, therefore, the utility model is by this Snap ring structure, effectively guaranteed that flexible jumper is connected with adapter reliably, there will not be the phenomenon that mutually gets loose or depart from use.
Snap ring one end of utility model is tapered, and such structure makes the plug-in mounting of flexible jumper and adapter more convenient and smooth and easy.
