Used in can apply to some there is the occasion of waterproof and dustproof requirement.
Further, the use of U-shaped sealing ring so that sealing ring can produce larger when relatively small axial decrement
Deflection, so as to provide better seal effect.
Further, as a example by the first Optical fiber plug to be first installed, the first Optical fiber plug from left to right be inserted into adapter
The left inserted terminal of housing and sleeve pipe, when plug stop section and the left stop section block on adapter housing of the first Optical fiber plug are matched somebody with somebody
During conjunction, the first Optical fiber plug is in limit on the right-right-hand limit position, and now the first Optical fiber plug coordinates with the sealing ring pushing tow of left inserted terminal, real
The sealing of existing first Optical fiber plug and fiber adapter is to inserting.Then by the second Optical fiber plug from right to left be inserted into adapter
The right inserted terminal of housing and sleeve pipe, because the optical fiber that the distance between left and right stop section is not more than first, second Optical fiber plug is inserted
For the spacing between two plug stop sections of Optical fiber plug when connecing, therefore in the optical fiber contact pins of first, second Optical fiber plug
During docking, the right stop section on adapter housing just or does not also contact with the plug stop section of the second Optical fiber plug, but
Second Optical fiber plug coordinates with the sealing ring pushing tow sealing of right inserted terminal, it is ensured that the second Optical fiber plug and fiber adapter
Sealing to insert, while also assures that the signal transmission of the optical fiber contact pins of first, second Optical fiber plug.

Specific embodiment
The implementation of fiber adapter is for example shown in Fig. 1 ~ 7：Fiber adapter in the present embodiment is ST fiber adapter, bag
Adapter housing 1 is included, the sleeve pipe 6 that axis extends in left-right direction is provided with adapter housing 1, sleeve pipe is by ceramic material system
Into, the left end of adapter housing 1 and sleeve pipe 6 be for the first Optical fiber plug to the left inserted terminal inserted, adapter housing 1 and set
The right-hand member of pipe 6 is, to the right inserted terminal inserted, to be separately provided on left inserted terminal, right inserted terminal for the second Optical fiber plug
The sealing ring coordinated with the sealing of corresponding Optical fiber plug, the sealing ring on left inserted terminal is referred to as left sealing ring 2, close on right inserted terminal
Seal is right sealing ring 7, and the present embodiment middle left and right sealing ring is U-shaped sealing ring, and U-shaped sealing ring is a kind of end-face seal ring,
U-shaped sealing ring has notch towards being the endless groove 8 of U-shaped with corresponding Optical fiber plug direction of insertion identical cross sectional shape, also
Be the notch of the endless groove for saying left sealing ring towards the right side, the notch of the endless groove of right sealing ring is towards a left side.The left end of adapter housing 1 sets
It is equipped with for being oriented to the left guide key groove 9 for loading, the right side cell wall of left guide key groove for the guiding key block on the first Optical fiber plug
Constitute and coordinate to limit the first Optical fiber plug 11 towards moving right the limit for the block of guiding key block 12 with the first Optical fiber plug
Left stop section 13, the right side of the guiding key block 12 of the first Optical fiber plug constitutes the plug stop section of the first Optical fiber plug.It is suitable
The right-hand member of orchestration housing 1 is provided with for being oriented to the right guide key groove 10 for loading for the guiding key block on the second Optical fiber plug, right
The left side cell wall of guide key groove is constituted and coordinated to limit the second optical fiber for the block of guiding key block 14 with the second Optical fiber plug
Plug 15 constitutes the second optical fiber towards the right stop section 16 for moving left the limit, the left side of the guiding key block 14 of the second Optical fiber plug
The plug stop section of plug, the distance between left stop section 13, right stop section 16 are inserted less than the optical fiber of first, second Optical fiber plug
For the spacing between two plug stop sections of Optical fiber plug when connecing, left and right sealing ring respectively with corresponding Optical fiber plug pushing tow
Sealing coordinates.Figure middle term 4 represents clamp nut；Item 5 represents shell fragments；Item 3 represents the gland being fixed to sleeve pipe 6.
The now use to this fiber adapter as a example by first installing the first Optical fiber plug is illustrated, when using, by first
The left end of fiber adapter is arrived in Optical fiber plug inserting from left to right, in the guiding key block and adapter housing of the first Optical fiber plug
Left guide key groove be oriented to and coordinate, until the guiding key block of the first Optical fiber plug is withstood on the right side cell wall of left guide key groove, this
When the first Optical fiber plug and left inserted terminal on sealing ring pushing tow seal and coordinate.Then by the second Optical fiber plug from right to left insert
The right-hand member of fiber adapter is attached to, until the ferrule end-face pair of the optical fiber contact pins of the second Optical fiber plug and the first Optical fiber plug
Connect, now the guiding key block of the second Optical fiber plug is not contacted with the left side cell wall of right guide key groove, and the sealing ring of right inserted terminal is
Sealing is realized through being deformed by the second Optical fiber plug pushing tow.Reason is similar to when second Optical fiber plug is first installed.
In other embodiments of the invention, sealing ring can also be other end-face seal rings in addition to U-shaped sealing ring,
Such as V-shaped seal ring or common faced washer；Sealing ring can also be the O-ring seal of side face seal form；It is left and right
Two plugs of Optical fiber plug when the optical fiber contact pins that the distance between stop section can also be equal to first, second Optical fiber plug are docked
Spacing between stop section；When fiber adapter is applied in equipment enclosure, equipment enclosure inside need not be sealed, because
This need to set sealing ring on fiber adapter inserted terminal；Left guide key groove can not also set, now left stop section
Can be made up of the block being arranged in adapter inner walls, can now be provided for avoiding gear on the first Optical fiber plug
The escape groove of block, the front end face of the first Optical fiber plug is used to be sealed with sealing ring pushing tow and coordinates, and block then with a left side for escape groove
The cooperation of side channel wall block moves right the limit to limit the court of the first Optical fiber plug；Fiber adapter can also be SC, FC etc. other
The fiber adapter of form.
