Specific embodiment
The implementation of fiber adapter is for example shown in Fig. 1 ~ 7: the fiber adapter in the present embodiment is ST fiber adapter, packet
Adapter shell 1 is included, the casing 6 that axis extends in left-right direction is provided in adapter shell 1, casing is by ceramic material system
At, the left end of adapter shell 1 and casing 6 be for the first Optical fiber plug to slotting left inserted terminal, adapter shell 1 and set
The right end of pipe 6 is for slotting right inserted terminal, being separately provided on left inserted terminal, right inserted terminal with the second Optical fiber plug
The sealing ring of cooperation is sealed with corresponding Optical fiber plug, the sealing ring on left inserted terminal is known 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 endless groove 8 of the notch towards cross sectional shape identical with corresponding Optical fiber plug direction of insertion for U-shaped, also
It is to say the notch of the endless groove of 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 shell 1 is set
It is equipped with the left guide key groove 9 for being packed into for the guiding key block guiding on the first Optical fiber plug, the right side cell wall of left guide key groove
It constitutes for cooperating with 12 block of guiding key block of the first Optical fiber plug to limit the first Optical fiber plug 11 towards moving right the limit
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 end of orchestration shell 1 is provided with the right guide key groove 10 for being packed into for the guiding key block guiding on the second Optical fiber plug, right
The left side cell wall of guide key groove is constituted for cooperating with 14 block of guiding key block of the second Optical fiber plug to limit the second optical fiber
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 the first, second Optical fiber plug
For spacing when connecing between the plug stop section of two Optical fiber plugs, left and right sealing ring respectively with corresponding Optical fiber plug pushing tow
Sealing cooperation.Figure middle term 4 indicates fastening nut；Item 5 indicates elastic slices；Item 3 indicates the pressing sleeve that casing 6 is fixed.
Now the use of this fiber adapter is illustrated for the first Optical fiber plug is first installed, in use, by first
The left end of fiber adapter is arrived in the inserting of Optical fiber plug from left to right, in the guiding key block of the first Optical fiber plug and adapter shell
Left guide key groove be oriented to cooperation, 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 cooperate.Then by the second Optical fiber plug from right to left insert
It is attached to the right end of fiber adapter, until the optical fiber contact pins of the second Optical fiber plug and the ferrule end-face pair of the first Optical fiber plug
It connects, the guiding key block of the second Optical fiber plug is not contacted with the left side cell wall of right guide key groove at this time, and the sealing ring of right inserted terminal is
It realizes and seals through being deformed by the second Optical fiber plug pushing tow.Reason is similar when second Optical fiber plug is first installed.
In other embodiments of the invention, sealing ring is also possible to 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 circumferential surface seal form；It is left and right
The plug of two Optical fiber plugs when the distance between stop section can also be equal to the optical fiber contact pins docking of the first, second Optical fiber plug
Spacing between stop section；When fiber adapter is applied in equipment enclosure, do not need to be sealed inside equipment enclosure, because
Sealing ring need to be arranged on an inserted terminal of fiber adapter in this；Left guide key groove can not also be set, at this time left stop section
It can be made of, can be arranged on the first Optical fiber plug at this time for avoiding gear the block being set in adapter inner walls
The escape groove of block, the front end face of the first Optical fiber plug, which is used to seal with sealing ring pushing tow, to be cooperated, and block then with a left side for escape groove
The cooperation of side channel wall block moves right the limit with the court for limiting the first Optical fiber plug；Fiber adapter can also be that SC, FC etc. are other
The fiber adapter of form.
