Description
Technical field
The utility model relates to the V-type groove opening-closing structure in a kind of optical fiber quick connector.
Background technology
In recent years, because fiber-to-the-home Large scale construction, optical fiber quick connector has obtained being extensive use of, and wherein pre-buried type optical fiber quick connector uses in the majority.
The core technology of pre-buried type optical fiber quick connector is the centering of the optical fiber in pre-buried optical fiber and the optical cable.Usually, fibre diameter is 125 microns, about 9 microns of the long diameter of mould (logical light diameter).So the error of optical fiber centering must could guarantee below 0.5 micron that loss reaches below the 0.2db of permission.
Optical fiber centering all is that the mode with V-type groove increased pressure board realizes.It has simple in structure, handling ease, characteristics such as easy to operate.
And between V-type groove and the pressing plate compress and the mode of unclamping has multiple mode.A kind of be under the normality by spring compression, strut with instrument during use; Another kind is to unclamp naturally under the normality, compresses during use.
Preceding a kind of mode needs to use bigger power to strut in use, because the clamping force of spring is bigger, can produce bigger impact when the V-type groove closes up when unclamping, and causes optical fiber centering inaccurate; The back is in use a kind of because softened state is the state of nature that does not have the external force effect, can produce during repeated use strut insufficient, the situation that optical fiber can't penetrate.
Summary of the invention
The purpose of this utility model is the inaccurate phenomenon of optical fiber centering that can to produce bigger impact when the V-type groove closes up and cause in order to overcome.
The purpose of this utility model realizes as follows: the V-type groove opening-closing structure in the described novel optical fiber quick coupler, the V-type groove and the pressing plate that comprise optical fiber quick connector inside, one side has inclined plane groove, use one with the trapezoidal opener of carving piece, by sliding, realize the folding between V-type groove and pressing plate.
Described V-shaped groove is the part that an end can be fixed with ceramic contact pin, the other end is provided with optical fiber insertion guiding, there is v-depression the centre.
Described inclined plane groove is meant that V-type groove and pressing plate close up the trapezoidal groove that the back forms.
Described pressing plate is to use the opener of coupling, opens back incoming fiber optic and locking.
Good effect of the present utility model is as follows: use with the trapezoidal opener of carving piece open, closed V-type groove and briquetting, make the optical fiber after the centering avoid being impacted, guarantee the raising of accuracy of alignment, the power that is operable to of fast fibre connector is improved greatly.

Fig. 2 is the utility model decomposition texture synoptic diagram
Among the figure, 1 V-type groove, 2 pressing plates, 3 openers
4 C shape jump rings, 5 optical fiber, 6 ceramic contact pins
7 pre-buried optical fiber 8 v-depressions
Embodiment
Shown in Figure 2 as Fig. 1, in the described optical fiber quick connector, comprise V-type groove 1, an end of V-type groove 1 is inlaid with ceramic contact pin 6, is solidified with pre-buried optical fiber 5 in the ceramic contact pin 6 in advance and is embedded in the v-depression 8; The other end is provided with the guide frame that optical fiber inserts.Use can strut V-type groove 1 and pressing plate 2 with the trapezoidal opener 3 of carving piece, and the optical cable and optical fibres of opening after stripping is cut 5 inserts from an end of the guiding of V-type groove 1, in v-depression 8 zones and pre-buried optical fiber 5 centerings.Take off opener 3,, finish construction because the pressure of C shape jump ring 4 accurately is fixed on pre-buried optical fiber 7 in the v-depression 8 reliably with optical cable and optical fibres 5.
Described V-shaped groove 1 is the part that an end can be fixed with ceramic contact pin 6, the other end is provided with optical fiber insertion guiding, there is v-depression 8 centre.
It is 60 ° v-depression that described v-depression 8 is arranged on angle in the middle of the part V-type groove 1, for location, guiding and the high precision centering of the optical fiber 5 in pre-buried optical fiber 7 and the optical cable.
Described ceramic contact pin 6 is the standardized elements that cooperate with standard adapter, uses the hardening agent can being fixed therein pre-buried optical fiber 7; A needs process that exposes is ground and polishing.
Described pressing plate 2 is to use corresponding opener 3, opens back incoming fiber optic and locking.
Described opener 3 is that one side has the trapezoidal piece of carving, owing to strut the gap between V-type groove and the pressing plate.
During site operation, utilize opener to strut V-type groove and pressing plate, optical cable and optical fibres inserts the V-type groove and makes fibre ribbon little curved, depresses bonnet, and optical cable is fixed in the optical cable holder reliably, unloads opener, and putting oversheath can finish.
Above-described concrete enforcement only is preferred implementation of the present invention; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; also can do some adjustment and improvement, these also should be considered as belonging to protection scope of the present invention.
