Description
Technical field
The present invention relates to a kind of contactless interim aligning couplers of single-core fiber.
Background technique
Single-core fiber aligner on sale is all to be contacted with each other by two optical fiber, and pass through optical fiber matching on the market at present
Liquid realizes interim coupling effect, belongs to contact type optical fiber coupler, but needs to clear up after above-mentioned coupled modes use, time-consuming expense
Power, and have to operating environment required, it is unfavorable for construction site use.
Summary of the invention
That technical problem to be solved by the invention is to provide a kind of structures is simple, repeatedly used single-core fiber is non-contact
The interim aligning coupler of formula.
In order to solve the above technical problems, the present invention provides a kind of contactless interim aligning couplers of single-core fiber；
Including pedestal, pressure head and spherical convex lens；
The locating slot of the mirror trough for agreeing with spherical lens and two placement optical fiber is provided on pedestal, mirror trough is connected to two positioning
Slot, the centerline collineation of two locating slots, and the extended line of two positioning groove center lines passes through mirror trough, and spherical convex lens are placed
In mirror trough, pressure head is hinged on pedestal, and pressure head and base engagement grip the optical fiber being placed in two locating slots.
With such a structure, the positioning that two optical fiber is realized using pressure head and base engagement, according to spherical convex lens
Focusing principle, realize the contactless coupling of two optical fiber, realize that light loss is small, and advantage with high accuracy is not required to make therebetween
It is simple to operate with matching fluid.
Technology contents of the invention are understood in order to clearer, below couple the contactless interim alignment of this single-core fiber
Device is referred to as this coupler.
It is also set up on the pedestal of this coupler there are two fiber clamp, two fiber clamps are respectively at the two sides of pressure head；
With such a structure, fiber clamp grips optical fiber, prevents optical fiber from moving in the axial direction.
There are two compression bars for the pressure head extension of this coupler, and two compression bars are corresponding with two locating slots respectively, pressure head and pedestal
Cooperation, compression bar end is resisted against in fiber sidewall, the optical fiber being placed in two locating slots is gripped；Using such knot
After structure, compression bar end is resisted against on optical fiber, guarantees the optical fiber end alignment spherical convex lens for being put into locating slot.
The locating slot of this coupler is V-arrangement locating slot；With such a structure, the cross section structure of V-arrangement can make this coupling
Clutch adapts to the different optical fiber of diameter.
Detailed description of the invention

It is repeated).
Pressure head 2 is hinged on pedestal 1, and pressure head 2 extends there are two compression bar 21, two compression bars 21 respectively with two locating slots 11
It is corresponding.
Spherical convex lens 4 are placed in mirror trough 12.
In use, two optical fiber 5 to be tested are respectively put into the locating slot 11 of pedestal 1, optical fiber 5 is by corresponding optical fiber
Fixture 3 grips, and the end of two optical fiber 5 cooperates close to spherical convex lens 4, pressure head 2 and pedestal 1,21 end of compression bar against
In 5 side wall of optical fiber, 5 end position of optical fiber being placed in two locating slots 11 is gripped, the end face of two optical fiber 5 is all
It is directed at spherical convex lens 4.
Optical signal, other end access power meter are passed through in wherein one side optical fiber 5 of two sides fiber clamp 3, at this point, light is believed
Number by the way that optical signal is passed in another optical fiber 5 under the focussing force of spherical lens, shown by power meter.
Above-described is only one embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the principle of the present invention, several variations and modifications can also be made, these also should be regarded as belonging to this hair
Bright protection scope.
