Abstract
The utility model discloses a high precision fiber optic attenuator, including metal casing and the collimater of setting in the metal casing both sides, the metal casing bilateral symmetry is provided with fine -tuning, and the collimater is installed on fine -tuning. The utility model relates to a rationally, be favorable to collimater and collimater connecting pipe inner room ultraviolet glue fast cure's purpose, simultaneously, can guarantee the precision of fibre optic attenuator, guarantee the fibre optic attenuator the result of use and to the requirement of precision.
Description
Technical field
The utility model belongs to a kind of high-precision optical fiber attenuator.
Background technology
Existing fibre optic attenuator comprises metal shell and collimating apparatus, metal shell both sides have collimating apparatus to connect pipe box, metal shell is connected pipe box with collimating apparatus be one-piece construction, during installation, collimating apparatus collimating apparatus being inserted metal shell both sides connects in pipe box, use ultraviolet glue hydropexis, because ultraviolet light can not through metal shell, affect curing efficiency, normal insufficient owing to solidifying, and cause the collimating apparatus angular misalignment of metal shell both sides, the precision of fibre optic attenuator can not be ensured, affect result of use and the requirement to precision.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of high-precision optical fiber attenuator, reasonable in design, be conducive to collimating apparatus and the quick-setting object of collimating apparatus connecting pipe inner room ultraviolet glue, simultaneously, the precision of fibre optic attenuator can be ensured, ensure the result of use of fibre optic attenuator and the requirement to precision.
The utility model solves the technical scheme that its technical matters adopts:
A kind of high-precision optical fiber attenuator, is characterized in that: comprise metal shell and the collimating apparatus being arranged on metal shell both sides; Described metal shell symmetria bilateralis is provided with micro-adjusting mechanism, and collimating apparatus is arranged on micro-adjusting mechanism.
As a kind of technical scheme of optimization, described micro-adjusting mechanism symmetry is arranged on metal shell; Described micro-adjusting mechanism comprises the tuning plate that axle is connected to metal shell inside, and the outboard end of tuning plate is connected with collimating apparatus; Described metal shell is provided with the fine setting actuating unit be in transmission connection with tuning plate.
As a kind of technical scheme of optimization, described fine setting actuating unit is comprised and running through and the regulating shaft be arranged on by bearing seat on metal shell, and regulating shaft has been threaded threaded block, and threaded block is fixedly mounted on tuning plate; The outboard end of described regulating shaft is connected with handle.
As a kind of technical scheme of optimization, described tuning plate is made up of transparent material, and uniform aperture in the part of stretching out metal shell at tuning plate.
Owing to have employed technique scheme, compared with prior art, the utility model is reasonable in design, be conducive to collimating apparatus and the quick-setting object of collimating apparatus connecting pipe inner room ultraviolet glue, simultaneously, the precision of fibre optic attenuator can be ensured, ensure the result of use of fibre optic attenuator and the requirement to precision.
