Summary of the invention
For overcoming above shortcoming, it is a kind of simple in structure that the utility model provides, the assembling fixture of the single fiber bi-directional assembly optical filter carrier that cost is low.
For reaching above goal of the invention, the utility model provides a kind of assembling fixture of single fiber bi-directional assembly optical filter carrier, comprise: a clamp base, an anchor clamps locating piece and an anchor clamps briquetting, be positioned at described clamp base upper surface center and be provided with the location cross projection and a pair of guiding tip upwards, the location cross recess of described location cross projection and optical filter carrier base is suitable; The pilot hole that described anchor clamps locating piece is provided with and the tip that leads is suitable, and the center of this locating piece is provided with first through hole suitable with the pedestal main body; It is suitable that the center of described anchor clamps briquetting is provided with the single fiber connector mounting sleeve of second through hole and BOSA assembly.
Described first through hole is circular or square.
The position of the two guiding tips that described clamp base upper surface center is provided with is asymmetric.
Because the assembling fixture of the single fiber bi-directional assembly optical filter carrier in the said structure only needs three parts, an i.e. clamp base, an one anchor clamps locating piece and an anchor clamps briquetting, and the structure of each part is all simpler, make make less, easy to operate, promptly only need the location cross recess of optical filter carrier base is aimed at the location cross projection of clamp base, again with BOSA assembly pedestal, anchor clamps locating piece and anchor clamps briquetting are aimed in order, can finish the assembling of optical filter carrier and assembly pedestal, do not need manually to adjust repeatedly the optically-coupled position of optical filter, fully guarantee the consistance of each single fiber bi-directional assembly optical filter position, improve product optically-coupled performance and first-pass yield with this.
