The invention relates to a high
return loss connector with adjustable
light attenuation. The high
return loss connector with the adjustable
light attenuation comprises a
front cover, a front light guiding
assembly, a sleeve, a thread pair
assembly, a back light guiding
assembly, a back cover, an elastic device, a jacket and a
tail cover. The thread pair assembly comprises a mark drive plate and a threaded top cover, wherein the back light guiding assembly is arranged in the matched back cover, the front light guiding assembly is arranged in the matched
front cover, the sleeve enables the front light guiding assembly and the back
light guide assembly to be coaxially assembled, the front light guiding assembly, the sleeve and the back light guiding assembly are arranged in the threaded top cover in a penetrating mode of the thread pair assembly, one end of the thread pair assembly and the back light guiding assembly are assembled through a threaded structure, the other end of the thread pair assembly contacts with the front light guiding assembly, the
front cover and the back cover are buckled, the back cover is buckled with the jacket, the elastic device is limited in a space formed by the back cover and the jacket, an opening is formed in the back cover, the opening enables the mark drive plate to show and to achieve turning, and the
tail cover is buckled with the jacket. The high
return loss connector with the adjustable
light attenuation has a characteristic of high return loss, is compact in structure, low in cost, and appropriate for volume production.
