Pin component for optical fiber adaptor connector

Abstract

The invention relates to a pin component for an optical fiber adaptor connector. The pin component comprises a sheath, a front flange plate, a rear flange plate, a front pin, a rear pin, an optical cable and a fixing connection structure, wherein the front flange plate and the rear flange plate are respectively arranged at the front and rear ends of the sheath; the front pin and the rear pin are respectively assembled in the front flange plate and the rear flange plate; the optical cable is connected with the two pins; the rear flange plate and the sheath are arranged in a split mode; an optical cable installation hole which is connected with the front end of the rear pin is formed in the rear flange plate; the optical cable is arranged in the optical cable installation hole; the optical cable is inserted into an inner hole of the sheath along with the rear flange plate; and the fixing connection structure is used for connecting and fixing the rear flange plate and the sheath after the optical cable is inserted into a flange plate installation hole along with the rear flange plate. The pin component for the optical fiber adaptor connector provided by the invention is easy to manufacture and high in production efficiency.

Description

technical field [0001] The invention relates to the field of optical fiber connectors, in particular to a ferrule assembly for an optical fiber transfer connector. Background technique [0002] Because the optical fiber transfer connector needs to transfer the optical path, it needs both ends to be mated with the matching connector at the same time during use. In some occasions, the transfer connector is required to pass through the wall, that is, its two ends are respectively located Inside and outside the body, this requires the length of the internal transfer contact to be longer. In the prior art, the transfer contact of most optical fiber transfer connectors is a single ceramic ferrule. Since the ceramic ferrule is Slender structure, so the processing and assembly process of the product is extremely complicated, and the product qualification rate is low, thereby increasing the production cycle and low production efficiency. Of course, there is also a form of using stan...

[0002] Because the optical fiber transfer connector needs to transfer the optical path, it needs both ends to be mated with the matching connector at the same time during use. In some occasions, the transfer connector is required to pass through the wall, that is, its two ends are respectively located Inside and outside the body, this requires the length of the internal transfer contact to be longer. In the prior art, the transfer contact of most optical fiber transfer connectors is a single ceramic ferrule. Since the ceramic ferrule is Slender structure, so the processing and assembly process of the product is extremely complicated, and the product qualification rate is low, thus increasing the production cycle and low production efficiency

Of course, there is also a form of using standard LC ferrule parts and using molded non-metal to buckle and then make an adapter ferrule, such as "a fiber optic connector ferrule assembly" disclosed in Chinese patent CN 102411173 A. The assembly includes the sheath, the front flange and the rear flange respectively arranged at the front and rear ends of the sheath, and the pin assembly also includes the front and rear pins respectively assembled in the front and rear flanges and connecting two pins. The sheath includes the first and second half sets interlocked with each other along the radial direction of the ceramic pin, and there are glue holes on the first and second half sets. The sealing of the entire pin assembly, but the first and second half sets have a long snap-fit ​​contact surface. In specific operations, it is almost impossible to achieve a complete seal of the pin assembly, and the pass rate of the product is extremely high. low, which also makes the production efficiency of the product lower
