An expanded beam photoelectric composite connector

Abstract

The invention discloses a beam-expanded type photoelectric composite connector. The connector comprises a base body. One end face of the base body is a smooth plane and provided with a guide column. The guide column is perpendicular to the smooth plane. The base body is provided with guide column holes and mounting holes for fixing an electrical contact piece and an optical collimator assembly. The electrical contact piece is arranged in the mounting holes through elastic components. A shell is arranged outside the base body. The base body is fixedly connected with the shell through a middle sleeve and a locking sleeve. According to the beam-expanded type photoelectric composite connector, the guide column, the guide column holes and the mounting holes are arranged on the end face of the base body, meanwhile, a connector optical path is aligned with a circuit, and an optical path collimator is attached through the smooth plane of the connector base body end face so that the problems that the end faces of optical contact pins of an existing photoelectric composite connector are prone to being polluted, and the service life is affected due to wear to the optical end face can be solved; electric contact pins and electric jacks are arranged in the mounting holes in a floating mode through the elastic components, and the alignment state of the optical path is not affected when the electric contact pins and the electric jacks are inserted.

Description

technical field [0001] The invention relates to an optical connection device, in particular to a beam expanding type photoelectric composite connector. Background technique [0002] At present, the photoelectric composite connector mainly adopts the following structure: the optical path alignment part adopts the commonly used pin floating structure, that is, the optical fiber ferrule directly contacts the precision centering through the coupling sleeve, and there is a certain gap between the optical fiber ferrule and the peripheral parts , The tail of the pin is designed with a spring to form a floating structure, which can eliminate the error of peripheral parts or the axial, radial, and angular errors caused by the contact of the electrical pin to the optical path to a certain extent; the circuit part is the electrical pin commonly used in electrical connectors Structure with electrical jacks. [0003] The existing photoelectric composite connector structure mainly has th...
