A wireless optical communication connector between boards

Abstract

The present invention relates to an inter-board wireless optical communication connector, which includes a plurality of transmitting ends fixed on the printed board at the daughter board and receiving ends installed on the printed board at the mother board. The receiving end includes a first The pressure plate shell and the printed board assembly of the receiving end, the printed board assembly includes a detector connected in sequence, a printed circuit board of the receiving end, a flexible PCB and a surface-mount connector; the detector is installed at the left end of the first pressure plate shell, and the receiving end The end printed circuit board is fixed outside the first pressure plate housing; the right end of the first pressure plate housing and the front end stop on the fixed frame and the baffle housing with the aspheric lens fixed in the cavity is affixed; the launch end includes the front housing and The transmitter printed board assembly, which includes a laser, a transmitter printed circuit board, a flexible PCB, and a surface-mount connector connected in sequence; an aspheric lens is fixed in the front cavity of the front housing, and the rear end A laser is installed in the cavity, one side of the rear end of the front housing is open, and the printed circuit board of the transmitting end is located at the opening.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to an inter-board wireless optical communication connector. Background technique [0002] There are two main types of commonly used fiber optic connectors: physical contact type and expanded beam connection type. The cost of the physical contact type is low, but there are still problems in terms of on-site cleanability and sensitivity to dust. Dust and other pollution have a greater impact on optical performance. In addition, the optical fiber of the physical contact type connector is in contact with the end face of the optical fiber, so When subjected to vibration, the end face of the optical fiber is constantly rubbed, which will cause damage to the end face of the optical fiber and increase the insertion loss of the connector. [0003] The beam expander connector reduces the influence of dust and other pollution on optical performance, and also reduces the friction of the but...

Problems solved by technology

[0004] In order to solve the technical problems that the existing physical contact optical fiber connector is easily polluted by dust, the installation of the beam expander connector is difficult, the lens surface is not easy to clean, and the precision of the mechanical parts is too high, the invention proposes a wireless optical communication between boards Connector
