Description

Photovoltaic connector Technical Field The utility model relates to the technical field of connectors, in particular to a photovoltaic connector. Background The photovoltaic connector is a device for carrying out detachable movable connection between optical fibers, and precisely connects two end faces of the optical fibers, so that the light energy output by an emitting optical fiber can be coupled into a receiving optical fiber to the maximum extent, and the influence on a system caused by the intervention of the light energy into an optical link is minimized, which is the basic requirement of the photovoltaic connector, and the photovoltaic connector influences the reliability and various performances of an optical transmission system to a certain extent. Through searching, china patent discloses a photovoltaic connector (CN 202404281U) which comprises a hollow female connector and a male connector, wherein the female connector comprises a female seat body and an inner pipe connected to the female seat body and extending horizontally, a plurality of clamping pins surrounding the inner pipe are further connected to the female seat body, the male connector comprises a male seat body and an inner hole connected to the male seat body and extending horizontally, the inner diameter of the inner hole is larger than the outer diameter of the inner pipe, a plurality of clamping holes surrounding the inner hole and matched with the clamping pins are further formed in the male seat body, when the photovoltaic connector is used, the female connector and the male connector are inserted in each other, the inner pipe is inserted into the inner hole, an optical fiber passes through the inner pipe, and the clamping pins on the female seat body are inserted into the clamping holes on the male seat body. However, the device still has some disadvantages in practical use, and obviously, the photovoltaic connector adopts a fixing mode of the falcon and the clamping hole, and a single fixing point design may form a single point failure risk in a large-scale power station, and once the fixing point fails due to external force or aging of materials, the reliability of the whole connection system is directly crashed, and the risk is particularly remarkable in the large-scale photovoltaic power station.
