Embodiment 1

[0036] like figure 1 The shown optical fiber plug mainly includes three parts: a plug 1 , a coupling socket 2 and a coupling board socket 3 .

[0037] like figure 2 As shown, the plug 1 includes plug pins 101 and a plug tailstock 102; wherein, the plug pins 101 have a length of 5mm-20mm, an outer diameter of 1.5mm-3mm, an inner diameter of 0.1mm-0.5mm, and the plug tailstock 102 The length is 10-40mm, the diameter of the outer circle is 2.5mm-5mm, and the diameter of the inner circle is 0.2mm-1.5mm; the plug pins 101 and the plug tailstock 102 are circular pipes connected coaxially, and the inner diameter of the plug pins 101 is less than The inner diameter of the plug tail base 102; the outer surface of the plug tail base 102 is provided with two symmetrically distributed positioning spherical protrusions 103, and the height of the positioning spherical protrusions 103 is 0.05mm-0.2mm.

[0038] like image 3 As shown, the coupling socket 2 is used to fix the plug tailstoc...

Embodiment 2

[0047] Due to the long distance between the converter valve and the control device and the large number of optical fibers, the optical transmission system is required to be capable of long transmission distance and high arrangement density. At present, the multi-core optical fiber used in the HVDC transmission system adopts the single-core optical fiber with low optical power attenuation and long transmission distance.

[0048] At present, fiber couplers for single-core fibers are bulky, resulting in a low arrangement density of fiber couplers in the control device. At the same time, the two ends of the optical fiber are subjected to a high potential difference. If the optical fiber plug connected to the control device is not reliably grounded, a high electrostatic charge will be induced to discharge the control device or the operator, which will greatly affect the reliable operation of the control device and the operator. Personal safety.

[0049] In addition, most of the co...

Abstract

The invention relates to the technical field of electronic devices, in particular to an optical fiber plug and an optical fiber coupler. The invention relates to an optical fiber plug, comprising a plug, a coupling socket and a coupling board socket; the plug comprises a plug pin and a plug tail; the plug pin and the plug tail are circular pipes connected coaxially. The inner diameter of the plug pin is smaller than the inner diameter of the plug tail seat; the outer surface of the plug tail seat is provided with two symmetrically distributed positioning spherical protrusions. The beneficial effects of the invention are: the overall structure of the optical fiber plug is compact, and the positioning is better and more accurate; The positioning ring groove is used to lock the positioning ball projections to ensure the stability of the plug after docking, so that the optical fiber can be accurately docked with the light source in the inner hole of the luminous tube, which greatly improves the docking accuracy and ensures the stable transmission of optical signals.
