Optical fiber connector and optical fiber connector assembly using the optical fiber connector

Abstract

The invention relates to an optical fiber connector and an optical fiber connector assembly using the optical fiber connector. The optical fiber connector includes a housing whose front end is a plug-in end, and an MT contact piece having a guide pin hole or a guide pin is fixed in the housing through a fixing member. The housing or the fixing part is provided with a positioning hole / positioning post for positioning and anti-rotation inserting with the positioning post / positioning hole on the adapted optical fiber connector before the guide pin hole and the guide pin are inserted. The guide pin hole / guide pin inserted into the guide pin / guide pin hole on the adapted fiber optic connector after the positioning hole and the positioning post are positioned and inserted, the diameter of the guide pin hole on the fiber optic connector / the diameter of the guide pin Larger than the hole diameter of the guide pin hole / diameter of the guide pin. The invention provides an optical fiber connector capable of realizing blind insertion and being used in a vibration and shock environment and an optical fiber connector assembly using the optical fiber connector.

Description

technical field [0001] The invention relates to an optical fiber connector and a connector assembly using the optical fiber connector. Background technique [0002] In order to achieve high-density transmission of optical signals, fiber optic connectors using MT contacts (ie, multi-channel contacts) are becoming more and more widely used. Existing fiber optic connectors using such MT contacts are disclosed in Chinese patent CN203720411U "a A kind of modular fiber optic connector", the fiber optic connector includes a plug and a socket, because the plug and the socket are compatible with each other, so the plug and the socket can also be called a fiber optic connector and an adapted fiber optic connector, the plug includes a plug housing , the socket includes a socket housing, the socket MT contact is installed in the plug housing through the jack fixing part, and the plug MT contact is installed in the socket housing through the pin fixing part, and the socket MT contact and...

AI Technical Summary

Problems solved by technology

The problem with the existing optical fiber connector is that the diameter of the guide pin is small, so it is generally impossible to achieve one-time alignment, which leads to the inability of the connector to achieve blind mating. When the guide pin and the guide pin hole are not aligned. When the plug and socket are inserted, it is likely to bend the guide pin and affect the use of the connector; in addition, only rely on the cooperation of the guide pin and the guide pin hole to prevent the radial relative movement of the plug MT contact and the socket MT contact. Vibration and shock resistance of the entire fiber optic connector is not strong, because a slight vibration and shock, vibration and shock will cause the plug MT contact and socket MT contact to have a large displacement in the radial direction, affecting The quality of signal transmission ultimately leads to the fact that the entire fiber optic connector cannot be used in harsh environments such as outdoors
