Background
With the development of optical communication technology, a large number of inter-board optical fiber connectors are used in a data center equipment cabinet to realize signal transmission between a daughter board and a backboard. In order to keep the optical module coupling end in the optical fiber connector between boards clean, a dust-proof door is often disposed at the front side of the plugging port in the connector housing to cover the internal optical module when the connector is not plugged.
For example, chinese patent No. 201380033869.X and U.S. patent No. 556,008 disclose two types of optical fiber connectors, respectively, and both of the two types of optical fiber connectors are provided therein with a flip dust-proof door, which keeps a closed state when the connectors are not plugged, and shields the front end of the optical plugging module. When the adaptive connector is plugged with the adaptive connector, the arm plate extending in the plugging direction in the adaptive connector can push and turn the dustproof door to open, so that the front end of the optical module is opened, and the optical modules of the two connectors can be coupled conveniently. After the adaptive connector is pulled out, the turnover dustproof door can automatically rotate to a closed state under the acting force of the spring.
The connector disclosed in these two documents has a flat-plate-shaped turnover dustproof door, and both doors are turned outwards when pushed open by an adaptive connector, so that in order to ensure smooth opening of the dustproof door, a certain space needs to be reserved in the plugging direction of the connector, which results in a larger plugging distance of the connector, and the length of the connector is larger, which is not suitable for the current development requirements of miniaturization and high density.
