Technical Field

The invention relates to a connector assembly with a split dust door.

Background

The optical fiber connector is used for transmitting optical signals and has the basic principle that the coupling of the optical signals is realized by the precise butt joint of the end faces of two optical fiber ferrules, the diameter of a fiber core in a core area of the optical fiber ferrule is only 9um ~ 62.5.5 um generally, dust (common PM2.5 or PM10) can shield an optical signal path if the dust is in a contact area, IL (insertion loss) is increased, and the position of optical fiber connection is very sensitive to the dust, so that the dust prevention of the butt joint end face is very important.

When fiber connector was used for the equipment cabinet internal, because be equipped with on the equipment cabinet body and be used for radiating fan, and the fan operation time can drive the air current that carries the dust and circulate in equipment inside for near fiber connector has continuously mobile air (carries the dust), if there is the gap between the connector shell, perhaps in the twinkling of an eye of connector plug, inside the dust that mobile air carried got into the connector very easily, probably polluted the lock pin terminal surface, caused the insertion loss grow.

US patent US5716224A discloses a connector assembly with a dust-proof door, comprising a first connector as a plug and a second connector as a socket, the plugging end of the first connector being provided with a dust-proof door, which is a double door type split dust-proof door, comprising two door panels in split form. The two door plates are arranged in an up-down symmetrical mode or in a left-right symmetrical mode, the up-down symmetrical mode is used as an example, the two door plates are respectively an upper door plate and a lower door plate, and the upper portion of the upper door plate forms a driving portion and extends out of the inserting port of the first connector; the lower part forms and shelters from the part for shelter from the interface of first connector, and the juncture of upper portion and lower part articulates on first casing, still is equipped with the spring that is used for making the last door plant to close on the first casing. When the first connector and the second connector are not plugged, the upper door plate and the lower door plate cover the plugging interface of the first connector under the action of the spring, so that the dustproof effect is achieved. When the first connector and the second connector are plugged, the front end of the shell of the second connector can push the door plate to form a door plate driving part for driving the split dustproof door to be opened, so that the dustproof door is turned outwards and opened.

Although the dustproof door of above-mentioned connector can realize preventing dust, however, in order to guarantee the dustproof effect of two door plants in the above-mentioned patent, two door plants need to dock as closely as possible, consequently require higher to machining precision and assembly precision, otherwise two door plants open and close the time appear interfering easily, and if the articulated axis of door plant is located the medial surface outside of door plant or processing, assembly precision is lower, because the door plant has certain thickness, two door plants are opening the upset in-process, the medial surface of door plant can produce the amount of exercise to the opposite side motion, the problem that the door plant interfered appears equally easily. In addition, when the turnover dustproof door in the above patent is opened, the acting force of the springs connected to the two door panels needs to be overcome at the same time, so that a large driving force is needed, and the driving force is realized by the mutual insertion of the first connector and the second connector, so that a large mutual insertion force is needed during the mutual insertion.
