The utility model discloses a kind of guiding needle mounting structures for optical fiber communication, comprising: optical fiber connector, the beneficial effects of the utility model are: through the cooperation of guiding inclined groove and the inclined surface on limiting block, automatically guide limiting block sliding compression spring in the process of optical fiber connection plug insertion, spring resets after being in position, and limiting block is clamped into limiting slot, improve assembly efficiency and connection reliability;Through the cooperation of one outer limiting plate and one positioning groove, and the cooperative limiting of the second outer limiting plate and the second positioning groove, form four-way positioning structure, effectively prevent optical fiber connection plug from rotating or horizontally deviating in bottom fixed frame, while the inside cooperation of outer connecting seat and bottom fixed frame further improves axial positioning accuracy, ensure that guiding needle body and connecting seat are accurately aligned;Through the setting of outer groove and inclined plane pull plate, inclined plane pull plate can be directly pulled from outside, drive fixed side plate, inner sliding plate and limiting block to slide synchronously, so that limiting block is separated from limiting slot.
