Abstract:
1. A field installable optical-fiber connector, characterized in that: it at least comprises: an optical-fiber splice sleeve, having a segment of quadrangular prism provided inside with an optical-fiber splice member containing-chamber, the quadrangular prism being provided at one of its sides with a locking slot running through the side where it is located and the inner surface of the optical-fiber splice member containing-chamber, the optical-fiber splice sleeve being provided at its end opposite to the quadrangular prism with a hole for optical-fiber ferrule, an optical-fiber channel being provided between the hole for optical-fiber ferrule and the optical-fiber splice member containing-chamber; an optical-fiber splice member, placed in the optical-fiber splice member containing-chamber, including a first half or a second half opposite to each other, the first half being provided with a longitudinal optical-fiber splice groove, the first half or the second half being provided with a rib which is matched with and protrudes from the locking slot; an optical-fiber ferrule, inserted in the hole for optical-fiber ferrule and pre-provided inside with a connecting optical-fiber, the connecting optical-fiber being located at one end inside the optical-fiber ferrule and at the other end into the optical-fiber splice groove through the optical-fiber channel, the field optical-fiber entering the optical-fiber splice groove from an opposite direction to be butt jointed with the connecting optical-fiber; and an optical-fiber splice member clamp, sleeved on the quadrangular prism, provided with a longitudinally extending locking channel including an upper part and a lower part parallel to each other, the lower part being wider than the upper part, an inner wall of the locking channel pressing the rib so that the connecting optical-fiber and the field optical-fiber are kept by the first half and the second half in the optical-fiber splice groove when the quadrangular prism is moved from the lower part to the upper part of the channel.
