WATERPROOF OPTICAL FIBER CONNECTOR AND OUTDOOR COMMUNICATION DEVICE

A waterproof optical fibre connector includes a flange (20) and a terminal connector (30). The terminal connector (30) includes an outer casing (31), an inner casing (32), an optical fibre (33) and a connecting component (34) coupled with the optical fibre. The inner casing (32) is tubular for housing the optical fibre (33) and the connecting component (34). The outer casing (31) is tubular for housing the inner casing (32). The inner casing (32) includes a body (321) and a waterproof clip (322) connected to a back end of the body (321) and made of elastic material. The optical fibre (33) passes through the waterproof clip (322). The tail of the inner wall of the outer casing (31) tapers from the front to the back, pressing the waterproof clip (322) inwards such that the waterproof clip (322) and the optical fibre (33) are fixed together. At least one first protrusion (212) is provided on the inner surface of the front end of the sleeve (21) of the flange (20), and the front end of the body (321) of the inner casing (32) bears against the first protrusion (212). The waterproof optical fibre connector can be compatible with optical modules having different features. An outdoor communication device includes the waterproof optical fibre connector.
