The invention discloses a novel optical cable junction box, and belongs to the technical field of communication. The novel optical cable junction box comprises a junction box body, a transmission module, a wire crimping module, and a connecting sleeve. The transmission module is arranged inside the junction box body. One end of the junction box body is provided with a rectangular through hole. The wire crimping module is arranged in the middle of the junction box body. The outer wall of the junction box body is provided with an external thread, and the inner wall of the connecting sleeve is provided with an internal thread corresponding to the external thread. The connecting sleeve is in threaded connection with the junction box body through the matching external and internal threads. Inside the junction box body, a wire needing to be connected is transmitted by the transmission module to a corresponding position and tightly clamped by the wire crimping module, so that the wire is connected more reliably and is prevented from being released due to violent shaking. When the device is not in use, the connecting sleeve can sleeve multiple connectors together, so that damage to the connectors caused by accidental collision is avoided, and the service life of the connectors is prolonged.
