The invention discloses a cable connector box with a wireless temperature and humidity monitoring function. The cable connector box comprises a box body and a data receiving terminal. A cable winding plate, a wireless temperature and humidity measuring and sending module and a battery are arranged in the box body. The battery is arranged in a battery bin, is connected with the wireless temperature and humidity measuring and sending module through a wire and supplies power to the wireless temperature and humidity measuring and sending module. The wireless temperature and humidity measuring and sending module comprises a temperature and humidity sensor, a first MCU circuit, a first baseband processing circuit, a transmitting mixer, a power amplifier circuit and an isolation circuit, wherein the temperature and humidity sensor, the first MCU circuit, the first baseband processing circuit, the transmitting mixer, the power amplifier circuit and the isolation circuit are sequentially connected. The receiving terminal comprises a filter circuit, a low noise amplifier circuit, a receiving mixer, a second baseband processing circuit and a second MCU circuit, wherein the filter circuit, the low noise amplifier circuit, the receiving mixer, the second baseband processing circuit and the second MCU circuit are sequentially connected, and the second MCU circuit is connected with a computer. The cable connector box can be used for monitoring temperature and humidity in the cable connector box through wireless transmission, people can timely find the situation that sealing performance of a cable connector is not good or water enters the cable connector box, and the cable connector box has the advantages of being simple in structure, quick, easy and convenient to operate, low in cost and the like.
