Disclosed is a corrugated compensation connector. A cavity is formed in a shell, and a siphon opening is formed in the cavity and communicates with the cavity. An adjusting component is arranged beside the siphon opening and embedded into the siphon opening. The adjusting component is composed of an adjusting rod and a fixed sleeve, connecting ends are arranged at the two ends of the cavity, and connecting threads are arranged at the connecting ends. Due to the fact that the siphon opening is formed in the cavity, the connector can be used under working conditions of different pressure, and the use effect and the work quality of the connector can be guaranteed. The adjusting rod is arranged on the outer wall of the siphon opening, so that the pressure value of the siphon opening can be adjusted at any time, and the work effect of the connector under different pressure conditions is met.
