The invention relates to an anti-vibration hermetic filtering electric connector mainly comprising a seat shell, a left insulator, a right insulator, a grounding sheet and a plurality of filtering contact pieces. The plurality of filtering contact pieces penetrate through the grounding sheet and are fixedly connected to the inside of the seat shell by the left insulator and the right insulator, and a plurality of jaws in interference fit with the inner wall of the seat shell are uniformly arranged on the outer periphery of the grounding sheet. The filtering contact pieces contact with the seat shell by adopting the grounding sheet with peripheral jaws to form a filter network in filtering electric connection, the whole structure is simple and compact, electromagnetic interference can be effectively suppressed and favorable anti-vibration performance, sealing performance and conductance performance are achieved.
