Aero-engine test lead sealing device

The invention provides an aero-engine test lead sealing device, the sealing device comprises a test lead seat, a rubber containing cylinder, a pressing cap, a rubber containing cover and a sealing ring, the rubber containing cylinder is internally provided with a filler used for sealing at high temperature, the rubber containing cylinder is of two halved cylinder structures with the same structure, and the sealing ring is arranged in the rubber containing cylinder. U-shaped grooves for bundling and fixing test wires are respectively formed in the bottom surfaces of the two split cylinder structures, and the U-shaped grooves in the two split cylinder structures are oppositely arranged. The test leads in the sealing device are dispersedly fixed in the U-shaped groove of the rubber containing cylinder, so that the assembly and disassembly processes are simple, manual operation on the test leads is reduced, and the survival rate of test points is improved; the lead sealing device has the advantages of convenience
