The requirement of present automotive industry in the aspect of the waterproof connector is more and more high, the demand is more and more big, but current on-vehicle connector only is provided with single axial waterproof construction usually or is provided with more sealing washer and just can effectively be waterproof, the reliability of this connector in the in-service use process can't be guaranteed to the waterproof connector of only single axial waterproof construction, but if be provided with more sealing washer, if one of them sealing washer is inefficacy, can lead to whole waterproof connector waterproof nature to become invalid, and the cost of manufacture of product is higher, the preparation process is comparatively complicated.

The coaxial waterproof connector comprises a shell and a coaxial line, wherein an outer conductor is arranged in the shell, the coaxial line extends into the shell, a coaxial line main body is arranged behind the outer conductor, a line core of the coaxial line extends into the outer conductor to be connected to the inner conductor in the outer conductor, and a crimping pipe used for fastening the outer conductor to the coaxial line in a compression mode is sleeved on the outer conductor. The invention uses excessive sealing rings to carry out waterproof treatment on the connector, has high cost, and can cause the waterproof failure of the whole part if one sealing ring fails.

For example, the chinese patent CN210957097U discloses an enhanced waterproof connector, which comprises a metal outer conductor and a metal inner conductor, the metal inner conductor is provided with a first groove and a second groove from outside to inside, the second rubber sealing ring is arranged in the first groove, a multi-tooth-shaped rubber sealing ring is arranged in the second groove, a first insulating medium is sleeved on the metal inner conductor, the first groove is wrapped inside, the first insulating medium is provided with the first rubber sealing ring, the second insulating medium is sleeved on the inner end of the metal inner conductor, the metal outer conductor is sleeved on the first insulating medium, the multi-tooth-shaped rubber sealing ring and the second insulating medium, and the first insulating medium, the multi-tooth rubber sealing ring and the second insulating medium are fixed, and a third groove is formed in the metal outer conductor, and a third rubber sealing ring is arranged in the third groove. When the multi-tooth sealing ring is extruded, the sealing ring is easily torn off, so that the waterproofness of the product is invalid.

Therefore, how to design a vehicle-mounted waterproof connector and an assembling method thereof can reduce the number of used sealing rings, reduce the cost, reduce the assembling process, extrude and protect the sealing rings, and effectively prevent water of a product, which is a very important thing to be solved.
