Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a convenient to assemble is swift, and sealing reliability is good to effectively avoid steam to get into equipment, guarantee the airtight radio frequency coaxial connector of preventing that equipment used for a long time.

In order to solve the technical problem, the utility model discloses a prevent airtight radio frequency coaxial connector, including the shell with can install the inner conductor in the shell, be provided with the spacing step that is used for installing the insulator on the inner conductor, settle between shell and the inner conductor have one lean on pressing an insulator on spacing step and with No. two insulators of an insulator side by side arrangement, be provided with one between an insulator and No. two insulators and compress tightly No. two sealing washers on the inner wall of shell including conductor outlying a sealing washer and one.

The inner side edge of the inner side end of the first insulator is provided with an inner ring groove used for placing a first sealing ring, the outer side edge of the inner side end of the first insulator is provided with an outer ring groove used for placing a second sealing ring, the second insulator is pressed against the inner side end of the first insulator and compresses the first sealing ring on the periphery of the inner conductor and the second sealing ring on the inner wall of the shell.

And an elastic plug hole is formed in one end of the position-limiting step of the inner conductor.

The first sealing ring and the second sealing ring are O-shaped sealing rings.

The other end of the inner conductor extends out of the outer shell and is provided with a conductor connecting hole at the end part.

The outer side end of the first insulator is provided with a positioning boss matched with the limiting step on the inner conductor, and the positioning boss of the first insulator is tightly pressed on the limiting step of the inner conductor.

The shell is provided with a positioning step, and the outer edge of the end face of the outer side of the first insulator is limited on the positioning step.

The utility model has the advantages that:

directly settle between shell and inner conductor has two insulators, be provided with one simultaneously between two insulators respectively and compress tightly at the peripheral sealing washer of inner conductor and one compress tightly No. two sealing washers on the inner wall of shell, through this seal structure design, only need at one of them sealing washer processing go out be used for settling the annular of sealing washer can, processing is simple and the assembly mode has also obtained the change, it is swift convenient to assemble, even the part machining tolerance is great, can not play the effect because of the factor of processing with the assembly yet, sealing reliability is very good, airtight effect has been guaranteed, thereby effectively avoided steam entering equipment, guarantee equipment permanent use, still great improvement product quality and production efficiency, and the production cost is reduced.
