Description
Technical field
The present invention relates to a kind of sealing structure, particularly relate to the waterproof connecting structure of a kind of radio frequency connector.
Background technology
Radio frequency connector is a kind of element being provided that electrical connection and separation function, owing to application is very extensive, thus structurally also varies, of a great variety.Hermetic seal radio frequency connector is exactly one therein, and it is mainly used in the radio system that sealed compartment and radar etc. work in the presence of a harsh environment, and air-tightness and non-oxidizability to adapter there are certain requirements.
Summary of the invention
The invention aims to the shortcoming solving exist in prior art, and the waterproof connecting structure of a kind of radio frequency connector proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of waterproof connecting structure of radio frequency connector, including shell, jack and insulator, the inner chamber adaptive with insulator it is provided with in shell, the inner chamber adaptive with jack it is provided with, in the inner chamber of jack press-in insulator, in the inner chamber of insulator press-in shell in insulator, the outer surface of described insulator and jack is provided with groove, being equiped with sealing ring in groove, described groove is trapezium structure, and the internal diameter of its upper surface is less than the diameter of sealing ring；Described sealing ring includes the medial wall interference fit of outer ring and the inner core being located in outer ring, the outer surface of inner core and outer ring, outer ring and inner core and adopts silicone rubber O-ring.
Preferably, the end of described shell is also equipped with inner wire, inner wire and jack contact.
Preferably, the inner chamber of described shell is provided with the first agnail, and the first agnail blocks insulator；Jack outer surface is provided with the second agnail fixed with insulator.
Compared with prior art, the invention has the beneficial effects as follows:
1, by arranging agnail at the inner chamber of shell and jack outer surface, make to interfix between shell, insulator and jack three, it is prevented that come off.
2, being ensure that the water resistance of radio frequency connector by sealing ring, and groove is trapezium structure, the internal diameter of its upper surface is less than the diameter of sealing ring, it is possible to block sealing ring, it is prevented that when inserting or pull out, sealing ring comes off, and affects sealing property.
3, sealing ring includes outer ring and the inner core being located in outer ring, and inner core is arranged in outer ring for reinforcing, supporting outer ring, so that outer ring is indeformable in a non-operative state.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.
With reference to Fig. 1-4, the waterproof connecting structure of a kind of radio frequency connector, including shell 1, jack 2 and insulator 3, it is provided with in shell 1 and the inner chamber of insulator 3 adaptation, being provided with in insulator 3 and the inner chamber of jack 2 adaptation, jack 2 is pressed in the inner chamber of insulator 3, and insulator 3 is pressed in the inner chamber of shell 1；The end of shell 1 is also equipped with inner wire 6, and inner wire 6 contacts with jack 2.
The inner chamber of shell 1 is provided with the first agnail 4 so that after insulator 3 loads shell 1 inner chamber, the first agnail 4 blocks insulator 3, it is prevented that insulator 3 exits；Jack 2 outer surface is provided with the second agnail 5 so that jack 2 can be fixed after loading insulator 3 inner chamber in insulator 3, by arranging the first agnail 4 and the second agnail 5 ensure that insulator 3 and jack 2 in the axial direction fixing.
The outer surface of described insulator 3 and jack 2 is provided with groove 8, is equiped with sealing ring 7 in groove 8, has been effectively ensured the water resistance of radio frequency connector.Described groove 8 is trapezium structure, and the internal diameter of its upper surface is less than the diameter of sealing ring 7, it is possible to block sealing ring 7, it is prevented that when inserting or pull out, sealing ring 7 comes off, and affects sealing property.
Described sealing ring 7 includes outer ring 71 and the inner core 72 being located in outer ring 71, and inner core 72 is arranged in outer ring 71 for reinforcing, support outer ring 71, so that outer ring 71 is indeformable in a non-operative state.The medial wall interference fit of the outer surface of inner core 72 and outer ring 71, so that outer ring 71 can be fixed by inner core 72 better.Outer ring 71 and inner core 72 adopt silicone rubber O-ring, when the pressure suffered by outer ring 71 is relatively big or installs, inner core 72 can produce certain deflection, make outer ring 71 that certain deformation also occur, so that the sealing surface of sealing ring 7 can be fitted more closely with the face of obturaging, it is achieved better seal effect.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
