Abstract
The invention discloses a radio frequency coaxial electric connector with a double sealing structure. The radio frequency coaxial electric connector comprises a plug and a socket, and is characterized in that a first sealing groove is formed in a conductor outside the socket; a second sealing groove is formed in an inner step; a third sealing groove is formed in a conductor outside the plug; sealing rings are respectively arranged inside each sealing groove; the plug is inserted and combined with the socket; screwed sealing caps are used for extruding the first sealing ring and the third sealing ring respectively to form first sealing of the connector; and the insertion and combination of the conductor outside the socket and the conductor outside the plug are used for extruding the second sealing ring to form second sealing of the connector. The first sealing ring is circular, and a sealing ring with a b-shaped cross section is formed by the circular first sealing ring and a unidirectional rectangular bulge on the excircle of the first sealing ring. Compared with the prior art, the radio frequency coaxial electric connector has the advantages of simple structure, reliable connection and wide application range, the waterproof sealing of the connector is well solved, the risk of sealing failure is reduced, and especially the radio frequency coaxial electric connector can be used in relatively severe environments with heavy water vapor or dust.
Description
Technical field
The present invention relates to radio frequency (RF) coaxial connector technical field, especially a kind of radio frequency coaxial electric connector with double sealing structure.
Background technology
At present, the communications industry develops the radio frequency (RF) coaxial connector that some have quick locking structure, although preferably resolve fast lock between two linkage units and be separated, but waterproof sealing performance is poor, environment cannot be used in more severe, as larger in the gaseous state of connector outside, liquid material pressure, or the place that the dust of connector outside is more serious.
Patent PCT/CN2014/072054 discloses a kind of radio frequency (RF) coaxial connector, this patented technology is in order to solve the waterproof sealing function of connector, employing arranges two sealing rings, one sealing ring is arranged in the seal groove on socket outer conductor, another sealing ring is arranged in the seal groove on plug outer conductor, after plug and socket plug together, the inwall at sealing cap two extrudes a sealing ring and another sealing ring respectively, realizes the sealing of connector.
Although above-mentioned public technology achieves fast lock between two linkage units and is separated, and the substance hermetically-sealed construction by arranging between two linkage units, solve the waterproof sealing function of connector, but the reliability of this substance hermetically-sealed construction is poor, the scope of application is very restricted, and especially cannot meet the higher environment for use of waterproof sealing requirement.
Summary of the invention
The object of the invention is a kind of radio frequency coaxial electric connector with double sealing structure designed for the deficiencies in the prior art, adopt the double sealing structure on socket outer conductor, improve the sealing property of electric connector, structure is simple, easy for installation, connects reliable, the scope of application is wide, preferably resolve the waterproof sealing of connector, greatly reduce the risk of seal failure, especially can meet in steam or the more serious adverse circumstances of dust and use.
The object of the present invention is achieved like this: a kind of radio frequency coaxial electric connector with double sealing structure, comprise by plug outer conductor, 3rd sealing ring, sealing cap, plug inner conductor and pin insulator composition plug and by the first sealing ring, socket outer conductor, second sealing ring, the socket of socket inner wire and socket insulator composition, its spy is that the screw thread tail end of socket outer conductor is provided with the first seal groove, interior step is provided with the second seal groove, the tail end of plug outer conductor is provided with the 3rd seal groove, first seal groove, in second seal groove and the 3rd seal groove, the first sealing ring is set respectively, second sealing ring and the 3rd sealing ring, plug and socket plug together, the sealing cap tightened, its two ends extrude the first sealing ring and the 3rd sealing ring respectively, realize the first resealing of connector, socket outer conductor and plug outer conductor plug together extruding second sealing ring, realize the second resealing of connector.
Described first sealing ring is that the circular rectangular preiection unidirectional with its cylindrical forms the sealing ring of cross section in " b " shape.
The material that described first sealing ring, the second sealing ring and the 3rd sealing ring adopt is silicon rubber, and its shore hardness is 55 ~ 60HS.
It is simple that the present invention compared with prior art has structure, and connect reliable, the scope of application is wide, preferably resolves the waterproof sealing of connector, greatly reduces the risk of seal failure, especially can meet in steam or the more serious adverse circumstances of dust and use.
