Description
Technical field
The utility model is related to N-type interface radio frequency coaxial connector airtight constructions.
Background technology
In microwave system, radio frequency (RF) coaxial connector is a kind of essential element, wide in variety, purposes is wide, is answered extensively
For including the multiple fields such as airborne, Aeronautics and Astronautics.N-type interface air-tight seal type radio frequency (RF) coaxial connector is generally as signal
Input, output port are applied on the extension sets such as transmitter, receiver, power supply of equipment, are that one kind has that service band is wide, stays
Wave is low, the air-tight seal type radio frequency (RF) coaxial connector of the features such as low is lost, and the technologies such as sintering, welding are mostly used inside transmission channel
It is packaged, realizes hermetic seal function, it is ensured that hermetic seal (maintaining internal normal pressure, or in gas shield etc.) inside extension set.One
Aspect avoids influence of the hypobaric to extension set inside high current, high voltage, high-power device component；On the other hand it is in extension set
The three proofings in portion provide safeguard.Shell uses overall structure, material selection kovar alloy to pass through agglomerant in prior art
Skill, with inner wire sinter molding, such scheme is more suitable for the relatively small product of size.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of N-type interface radio frequency coaxial connector airtight constructions, should
Structure is suitable for the product of various sizes, and sealing effect is good, and difficulty of processing is low.
In order to solve the above technical problems, the utility model provides N-type interface radio frequency coaxial connector airtight construction, including
Cylindric and left and right trend shell, cylindric glass insulator, cylindrical inner wire；
The left side of shell is equipped with external screw thread, there is outwardly extending annular flange on right side, has left and right coaxial line successively in shell
The first hole, the second hole, third hole, the 4th hole, the 5th hole of connection, the second hole, third hole, the 4th hole, the 5th hole are circle
Hole, the diameter for setting four hole are respectively Φ 2, Φ 3, Φ 4, Φ 5, then 4 ＞ Φ of Φ, 5 ＞ Φ, 3 ＞ Φ 2, third hole are close outer
The right side of shell；
The length direction middle part of inner wire, glass insulator, circular connecting cylinder are coaxially inside and outside to be nested and passes through burning
Knot mode realizes that integrated molding, the material of connecting cylinder use kovar alloy material；
The left end of inner wire penetrates shell on the right side of shell and enters in the first hole, and the right end of inner wire is exposed in shell
Except, glass insulator, connecting cylinder specification both be sufficient to make and to be placed in third hole simultaneously, connecting cylinder and third hole close-fitting
It closes, and connecting cylinder and the hole wall in third hole are mutually welded to reach airtight conditions, the axial both sides in third hole, axial the two of connecting cylinder
Side, the axial both sides of glass insulator are corresponding concordant respectively.
For the sake of simple declaration problem, below to the airtight knot of N-type interface radio frequency coaxial connector described in the utility model
Structure is referred to as this air-tight structure.
The advantages of this air-tight structure, is that the sealing structure effect is good, and difficulty of processing is low, is suitable for various different sizes
Radio frequency (RF) coaxial connector.
