This, in order to improve the reliability of coaxial connector product, it is necessary to which existing dielectric fixed form is improved.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of fixed structures for coaxial connector, by outer conductor
Inside cavity groove structure is set, and corresponding boss structure is set in the outer surface of dielectric, utilizes groove above-mentioned
The inside cavity that dielectric is fixed on to outer conductor is realized in the cooperation of structure and boss, avoids the insulation inside coaxial connector
There is the risk for loosening or falling off in medium.
It realizes above-mentioned technical purpose, reaches above-mentioned technique effect, the utility model is achieved through the following technical solutions：
A kind of fixed structure for coaxial connector, including the central contact being sequentially arranged from the inside to the outside, Jie of insulating
Matter and outer conductor；
The outer wall of the central contact is bonded with the inner wall of the dielectric；
The outer wall of the dielectric is equipped with several boss being distributed along its axis direction, and boss axial cross section is in
Isosceles trapezoid shape, the fixture between waist and bottom are less than 45 degree acute angles；
The inner wall of the outer conductor is equipped with several positions, and groove corresponding with each boss, groove axial cross section are in respectively
Isosceles trapezoid shape, the fixture between waist and bottom are more than or equal to 45 degree acute angles, and groove coordinates with corresponding boss to be realized
The fixation of outer conductor and dielectric, it is ensured that groove structure is axially formed mistake with boss structure in connector in practical application
Position, it is ensured that dielectric cannot free moving in outer conductor.
Further, the cross section of the groove and boss is in isosceles trapezoid, the angle that the two passes through trapezoidal waist and bottom edge
Difference is spent, realizes the fixed function of dielectric.
Further, there are gaps between the roof of the boss and the roof of groove, it can be ensured that dielectric boss exists
Free shrink in temperature change environment does not influence the configuration state of connector.
Further, the dielectric is made of polytetrafluoroethylene (PTFE).
Further, the boss is annular, and central axes are overlapped with the central axes of central contact.
Further, the boss includes several protrusions along central contact circle distribution.
Compared with prior art, the beneficial effects of the utility model：
The utility model proposes a kind of fixed structures for coaxial connector, pass through the inside cavity setting in outer conductor
Groove structure, and corresponding boss structure is arranged in the outer surface of dielectric utilizes matching for groove structure above-mentioned and boss
Close and realize dielectric is fixed on to the inside cavity of outer conductor, avoid the dielectric inside coaxial connector exist loosen or
The risk to fall off.
