For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of anti-loosening radio frequency (RF) coaxial connector, comprise housing, contact pin is provided with in described housing, swivel nut is provided with outside housing, wherein, described housing comprises the first housing and the second housing, it is protruding that described first shell one end is circumferentially with a circle first, second shell one end is circumferentially with circle first groove, the described first protruding and mutual fit of the first groove, described swivel nut is linked in the outer wall of described first housing and the second housing junction, insulator is provided with in the cavity that described housing and contact pin are formed, described insulator is coated on described contact pin outer wall, relatively between described insulator and the contact-making surface of the second housing be provided with spline hole, spline nail is provided with in described spline hole, described spline nail comprises spline nail head, spline nail middle part and spline nail afterbody, described spline nail head is conical structure, its cross sectional shape is equilateral triangle, described spline nail middle part is cylindrical, described spline nail afterbody cross sectional shape is isosceles trapezoid, its base angle a=45 °, described spline nail head, it is integral type structure that afterbody is followed closely with spline in spline nail middle part, described spline nail head is arranged in described insulator, described spline nail afterbody is arranged in described second housing.
An anti-loosening radio frequency (RF) coaxial connector, wherein, the other end of described first projection is provided with a circle sealing ring.
The beneficial effects of the utility model are:
This radio frequency (RF) coaxial connector structure is simple, between insulator and the contact-making surface of the second housing, be provided with spline follow closely, effectively can prevent the insulator of radio frequency (RF) coaxial connector inside from relatively rotating, prevent loosening, fail safe is well ensured, adds useful life;
Three part-structures of spline nail are arranged, and make it install resistance and reduce, spline effect increases, and not easily drops and gets loose, too increase its useful life to a certain extent;
Adopt the obtained radio frequency (RF) coaxial connector of this structure, its electric property is as follows:
1. impedance: 50 Ω
2. withstand voltage: to be not less than 2700V
