Complete profession system, becomes the important component in connector family.It is the indispensable crucial member of coaxial transmission system
Part.The radio frequency (RF) coaxial connector Development Techniques of the country such as American and Britain, method maintain the leading position, and design, test, uses skill at production
Art has tended to be perfect, and not only forms complete standards system, but also raw material, auxiliary material, test system, assembly tool etc.
Also it has been standardized, and carries out specialized large-scale production.
Existing radio frequency (RF) coaxial connector is divided into straight and curved formula, and often angle connector cost is relatively high, shell pair
It is poor in the locating effect of insulator, Mechanical Reliability is relatively low.
Invention content
The present invention is in view of the above-mentioned problems, disclose a kind of high-performance shell of radio frequency (RF) coaxial connector.
Specific technical solution is as follows：
A kind of high-performance shell of radio frequency (RF) coaxial connector, including shell, which is characterized in that shell structure in a ring, institute
It includes pin passage, insulation subchannel and interface channel successively to state enclosure interior from front to back, and the pin passage is in cylinder
Shape channel, the pin passage edge are provided with abducent first inclined surface, and the inclination angle A of first inclined surface is
30°；The insulation subchannel includes first passage, second channel and third channel, the first passage, second channel,
The internal diameter of triple channel successively decreases successively, and the first passage, second channel, third channel are cylindrical channel；Described first is logical
The second inclined surface is provided between road and second channel, the inclination angle of second inclined surface is 45 °；The second channel and
Third inclined surface is provided between triple channel, the inclination angle of the third inclined surface is in 60 °；It is arranged on the outer surface of the shell
There are the first concave ring and the second concave ring, the trapezoidal structure in section of first concave ring, the section of second concave ring is square
Structure.
Further, the section structure in a rectangular trapezoid of first concave ring.
In use, snap ring is set on the second concave ring；It is linked in the first concave ring using high-intensity sealing circle；Contribute to
Improve sealing performance and clamping performance；Insulator is located in interface channel when installation, outer surface of insulator and the insulator
Channel inner surface is corresponding.
Beneficial effects of the present invention are：
Using the first shell of special construction, the unique pin passage of first shell, insulation subchannel and interface channel design,
Service efficiency is high, and special insulation subchannel is designed using dual-slant face, and good locating effect can be played to insulator,
