Drawings

Fig. 1 is a cross-sectional view of an RF radio frequency coaxial connector.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the RF radio frequency coaxial connector of the present application, including contact pin 1, insulator 2, first shell 3, second shell 4, bush 5, fastener 6, swivel nut 7, snap ring 8 and sealing

washer

9, 1 outer surface parcel of contact pin has insulator 2, and insulator 2 is provided with anti-skidding barb with the 1 junction of contact pin, the shell can be divided into first shell 3 and second shell 4, and be provided with bush 5 and fastener 6 in first shell 3 and the second shell 4, first shell 3 left end is connected with swivel nut 7, and installs snap ring 8 and sealing washer 9 in the swivel nut 7.

The contact pin 1 is made of copper, the copper forming performance is good, the strength and the ductility of the material are integrated, the strength is moderate, the mechanical property, the definition of the strength and the ductility and the yield strength are realized, the connection mode of the contact pin 1 and the insulator 2 is movably connected, the contact pin 1 can rotate according to the actual condition, but cannot fall off

The insulator 2 is made of polytetrafluoroethylene Teflon or PTFE, which is commonly called "plastic king" and is a high molecular compound formed by polymerizing tetrafluoroethylene, and has excellent chemical stability, corrosion resistance, sealing property, high lubrication non-adhesiveness, electric insulation property and good ageing resistance. Used as engineering plastics and can be made into polytetrafluoroethylene tubes, rods, belts, plates, films and the like. The material is generally applied to corrosion-resistant pipelines, containers, pumps, valves, radar manufacturing equipment, high-frequency communication equipment, radio equipment and the like with higher performance requirements.

First shell 3 all is provided with anti-skidding screw thread with 4 surfaces of second shell, and the barb phase-match of 1 surface of contact pin and insulator 2, the barb can effectually let contact pin 1 fix in insulator 2, and insulator 2 can wrap up contact pin 1 completely, has guaranteed contact pin 1's stability.

First shell 3 and swivel nut 7 are threaded connection, also can easily install in rainy day, have improved the installation effectiveness of this connector, and this connector is provided with waterproof sealing washer, and waterproof performance improves greatly, is favorable to the steady operation of this connector.

The snap ring 8 is a C-shaped snap ring and is embedded in a groove formed in the shell 3 and the threaded sleeve 7. Allowing the threaded sleeve 7 to rotate freely over the housing 3.

As shown in fig. 1, when a worker needs to work with the RF coaxial connector, the worker first checks whether the RF coaxial connector is damaged obviously, and can install the RF coaxial connector after checking safety.
