Incomparable advantage is played in environment.
Utility model content
The purpose of this utility model is to provide a kind of fast insert-pull SMA radio frequency (RF) coaxial connectors, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides following technical solution：A kind of fast insert-pull SMA RF coaxials connection
Device, including, the first shell, contact head, insulator, second housing, inner wire, described first shell one end interference fit connection the
Two shell one end, the second housing inside setting insulator, the interior insulator are led for hollow structure and in setting
Body, extends radially through setting epoxy resin between the insulator, second housing and inner wire, the contact head is set in insulator
Outside and one end be arranged on the inside of second housing.
Preferably, it is two sections of stepped cylindrical hollow structures that first shell, which is inside, outside setting cross knurled, described
The outer dia of first shell is φ 9mm.
Preferably, the material of the contact head is beryllium-bronze, and axially setting item is recessed for six slot circumference of described contact head one end
Slot.
Preferably, the outside of the inner wire is two sections of stepped cylindricals, and one end is taper, and the other end is set as cylindrical hollow
Structure.
The technique effect and advantage of the utility model：First shell is connect with socket non-threaded, and plug is with socket to inserting behaviour
Make it is convenient, fast, simple, make connector have fabulous reliability and repeatability；The outer diameter of its product is small, and contact head uses
Beryllium-bronze material splits six slots, makes it more reliable to being contacted after inserting, and insertion force is soft with withdrawal force, and makes when multicore is to inserting,
Allow the misalignment for having radial direction, improve interchangeability of the plate to plate installation or multi-core connector installation；With fast insert-pull, body
