A kind of plug-in and pull-off device for SMB adapter
Technical field
The present invention relates to machining tools art, particularly relate to a kind of plug-in and pull-off device for SMB adapter.
Background technology
Radio frequency (RF) coaxial connector (RF adapter) is typically considered and is installed on cable or is arranged on instrument
A kind of precision connector element, for electrical connection or the separation of transmission line.Development history at RF adapter
On occur in that SMA (Sub-Miniature-A), SMB (Sub-Miniature-B), SMC successively
(Sub-Miniature-C) miniaturized products such as, wherein, SMB is that the driving of a kind of band retainer connects
Device, volume is little, shock resistance good, it is little to take up room, and is widely used in operating frequency in the range of 0-4GHz
Communication equipment, instrument and meter and navigation system.
But, owing to sub-miniature B connector and interface are relatively fine, the sealing of SMB adapter and shock resistance etc.
All plugs to sub-miniature B connector propose the highest requirement.According to the difference of SMB model, sub-miniature B connector
Diameter range is in 0.9-5.1mm, the diameter of the more commonly used sub-miniature B connector one end less than 3mm, SMB
Connecting and have soft wire, staff cannot produce the power of inserting or pull out force by wire to sub-miniature B connector, it is difficult to will
Sub-miniature B connector inserts interface, and experiment understands, and power is inserted in the engagement of SMB adapter it is generally required to 65N, and minimum is divided
Being 9N from pull out force, due to external diameter and the bore carefully remarkable hand finger of interface of sub-miniature B connector, staff cannot be real
Show the engagement of SMB adapter connector and interface and separate.Connect if only the front end of sub-miniature B connector is slightly inserted
Mouth opening part, then can affect the electric property of SMB, even cause follow-up electrical hazard;If needing to divide
From sub-miniature B connector and interface, staff is difficult to extract sub-miniature B connector from interface (to pull out joint outer end
Connect wire).
Therefore, in the installing area of RF adapter, need a kind of plug-in and pull-off device for RF adapter of research and development badly,
Effectively carry out the engagement of RF adapter connector and interface and separate, it is ensured that stable electric property.
