（3）Remarkable barrier propterty and effectiveness；
This utility model radio frequency (RF) coaxial connector is differred primarily in that with BMA types, OSSP type series：
1. BMA types, OSSP type contact forms have thoroughly been reformed.
BMA types, OSSP type contact forms are mainly disadvantageous in that：
BMA types, the connection of OSSP type headstocks clasp device (elastic spring) radial direction tensioner normal pressure " shroud ring by socket
Formula " is contacted, and without axial thrust, can cause to radially wobble and axial float, and anti-vibration and impact resistance are poor；
BMA types, OSSP types headstock are plugging together one " 6 " gap (maximal clearance is 0.38mm) of formation at datum level, cause
The discontinuity of electric capacity, produces nonlinear transport, is as a result that reflection coefficient increases, and electromagnetic energy leaks, and shield effectiveness is deteriorated, electricity
Gas performance indications are not good.
2. overall dimensions are less than OSSP type series, BMA type series
This utility model radio frequency (RF) coaxial connector overall dimensions are less, more compact than OSSP type series, BMA types series, increase
Plus modularity packing density, be save installing space, reduce machine volume, alleviate weaponry and the weight of machine system,
Consumptive material is reduced there is provided a set of good solution.
The above, is only preferred embodiment of the present utility model, not makees any formal to this utility model
Restriction, although this utility model is disclosed above with preferred embodiment, but is not limited to this utility model, any ripe
Professional and technical personnel is known, in the range of without departing from technical solutions of the utility model, when in the technology using the disclosure above
Appearance is made a little change or is modified to the Equivalent embodiments of equivalent variations, as long as without departing from technical solutions of the utility model
Hold, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, still
Belong in the range of technical solutions of the utility model.
