Description
Technical field
The present invention relates to a kind of CMA type radio frequency (RF) coaxial connector interfaces.
Background technique
Connector is the important mating original part of system engineering, from system, subsystem, cabinet, combination, printed board to it is each can
The separate unit of replacement, thousands of connector are distributed each system and position such as the nervous system of people, are responsible for control system
The electric energy of system transmits and signal controls and transmitting.Any one connector failure all will lead to the failure of whole system engineering, and
The failure of common connector relatively mostly occurs at working interface position, so connector interface is for the performance of whole system and reliable
Property is most important.
The radio frequency (RF) coaxial connector working interface that the country uses at present has very much, and master is divided from the connection type of working interface
Have following four: 1) threaded connection type, such as SMA, TNC, N, 2.92, L27, L12, the interface of this connection type, which has, to be connected
Connect conveniently, the features such as structure is simple, be most widely used at present；2) bayonet connection type, such as BNC, C, Q9, Q6, this connection
The interface of mode has the characteristics that connect quick and radio frequency connector using earliest connection type；3) it is pushed into connecting-type, such as
SMB, MCX, SMP, BMA etc., the interface of this connection type have the characteristics that structure is simple, compact, small in size.
1988, the regulation in American army mark " MIL-STD-348A:1988 Ministry of National Defence Interface Standard radio frequency connector interface "
The structure and size at BMA type connector interface.In order to enable domestic connector and international, interworking, exchange, 2004,
The 4th research institute, information products portion and 44th Research Institute of China Electronics Technology Group Corporation, referring to American army mark MIL-STD-
348A combines and has worked out GJB5246-2004 " radio frequency connector interface ", wherein, structure to BMA type connector interface and
Size has carried out specified in more detail.
BMA type connector is that one is the floating blind plugging connectors that can reach 20GHz or more with frequency.The connector interface
By the way of spring floating, it is electric that effective solution connects machine due to caused by not coaxial connector multichannel plugs together during
Gas reduced performance and mechanical damage.The outer conductor internal diameter of its electrical path is 4.08 (nominal), and insulating supporting is non-co-planar structure.
Be developed so far, BMA type connector interface has become using a kind of very extensive floating blind plugging connector, be applied to communication,
The multiple fields such as space flight, airborne, carrier-borne.
BMA type radio frequency (RF) coaxial connector is the characteristic for guaranteeing its blindmate, and negative head is the floating structure with spring, this knot
Structure require negative head-tail be it is movable, plugging together between plate and plate can not be applied to and be separated.Secondly, floating spring connects negative head
The unavoidable increase of volume for connecing device, occupies more installation spaces, is unfavorable for improving the integrated level of product.Finally, by bullet
The strength of spring itself makes BMA male and female connectors interworking, is unfavorable for the performances such as watertight and the anti-vibration of product.
