The structure and size at BMA type connectors interface.In order that domestic connector can with international, interworking, exchange, 2004,
Research institute of information products portion the 4th and 44th Research Institute of China Electronics Technology Group Corporation, with reference to American army mark MIL-STD-
348A, combines and has worked out GJB5246-2004《Radio frequency connector interface》, wherein, structure to BMA type connectors interface and
Size has carried out specified in more detail.
BMA type connectors be it is a kind of be the floating blind plugging connector that can reach with frequency more than 20GHz.The connector interface
By the way of spring floating, effectively solve during connector multichannel is plugged together due to connecting machine electricity caused by not coaxial
Gas performance is reduced 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 connectors interface is had become using a kind of quite varied floating blind plugging connector, applied to communication,
The multiple fields such as space flight, airborne, carrier-borne.
BMA types radio frequency (RF) coaxial connector is ensures the characteristic of its blindmate, and cloudy head is the floating structure with spring, this knot
Structure requires that cloudy head-tail is movable, it is impossible to applied to plugging together with separating between plate and plate.Secondly, floating spring connects cloudy head
The unavoidable increase of volume of device is connect, more installing spaces are taken, is unfavorable for improving the integrated level of product.Finally, by bullet
The strength of spring in itself makes BMA male and female connectors interworkings, is unfavorable for the performances such as watertight and the anti-vibration of product.
