Description
Technical field
The utility model relates to field of communication technology more particularly to a kind of high-performance micro coaxial radio-frequency connectors.
Background technique
Connector is to connect conductor (line) with complementary elements appropriate, realizes the electromechanical compo that circuit switches on and off,
The history of radio frequency (RF) coaxial connector development only has short decades, but because it has good broadband transmission characteristics and a variety of sides
Just connection type, make its in communication equipment, weapon system, instrument and meter and household appliances with more and more extensive.With
The continuous development of machine system and being constantly progressive for production technology, radio frequency (RF) coaxial connector is also evolving, new
The kind following period of time radio frequency (RF) coaxial connector from now on that emerges one after another will develop to following direction:
Miniaturization, micromation:
The miniaturization of machine system can not only make complete machine realize the features such as multi-functional, portable, and material can be greatly lowered
Cost, transportation cost and itself energy consumption are expected, especially to Aerospace Products, moreover it is possible to launch cost be greatly lowered.Component
Miniaturization, micromation are the preceding topics of machine system miniaturization, only use miniaturization component, are just able to achieve high-density installation,
More spaces can just be saved.If the SSMB train of radio frequency coaxial connector product occurred a few years ago is because it is with small and exquisite, tight
The connection performance of the structure and fast insert-pull gathered is largely used in the military product such as portable station, guided missile；Went out again in recent years
Showed 1.0/2.3(SAA) self-feeding type connector and MMCX, SMP(2.4mm plug-in connector) etc. connectors new varieties, be
Miniaturization, micromation product, are widely used in communication equipment of new generation.These products are able to achieve very high packing density.
High-frequency:
Broader channel space, the higher message transmission rate of realization in order to obtain, machine system working frequency is continuous
It improves.Wuhan Institute of Post and Telecommunication develop New Generation Optical terminal in part coaxial transmission microwave signal frequency reached 12GHz with
On, military communication system working frequency even more strides into millimere-wave band already, and the research of domestic weapon system is also already from 8mm wave
Section has turned to 3mm wave band.Country, which is setting about developing upper frequency limit, at present is up to the mm wave RF of 50 ~ 110GHz and coaxially connects
Connect device.
The HP company in the U.S. is just proposed the 1.0mm RF coaxial company that frequency is up to 110GHz early in the early 1990s
Device is connect, and has small lot application in its microwave test instrument；Also there are the milli of different cultivars in other internationally recognizable major companies
Metric wave radio frequency (RF) coaxial connector release, as AMP company APC2.4, APC3.5 series, OMNI company OSSP series and
SMP(0 ~ 26.5GHz of plain edition, 0 ~ 40GHz of precision) series, K series, V serial (1.85mm) etc., wherein 3.5mm,
2.4mm, K type and SMP series have formed mass production, are widely used in communication equipment, test equipment and weapon system.
In short, radio frequency (RF) coaxial connector will be rapidly developed with the development of machine system, and wave is substituted in more areas
It leads and other microwave devices, becomes the indispensable key components in microwave transmission field.
High performance miniature radio-frequency coaxial connector is not much in China's existing market occupation rate, with arriving for 5G epoch
Come, the Miniature radio-frequency connector demand for small base station, antenna and remote radio connector is also increased significantly, therefore, is needed
Domestic enterprise researches and develops Related product to meet 5G line construction needs.Antenna and base station are much arranged outdoors again, therefore,
Connector will consider its weather resistance when designing, and reliability design is added.Finally, due to which small base station and antenna are empty to installation
Between propose requirement, it is desirable that connector being capable of Fast Installation, convenient to use.
