The series of SMB products are that one kind push the locking type joining , it has small, light, electric performance a fine characteristic easy to use, Suitable for joining the coaxial cable of the radio frequency to use in the radio equipment and radio frequency loop of the electron tube instrument.
SMB系列同軸連接器是一種微型連接器，它得名于（SubMiniature B/微型B類）。同SMA（SubMiniature A/微型A類）一樣，它產(chǎn)生于十九世紀(jì)六十年代。SMB連接器的界面特別適合于電纜RG316/U和RG178/U.
SMB系列采用的彈夾外套式設(shè)計，它的連接方式采用推入式（snap-on）,接插及分離快速可靠。由于SMB系列連接器采用的連接方式以及它的小體積的特點，它適合高密度安裝。
SMB系列連接器適用于無線電設(shè)備和電子儀器的高頻回路中連接射頻同軸電纜。

（二）銅
銅是鋅合金中主要添加元素之一，銅加入到鋅合金中一方面固熔于η相和β相中，固熔強化了基體，另一方面含量到一定時合金中形成富銅的金屬間化合物（銅、鋅為基體的固熔體ε相（硬相）彌散分布于合金組織中，因而使合金的機械性能尤其是耐磨性能得到提高，銅還能提高合金的抗蠕變強度和抗腐蝕的能力。
Mini 75 ohm SMB :
Being a semi-precision, subminiature device that provides low cost connecting and broadbａnd performance with low reflection DC to 2 GHz combined with high quality,the 75 ohm impedance Mini-SMB,was designed to be intermateable with standard SMB connectors, thereby retaining its small size for high package density applications (the standard 75 ohm SMB is larger). They are available in a broad variety of mounting styles and brass body types, and various cable attachment sizes.
It’s well suited for data /video acquisition and transmission.
75 ohm SMB :
75 ohm SMB is an ideal choice for applications where low signal distortion is required such as computer, video and high speed data transfer. The "snap-on" coupling interface offers ease of installation and removal in high package density designs.
