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(jì)，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(diǎn)，它適合高密度安裝。
SMB系列連接器適用于無(wú)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(qiáng)化了基體，另一方面含量到一定時(shí)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(jī)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(qiáng)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.
