SMB系列产品是一种推入锁紧式连接器，它具有体积小、重量轻、电性能优良、使用方便的特点，适用于无线电设备及电子仪器的射频回路中连接射频同轴电缆用。
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系列同轴连接器是一种微型连接器，它得名于（SubMiniature B/微型B类）。同SMA（SubMiniature A/微型A类）一样，它产生于十九世纪六十年代。SMB连接器的界面特别适合于电缆RG316/U和RG178/U.
SMB系列采用的弹夹外套式设计，它的连接方式采用推入式（snap-on）,接插及分离快速可靠。由于SMB系列连接器采用的连接方式以及它的小体积的特点，它适合高密度安装。
SMB系列连接器适用于无线电设备和电子仪器的高频回路中连接射频同轴电缆。

（二）铜
铜是锌合金中主要添加元素之一，铜加入到锌合金中一方面固熔于η相和β相中，固熔强化了基体，另一方面含量到一定时合金中形成富铜的金属间化合物（铜、锌为基体的固熔体ε相（硬相）弥散分布于合金组织中，因而使合金的机械性能尤其是耐磨性能得到提高，铜还能提高合金的抗蠕变强度和抗腐蚀的能力。
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.
