With the development of society and scientific and technological progress, more and more human use of electronic equipment.

The miniaturization of electronic devices, low power, multi-functional, highly reliable, more and more attention. Require miniaturization, high reliability electronic equipment essential connector. Frequency of use of electronic devices is getting higher and higher, increasing density, mutual interference between the equipment and the mutual influence is inevitable. How to reduce the impact of interference. Has become the structural design of electronic products must be considered. The main mode of the electromagnetic interference conducted interference and radiated interference. Sources of interference pulse circuits, switching circuits and industrial equipment "pollution". Conducted interference signal of the device in and out of the channel into the normal working of the device, interference devices, and radiation interference devices to send and receive ports, the exposed part of the induction into the devices, interference devices work properly. Reduce conducted interference by using a variety of filtering to eliminate common mode interference signal amplitude of the differential mode.

Overcome the radiation interference grounded shield. Resistance to many types of RF radiation interference connector shielding method. Such as: RF coaxial connectors, the outer conductor with the anti interference of radio frequency radiation performance, but not enough precision, because the outer conductor is also a path of the transmitted signal. Anti-RF radiation interference connector structure, strictly speaking, does not allow gaps or holes of open space. Radiated interference everywhere, as long as the gap frequency signal induction into or radiation out of the interference signal.

Early anti-jamming coaxial connector in order to achieve rapid separation using a bayonet connection slot is exposed, there are possiblities of gaps or holes for open space .
