Electromagnetic interference exists in both radiative and conducted disturbances. Radiation interference is shielded to protect the way; conduction interference is the use of filtering protection means. In order to ensure that the transmission cable and electrical connector has good transmission characteristics and electromagnetic compatibility, the insulation conductor will be wrapped outside the thin wire braid or metal film, and then a number of insulated wire synthesis of a bundle, the outside and then wrapped insulation and shielding, This reduces EMI emissions on the cable, reduces the signal on the cable to radiate EMI, reduces crosstalk between different cables, and reduces the effects of common-mode impedance coupling over tens of kHz.

Electrical connector and shielded cable supporting the application, to ensure the minimum coupling between the external environment, the cable shield in the entire length to be complete, there is no seams or break the situation, the termination requirements are very strict, to ensure shielding Layer of the interference current directly to the metal connector with the metal shell, the shielding layer to be through the electrical connector for grounding. The end structure consists of a tailgear, an inner sleeve, a cable and a shield, and the tail hood is usually provided on the outer surface of the inner sleeve, and the tail cover and the tail of the connector are fixedly connected so that the outer diameter of the cable is not affected by the diameter of the connector Limit, according to the need to terminate any size of the cable, and the termination cable of the tensile strength is relatively high, small size and compact structure, simple structure, practical and strong.

Shielding and electrical connector termination must ensure that the connector and the chassis has a small lap resistance, the lap resistance requirements less than 5mQ, termination can be used when welding or crimping method to avoid electromagnetic leakage, termination When the shield and the rear end of the connector form a 360 degree, the closed lap.
