Abstract

In general, cable harness companies do not know or do not use EMI tapes in areas where noise occurs most. In order to prevent and reduce noise and increase shielding effectiveness, an EMI tape is used at the end of the braided shield and at a part surrounding a connector.

Description

EMI 테이프를 사용한 커넥터 노이즈 감소 및 차폐 기술{Connector noise reduction and shielding technology using EMI tape}Connector noise reduction and shielding technology using EMI tape

노이즈를 예방하기 위해서 사용되는 차폐케이블에 관한 기술로 shield cable에 관한 기술이다.It is a technology related to shielded cables used to prevent noise.

차폐(sheld)방식은 금속 호일 또는 편조물 재료를 케이블에 적용해서 전기적 노이즈나 전자기장(EMC)을 제거하는 방법을 사용하거나 내부노이즈는 접지로 빠져나가게 하고 외부노이즈는 반사하며 차단할 수 있는 방법을 사용한다.The shielding method uses a method of removing electrical noise or electromagnetic field (EMC) by applying a metal foil or braid material to the cable, or using a method that allows internal noise to escape to ground and external noise to be reflected and blocked. do.

케이블에서의 노이즈란, 신호의 전달 또는 수신을 방해하는 신호를 의미한다. 이런 노이즈는 케이블 자체 자기장이나 외부에 의해서 발생하게 된다.Noise in a cable means a signal that interferes with the transmission or reception of the signal. This noise is caused by the magnetic field or the outside of the cable itself.

이러한 노이즈를 예방하기 위해서 차폐케이블을 사용하게 된다. In order to prevent such noise, a shielded cable is used.

커넥터 노이즈 예방 효과를 높이기 위해서는 일반적으로 제조하는 방식이 아닌 EMI테이프를 사용하여 차폐 성능을 높인다.In order to increase the effect of preventing connector noise, the shielding performance is improved by using an EMI tape, not a method that is generally manufactured.

가장 노이즈를 감소 및 차폐 시킬 수 있는 방법으로 효과를 극대화 한다.Maximize the effect in the way that can reduce and shield the most noise.

일반적으로 EMI테이프를 잘 사용하지 않는다. 고주파 대역의 통신이라 EMI테이프를 붙이는 순서와 위치에 따라 노이즈의 감소 및 차폐의 성능을 좌우한다.In general, EMI tape is not used well. As it is a high frequency band communication, it reduces noise and shields performance depending on the order and location of attaching the EMI tape.

편조 쉴드가 끝나는 부분과 커넥터를 둘러싸는 부분에 EMI테이프를 붙이는데 이 부분이 가장 노이즈를 감소 및 차폐되는 것이다.EMI tape is attached to the end of the braided shield and the part surrounding the connector, which is the most reduced and shielded noise.

케이블을 제작할 때 가장 많이 발생될 수 있는 부분이 끊어진 쉴드와 커넥터의 공간에서 많이 발생된다.When the cable is manufactured, the most probable part is generated in the space of the broken shield and connector.

특히 USB3.0, HDMI, Camera Link 통신에 사용되어지는 커넥터부분에 사용되어지면 노이즈 감소와 차폐성능을 높일 수 있다.In particular, noise reduction and shielding performance can be improved when used in the connector part used for USB3.0, HDMI, and Camera Link communication.
