The crimping connection is a permanent connection that maintains mechanical and electrical property for a long time by crimping two conductors. In this paper, we have done a basic study to decide normal or abnormal condition depending on crimping. Using PZT piezo-sensor, we have analyzed crimping waveforms according to the crimping height. And hence the normal or abnormal condition of crimping connections in real time could be decided by comparison of crimping waveforms in the cases of normal crimping, over crimping, under crimping and core omitting.

The crimping connection is a permanent connection that maintains mechanical and electrical property for a long time by crimping two conductors. In this paper, we have done a basic study to make a decision the normal or abnormal condition depending on crimping. By using PZT piezo-sensor, we have compared and analyzed crimping waveforms of abnormal conditions(core ommiting, cover biting) at the normal crimping height. And hence the normal or abnormal condition of crimping connections in real time could be determined by comparison of crimping waveforms in the cases of normal crimping, core omitting and cover biting.

The principle of crimping connection is to produce a compressive connection force between terminal and cores(wire conductor). Compressive connection force is produced by pushing each other on that stress(crimping force) of barrel by restored elastic strain after plastic deformation and the expansion force of cores' elastic stress. And resistance and tension force between terminal and cores are determined according to the condition of compressive connection force. In this study, we've found out that the adaptive height which has maximum tensile force by measuring a tensile force with a height of terminal.

The terminal and core(wire conductor) in a Harness processing is connected by putting them in a applicator by virtue of a manual operation. A normal or abnormal condition of crimping connections is nearly determined by a skilled worker. In general, a skilled worker operates a press motor with a foot switch by pressing on foot and puts a wire conductor into a press with one hand. By doing so, sufficient efficiency is not obtained by a worker. In this paper, a basic study has done to make improve an efficiency by finding the normal arrangement out as to whether a terminal and wire conductor in Harness are placed on the right position or not with a quadrant plane photo position sensor.

웨어러블 소자를 구현하기 위한 칩-섬유 접합 기술을 중심으로 전자 섬유에 대한 기술 개발 동향을 소개한다. 전자 부품을 섬유에 접합하기 위해서는 먼저 전자 부품에 전원 공급 및 전기적 신호를 주고 받기 위한 회로를 섬유에 구성해야 하며, 회로의 해상도와 밀도에 따라 전도성 실을 이용하는 자수법 또는 전도성 페이스트 등을 이용한 프린트법을 통해 구현할 수 있다. 전자 부품과 섬유를 접합하기 위해서는 솔더링, ACF/NCA, 자수법, 크림핑 등의 방법을 이용하여 영구적으로 접합하거나 후크, 자석, 지퍼 등을 이용하여 탈부착이 가능하도록 접합하는 방법이 있으며, 접합 배선의 밀도 및 용도에 따라서 단독 또는 융합하여 사용한다. 접합 이후에는 방수 등 사용환경에서의 신뢰성을 확보하기 위해 encapsulation 작업을 수행해야 하며, 현재는 PDMS 등의 폴리머를 이용한 방법이 널리 쓰이고 있다.
