Electrical Connector - Inspect
间歇性电气问题常常是由连接不良引起的。 依照以下检查程序检查连接器。
检查连接器是否配套。
- 确保锁环正确锁紧。
- 在 Sure Seal 连接器上确保使用锁扣。
- 确保连接器中央的螺钉紧固。
- 确保连接器引脚和插孔正确对准。
检查连接器上的导线。
- 确保导线笔直地插入连接器后部。
- 确保每条导线都正确地压接在相应的连接器接触件上。
- 确保配套的连接器接触件正确地接合。 当连接器接触件正确接合时,接触件(导线)不能轻易地从连接器体中拔出。
检查各导线的绝缘层有无刻痕或磨损的痕迹。
检查连接器有无受潮。
- 检查连接器密封件有无损坏或缺失。
- 检查导线塞有无缺失或松动。
- 检查有无未正确接入连接器的导线。
- 如果导线以一定角度接入连接器,则连接器和导线绝缘层之间可能会密封不良。
- 湿气可以通过导线绝缘层进入连接器。
检查接触件是否脏污或腐蚀。
- 只能使用棉签或软刷蘸工业酒精清洁接触件。
检查各引脚和插孔。
- 使用新的引脚和插孔检查连接器各接触件的密配合。 如果连接器能抓稳朝下的新接触件,则该新接触件可用。
