In-position sound: the sound when the terminal assembly is in place, the pre-installation of the terminal currently relies on manual work, and there is a risk of terminal withdrawal. How to make employees better identify the terminal pre-installed in place, here is an assessment indicator that is the in-position sound. The in-position sound of the terminal assembly is higher than the ambient sound (the ambient sound level should be 30dB-50dB): 7dB before humidity, 5dB after humidity, or by Negotiated by both parties.
Terminal hole error proofing structure: When the terminal is inserted in the wrong direction, the terminal cannot be inserted into the terminal hole or the insulating support and seal are exposed outside the terminal hole. During the problem solving, we found that some terminals can be inserted into the connector in the wrong direction, and it is not easy to identify when pulled back. Therefore, the difficulty of inserting the terminals in the wrong direction should be considered when designing and selecting, so as to ensure that the terminal is inserted in the wrong direction. When the terminal is assembled, it cannot be in place.
