Description

Technical Field

[0002] In the prior art, in order to detect the insertion depth of the connector terminal, an observation window is usually formed on the connector housing, through which a camera can capture the terminal in the housing, so that the insertion depth of the terminal can be calculated based on the captured image of the terminal. In order to ensure that the connector remains stationary during the capture, the connector needs to be clamped on a connector fixture, and the observation window on the connector is required to face the camera.
