Embodiment Construction
[0020] Hereinafter, specific embodiments of the method and apparatus for detecting the reliability of the connection of the wire harness and the terminal according to the present invention will be described in detail with reference to the accompanying drawings. Provided below are only preferred embodiments according to the present invention, and those skilled in the art can think of other ways to realize the present invention on the basis of the preferred embodiments, and the other ways also fall within the scope of the present invention .
[0021] see figure 1 , in the method for detecting the reliability of the connection of the wire harness and the terminal piece according to the present invention, a sensing step is first performed in which the pressure applied to the wire harness is sensed in real time when the wire harness and the terminal piece are connected by applying pressure. and pressure on the end fittings. While the sensed pressure is being acquired, the sensed ...

The present invention relates to a method for detecting reliability of a connection of a wire harness and a terminating member, comprising: a sensing step in which real-time sensing is performed on pressure applied to the wire harness and the terminating member when the wire harness and the terminating member are connected; a conversion step in which the sensed pressure is converted to a time-based pressure curve by taking the moment of starting pressure application as a start point; an evaluation step in which the pressure curve obtained in the conversion step is compared with a standard curve, if the deviation between the pressure value and the standard pressure value at the same time point is less than a preset threshold, it is determined that the connection is reliable; if the deviation between the pressure value and the standard pressure value at the same time point is greater than or equal to the preset threshold, it is determined that the connection is unreliable. The inventionalso relates to an apparatus for detecting the reliability of the connection of the wire harness and the terminating member. According to the present invention, it is possible to detect the terminating quality in real time so as to effectively ensure the terminating quality at the time of wire harness manufacture.
Description
technical field [0001] The invention relates to a method for testing the reliability of the connection of a wire harness to a terminal piece. The present invention also relates to a device for testing the reliability of the connection of the wire harness to the terminal. Background technique [0002] Currently, it is often necessary to insert one end of the wire harness into a terminal (such as a plug, etc.) to realize the connection between the wire harness and the terminal. When performing this kind of termination connection, it is necessary to ensure the quality of the connection to avoid situations such as unstable connection and virtual connection. For this reason, when the wire harness is terminated and connected, the quality of the termination is traditionally judged by human experience, such as the depth and / or position of the indentation on the wire harness or the terminal fitting after the termination is completed. Experience is evaluated to determine the reliabi...
