Problems solved by technology

This inspection method needs to collect a large number of samples for the pull-off force test, not only the workload is heavy, but also the direct detection of the pull-off force is a destructive test, which greatly increases the testing cost

Embodiment Construction

[0040] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0042] In order to illustrate the rationality of this method, the source of variation affecting the pull-off force is firstly identified through C&E and DOE methods. For general sources of variation, through the control of suppliers, raw materials, equipment, etc., they are controlled under specified conditions, so as to eliminate the impact on pull-off force. For the main source of variation, it is necessary to conduct in-depth research through methods such as SPC and regression analysis to find the relationship between pull-off force and crimping height, and establish a mathematical model to determine the optimal crimping height.

Abstract

The invention provides a terminal pull-off force detection method. The method first aims at the specific conditions of the terminal and the wire, uses a regression analysis method to find the relationship between the terminal pull-off force and the crimping height, and then determines it according to the specific requirements of the terminal pull-off force. The value range of the crimping height, and finally through the monitoring of the crimping height of the terminal, the control of the pull-off force of the terminal is realized. The present invention determines the optimal crimping height value according to the relationship between the terminal pull-off force and the crimping height, realizes the control of the pull-off force by monitoring the terminal crimping height, and changes the detection method from destructive testing to non-destructive testing , and changed the first, middle and last piece inspection method to the first and last piece inspection method, thereby reducing the inspection frequency and inspection cost.

Description

technical field [0001] The invention relates to the technical field of wire connection, in particular to a method for detecting pull-off force of an automobile wire harness terminal. Background technique [0002] The terminal is an important part of the automobile wiring harness. It is connected between wires and wires, wires and electrical appliances, and plays the role of transmitting current and signals. The terminal and the wire are generally connected by crimping. The quality of the crimping directly affects the reliability of the connection, and the pull-off force is an important parameter to measure the quality of the crimping. At present, wire harness manufacturers generally use the first, middle and last inspection methods to monitor the terminal pull-off force. This inspection method needs to collect a large number of samples for the pull-off force test, which not only has a large workload, but also directly detects the pull-off force as a destructive test, which...
