However, it does not take into account that the temperature in the accelerated test is different from that in the actual work
The above-mentioned patents have focused on a certain aspect of research, but the working environment of the robot connector is complex, and various factors affect each other. The reliability of the robot connector and the test of the working life also need to reproduce the working environment as much as possible. Under the condition
At the same time, there are also relevant literatures that show that under different plugging temperatures and speeds, the number of plugging and unplugging has a great influence on the reliability of electrical connectors.

The invention discloses a robot connector reliability acceleration test method and device. Under different plugging temperatures and speeds, the plugging times have great influence on the reliabilityof the electrical connector. The robot connector reliability acceleration test method comprises the following steps: 1, establishing a test parameter set; and 2, carrying out a model establishment test; 3, establishing a derivation model of the contact resistance, the signal fidelity ratio, the average width of the grinding marks and the average depth of the grinding marks; 4, calculating characteristic parameters; 5, establishing a derivation function of the tested connector under each acceleration condition; 6, selecting a finally used acceleration condition and derivation function through afuzzy decision. According to the robot connector reliability test method, the derivation model is established by taking the temperature, the plugging force and the plugging speed as acceleration conditions, the optimal derivation model is selected in a fuzzy decision mode, the derivation model fully considers the functions of the connector assembly in data transmission and energy transmission, and the defects of an existing robot connector reliability test method are overcome.
Description
technical field [0001] The invention belongs to the technical field of accelerated testing of reliability of connectors, and in particular relates to a method and device for accelerated testing of reliability of robot connectors. Background technique [0002] As a basic electrical component, electrical connectors are used to realize the transmission and control of electrical signals and the electrical connection between electronic and electrical equipment. In industrial manufacturing, connectors make complex and huge system structures modular and play various roles. an important role. Due to the influence of machine operation and working conditions, the loss and failure of connectors often cause great damage to the working machinery. The reliability and life of the connectors even determine the stability of the product's control system, communication system, data transmission, and working voltage. Therefore, through certain technical means to measure the reliability and wo...
