Error prevention of connectors in automotive wiring harness design

First, the value of error-proof connector application in automotive wire harness design

In the process of automotive product design and manufacturing, it is necessary to analyze the relevant situation from a diversified perspective, especially the error-proof function design process, and the series connector error-proof design carried out by designers should start from the design source, actively integrate and solve the efficiency while ensuring the effectiveness of error-proof location management. In addition, technicians should optimize the error prevention efficiency of instrument switchgear, deep and shallow clutch, and the butt effect under the A-pillar in the automotive wiring harness design. In other words, only the connector in the automotive wiring harness design is error-proof, in order to avoid the transmission of defects to the customer, but also to reduce the productivity of waste products, so as to effectively improve the basic quality of the product, and to a certain extent optimize the application effect of the automotive wiring harness design, maintain the stability and safety of the vehicle operation, and promote the overall progress of the automotive industry.

Second, the fault prevention method of the connector in the design of the automobile wire harness

In the process of establishing the error prevention system, it is mainly divided into structural error prevention, component error prevention, color error prevention and size error prevention, etc., which can establish a targeted error prevention control system according to different requirements. At present, the instrument switch group commonly used structure error prevention, component error prevention, color error prevention; The driver/passenger seat uses the structure to prevent errors; Deep clutch and shallow clutch use size and color error prevention; Rear seat belt switch using size error prevention, etc.

(1) Structural error prevention of connectors in automotive wiring harness design

In the process of automotive wiring harness design, in order to effectively conduct comprehensive treatment of connectors near the position, it is necessary to improve the treatment effect of the same type and different structure connectors combined with the electrical end, to ensure that the error prevention effect can be fundamentally improved, on the basis of improving the design effect, it is necessary to control and manage the electrical end of different structures, and try to improve the same type of connection processing. Reduce the number of intermediate terminals that occur during harness production.

For example, in the design process of the co-pilot gravity sensor of a certain model, the design component of MG610392 model selected in the early stage, however, the problem of misinsertion often occurs during the test run. In order to effectively improve the error prevention effect, the technical department needs to upgrade and improve the co-pilot gravity sensor model, and optimize the electrical side synchronously. Thus, the application effect of the structure can be improved and the error prevention control effect can be realized.

(2) The components of the connector in the design of the automotive wiring harness are error-proof

In order to fundamentally ensure the application effect of the connector, it is necessary to analyze and actually determine the design selection work, and fundamentally improve the basic level of the error-proof effect in the design effect.

First, in the process of connector design and selection, it is necessary to combine the application requirements of the electrical end to ensure that the connector with a certain difference in shape is selected, and a high matching mechanism is established to ensure the effectiveness of the plug-in control work. In addition, the tail shape should be effectively improved to enhance the practical application value of the overall shape and improve the error prevention effect.

Second, it is necessary to process and analyze the self-locking or back cover of the connector, effectively integrate the connector body project, select different back cover or self-locking system, to process the self-locking size parameters, exit direction parameters and guidance slots, and use color error prevention to improve the overall error prevention effect.

(3) Color error prevention of connectors in automotive wiring harness design

After the actual automotive wiring harness design work is carried out, the technical department should conduct overall analysis and judgment according to the actual requirements, effectively integrate the color system, rationally improve the intuitive processing mechanism, and hang the color error prevention. That is to say, designers should supervise and manage the limitations of the design process of parts and connectors, improve the effectiveness of error prevention work, and conduct a comprehensive analysis of color error prevention. Only by ensuring that the color design and marking work meet the requirements of error prevention can the effectiveness of error prevention be improved.

(4) The size of the connector in the design of the automobile wire harness is error-proof

The so-called dimensional error prevention is to comprehensively deal with the possible error prevention parts, the relevant designers should determine the differentiated function connector branches, guide the fixed parts with the direction of the wire or the buckle, and reasonably improve the comprehensive effect of the error prevention effect. The most important thing is that in the ideal size system, the connector and the electrical end plug should be restricted and managed to ensure that the connector can meet the requirements on the basis of consistency, and the overall plug effect can also meet the size error prevention goal. For example, in the design work of the deep clutch and shallow clutch harness of a certain model, the design department chooses the same style plug-in, which needs to rationally optimize the size error prevention effect on the basis of quality management, combined with the verification mechanism to maintain the equipment matching requirements, and improve the effectiveness of the operation.

(5) Alignment and error prevention of connectors in automotive wiring harness design

In order to achieve the goal of automobile wiring harness design effectively, the design process should also supervise and control the specific work flow. In particular, some design work that cannot practice shape error prevention, color error prevention and size error prevention should be integrated with specific connector design work to improve the comprehensive level of error prevention function, and also lay the foundation for the comprehensive optimization of subsequent processing effects. In addition, it is necessary to conduct an overall analysis of the connector according to the basic requirements of the design principle and layout space, improve the operation effect of the exchange position, and improve the effect of the connection and error prevention.

In addition, in the process of designing the wiring harness, the design department should also centrally manage the dressing and error prevention, the direction of the wire and the fixed type, effectively improve the fixed effect, ensure the optimization of application efficiency, and maintain the wiring harness design connector processing effect.

Third. Conclusion

All in all, the connector in the automotive wiring harness design should integrate the error-proof method, improve the overall quality of the product on the basis of reducing the operation and production costs of the automotive project, but also to reduce the defect problem to provide a guarantee, to a certain extent, improve the market competitiveness of enterprise products, to achieve a comprehensive upgrade of management work, It also lays the foundation for the accurate and effective matching of the corresponding components and promotes the overall progress of the automotive industry.
