Various types of connectors are used in home appliances and air-conditioning systems to create reliable contacts between different parts of electric circuits. In recent years, the number and types of connectors have multiplied as advanced sensors, controls, and communication/networking capabilities are incorporated into more intelligent appliances. Each connector must be properly assembled to minimize signal distortion or power loss, but also to meet the required pressure resistance and mean-time-between failure (MTBF) of connect/disconnect operations over the product’s lifetime.
Although robots and automation are used for some connector-assembly tasks, many connectors are still assembled by hand. To minimize human error, manufacturing engineers are proactively identifying ergonomic issues that affect worker and connector performance. Applying the insights of ergonomics—the science for optimizing the design and arrangement of the work environment—can improve workplace efficiency and safety. By understanding common trouble spots and implementing best practices, an appliance manufacturer can ease the human strain of assembly, reduce worker turnover, and prevent errors to minimize in-warranty service calls and repairs of products in the field.
