Pulleys are components that directly connect electrical appliances to a power source. Pulley-type power connectors offer advantages such as compact structure, quick installation and removal, and stable and reliable operation.
Material Selection
Pulleys are mostly made of high-toughness iron, nickel-plated copper, and other metal materials to ensure they do not deform during insertion and removal, and are durable.
Basic Design Steps
Taking the live/neutral plug in a common three-prong plug as an example, the design process typically includes: First, drawing a sketch of the plug's outline on a reference plane and adding dimensions; second, creating the basic shape by extruded the outline sketch, followed by fine finishing such as rounding and chamfering.
Special Functions and Structural Design
The middle plug of a three-prong plug has special electrical protection functions, and its appearance design may involve creating special curved surfaces using the "Dome" command. Some improved designs for bending resistance and breakage prevention use structures such as spiral terminals to distribute stress, prevent low-temperature breakage, and extend service life.
