Snap fit的意思

"Snap fit" is a term used in engineering and manufacturing, particularly in the context of plastic or rubber parts, to describe a type of fastening where two pieces fit together tightly due to a series of protrusions or "fingers" on one part that snap into holes or notches on the other part. This creates a secure connection that does not require any additional fasteners such as screws, bolts, or glue.

The snap fit mechanism is designed to be easy to assemble by hand, with a tactile and audible "snap" sound indicating that the parts are properly connected. This type of connection is commonly used in consumer products, toys, electronic enclosures, automotive components, and medical devices, among others.

Snap fits can be uni-directional (where the parts can only be snapped together in one orientation) or bi-directional (where the parts can be snapped together in either orientation). They can also be designed to be removable or permanent, depending on the application.

Snap fits are advantageous because they simplify the assembly process, reduce the need for tools, and can provide a strong and reliable connection. However, they may not be suitable for applications that require frequent disassembly or where high vibration or stress may cause the connection to fail.
