Snap connection
Snap connections are functional elements for releasable and non-releasable, simple, form-fitting joining of components. In the process, a component to be joined is elastically deformed and then hooks in a detachable or non-detachable manner. So there is a form fit . There are different versions:
- Snap hook
- Ball joint connection ("snap ball")
- Ring snap connections ("snap cylinder")
With snap connections, the elasticity of the materials, usually plastics or spring steel , is used to connect two components.
They are used to a large extent in industrial mass production in the automotive sector and in the consumer goods industry, where the integration of functions enables significant savings in assembly processes.
Examples
- Jack plug and socket
- Cable ties - snapping in repeatedly
- Permalok - connection for thick-walled steel pipe with several turned snap edges
- Snap fastener on textiles
- Press studs on boat tarpaulins with releasable locking
- Cable ducts made of PVC in brackets mounted on the wall and ceiling
- Plastic housing of electrical appliances
- Surprise egg
- Chest lid and box door can be kept closed with mounted catches or magnets - each in two parts
- Plastic dustpan and hand brush often snap into one another at the handles
- Car glove box, doors and some windows snap shut, fall into the lock when a latch is pushed into the lock through an edge (of the strike plate on a door frame) and then pops out again. This snap action has a locking effect. Only the actuation of the rotary knob, pushbutton or door handle (commonly known as "door handle") opens the lock again.
- Plastic cap on tin can with beaded rim or bottle mouth with groove
