Abstract

In order to fasten cylindrical shaped objects to other members in the miniature world of assembly we deal with- in FM Radio F'agers it usually requires multiple parts. Example: Cable Clamps require the clamp itself as well as a fastening method. You can glue, solder or screw them in place.

MINIATURE COMPRESSION ATTACHMENT METHOD

by Paul D. Giles

   In order to fasten cylindrical shaped objects to other members in the miniature world of assembly we deal with- in FM Radio F'agers it usually requires multiple parts. Example: Cable Clamps require the clamp itself as well as a fastening method. You can glue, solder or screw them in place.

An alternate method would be to use a compression clamp which takes advantage of radial clamping to its fullSSt

potential. By holding approximately 75% of the surface area using this method and combining it with a simple slot in the mating part you can eliminate using a permanent fastener (see drawing below). By changing the material thickness or the tolerance of the diameter you can achieve whatever forces are required. Using this in combination with a snapin feature makes the assembly process very fast and economical.

Applications using this method, but not limited to, include the following: Vibrator Motors, Electrical Devices or any Cylindrical object.
