INSERTION SNAP FOR PLASTIC

by Ariel Rotman, Charle Hamisha and Uzi Cohen

  There is currently no existing part available that can be used as a combination ofan ultra sonic insert for plastic and a printed circuit board holder.

  In the development of a single board radio ter- minal unit, a requirement has arisen to place a PC board within a plastic box. This created a new part requirement.

  The part is shown in the figure and is a combi- nation of an ultra sonic threaded insert and a snap for holding the PC board. The part is made of metal

and a spring is used to hold PC boards and sub assem- blies securely, while allowing for quick removal.

  The basic principal of ultra sonic installation of threaded inserts involves high frequency vibration generating frictional heat at the metal -t-plastic interface.

  The device has the advantage of requiring fewer parts to handle during assembly and less risk ofdam- age, both ofwhich save time and money.
