1.1 Snap-Fit Core Assembly - GB2507495B
Key Excerpt:
"Conventionally, the insert to headerplate connection is achieved by a multi stage process. Such steps in the assembly process add time to the production cycle and often require specialist tools for example where crimping of a flange is required. Further, such connections are often prone to errors and manufacturing concessions occur"......."It is an object of this invention to provide a header plate and insert assembly which overcomes or alleviates the above problems and improves on the prior art."
