Push-fit shield
First Claim
1. An EMI/RFI shield assembly for shielding components affixed on a printed circuit board, comprising:
- a frame affixed to the printed circuit board;
a lid operatively connected to said frame;
said frame including sidewalls each having a top portion and a bottom portion;
said bottom portion of each sidewall including a preselected series of crenels and merlons formed therein;
said crenels having an upper terminating edge disposed at a predetermined distance from said merlons;
said lid including a cover wall portion and a plurality of engagement elements extending from said cover wall portion such that at least one of said engagement elements is operatively associated with each said sidewall;
each said engagement element including a surface for operative connection with said frame such that said at least one of said engagement elements engages said upper terminating edge of one of said crenels, whereby said lid is biased toward said frame and compensating for tolerance stack-up.

Abstract
An EMI/RFI shield assembly for shielding printed circuit board components, including a frame affixed to the PCB, and a lid connected to the frame. The frame sidewalls each have top and bottom portions. Each bottom portion includes formed series of crenels and merlons. The crenels have a termination edge disposed a predetermined distance from the merlons. The lid includes a cover wall portion and engagement elements extending therefrom such that at least one of the engagement elements is associated with each sidewall. Each engagement element includes a surface for connection with the frame at the upper terminating edge of one of the crenels, whereby said lid is biased toward the frame compensating for tolerance stack-up.
