Abstract
A cover lid 50 for a housing 1 for electric or electromagnetic applications has parallel upper 54 and bottom 53 surfaces, these surfaces connected by a peripheral lateral surface that has a bevelled edge 58, preferably adjacent the bottom surface. The lid 50 is preferably press-fit into a reception space (20) of housing (10) (see fig 4) that contains a PCB (24) where the housing may also have an further external lid that encloses the cover lid. The lid may have peripheral recesses that provide for some resilience when the lid is press-fitted, as the lid is made slightly bigger than the reception space. A method of assembly of the housing with a cover lid is disclosed, where the position of a press fitted lid is monitored by detecting the effect on the enclosed electronics. The position of the lid may alter the impedance of transmission lines inside the housing. The position may thus be optimised for a preferred impedance.
