Abstract

Most highly environmental resistant panels or lenses (clear panels) require product disassembly in order to access what is underneath the panel. Conversely, most panels that are easily removable do not provide a high degree of environmental resistance. In many applications there are needs for panels that provide both high environmental protection and easy accessibility (l/O ports, labels that may require changes, battery doors, encoding/decoding switches, etc.).

REMOVABLE HIGHLY ENVIRONMENTAL RESISTANT LENS OR PANEL ASSEMBLY

by Robert D. Lloyd

   Most highly environmental resistant panels or lenses (clear panels) require product disassembly in order to access what is underneath the panel. Conversely, most panels that are easily removable do not provide a high degree of environmental resistance. In many applications there are needs for panels that provide both high environmental protection and easy accessibility (l/O ports, labels that may require changes, battery doors, encoding/decoding switches, etc.).

A method of achieving both requirements as follows. The panel may be a flat sheet (1) or have stepped
(2) or beveled (3) side edges (optional at seated edge (4)) that slide into grooves of the housing. The groove overhang (5) stops short at the insertion end (6) so that the bottom wide step or bottom wide bevel dimension
(7) of the recess feature can run clear to the top of the opening and allow the insertion or extraction of the panel. The distance (8) at which this overhang stops is calculated so that when the free-end of the panel (9) clears the top edge of the insertion end of the housing recess that the force created on the panel, by the overhang bending it, causes it to snap into position. Extraction of the panel is made by placing a tool (10) into the small hole (11) in the panel and bending the free end of it up to clear the top edge of the recess to allow it...
