ABSTRACT:
A segmented housing for electrical instrumentation particularly panel mounted meters of the electro-optical readout variety. The housing is formed in first and second halves separating the housing into substantially similar upper and lower portions which are secured together and to a panel mounting bracket by recessed bolts on opposite sides. The brackets are located in side channels extending a substantial portion of the housing side length to provide a highly rigid and secure attachment. The housing halves are apertured in the rear to permit electrical connection through lugs to a circuit board within. The front halves are apertured and beveled for panel mounting with a molding surrounding the aperture through which an indicator scale is visible. One or more lens elements provides scale indication and/or scale magnification. The housing resulting from the securing of the two halves together forms a trim, flat package such that a plurality of the units may be closely stacked for high density display applications. The entire housing structure aside from the brackets is preferably injection molded of plastic.
