Modular electronics housing

A housing for protectively enclosing a printed circuit board, comprising:

• (a) a base (4);
• (b) a pair of parallel spaced vertical housing side walls (6, 7) extending upwardly from said base, said base and said housing side walls cooperating to define a chamber, said side walls being spaced a given distance (X1);
• (c) a vertical planar printed circuit board (LP) mounted in said chamber parallel with said housing side walls, said printed circuit board having a pair of vertical edge portions extending outwardly beyond the corresponding vertical edges of said side walls, respectively;
• and
• (d) a pair of vertical side members (14, 15), each of said side members having a generally U-shaped horizontal cross-sectional configuration including:
• (1) a transverse body portion (14a, 15a);
• and
• (2) a pair of parallel spaced leg portions (17, 18), said leg portions being spaced a distance less than said given side wall spacing distance, said leg portions cooperating with said transverse body portion to define a vertical groove;
• (e) said side members being mounted on said printed circuit board vertical edge portions with said side member extending edge portions being received in said vertical grooves, respectively, and with the side member leg portions of each of said side members extending between said housing side walls and said printed circuit board, respectively, whereby portions (21) of said housing side walls overlap said side member leg portions.
