Latch mechanism for a housing

A housing comprising:

• a chassis having at least a locking hole;
• a front panel having at least a match opening, a pair of parallel planar boards formed in the match opening, each of the planar boards forming a notch;
• a cover connected together with the front panel to be latched and released with and from the chassis;
• a latch member comprising a base mounted in the match opening of the front panel and an arm integrally extending toward the chassis from the base to enter the locking hole, a top and a bottom of the base respectively forming a protrusion, the notches of the planar boards respectively receiving the protrusions, wherein the width of each notch is adequate to provide the protrusion moving therein, the outer end of the arm provided with a hooked portion to engage the side edge of the locking hole, the latch member being movable between a locked position where the arm is locked in the locking hole and a position where the arm disengages the locking hole;
• and
• a spring urging against the base to retain the latch member in the locked position.

A housing comprising:

• a chassis defining at least a locking hole;
• a front panel and a cover assembled to said chassis in a front-to-back direction;
• a latch member retainably positioned between said front panel and said cover, and also being moveable in a lateral direction perpendicular to said front-to-back direction, said latch member including a base exposed to and accessible from an exterior in said lateral direction, and
• a hook portion releasably engaged with the locking hole to prevent the front panel and the cover from forward moving.
