Coupling mechanism for an electrical fitting including energy absorbing self-returning snaps

A raceway fitting, comprising:

• a first housing portion adapted to couple to a first mounting surface and having a bottom surface and at least one wall extending from said bottom surface, said at least one wall having a portion with a first surface having a first edge and a second surface having a second edge and an end surface proximal to said bottom surface, said first edge being located farther from said bottom surface than said second edge, and said end surface extending from said first edge to said second edge;
• and
• a second housing portion adapted to couple to said first housing portion and having a top portion and at least one side portion extending from said top portion, said side portion having a protrusion extending therefrom;
• whereby when coupling said second housing to said first housing, said protrusion is engages said end surface adjacent said first surface and traverses said end surface in the direction of said second surface, and said protrusion is urged along said end surface in the direction of said second surface by said at least one side portion.

A raceway fitting, comprising:

• a first portion having a first wall with a recess therein, said recess having a first edge and a second edge;
• and
• a second portion having a second wall with a protrusion thereon, said protrusion having a first tapered surface with first and second ends, said tapered surface extending from said second wall at said second end at an oblique angle;
• whereby when said second portion is being coupled to said first portion, said first edge of said recess traverses said tapered surface from said first end to said second end, so that said second end is adjacent said first edge, to facilitate the coupling of said first and second portions.

A raceway fitting, comprising:

• a first housing member having a bottom surface and at least one side wall extending from said bottom surface, said at least one side wall having a recess with a first wall and a second wall;
• a second housing member adapted to couple to said first housing member and having a top portion and at least one side portion extending therefrom;
• and
• a latching member extending from said side portion, said latching member having a tapered portion with a first end and a second end that engages a portion of said first wall of said recess when coupling said second housing to said first housing, said tapered portion being biased against said first wall by said at least one side portion, thereby urging a portion of said tapered portion to traverse said portion of said first wall from about said second end to about said first end and facilitate the coupling of said first and second housing members.
