• a slider (30, 31) positioned adjacent each side wall, each slider having a first open-sided channel (74) having a closed end (76), a second open-sided channel (80) having side edges (82, 83), an upper edge (55), a lower edge (50), a pair of inclined cam surfaces (46) having openings (48), and a resilient tab (52), the upper and lower edge (55, 50) making a sliding engagement with the slide surfaces of the upper wall and the lower wall, respectively, of the side walls, the openings (48) located in the lower edge (50) alignable with the apertures (38) in the lower wall of the side walls, the resilient tab (52) aligned to make a snap fit in the first aperture (34) or the second aperture (36) in the side wall, the first channel extending arcuately from the upper edge (55) of the slider, the second channel extending parallel with the mating axis from the upper edge;
• a U-shaped lever (58) having a pair of arms (60), each arm having a first pin (66) and a second pin (68), the first pin engaged slideably up to the closed end (76) of the first open sided channel (74) in each slider (30, 31), the second pin engaged slideably between the side edges (82, 83) of the second open-sided channel, the first and second pins (66, 68) for sliding each slider upon pivoting of the lever relative to the first part housing, the slider moving relative to the adjacent side wall, the sliding direction being perpendicular to the mating axis;
• a pivot means (62, 72) on each arm (60) and each upward extension (70) of each side wall to allow the lever to pivot relative to the first part housing, the first and second pins radially spaced equally from the pivot means (62) on each arm;
• and
• a second part housing (106) mateable with the first part housing (16) along the mating axis, the second part housing (106) having side walls (108) and end walls (110) disposed inside the side walls (18, 20) and end walls (22) of the first part housing (16), each side wall (108) of the second part housing (106) having a pair of spaced cam followers (112) positioned to pass through the apertures (38) in the lower walls (26) and the openings in the inclined cam surfaces for sliding movement along the cam surfaces, pivoting movement of the lever moves the second part housing relative to the first part housing along the mating axis between a fully unmated position in which the resilient tabs (52) on each slider make a snap fit in the first aperture (34) in the side walls (18, 20), and a fully mated position in which the tabs on each slider make a snap fit in the second aperture (36) in the side walls (18, 20), wherein a first and second pins (66, 68) are on an arc-shaped portion (64) at the free end of each arm (60) of the lever (58).

An electrical connector comprising:

• a first part housing (16) having opposed side walls (18, 20), opposed end walls (22), and a mating axis, each side wall having an upper wall (24), a lower wall (26), a first spaced aperture (34), a second spaced aperture (36), a pair of spaced apertures (38), an upward extension (70) and a tab (92), the upper and lower wall (24, 26) defining the opposed slide surfaces (28), the slide surfaces (28) perpendicular to the mating axis, the first and second spaced apertures (34, 36) positioned through each side wall, the pair of spaced apertures (38) positioned through the lower wall of each side wall, the upward extension (70) extending upward from the upper wall of each side wall, the tabs (92) positioned rigidly in opposition between the upper and lower wall (24, 26);
• a slider (30, 31) positioned adjacent each side wall, each slider having a surface (54) facing the side wall (18, 20), an upper edge (55), a lower edge (50), a pair of inclined cam surfaces (46) having openings (48) in the lower edge, a resilient tab (52), and a slot (86) having an end (90) and a shoulder (88), the upper and lower edge (55, 50) engaged slideably with the upper and lower walls, respectively, of the side walls, the openings (48) alignable with the apertures (38) in the lower wall of the side walls, the resilient tab (52) aligned to make a snap fit in the first aperture (34) or the second aperture (36) in the side wall, the slot (86) formed in the surface (54) and perpendicular to the mating axis, the slot open at end (90) for receiving the tab (92);
• a U-shaped lever (58) having a pair of arms (60);
• a pivot means (62, 72) on each arm (60) and each upward extension (70) of each side wall to allow the lever to pivot relative to the first part housing;
• a drive means (66, 74;
• 68, 80) on each arm and each slider to slide each slider relative to the adjacent side wall on pivoting of the lever relative to the first part housing;
• a second part housing (106) mateable with the first part housing (16) along the mating axis, the second part housing (106) having side walls (108) and end walls (110) disposed inside the side walls (18, 20) and end walls (22) of the first part housing (16), each side wall (108) of the second part housing (106) having a pair of spaced cam followers (112), positioned to pass through the apertures (38) in the lower walls (26) and the openings in the inclined cam surfaces for sliding movement along the cam surfaces, pivoting movement of the lever moves the second part housing relative to the first part housing along the mating axis between a fully unmated position in which the resilient tabs (52) on each slider make a snap fit in the first aperture (34) in the side walls (18, 20), and a fully mated position in which the resilient tabs on each slider make a snap fit in the second aperture (36) in the side walls (18,20), and wherein the pivot means comprises a pivot aperture (72) in the upward extension (70) of each wall (18, 20) of the housing (16) of the first part (12) which makes a snip fit with a pivot pin (62) on each arm (60) of the lever (58).
