Low coupling force connector assembly

A low coupling force connector assembly comprising:

• a first connector having a housing with a plurality of sub connectors fixed therein;
• a plurality of second connectors, each having an upper and lower bosses projecting thereon, corresponding to said sub connectors;
• and
• a first and second sliders, each having a pair of opposed slider plates with one or more pairs of opposed cam grooves formed thereon, said cam grooves guiding therealong said bosses of a respective one or ones of said second connectors to fit said second connectors to said sub connectors, said pairs of opposed slider plates of said first and second sliders, the latter inside the former, being longitudinally slidable relative to each other between a telescopically-expanded position and a telescopically-contracted position,
• wherein said pairs of opposed slider plates of said first and second sliders, in said telescopically-expanded position, are inserted into said housing of said first connector from a direction traverse to a fitting direction of said first and second connectors, and said pair of opposed slider plates of said first slider, with said cam grooves of said first and second sliders engaged with said bosses of said second connectors, is pushed and moved to said telescopically-contracted position so as to make said pair of opposed slider plates of said second slider follow said pair of opposed slider plates of said first slider into said housing, whereby to fit said second connectors to said sub connectors of said first connector at staggered times.
