Board-to-board connector assembly

A vertically extending electrical connector comprising:

• an insulative housing defining a plurality of passageways for receiving a corresponding number of cantilever contacts therein;
• two cavities formed by two sides of a center wall which extends upward from a bottom portion of the housing, wherein the center wall has a shielding end extending beyond peripheral walls of the housing;
• each of said cantilever contacts including a main body abutting against a corresponding side wall and exposed to one of said cavities, a curved distal end extending from the main body beyond the peripheral wall of the housing and engaging with the shielding end of the center wall for pre-loading before mating with a complementary connector, and a horizontally extending solder tail;
• and
• two stabilization blocks inserted into the corresponding cavities, respectively, from a bottom entry thereof, to press against the corresponding main body of each cantilever contact wherein the horizontally extending solder tail will not hinder the blocks from being inserted into the corresponding cavities.

A vertically extending electrical connector comprising:

• an insulative housing defining a plurality of passageways for receiving a corresponding number of cantilever contacts therein;
• two cavities formed by two sides of a center wall on a rear portion of the housing;
• each of said cantilever contacts including a main body abutting against the center wall and exposed to one of said cavities;
• and
• two stabilization blocks inserted into the corresponding cavities respectively from the bottom, each of said blocks pressing against the corresponding main body of each cantilever contact and having said main body sandwiched between the center wall and the block wherein each of the cantilever contacts further includes a solder tail which is formed cross the corresponding cavity by bending after the stabilization blocks have been installed.
