Low-profile and robust electrical connector

An electrical connector comprising:

• a first insulator;
• a first contact supported by said first insulator and having a first contact portion;
• a second insulator faced to said first insulator in a first direction and having a side wall defining a groove which extends along said first insulator to have a first and a second part arranged in a second direction perpendicular to said first direction;
• a second contact having a second contacting portion which is placed in said second part of the groove and supported by said side wall, said second contacting portion having a flat shape and extending in a particular direction approximate to said second direction, said first contacting portion being inserted into said first part of the groove and carried toward said second part of the groove by a relative movement between said first and said second insulators in said second direction said first contacting portion having an elastic force when in said second dart of the groove, and being brought into contact with said second contacting portion with said elastic force in a third direction perpendicular to said first and said second directions,
• said first and second contacts having connecting portions exposed out of end faces of said first and second insulators in said first direction, respectively, and
• said connecting portions having depressions for receiving bumps to be connected.

• said first insulator having opposite side walls for guiding relative movement in cooperation with said second insulator, and
• said first insulator having a pair of protrusions formed on each of said opposite side walls while said second insulator has a pair of recesses formed on each of opposite end portions in said third direction to receive said protrusions.
