PURPOSE: To provide a structure having low inserting force, strong electric contacting force, and moreover no movable part in respective housings, by making plate spring contact beams, cantileveredly supported respectively, have a reversely curved shape with each other so as to have female-male structure. CONSTITUTION: A beam 16 has a first bent part 20, adjoining a base 12 to separate from the center plane P; and a second bent part 22, adjoining the part 20 and being in a reverse direction. A third bent part 24 is made to cross the center surface P to direct the beam 16 rearward, and demarcates a rear contact surface 26 between the parts 22 and 24. A rear cam surface 30, crossing the center plane P from the curve part 24 to extend to a fourth bent part 28, is demarcated, and a fifth curve part 34 is provided to form a front contact surface 36. A second cantilever type contact beam 18 is curved in a reverse direction, and the beams 16 and 18 are made nearly symmetrical to the center surface P. This makes inserting force low, electric contacting force strong, and moreover the movable parts of respective housings unnecessary. |
