Abstract

The terminal portions 222a, 222b of the contacts having the contact portions 221a, 221b belonging to (2n/2)-th contact portion tier 2-21 are arranged so as to be alternately allocated to the first terminal portion tier 1-22 and the second terminal portion tier 2-22.

Claims

1. An electrical connector comprising an insulator and a plurality of contacts arranged in line in a width direction of said insulator;

wherein said contacts have a contact portion adapted to be detachably connected to a first connection object and a terminal portion adapted to be fixedly connected to a second connection object, respectively;

said contact portions of said contacts are arranged in first to (2n−

1)-th contact portion tiers superposed in a vertical direction perpendicular to the width direction of said insulator, the variable n being an integer no less than 2;

said terminal portions of the contacts having the contact portions belonging to the first to ((2n/2)−

1)-th contact portion tiers are arranged in a first terminal portion tier of the first and second terminal portion tiers superposed in the vertical direction of said insulator;

said terminal portions of the contacts having the contact portions belonging to ((2n/2)+1)-th to the (2n−

1)-th contact portion tiers are arranged in said second terminal portion tier; and

said terminal portions of the contacts having the contact portions belonging to (2n/2)-th contact portion tier are arranged so as to be alternately allocated to said first terminal portion tier and said second terminal portion tier.

2. The electrical connector according to claim 1, wherein said contacts having the contact portions belonging to (n−

m)-th contact portion tier and said contacts having the contact portions belonging to (n+m)-th contact portion tier are same in shape, the variable m being an integer no less than 1 and less than n; and

said contacts having the contact portions belonging to the (2n/2)-th contact portion tier are same in shape.

3. The electrical connector according to claim 1, wherein said second connection object has a plate-like shape, and

said first and said second terminal portion tiers are fixedly connected to first and second plate surfaces of said second connection object, respectively.

4. The electrical connector according to claim 3, wherein said contacts have elasticity, and

said first and second terminal portion tiers press against said first and said second plate surfaces of said second connection object, respectively, so as to hold therebetween said second connection object in said vertical direction.
