Electrical connector having contact retained therein

An electrical connector comprising:

• an insulating housing comprising a top and bottom surfaces opposite to each other in an up-to-down direction and a plurality of receiving holes running through the top and bottom surfaces, the dimension from the top surface to the bottom surface in the up-to-down direction defined as the height of the insulating housing, a plane on half the height of the insulating housing defined as the centre plane of the insulating housing;
• and
• a plurality of contacts received in the receiving holes, the contact comprising a plate like base portion defining two sides opposite to each other in a horizontal direction perpendicular to the up-to-down direction, wherein;
• the contact engages the insulating housing and defines a top engaging point and a lowest engaging point, the area between the top engaging point and the lowest engaging point is defined as an engaging area, a centre line of the engaging area is parallel to the centre plane of the insulating housing, and the distance between the centre line of the engaging area and the centre plane of the insulating housing is not more than 1/10 the height of the insulating housing.
