Chip connector with improved terminals

A chip connector comprising:

• an insulating housing defining an upper face, a lower face, and a plurality of terminal grooves going through the upper face and the lower face;
• and
• a plurality of conductive terminals received in the terminal grooves respectively, each of the terminals comprising a fixing portion and an elastic arm extending slantwise and upwards from the fixing portion, the elastic arm having a contacting portion located above the upper face of the insulating housing;
• wherein the terminal is integrally stamped from a metal sheet and the terminal further comprises an attachment portion located below the elastic arm, the attachment portion faces and is parallel to the main portion with a certain distance, and a height of the attachment portion is more than one third of a height of the main portion and the certain distance between the main portion and the attachment portion is 4 to 5 times of the thickness of the metal sheet.
