Electrical terminal and electrical connector in vertical compression contact with chip module

An electrical connector, configured to be electrically connected to a chip module, the electrical connector comprising:

• a body, having a plurality of accommodating holes running vertically;
• and
• a plurality of electrical terminals, respectively accommodated in the accommodating holes correspondingly, wherein each of the electrical terminals has:
• a base, being flat plate shaped;
• a strip connecting portion, formed by extending upwardly from an upper end of the base, and configured to be connected to a strip;
• a first elastic arm formed by extending upwardly from the an upper end of the base, wherein a top portion of the first elastic arm has a mating portion configured to upwardly abut the chip module, a through groove runs through the first elastic arm along a thickness direction of the first elastic arm, one of an upper end and a lower end of the through groove is defined as a first end, and the other of the upper end and the lower end of the through groove is defined as a second end;
• and
• a second elastic arm, wherein one of an upper end and a lower end of the second elastic arm is defined as a third end, the other of the upper end and the lower end of the second elastic arm is defined as a fourth end, the third end is integrally connected to the first end, the fourth end is integrally connected to the second end prior to being formed and is broken from the second end after being formed, the second elastic arm has a contact portion, and when the chip module is pressed downwardly on the mating portion to a final position, the contact portion is in contact with the base or the first elastic arm;
• wherein when the first end is the upper end of the through groove and the second end is the lower end of the through groove, the third end is the upper end of the second elastic arm and the fourth end is the lower end of the second elastic arm;
• and when the first end is the lower end of the through groove and the second end is the upper end of the through groove, the third end is the lower end of the second elastic arm and the fourth end is the upper end of the second elastic arm.
