Abstract: An electrical connection system includes an electrical connector electrically connected to a chip module, and an adapter disposed on one side of the electrical connector. The chip module laterally extends to form a conducting portion. Two rows of terminals are disposed in the adapter, and form a slot therebetween for the conducting portion to be inserted therein. When the conducting portion is not inserted in the slot, the width of the slot is greater than the thickness of the conducting portion, so that a zero insertion force is required for insertion of the chip module. After the chip module is inserted in the slot, under the effect of an external force, the width of the slot is reduced to an extent that the terminals urge against the conducting portion, which ensures close electrical connection between the terminals and the chip module.
