Abstract

A SIM card connector is provided, which is used between a SIM card and a circuit board, and comprises an insulating main body, a plurality of metal balls and a plurality of elastic assemblies. The insulating main body is arranged with a plurality of channels. The metal balls capable of rotating freely are positioned in channels of the insulating main body. In addition, the elastic assemblies are arranged in the channels of the insulating main body. One end of the elastic assembly contacts the metal ball to enable the metal part partially protruded towards the insulating main body to form a contact part contacting with the SIM card. The other end of the elastic assembly forms another contact part protruding out of the insulating main body to connect with the circuit board, thus forming a connector to reduce SIM card insertion resisting force and ensure easier and more convenient SIM card insertion.
