Abstract

The utility model provides a chip contact mechanism, which comprises a circuit board and a plurality of contact pins, wherein the circuit board is arranged on a printer; and the contact pins are used for contacting contacts on a chip. The contact pins are columnar contact pins which are arranged on the circuit board and electrically connected with the circuit board, and can be elastic contact pins which can be retracted in the axial line direction of the pins so as to bring convenience to the mounting of an ink box and prevent the contact pins from being broken or deformed. The elastic contact pins comprise base bodies and contact heads, wherein the base bodies are fixedly connected to the circuit board; the contact heads can retract and move relative to the base bodies; and an elastic part is arranged between the contact heads and the base bodies. A contact pin bracket with a complex structure is not required to be arranged in the chip contact mechanism, so the structure is simplified; the manufacturing cost is reduced; and the working stability and reliability of the printer are improved at the same time.
