In fig. 1, in order to prevent friction loss, the end of the thimble 102 is set to be a smooth arc, when the thimble 102 contacts the electrical contact 202, the thimble 102 slides under pressure, so that the contact between the thimble 102 and the electrical contact 202 is poor, which causes an electrical connection failure, and finally results in that the imaging device or the read-write device cannot perform information interaction with the information holding unit 201 in the imaging box chip.
In addition, the electrical contacts arranged on the circuit board 200 are also generally small, and the ejector pin 102 on the read-write interface module is also small, so that when electrical connection is performed, high positioning accuracy is required, positioning deviation is easily caused, electrical connection failure is caused, and finally information interaction between the imaging device or the read-write equipment and the information holding unit 201 in the imaging box chip cannot be performed. Furthermore, when the process of reading information from the information holding unit 201 or writing information into the information holding unit 201 is also relatively long, the electrical contact 202 disposed on the circuit board 200 is relatively small, and the thimble 102 on the read-write interface module 100 is also relatively small, poor contact is likely to occur in the process of reading and writing information, which eventually results in that information interaction with the information holding unit 201 in the imaging box chip is not possible.
In summary, during the process of writing information into the imaging cartridge chip or reading information from the imaging cartridge chip, the information writing or reading failure is easily caused by the poor contact between the imaging cartridge chip and the reading/writing interface module of the imaging device or the reading/writing device.
