In SJ / t1166 general specification for IC card socket, IC card for socket must conform to the definition of GB / t16649 IC card socket identification carrier contactor (ISO7816). This kind of card is SIM card, so SJ / t11166 is the general specification of SIM card.

Although SD card socket can not be used as identification card socket, its structure and function are similar to SIM card socket, but the interface size and technical requirements are different. SJ / t11166 can be used as the applicable general specification.

Its structure size includes interface size and shape size, any socket must be standardized. The contact position and identification card size meet the requirements of GB / t16649.2. The corresponding position and contact direction of socket and contact point are specified in t11166. According to the actual size of the SIM card, the contact point position and contact surface range are specified.

Finally, according to the needs of users and the characteristics of SIM and SD card holders, SJ / t11166 is selected as the overall specification, and the structural dimensions, overall dimensions, performance requirements and test methods are strictly specified. The push-pull SIM card connector refers to the standard version and calibration standard corresponding to the track standard, and the SIM card is compiled according to the standard. The detailed specifications of SD and SD socket have been put into production. The standardization of SIM socket and SD socket is realized. Environmental requirements are not specified in the detailed specifications, but it has become a consensus that all materials used in products must meet the environmental requirements.

SIM card holder and SD card holder are widely used to meet the needs of connection and information exchange between SIM card and SD card. This standard takes SJ / t11166 as the general specification, and specifies the structure, size, performance and test tightness. This version of the standard is used to develop and implement detailed standards to meet the standardization requirements of SIM card and SD card.
