Description

TECHNICAL FIELD

[0001] The utility model relates to communication equipment, in particular to a kind of soft contact SIM card connecting device and communication terminal. BACKGROUND

[0002] In the modern communication technology field, the reliability and stability of communication terminal are crucial. With the wide application of mobile devices in various environments, such as vehicle-mounted systems, industrial control devices, medical monitoring devices, etc., these devices will inevitably be subjected to mechanical vibration during operation. Especially in the environment of vehicle-mounted and rail transportation, due to the bumping and shaking during vehicle driving, higher requirements are put forward for the stability of internal communication components.

[0003] The existing communication terminal technology mainly has the following technical characteristics and problems:

[0004] Directly welded SIM card seat: In many existing communication terminal designs, the SIM card seat is directly welded on the mainboard. This hard connection method makes any frequent mechanical vibration directly transmitted to the SIM card seat, causing the connection between the SIM card and the SIM card seat to occasionally break, thereby causing communication interruption.

[0005] Hard contact problem: In some designs, the contact between the SIM card seat and the SIM card is hard against hard, i.e. both are hard materials. Under the influence of frequent mechanical vibration, this hard contact will cause the SIM card and the SIM card seat to disconnect, which will also cause communication interruption.

[0006] Lack of shock absorption measures: The existing SIM card seat is directly connected with the shell without effective shock absorption measures. Under the influence of frequent mechanical vibration, this design will cause the SIM card and the SIM card seat to be unstable, increasing the risk of communication interruption.
