A stackable connector interface with magnetic retention for electronic devices and accessories can allow power and data to be transferred between one or more stacked connectors. Each interconnected stackable connector includes one or more magnetic elements, which magnetic elements have poles arranged to facilitate mating with other stackable connectors. The magnetic elements provide a magnetic retention force that holds mated connectors in contact with each other. In some embodiments, the connectors include connection detection circuitry for determining whether the connectors are mated with other connectors, thereby allowing the connectors to prevent live contacts from being exposed at an unmated surface of the connectors. In some embodiments, routing circuitry is included to determine how signals should be transferred between the interconnected stackable connectors and/or corresponding devices.

A SIM card connector includes an insulating body, a plurality of first terminals and a plurality of second terminals. The insulating body has a plurality of first slots and a plurality of second slots. Each side wall of each first slot has a limiting slot. The plurality of the first terminals are inserted into the plurality of the first slots. Each first terminal has a first base portion, a first soldering portion connected with a lower end of the first base portion, and a first contacting portion connected with an upper end of the first base portion. The plurality of the second terminals are inserted into the plurality of the second slots. Each second terminal has a second contacting portion slantwise extended towards a rear end of the insulating body and exposed beyond a top surface of the insulating body.

An electronic device includes an analog connector and a digital connector. The analog connector has one or more analog signal contacts and at least one other contact. A signal detector detects signals at the other contact. A switch is coupled to the other contact to, where analog signals are at the other contact, to cause the switch to transition a connection to other contact from a common node of the device to a signal node of the device, thereby allowing a user to use either a four-wire accessory device or five-wire accessory device with a four-wire analog connector.

The card connector includes a card connector base and a limiting structure. The card connector base includes a first area and a second area, the limiting structure includes a first limiting part and a second limiting part; the first limiting part is used to limit a first data card in the first area, and the second limiting part is used to limit a second data card or a third data card in the second area; a first spring plate group is disposed in the first area and is configured to electrically connect to edge connectors of the first data card; a second spring plate group and a third spring plate group are disposed in different positions of the second area; the second spring plate group is configured to electrically connect to edge connectors of the second data card; the third spring plate group is configured to electrically connect to edge connectors of the third data card.
