Abstract

An electronic device includes a printed circuit board and a card holder. The card holder is configured to hold a function card, and the printed circuit board is provided with a groove. The card holder is disposed in the groove. A bottom surface of the groove is provided with n metal solder pads and n printed wires. The n metal solder pads are electrically connected to the n printed wires in a one-to-one correspondence. N terminals in a one-to-one correspondence to the n metal solder pads are disposed on the card holder. Each terminal is provided with a first contact and a second contact. The first contact is connected to and in contact with one of the n metal solder pads. The second contact is configured to connect to and be in contact with a metal contact of the function card placed in the card holder.
