Abstract
The embodiment of the invention discloses a circuit board with a cassette and a mobile terminal, relating to the technical field of electronics and solving the technical problems of poor reliability and short service life of the mobile terminal with a cassette. The circuit board with a cassette comprises a first circuit board, a second circuit board and a data card cassette, wherein the first circuit board is fixed with a crimp-type connector which is electrically connected with circuits thereon; a connecting structure is used for connecting the second circuit board and the first circuit board in a detachable manner, the pad on the second circuit board is in butt against with a shrapnel on the crimp-type connector to form electric connection; and the pin of the data card cassette is electrically connected with the pad on the second circuit board. The mobile terminal is composed of the circuit board with a cassette disclosed by the invention, and the first circuit board is taken as a main circuit board of the mobile terminal. The invention is applied to electric equipment such as the mobile terminal.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a circuit board provided with a card holder and a mobile terminal provided with the circuit board provided with the card holder. Background technique [0002] With the continuous development of electronic technology, mobile terminals such as mobile phones and PDAs have become the most common communication tools in people's daily life. [0003] At present, the development trend of mobile terminals is that they have more and more functions and smaller volumes. However, mobile terminals with more functions will inevitably use more electronic devices, which will inevitably lead to larger size of the mobile terminals. [0004] Taking the data card socket of a mobile phone as an example, in the existing dual-mode mobile phone, two cards need to be set, and each card is electrically connected to the circuit on the main circuit board through a data card socket. In the prior art, the...
