Embodiment 1

[0052] Such as figure 1 , figure 2 and image 3 As shown, the circuit board provided with the card holder provided by the embodiment of the present invention includes a first circuit board 1, a second circuit board 2 and a data card holder 3, wherein:

[0053] The first circuit board 1 is fixed with a crimping connector 4 electrically connected to the circuit on the first circuit board 1;

[0054] The second circuit board 2 is detachably connected to the first circuit board 1 through the connection structure 57, and the second circuit board 2 is as Figure 5 pad 20 shown with a crimp connector 4 as Figure 4 The shown elastic pieces 40 abut against each other to form an electrical connection;

[0055] Data card holder 3 such as Figure 6 The shown pins 30 are electrically connected to the pads 20 on the second circuit board 2 .

[0056] Since the main circuit board in the mobile terminal of the present invention, namely the first circuit board 1, is fixedly provided wit...

Embodiment 2

[0067] Such as Figure 11 , Figure 12 and Figure 13 As shown, this embodiment is basically the same as Embodiment 1, and the difference is that in this embodiment, the connection structure 57 also includes a bracket 9 located between the first circuit board 1 and the second circuit board 2, wherein:

[0068] The bracket 9 includes an edge portion 90 provided with at least one through hole 93, a recessed platform portion 91 concaved toward the direction approaching the first circuit board 1, and a notch 92 provided on the bottom surface of the concave platform portion 91;

[0069] The pad 20 on the second circuit board 2 passes through the notch 92 and the crimp connector 4 such as Figure 14 The shown elastic pieces 40 abut against each other to form an electrical connection;

[0070] The through holes 93 are opposite to the mounting holes 6 and the screw holes 5 respectively, and the screws 7 fix the second circuit board 2 on the first circuit board 1 through the mountin...

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 handheld computers have become the most common communication tools in people's daily life. [0003] At present, the development trend of mobile terminals is more and more functions and smaller and smaller volumes. However, mobile terminals with more functions must use more electronic devices, which will inevitably lead to larger volumes of mobile terminals. [0004] Taking the data card holder of a mobile phone as an example, an existing dual-mode mobile phone needs to be equipped with two cards, and each card is electrically connected to the circuit on the main circuit board through a data card holder. In the prior art...
