As shown in Figure 1a, the terminal 01 also includes a card holder 40. After the communication card is placed in the card holder 40, the card holder 40 carries the communication card and inserts it into the card slot 1121 in the direction indicated by the arrow, so that the communication card can be inserted into the set In the card socket on the circuit board 30. The communication card is electrically connected to the circuit board 30 in the terminal 01 through the shrapnel on the card socket to complete signal transmission.

Among them, the communication card can be, for example, a subscriber identification module (SIM) card. The SIM card can be a standard SIM card, a micro sim card (SIM card), or a nano sim card (micro SIM card). ). Of course, the communication card may also be a secure digital memory card (SD card).

Hereinafter, the structure of the card tray 40 will be described in detail with reference to the accompanying drawings.

As shown in Figure 2a, the card tray 40 includes a card tray 41 and a frame 42. The frame 42 is fixedly connected to the card tray 41. The frame 42 is arranged on the periphery of the card tray 41. The frame 42 can wrap around the edge of the card tray 41. , The frame 42 can also be around at least the edge of the card tray 41.

As shown in Fig. 2b (a cross-sectional view along the B1-B2 direction in Fig. 2a), the card tray 41 and the frame 42 are enclosed as a card slot 43, the frame 42 is used as the wall of the card slot 43, and the card tray 41 is used as the card slot 43 The bottom of the groove.

Among them, the shape of the card slot 43 is compatible with the shape of the communication card to be installed, and the size of the card slot 43 is compatible with the size of the communication card to be installed.

The communication card to be installed may be the aforementioned SIM card or SD card. Depending on the shape and size of the communication card to be installed, the shape and size of the card slot 43 enclosed by the card tray 41 and the frame 42 are also different. The shape of the card slot 43 is compatible with the shape of the communication card to be installed, and the size of the card slot 43 is compatible with the size of the communication card to be installed, which means that the position of the communication card to be installed is fixed in the slot 43. Will not shake. In other words, after the communication card to be installed is placed in the card slot 43, the outer contour of the communication card to be installed can contact the wall of the card slot 43 (that is, the surface of the frame 42 facing the card slot 43).

As shown in FIG. 2 a, the frame 42 includes a first frame 421, and the first frame 421 includes a first through hole 4211 and a first side wall 4212 located between the first through hole 4211 and the slot 43. The first side wall 4212 has a first protrusion 42121 facing the slot 43.

Wherein, the first frame 421 is a part of the frame 42. Taking the card slot 43 as the rectangle shown in FIG. 2a as an example, the first frame 421 is any one of the four frames surrounding the card slot 43.

Hereinafter, for ease of description, as shown in FIG. 2a, the frame 42 includes a first frame 421, a second frame 422, a third frame 423, and a fourth frame 424 as an example for description. The second frame 422 is disposed opposite to the first frame 421, the third frame 423 and the fourth frame 424 are disposed opposite to each other, and the third frame 423 and the fourth frame 424 are connected to the first frame 421 and the second frame 422, respectively.

On the basis of the above structure, as shown in FIG. 2b, the frame body 42 further includes an inclined surface a facing the card slot 43 (in FIG. 2b, the inclined surface a is provided on the first frame 421 as an example), the inclined surface a and the card tray The angle α between the surfaces b of 41 is an acute angle.

Wherein, the installation position of the inclined surface a is not limited, and the surface of the frame 42 facing the slot 43 may include the inclined surface a. Therefore, the inclined surface a may belong to the surface of the first frame 421 facing the slot 43, the surface of the second frame 422 facing the slot 43, or the surface of the third frame 423 facing the slot 43, or it can belong to the first frame 423. The four frames 424 face the surface of the slot 43.

Taking the surface of the first frame 421 facing the slot 43 including the above-mentioned inclined surface a as an example, in a possible embodiment, the surface of the first frame 421 facing the slot 43 is divided into two parts, one part (for example, the first protrusion 42121 The surface facing the card slot 43) serves as the above-mentioned inclined surface a, and the included angle α between the surface b of the card tray 41 and the card tray 41 is an acute angle. The angle between the other part and the surface b of the card tray 41 is a right angle or an obtuse angle. In another possible embodiment, the first frame 421 faces the surface of the card slot 43, the entire surface is used as the above-mentioned inclined surface a, and the included angle α between the surface b of the card tray 41 is an acute angle.

As shown in FIG. 2c, when the card slot 43 is installed with the communication card 44 to be installed, the first protrusion 42121 will move toward the first through hole 4211, and the first side wall 4212 will be slightly deformed.

It can be understood that, in order to support the communication card 44 to be installed, after the first protrusion 42121 moves toward the first through hole 4211, the first side wall 4212 will not be broken. Based on this, in some embodiments, the material constituting the first side wall 4212 is a plastic material. Plastic material refers to a material that is deformed significantly without being destroyed under the action of external force.

In addition, it can be understood that the frame 42 and the card tray 41 are fixedly connected, but when the communication card is installed, the first protrusion 42121 will move toward the first through hole 4211. Therefore, relative movement between the first protrusion 42121 and the card tray 41 is possible.

In the following, for ease of description, the communication card 44 to be installed is a SIM card as an example for schematic description.

In the process of using the card tray 40, after the SIM card is placed in the card slot 43, the card tray 40 carries the SIM card from the card slot 1121 into the terminal 01, and realizes a communication connection with the circuit board 30. As shown in Figure 3a, when the card tray 40 is taken out along the width direction Y, when the card tray 40 is partially pulled out of the terminal housing assembly 10, the elastic pieces on the card socket will be inside the terminal (card The rear part of the holder 40 applies elastic force to the SIM card, and the direction of the elastic force is along the thickness direction Z, causing the part of the SIM card located outside the housing assembly 10 to lift up and eject the card holder 40. However, the head of the card tray 40 opposite to the tail does not have the housing assembly 10 to apply pressure to the SIM card to press the SIM card against the card tray 40, which may cause the SIM card to be ejected from the card tray 40 by elastic force.

Based on the card holder 40 provided by the embodiment of the present application, as shown in FIG. 2c, when the card slot 43 is installed with the communication card 44 to be installed, the first protrusion 42121 will move toward the first through hole 4211. In other words, the communication card 44 to be installed will expand the card slot 43 to a certain extent. In this case, when the SIM card is installed in the card slot 43, the wall of the card slot 43 (that is, the frame 42 of the card tray 40) will apply a clamping force to the SIM card, and the direction of the clamping force is as follows The direction indicated by the arrow in FIG. 2c ensures that the SIM card is firmly placed in the card slot 43. The clamping force applied by the card slot 43 to the SIM card is the resistance of the SIM card ejecting from the card slot 43. Therefore, the risk of ejecting the SIM card from the card tray 40 can be reduced, and the user experience can be improved.

In addition, because the frame 42 includes an inclined surface a facing the card slot 43, and the included angle α between the inclined surface a and the surface b of the card tray 41 is an acute angle. As shown in Figure 3b, when the elastic force exerted by the shrapnel on the far right side of the SIM card (located inside the terminal) causes the SIM card to have a tendency to bounce off, the SIM card is subjected to the pressure exerted by the inclined plane a, which can prevent the SIM card from popping up. The risk of ejecting the SIM card from the tray 40 can be further reduced.

Furthermore, a part of the first frame 421 on the frame 42 directly serves as an elastic arm that can move relative to the card tray 41, without adding additional parts, and the structure is simple.

Hereinafter, the structure of the card tray 40 provided in the embodiment of the present application is illustrated with several specific embodiments.

Therefore, in order to make the card tray 40 suitable for different types of terminals. As shown in Figures 5a and 5b (cross-sectional views along the D1-D2 direction in Figure 5a), in another possible embodiment, the card tray 41 has at least one second through hole 411 (in Figure 5a, the card tray There is a second through hole 411 on 41 as an example). So that when the elastic sheet is located on the side of the card tray 41 away from the card slot 43, the elastic sheet can pass through the second through hole 411 to be electrically connected to the SIM card.

In addition, by providing the second through hole 411 on the card tray 41, when the SIM card is removed from the tray 40, the SIM card can be lifted from the second through hole 411 to facilitate the removal of the SIM card.

As shown in FIG. 5a, the frame 42 includes a first frame 421, a second frame 422, a third frame 423, and a fourth frame 424.
