Chinese patent application number: 201520627515.4, discloses a SIM card holder, including an insulating body and a card tray, the insulating body includes a first shell and a second shell that are fastened up and down, and the card tray is placed between the first shell and the second shell. The two shells are enclosed to form a storage slot, the card tray is provided with a first card slot for placing a Micro-SIM card, and the back of the first card slot is provided with a second card slot for placing a TF card or Nano-SIM card , the shape of the second card slot in the length direction is the same as that of the TF card and the shape of the second card slot in the width direction is the same as that of the Nano-SIM card.

The structure of the above-mentioned patent is complicated, and it is easy to cause poor contact due to vibration when reading the card, and the card body falls off, resulting in data loss.

Contents of the invention

The object of the present invention is to overcome the above-mentioned defects of the prior art, and provide a simple structure, reasonable design, which can prevent poor contact and data loss caused by abnormal withdrawal of the card body.

In order to achieve the above object, the technical solution provided by the present invention is as follows: a MicroSIM card holder that prevents the card body from exiting abnormally, including a base, a shell and a card tray, a connecting terminal is provided on the base, and a self-elastic device is provided on one side of the base. The self-elastic device includes a pull rod, a spring and a slider. The side of the slider is provided with a shrapnel, the side of the housing is provided with a fixed stop corresponding to the shrapnel, and the side of the card holder is provided with a gap corresponding to the shrapnel.

Further, a cavity is provided between the base and the shell, and the card tray is movably connected in the cavity.

Further, there is a Micro SIM card slot in the middle of the card tray.

The advantages of the present invention are: simple structure, by setting a gap on the card holder, a card locking hardware shrapnel on the slider, and a stopper on the shell, when the Micro SIM card is in the card reading state, the gap, The metal shrapnel and the stopper form the card locking structure, which prevents the card body from being shaken and causing poor contact, and the card body falls off, resulting in data loss.

detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

As shown in Fig. 1-Fig. 4, a kind of Micro SIM card holder that prevents the card body from exiting abnormally according to the present invention includes a base 1, a shell 2 and a card tray 3, the base 1 is provided with a connecting terminal 11, and the base 1 A self-elastic device 12 is provided on one side, and the self-elastic device 12 includes a pull rod 121, a spring 122 and a slider 123. The side of the slider 123 is clamped with a metal shrapnel 4, and the side of the shell 2 is bent downwards at 4 places corresponding to the shrapnel. The stopper 5 is fixed, and a notch 6 is provided on the side of the card holder 3 corresponding to the elastic piece 4 .

Further, a cavity 7 is provided between the base 1 and the shell 2, and the card tray 3 is movably connected in the cavity 7.

Further, a Micro SIM card slot 31 is opened in the middle of the card tray 3 .

Further, the Micro SIM card is placed in the Micro SIM card slot 31 opened in the middle of the card tray 3, inserted into the cavity 7 between the shell 2 and the base 1, and the slider 123 moves along with the insertion depth of the card tray 3 , when the card tray 3 is pushed to the bottom of the cavity 7 and no force is applied, the slider 123 rebounds and locks tightly, and the shrapnel 4 on the side of the slider 123 just engages with the notch 6 on the side of the card tray 3, and the shrapnel 4 is just blocked by the fixed stopper 5 bent downwards on the shell 2. The fixed stopper 5 prevents the shrapnel 4 from moving to the right under force and causing the card tray 3 to slide out. The shrapnel 4 and the notch 6 and the fixed stopper Block 5 three forms the lock card structure, prevents the card body from withdrawing abnormally.

Furthermore, when it is necessary to take out the Micro SIM card body, it is only necessary to push the card tray 3 to the bottom of the cavity 7 again, the slider 123 of the self-elastic device 12 rebounds and drives the card tray 3 to rebound to the initial position, and the shrapnel 4 is not in place. Blocked by the fixed block 5 provided on the housing 2, the shrapnel 4 is directly moved to the right due to its own metal elastic force when stressed, and the card holder 3 is directly taken out under the action of an external force.

What has been described above is only the principles and preferred embodiments of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the principle of the present invention, which should also be regarded as belonging to the protection scope of the present invention.
