[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-5 , a TF card socket that can be quickly positioned, including a mounting base 1 and a TF card body 2; the mounting base 1 includes a card slot 15, a chute 12 and a contact seat 3; the chute 12 is provided with a positioning block 11, a first telescopic rod 13 and a first spring 14; the contact seat 3 is provided with a second telescopic rod 32 and a second spring 33; the card slot 15 is located inside the mounting base 1, the chute 12 is located on the side wall of the card slot 15, the contact seat 3 is located at the bottom of the card slot 15, the first telescopic rod 13 is located on the side walls of the chute 12 near both sides of the mounting base 1, the first spring 14 is sleeved on the first telescopic rod 13, the second telescopic rod 32 is provided at four corners of the lower surface of the contact seat 3, and the second spring 33 is sleeved on the second telescopic rod 32.

[0023] The positioning block 11 is reset by the first telescopic rod 13 and the first spring 14 in the chute 12. When the TF card body 2 is inserted into the card slot 15, the TF card body 2 is clamped on the side. When the front end of the TF card body 2 contacts the inclined surface of the contact seat 3, the contact seat 3 is driven to move downward. When the TF card body 2 is completely inserted, the contact seat 3 moves upward under the action of the second spring 33, and the contacts 31 on the contact seat 3 are in close contact with the pins on the TF card body 2, clamping the TF card body 2 in the vertical direction.

[0024] Both of the first springs 14 are fixedly connected to the side wall of the chute 12, and the other end of the first spring 14 abuts against the positioning block 11. When the TF card body 2 is inserted into the card slot 15, it drives the positioning block 11 to displace laterally, driving the first spring 14 to be compressed.

[0025] When the first telescopic rod 13 and the first spring 14 are compressed, the top of the positioning block 11 is not higher than the notch of the chute 12, which is convenient for the TF card body 2 to be inserted into the card slot 15 without being stuck by the positioning block 11.

[0026] The upper surface of the contact seat 3 is provided with contacts 31, and one side of the contact seat 3 close to the input end is provided with an inclined surface, which is convenient for the TF card body 2 to be inserted into the card slot 15 and drive the contact seat 3 to move downward.

[0027] All four of the second springs 33 are fixedly connected to the lower surface of the contact seat 3, making the movement of the contact seat 3 more stable and the force more evenly distributed.

[0028] When the second spring 33 is compressed, the upper surface of the contact seat 3 is not higher than the upper surface of the card slot 15, which is convenient for the TF card body 2 to be inserted into the card slot 15 without being stuck by the contact seat 3.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
