[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 3 In this embodiment, a tray-type TF card holder with switch detection includes a plastic body 1, on which an adjustment and mounting mechanism is provided.

[0022] See also Figure 1 、 Figure 2 and Figure 3 The adjustment and installation mechanism includes a card block 2 fixedly mounted on the outside of the plastic body 1. There are four card blocks 2, and the card blocks 2 are distributed on both sides of the plastic body 1 in a group of two. A signal pin 3 is provided on the bottom inner wall of the plastic body 1, and a switch key 4 is provided on the inner bottom wall of the plastic body 1. A docking seat 5 is fixedly mounted on the inner bottom wall of the plastic body 1, and a rotating piece 6 is sleeved on the top of the docking seat 5. The top of the plastic body 1 is slidably connected to a push rod 7 that abuts against the rotating piece 6. When the card needs to be ejected, pushing the push rod 7 can drive the rotating piece 6 to rotate, thereby pushing the card out.

[0023] Among them, the top of the plastic body 1 is movably connected with the shell 8, and a card slot is provided on the shell 8, and the position and specifications of the card slot are adapted to the card block 2, so that the plastic body 1 and the shell 8 can be conveniently assembled and used through the card block 2 and the card slot. A card tray 9 is movably inserted on the opposite side of the plastic body 1 and the shell 8, and a through hole is provided inside the rotating piece 6. The rotating piece 6 is rotatably connected to the docking seat 5 through the through hole, so that when the push rod 7 pushes the rotating piece 6, the rotating piece 6 can rotate on the docking seat 5, thereby abutting and moving the card tray 9 to withdraw it from the inside of the plastic body 1.

[0024] Among them, a limit block 10 is fixedly installed on the left side of the card tray 9, and a card body 11 is movably placed on the top of the card tray 9. There are multiple signal pins 3, and the signal pins 3 are evenly distributed on the inner bottom wall of the plastic body 1, which is convenient for contact adaptation with the inserted card body 11 through the signal pins 3, thereby transmitting data. An adjustment component is provided on the inner top wall of the shell 8.

[0025] In this embodiment, the adjustment component includes a limit seat 12 fixedly mounted on the inner top wall of the shell 8, a spring 13 fixedly mounted on the inner top wall of the limit seat 12, a movable block 14 slidably connected to the inner wall of the limit seat 12 fixedly mounted on the bottom of the spring 13, an abutment plate 15 extending to the outside of the limit seat 12 fixedly mounted on the bottom of the movable block 14, a sliding groove is provided on the inner wall of the limit seat 12, a first through hole is provided at the bottom of the limit seat 12, the movable block 14 is slidably connected to the limit seat 12 through the sliding groove, and the abutment plate 15 extends to the bottom of the limit seat 12 through the first through hole, so that the movement of the movable block 14 is conveniently limited by the sliding groove, so that its movement remains stable, and the abutment plate 15 can be moved and adjusted through the first through hole.

[0026] It should be noted that the tray-type TF card holder with switch detection, through the provided adjustment installation mechanism, with the mutual cooperation between the various structures on the plastic body 1, can not only stably install and use the TF card to avoid poor contact, but also conveniently eject it after use. At the same time, the switch key 4 is used to monitor its status while the TF card is inserted or ejected, avoiding equipment failure caused by the inability to detect the TF card status. In addition, the switch of this product adopts one-time molding technology to stamp the switch detection spring and the signal spring into a set of molds, which greatly improves product stability and assembly efficiency.

[0027] The working principle of the above embodiment is:

[0028] When using the tray-type TF card holder with switch detection, first dock the shell 8 with the plastic body 1. After the shell 8 is installed, the pressure piece inside the shell 8 contacts the switch key 4, thereby realizing signal communication. Then, the card block 2 and the card slot are clamped and fixed. Then, the card body 11 is placed on the card tray 9, and the limit block 10 is pushed to insert the card tray 9 between the plastic body 1 and the shell 8. As the card tray 9 is inserted, the card body 11 contacts the signal pin 3 and also contacts the switch key 4. This realizes the monitoring of the insertion of the card tray 9. When the card body 11 enters, the abutment plate 15 at the bottom of the limit seat 12 rises to compress the spring 13. After the card body 11 is fully inserted, the abutment plate 15 is driven by the elastic force of the spring 13 to abut and fix the card body 11. When the card body 11 needs to be removed, the card removal needle is inserted into the socket on the limit block 10 to push the push rod 7 to slide, so that the push rod 7 abuts against the rotary plate 6, so that the rotary plate 6 pushes the card tray 9 to pop out, thereby removing the card body 11.
