[0026] In one embodiment, as Figure 1-7 shown, an IO board that is convenient to connect includes a circuit board 1. In the middle of the top surface of the circuit board 1, an IO board body 2 is placed. On the left and right sides of the top surface of the circuit board 1, connection bars 3 are fixedly connected. A first connecting rod 4 is movably sleeved in the middle of each connection bar 3. In the middle of the side of each connection bar 3 away from the IO board body 2, a connection cylinder 5 is fixedly connected. One end of the first connecting rod 4 away from the IO board body 2 is movably sleeved in the connection cylinder 5. On the end face of the first connecting rod 4 away from the IO board body 2, a fixed block 6 is fixedly connected. Slots 7 are opened on the front and rear sides of the fixed block 6. A fixing component 8 is installed in the connection cylinder 5. On the end face of the first connecting rod 4 close to the IO board body 2, a connecting plate 9 is fixedly connected. On the front and rear sides of each connecting plate 9 close to the IO board body 2, clamping blocks 10 are fixedly connected. The four corners of the IO board body 2 are respectively inserted into the inner sides of the adjacent clamping blocks 10. In the middle of the top surface of each connecting plate 9, a pressing plate 11 is fixedly connected. The bottom surfaces of the two pressing plates 11 are respectively in contact with the left and right sides of the top surface of the IO board body 2.

[0027] In order to be able to fix the fixed block 6, thereby ensuring the stability of the clamping block 10 and the pressing plate 11 in fixing the IO board body 2, the fixing assembly 8 includes two second connecting rods 81. The two second connecting rods 81 are respectively movably sleeved on the front and rear sides of the connecting cylinder 5. The end faces of the two second connecting rods 81 on the facing sides are fixedly connected with inserting blocks 82. The side of the inserting block 82 facing the fixed block 6 is inclined. The facing sides of the two inserting blocks 82 are respectively inserted into the adjacent slots 7. A first spring 83 is sleeved on the surface of each second connecting rod 81. One end of the first spring 83 is fixedly connected with the inserting block 82, and the other end of the first spring 83 is fixedly connected with the side surface of the inner wall of the connecting cylinder 5. The end face of the second connecting rod 81 on the side away from the inserting block 82 is fixedly connected with a pulling block 84, and a pulling ring 85 is fixedly connected to the side of the pulling block 84 away from the second connecting rod 81.

[0028] In order to prevent the inserting block 82 from rotating, resulting in the inclined surface of the inserting block 82 no longer facing the fixed block 6, limiting blocks 86 are fixedly connected to the separating sides of the bottoms of the two inserting blocks 82. A first guiding rod 87 is movably sleeved in the middle of the two limiting blocks 86. The front and rear end faces of the first guiding rod 87 are fixedly connected to the front and rear sides of the inner wall of the connecting cylinder 5 and near the bottom respectively.

[0029] In order to electrically connect the IO board body 2 to the circuit board 1, connecting leads 12 are fixedly connected to the front and rear sides of the IO board body 2. Fixing strips 13 are fixedly connected to the front and rear sides of the top surface of the circuit board 1. A lead slot 14 is opened on the side of the fixing strip 13 close to the IO board body 2. The connecting leads 12 are inserted into the lead slot 14.

[0030] In order to enable the clamping block 10 and the pressing plate 11 to automatically move away from the IO board body 2 and automatically release the fixing of the IO board body 2 after the fixing of the fixed block 6 is released, a pushing block 15 is fixedly connected to the end face of the first connecting rod 4 on the side away from the IO board body 2. A second spring 16 is sleeved on the middle of the surface of the first connecting rod 4. One end of the second spring 16 is fixedly connected with the connecting strip 3, and the other end of the second spring 16 is fixedly connected with the connecting plate 9.

[0031] In order to prevent the connecting plate 9 from swinging during movement, resulting in the clamping block 10 and the pressing plate 11 being unable to accurately clamp and press on the IO board body 2, second guiding rods 17 are fixedly connected to the front and rear sides of the side of the connecting plate 9 away from the IO board body 2. The ends of the two second guiding rods 17 away from the connecting plate 9 are respectively movably sleeved on the front and rear sides of the connecting strip 3.

[0032] In order to facilitate the positioning and placement of the IO board body 2 on the circuit board 1, a positioning groove 18 is opened in the middle of the top surface of the circuit board 1. Positioning blocks 19 are fixedly connected to the left and right sides of the bottom surface of the IO board body 2. The positioning blocks 19 are inserted into the positioning groove 18.

[0033] In order to be able to connect and fix the lead 12, lead fastening plates 20 are provided on both the front and rear sides of the IO board body 2. The lead fastening plates 20 are arranged between the IO board body 2 and the fixing strip 13. A plurality of lead fixing members 21 are fixedly connected to the bottom surface of the lead fastening plate 20. The number of lead fixing members 21 is equal to the number of lead grooves 14, and their positions and shapes correspond one by one. The lead fixing members 21 are inserted into the lead grooves 14. Insertion holes 22 are formed on both the left and right sides of the lead fastening plate 20. Plug rods 23 are fixedly connected to the facing surfaces of the left and right relatively clamping blocks 10. The plug rods 23 are inserted into the adjacent insertion holes 22.

[0034] In order to facilitate the positioning and placement of the lead fastening plate 20 on the fixing strip 13, positioning plates 24 are fixedly connected to both the left and right sides of the side of the fixing strip 13 away from the IO board body 2. The facing surfaces of the two positioning plates 24 are respectively in contact with the left and right sides of the fixing strip 13.

[0035] Working principle: When the present utility model is in use, first place the IO board body 2 on the circuit board 1, insert the positioning block 19 into the positioning groove 18 to position the IO board body 2, and connect the connecting lead 12 into the lead groove 14. Then place the lead fastening plate 20 on the top of the lead groove 14, so that the lead fixing members 21 fix the connecting lead 12. Then push the push block 15. The push block 15 drives the first connecting rod 4 to move. The first connecting rod 4 drives the connecting plate 9 to move. The connecting plate 9 drives the clamping blocks 10 and the pressing plates 11 to move, so that the four clamping blocks 10 respectively clamp the four corners of the IO board body 2, and the bottom surfaces of the two pressing plates 11 are respectively in contact with the left and right sides of the top surface of the IO board body 2, thereby fixing the IO board body 2. When the first connecting rod 4 moves, it will drive the fixing block 6 to move. The fixing block 6 enters the inside of the connecting cylinder 5. The front and rear sides of the fixing block 6 are respectively in contact with the facing surfaces of the front and rear inserting blocks 82. Since the facing surfaces of the front and rear inserting blocks 82 are inclined surfaces, when the fixing block 6 moves, it will push the two inserting blocks 82 to move away from each other. After the inserting blocks 82 move a certain distance, the first spring 83 will push the inserting blocks 82 to move, so that the inserting blocks 82 are inserted into the slot 7 to lock the fixing block 6, thereby fixing the clamping blocks 10 and the pressing plates 11, ensuring the stable clamping and fixing of the pressing plate 10 and the clamping block 11 on the IO board body 2. At the same time, when the clamping block 10 moves, the plug rod 23 will be inserted into the insertion hole 22 to fix the lead fastening plate 20. When it is necessary to remove the IO board body 2, pull the two pull rings 85 on the front and rear sides. The pull rings 85 drive the second connecting rod 81 to move. The second connecting rod 81 drives the inserting block 82 to move, so that the inserting block 82 is pulled out of the slot 7, thereby releasing the locking of the fixing block 6. At this time, the elastic potential energy of the second spring 16 will pull the connecting plate 9 to move away from the IO board body 2. The connecting plate 9 drives the clamping blocks 10 and the pressing plates 11 to move, thereby releasing the fixing of the IO board body 2, making the disassembly of the IO board body 2 relatively convenient.

[0036] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0037] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed. However, it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
