Description

Technical Field

[0001] This utility model relates to the field of microcontroller programming technology, and in particular to a microcontroller programming interface device with a foolproof design. Background Technology

[0002] Microcontroller programming refers to the process of using a specific programming language to control and operate the internal resources (including registers, memory, input / output interfaces, etc.) of a microcontroller to achieve specific functions. A microcontroller is a miniature computer that integrates a central processing unit (CPU), memory, input / output interfaces, and other components. Through programming, it can perform tasks such as data processing, logic control, signal acquisition and output. Microcontroller programming is widely used in many fields such as industrial control, smart homes, automotive electronics, and medical equipment. It can endow various devices with intelligent control capabilities, enabling them to meet different working requirements. It plays a key role in modern electronic systems, and the interface device is an important component of the microcontroller.

[0003] A search revealed Chinese Patent Publication No. CN217882144U, which discloses an interface device comprising: a first end having a first interface surface and a first protrusion on one side of the first interface surface; and a second end having a second interface surface adapted to the shape of the first interface surface and a second protrusion on one side of the second interface surface, such that when the second interface surface is connected to the first interface surface, the first protrusion and the second protrusion are respectively located on both sides of the connection. The interface device according to this invention allows for a tighter connection between the first end and the second end, which is beneficial for ensuring the stability of signal transmission.

[0004] However, existing interface devices rely solely on differences in plug shape for foolproof protection, which makes them prone to misinsertion. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a single-chip programming machine interface device with a foolproof design, which aims to improve the problem that the existing interface devices rely solely on the difference in plug shape for foolproof design, which makes it easy to misinsert.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A single-chip programming machine interface device with a foolproof design includes a female interface, a male plug block provided on the inner wall of the female interface, a plug fixedly connected to the outer wall of the male plug block, a socket provided inside the female interface, a limiting block one fixedly connected inside the female interface, a limiting block two fixedly connected to the lower surface of the limiting block one, a return spring provided inside the limiting block two, a limiting component one provided on the outer wall of the return spring, a return tension spring provided inside the limiting block one, a limiting component two provided on the outer wall of the return tension spring, the limiting component two being connected to the limiting block one, and the limiting component two being connected to the limiting component one.

[0007] The above technical solution works as follows: by inserting the plug into the socket, the male plug is embedded in the female interface. The first limiting component is operated to move out of the second limiting block and press down. Then, the first limiting component drives the return spring to produce elastic deformation, and the first limiting component releases the displacement restriction on the second limiting component. The return spring resets and pulls the second limiting component into the first limiting block. Since the second limiting component is connected to the locking block, the locking block enters the first limiting block simultaneously and disengages from the male plug. At this time, the male plug can be pulled out from the female interface. This achieves the effect of ensuring that the male plug is firmly restricted inside the female interface, preventing the male plug from accidentally disengaging, ensuring the stability of the interface device, and preventing incorrect installation direction of the male plug.

[0008] As a further description of the above technical solution: The limiting component includes a push block, the interior of which is disposed on the outer wall of the reset spring, and a rotating block is fixedly connected to the outer wall of the push block.

[0009] The above technical solution involves applying a pulling force to the rotating block, causing the push block 1 to slide under the influence of the rotating block, ultimately causing the push block 1 to detach from below the push block 2.

[0010] As a further description of the above technical solution: The outer wall of the push block 1 is slidably connected to the inner wall of the limiting block 2, and the outer wall of the rotating block is disposed inside the limiting block 2.

[0011] Through the above technical solution: the limiting block two restricts the displacement range of the push block one, the rotating block provides driving force for the rotation of the push block one, and at the same time, the limiting block two plays a positioning role in the installation position of the rotating block.

[0012] As a further description of the above technical solution: The limiting component two includes a push block two, the interior of which is fixedly connected to the outer wall of the reset spring. A locking block is fixedly connected to the outer wall of the push block two. A locking groove is opened inside the male end insertion block. The outer wall of the locking block is located inside the locking groove and inside the male end insertion block.

[0013] With the above technical solution: after push block one disengages from below push block two, the reset spring drives push block two to slide within limit block one. Then the locking block moves with push block two and disengages from the locking slot. At this time, the male end plug can be removed from the female end interface.

[0014] As a further description of the above technical solution: The outer wall of the second push block is slidably connected to the inner wall of the first limiting block, and the outer wall of the second push block is disposed on the outer wall of the first push block.

[0015] Through the above technical solution: the limiting block one is used to define the displacement range of the push block two, and the push block one is used to restrict the movement of the push block two.

[0016] As a further description of the above technical solution: The outer wall of the plug is located inside the female end interface, and the outer wall of the plug is located inside the socket.

[0017] The above technical solution involves inserting a plug into a socket to connect the internal circuitry of the programming machine.

[0018] As a further description of the above technical solution: The male end plug has a connecting wire inside, and a connecting block one is fixedly connected to the outer wall of the connecting wire. The outer wall of the male end plug has a connecting block two, and a connecting bolt is threaded inside the connecting block one.

[0019] The above technical solution involves placing connecting block one and connecting block two in corresponding positions to align them. Both connecting block one and connecting block two have grooves inside. After alignment, the grooves are connected to form a through hole. Then, the connecting bolt is inserted into the through hole to fix connecting block one and connecting block two. After the connection is completed, the shielding structure formed by connecting block one and connecting block two will cover the connection part between the male terminal plug and the connecting wire, thereby preventing external dust and impurities from entering the connection area, preventing short circuits, and ensuring the stable operation of the programmer.

[0020] As a further description of the above technical solution: The outer wall of connecting block one is disposed on the outer wall of connecting block two, the outer wall of connecting bolt is threadedly connected to the inner wall of connecting block one, and the outer wall of connecting bolt is threadedly connected to the inner wall of connecting block two.

[0021] The above technical solution uses connecting bolts to connect connecting block one and connecting block two.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by inserting the plug into the socket so that the male plug is inserted into the inside of the female interface, and then pulling the rotating block, the first push block slides inside the second limiting block under the drive of the rotating block, thereby fixing the male plug inside the female interface, preventing the male plug from accidentally coming out, maintaining the stability of the interface device, and avoiding the installation direction deviation of the male plug.

[0023] 2. In this utility model, by placing connecting block one and connecting block two correspondingly to align their positions, both connecting block one and connecting block two have grooves inside. After alignment, the grooves overlap to form a through hole. Then, the connecting bolt is inserted into the through hole, thereby preventing dust and impurities from entering the connection area between the male plug and the connecting wire, preventing short circuits, and ensuring the stable operation of the programming machine.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a single-chip programming machine interface device with a foolproof design. The inner wall of the female interface 1 is provided with a male plug 2, and the outer wall of the male plug 2 is fixedly connected with a plug 3. The female interface 1 is provided with a socket 4. The female interface 1 is fixedly connected with a limiting block 5. The lower surface of the limiting block 5 is fixedly connected with a limiting block 6. The limiting block 6 is provided with a reset spring 7. The outer wall of the reset spring 7 is provided with a limiting component 18. The limiting block 5 is provided with a reset tension spring 11. The outer wall of the reset tension spring 11 is provided with a limiting component 19. The limiting component 19 is connected to the limiting block 5 and the limiting component 18. Specifically, by inserting the plug 3 into the socket 4, the male plug 2 is inserted into the female interface 1. Then, the limiting component 18 is rotated to pull it away from the inside of the limiting block 2 6. Subsequently, the limiting component 18 is pressed down, and the return spring 7 undergoes elastic deformation under the action of the limiting component 18. At the same time, the limiting component 18 no longer restricts the displacement of the limiting component 2 19. Then, the return spring 11 resets and pulls the limiting component 2 19 into the inside of the limiting block 5. Since the limiting component 2 19 is fixedly connected to the locking block 12, the locking block 12 enters the limiting position synchronously under the action of the limiting component 2 19. Inside block 5, at this time, the locking block 12 disengages from the inside of the male plug 2, and the male plug 2 can be pulled out from the inside of the female interface 1. Then, pull the rotating block 9 to reset the rotating block 9, and the locking block 12 is locked inside the female interface 1. The groove on one side of the male plug 2 can enter the inside of the female interface 1 and be locked by the locking block 12 to prevent the male plug 2 from being inserted in the wrong position. This can ensure that the male plug 2 can be firmly restricted inside the female interface 1, avoid the male plug 2 from accidentally disengaging, ensure the stability of the interface device, and prevent the male plug 2 from being installed in the wrong direction.

[0028] Reference Figure 3 The limiting component 18 includes a push block 8, the interior of which is disposed on the outer wall of the reset spring 7, and a rotating block 9 is fixedly connected to the outer wall of the push block 8. Specifically, when the rotating block 9 is pulled, since the rotating block 9 is fixedly connected to the push block 1 8, the push block 1 8 slides inside the limiting block 2 6 under the drive of the rotating block 9, and then the push block 1 8 disengages from the lower side of the push block 2 10.

[0029] Reference Figure 3 The outer wall of push block 1 8 is slidably connected to the inner wall of limit block 2 6, the outer wall of push block 1 8 is slidably connected to the inner wall of limit block 1 5, and the outer wall of rotating block 9 is set inside limit block 2 6. Specifically, the second limiting block 6 is used to limit the displacement range of the first pushing block 8, the rotating block 9 is used to drive the first pushing block 8 to rotate, and the second limiting block 6 is used to limit the placement position of the rotating block 9.

[0030] Reference Figure 3 and Figure 4 The second limiting component 19 includes a second push block 10, which is internally fixedly connected to the outer wall of the reset spring 11. A locking block 12 is fixedly connected to the outer wall of the second push block 10. A locking groove 13 is opened inside the male end insertion block 2. The outer wall of the locking block 12 is located inside the locking groove 13 and inside the male end insertion block 2. The outer wall of the second push block 10 is slidably connected to the inner wall of the first limiting block 5 and is located on the outer wall of the first push block 8. Specifically, when push block 18 disengages from the underside of push block 210, the reset spring 11 drives push block 210 to slide inside limit block 15. Since the locking block 12 is fixedly connected to push block 210, the locking block 12 disengages from the inside of the locking slot 13 under the drive of push block 210. At this time, the male end plug 2 can be pulled out from the inside of the female end interface 1.

[0031] Reference Figure 2 The outer wall of plug 3 is located inside the female terminal interface 1, and the outer wall of plug 3 is located inside the socket 4; Specifically, the internal circuitry of the programmer is connected by inserting plug 3 into the socket 4.

[0032] Reference Figure 4 The male end plug 2 has a connecting wire 14 inside, and a connecting block 15 is fixedly connected to the outer wall of the connecting wire 14. The outer wall of the male end plug 2 has a connecting block 2 16. The connecting block 15 has a connecting bolt 17 threaded inside. The outer wall of the connecting block 15 is set on the outer wall of the connecting block 2 16. The outer wall of the connecting bolt 17 is threaded to the inner wall of the connecting block 15. The outer wall of the connecting bolt 17 is threaded to the inner wall of the connecting block 2 16. Specifically, by aligning and placing connecting block 15 and connecting block 2 16, and then inserting connecting bolt 17 into the grooves opened inside connecting block 15 and connecting block 2 16, the grooves are aligned and form through holes. Then, connecting bolt 17 enters the through holes to connect connecting block 15 and connecting block 2 16. At this time, the connection between male plug 2 and connecting wire 14 is covered by the shielding structure formed by connecting block 15 and connecting block 2 16, thereby preventing external dust and impurities from entering the connection between male plug 2 and connecting wire 14, avoiding short circuits, and ensuring the normal operation of the programming machine.

[0033] Working principle: By inserting plug 3 into socket 4, the male plug 2 is inserted into the female interface 1. Then, the rotating block 9 is pulled. Since the rotating block 9 is fixedly connected to push block 8, push block 8 slides inside the limiting block 6 under the action of the rotating block 9. Then, the return spring 7 undergoes elastic deformation under the action of push block 8, and push block 8 disengages from the underside of push block 10. Subsequently, the return spring 11 returns to its original position. The return spring 11 drives push block 10 to slide inside the limiting block 5. Then, the locking block 12 locks push block 10. Driven by the action, the male plug 2 can be pulled out from the inside of the female interface 1. Then, the rotating block 9 is pulled to reset the rotating block 9. The locking block 12 is locked inside the female interface 1. The groove on one side of the male plug 2 can enter the inside of the female interface 1 and be locked by the locking block 12 to prevent the male plug 2 from being inserted in the wrong position. This can fix the male plug 2 inside the female interface 1, prevent the male plug 2 from accidentally coming out, maintain the stability of the interface device, and avoid the male plug 2 from having a deviation in the installation direction. By placing connecting block 15 and connecting block 2 16 correspondingly to align their positions, and by aligning the grooves inside both connecting block 15 and connecting block 2 16 to form a through hole after alignment, connecting bolt 17 is inserted into the through hole to connect connecting block 15 and connecting block 2 16. After connection, the shielding structure formed by connecting block 15 and connecting block 2 16 will cover the connection part between male plug 2 and connecting wire 14, thereby preventing dust and impurities from entering the connection area between male plug 2 and connecting wire 14, preventing short circuits, and ensuring stable operation of the programming machine.
