Description

Technical Field

[0001] This application belongs to the field of industrial communication technology, and in particular relates to an interface switching device for industrial communication control circuits. Background Technology

[0002] In the field of industrial communication control circuits, interface switching equipment is a core component that ensures stable communication and data transmission between various devices. However, the design of traditional interface switching equipment lacks differentiation. Industrial communication interfaces with different functions may be similar in size and shape, leading to mis-insertion by operators. Furthermore, the functional markings on the interface or plug are often blurred, worn, or missing, making it difficult for users to accurately identify the interface type. Mis-insertion may damage the electrical components inside the interface or plug, such as causing short circuits, overloads, or burnout, thereby affecting the normal operation of the equipment.

[0003] Setting a trigger button on the interface or plug requires the user to use a tool (such as a screwdriver) to trigger the button in order to unlock the plug and pull it out, making it cumbersome to disassemble and require external tools to remove. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides an interface switching device for industrial communication control circuits, comprising: microcontroller; An anti-misinsertion mechanism is provided on the microcontroller to match the corresponding shape of the slot according to different interface types, so as to prevent misinsertion of interfaces with different functions; The terminal block is inserted into the anti-misinsertion mechanism and is electrically connected to the microcontroller for connecting at least one wire plug; A positioning mechanism is provided on the terminal block for quick positioning and elastic locking of the wire plug.

[0006] Preferably, the anti-misinsertion mechanism includes multiple four-slot sockets and multiple three-slot sockets, wherein the slots of the four-slot sockets and the three-slot sockets are arrow-shaped or T-shaped.

[0007] Preferably, the arrow slot socket includes a socket body, on which multiple arrow slot structures are arranged side by side.

[0008] Preferably, one end of the arrow groove structure is a dovetail-shaped structure, and the other end is a straight groove-shaped structure.

[0009] Preferably, the T-slot socket includes a socket body, on which multiple T-slot structures are arranged side by side.

[0010] Preferably, the positioning mechanism includes at least two semicircular rings, which are arranged opposite to each other to form a complete ring structure for accommodating the wire plug; An elastic reset component, connected to the semi-circular ring, is used to provide a reset force when the wire plug is inserted or removed; A locking structure is provided between the semicircular ring and the wire plug for rotatably locking the wire plug in the semicircular ring.

[0011] Preferably, the inner surface of the semicircular ring includes an upper conical surface, a connecting surface, and a lower conical surface from top to bottom. The upper conical surface is used to guide the semicircular ring to move outward when the wire plug is inserted, and the connecting surface is used to contact the outer circumference of the wire plug.

[0012] Preferably, the elastic reset assembly includes a round rod, one end of which is fixedly connected to a semi-circular ring via a connecting plate, and the other end of which is slidably connected to a slide bracket via a slider, the slide bracket being mounted on a terminal block; A spring is fitted onto the round rod, and the two ends of the spring are fixed to the connecting plate and the slide bracket, respectively.

[0013] Preferably, the slide bracket is mounted on a fixed plate, and the fixed plate is mounted on a terminal block.

[0014] Preferably, the locking structure includes an L-shaped groove formed on one of the semicircular rings; the L-shaped groove is engaged with a rotating block on the outer circumference of the wire plug.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides an interface switching device for industrial communication control circuits. Through the coordinated configuration of a microcontroller, an anti-misinsertion mechanism, terminal blocks, and a positioning mechanism, the anti-misinsertion mechanism first utilizes slots and plugs of different shapes in the anti-misinsertion mechanism to fundamentally avoid operator misinsertion caused by similar interface shapes or unclear markings, thereby preventing equipment failures such as short circuits, overloads, or burnt-out electrical components caused by misinsertion. Second, during the insertion of the wire plug into the terminal block, the semi-circular ring of the positioning mechanism achieves rapid insertion through a conical guide and automatically resets and locks itself using an elastic reset component, completing the locking without the need for external tools and simplifying disassembly operations. Finally, the rotation locking structure further enhances the anti-vibration and anti-loosening capabilities, ensuring the long-term stability and reliability of the interface connection in high-vibration industrial environments such as mining and metallurgy, thus comprehensively improving the safety, ease of operation, and environmental adaptability of industrial communication control circuits.

[0023] Example like Figure 1-8 As shown, this embodiment provides an interface switching device for industrial communication control circuits, including a microcontroller 1. The microcontroller 1 is provided with an anti-misinsertion mechanism, which includes multiple four-slot sockets 2 and multiple three-slot sockets 3. The multiple four-slot sockets 2 and three-slot sockets 3 are respectively provided with slots of different shapes, and the slots of different shapes are corresponding to the insertion of plugs of corresponding shapes.

[0024] In this embodiment, the design of the anti-misinsertion mechanism is a carefully conceived solution to the critical problem of misinsertion that easily occurs during the connection of industrial communication control circuit interfaces. In complex industrial environments, many devices need to be connected through interfaces to achieve communication and control functions. The shapes and functions of interfaces of different devices vary. If misinsertion occurs, it will not only cause the device to malfunction, but may also cause faults such as short circuits, damage the device, and even affect the stability and safety of the entire industrial production process.

[0025] The microcontroller 1 is provided with a positioning mechanism, which includes a semi-circular ring 5. The conical surface of the semi-circular ring 5 facilitates quick insertion of the wire plug 12. A rotating block 120 is fixedly connected to the wire plug 12. The rotating block 120 rotates into the L-shaped groove 50. A spring 8 is provided on one side of the semi-circular ring 5 to clamp the semi-circular ring 5.

[0026] In this embodiment, after the wire plug 12 is inserted and rotated to fix it, the spring 8 is in a compressed state. It applies a reverse elastic force to the semi-circular ring 5, causing the semi-circular ring 5 to tightly clamp the wire plug 12, preventing it from loosening due to vibration or other external forces. In harsh industrial environments such as mining, strong vibrations are generated during equipment operation. The elastic clamping effect of the spring 8 can effectively ensure the stability of the interface connection and avoid equipment failure and production accidents caused by loosening of the interface.

[0027] Please see Figure 2 and Figure 3 Each of the multiple four-slot sockets 2 is provided with a first arrow slot 20 and a first T-slot 21. An arrow plug 40 and a plug corresponding to the first T-slot 21 are respectively inserted into the first arrow slot 20 and the first T-slot 21.

[0028] Each of the multiple three-slot sockets 3 has a second arrow slot 30 and a second T-shaped slot 31 respectively, and corresponding plugs are inserted into the second arrow slot 30 and the second T-shaped slot 31 respectively.

[0029] In this embodiment, the above structure is not limited to the shape of the first arrow slot 20, the first T-shaped slot 21, the second arrow slot 30 and the second T-shaped slot 31. In practical applications, slots of different shapes can also be set with matching plugs. The main function is to ensure that the matching slots and plugs can be inserted smoothly, thereby avoiding misinsertion.

[0030] Please see Figure 1 The microcontroller 1 is equipped with multiple four-slot sockets 2 and multiple three-slot sockets 3, and the arrow plug 40 is located at the bottom of the terminal block 4.

[0031] The above description of positional relationships is based on existing technology, so we will not go into detail about the connection methods.

[0032] Please see Figure 4 The terminal block 4 has multiple sockets 41, and wire plugs 12 are inserted into the multiple sockets 41 respectively. Multiple fixing plates 11 are fixedly connected to both sides of the sockets 41 and to the top surface of the terminal block 4.

[0033] In this embodiment, the fixing plate 11 plays an important supporting and fixing role. After the wire plug 12 is inserted into the socket 41, the fixing plate 11 can provide a stable support platform for the subsequent installation of the positioning mechanism, ensuring that the positioning mechanism can accurately position and fix the wire plug 12. At the same time, the fixing plate 11 can also enhance the overall structural strength of the terminal block 4, preventing the terminal block 4 from deforming or being damaged during the insertion and removal of the wire. In the metallurgical industry, the operating environment of metallurgical equipment is harsh, and the strength requirements of the interface connection components are high. The design of the fixing plate 11 can meet the needs of the interface connection of metallurgical equipment and ensure the normal operation of the equipment.

[0034] Please see Figure 6 A sliding bracket 10 is fixedly connected to one side of one of the multiple fixed plates 11. A slider 9 is slidably connected to the sliding bracket 10. The slider 9 is fixedly connected to the outer circumferential wall of the round rod 7.

[0035] In this embodiment, the slide bracket 10 allows the slider 9 to slide linearly, thereby causing the slider 9 to drive the round rod 7 to slide linearly.

[0036] Please see Figure 6 One end of the round rod 7 is fixedly connected to a connecting plate 6, and a spring 8 is sleeved on the round rod 7. The spring 8 is located between the connecting plate 6 and the slide bracket 10, and the connecting plate 6 is fixedly connected to the semi-circular ring 5.

[0037] In this embodiment, the semi-circular ring 5 pushes to one side, causing the round rod 7 to move towards the fixed plate 11. At this time, the round rod 7 slides in the fixed plate 11 and the spring 8 is compressed. When there is no external force pushing the semi-circular ring 5, the spring 8 rebounds and causes the round rod 7 and the semi-circular ring 5 to return to their original positions.

[0038] Please see Figure 5 and Figure 7 The two semicircular rings 5 ​​form a complete ring structure. The semicircular rings 5 ​​are in contact with the terminal 4. The inner side of the semicircular ring 5 is composed of an upper conical surface 500, a connecting surface 501 and 502. The connecting surfaces 501 and 502 are in contact with the wire plug 12.

[0039] In this embodiment, the wire plug 12 is vertically inserted into the ring structure. The wire plug 12 first contacts the upper conical surface 500. The wire plug 12 receives a vertical downward force and contacts the upper conical surface 500, which will cause the upper conical surface 500 to move to both sides until the semi-circular ring 5 is fully inserted into the socket 41. Then, the spring 8 rebounds and drives the semi-circular ring 5 to reset.

[0040] Please see Figure 6 and Figure 8One of the semi-circular rings 5 ​​has an L-shaped groove 50. Two-thirds of the L-shaped groove 50 is located on the upper conical surface 500 and the connecting surface 501 and passes through the upper conical surface 500. Two-thirds of the L-shaped groove 50 is a through groove, and the other one-third of the L-shaped groove 50 is provided with a narrow groove. A rotating block 120 is fixedly connected to the outer circumference of the wire plug 12.

[0041] In this embodiment, the rotating block 120 is inserted vertically along the through slot. After being inserted into the through slot, the wire plug 12 is rotated to make the rotating block 120 rotate into the narrow slot to complete the fixation.

[0042] The working principle of this embodiment is as follows: The microcontroller 1 is equipped with multiple four-slot sockets 2 and multiple three-slot sockets 3. The four-slot sockets 2 have a first arrow slot 20 and a first T-slot 21, while the three-slot sockets 3 have a second arrow slot 30 and a second T-slot 31. Corresponding arrow-shaped inserts 40 and other inserts are then inserted into these slots. Only slots and inserts with matching shapes can be successfully inserted, effectively preventing misinsertion.

[0043] When the wire plug 12 needs to be inserted into the socket 41 of the terminal 4, the wire plug 12 is vertically inserted into the complete annular structure composed of two semi-circular rings 5. The wire plug 12 first contacts the upper conical surface 500 on the inner side of the semi-circular ring 5. Under the action of the vertical downward force, the upper conical surface 500 moves to both sides, thereby driving the connecting plate 6 fixedly connected to the semi-circular ring 5 to move. The connecting plate 6 drives the round rod 7 to move towards the fixed plate 11. The round rod 7 slides linearly under the action of the slider 9 and the slide bracket 10. At the same time, the spring 8 is compressed. When the wire plug 12 is fully inserted into the socket 41, the spring 8 rebounds, driving the round rod 7 and the semi-circular ring 5 to return to their original positions. At this time, the rotating block 120 on the outer circumference of the wire plug 12 is inserted vertically and along the through slot of the L-shaped groove 50 on the semi-circular ring 5. After being inserted into the through slot, the wire plug 12 is rotated so that the rotating block 120 is rotated into the narrow slot of the L-shaped groove 50 to complete the fixation.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
