Description

Technical Field

[0001] This utility model relates to the field of industrial control equipment technology, and in particular to an anti-misinsertion component and industrial control device. Background Technology

[0002] In industrial control systems, modular products are widely used. Multiple modules typically share the same backplane base, and different modules need to be installed in corresponding mounting slots on the backplane base. Anti-misfit (i.e., preventing incorrect insertion) is a crucial design goal to ensure safe system operation and prevent damage caused by misoperation. Therefore, anti-misfit structures are widely adopted. Existing anti-misfit structures generally use multiple coding elements of different shapes and sizes for pairing and identification. Since two or more different coding elements need to be installed separately on the module and the base, mixing can easily occur during assembly, reducing the product's versatility and interchangeability.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of the present utility model.

[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0050] Furthermore, in the embodiments of this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of the embodiments of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0052] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by the embodiments of this utility model.

[0053] In industrial control products, different types of functional modules (i.e., I / O modules) are often assembled using a single backplane base. A complete system typically includes various modules such as digital, analog, and temperature measurement modules. Each module has a different function and requires a different insertion position in the backplane base slot. Therefore, a pairing relationship is needed between the functional modules and the backplane base to prevent incorrect insertion. Currently, coding pairs are usually introduced as an intermediary bridge between the module and the backplane base. The functional module can only be inserted into the backplane base slot when the code of the functional module and the backplane base are the same; otherwise, it cannot, thus preventing incorrect insertion.

[0054] Currently, coding pairs mainly utilize the key-lock principle and are typically composed of two or more plastic components with different structures. The two different coding components need to be mounted separately on the functional module and the backplate base. With a large number of functional modules, even more coding components are required. This large number of components makes it easy for materials to mix during assembly, reducing the product's versatility and interchangeability.

[0055] In view of this, the present invention provides a material unification anti-mixing component and industrial control device, which aims to solve the above problems.

[0056] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0057] like Figures 1 to 3 , Figures 11 to 13 As shown in the figure, this utility model embodiment proposes an anti-misfit assembly for assembling a first component to a second component. The anti-misfit assembly includes an encoding pair, which includes two encoding elements 100 with identical structures. One encoding element 100 is fixed to the first component, and the other encoding element 100 is fixed to the second component. Each encoding element 100 includes an encoding body 110, a first connecting portion 120, and a second connecting portion 130. The first connecting portion 120 and the second connecting portion 130 are disposed on the encoding body 110. The first connecting portion 120 of one encoding element 100 is connected to the second connecting portion 130 of the other encoding element 100.

[0058] Specifically, the anti-misfit assembly includes an encoding pair, which comprises two encoding elements 100 with identical structures. The first component and the second component are respectively connected to the encoding elements 100. The encoding elements 100 on the first component and the second component, having the same bit code, form an encoding pair. At this time, the first connecting portion 120 of the encoding element 100 on the first component and the second connecting portion 130 on the second component are connected, fixing the two encoding elements 100 and realizing the assembly between the first component and the second component. It can be understood that the encoding elements 100 are installed on the first component according to the required bit code, and the encoding elements 100 are installed on the second component according to the required bit code. Since the encoding elements 100 have identical structures, when installing the encoding elements 100, either encoding element 100 can be selected to be installed on the first component or the second component; only the bit code of the encoding element 100 needs to be adjusted as needed. It can be understood that different bit codes represent different orientations of the first connecting portion 120 and the second connecting portion 130 on the encoding element 100.

[0059] Optionally, refer to Figure 2 , Figure 6 as well as Figure 7The first and second components are further provided with character identifiers 210, and each of the encoding elements 100 also includes an indicator identifier 150. At least one of the encoding body 110, the first connecting part 120, and the second connecting part 130 is provided with the indicator identifier 150. When the character identifier 210 pointed to by the indicator identifier 150 of one encoding element 100 is the same as the character identifier 210 pointed to by the indicator identifier 150 of another encoding element 100, the two encoding elements 100 can be connected and fixed. It can be understood that the character identifier 210 pointed to by the indicator identifier 150 is the bit code of the encoding element 100. In this way, it can be ensured that the first component is installed in the predetermined position of the second component as needed, preventing mis-insertion. Moreover, the operator can directly observe the character identifier 210 pointed to by the indicator identifier 150 to clearly see the bit code of the encoding element 100 at this time, and then connect the encoding elements 100 with the same bit code together to realize the assembly of the first component on the second component, improving the operator's operational convenience and assembly efficiency.

[0060] In this embodiment, by using two identical coding elements 100 as a coding pair, the number of parts and molds is reduced, material standardization is achieved, the production process is simplified, and manufacturing costs are lowered. Furthermore, because the coding elements 100 have identical structures, they can be used interchangeably during initial assembly. Operators do not need to identify them and can choose either coding element 100 to install on the first or second component, avoiding mixing due to structural differences. This facilitates standardized production and on-site assembly, effectively improving product versatility and maintenance convenience. Additionally, if a single coding element 100 is damaged, it can be directly replaced with another coding element 100 without needing to be replaced in pairs, reducing usage and maintenance costs.

[0061] In one embodiment of this utility model, the encoding body 110 has opposing first and second surfaces. The first connecting portion 120 is configured as a through hole penetrating the first and second surfaces, and the second connecting portion 130 is configured as an encoding post protruding from the first surface. The encoding post of one encoding element and the through hole of another encoding element are inserted into each other. It can be understood that when assembling the first component onto the second component, based on the bit code of the encoding element 100 on the first component, an encoding element 100 on the second component with the same bit code is selected, and then the encoding post is inserted into the through hole. That is, the assembly of the first component onto the second component can be achieved through the insertion of the encoding post and the through hole, making the operation simpler and more convenient. Specifically, the encoding post of the encoding element 100 on the first component and the through hole of the encoding element 100 on the second component are inserted into each other, and the encoding post of the encoding element 100 on the second component and the through hole of the encoding element 100 on the first component are also inserted into each other, thereby achieving the anti-misinsertion function.

[0062] Optionally, the cross-sectional shape of the coding post and the shape of the through hole are adapted and symmetrically arranged about the center of the coding body 110. Only when the alignment is accurate can the insertion be completed, further preventing mis-insertion or incorrect insertion. In one embodiment, the coding post can be a cylinder or a prism. In another embodiment, the coding post and the through hole are interference-fitted, thus preventing the coding post and the through hole from separating.

[0063] In one embodiment of this utility model, the through hole and the coding post are arranged diagonally, which can make full use of the space of the coding body 110, achieve a compact arrangement of the coding post and the through hole, make the coding body 110 more compact, and reduce the overall volume of the coding element 100.

[0064] In one embodiment of this utility model, reference is made to Figures 3 to 5 The encoding element 100 further includes a plug-in fixing structure 140, which includes a first fixing part 141 and a second fixing part 142. An extension part 111 is protruding from the second surface. The first fixing part 141 is provided on one of the peripheral surface of the encoding post and the extension part 111, and the second fixing part 142 is provided on the other of the peripheral surface of the encoding post and the extension part 111.

[0065] When two encoding elements 100 are plugged in, the encoding post of one encoding element 100 passes through the through hole of the other encoding element 100, and the first fixing part 141 of one encoding element 100 cooperates with the second fixing part 142 of the other encoding element 100 to lock.

[0066] Specifically, the encoding element 100 also includes a plug-in fixing structure 140. This plug-in fixing structure 140 further fixes the encoding post and the through hole, improving the reliability of the plug-in connection. Specifically, the plug-in fixing structure 140 includes a first fixing part 141 and a second fixing part 142. The first fixing part 141 is disposed on the circumferential surface of the encoding post, and the second fixing part 142 is disposed on the extension 111; alternatively, the first fixing part 141 is disposed on the extension 111, and the second fixing part 142 is disposed on the circumferential surface of the encoding post. The first fixing part 141 and the second fixing part 142 can be a protrusion structure or a plug-in structure, which is not limited here. Optionally, the encoding post and the extension 111 are disposed on opposite sides of the encoding body 110 and protrude in opposite directions. The encoding post and the extension are staggered along the axial direction of the encoding body 110, which facilitates the plug-in of the two encoding elements 100.

[0067] In one embodiment of this utility model, the first fixing part 141 is configured as a slot on the periphery of the coding post, and the second fixing part 142 is configured as a locking head on the extension part 111. Through the mating structure of the slot and the locking head, the anti-misinsertion function is achieved, while also enhancing the stability and firmness of the connection, reducing the problem of loosening caused by vibration or external force. Furthermore, the locking structure of the locking head and the slot provides better locking feedback, enhancing the user's operational experience.

[0068] In one embodiment of this utility model, the slot extends axially along the coding post. It can be understood that the extension direction of the slot is parallel to the direction in which the coding post is inserted into the through hole. Thus, when the coding post is inserted into the through hole and the card head is engaged in the slot, the card head can slide within the slot under the action of external force, providing tolerance and error correction function; and / or, two slots are provided at intervals along the circumference of the coding post, and each slot corresponds to a card head. Thus, the coding post can be fixed at different positions. Fixing at multiple positions can further improve the reliability of the connection between the coding post and the through hole.

[0069] In one embodiment of this utility model, reference is made to Figures 2 to 8 , Figures 11 to 13 The encoding element 100 further includes a snap-fit ​​structure 160. The snap-fit ​​structure and the second connecting portion 130 are located on opposite sides of the encoding body 110. The first component and the second component are respectively provided with mounting grooves 221. The snap-fit ​​structure 160 passes through the mounting groove 221 and snaps onto the side surface of the mounting groove 221 facing away from the second connecting portion 130. The encoding body 110 abuts against the side surface of the mounting groove 221 facing the encoding post. Thus, the encoding body 110 and the snap-fit ​​structure 160 abut against opposite sides of the mounting groove 221, facilitating the fixing of the encoding element 100 to the first component or the second component and restricting the vertical movement of the encoding element 100. Specifically, the snap-fit ​​structure 160 is elastic; it can deform inward to pass through the mounting groove 221 and then expand outward to return to its original shape. The snap-fit ​​structure 160 abuts against the side surface of the mounting groove 221 facing away from the encoding post, thereby fixing the encoding element 100 to the first component or the second component. Optionally, multiple snap-fit ​​structures 160 are provided to further improve the reliability of the fixation.

[0070] In one embodiment of this utility model, reference is made to Figure 7The first and second components are further provided with limiting grooves 222 communicating with the mounting groove 221. The inner diameter of the limiting groove 222 is larger than the inner diameter of the mounting groove 221 to form a stepped surface at the connection between the limiting groove 222 and the mounting groove 221. The encoding body 110 is at least partially embedded in the limiting groove 222 and abuts against the stepped surface. On the one hand, the limiting groove 222 can limit the encoding body 110, preventing the encoding body 110 from sliding relative to the first or second component when subjected to vibration or other external forces. On the other hand, it can reduce the height of the encoding body 110 protruding from the first or second component, reducing the space occupied.

[0071] In one embodiment of this utility model, reference is made to Figure 2 , Figure 3 , Figure 8 The snap-fit ​​structure 160 is rotatably disposed in the mounting groove 221 to adjust the character identifier 210 pointed to by the indicator 150. One of the snap-fit ​​structure 160 and the mounting groove 221 is provided with a feedback recess 231, and the other of the snap-fit ​​structure 160 and the mounting groove 221 is provided with a feedback protrusion 232. Multiple feedback recesses 231 are provided along the rotation direction of the snap-fit ​​structure 160 and are correspondingly arranged with the character identifier 210. When the snap-fit ​​structure 160 rotates, the feedback protrusion 232 rotates between two adjacent feedback recesses 231.

[0072] Specifically, through the rotatable latching structure 160, the indicator 150 can rotate synchronously with the latching structure 160. Users can flexibly select and confirm the currently set character indicator 210 according to actual needs, improving operational convenience and flexibility, and facilitating later on-site maintenance. When the feedback protrusion 232 rotates between two adjacent feedback recesses 231, it can generate obvious tactile and audible feedback, allowing users to accurately perceive the encoding switching status, improving the operating experience and reliability. Moreover, when the feedback protrusion 232 rotates from one feedback recess 231 to another adjacent feedback recess 231, it needs to overcome damping force, thus preventing the latching structure 160 from rotating arbitrarily without human intervention.

[0073] In one embodiment of this utility model, reference is made to Figure 8 and Figure 10At least one of the first and second components has a mounting groove 221 with a rotating limiting rib 241 on the side surface facing away from the coding body 110. The rotating limiting ribs 241 are arranged in multiple intervals along the circumference of the mounting groove 221, and the number is equal to the number of the character identifiers 210. A character identifier 210 is provided between each two adjacent rotating limiting ribs 241. The two adjacent rotating limiting ribs 241 are used to abut against the buckle structure 160 to limit the rotation of the buckle structure 160.

[0074] It is understood that in this embodiment, the two adjacent rotation limiting ribs 241 can restrict the rotation of the snap-fit ​​structure 160, that is, the snap-fit ​​structure 160 is fixed between the two adjacent rotation limiting ribs 241 and cannot rotate. In this way, the position code can be fixed, and the accuracy of assembling the first component into the second component can be improved.

[0075] In another embodiment of this utility model, referring to Figures 4 to 6 One of the encoding body 110 and the mounting groove 221 is provided with a limiting protrusion 242, and the other of the encoding body 110 and the mounting groove 221 is provided with a limiting recess 243. The limiting protrusion 242 is engaged with the corresponding limiting recess 243. In this embodiment, the cooperation between the limiting recess 243 and the limiting protrusion 242 can also prevent the buckling structure 160 from rotating. Optionally, each character identifier 210 is provided with one limiting protrusion 242, and the limiting protrusion 242 and the limiting recess 243 are provided in a one-to-one correspondence. Of course, in other embodiments, there are multiple limiting recesses 243, and each character identifier 210 is provided with one limiting recess 243, and at least one limiting protrusion 242 is provided. In another embodiment, there is at least one limiting recess 243, and multiple limiting protrusions 242, and each character identifier 210 is provided with one limiting protrusion 242.

[0076] In one embodiment of this utility model, reference is made to Figure 6 , Figure 7 as well as Figure 9 The mounting slot 221 has a pry hole structure 250 on the side facing the coding body 110 for inserting a pry tool.

[0077] Understandably, when the snap-fit ​​structure 160 is fixed and cannot rotate, a prying structure 250 can be provided. Prying tools such as screwdrivers can use the prying structure 250 to pry the coding body 110 out of the mounting slot 221, detaching the coding element 100 from the first or second component. After setting other bit codes, the coding element 100 can then be reinstalled onto the first or second component. In other words, the prying structure 250 allows the coding element 100 to be detached from the first or second component, facilitating the readjustment of the bit codes of the coding element 100.

[0078] In one embodiment of this utility model, the prying structure 250 includes a prying groove, which is located on one side of the mounting groove 221 and communicates with the mounting groove 221. It is understood that the prying groove is located on the groove wall of the mounting groove 221 and extends away from the mounting groove 221. A prying tool can be inserted through the prying groove to the surface of the coding body 110 facing away from the coding post, and then pry the coding body 110 out of the mounting groove 221 until the coding element 100 detaches from the first component or the second component. Optionally, the prying groove can be rectangular, circular, or other irregularly shaped, and is not limited herein.

[0079] To achieve the above objectives, refer to Figures 1 to 20 This utility model embodiment proposes an industrial control device, which includes a functional module 310, a base 320, and the aforementioned anti-misfit insertion component. One of the functional module 310 and the base 320 forms the first component, and the other of the functional module 310 and the base 320 forms the second component. Specifically, the specific structure of the anti-misfit insertion component refers to the above embodiment. Since this industrial control device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0080] Specifically, industrial control devices primarily perform data acquisition, process control, status monitoring, and adjustment of production lines or mechanical equipment to improve production efficiency, ensure product quality, enhance safety, and reduce manual intervention. Industrial control devices typically include: a control unit (such as a CPU module) responsible for running the control program; input / output modules (I / O modules), i.e., functional modules 310, used to connect external sensors and actuators; a communication module supporting various industrial bus protocols (such as Modbus, Profibus, EtherCAT, etc.); a power supply module providing a stable power supply to the system; terminal blocks for electrical connections; and a control board for electrical connections and signal transmission.

[0081] In this embodiment, there are multiple functional modules 310, and all of the multiple functional modules 310 are mounted on the base 320, that is, multiple functional modules 310 share a back plate base 320.

[0082] In one embodiment of this utility model, each functional module 310 is provided with two anti-misfit components. It is understood that when each functional module 310 is installed onto the base 320, misfitting is prevented by the two anti-misfit components, which further improves the anti-misfitting effect.

[0083] Optionally, refer to Figures 12 to 20When the functional module 310 and base 320 are shipped from the factory, a coding pair consisting of two identical coding elements 100 can be pre-installed on the functional module 310, while the base 320 is initially not equipped with coding elements 100. That is, the first coding element 100 in a coding pair is fixed to the functional module 310 by a snap-fit ​​structure 160. The coding post of the second coding element 100 is inserted into the through hole of the first coding element 100 and extends into the mounting groove. The snap-fit ​​head of the second coding element 100 is then snapped into the slot of the first coding element 100, thus achieving factory-fixed fixation of the two coding elements 100 in a coding pair. This facilitates transportation. During on-site assembly, the pairing position of the functional module 310 and base 320 can be selected according to actual usage requirements. The snap-fit ​​structure 160 of the second coding element 100 passes through the mounting groove 221 of the base 320 and snaps onto the side of the mounting groove 221 of the base 320 facing away from the functional module 310. When the functional module 310 is pulled out, the two coding elements 100 will separate because the locking force of the two coding elements 100 fixed by the plug-in fixing structure 140 is less than the locking force of the coding elements 100 fixed by the snap-fit ​​structure 160. The first coding element 100 remains in the functional module 310 and the second coding element 100 remains in the base 320.

[0084] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model embodiments. Any equivalent structural transformations made under the technical concept of the present utility model using the description and drawings of the present utility model embodiments, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model embodiments.
