Description

Technical Field

[0001] This application relates to the field of housing design technology for IO data acquisition devices, and more particularly to a housing for an IO data acquisition device for industrial control equipment. Background Technology

[0002] Industrial control equipment I / O data acquisition units are widely used in industrial automation. Their main function is to collect data from field devices and transmit the data to the control center via a communication interface. With the increasing level of industrial automation, the performance requirements for data acquisition units are also rising, especially in terms of enclosure design. A good enclosure not only protects the internal circuit boards from external environmental influences but also ensures the reliability and lifespan of the equipment. Furthermore, the enclosure design should also consider ease of installation and maintenance to adapt to the needs of different application scenarios.

[0003] Currently, to meet the above requirements, the housings of common industrial control equipment I / O data acquisition units on the market typically adopt the following design schemes: First, a metal housing is used, with the upper and lower housings fixed by screws, and the circuit board fixed internally by a plastic bracket; second, a plastic housing is used, with the upper and lower housings connected by a snap-fit ​​structure, and the circuit board fixed internally by positioning posts; third, a composite material housing is used, combining the advantages of metal and plastic, with the upper and lower housings fixed by adhesives or welding, and the circuit board fixed internally by rubber gaskets. These solutions, to a certain extent, solve the problems of housing protection and ease of installation.

[0004] However, existing housings for industrial control equipment I / O data acquisition units have some shortcomings. For example, while metal housings offer high strength, their weight hinders lightweight design; plastic housings, though lightweight, are prone to aging and deformation in harsh environments, affecting long-term stability; composite material housings, while combining the advantages of metal and plastic, are expensive and have complex assembly processes. Furthermore, existing housing designs often lack effective circuit board securing and battery locking mechanisms, leading to loosening during transportation and use, affecting normal equipment operation. Therefore, an improved housing design for industrial control equipment I / O data acquisition units is needed, which can improve equipment stability and reliability while ensuring protection. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a housing for an industrial control equipment IO data acquisition device that can improve the stability and reliability of the device while ensuring protection.

[0006] This application provides a housing for an industrial control equipment I / O data acquisition device, which adopts the following solution:

[0007] A housing for an industrial control equipment I / O data acquisition device includes: an upper housing with recessed holes at both ends and a first slot and a second slot on one side for exposing connectors; a lower housing that is fitted to the upper housing to form a mating space for accommodating a circuit board assembly, and having fixing holes at both ends corresponding to the recessed holes for fixing members to pass through sequentially to fix the upper housing and the lower housing; wherein two openings are provided on the side of the upper housing away from the lower housing, and engaging members protruding into the mating space are provided through the two openings for engaging a battery on the circuit board; wherein multiple limiting members are provided inside the upper housing and the lower housing for limiting the circuit board.

[0008] By adopting the above technical solution, the recessed holes at both ends of the upper housing and the corresponding fixing holes of the lower housing allow the outer shell to be stably installed on the equipment, improving the overall stability of the equipment. The first and second slots on one side of the upper housing allow the connectors to be easily exposed, facilitating connection to external equipment and improving operational convenience. The two openings on the side of the lower housing away from the upper housing and the locking components inside them effectively fix the battery on the circuit board, preventing the battery from falling off due to vibration or movement, thus enhancing the reliability and safety of the equipment. The multiple limiting components inside the upper and lower housings ensure that the circuit board will not shift during installation, guaranteeing the stability and contact reliability of the circuit board.

[0009] Optionally, the engaging component is provided with an engaging groove for engaging the battery.

[0010] By adopting the above technical solution, the locking component is provided with a locking groove for locking the battery, which can more stably fix the battery and prevent the battery from loosening due to external vibration or impact, thereby improving the reliability of the battery connection and ensuring the normal operation of the equipment.

[0011] Optionally, the engaging element is made of an elastic material.

[0012] By adopting the above technical solution, the locking component made of elastic material can effectively ensure the stability and reliability of the battery during installation, while facilitating battery replacement and maintenance. Specifically, the elastic material locking component can deform to a certain extent when the battery is inserted, thereby tightly fitting the battery surface and preventing the battery from loosening or falling off due to vibration or impact during use.

[0013] Optionally, multiple text markings are provided on the upper housing, located next to the first slot and the second slot, respectively.

[0014] By adopting the above technical solution, multiple text labels are set on the upper shell of the industrial control equipment IO data acquisition device, located next to the first and second slots respectively, which can facilitate users to quickly identify and operate the corresponding connectors, improving the ease of use and accuracy.

[0015] Optionally, the lower housing has a label groove for attaching labels on the side away from the upper housing, and the two openings are located in the label groove.

[0016] By adopting the above technical solution, a label groove is provided on the side of the lower shell away from the upper shell for label attachment. This allows labels to be easily attached to this position, avoiding problems such as label detachment or displacement, and improving the reliability and aesthetics of the labels. At the same time, the two openings are located in the label groove, ensuring the functionality of the openings without affecting the overall layout of the labels, thus enhancing the overall design of the product.

[0017] Optionally, the upper housing is provided with a through hole, which is a hexagonal hole for inserting a network port plug.

[0018] By adopting the above technical solution, and by setting a through hole on the upper shell, and setting the through hole as a hexagonal hole, it can facilitate the insertion of the network port plug-in, while also playing a limiting role to prevent the plug-in from loosening or falling off, thereby improving the connection strength and thus improving the working stability of the entire data acquisition device.

[0019] Optionally, the through hole is located between the first slot and the second slot.

[0020] By adopting the above technical solution, the through hole is positioned between the first and second slots, allowing the network port plug to be more rationally arranged inside the housing, improving space utilization and structural compactness. At the same time, this layout facilitates user operation and maintenance, enhancing both ease of use and aesthetics.

[0021] Optionally, the fastener is a threaded nail.

[0022] By adopting the above technical solution, using threaded nails as fasteners can effectively improve the structural stability of the housing of the industrial control equipment IO data acquisition unit, ensuring that it will not loosen or fall off during installation, thereby guaranteeing the normal operation and reliability of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The upper and lower housings, through the cooperation of grooves and fixing holes, achieve a stable mating structure, effectively preventing external environmental damage to the internal circuit board components and improving the protection and reliability of the equipment;

[0025] 2. The locking components protrude from both sides of the lower housing and have locking grooves, which can firmly fix the battery on the circuit board, prevent the battery from loosening during transportation and use, and ensure the stable operation of the equipment;

[0026] 3. Multiple limiting components can accurately position and fix the circuit board, preventing it from shaking inside the housing, thus further improving the reliability and service life of the equipment. Attached Figure Description

[0032] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0033] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] See Figure 1 and Figure 2 The present application discloses an industrial control equipment IO data acquisition device housing, which includes an upper housing 10 and a lower housing 20, which are fitted together to form a mating space 21 for accommodating circuit board assemblies to realize data acquisition function.

[0036] Among them, groove holes 11 are provided at both ends of the upper housing 10. Figure 1 As shown in the figure, a first slot 12 and a second slot 13 are provided on one side to expose the plug-in component installed in the mating space 21. The lower housing 20 has fixing holes 22 at both ends corresponding to the groove hole 11. The fixing component 30 passes through the groove hole 11 and the fixing hole 22 in sequence, so that the mating assembly of the upper housing 10 and the lower housing 20 can be realized.

[0037] Specifically, multiple text markings 14 are provided on the upper housing 10, located next to the first slot 12 and the second slot 13, respectively, to indicate the function and position of the connector. The text markings 14 can be made by laser engraving or screen printing to ensure they are clearly visible and not easily detached.

[0038] See Figure 2 The text label 14 next to the first slot 12 is ETP, which is the ETP communication interface. The text label 14 next to the second slot 13 includes X3, X3COM, X2, X2COM, X1, X1COM, GIN, YIN, etc., which correspond to the various interfaces of the connector, and will not be described in detail here.

[0039] In this embodiment, the fastener is a threaded nail, which can be used to assemble and fix the upper housing 10 and the lower housing 20 by screwing. This effectively improves the structural stability of the housing of the industrial control equipment IO data acquisition unit, ensuring that it will not loosen or fall off during installation, thereby guaranteeing the normal operation and reliability of the equipment.

[0040] In this embodiment, the circuit board assembly installed in the mating space 21 may include a circuit board, various functional connectors and a battery. Each functional connector and the battery are electrically connected to the circuit board. The connector holes of each functional connector are exposed from the first slot 12 and the second slot 13 respectively, and their functions are not limited here.

[0041] Further, see Figure 2 and Figure 3 Two openings 16 are provided on the side of the upper housing 10 away from the lower housing 20. A locking member 17 protruding into the mating space 21 is provided in the two openings 16 for locking the battery on the circuit board.

[0042] The locking component 17 is made of an elastic material such as silicone or TPU (thermoplastic polyurethane), providing good elasticity and durability. The locking component 17 has a locking groove 171 for securing the battery. During assembly, the elastic locking component 17 deforms slightly when the battery is inserted, and combined with the locking groove 171, it tightly fits the battery surface, further preventing the battery from loosening or falling off due to vibration or impact during use. Furthermore, when the battery needs to be removed, the locking component 17 quickly returns to its original shape, facilitating quick battery replacement for the user.

[0043] Furthermore, multiple limiting members 23 are provided inside the upper housing 10 and the lower housing 20 to facilitate the limiting of the circuit board and ensure that the circuit board will not shift during installation, thus ensuring the stability and contact reliability of the circuit board during use.

[0044] Further, see Figure 2 A label groove 24 is provided on the upper part of the lower housing 20, located on the side away from the upper housing 10. Two openings 16 are located in the label groove 24. When the label is attached to the label groove 24, it can cover the two openings 16, and the plane of the label is kept on the same plane as the surface of the lower housing 20. This not only avoids the problem of the label falling off or shifting, but also improves the reliability and aesthetics of the label.

[0045] Additionally, see Figure 3 A through hole 15 is provided on the upper shell 10, located between the first slot 12 and the second slot 13, so that the network port plug can be arranged more reasonably inside the shell, improving space utilization and structural compactness.

[0046] The through hole 15 can also be configured as a hexagonal hole ( Figure 3 The center part is a circle (please ignore it). It is used for inserting network port plugs. When the network port plugs are inserted, it acts as a limit to prevent the plugs from becoming loose or falling off, thereby improving the overall stability of the data acquisition device.

[0047] In summary, the industrial control equipment IO data acquisition device housing disclosed in this application has an upper housing 10 and a lower housing 20 that form a stable mating structure through the cooperation of the groove hole 11 and the fixing hole 22. This effectively isolates the external environment from the internal circuit board, improving the protection and reliability of the device. The locking member 17 provided on the lower housing 20 can firmly fix the battery on the circuit board, preventing the battery from loosening during transportation and use, and ensuring the stable operation of the device. The multiple limiting members 23 provided inside can accurately position and fix the circuit board, preventing the circuit board from shaking inside the housing, thus improving the overall reliability and service life of the device.
