[0002] A switch signal collector is a device used to detect and collect the status of switch signals. It is usually used to monitor the open and closed status of the switch and convert it into a digital signal for further processing or control.

[0003] The application scenarios of switch signal collectors are diverse. For example, in industrial automation, switch signal collectors can be used to monitor the switch status on the production line to trigger corresponding operations or alarms; in building automation, switch signal collectors can be used to monitor the status of switching devices, such as lights and air conditioners; in laboratories or scientific research, switch signal collectors can be used to record and analyze parameters such as the time and frequency of switch events.

[0004] Among the switch signal acquisition products on the market, there are products that can collect four-way switch quantities and have four-way relay output functions. These products have many interfaces, which are used to connect to the circuit wires to be detected to detect switch signals and other signals. When there is no detection, these interfaces will be exposed to the environment and affected by moisture in the air, causing the metal surface inside the interface to oxidize, which will increase resistance or change the conductive properties of the connection, and ultimately cause signal attenuation or distortion in signal transmission, resulting in the inability of the switch signal acquisition product to accurately collect switch quantity signals.

[0024] The utility model provides a switch signal collector protection structure. It is used to seal and dehumidify the interface 101 of the switch signal collector 100. The structure of the switch signal collector 100 can be found in Figures 1 to 3 The switch signal collector 100 has a plurality of interfaces 101 at the top and bottom, respectively, and these interfaces 101 are used for inserting power lines. Accordingly, the switch signal collector 100 has a plurality of structures for tightening in front, and the wires inserted into the interfaces 101 can be clamped by rotating the structures with tools. The switch signal collector 100 has a slide groove that cooperates with the slide rail at the back, and when the switch signal collector 100 is fastened on the slide rail, it can move on the slide rail. The above-mentioned switch signal collector 100 is a prior art and will not be introduced in detail here.

[0025] In the embodiment of the present utility model, Figures 1 to 4 As shown, the switch signal collector protection structure includes a carrier 1 and multiple sealing blocks 2, the multiple sealing blocks 2 are all installed on the same side of the carrier 1, the multiple sealing blocks 2 are arranged at intervals, the multiple sealing blocks 2 and the multiple interfaces 101 on the same side wall of the switch signal collector 100 are the same in number and correspond one to one, the sealing blocks 2 can be interference fit with the corresponding interfaces 101, and the structure located inside the interface 101 on the sealing block 2 is penetrated by a dehumidification port 221, a storage cavity 23 connected to the dehumidification port 221 is provided in the sealing block 2, and water-absorbing particles 3 are provided in each storage cavity 23, and the maximum diameter of the water-absorbing particles 3 is larger than the diameter setting of the dehumidification port 221.

[0026] The sealing block 2 is made of a deformable material so as to facilitate its deformation and filling the interface 101. In specific implementation, the sealing block 2 can be made of rubber, polyurethane, elastic plastic (such as polyethylene (PE), polypropylene (PP), etc.) or silicone.

[0027] The dehumidification port 221 is designed to be smaller than the water-absorbing particles 3 in order to prevent the water-absorbing particles 3 from falling out of the dehumidification port 221. Since the storage chamber 23 is connected to the environment inside the interface 101 through the dehumidification port 221, the water-absorbing particles 3 can effectively absorb the moisture in the internal environment of the interface 101, and further maintain the dryness of the interface 101. In specific implementation, the material of the water-absorbing particles 3 can be anhydrous copper sulfate, molecular sieve, calcium chloride, high hygroscopic fiber material (such as bamboo fiber, wood fiber, etc.), etc., which are not listed here one by one.

[0028] It can be understood that in the switch signal collector protection structure of the technical solution of the utility model, the sealing block 2 and the interface 101 are interference fit to prevent water vapor in the environment from entering the interior of the interface 101, and then, the water in the internal environment of the interface 101 is absorbed by the water-absorbing particles 3 inside the interface 101, thereby effectively maintaining the dryness of the interior of the interface 101, preventing the metal inside the interface 101 from getting damp and oxidized, which is beneficial to extending the service life of the switch signal collector 100.

[0029] In a specific implementation, the carrier 1 can be a flexible pad or a hard plate, as long as it can carry a plurality of sealing blocks 2, and its specific structure is not limited here.

[0030] The sealing block 2 includes a mounting portion 21 and a sealing portion 22 connected to each other. The mounting portion 21 is detachably mounted on the carrier 1. The sealing portion 22 is interference fit with the corresponding interface 101. The dehumidification port 221 is provided on the sealing portion 22. A portion of the storage chamber 23 is formed on the sealing portion 22. Another portion of the storage chamber 23 is formed on the mounting portion 21. The storage chamber 23 is also provided with a material exchange port 211 on the side of the mounting portion 21 facing the carrier 1. The water-absorbing particles 3 can enter and exit the storage chamber 23 through the material exchange port 211.

[0031] It is not difficult to understand that by designing the sealing block 2 to be detachable, the sealing block 2 can be easily replaced or maintained. After the water-absorbing particles 3 absorb water vapor, the user can remove the sealing block 2 from the carrier 1, pour out the water-saturated water-absorbing particles 3 through the material replacement port 211, and then re-introduce new water-absorbing particles 3 into the storage chamber 23, so as to facilitate the continuous use of the product.

[0032] In specific implementation, there are many ways of detachable connection between the mounting portion 21 and the carrier 1, such as both are provided with magnets, and the two are fixed together by the magnetic attraction between the magnets. In other embodiments, one of the mounting portion 21 and the carrier 1 is provided with a Velcro hook surface (not shown in the figure), and the other is provided with a Velcro velvet surface (not shown in the figure), and the Velcro hook surface is bonded to the Velcro velvet surface to fix the mounting portion 21 on the carrier 1.

[0033] The present application gives priority to the second embodiment, that is, the installation of the mounting part 21 is achieved by bonding the Velcro velvet surface to the Velcro velvet surface. It is not difficult to understand that the Velcro hook surface and the Velcro velvet surface have a certain flexibility and can be installed on different surfaces. It has strong adaptability and reduces the difficulty of implementation. In addition, the Velcro blanket can be used as a water-absorbing material to prevent moisture from entering the storage cavity 23. In this embodiment, the carrier 1 can be a blanket, so that the blanket itself can be used as the velvet surface of the Velcro, eliminating the step of installing the Velcro velvet surface.

[0034] The carrier 1 is provided with a Velcro velvet surface, and a mounting mark (not shown) is provided on the Velcro velvet surface. The mounting mark is provided in a circular ring shape, and the diameter of the mounting mark is the same as the diameter of the refueling port 211. By aligning the mounting mark with the refueling port 211 and placing the mounting portion 21 in the correct position, the mounting operation can be completed quickly and accurately, avoiding possible errors.

[0035] The presence of the installation mark can help the operator more easily find and correct any deviation or error during the installation process. If the installation portion 21 is not correctly aligned with the installation mark, it can be adjusted in time to ensure the quality and accuracy of the installation.

[0036] In specific implementation, in some embodiments, color or marking can be sprayed on the surface of the carrier 1 to form an installation mark. This method can use conventional spray paint or marking ink, and is generally suitable for flat surfaces. In other embodiments, the installation mark can be engraved on the surface of the carrier 1 by laser or mechanical engraving. In some other embodiments, a sticker with a mark printed on it can be affixed to the surface of the carrier 1 to form an installation mark.

[0037] Specifically, the material of the water-absorbing particles 3 is anhydrous copper sulfate. It is not difficult to understand that when anhydrous copper sulfate absorbs water, a hydration reaction will occur to generate a soluble crystal (copper sulfate pentahydrate (CuSO4·5H2O)), also known as alum blue. In this process, its color will change significantly, and its color will gradually change from colorless to blue. The user can judge whether the water-absorbing particles 3 are saturated with water by observing the color of the water-absorbing particles 3, and then decide whether to replace the water-absorbing particles 3.

[0038] At least part of the cavity wall of the storage cavity 23 is transparent so that the user can observe the water-absorbing particles 3 in the storage cavity 23. This design allows the user to directly observe the water-absorbing particles 3 in the storage cavity 23 without removing the sealing block 2 from the carrier 1 and then observing the extension of the water-absorbing particles 3, which provides convenience for the user.

[0039] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
