Description

Technical Field

[0001] The utility model relates to the technical field of electrical assembly, and particularly relates to a wire threading and sealing device. Background Art

[0002] At present, the stack chamber and the electrical control room of the AEM (anion exchange membrane) electrolyzer container are two independent spaces, and a sealed isolation is required between the two chambers. Since the two chambers need to be connected by cables, generally, a PG head is installed by opening a hole in the partition wall between the two chambers, or the diameter of the wire threading hole is set not to be greater than the diameter of the cable, so as to realize the sealing of the two chambers after wire threading. The PG head mainly realizes the sealing by rotating and locking the thread to compress the wire threading space. However, when the number of cables is relatively large, a large number of PG heads need to be installed, which has a high cost, occupies a large space, and is difficult to layout; when installing the cable by setting the diameter of the wire threading hole not to be greater than the diameter of the cable, it will be relatively difficult, and the insulating layer of the cable will be damaged due to friction during installation. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a wire threading and sealing device to at least solve the problem of difficult installation of the existing wire threading and sealing device.

[0004] According to one aspect of the utility model, a wire threading and sealing device is provided, including:

[0005] A substrate, on which a first wire threading hole is provided;

[0006] A pressing plate, fixedly connected to the substrate, and a second wire threading hole is provided on the pressing plate;

[0007] A sealing and mounting member, embedded between the substrate and the pressing plate, with a protruding portion provided on the sealing and mounting member. A through hole, the first wire threading hole and the second wire threading hole are arranged along the same straight line, and the protruding portion is hermetically connected to the first wire threading hole.

[0008] Furthermore, each of the first wire threading hole, the second wire threading hole and the through hole includes at least one, and the first wire threading hole, the second wire threading hole and the through hole are arranged in one-to-one correspondence.

[0009] Furthermore, the through hole is a tapered hole, and the cross-sectional area of the tapered hole gradually decreases along the direction from the pressing plate to the substrate.

[0010] Furthermore, the protruding portion includes a tapered column, and the cross-sectional area of the tapered column gradually decreases along the direction from the pressing plate to the substrate.

[0011] Further, the substrate has a first protruding portion protruding from the outer peripheral side of the pressing plate, and a connecting portion for fixing the wire threading sealing device to a predetermined structure is provided on the first protruding portion.

[0012] Further, the connecting portion includes a plurality of connecting holes, and the plurality of connecting holes are arranged at intervals along the outer periphery of the substrate.

[0013] Further, the pressing plate and the substrate are fixedly connected by fasteners, and the fasteners include at least one of connecting bolts, connecting screws or connecting buckles.

[0014] Further, the sealing mounting member is arranged in a sheet-like structure, and there is a predetermined distance between the outer edge of the sheet-like structure and the outer edges of both the pressing plate and the substrate, and the fasteners are located on the outer peripheral side of the sheet-like structure.

[0015] Further, the aperture of the first wire threading hole is larger than the outer diameter of the cable, and the aperture of the second wire threading hole is larger than the outer diameter of the cable.

[0016] Further, the sealing mounting member includes a rubber plate, and / or the substrate includes an insulating plate, and / or the pressing plate includes an insulating plate.

[0017] In the present utility model, by providing a sealing mounting member and embedding it between the substrate and the pressing plate, the wire threading process of the cable becomes simpler and more direct. There is no need to install PG heads individually on each cable or precisely control the aperture of the wire threading holes, thereby reducing the installation steps and complexity. Compared with the traditional method that uses a large number of PG heads, the device reduces the usage amount of components. Especially when the number of cables is large, the cost-saving effect is significant. In addition, it reduces the material waste and labor costs during the installation process. Since there is no need to install separate seals on each cable, the entire wire threading sealing device occupies less space, making the space layout inside the container more flexible and efficient. This is particularly important for the equipment layout in a limited space. The protruding portion design on the sealing mounting member enables the cable to form a tight sealing connection with the first wire threading hole when passing through, effectively preventing the leakage of gas or liquid and improving the sealing performance of the entire system. Since the cable passes through the pre-designed through holes, the risk of damaging the cable insulation layer due to friction during the installation process is avoided, thereby extending the service life of the cable. When it is necessary to replace or repair the cable, it can be easily completed by loosening the pressing plate without damaging the entire sealing structure, improving the convenience and efficiency of maintenance.

[0026] See Figures 1 to 2As shown, according to an embodiment of the present application, a wire threading and sealing device is provided, including a substrate 10, a pressing plate 20 and a sealing mounting member 30. Among them, a first wire threading hole 11 is provided on the substrate 10. The pressing plate 20 is fixedly connected to the substrate 10, and a second wire threading hole 21 is provided on the pressing plate 20. The sealing mounting member 30 is embedded between the substrate 10 and the pressing plate 20. A protruding portion 31 is provided on the sealing mounting member 30. A through hole 311 is provided on the protruding portion 31. The first wire threading hole 11, the second wire threading hole 21 and the through hole 311 extend along the same straight line, and the protruding portion 31 is sealingly connected to the first wire threading hole 11.

[0027] In this embodiment, the protruding portion 31 of the sealing mounting member 30 is sealingly connected to the first wire threading hole 11 on the substrate 10, forming a tight sealing structure, which can achieve the sealing between the through hole 311 of the protruding portion 31 of the sealing mounting member 30 and the cable 40, effectively preventing the communication between different compartments through the cable 40 connection, and avoiding the gas in one compartment from entering another compartment through the cable 40 opening in the partition wall between the compartments, ensuring the safety of the electrical components in the internal environment of the electrical equipment. When the cable 40 passes through the first wire threading hole 11 on the substrate 10, the through hole 311 of the protruding portion 31 of the sealing mounting member 30, and the second wire threading hole 21 on the pressing plate 20 in sequence, since the sealing mounting member 30 is embedded between the substrate 10 and the pressing plate 20, the sealing mounting member 30 will be pressed by the substrate 10 and the pressing plate 20 and sealingly connected to the first wire threading hole 11.

[0028] Furthermore, the first wire threading hole 11, the second wire threading hole 21 and the through hole 311 each include at least one, and the first wire threading hole 11, the second wire threading hole 21 and the through hole 311 are arranged in one-to-one correspondence. The design of multiple sets of corresponding first wire threading holes 11, second wire threading holes 21 and through holes 311 ensures that the cable 40 can be accurately aligned when passing through each hole, avoiding problems such as cable twisting, abrasion or poor connection caused by misalignment or deviation. By reasonably arranging the positions and numbers of multiple wire threading holes and through holes 311, the wiring layout of the device can be further optimized, which helps to reduce cable crossing and interference, and improve the neatness and aesthetics inside the device.

[0029] Furthermore, the through hole 311 is a tapered hole, and the cross-sectional area of the tapered hole gradually decreases along the direction from the pressing plate 20 to the substrate 10. The design of the tapered hole enables the cable to form a tighter fit with the hole wall when passing through, which can solve the problem of facilitating wire insertion, reduce the leakage risk caused by excessive gaps, and contribute to enhancing the sealing effect. As the cross-sectional area gradually decreases, the pressure on the cable in the tapered hole gradually increases, further enhancing the reliability of the seal. This tapering effect helps to ensure that the cable can still maintain a stable sealed state when subjected to external forces. The design of the tapered hole provides a gradually tightening fixing space for the cable, which helps to enhance the stability of the cable in the hole. The design of the tapered hole can also reduce the friction and extrusion between the insulating layer and the hole wall, thereby protecting the integrity of the insulating layer and ensuring the electrical performance and safety of the cable 40.

[0030] Furthermore, the protruding portion 31 includes a tapered column, and the cross-sectional area of the tapered column gradually decreases along the direction from the pressing plate 20 to the substrate 10. The design of the tapered column enables a tighter fit to be formed between the sealing and mounting member 30 and the first wire passing hole 11, facilitating the insertion of the protruding portion into the first wire passing hole. As the cross-sectional area of the tapered column gradually decreases, the contact pressure between it and the inner wall of the first wire passing hole 11 gradually increases, thereby enhancing the sealing effect and ensuring the cleanliness of the internal environment of the electrical equipment and the safety of the electrical components. The design of the tapered column has a certain self-adaptability and can adapt to cables of different diameters. When the cable passes through, the tapered column will automatically adjust the sealing state according to the diameter of the cable to ensure that the sealing effect is not affected by changes in the cable diameter.

[0031] Furthermore, the substrate 10 has a first protruding portion 31 protruding from the outer peripheral side of the pressing plate 20, and a connecting portion for fixing the wire passing and sealing device to a predetermined structure is provided on the first protruding portion 31. The first protruding portion 31 and the connecting portion thereon can provide a fixing point, enabling it to be more firmly mounted on the predetermined structure. The connection helps to reduce the risk of loosening or falling off caused by vibration, shock or external forces, ensuring the stability and reliability of the device during long-term use. Since the connecting portion is provided on the first protruding portion 31 protruding from the outer peripheral side of the pressing plate 20, it is convenient for wiring the device, reducing the crossing and interference of the cables, and improving the cleanliness and safety of the equipment.

[0032] Furthermore, the connecting part includes a plurality of connecting holes 12, which are arranged at intervals along the outer periphery of the substrate 10. By providing the plurality of connecting holes 12, multi-point fixation of the wire threading and sealing device on a predetermined structure can be achieved. The multi-point fixation method is more stable than single-point or few-point fixation, can effectively disperse the fixing force, and reduce the risk of loosening or damage caused by excessive stress at a single point. The connecting holes 12 are arranged at intervals along the outer periphery of the substrate 10, so that the fixing force can be evenly distributed over the entire device, avoiding deformation or damage problems caused by uneven stress, and contributing to improving the stability and durability of the device.

[0033] Furthermore, the pressing plate 20 and the substrate 10 are fixedly connected through a fastener 210, and the fastener 210 includes at least one of a connecting bolt, a connecting screw, or a connecting buckle. By providing the fastener 210 between the pressing plate 20 and the substrate 10 for fixed connection, and the fastener 210 includes a connecting bolt, a connecting screw, or a connecting buckle, the stability and reliability of the connection can be enhanced. Through the fixation of the fastener 210, the connection between the pressing plate 20 and the substrate 10 is more stable and reliable, can withstand greater external forces and impacts, and maintain the long-term stable operation of the device. According to different installation environments and requirements, a suitable fastener 210 can be selected for installation. For example, a connecting buckle can be selected when the space is limited, and a connecting bolt or a connecting screw can be selected when higher fastening force is required.

[0034] Furthermore, the sealing and mounting member 30 is arranged in a sheet-like structure, and there is a predetermined distance between the outer edge of the sheet-like structure and the outer edges of both the pressing plate 20 and the substrate 10, and the fastener 210 is located on the outer peripheral side of the sheet-like structure. Having a predetermined distance between the outer edge of the sheet-like structure and the outer edges of both the pressing plate 20 and the substrate 10 helps to reduce the friction and wear generated due to the direct contact between the mounting member and the surrounding components, thereby extending the service life of the sealing and mounting member 30. At the same time, the predetermined distance can ensure that the sealing member will not affect its sealing performance due to being too tight or too loose during the installation process. The sheet-like sealing and mounting member 30 can fit more closely to the surface to be sealed, reducing the risk of leakage.

[0035] Furthermore, the aperture of the first wire threading hole 11 is larger than the outer diameter of the cable 40, and the aperture of the second wire threading hole 21 is larger than the outer diameter of the cable 40. Since the aperture of the wire threading hole is larger than the outer diameter of the cable 40, the cable 40 will not be excessively squeezed or rubbed during the threading process, thereby reducing the risk of damage to the outer skin of the cable 40 and contributing to extending the service life of the cable 40. The larger aperture makes it smoother for the cable 40 to pass through, reducing the threading difficulty and time consumption caused by too small an aperture, contributing to improving the construction efficiency and reducing the construction cost. The cable 40 may expand or contract due to temperature changes during operation. The larger aperture of the wire threading hole reserves enough space for the expansion of the cable 40, avoiding compression deformation or damage of the cable 40 caused by insufficient space.

[0036] Furthermore, the sealing mount 30 includes a rubber sheet, and / or the base plate 10 includes an insulating plate, and / or the pressing plate 20 includes an insulating plate. The rubber sheet has good elasticity and plasticity, can closely adhere to the sealing surface to form an effective seal, and can significantly improve the overall sealing performance. The base plate 10 is provided as an insulating plate, which can indirectly enhance the sealing effect by providing the function of isolating current in the case where both electrical insulation and sealing performance need to be considered simultaneously. By setting the pressing plate 20 as an insulating plate, it can effectively isolate current and prevent the occurrence of electric leakage. It can significantly improve the electrical safety of the entire electrical device and reduce the risk of safety accidents caused by electrical failures.

[0037] For the sake of convenience in description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0038] In addition, it should be noted that using words such as "first", "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above words have no special meaning, so it cannot be understood as a limitation on the protection scope of the present utility model.

[0039] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
