Description
Technical Field
[0001] This disclosure relates to the field of dustproof and waterproof technology, and in particular to a sealing device and an electrical control cabinet. Background Technology
[0002] Electrical control cabinets, as devices used to assemble various electrical components and control and measurement devices, are often used in relatively harsh environments, such as mines in the field. Because of the harsh environment in which electrical control cabinets operate, and to protect the various electrical components inside from environmental influences such as dust and moisture, it is necessary to effectively seal the wiring holes at the wiring locations within the cabinet.
[0003] In related technologies, electrical control cabinets include a housing and a sealing device. The sealing device is generally a circular sealing ring. The sealing ring is located inside the cable passage hole and wraps around the cable. In this way, when the cable passes through the cable passage hole, it can be sealed by the sealing ring, thereby preventing moisture, dust, etc. from entering the electrical control cabinet from the cable passage hole.
[0004] However, since the sealing ring is located directly in the cable passage hole of the enclosure, it is very easy for the sealing ring to come off from the cable passage hole when the cable is pulled, thus affecting the sealing effect. Utility Model Content
[0005] This disclosure provides a sealing device and an electrical control cabinet, which can improve the sealing effect of the sealing device. The technical solution is as follows:
[0006] This disclosure provides a sealing device, which includes a sealing body for being disposed in a cable passage hole of an electrical control cabinet. The outer periphery of the sealing body has an annular groove for accommodating the side wall of the electrical control cabinet. The interior of the sealing body has a sealing hole for clamping cables.
[0007] In another implementation of this disclosure, the sealing body includes a first ring, a second ring, and an intermediate connecting ring. The intermediate connecting ring is located between the first ring and the second ring, and its two ends are respectively connected to the first ring and the second ring. The outer diameters of the first ring and the second ring are both larger than the outer diameter of the intermediate connecting ring. The outer edge of the first ring, the outer edge of the second ring, and the outer periphery of the intermediate connecting ring define the slot.
[0008] In another implementation of this disclosure, the first ring body has a first end face and a second end face arranged opposite to each other, the first end face being located on the side of the second end face away from the intermediate connecting ring body; the outer diameter of the first end face is smaller than the outer diameter of the second end face, and the outer periphery of the first end face has an arc-shaped first transition surface along the direction from the first end face to the second end face.
[0009] In another implementation of this disclosure, the second ring body has a third end face and a fourth end face arranged opposite to each other, the third end face being located on the side of the fourth end face away from the intermediate connecting ring body; along the direction from the third end face to the fourth end face, the outer periphery of the third end face has an arc-shaped second transition surface.
[0010] In another implementation of this disclosure, the sealing body is a plastic structural component capable of plastic deformation.
[0011] In another implementation of this disclosure, the sealing body has a slit that communicates with the sealing hole and extends through opposite sides of the sealing body along its axial direction.
[0012] In another implementation of this disclosure, the sealing body has a plurality of slits, which are spaced apart circumferentially along the sealing hole and, along the axial direction of the sealing body, each slit penetrates opposite sides of the sealing body.
[0013] In another implementation of this disclosure, the gap is linear, and the extension direction of each gap is radial to the sealing hole.
[0014] In another implementation of this disclosure, the plurality of said slits are arranged in pairs, and the two slits arranged in pairs are respectively located on the same diameter of the sealing hole.
[0015] On the other hand, this disclosure also provides an electrical control cabinet, which includes a housing and a sealing device. The sealing device is located in a wire passage hole on the side wall of the housing, and the sealing device is the sealing device described above.
[0016] The beneficial effects of the technical solutions provided in this disclosure are:
[0017] When the sealing device provided in this embodiment is used to seal the cable, since the sealing device includes a sealing body and the outer periphery of the sealing body has a groove for accommodating the side wall of the electrical control cabinet, and the groove wall is engaged with the electrical control cabinet, the sealing body can be engaged with the electrical control cabinet through the groove during assembly, thus preventing the sealing device from moving with the cable when the cable is pulled.
[0018] Furthermore, the interior of the sealing body has a sealing hole for clamping the cable, so the sealing hole can provide space for the cable, allowing the cable to achieve a sealed fit with the sealing body. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.
[0029] This disclosure provides a sealing device, such as... Figure 1 As shown, the sealing device includes a sealing body 1, which is used to be installed in the wire hole of the electrical control cabinet. The outer periphery of the sealing body 1 has an annular groove 101 for accommodating the side wall of the electrical control cabinet.
[0030] Figure 2 for Figure 1 The side view, combined with Figure 2 The interior of the sealing body 1 has a sealing hole 102 for clamping cables.
[0031] When the sealing device provided in this embodiment is used to seal the cable, since the sealing device includes a sealing body 1 and the outer periphery of the sealing body 1 has a groove 101 for accommodating the side wall of the electrical control cabinet, and the groove wall of the groove 101 is engaged with the electrical control cabinet, the sealing body 1 can be engaged with the electrical control cabinet through the groove 101 during assembly, thus preventing the sealing device from moving with the cable when the cable is pulled.
[0032] Furthermore, the interior of the sealing body 1 has a sealing hole 102 for clamping cables. Therefore, the sealing hole 102 can provide space for the cables, so that the cables can achieve a sealed fit with the sealing body 1, preventing the cables from being poorly sealed when passing through the electrical control cabinet.
[0033] See also Figure 1 Optionally, the sealing body 1 includes a first ring 11, a second ring 12, and an intermediate connecting ring 13.
[0034] The intermediate connecting ring 13 is located between the first ring 11 and the second ring 12, and its two ends are connected to the first ring 11 and the second ring 12 respectively.
[0035] The outer diameter of the first ring body 11 and the outer diameter of the second ring body 12 are both larger than the outer diameter of the intermediate connecting ring body 13. The outer edge of the first ring body 11, the outer edge of the second ring body 12, and the outer periphery of the intermediate connecting ring body 13 define the slot 101.
[0036] In the above implementation, the sealing body 1 is set as a structure, so that the slot 101 can be quickly and easily defined between the first ring 11, the second ring 12 and the intermediate connecting ring 13 with different outer diameters, thereby realizing the clamping of the sealing body 1 and the electrical control cabinet.
[0037] In this embodiment, in order to further simplify the manufacturing process of the sealing body 1, the sealing body 1 is an integral injection molded structural component.
[0038] In other examples, the sealing body 1 may also be a split structure, with the first ring 11, the second ring 12 and the intermediate connecting ring 13 bonded together by adhesives or the like.
[0039] Optionally, the first ring body 11 has a first end face 111 and a second end face 112 arranged opposite to each other, with the first end face 111 located on the side of the second end face 112 away from the intermediate connecting ring body 13.
[0040] The outer diameter of the first end face 111 is smaller than the outer diameter of the second end face 112. Along the direction from the first end face 111 to the second end face 112, the outer periphery of the first end face 111 has an arc-shaped first transition surface 113.
[0041] In the above implementation, the first ring body 11 is configured as described above, which allows the first ring body 11 to be configured as a ring with a gradually changing outer diameter at the end face, making it easier for the sealing body 1 to be inserted into the wire hole of the electrical control cabinet and improving assembly efficiency.
[0042] Optionally, the second ring body 12 has a third end face 121 and a fourth end face 122 arranged opposite to each other, with the third end face 121 located on the side of the fourth end face 122 away from the intermediate connecting ring body 13.
[0043] Along the direction from the third end face 121 to the fourth end face 122, the outer periphery of the third end face 121 has an arc-shaped second transition surface 123.
[0044] In the above implementation, the second ring 12 is configured as described above, which allows the second ring 12 to be configured as a ring with a gradually changing outer diameter at the end face, making it easier for the sealing body 1 to be inserted into the wire hole of the electrical control cabinet and improving assembly efficiency.
[0045] Optionally, the sealing body 1 is a plastic structural component with plastic deformation.
[0046] This can improve the sealing between the cable and the electrical control cabinet by plastic deformation of the sealing body 1, ensuring that the cable can be well sealed when passing through the electrical control cabinet.
[0047] In this embodiment, the sealing body 1 can be one of rubber sponge board, silicone sponge board, polyurethane foam board, and polyethylene foam board.
[0048] This allows the plastic deformation properties of the materials listed above to give the sealing body 1 good sealing performance.
[0049] Figure 3 for Figure 2 A structural diagram of the middle part, combined with Figure 3 Optionally, the sealing body 1 also has a slit 103, which is connected to the sealing hole 102.
[0050] Along the axial direction of the sealing body 1, the gap 103 extends through the opposite two sides of the sealing body 1.
[0051] In the above implementation, the gap 103 allows the sealing hole 102 to have a certain deformation capability, which not only facilitates the passage of cables, but also adapts to cables of different specifications.
[0052] Optionally, the sealing body 1 has multiple slits 103, which are distributed circumferentially along the sealing hole 102.
[0053] Along the axial direction of the sealing body 1, each slit 103 extends through the opposite two sides of the sealing body 1.
[0054] In the above implementation, multiple gaps 103 can be set to improve or enhance the deformation capability of the sealing hole 102, further facilitating the passage of cables.
[0055] Optionally, the gap 103 is straight, and the extension direction of each gap 103 is radial to the sealing hole 102.
[0056] In the above implementation, the gap 103 is set as a straight line, which facilitates the setting of the gap 103 and also makes it easier for the gap 103 to communicate with the sealing hole 102.
[0057] Optionally, the multiple slits 103 are arranged in pairs, with the two slits 103 arranged in pairs located on the same diameter of the sealing hole 102.
[0058] In the above implementation method, the above settings can further improve or enhance the deformation capability of the sealing hole 102, and further facilitate the cable to pass through.
[0059] In other words, in this embodiment, the gap 103 is arranged in a star shape, which can not only greatly improve the deformation ability of the sealing hole 102 and facilitate the cable to pass through, but also does not affect the sealing performance of the sealing body 1 on the cable.
[0060] In other examples, the shape and arrangement of the gap 103 can also be different, such as a groove shape, or an S-curve shape, etc.
[0061] On the other hand, this disclosure also provides an electrical control cabinet, which includes a housing and a sealing device, wherein the sealing device is located in a wire passage hole on the side wall of the housing, and the sealing device is the sealing device mentioned above.
[0062] The electrical control cabinets described above have the same beneficial effects as the aforementioned sealing devices, and will not be elaborated upon here.
[0063] The following is a brief introduction to the usage process of the sealing device provided in the embodiments of this disclosure:
[0064] When the sealing device provided in this embodiment is used in an electrical control cabinet, the sealing body 1 can be placed in the wire hole of the electrical control cabinet and the side wall of the electrical control cabinet can be placed in the slot 101 to achieve the snap-fit assembly between the sealing body and the electrical control cabinet.
[0065] Then the cable is passed through the sealing hole 102, which achieves the sealed assembly of the cable when it exits the electrical control cabinet.
[0066] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
