Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial cabinet technology, and in particular to a waterproof wiring structure for an industrial cabinet and an outdoor energy storage cabinet. Background Technology
[0002] Industrial server racks typically house various electronic devices that need to connect to external equipment for communication, power supply, or other functions. These devices connect via wiring harnesses, necessitating cable entry points on the rack. However, most industrial server racks are located outdoors, where rain and snow can easily enter through these entry points, causing corrosion and damage to the internal electronic equipment and affecting its performance.
[0003] To meet waterproofing requirements, cable glands are typically installed at the cable entry points of industrial cabinets. The cable harness passes through the cable gland to connect the equipment inside and outside the cabinet. After the cable gland is tightened, it clamps the surface of the cable harness to ensure waterproofing.
[0004] However, connectors are usually connected to both ends of the wire harness for quick connection to electronic devices. The connector cannot pass through the gland, so the wire harness must be cut and then passed through the gland before being reconnected to the connector, which affects the wire pulling efficiency. Using a large-sized gland to allow the connector to pass through directly does not clamp the wire harness surface properly, resulting in poor waterproofing. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a waterproof wiring structure for industrial cabinets and an outdoor energy storage cabinet, which can achieve wiring without cutting the wire harness and improve waterproof performance.
[0006] To achieve the above objectives, this utility model provides a waterproof wiring structure for industrial cabinets, applied to wire harness assemblies in industrial cabinets. The wire harness assembly includes a wire harness and a first connector and a second connector connected to both ends of the wire harness. The waterproof wiring structure includes: a gland, connected to the industrial cabinet, the inner diameter of the gland being larger than the maximum outer dimension of the first connector or the second connector, the gland connecting the internal and external spaces of the industrial cabinet to allow the wire harness assembly to pass through; and a waterproof sleeve, detachably connected to the gland, the waterproof sleeve including a wire guide portion and a wire inlet, the wire guide portion including a wire through hole. When the waterproof sleeve is connected to the gland, the wire through hole is coaxial with the gland, the wire inlet communicating with the wire through hole, the wire harness entering the wire through hole through the wire inlet, and the gland clamping the wire harness within the wire through hole by the waterproof sleeve.
[0007] Optionally, the wire guide portion is cylindrical, the wire guide hole passes through both ends of the wire guide portion along its axial direction, and the waterproof sleeve further includes a wire guide portion, which is frustum-shaped, with the wire guide opening passing through both ends of the wire guide portion along its axial direction. The wire guide portion is connected to one end of the wire guide portion, the outer diameter of the wire guide portion is smaller than the inner diameter of the gland, and the outer diameter of the wire guide portion is larger than the inner diameter of the gland.
[0008] Optionally, the wire opening is flared, and the smaller diameter end of the wire opening is connected to the wire through hole. The wire harness and the first connector pass through the wire opening and the wire through hole.
[0009] Optionally, the wire passage includes an inlet and an outlet, the diameter of the inlet being larger than the diameter of the outlet, and the inlet being connected to the smaller diameter end of the wire opening.
[0010] Optionally, the wire opening is a V-shaped groove, which is located on the side wall of the wire guide portion and extends through both ends of the wire guide portion. The bottom of the V-shaped groove is connected to the wire guide hole, and the wire harness enters the wire guide hole through the V-shaped groove.

[0013] Optionally, the waterproof sleeve is made of rubber material.
[0014] This utility model also provides an outdoor energy storage cabinet, including the wiring and waterproof structure of the industrial cabinet described in any of the above claims.
[0015] Compared with the prior art, the technical solution of this utility model has the following advantages: the inner diameter of the gland is larger than the maximum outer size of any connector in the wire harness assembly, allowing the connector to directly pass the wire harness through the gland without cutting the wire harness; the wire harness passes through a waterproof sleeve before directly passing through the gland, and the waterproof sleeve is then inserted into the gland, so that when the gland is locked, the waterproof sleeve clamps the surface of the wire harness, achieving a waterproof effect. The waterproof sleeve is made of easily deformable elastic plastic material, which can undergo elastic deformation when the connector passes through, facilitating the connector's passage, and recovers its shape after the connector passes through, facilitating the clamping of the wire harness.

[0032] Industrial server racks are mostly installed outdoors, exposed to rain and snow, therefore requiring a certain level of waterproofing to prevent liquids such as rain and snow from entering the rack and damaging the internal electronic equipment. The electronic equipment inside the rack needs to connect to external devices for communication, power supply, or other electrical functions. For example... Figure 1As shown, the industrial cabinet includes a cabinet panel 3 and a wiring harness assembly. The wiring harness assembly includes a wiring harness 41, a first connector 42, and a second connector 43. The cabinet panel 3 has a cable pass-through opening through which the wiring harness 41 passes. The first connector 42 and the second connector 43 connect to the two ends of the wiring harness 41, respectively. The first connector 42 is used to connect to electronic equipment inside the cabinet, and the second connector 43 is used to connect to equipment outside the industrial cabinet. To prevent liquid from entering the cabinet through the cable pass-through opening, this invention provides a waterproof cable pass-through structure that provides waterproofing during the cable pass-through process, enabling the industrial cabinet to meet the corresponding waterproofing requirements.
[0033] Example 1
[0034] Please refer to Figures 1 to 4 This is a schematic diagram of the wiring and waterproofing structure of the industrial cabinet provided in Embodiment 1 of this utility model. Figure 1 As shown, the waterproof wiring structure includes a gland 1 and a waterproof sleeve 2. The gland 1 connects to the wiring port on the cabinet panel 3, with one end located inside the industrial cabinet and the other end outside. A wiring channel runs through the gland 1, allowing the wire harness assembly to pass through. This channel connects the internal and external spaces of the industrial cabinet, and its diameter must be larger than that of the first connector 42 or the second connector 43 to ensure the wire harness assembly can pass smoothly. In this embodiment, the first connector 42 passes through the gland 1; therefore, the diameter of the wiring channel is at least larger than the maximum external dimension of the first connector 42. The waterproof sleeve 2 is detachable from the gland 1. During wiring, the waterproof sleeve 2 is first separated from the gland 1. After the wire harness assembly passes through the waterproof sleeve 2 and the gland 1 in sequence, the waterproof sleeve 2 is then inserted back into the gland 1.
[0035] like Figure 2 and Figure 3As shown, the waterproof sleeve 2 includes a wire guide portion 21 and a wire guide portion 22. The wire guide portion 21 has a wire guide hole 211 that passes through both ends of the wire guide portion 21. When the waterproof sleeve 2 is connected to the gland 1, the wire guide portion 21 is located within the wire passage. The wire guide hole 211 is coaxial with the gland 1, thus connecting the internal and external spaces of the industrial cabinet. The wire harness assembly extends from both ends of the gland 1 through the wire guide hole 211. The wire guide portion 22 is connected to the wire guide portion 21 and communicates with the wire guide hole 211. The wire harness assembly enters the wire guide hole 211 through the wire guide portion 22 and is guided through the waterproof sleeve 2 by the wire guide portion 22, improving the wire threading efficiency. In this embodiment, when the waterproof sleeve 2 is connected to the gland 1, the cable guide 21 is located inside the cable guide channel, filling the space inside the cable guide channel of the gland 1, preventing liquid from entering the industrial cabinet from the cable guide channel. The waterproof sleeve 2 is made of rubber or other easily elastic and deformable plastic materials. When the gland 1 is clamped, the waterproof sleeve 2 is squeezed, reducing the cable guide hole 211, so that the side wall of the cable guide 21 clamps the wire harness 41, preventing liquid from entering the industrial cabinet from the cable guide hole 211, thereby improving the waterproof performance.
[0036] like Figure 3 As shown, the wire guide section 21 is cylindrical, with a wire guide hole 211 located at the center of the cylinder and extending through both ends along the axial direction. The two ends of the wire guide hole 211 are the inlet 212 and the outlet 213, respectively. The diameter of the inlet 212 is larger than the diameter of the outlet 213, resulting in a trapezoidal cross-section for the entire wire guide hole 211. The wall thickness of the wire guide section 21 also changes from thin to thick. The inlet 212 has a larger diameter and thinner wall, making it easier to deform and allowing the first connector 42 to pass through smoothly. The outlet 213 has a smaller diameter and thicker wall, facilitating the clamping of the wire bundle 41. The conductor section 22 is frustum-shaped, with a flared conductor opening 221 at its center. The conductor opening 221 extends through both ends along the axial direction of the conductor section 22 and includes a small-diameter end and a large-diameter end. The small-diameter end connects to the inlet 212, thus connecting the conductor opening 221 to the wire guide hole 211. The outer diameter of the conductor portion 22 is larger than the diameter of the cable passage, which is larger than the inner diameter of the gland 1. Therefore, the conductor portion 22 is located outside the gland 1 and can seal one end of the cable passage to prevent liquid from entering the cable passage from that end, further improving the waterproof performance. In this embodiment, the diameter of the large-diameter end of the conductor opening 221 is larger than the outer dimension of the first connector 42, the diameter of the small-diameter end is larger than the diameter of the inlet 212, and the diameter of the outlet 213 is larger than the wire diameter of the wire harness 41.
[0037] like Figure 2 and Figure 4As shown, the gland 1 includes a separable body 11, a waterproof ring 12, a tightening nut 13, and a nut 14. During installation, the wire harness 41 is first folded in half and inserted through the wire inlet 221, then passed through the wire throughlet 211. The first connector 42 is pulled through the wire throughlet 21 by pulling the wire harness 41. The first end of the body 11 is located on the outside of the cabinet panel 3 and connected to the nut 14. The second end of the body 11 passes through the wire throughlet 3 and is located on the inside of the cabinet panel 3. A rubber gasket is provided between the body 11 and the inside of the cabinet panel 3 for sealing. The connector 42 enters from the first end of the main body 11 and passes through the waterproof ring 12 and the clamping nut 13 in sequence. Then, the waterproof sleeve 2 is inserted into the main body 11 from the first end, so that the wire passage 21 is located inside the main body 11, that is, inside the wire passage channel. The waterproof ring 12 is fitted on the wire passage 21. The inner diameter of the waterproof ring 12 is larger than the outer diameter of the wire passage 21, or is adapted. The second end of the main body 11 is then threadedly connected to the clamping nut 13, thereby clamping and fixing the gland 1 to the cabinet plate 3, and squeezing the waterproof sleeve 2 to clamp the wire harness, thus achieving waterproof wire passing.
[0038] Example 2
[0039] Please refer to Figure 5 and Figure 6 This is a schematic diagram of the waterproof sleeve provided in Embodiment 2 of this utility model. The difference between Embodiment 2 and Embodiment 1 is that the wire guide portion has a V-shaped groove 222. The V-shaped groove 222 is formed on the side wall of the wire guide portion 21, and the bottom of the V-shaped groove 222 communicates with the wire guide hole 211. The wire harness 41 can be directly inserted into the wire guide hole 211 through the opening of the V-shaped groove 222. Then, the first connector 42 directly passes through the gland 1, and the waterproof sleeve 2 is then inserted into the gland 1. When the gland 1 is locked, it squeezes the waterproof sleeve 2, closing the V-shaped groove 222 and achieving waterproofing. By forming a V-shaped groove 222 on the wire guide portion 21 that communicates with the wire guide hole 211, the wire harness 41 can directly enter the waterproof sleeve 2, and the first connector 42 does not need to pass through the waterproof sleeve 2, improving the threading efficiency.
[0040] The difference between Embodiment 2 and Embodiment 1 is that the wire guide portion 21 includes a first cylinder 215 that can extend into the gland 1 and a second cylinder 216 located outside the gland 1. The diameter of the first cylinder 215 is smaller than the inner diameter of the gland 1 and smaller than the inner diameter of the waterproof ring 12. The diameter of the second cylinder 216 is larger than the inner diameter of the gland 1, which can block the wire guide channel and prevent liquid from entering. The diameter of the wire guide hole 211 is larger than the wire diameter of the wire harness 41.
[0041] Example 3
[0042] Please refer to Figure 7This is a schematic diagram of the end of the waterproof sleeve provided in Embodiment 3 of this utility model. The difference between Embodiment 3 and Embodiment 2 is that the conductor portion 22 is a side "Z"-shaped groove 223, with a cross-section in the shape of a side "Z". The bottom opening of the side "Z"-shaped groove 223 communicates with the wire passage hole 211, and the top opening is connected to the bottom opening in a zigzag manner. The middle of the side "Z"-shaped groove 223 separates the side wall of the wire passage portion 21 into upper and lower layers. The wire harness 41 is inserted from the top opening, passes through the middle, and then enters the wire passage hole 211 from the bottom opening. Then, the first connector 42 directly passes through the gland 1, and the waterproof sleeve 2 is inserted into the gland 1. When the gland 1 is locked, it compresses the waterproof sleeve 2, sealing the side "Z"-shaped groove and achieving waterproofing. By setting the conductor portion as a side "Z"-shaped groove, the conductor portion can be sealed more tightly when compressed, further improving the waterproof performance.
[0043] This invention, by setting a waterproof sleeve that can be separated from the gland, allows for the use of a larger gland when there is a significant difference in diameter between the connector and the wire harness in the wiring harness assembly. This allows the connector to pass directly through without cutting the wire harness, and the waterproof sleeve is then inserted into the gland to clamp the wire harness, thus meeting the waterproof requirements for wiring in industrial cabinets.
[0044] This utility model also provides an outdoor energy storage cabinet, which has an energy storage battery pack installed inside. The energy storage battery pack communicates with an external energy storage converter via a signal harness. The outdoor energy storage cabinet has a wiring port on the cabinet door, and the wiring port is equipped with the waterproof wiring structure described in the above embodiments. The signal harness is connected to the energy storage battery pack and the energy storage converter respectively through the waterproof wiring structure.
[0045] Although the embodiments are described and illustrated separately above, some common technologies are involved. Those skilled in the art can replace and integrate them between the embodiments. If there is any content not explicitly described in one embodiment, then another embodiment that is described can be referred to.
[0046] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
