Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a through-wall terminal structure. Furthermore, this utility model also relates to a cabinet assembly including the aforementioned through-wall terminal structure. Background Technology

[0002] Through-wall terminals are widely used between various electrical devices. They are an accessory product used to achieve electrical connections, mainly serving the functions of sealing and dust prevention.

[0003] In existing rack networking solutions, the common electrical connection methods are two types: metal channel hard connection and rubber channel soft connection.

[0004] Among them, the metal channel hard connection solution requires a stable relative position relationship when assembling multiple cabinets, so it needs to be shipped together after merging the cabinets. The overall volume is large and heavy, and it is not conducive to on-site installation.

[0005] The rubber channel flexible connection solution has relatively low requirements for the relative position relationship of multiple cabinets during assembly and can meet the needs of on-site connection. However, its outermost layer is made of rubber insulation material, which is easily affected by the environment and hardens. It is also easily bitten by rodents, causing the seal to fail, and has poor adaptability to the field environment.

[0006] In summary, how to solve the problems of existing electrical connection methods, such as high requirements for the relative position of cabinets when paralleling, unsuitability for on-site installation, and poor adaptability to outdoor environments, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a through-wall terminal structure that uses a gap fit between the sleeve parts of two components to reduce the relative position requirements of the two cabinets when connecting them, improve the flexibility of installation, and facilitate on-site installation. At the same time, a sealing ring is set between the two sleeve parts, and the sealing between the two sleeve parts is achieved by compressing the sealing ring, that is, the sealing of the connection position of the two cabinets is achieved. Moreover, the sealing ring is located between the two sleeves, which effectively reduces its contact with the external environment, slows down its hardening speed, and avoids sealing failure caused by rodents gnawing.

[0008] Another objective of this utility model is to provide a cabinet assembly that includes the above-mentioned through-wall terminal structure, has the same technical features, and can solve the same technical problems.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A through-wall terminal structure for electrical connections in cabinet networking;

[0011] The through-wall terminal structure includes:

[0012] The first component includes a first sleeve portion and a first fixing portion that are fixedly connected to each other.

[0013] The second component includes a second sleeve portion and a second fixing portion that are fixedly connected to each other.

[0014] The second sleeve portion is fitted with the first sleeve portion with a clearance fit, and a sealing ring is provided between the adjacent surfaces of the second sleeve portion and the first sleeve portion to seal the gap between the first sleeve portion and the second sleeve portion by compression.

[0015] Preferably, the sealing ring is a toothed sealing ring.

[0016] Preferably, both the first sleeve portion and the second sleeve portion are rectangular structures, and the width difference between the first sleeve portion and the second sleeve portion along the first direction is greater than the width difference along the second direction, wherein the first direction is perpendicular to the second direction.

[0017] Preferably, the sealing ring has a rectangular structure, and the thickness of the sealing ring along the first direction is greater than its thickness along the second direction.

[0018] Preferably, one end of the first sleeve portion is folded outward to form the first fixing portion, and a first gasket is provided between the end face of the first fixing portion and the mounting surface of the cabinet.

[0019] And / or,

[0020] One end of the second sleeve is folded outward to form the second fixing part, and a second gasket is provided between the end face of the second fixing part and the mounting surface of the cabinet.

[0021] Preferably, the first sleeve portion is nested outside the second sleeve portion;

[0022] The second component has a support part for fixing the copper busbar relative to the second component.

[0023] Preferably, the outer wall of the second sleeve portion is provided with an auxiliary fixing part for fixing the sealing ring.

[0024] Preferably, the second sleeve portion is nested outside the first sleeve portion;

[0025] The first component has a support part for fixing the copper busbar relative to the first component.

[0026] Preferably, the outer wall of the first sleeve portion is provided with an auxiliary fixing part for fixing the sealing ring.

[0027] A cabinet assembly, comprising the through-wall terminal structure described in any one of the above.

[0028] The through-wall terminal structure provided by this utility model has at least the following advantages compared with the prior art:

[0029] 1. By using the sleeve gap fit of the two components for installation, a certain amount of redundancy is allowed in the relative position of the two components during installation. This reduces the requirements for the relative position of the two cabinets when they are combined, making it suitable for on-site installation and avoiding the problems of transporting large items.

[0030] 2. A sealing ring is installed between the two sleeve parts that are fitted with a gap. By compressing the sealing ring, a seal is achieved between the two sleeve parts, that is, a seal is achieved at the connection position of the two cabinets. Since the sealing ring is located between the two sleeve parts, the contact between the sealing ring and the external environment is reduced, thereby reducing the impact of the environment on its service life. At the same time, it also prevents rodents from biting the sealing ring, thus avoiding its sealing failure.

[0031] The cabinet assembly provided by this utility model includes the above-mentioned through-wall terminal structure and has the same beneficial effects. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The core of this utility model is to provide a through-wall terminal structure, which adopts a gap fit between the sleeve parts of two components, reducing the relative position requirements of the two cabinets when connecting them, improving the flexibility of installation, and making it easier to install on site; at the same time, a sealing ring is set between the two sleeve parts, and the sealing between the two sleeve parts is achieved by compressing the sealing ring, that is, the sealing of the connection position of the two cabinets is achieved, and the sealing ring is located between the two sleeves, which effectively reduces its contact with the external environment, slows down its hardening speed, and avoids sealing failure caused by rodents gnawing.

[0041] Another core aspect of this utility model is to provide a cabinet assembly that includes the above-mentioned through-wall terminal structure, which has the same technical features and can solve the same technical problems.

[0042] Please refer to Figures 1-3 A through-wall terminal structure for electrical connections in cabinet networking;

[0043] The through-wall terminal structure includes:

[0044] The first component 1 includes a first sleeve portion 12 and a first fixing portion 13 that are fixedly connected to each other.

[0045] The second component 2 includes a second sleeve portion 22 and a second fixing portion 23 that are fixedly connected to each other.

[0046] The second sleeve portion 22 is fitted with the first sleeve portion 12 with a clearance fit, and a sealing ring 3 is provided between the adjacent surfaces of the second sleeve portion 22 and the first sleeve portion 12 to seal the gap between the first sleeve portion 12 and the second sleeve portion 22 by compression.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, both the first component 1 and the second component 2 include a sleeve portion and a fixing portion. The fixing portion is used to fix the component to the corresponding installed cabinet, and the sleeve portion is used for the copper busbar 5 to pass through. The first sleeve portion 12 of the first component 1 and the second sleeve portion 22 of the second component 2 are connected by a clearance fit installation method, that is, there is a certain margin between the first sleeve portion 12 and the second sleeve portion 22 to meet the non-coaxial installation of the first sleeve portion 12 and the second sleeve portion 22. Therefore, when merging cabinets, the relative position relationship of the first sleeve portion 12 and the second sleeve portion 22 can be adjusted in real time according to the relative position of the two sets of cabinets, thereby meeting the relative position of the cabinets on site and reducing the difficulty.

[0048] Meanwhile, a sealing ring 3 is provided in the middle of the overlapping position of the first sleeve part 12 and the second sleeve part 22. During assembly, the sealing ring 3 is deformed by the compression of the first sleeve part 12 and the second sleeve part 22, thereby sealing the gap between the first sleeve part 12 and the second sleeve part 22, thus completing the sealing of the connection position of the two sets of cabinets. Since the sealing ring 3 is located in the gap between the first sleeve part 12 and the second sleeve part 22, the contact between the sealing ring 3 and the external environment is effectively reduced, avoiding hardening of the sealing ring 3 caused by the external environment, and ensuring its long-lasting sealing performance. At the same time, the sealing ring 3 is protected by its outer sleeve part, effectively preventing rodents from gnawing on it, thereby avoiding the loss of its sealing performance.

[0049] In some embodiments, the sealing ring 3 is a toothed sealing ring.

[0050] like Figure 2 As shown, the sealing ring 3 is a closed-loop annular structure with toothed structures on its inner and / or outer annular surfaces. Therefore, when the sealing ring 3 is subjected to radial compression, it has a larger radial deformation, thereby enabling the first sleeve portion 12 and the second sleeve portion 22 to obtain a larger radial adjustment space.

[0051] In some embodiments, the first sleeve portion 12 and the second sleeve portion 22 are both rectangular structures, and the width difference between the first sleeve portion 12 and the second sleeve portion 22 along the first direction is greater than the width difference along the second direction, and the first direction is perpendicular to the second direction.

[0052] like Figure 2 As shown, both the first sleeve portion 12 and the second sleeve portion 22 are rectangular structures. The first sleeve portion 12 and the second sleeve portion 22 require more adjustment space in the first direction, which is the length direction, than in the second direction, which is the width direction. Therefore, the width difference between the first sleeve portion 12 and the second sleeve portion 22 in the first direction is greater than the width difference in the second direction, so that the first sleeve portion 12 and the second sleeve portion 22 have a larger adjustment space in the first direction.

[0053] In some embodiments, the first sleeve portion 12 and the second sleeve portion 22 are both circular structures with different diameters, but the adjustment space in each direction is the same.

[0054] In some embodiments, the sealing ring 3 has a rectangular structure, and the thickness of the sealing ring 3 along the first direction is greater than its thickness along the second direction.

[0055] like Figure 2 As shown, when the width difference between the first sleeve portion 12 and the second sleeve portion 22 in the two directions is different, the sealing ring 3 that is adapted to it also has different thicknesses in different directions, thereby avoiding excessive local compression deformation of the sealing ring 3 and ensuring its sealing performance.

[0056] In some embodiments, one end of the first sleeve portion 12 is folded outward to form a first fixing portion 13, and a first gasket 11 is provided between the end face of the first fixing portion 13 and the mounting surface of the cabinet.

[0057] And / or,

[0058] One end of the second sleeve portion 22 is folded outward to form a second fixing portion 23, and a second gasket 21 is provided between the end face of the second fixing portion 23 and the mounting surface of the cabinet.

[0059] like Figure 2 and Figure 3 As shown, both the first component 1 and the second component 2 are composed of a sleeve part and a fixing part, and the fixing part is located at one end of the sleeve part. The fixing part is formed by folding and extending one end of the sleeve part outward. In some embodiments, the fixing part is vertically welded to the outer wall of the sleeve part, and the welding position is sealed.

[0060] When the first component 1 and / or the second component 2 are installed, their sleeve part passes through the through hole of the cabinet from inside the cabinet, the fixing part abuts against the inner wall of the cabinet and seals, and a gasket is added between the fixing part and the inner wall of the cabinet to improve the sealing performance.

[0061] The copper busbar 5, used for electrical connection, runs directly through the sleeve to achieve electrical connection between the components in the two cabinets.

[0062] In some embodiments, the first sleeve portion 12 is nested outside the second sleeve portion 22;

[0063] The second component 2 is provided with a support part 4, which is used to fix the copper busbar 5 relative to the second component 2.

[0064] like Figure 1 and Figure 3As shown, the diameter of the first sleeve portion 12 is larger than that of the second sleeve portion 22. Therefore, the first sleeve portion 12 is fitted onto the outside of the second sleeve portion 22. The second sleeve portion 22, which is located in the inner layer, is provided with a support portion 4 for fixing the second sleeve portion 22 to the copper busbar 5.

[0065] like Figure 4 As shown, the support part 4 is fixedly connected to the inner wall of the second sleeve part 22, and the copper busbar 5 passes through the sleeve structure of the support part 4. The inner wall of the sleeve structure is provided with a protrusion. When the copper busbar 5 passes through the sleeve structure, the limiting groove on the side wall of the copper busbar 5 can cooperate with the protrusion on the inner wall of the sleeve structure to achieve relative fixation between the copper busbar 5 and the support part 4, thereby limiting the relative position between the copper busbar 5 and the second component 2. In practical applications, by setting the support part 4, the second component 2 can support the copper busbar 5 and prevent the copper busbar 5 from being continuously subjected to force and strain.

[0066] In some embodiments, the outer wall of the second sleeve portion 22 is provided with an auxiliary fixing portion for fixing the sealing ring 3.

[0067] like Figure 3 As shown, when the diameter of the second sleeve portion 22 is smaller than that of the first sleeve portion 12, an auxiliary fixing portion, preferably an annular groove, is provided on the outer wall of the second sleeve portion 22 for fixing the sealing ring 3, so as to prevent the sealing ring 3 from being displaced when the first sleeve portion 12 and the second sleeve portion 22 are assembled.

[0068] In some embodiments, the second sleeve portion 22 is nested outside the first sleeve portion 12;

[0069] The first component 1 is provided with a support part 4, which is used to fix the copper busbar 5 relative to the first component 1.

[0070] If the diameter of the second sleeve portion 22 is larger than the diameter of the first sleeve portion 12, during assembly, the second sleeve portion 22 is fitted onto the outside of the first sleeve portion 12, while the support portion 4 for fixing the copper busbar 5 is provided inside the inner first sleeve portion 12.

[0071] In some embodiments, the outer wall of the first sleeve portion 12 is provided with an auxiliary fixing portion for fixing the sealing ring 3.

[0072] When the diameter of the second sleeve portion 22 is larger than that of the first sleeve portion 12, an auxiliary fixing portion, preferably an annular groove, is provided on the outer wall of the first sleeve portion 12 for fixing the sealing ring 3, so as to prevent the sealing ring 3 from being displaced when the first sleeve portion 12 and the second sleeve portion 22 are assembled.

[0073] In addition to the through-wall terminal structure disclosed in the above embodiments, this utility model also provides a cabinet assembly including the above-mentioned through-wall terminal structure. For the structure of other parts of the cabinet assembly, please refer to the prior art, which will not be described in detail here.
