Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a sealing joint connector for cable trays. Background Technology

[0002] Cable trays are commonly used support and protection devices for cable laying in electrical equipment power supply systems, serving to protect and guide the cables laid within them. Cable trays are widely used in cable laying in buildings, industrial plants, data centers, and other locations.

[0003] Adjacent cable tray sections are typically connected using connectors, but traditional connectors have the following drawbacks:

[0004] 1. Unsightly seams: After connection, obvious gaps will form at the joints of the cable trays, affecting the overall aesthetics.

[0005] 2. Insufficient strength at the connection points and lack of structural reinforcement at the joints may lead to deformation of the cable tray under the long-term action of cable gravity load;

[0006] 3. Limited functionality: Existing connectors primarily address connection issues, rarely considering both aesthetics and structural reinforcement. While seams can be beautified later through methods like applying glue, the process is cumbersome, the effect is not lasting, and it cannot solve the strength problem. Adding additional reinforcing ribs would increase costs and installation complexity.

[0007] 4. There is a risk of cable damage at the joints. The edges of the cable tray may have burrs that can easily scratch the cable sheath and damage the cable insulation layer. Utility Model Content

[0008] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a joint sealing connector for cable trays, so as to solve the technical problems such as unsightly joints and insufficient strength of the connection in the existing technology.

[0009] This utility model is achieved by the following technical solution: a grout connector for cable trays, the grout connector including a ridge and two snap-fit ​​portions respectively disposed on both sides of the ridge;

[0010] The ridge is arched;

[0011] The two locking parts are symmetrically arranged, and each locking part has a locking groove with an outward opening. The bottom wall ends of two adjacent cable trays are respectively inserted into the two locking grooves.

[0012] In one possible implementation, the ridge portion and the snap-fit ​​portion are connected by a first arc transition portion.

[0013] In one possible implementation, a gap exists between the two snap-fit ​​portions.

[0014] In one possible implementation, the snap-fit ​​portion is U-shaped.

[0015] In one possible implementation, the snap-fit ​​portion is clearance-fitted with the bottom wall of the cable tray.

[0016] In one possible implementation, a reinforcing plate is further included, which is connected to the side of the snap-fit ​​portion away from the ridge portion, and the reinforcing plate is located directly below the snap-fit ​​portion, with the upper surface of the reinforcing plate abutting against the lower surface of the snap-fit ​​portion.

[0017] In one possible implementation, the snap-fit ​​portion is connected to the reinforcing plate via a second arc transition portion.

[0018] In one possible implementation, the grout connector is a one-piece molded structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a sealant connector at the connection of two adjacent cable trays, the gap at the joint of the two cable trays is covered and concealed, thereby improving the aesthetics. In addition, the snap-fit ​​parts on both sides of the sealant connector can snap into the two cable trays respectively, thereby improving the connection strength of the two adjacent cable trays. The arched ridge can not only improve the overall structural strength of the sealant connector, but also reduce the wear on the cable, which is conducive to improving the service life of the cable.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0032] like Figure 1-3 The cable tray joint connector shown includes a raised ridge 1 and two snap-fit ​​parts 2 respectively disposed on both sides of the raised ridge 1; the raised ridge 1 is arched; the two snap-fit ​​parts 2 are symmetrically arranged, and each snap-fit ​​part 2 has a snap-fit ​​groove 21 with an outward opening, and the bottom wall ends of two adjacent cable trays are respectively inserted into the two snap-fit ​​grooves 21. It should be noted that the cross-section of the joint sealant is similar to a mushroom shape, which improves its aesthetics. The joint sealant is long and narrow, with the snap-fit ​​part 2 extending along its length. The raised ridge part 1 is located above the snap-fit ​​part 2 to cover the gap between adjacent cable trays. The raised ridge part 1 is arched. The setting of the raised ridge part 1 can significantly increase the moment of inertia of the joint sealant, thereby improving its bending resistance and enhancing the connection strength between the joint sealant and the cable tray. This allows it to effectively bear and transfer the load at the cable tray connection, preventing the connection from becoming a weak point. It improves the overall load-bearing capacity and deformation resistance of the cable tray system, extends its service life, and effectively solves the problem of insufficient strength at traditional cable tray joints.

[0033] It is easy to understand that this grout sealant connector usually needs to be used together with other cable tray connectors. Other connectors are usually set on the side wall of the cable tray to achieve a fixed connection between two adjacent cable trays. After connection, if there is a gap between the cable trays, the grout sealant connector can be used. For example, in the novel patent "A Clamp-Type Cable Tray Connection Assembly" filed before this application, there is a gap between the cable trays after connection, and the grout sealant connector can be applied here.

[0034] Furthermore, the grout connector integrates connection, grouting, and reinforcement functions into one compact and reasonable structure. It can be installed between two sections of cable tray without the need for additional screws, special tools, or complicated procedures, resulting in high installation efficiency. It is also suitable for various common types of metal or non-metal cable trays, such as tray type and ladder type.

[0035] The beneficial effects of this utility model are as follows: by setting a joint sealant at the connection of two adjacent cable trays, the gap at the joint of the two cable trays is covered and concealed, thereby improving the aesthetics. In addition, the snap-fit ​​parts 2 on both sides of the joint sealant can snap-fit ​​with the two cable trays respectively, thereby improving the connection strength of the two adjacent cable trays. The arched ridge 1 can not only improve the overall structural strength of the joint sealant, but also reduce the wear on the cable, which is conducive to improving the service life of the cable.

[0036] Please refer to Figure 2 In one possible implementation, the ridge 1 and the snap-fit ​​part 2 are connected by a first arc transition part 3. It is easy to understand that connecting the ridge 1 and the snap-fit ​​part 2 by the first arc transition part 3 avoids the risk of the cable being easily scratched, improves the safety and aesthetics of the grout connector, and enhances the overall structural strength of the grout connector.

[0037] Please refer to Figure 2 In one possible implementation, a gap exists between the two locking portions 2. It should be noted that the gap prevents the two locking portions 2 from directly contacting each other, thus avoiding friction. Furthermore, since the ridge 1 is arched, when the grout connector is impacted by the cable tray, it may undergo slight elastic deformation, causing the locking portions 2 to shift inwards. The gap acts as a buffer, preventing impact between the two locking portions 2 and improving the service life of the grout connector.

[0038] Please refer to Figure 2 In one possible implementation, the latching part 2 is U-shaped. It should be noted that the U-shape of the latching part 2 can form a latching groove 21 into which the cable tray extends, and the bottom of the latching part 2 is flat, so that the cable tray can contact the bottom wall of the latching groove 21 after it is extended, so that the latching part 2 and the cable tray are more stably latched.

[0039] Please refer to Figure 3 In one possible implementation, the snap-fit ​​part 2 is clearance-fitted with the bottom wall of the cable tray. It should be noted that the size of the snap-fit ​​groove 21 is adapted to the thickness of the bottom wall of the cable tray, which allows the bottom wall of the cable tray to be smoothly inserted into the snap-fit ​​groove 21, and also prevents the bottom wall of the cable tray from shifting too much after being inserted into the snap-fit ​​groove 21, thereby improving the stability of the connection between the sealant connector and the cable tray.

[0040] Please refer to Figure 1 In one possible implementation, a reinforcing plate 4 is also included. The reinforcing plate 4 is connected to the side of the snap-fit ​​portion 2 away from the ridge portion 1, and the reinforcing plate 4 is located directly below the snap-fit ​​portion 2. The upper surface of the reinforcing plate 4 is in contact with the lower surface of the snap-fit ​​portion 2. It should be noted that there are also two reinforcing plates 4, each connected to one of the two snap-fit ​​portions 2. The addition of the reinforcing plate 4 can improve the structural strength of the lower sidewall of the snap-fit ​​portion 2, thereby improving the support strength of the grout connector for the cable tray, so as to prevent the lower sidewall of the snap-fit ​​portion 2 from accidentally bending when the cable is too heavy, causing the cable tray to detach from the grout connector.

[0041] Please refer to Figure 1 In one possible implementation, the snap-fit ​​part 2 is connected to the reinforcing plate 4 via a second arc transition part 5. It should be noted that the connection between the snap-fit ​​part 2 and the reinforcing plate 4 via the second arc transition part 5 avoids the risk of the snap-fit ​​part 2 easily scratching the cable tray, and helps improve the safety and aesthetics of the grout connector, as well as enhance the overall structural strength of the grout connector.

[0042] Please refer to Figure 1 In one possible implementation, the grout connector is a one-piece molded structure. It should be noted that the ridge 1, the first arc transition portion 3, the snap-fit ​​portion 2, the second arc transition portion 5, and the reinforcing plate 4 are a one-piece molded structure. The first arc transition portion 3 and the second arc transition portion 5 serve as bending points. Preferably, the grout connector can be integrally molded from a metal sheet by stamping, which improves the overall structural strength of the grout connector. Furthermore, the arc-shaped structure on the grout connector can further improve its bending and torsional resistance.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
