Description

Technical Field

[0001] This application relates to the field of cable tray technology, and in particular to a waterproof cable tray. Background Technology

[0002] Cable trays, also known as wiring ducts, are electrical tools used to neatly organize and fix power cords, data cables, and other wires to walls, ceilings, or underground. Cable trays are classified into various types depending on their materials, with common types including environmentally friendly PVC cable trays, halogen-free PPO cable trays, halogen-free PC / ABS cable trays, and metal cable trays such as steel and aluminum.

[0003] During installation, cable trays may need to be spliced ​​due to installation path or length issues. The two ends of the cable trays are connected by flanges or welding. If flanges are used, moisture can easily seep into the cable tray from the flange connection during long-term use. If welding is used, although it can achieve waterproof performance, the welded cable tray will cause trouble for later inspection or replacement, and welding will greatly increase the construction period.

[0004] Therefore, there is a need for a waterproof cable tray that can achieve waterproof performance while facilitating the assembly and disassembly of cable tray connections. Utility Model Content

[0041] Example:

[0042] See attached document Figure 1-7 This embodiment provides a waterproof cable tray, including:

[0043] Trunk body 1;

[0044] Connector 2, with its two ends respectively fitted onto the connecting ends of the two sections of the wire trough body 1 that need to be connected, so as to connect the two sections of the wire trough body 1 together.

[0045] The sealing sleeve 3 is fitted onto the connecting end of the two sections of the wire trough body 1, and the connecting end of the wire trough body 1 presses the sealing sleeve 3 into the connector 2.

[0046] A connecting component is used to connect and fix the cable tray body 1 and the connector 2.

[0047] In this embodiment, the cable tray body 1 is the basic unit constituting the cable tray system, and its length and cross-sectional dimensions can be customized according to actual wiring requirements. In practical applications, the cable tray body 1 can be made of extruded aluminum alloy profiles to provide good structural strength and corrosion resistance. As another implementation, the cable tray body 1 can also be formed by stamping and bending steel plates, and its surface can be galvanized or powder-coated to enhance protective performance. In addition, the cable tray body 1 can also be injection molded from high-strength engineering plastics to achieve lightweight and insulation performance.

[0048] Connector 2 is used to connect two sections of the cable tray body 1 that need to be connected. Connector 2 can be designed as a simple sleeve structure with an inner diameter slightly larger than the outer diameter of the cable tray body 1, connecting the two sections of the cable tray body 1 through an interference fit or adhesive bonding. Alternatively, connector 2 can be a U-shaped or C-shaped groove, with its internal space accommodating the connecting end of the cable tray body 1, and secured by external fasteners. For example, connector 2 can consist of two semi-circular or semi-rectangular housings, which are clamped to the outside of the connecting end of the cable tray body 1 by bolts.

[0049] A sealing sleeve 3 is fitted onto the connecting end of the two sections of the cable tray body 1 and pressed tightly within the connector 2 by the connecting end of the cable tray body 1 to achieve a waterproof function at the connection. The sealing sleeve 3 can be a simple annular gasket placed between the end face of the cable tray body 1 and the inner wall of the connector 2, achieving a seal through compression deformation. Alternatively, the sealing sleeve 3 can be an elastic sleeve with a certain thickness, its outer diameter fitting with the inner wall of the connector 2 and its inner diameter fitting with the outer wall of the cable tray body 1. When the cable tray body 1 is inserted into the connector 2, the sealing sleeve 3 is compressed, thus forming a seal. For example, the sealing sleeve 3 can be made of nitrile rubber, which has good oil resistance and aging resistance, and its cross-section can be designed as rectangular or circular to adapt to different connection interfaces.

[0050] During installation, the sealing sleeve 3 is placed on the two sections of the cable tray body 1 that need to be connected, and then the two sections of the cable tray body 1 are inserted into the two sections of the connector 2. The sealing sleeve 3 is squeezed by the cable tray body 1 and the connector 2 to form a sealing structure. At the same time, the cable tray body 1 and the connector 2 are connected and fixed by the connecting component, which can ensure the sealing of the connection and facilitate its disassembly and assembly.

[0051] As an optional implementation, both ends of the connector 2 are provided with slots 4, the end of the wire groove body 1 is inserted into the slot 4, and the sealing sleeve 3 is pressed into the slot 4.

[0052] In this embodiment, slots 4 are provided at both ends of connector 2. Slot 4 refers to a recessed structure formed inside connector 2 to accommodate the end of wire trough body 1, providing precise guidance and limiting for the insertion of wire trough body 1, thereby ensuring the alignment and stability of the connection. Slot 4 can be designed as a rectangular, U-shaped, or other irregularly shaped groove that matches the shape of the end of wire trough body 1. Its depth and width can be adjusted according to the size of wire trough body 1 and connection requirements to ensure that wire trough body 1 can be inserted securely. Sealing sleeve 3 is subjected to joint compression from the end of wire trough body 1 and the inner wall of slot 4 in the space of slot 4 inside connector 2, causing it to undergo elastic deformation, thereby forming a tight sealing contact. This ensures that sealing sleeve 3 can fully exert its waterproof function and effectively prevent moisture and dust from the external environment from entering the wire trough. Sealing sleeve 3 can be pre-placed at the bottom of slot 4, waiting to apply pressure to it when wire trough body 1 is inserted; or, sealing sleeve 3 can be sleeved on the end of wire trough body 1 and inserted into slot 4 together with wire trough body 1, and pressed tightly by the structure of slot 4 and the movement of wire trough body 1 during the insertion process.

[0053] During the insertion process, the end of the cable tray body 1 applies axial pressure to the sealing sleeve 3, while the inner wall of the slot 4 applies radial pressure to the sealing sleeve 3, effectively and evenly compressing the sealing sleeve 3 inside the connector 2. This compression method ensures that the sealing sleeve 3 fits tightly between the connector 2 and the cable tray body 1, forming a reliable waterproof barrier, thus solving the problem of uneven compression or poor sealing effect of the sealing sleeve 3 in traditional connection methods. At the same time, the guiding and limiting effect of the slot 4 on the cable tray body 1 also makes the connection between the two sections of the cable tray body 1 more stable and precise, enhancing the mechanical strength and stability of the connection.

[0054] As an optional implementation, the two slots 4 are spaced apart to form a heat dissipation channel 5, and the connector 2 is provided with heat dissipation holes 6 on the side wall of the heat dissipation channel 5.

[0055] In this embodiment, the slot 4 is a structure inside the connector 2 used to accommodate the end of the wire groove body 1. When there is a certain distance between two slots 4, this distance forms a space, namely a heat dissipation channel 5. The main function of the heat dissipation channel 5 is to provide an airflow path, allowing the heat accumulated inside the connector 2 to be dissipated to the external environment through convection or conduction. The heat dissipation channel 5 can be achieved by leaving a certain gap between the inner walls of the two slots 4 during the design of the connector 2, forming a through channel; or by setting a partition or support structure on the connector 2 body, so that the slots 4 naturally form a gap during installation, thereby forming a heat dissipation channel 5 between the partition or support structure. The heat dissipation hole 6 is an opening provided on the outer wall of the connector 2, connected to the internal heat dissipation channel 5. The heat dissipation hole 6 is the portal for heat exchange between the heat dissipation channel 5 and the external environment. It allows hot air to be discharged from the inside of the connector 2 and allows cold air to enter, thereby enhancing the heat dissipation effect. The heat dissipation holes 6 can be designed in various geometric shapes such as round, square or rectangular, and evenly distributed on the side wall of the connector 2 to maximize the heat dissipation area and efficiency; or they can be designed as a grid or mesh structure to ensure heat dissipation while also providing a certain degree of protection to prevent foreign objects from entering.

[0056] When the cable inside the cable tray body 1 is energized and generates heat, this heat is conducted through the walls of the cable tray body 1 and connector 2 to the internal space of connector 2. Due to the presence of the heat dissipation channel 5, the heat can effectively accumulate and flow along the channel. Simultaneously, the heat dissipation holes 6 located on the side wall of the heat dissipation channel 5 on connector 2 provide a path for the internal hot air to escape to the external environment and allow relatively cool external air to enter, forming an effective air convection circulation. This design enables connector 2 to actively manage heat while maintaining its connection and waterproof functions, avoiding localized heat accumulation in the connection area, thereby ensuring the long-term stable operation of the cable at the connection point and protecting the performance of critical components such as the sealing sleeve 3.

[0057] As an optional implementation, sealing ribs 7 are provided on both sides of the sealing sleeve 3, and the sealing ribs 7 abut against the groove walls on both sides of the slot 4.

[0058] In this embodiment, the sealing sleeve 3 is an elastic member used to form a seal between the connector 2 and the cable tray body 1. It can be made of various materials with good elasticity and weather resistance, such as nitrile rubber, silicone rubber, or EPDM rubber. The sealing ribs 7 are protrusions provided on the side wall of the sealing sleeve 3, which increase the contact pressure and sealing path between the sealing sleeve 3 and the groove wall of the slot 4. These ribs can be continuous annular structures or multiple intermittent circumferentially distributed protrusions. Their cross-sectional shape can be designed as semi-circular, rectangular, or trapezoidal to adapt to different sealing requirements and compression characteristics. The sealing ribs 7 abut against the groove walls on both sides of the slot 4, meaning that when the cable tray body 1 is inserted into the slot 4, the sealing ribs 7 will be subjected to radial compressive force from the inner wall of the slot 4, thereby providing an additional radial sealing effect in addition to the axial compression of the sealing sleeve 3.

[0059] When the end of the cable tray body 1 is inserted into the slot 4 of the connector 2, the cable tray body 1 not only applies axial pressure to the sealing sleeve 3, pressing it tightly at the bottom of the slot 4, but also the sealing ribs 7 on both sides of the sealing sleeve 3 are radially compressed due to the restriction of the inner wall of the slot 4, tightly fitting against the groove walls on both sides of the slot 4. This dual-directional compression sealing mechanism allows the sealing sleeve 3 to achieve more stable positioning and more comprehensive sealing contact within the slot 4. The presence of the sealing ribs 7 increases the tortuosity of the sealing path, improves the resistance to liquid penetration, and effectively compensates for minor gaps caused by manufacturing tolerances or thermal expansion and contraction, thereby ensuring that the connection maintains excellent waterproof performance under various operating conditions.

[0060] As an optional implementation, the sealing sleeve 3 is provided with an annular baffle 8 on the side wall inside the cable tray body 1, and the baffle 8 is attached to the end of the inner wall of the slot 4.

[0061] In this embodiment, when the cable tray body 1 is fully inserted, the annular stop 8 will fit tightly against the end of the inner wall of the slot 4. This structural design causes the sealing sleeve 3 to be subjected to radial compression within the slot 4. The fit between the annular stop 8 and the end of the inner wall of the slot 4 effectively prevents the sealing sleeve 3 from displacing axially. Even if the cable tray body 1 is subjected to axial pushing or pulling forces or vibrations, the sealing sleeve 3 can maintain its preset sealing position. Through this combination of radial sealing and axial limiting, the stability of the sealing sleeve 3 within the connector 2 and the reliability of the seal are ensured.

[0062] As an optional implementation, the connection component includes:

[0063] Connecting lugs 9 are located on both sides of the connecting end of the cable tray body 1;

[0064] Connecting plates 10 are disposed at both ends of connector 2 and correspond one-to-one with connecting lugs 9 on the two sections of the wire groove body 1;

[0065] Connector 11 is used to connect and fix the corresponding connecting lug 9 and connecting plate 10.

[0066] In this embodiment, the connecting components can be implemented in various forms, such as by using mechanical fasteners like bolts, rivets, and clips, or by welding, bonding, etc., to form a fixed connection. The connecting lugs 9 are protruding structures or extensions located on both sides of the connecting end of the cable tray body 1. Their main function is to serve as the force-bearing and positioning points for the connector 11 in the connecting components, providing a reliable attachment interface for fixing the cable tray body 1 and the connector 2. The connecting lugs 9 can be integrally formed with the cable tray body 1, or they can be attached to the cable tray body 1 by welding, riveting, or bolting. Their shape can be sheet-like, block-like, or a structure with holes. The connecting plate 10 is a plate-like structure located at both ends of the connector 2. Its function is to cooperate with the connecting lugs 9 on the cable tray body 1 to jointly form the fixing interface of the connecting components.

[0067] The connecting plate 10 can be integrally formed with the connector 2, or it can be fixed to the connector 2 by welding, bolting, or other methods. The connecting plate 10 typically has holes or slots for the connector 11 to pass through. The connector 11 is the specific physical element used to connect and fix the corresponding connecting lug 9 and the connecting plate 10. The selection of the connector 11 depends on factors such as the required connection strength, ease of disassembly, and cost. Common connectors 11 include bolts and nuts, rivets, pins, self-tapping screws, or clips. These connectors 11 achieve a reliable connection between the two by passing through the corresponding holes or slots on the connecting lug 9 and the connecting plate 10 and being tightened.

[0068] The connecting lugs 9 and the connecting plate 10 provide additional stress points and support surfaces, dispersing external forces and effectively limiting the relative movement between the cable tray body 1 and the connector 2. This significantly improves the tensile, bending, and vibration resistance of the entire waterproof cable tray connection. This multi-fixing method ensures that the cable tray body 1 and the connector 2 maintain a stable connection during long-term use, especially in harsh environments or under dynamic loads, thereby guaranteeing the safety of the cables inside the cable tray and the durability of its waterproof performance.

[0069] In one specific implementation, the connecting lug 9 can be designed as a flat, sheet-like structure extending outward from the side wall of the connecting end of the cable tray body 1, with a pre-drilled through hole. The connecting plate 10 can be designed as a plate-like structure extending outward from the end of the connector 2, also with a pre-drilled through hole corresponding to the position of the through hole in the connecting lug 9. The connector 11 can be a combination of standard bolts and nuts. During assembly, the connecting end of the cable tray body 1 is inserted into the connector 2, aligning the connecting lug 9 with the connecting plate 10. Then, the bolts are passed through the through holes on the connecting lug 9 and the connecting plate 10 in sequence, and the nuts are tightened on the other side. By tightening the nuts, the bolts tightly clamp the connecting lug 9 and the connecting plate 10 together, thereby achieving a secure connection between the cable tray body 1 and the connector 2. In addition, the contact surfaces of the connecting lug 9 and the connecting plate 10 can be designed with anti-slip textures or locating pins to further improve the resistance to rotation and shearing of the connection.

[0070] As an optional implementation, the connector 11 is a round-headed square-neck bolt. The connecting plate 10 is provided with a square hole 13 for engaging with the round-headed square-neck bolt. The connecting lug 9 is provided with a connecting hole 14, which is elongated. The round-headed square-neck bolt passes through the square hole 13 and the connecting hole 14, and engages with the nut to connect and fix the connecting lug 9 and the connecting plate 10.

[0071] In this embodiment, the round-head square-neck bolt is a fastener with a round head and a square neck. The round head typically provides a larger bearing area, while the square neck is designed to mate with a correspondingly shaped hole to prevent the bolt from rotating during tightening. This type of bolt can be made of various materials, such as carbon steel, stainless steel, or alloy steel, and can undergo surface treatments, such as galvanizing or nickel plating, to enhance its corrosion resistance, depending on the application environment. The square hole 13 is a hole provided on the connecting plate 10 that mates with the square neck of the round-head square-neck bolt. The size and shape of the square hole 13 precisely match the square neck of the bolt, and its main function is to prevent bolt rotation by engaging with the square neck when the bolt passes through and is tightened. The square hole 13 can be formed on the connecting plate 10 by methods such as stamping, milling, or laser cutting, and its precision directly affects the bolt's anti-rotation effect.

[0072] The connecting hole 14 is a slot provided on the connecting lug 9 for a round-headed square-neck bolt to pass through, characterized by its elongated shape. The main purpose of this elongated design is to provide a certain adjustment margin to compensate for dimensional tolerances or positional deviations that may exist between the cable tray body 1 and the connector 2 during manufacturing or installation. Through the elongated connecting hole 14, the relative position of the connecting lug 9 and the connecting plate 10 can be adjusted within a certain range, thus facilitating bolt insertion and alignment. The elongated connecting hole 14 can take various shapes such as elliptical, racetrack-shaped, or rectangular, and its length and width can be designed according to actual tolerance requirements. The nut is a fastener used in conjunction with the round-headed square-neck bolt. After the bolt passes through the connecting lug 9 and the connecting plate 10, tightening the nut applies a preload to the connector 11, thereby firmly connecting the connecting lug 9 and the connecting plate 10 together. The type of nut can include hexagonal nuts, flange nuts, self-locking nuts, etc., and its material is usually matched to the bolt to ensure the strength and reliability of the connection.

[0073] As an optional implementation, the cable tray body 1 is provided with a cable outlet 15, a cover plate 16 is provided on the cable outlet 15, and a cable outlet box assembly is provided on the cover plate 16. The cable outlet box assembly includes:

[0074] Mounting plate 17 is disposed on cover plate 16;

[0075] The cable outlet housing 18 is mounted on the mounting plate 17.

[0076] In this embodiment, the cable outlet 15 provided on the cable tray body 1 is an opening for cables to be led out from inside the cable tray body 1. The cable outlet 15 can be prefabricated as a rectangular, circular, or elliptical hole, or it can be a weak area formed by a stamping process that is easy to disassemble, or a replaceable opening achieved through modular design. Its function is to provide a pre-defined, controlled channel for the cable to exit. The cover plate 16 provided on the cable outlet 15 is a plate-like structure covering the cable outlet 15. The cover plate 16 can be made of materials such as metal or engineering plastics, and is fixed to the surface of the cable tray body 1 around the cable outlet 15 by bolts, rivets, clips, or welding. The main function of the cover plate 16 is to close the cable outlet 15 when cable exit is not required, protecting the cables inside the cable tray body 1 from external environmental influences, and to serve as a mounting base for the cable outlet box assembly when cable exit is required.

[0077] The cable outlet box assembly can be a prefabricated, one-piece structure or a modular unit assembled from multiple components. Its function is to provide additional physical protection, organization space, and possible sealing for cables leading out from the cable tray body 1, ensuring the safety of the cables after exiting and the waterproofness of the system. The cable outlet box assembly includes a mounting plate 17, which is disposed on the cover plate 16. The mounting plate 17 is the interface connecting the cable outlet box assembly and the cover plate 16; it can be integrally formed with the cover plate 16 or securely fixed to the cover plate 16 by screws, rivets, welding, etc. The mounting plate 17 provides a stable mounting base for the cable outlet housing 18, ensuring that the cable outlet box assembly can be reliably installed on the cover plate 16. The cable outlet housing 18, disposed on the mounting plate 17, is the main body of the cable outlet box assembly. The cable outlet housing 18 is typically a box-shaped structure with a certain volume, which can be made of materials such as plastic or metal, and its internal space is used to accommodate and protect the cables leading out from the cable tray body 1. The cable outlet housing 18 can be integrally formed with the mounting plate 17, or it can be detachably connected to the mounting plate 17 by means of clips, screws, etc. Its function is to provide a closed or semi-closed protective space for the outgoing cable to prevent the cable from being affected by external factors such as mechanical damage, dust, and moisture.

[0078] As an optional implementation, the outlet box assembly also includes an extended shell 19, which is slidably inserted into the outlet shell 18. The two side walls of the outlet shell 18 are provided with elongated grooves 20, and locking bolts 21 are provided in the grooves 20. The locking bolts 21 pass through the grooves 20 and the extended shell 19 and cooperate with nuts to fix the extended shell 19.

[0079] In this embodiment, the extended shell 19 is an adjustable part of the outlet box assembly, whose main function is to expand the internal space of the outlet box or adjust its external height. The extended shell 19 can be a hollow structural component with a specific cross-sectional shape, such as a rectangular or square cylinder, whose dimensions match the internal or external dimensions of the outlet shell 18 for sliding fit. Its material is typically the same as the outlet shell 18, such as metal or engineering plastic, to ensure structural strength and weather resistance. The extended shell 19 is connected and fitted to the outlet shell 18 via a sliding mechanism, allowing the extended shell 19 to extend or adjust relative to the outlet shell 18 in a specific direction (typically perpendicular to the cover plate 16). This sliding insertion can be achieved, but is not limited to: providing guide ribs on the outer or inner wall of the extended shell 19 to engage with guide grooves on the inner or outer wall of the outlet shell 18; or, using a clearance fit between the extended shell 19 and the outlet shell 18, guided by an external limiting structure. This design allows the effective depth or height of the outlet box assembly to be adjusted steplessly or in stages according to actual needs.

[0080] Elongated grooves 20 are provided on both side walls of the outlet housing 18. Their function is to provide a movable fixing path for the locking bolts 21, thereby allowing the extended housing 19 to slide within a certain range. The grooves 20 typically extend along the sliding direction of the extended housing 19, and their length determines the maximum adjustment range of the extended housing 19. The width of the grooves 20 should be slightly larger than the diameter of the shank of the locking bolts 21 to ensure smooth sliding of the bolts, while not being too wide to prevent wobbling during fixing. The locking bolts 21 pass through the grooves 20 and the extended housing 19, and engage with the nut to generate clamping force, thereby reliably fixing the extended housing 19. When the extended housing 19 is adjusted to the desired position, the locking bolts 21 will pass through the elongated grooves 20 on the side walls of the outlet housing 18 and the corresponding through holes on the extended housing 19. Subsequently, the nut is tightened onto the threaded end of the locking bolt 21. Through the self-locking action of the thread and the clamping force between the nut and the extended housing 19 and the cable outlet housing 18, the extended housing 19 is securely fixed in its current position. This fixing method is simple, reliable, and easy to operate, and can be adjusted and re-fixed multiple times as needed. The locking bolt 21 can be loosened, and then the extended housing 19 can be pushed or pulled along the slide groove 20 to reach the desired position. Once the extended housing 19 is in place, the locking bolt 21 passes through the corresponding hole in the slide groove 20 and the extended housing 19, and tightens with the nut. The clamping force generated by the bolt and nut secures the extended housing 19 to the cable outlet housing 18, preventing accidental movement. This design makes the overall size of the cable outlet assembly adjustable, flexibly adapting to different wiring spaces and cable volumes without replacing the entire cable outlet assembly, thus improving product versatility and ease of installation.

[0081] As an optional implementation, a sealing gasket 12 is provided around the outlet 15 on the cable tray body 1, and the cover plate 16 presses the sealing gasket 12 tightly onto the cable tray body 1.

[0082] In this embodiment, the sealing gasket 12 is typically made of a material with good elasticity and weather resistance, such as rubber, silicone, polyurethane, or foam. The function of the sealing gasket 12 is to provide a compressible barrier that, when subjected to pressure, deforms and tightly adheres to the contact surface, thereby forming an effective seal. "Enclosed around the outlet 15" means that the sealing gasket 12 is arranged around the outlet 15, forming a closed annular area. This annular arrangement ensures that the entire perimeter between the outlet 15 and the cover plate 16 is effectively sealed, preventing external environmental factors from intruding from any direction. For example, the sealing gasket 12 can be pre-formed into an annular structure matching the shape of the outlet 15, or formed by attaching or embedding strip-shaped sealing material along the edge of the outlet 15 to form an annular shape. The cover plate 16 presses the sealing gasket 12 tightly, causing the sealing gasket 12 to elastically deform, thereby filling the small gaps and irregular surfaces between the cover plate 16 and the cable tray body 1, forming a continuous and tight sealing barrier. For example, the cover plate 16 can be fixed to the groove body 1 by screws, and the tightening force of the screws will press the cover plate 16 downward, thereby pressing the sealing gasket 12; or, the cover plate 16 can be designed with a snap-fit ​​structure, which will fix the cover plate 16 and press the sealing gasket 12 by the elastic deformation of the snap-fit.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
