Description

Technical Field

[0001] This utility model relates to the field of power equipment, specifically to a line protection structure and its air source heat pump water heater. Background Technology

[0002] Air source heat pump water heaters, as energy-saving and environmentally friendly hot water supply devices, produce domestic hot water by absorbing heat from the air and are widely used in hotels, swimming pools, factories, and other places. These units require extensive wiring. Existing technologies typically use sheet metal through-holes with rubber rings to allow cables to pass through, supplemented by metal wire clamps for cable fixation. For example, patent application CN103036181A discloses a through-hole including a wire guide coil, a frame, and a through-hole in the middle of the frame. A soft seal is installed on the through-hole, functioning similarly to a rubber ring. This soft seal penetrates the through-hole, protecting the wiring inside the electrical box. However, this design has certain problems. First, installing the soft seal on the frame through-hole is cumbersome. Second, the metal wire clamps used in existing technologies are prone to slippage, causing the soft seal to be pulled away from the through-hole when the cable is dragged, resulting in the cable directly rubbing against the edge of the sheet metal through-hole, posing a safety hazard of damaging the insulation layer. Utility Model Content

[0003] The present invention aims to provide a cable protection structure that prevents cables from slipping and is easy to install.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cable guide structure, including cable ties, a mounting plate, and a protective shell detachably mounted on the mounting plate. The mounting plate has a protective shell slot for the protective shell to pass through. The protective shell has a cable through hole for cable passage. The cable through hole is a cable inlet on the top side of the protective shell and a cable outlet on the bottom side. The top circumference of the protective shell has a mounting wall with its outer edge protruding relative to the outer edge of the protective shell. The mounting wall can be engaged with the protective shell slot. At least one cable separator for separating different cables is arranged inside the cable through hole. Several cable bundles are arrayed at the cable outlet end of the protective shell. Each cable bundle has multiple cable bundle holes for cable ties to pass through.

[0005] The beneficial effects of this plan are:

[0006] The protective shell and mounting bracket are detachably mounted on the mounting plate. The outer edge of the mounting bracket protrudes relative to the outer edge of the protective shell and engages with the gap in the protective shell, preventing the protective shell from detaching from the mounting plate when the cable is dragged. This ensures the long-term stability of cable protection and provides a more secure locking effect. The detachable nature of the protective shell improves the convenience of its installation and maintenance.

[0007] The installation of cable dividers can effectively isolate cables with different functions, making the wiring neat and beautiful, avoiding tangling or friction between different types of cables, improving the neatness of cable wiring, reducing the possibility of insulation wear, extending the service life of cables, and facilitating subsequent maintenance and inspection.

[0008] The bottom of the protective casing features a series of cable management panels, each with multiple holes for cable ties to pass through and secure the cables. The cables are then firmly bundled and categorized and fixed to the cable management panels using the cable ties, ensuring greater stability and preventing movement due to external forces. This overall design fully considers cable protection needs, significantly reducing the possibility of insulation damage or tearing, and is suitable for wiring requirements in various scenarios.

[0009] Preferably, as an improvement, there are two dividing partitions, and the cable holes are sequentially divided into user wiring channels, high-voltage channels inside the unit, and low-voltage channels inside the unit through the dividing partitions.

[0010] The beneficial effects are as follows: by setting multiple cable dividers, the cable holes are divided into user wiring channels, high-voltage channels and low-voltage channels. The cable dividers help separate high-voltage and low-voltage cables, prevent the lines from being mixed, improve the neatness of the wiring, and reduce the difficulties in subsequent maintenance caused by messy wiring.

[0011] Preferably, as an improvement, the number of cable trays is at least four, with two of them located at the two ends of the bottom of the protective shell, and the remaining two located at the bottom of the cable divider.

[0012] The benefits include: the cable management plate at the bottom of the protective case can securely bundle the cables at the exit of the protective case, preventing the cables from slipping or loosening due to dragging. Multiple cable management plates can be used to bundle different numbers or specifications of cables, providing flexible fixing options.

[0013] Preferably, as an improvement, it also includes a conductor board for routing the cable, the conductor board including a conductor substrate, the upper surface of the conductor substrate being connected to the bottom surface of the cable tray, and a bent edge provided on one side in the width direction of the conductor board, and the conductor board and the bent edge being connected and transitioned by an arc.

[0014] The beneficial effects are as follows: With the above settings, when the cable passes through the top of the protective shell and exits through the top of the protective shell and passes through the cable tray, the cable passes around the bent side of the conductor plate and exits. The conductor plate guides the cable that exits the protective shell. The connection between the first plate and the second plate is rounded to avoid the cable rubbing and damaging the outer rubber of the cable at the corner during the process of pulling the cable.

[0015] Preferably, as an improvement, the protective shell has multiple slots circumferentially arranged in the missing area, and the lower surface of the mounting wall has buckles that can engage with the slots, the number of buckles being the same as the number of slots.

[0016] The beneficial effects are: by setting the slots and buckles, the connection stability between the mounting bracket and the mounting plate is improved, while the installation is quick and efficient. At the same time, it can be quickly disassembled during maintenance or repair, saving time.

[0017] Preferably, as an improvement, the inner edge of the mounting wall is provided with a stepped groove, and a flexible rubber cloth is embedded in the stepped groove. The flexible rubber cloth has linear wire holes.

[0018] The beneficial effects are as follows: by embedding flexible rubber cloth and linear cable passage holes in the stepped groove, the rubber cloth is elastic, allowing the cable to pass through the linear cable passage holes and through the protective shell. At the same time, the flexible rubber cloth can also play a role in shielding and separating, forming a flexible barrier to prevent dust and moisture from entering.

[0019] An air source heat pump water heater includes a unit body, inside which is a control box. Either side panel of the control box serves as a mounting plate, and a protective shell passes through and is detachably connected to a slot in the protective shell. Attached Figure Description

[0025] The following detailed description is provided through specific implementation methods and examples:

[0026] The preferred embodiments of this utility model are basically as shown in the appendix. Figure 1-4 As shown, Figure 1 and Figure 2The cable protection structure shown includes cable ties, a mounting plate 1, and a protective shell 2 detachably mounted on the mounting plate 1. The mounting plate 1 has a protective shell slot 13 for the protective shell 2 to pass through. The protective shell 2 has a cable inlet at the top and a cable outlet at the bottom. A mounting wall 3 is provided around the top circumference of the protective shell 2, with its outer edge protruding relative to the outer edge of the protective shell 2. The mounting wall 3 can engage with the protective shell slot 13. The protective shell 2 has a cable passage hole, and at least one cable divider 4 is arranged within the cable passage hole to separate different cables. To ensure a simple and reliable structure, the preferred embodiment of this invention uses two cable dividers 4. The cable passage hole is sequentially divided by the cable dividers 4 into a user wiring channel 5, a high-voltage channel 6 within the unit, and a low-voltage channel 7 within the unit. The cable dividers 4 assist in the separation of high-voltage and low-voltage cables, preventing cable mixing and improving wiring neatness while reducing subsequent maintenance difficulties caused by messy wiring. The cable ties are UV-resistant and high-temperature resistant. The installation of the cable divider 4 can effectively isolate cables with different functions, making the wiring neat and beautiful, avoiding tangling or friction between different types of cables, improving the neatness of the cable wiring, reducing the possibility of insulation wear, extending the service life of the cables, and facilitating subsequent maintenance and inspection.

[0027] The protective shell 2 and the mounting wall 3 are detachably installed on the mounting plate 1. The outer edge of the mounting wall 3 protrudes relative to the outer edge of the protective shell 2 and engages with the gap 13 of the protective shell, preventing the protective shell 2 from detaching from the mounting plate 1 when the cable is dragged, thereby ensuring the long-term stability of cable protection and providing a more secure locking effect. The detachability of the protective shell 2 can improve the convenience of installation and maintenance of the protective shell 2.

[0028] like Figure 2 and Figure 3 As shown, the cable outlet array of the protective shell 2 is provided with several cable bundling plates 8. Each cable bundling plate 8 has multiple cable bundling holes 9 for cable ties to pass through. To ensure a simple and reliable structure, the preferred embodiment of this invention uses at least four cable bundling plates 8, two of which are fixedly installed at both ends of the bottom of the protective shell 2, and the remaining two are installed at the bottom of the cable divider 4. The cable bundling plates 8 are arrayed at the bottom of the protective shell 2, and each cable bundling plate 8 has multiple cable bundling holes 9 for cable ties to pass through and fix. Through the cooperation of the cable ties and the cable bundling holes 9, the cables are firmly bundled and classified and fixed on the cable bundling plates 8, making the cables more stable after fixing and preventing them from moving due to external forces. The overall structure of this technical solution fully considers the protection needs of the cables, greatly reducing the possibility of the insulation layer being scratched or damaged, and is suitable for wiring needs in various scenarios.

[0029] To ensure a simple and reliable structure, the preferred embodiment of this invention further includes a conductor plate 10 for guiding the cable. The conductor plate 10 includes a conductor substrate, the upper surface of which is connected to the bottom surface of the cable tray 8. A bent edge is provided on one side of the conductor plate in the width direction, and the conductor plate and the bent edge are connected by an arc. When the cable enters and exits from the top of the protective shell 2 and passes through the cable tray 8, the cable bypasses the bent edge of the conductor plate and exits. The conductor plate 10 guides the cable exiting the protective shell 2. The connection between the first plate and the second plate is rounded to prevent friction damage to the cable's outer sheath at the corner during cable pulling.

[0030] To ensure a simple and reliable structure, the preferred embodiment of this invention features multiple slots circumferentially arranged in the protective shell cavity 13, and buckles 11 on the lower surface of the mounting wall 3 that engage with the slots. The number of buckles 11 is the same as the number of slots. The slots and buckles 11 enhance the connection stability between the mounting wall 3 and the mounting plate 1, while also allowing for quick installation and improved efficiency. Furthermore, they enable rapid disassembly during maintenance or repair, saving time. To achieve dustproof cable storage, the preferred embodiment of this invention features a stepped groove 12 on the inner edge of the mounting wall 3. A flexible rubber sheet is embedded in the stepped groove 12, and linear cable passage holes are formed on the flexible rubber sheet. By embedding the flexible rubber sheet and the linear cable passage holes in the stepped groove 12, the rubber sheet's elasticity allows the cable to pass through the linear cable passage holes and through the protective shell 2. Simultaneously, the flexible rubber sheet also acts as a shield and barrier, forming a flexible barrier to prevent dust and moisture from entering.

[0031] like Figure 4 As shown, the air source heat pump water heater includes a unit body 14, a control box 15 is provided inside the unit body 14, and any side panel of the control box 15 is a mounting plate 1. The protective shell 2 passes through and is detachably connected to the protective shell slot 13.
