Description

Technical Field

[0001] This invention relates to the technical field of wiring brackets in air conditioner outdoor units, and more particularly to a wiring bracket and an air conditioner outdoor unit formed therefrom. Background Technology

[0002] The indoor and outdoor units of an air conditioner need to be connected and controlled via signal cables. These signal cables extend from the indoor unit and connect to a terminal block on the outdoor unit. This terminal block is typically mounted on the right side panel of the outdoor unit and is used to connect the signal cables in the indoor unit to the electrical box in the outdoor unit. In existing technology, the terminal block is directly fixed to the right side panel.

[0003] Air conditioner outdoor units are installed outdoors and are prone to rust and corrosion after being exposed to water during rainy days. Therefore, the outer surface of the outdoor unit's panel is coated with a waterproof coating. During actual wiring, the electrical box and signal lines need to be grounded. However, because the right side panel of the outdoor unit has a coating, the electrical box and signal lines need to be grounded through this coated panel. The grounding screw, fixed within the coating, cannot provide a proper grounding effect, and the grounding indicator is not clearly visible after the coating, thus failing to serve its intended purpose. Summary of the Invention

[0004] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a wiring bracket that grounds the ground wire using fasteners made of conductive material, ensuring a good grounding effect, avoiding the poor grounding phenomenon caused by the coating in the prior art, and improving the wiring stability of the wiring board.

[0005] A terminal bracket is used to fix a terminal block and ground the ground wire inside the terminal block; the terminal bracket includes a grounding area and a fixing area for fixing the terminal block, the grounding area is provided with a grounding hole, and the ground wire in the terminal block is fixed in the grounding hole by a conductive fastener.

[0006] In a preferred embodiment of the present invention, the fastener includes a grounding nut and a grounding screw, wherein the grounding nut is embedded inside the grounding hole; and the grounding screw fixes the ground wire in the internal threaded hole of the grounding nut.

[0007] The grounding nut is fixed inside the wiring hole. The grounding nut has an internal threaded hole, and the external thread of the grounding screw matches the internal threaded hole. Here, the ground wire refers to the signal wire or the ground wire in the electrical box. The ground wire is fixed in the internal threaded hole by the grounding screw. The ground wire, grounding screw, and grounding nut are all conductive, and the grounding hole is directly grounded, thus achieving a good grounding effect. In this application, the fixing plate does not require painting. The grounding screw and grounding nut are all conductive, ensuring a good grounding effect. At the same time, the matching of the grounding screw and grounding nut ensures the stability of the connection between the ground wire and the grounding hole.

[0008] In a preferred embodiment of the present invention, the grounding hole is hexagonal, and the inner diameter of the grounding hole is equal to the outer diameter of the grounding nut.

[0009] The grounding hole is designed with the same hexagonal structure as the grounding nut, and the grounding nut can be fixed inside the grounding hole by welding or other means to ensure the stability of the connection between the grounding nut and the grounding hole and to avoid the grounding wire misalignment or displacement when grounding the ground wire.

[0010] In a preferred embodiment of the present invention, a first fixing through hole is provided in the fixing area, and the wiring board is fixed in the first fixing through hole.

[0011] In actual operation, the fixing area and the wiring area are respectively set on the left and right sides. The fixing area is used to fix the wiring board, and the wiring area is equipped with plug-in positions. Two signal lines, two electrical boxes, or one signal line and one electrical box are connected at the plug-in positions to achieve signal communication. The wiring board is fixed inside the first through hole by screws or other fasteners. This application fixes the wiring board, ensuring that its position is fixed and avoiding the defect of unstable wiring caused by the wiring board shaking during the movement of the panel or the whole machine.

[0012] In a preferred embodiment of the present invention, the terminal block is provided with a first signal line and a second signal line that are plugged into each other, and a magnetic ring is provided in the first signal line or the second signal line.

[0013] The wiring bracket includes a fixing plate, the contact area and the fixing area are located inside the fixing plate, and the top of the fixing plate is connected to a limiting plate for limiting the magnetic ring.

[0014] In this application, the contact area and the fixing area are integrated into a fixing plate. The fixing plate has a planar plate structure, and the contact area and the fixing area are distributed left and right within the fixing plate, i.e., the contact area is on the left and the fixing area is on the right. A limit plate is connected to the top of the fixing plate to limit and fix the magnetic rings, preventing them from shaking and colliding with each other during the movement of the entire device, which would affect the normal use and performance of the magnetic rings. The magnetic rings are positioned outside the first signal line or the second signal line to provide an anti-interference effect.

[0015] In a preferred embodiment of the present invention, the limiting plate includes a second fixing through hole, and the magnetic ring is fixed in the second fixing through hole by a binding wire.

[0016] To limit and fix the magnetic ring, a second fixing through hole is provided in the limiting plate. When the magnetic ring is blocked outside the limiting plate, it is fixed inside the second fixing through hole by a binding wire. Specifically, the binding wire is made of insulated wire, and the magnetic ring is a hollow ring structure that is sleeved on the outside of the signal line. The binding wire passes through the hollow ring of the magnetic ring, through the edge of the limiting plate, and out of the second fixing through hole for tightening, thereby fixing the magnetic ring in the limiting plate. This application achieves the fixing of the magnetic ring through the cooperation of the second fixing through hole and the binding wire. The structure is simple, the operation is convenient, and it can achieve stable limiting of the magnetic ring, preventing damage caused by the magnetic ring shaking or contact.

[0017] In a preferred embodiment of the present invention, the plane on which the limiting plate is located is a horizontal plane, and the bending angle between the limiting plate and the fixing plate is greater than 90°.

[0018] This application uses a horizontal limiting plate to support the weight of the magnetic ring after it is fixed. If the limiting plate were an inclined plate structure, it would be unable to support the magnetic ring vertically, and the magnetic ring might break free from the binding wire under gravity, making stable positioning impossible. Simultaneously, setting the fixing plate as an inclined plate facilitates the fixing operation of the wiring board.

[0019] In a preferred embodiment of the present invention, the edges of the limiting plate and the fixing plate are folded edges.

[0020] The folded edge structure refers to the fact that the limiting plate and the fixing plate are folded towards the side away from the fixed terminal block, forming a folded edge structure. The folded edge structure ensures that the terminal block has good strength, and at the same time, it makes the edges of the terminal block smooth, preventing the sharp edges of the terminal block from scratching the signal lines or wires in the electrical box when assembling with the terminal block, signal lines, or electrical boxes.

[0021] In a preferred embodiment of the present invention, the wiring bracket includes a fixing plate, the connection area and the fixing area are located inside the fixing plate, the bottom of the fixing plate is connected to a mounting plate, the mounting plate is provided with a third fixing through hole, and the wiring bracket is fixed inside the panel through the third fixing through hole.

[0022] This application features a limiting plate at the top of the fixing plate for limiting and fixing the magnetic ring; and a mounting plate at the bottom of the fixing plate for mounting the wiring bracket entirely inside the panel. The mounting plate has a third fixing through hole through which screws and other fasteners are used to directly mount the wiring bracket entirely inside the panel. The bending angle between the mounting plate and the fixing plate can be specifically set according to the structure and position of the panel, ensuring easy assembly of the mounting plate and the panel.

[0023] The second objective of this application is to provide an outdoor unit for an air conditioner, including a wiring bracket as described above. The signal lines in the indoor unit and the electrical box in the outdoor unit need to be connected to a junction box, which needs to be fixed inside the outdoor unit. This application grounds the signal lines and the ground wire in the electrical box through a grounding hole in the wiring bracket, ensuring a good grounding effect, avoiding poor grounding caused by the coating on the panel, and improving the performance stability of the signal lines and the electrical box.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention provides a wiring bracket for fixing a wiring board in a panel and grounding the ground wire within the wiring board. The wiring bracket includes a grounding area and a fixing area for fixing the wiring board. A grounding hole is provided in the grounding area, and the ground wire of the wiring board is fixed in the grounding hole by a conductive fastener. This application grounds the ground wire using a conductor-material fastener, ensuring a good grounding effect and avoiding the poor grounding phenomenon caused by the coating in the prior art, thus improving the wiring stability of the wiring board.

[0026] This application also provides an outdoor unit for an air conditioner, including the wiring bracket as described above. The signal line in the indoor unit and the electrical box in the outdoor unit need to be plugged into the wiring board. At the same time, the wiring board needs to be fixed inside the outdoor unit. This application grounds the signal line and the ground wire in the electrical box through the grounding hole in the wiring bracket, which can ensure a good grounding effect, avoid poor grounding caused by the coating on the panel, and improve the performance stability of the signal line and the electrical box.

[0038] Example 1

[0039] like Figures 1-5As shown, this application provides a wiring bracket for fixing a wiring board 42 and grounding the ground wire inside the wiring board 42; the wiring bracket includes a grounding area and a fixing area for fixing the wiring board 42, the grounding area is provided with a grounding hole 22, and the ground wire in the wiring board 42 is fixed in the grounding hole 22 by a fastener that can conduct electricity.

[0040] The junction box 42 of this application is provided with a plug-in position, which allows two signal lines or wires from two electrical boxes to be connected, enabling the two signal lines or two electrical boxes to conduct and transmit signals. The plug-in position can be used to plug in two signal lines, two electrical boxes, or a signal line and an electrical box.

[0041] The wiring bracket in this application can be used in an air conditioner outdoor unit. The outdoor unit contains an electrical box, and the wires in the electrical box need to be connected to the signal lines in the indoor unit to achieve unified control of both units. During wiring, the signal lines from the indoor unit and the electrical box are stretched to the junction box 42, where they are plugged in. The junction box 42 is fixed to the mounting area of ​​the wiring bracket, and the entire wiring bracket is then fixed to the panel 41 of the outdoor unit. In this way, the wiring bracket is built into the outdoor unit, with a certain distance between it and the outdoor unit's casing. A waterproof coating is applied to the outdoor unit's casing to shield and protect the wiring bracket from water contact.

[0042] In this application, both the signal lines and the electrical box are equipped with ground wires. Correspondingly, the grounding bracket needs to have at least two grounding holes 22 to ground the signal lines and the electrical box respectively. Preferably, the number of grounding holes 22 can be greater than two to prevent one of the grounding holes 22 from becoming blocked or deformed, thus extending the service life of the wiring bracket.

[0043] This application grounds the ground wire using fasteners made of conductive material, which ensures a good grounding effect, avoids the poor grounding phenomenon caused by the coating in the prior art, and improves the wiring stability of the terminal block 42.

[0044] Example 2

[0045] like Figures 1-5 As shown, this application provides a wiring bracket for fixing a wiring board 42 and grounding the ground wire inside the wiring board 42; the wiring bracket includes a grounding area and a fixing area for fixing the wiring board 42, the grounding area is provided with a grounding hole 22, and the ground wire in the wiring board 42 is fixed in the grounding hole 22 by a fastener that can conduct electricity.

[0046] Furthermore, the fastener includes a grounding nut and a grounding screw 25, the grounding nut being embedded inside the grounding hole 22; the grounding screw 25 fixing the ground wire inside the internal threaded hole of the grounding nut.

[0047] The grounding nut is fixed inside the wiring hole. The grounding nut has an internal threaded hole, and the external thread of the grounding screw 25 matches the internal threaded hole. Here, the ground wire refers to the signal wire or the ground wire in the electrical box. The ground wire is fixed in the internal threaded hole by the grounding screw 25. The ground wire, grounding screw 25, and grounding nut are all conductive, and the grounding hole 22 is directly grounded, thus achieving a good grounding effect. In this application, the fixing plate 21 does not require painting. The grounding screw 25 and grounding nut are both conductive, ensuring a good grounding effect. Simultaneously, the matching of the grounding screw 25 and grounding nut ensures the stable connection between the ground wire and the grounding hole 22.

[0048] Furthermore, the grounding hole 22 is hexagonal, and the inner diameter of the grounding hole 22 is equal to the outer diameter of the grounding nut.

[0049] The grounding hole 22 is set with the same hexagonal structure as the grounding nut, and the grounding nut can be fixed inside the grounding hole 22 by welding or other means to ensure the connection between the grounding nut and the grounding hole 22 is stable and to avoid the grounding wire misalignment or displacement when grounding the ground wire.

[0050] Furthermore, a first fixing through hole 24 is provided in the fixing area, and the wiring board 42 is fixed in the first fixing through hole 24.

[0051] In actual operation, the fixing area and the wiring area are respectively set on the left and right sides. The fixing area is used to fix the wiring board 42. The wiring area is provided with plug-in positions. Two signal lines, two electrical boxes, or one signal line and one electrical box are connected at the plug-in positions to realize signal communication. The wiring board 42 is fixed inside the first through hole by screws or other fasteners. This application fixes the wiring board 42 to ensure that the position of the wiring board 42 is fixed, avoiding the defect of unstable wiring caused by the shaking of the wiring board 42 during the movement of the panel 41 or the whole machine.

[0052] The number of first fixed through holes 24 can be specifically set according to the number of terminal blocks 42.

[0053] Furthermore, the terminal block 42 is provided with a first signal line and a second signal line that are plugged into each other, and a magnetic ring 43 is provided in the first signal line or the second signal line;

[0054] The wiring bracket includes a fixing plate 21, the connection area and the fixing area are located inside the fixing plate 21, and the top of the fixing plate 21 is connected to a limiting plate 11 for limiting the magnetic ring 43.

[0055] In this application, the contact area and the fixing area are integrated into a fixing plate 21. The fixing plate 21 has a flat plate 41 structure, and the contact area and the fixing area are distributed left and right within the fixing plate 21, i.e., the left side is the contact area and the right side is the fixing area. A limit plate 11 is connected and installed at the top of the fixing plate 21. The limit plate 11 is used to limit and fix the magnetic ring 43, preventing the magnetic ring 43 from shaking and colliding with each other during the movement of the whole machine, which would affect the normal use and performance of the magnetic ring 43. The magnetic ring 43 is located outside the first signal line or the second signal line, which has an anti-interference effect.

[0056] In actual operation, either the first or second signal line can be an electrical box. When the terminal block 42 is used to connect the signal line and the electrical box, only the outer side of the signal line is provided with a magnetic ring 43; the outer side of the electrical box does not need to be provided with a magnetic ring 43. In this case, the signal line passes through the limiting plate 11 and enters the terminal block 42 position inside the fixed plate 21. The magnetic ring 43 on the outer side of the signal line is blocked in the limiting plate 11. The limiting plate 11 can be provided with structures such as clips and through holes to limit and fix the magnetic ring 43. The wires in the electrical box do not need to pass through the limiting plate 11 and directly enter the terminal block 42 position inside the fixed plate 21.

[0057] When the terminal block 42 is used to connect two signal lines, namely the first signal line and the second signal line, if both the first signal line and the second signal line are provided with magnetic rings 43, the first signal line and the second signal line can pass through the limiting plate 11 and enter the two ends of the terminal block 42 inside the fixing plate 21 to realize the insertion of the first signal line and the second signal line in the terminal block 42. At the same time, the magnetic rings 43 are blocked in the limiting plate 11. The limiting plate 11 can be provided with structures such as buckles and through holes to limit and fix the magnetic rings 43.

[0058] Furthermore, the limiting plate 11 includes a second fixing through hole 12, and the magnetic ring 43 is fixed in the second fixing through hole 12 by a binding wire 44.

[0059] To limit and fix the magnetic ring 43, a second fixing through hole 12 is provided in the limiting plate 11. When the magnetic ring 43 is blocked outside the limiting plate 11, the magnetic ring 43 is fixed inside the second fixing through hole 12 by the binding wire 44. Specifically, the binding wire 44 is made of insulated wire, and the magnetic ring 43 is a hollow ring structure that is sleeved on the outside of the signal line. The binding wire 44 passes through the hollow ring of the magnetic ring 43, passes through the edge of the limiting plate 11 to the second fixing through hole 12 and is tightened to fix the magnetic ring 43 in the limiting plate 11. This application achieves the fixation of the magnetic ring 43 through the cooperation of the second fixing through hole 12 and the binding wire 44. The structure is simple, the operation is convenient, and it can achieve stable limiting of the magnetic ring 43, avoiding damage caused by the magnetic ring 43 shaking or touching.

[0060] The number of the second fixing through holes 12 can be specifically set according to the number of magnetic rings 43. At the same time, the second fixing through holes 12 need to be evenly distributed in the limiting plate 11 to avoid them being concentrated together and causing the magnetic rings 43 to touch each other.

[0061] Furthermore, the plane on which the limiting plate 11 is located is a horizontal plane, and the bending angle between the limiting plate 11 and the fixing plate 21 is greater than 90°.

[0062] The limiting plate 11 is set as a horizontal plate in this application so as to support the weight of the magnetic ring 43 after it is fixed. If the limiting plate 11 is an inclined plate structure, it cannot support the magnetic ring 43 in the vertical direction, and the magnetic ring 43 may break free from the binding wire 44 under the action of gravity, thus failing to achieve stable positioning of the magnetic ring 43. At the same time, setting the fixing plate 21 as an inclined plate facilitates the fixing operation of the wiring plate 42.

[0063] Furthermore, the edges of the limiting plate 11 and the fixing plate 21 are folded edges.

[0064] The folded edge structure refers to the fact that the limiting plate 11 and the fixing plate 21 are folded towards the side away from the fixing of the terminal block 42, forming a folded edge structure. The folded edge structure can ensure that the terminal block has good strength, and at the same time, it can also make the edge of the terminal block smooth, so as to prevent the sharp edge of the terminal block from scratching the signal line or the wire in the electrical box when it is assembled with the terminal block 42, signal line or electrical box.

[0065] Furthermore, the wiring bracket includes a fixing plate 21, the connection area and the fixing area are located within the fixing plate 21, the bottom of the fixing plate 21 is connected to a mounting plate 31, the mounting plate 31 is provided with a third fixing through hole 32, and the wiring bracket is fixed within the panel 41 through the third fixing through hole 32.

[0066] This application provides a limiting plate 11 at the top of the fixing plate 21 for limiting and fixing the magnetic ring 43; and a mounting plate 31 at the bottom of the fixing plate 21 for mounting the wiring bracket as a whole inside the panel 41. The mounting plate 31 has a third fixing through hole 32 through which screws and other fasteners are used to directly mount the wiring bracket as a whole inside the panel 41. The bending angle between the mounting plate 31 and the fixing plate 21 can be specifically set according to the structure and position of the panel 41, ensuring that the mounting plate 31 and the panel 41 can be easily assembled.

[0067] Example 3

[0068] This application provides a wiring bracket for fixing a terminal block 42 and grounding the ground wire inside the terminal block 42. The wiring bracket includes a limiting plate 11, a fixing plate 21, and a mounting plate 31, wherein the fixing plate 21 is located between the limiting plate 11 and the mounting plate 31, and the limiting plate 11, fixing plate 21, and mounting plate 31 are bent together. A limiting plate 11 is provided at the top of the fixing plate 21 for limiting and fixing the magnetic ring 43; a mounting plate 31 is provided at the bottom of the fixing plate 21 for mounting the wiring bracket as a whole inside the panel 41. The limiting plate 11, fixing plate 21, and mounting plate 31 are all made of hot-dip galvanized steel sheet Q235A 0.95X1150XC, which is not easy to rust and corrosion and has high strength. Figure 2 As shown, the fixing plate 21 is a vertical plate, and the limiting plate 11 and the mounting plate 31 are inclined plates extending in different directions.

[0069] In this embodiment, the junction box 42 is used to connect the signal line in the indoor unit of the air conditioner and the electrical box in the outdoor unit. A magnetic ring 43 is sleeved on the outside of the signal line.

[0070] The limiting plate 11 has a second fixing through hole 12, and the magnetic ring 43 is fixed in the second fixing through hole 12 by a binding wire 44. The signal line passes through the limiting plate 11 and enters the terminal block 42 position inside the fixing plate 21. The magnetic ring 43 on the outside of the signal line is blocked in the limiting plate 11. The limiting plate 11 has a second fixing through hole 12. The binding wire 44 is made of insulated wire. The magnetic ring 43 has a hollow ring structure and is sleeved on the outside of the signal line. The binding wire 44 passes through the hollow ring of the magnetic ring 43, passes through the edge of the limiting plate 11 to the second fixing through hole 12 and is tightened to fix the magnetic ring 43 in the limiting plate 11. The number of second fixing through holes 12 can be specifically set according to the number of magnetic rings 43. At the same time, the second fixing through holes 12 need to be evenly distributed in the limiting plate 11 to avoid them being concentrated together and causing the magnetic rings 43 to touch each other.

[0071] The fixing plate 21 includes a grounding area and a fixing area for fixing the terminal block 42. The fixing area and the terminal block are respectively located on the left and right sides of the fixing plate 21. A grounding hole 22 is provided in the grounding area. The grounding hole 22 is hexagonal, and the inner diameter of the grounding hole 22 is equal to the outer diameter of the grounding nut. The grounding nut is fixed inside the grounding hole 22. The grounding screw 25 fixes the ground wire to be grounded in the internal thread hole of the grounding nut. The ground wire to be grounded includes the ground wire in the signal line and the ground wire in the electrical box.

[0072] A first fixing through hole 24 is provided within the fixing area, and the terminal block 42 is fixed within the first fixing through hole 24. The first fixing through hole 24 is located in the center of the fixing area. The position of the first fixing through hole 24 is selected according to the size of the terminal block 42. For air conditioner models below 3P, there is usually one terminal block 42, and the first fixing through hole 24 is simply placed in the center of the fixing area. For air conditioner models above 3P, there are two terminal blocks 42, fixed side by side, and the position of the first fixing through hole 24 is determined based on the actual assembly position. After assembly, the terminal blocks 42 should be positioned as horizontally as possible to facilitate wiring and for an aesthetically pleasing appearance.

[0073] The mounting plate 31 is provided with a third fixing through hole 32, through which fasteners such as screws are used to directly install the wiring into the panel 41.

[0074] In this application, the edges of the limiting plate 11, the fixing plate 21, and the mounting plate 31 are all folded edges. A folded edge means that the limiting plate 11, the fixing plate 21, and the mounting plate 31 are folded towards the side away from the fixing of the terminal block 42, forming a folded edge structure. This folded edge structure ensures good strength for the terminal block bracket and also makes the edges of the bracket smooth, preventing sharp edges from scratching the signal lines or wires in the electrical box when assembled with the terminal block 42, signal lines, or electrical boxes.

A limiting plate 11 is provided at the top of the fixing plate 21 for limiting and fixing the magnetic ring 43; a mounting plate 31 is provided at the bottom of the fixing plate 21 for mounting the wiring bracket as a whole inside the panel 41.

[0077] In this embodiment, the junction box 42 is used to connect the signal line in the indoor unit of the air conditioner and the electrical box in the outdoor unit. A magnetic ring 43 is sleeved on the outside of the signal line.

[0078] The limiting plate 11 has a second fixing through hole 12, and the magnetic ring 43 is fixed in the second fixing through hole 12 by a binding wire 44. The signal line passes through the limiting plate 11 and enters the terminal block 42 position inside the fixing plate 21.

The number of second fixing through holes 12 can be specifically set according to the number of magnetic rings 43. At the same time, the second fixing through holes 12 need to be evenly distributed in the limiting plate 11 to avoid them being concentrated together and causing the magnetic rings 43 to touch each other.

[0079] The fixing plate 21 includes a grounding area and a fixing area for fixing the terminal block 42. The fixing area and the terminal block are respectively located on the left and right sides of the fixing plate 21. A grounding hole 22 is provided in the grounding area.

The first fixing through hole 24 is located in the center of the fixing area. The position of the first fixing through hole 24 is selected according to the size of the terminal block 42. For air conditioner models below 3P, there is usually one terminal block 42, and the first fixing through hole 24 is simply placed in the center of the fixing area. For air conditioner models above 3P, there are two terminal blocks 42, fixed side by side, and the position of the first fixing through hole 24 is determined based on the actual assembly position. After assembly, the terminal blocks 42 should be positioned as horizontally as possible to facilitate wiring and for an aesthetically pleasing appearance.

[0081] The mounting plate 31 is provided with a third fixing through hole 32, through which fasteners such as screws are used to directly install the wiring into the panel 41.

[0082] In this application, the edges of the limiting plate 11, the fixing plate 21, and the mounting plate 31 are all folded edges. A folded edge means that the limiting plate 11, the fixing plate 21, and the mounting plate 31 are folded towards the side away from the fixing of the terminal block 42, forming a folded edge structure. This folded edge structure ensures good strength for the terminal block bracket and also makes the edges of the bracket smooth, preventing sharp edges from scratching the signal lines or wires in the electrical box when assembled with the terminal block 42, signal lines, or electrical boxes.

[0083] Example 5

[0084] This application provides a wiring bracket for fixing a terminal block 42 and grounding the ground wire inside the terminal block 42. The wiring bracket includes a limiting plate 11, a fixing plate 21, and a mounting plate 31, wherein the fixing plate 21 is located between the limiting plate 11 and the mounting plate 31, and the limiting plate 11, fixing plate 21, and mounting plate 31 are bent together. A limiting plate 11 is provided at the top of the fixing plate 21 for limiting and fixing the magnetic ring 43; a mounting plate 31 is provided at the bottom of the fixing plate 21 for mounting the wiring bracket as a whole inside the panel 41. The limiting plate 11, fixing plate 21, and mounting plate 31 are all made of hot-dip galvanized steel sheet Q235A 0.95X1150XC, which is not easy to rust and corrosion and has high strength. Figure 4 As shown, the limiting plate 11 is a horizontal plate, the fixing plate 21 is a vertical plate, and the mounting plate 31 is an inclined plate extending away from the limiting plate 11.

[0085] In this embodiment, the junction box 42 is used to connect the signal line in the indoor unit of the air conditioner and the electrical box in the outdoor unit. A magnetic ring 43 is sleeved on the outside of the signal line.

[0086] The limiting plate 11 has a second fixing through hole 12, and the magnetic ring 43 is fixed in the second fixing through hole 12 by a binding wire 44. The signal line passes through the limiting plate 11 and enters the terminal block 42 position inside the fixing plate 21. The magnetic ring 43 on the outside of the signal line is blocked in the limiting plate 11. The limiting plate 11 has a second fixing through hole 12. The binding wire 44 is made of insulated wire. The magnetic ring 43 has a hollow ring structure and is sleeved on the outside of the signal line. The binding wire 44 passes through the hollow ring of the magnetic ring 43, passes through the edge of the limiting plate 11 to the second fixing through hole 12 and is tightened to fix the magnetic ring 43 in the limiting plate 11. The number of second fixing through holes 12 can be specifically set according to the number of magnetic rings 43. At the same time, the second fixing through holes 12 need to be evenly distributed in the limiting plate 11 to avoid them being concentrated together and causing the magnetic rings 43 to touch each other.

[0087] The fixing plate 21 includes a grounding area and a fixing area for fixing the terminal block 42. The fixing area and the terminal block are respectively located on the left and right sides of the fixing plate 21. A grounding hole 22 is provided in the grounding area. The grounding hole 22 is hexagonal, and the inner diameter of the grounding hole 22 is equal to the outer diameter of the grounding nut. The grounding nut is fixed inside the grounding hole 22. The grounding screw 25 fixes the ground wire to be grounded in the internal thread hole of the grounding nut. The ground wire to be grounded includes the ground wire in the signal line and the ground wire in the electrical box.

[0088] A first fixing through hole 24 is provided within the fixing area, and the terminal block 42 is fixed within the first fixing through hole 24. The first fixing through hole 24 is located in the center of the fixing area. The position of the first fixing through hole 24 is selected according to the size of the terminal block 42. For air conditioner models below 3P, there is usually one terminal block 42, and the first fixing through hole 24 is simply placed in the center of the fixing area. For air conditioner models above 3P, there are two terminal blocks 42, fixed side by side, and the position of the first fixing through hole 24 is determined based on the actual assembly position. After assembly, the terminal blocks 42 should be positioned as horizontally as possible to facilitate wiring and for an aesthetically pleasing appearance.

[0089] The mounting plate 31 is provided with a third fixing through hole 32, through which fasteners such as screws are used to directly install the wiring into the panel 41.

[0090] In this application, the edges of the limiting plate 11, the fixing plate 21, and the mounting plate 31 are all folded edges. A folded edge means that the limiting plate 11, the fixing plate 21, and the mounting plate 31 are folded towards the side away from the fixing of the terminal block 42, forming a folded edge structure. This folded edge structure ensures good strength for the terminal block bracket and also makes the edges of the bracket smooth, preventing sharp edges from scratching the signal lines or wires in the electrical box when assembled with the terminal block 42, signal lines, or electrical boxes.
