[0045] A plurality of line cards 2 are provided, one of which is detachably mounted on a limiting portion. The line card 2 is provided with a first card slot 21 for inserting the wire harness 01 , and the opening of the first card slot 21 faces the notch 12 .

[0046] Specifically, the wire trough device is preferably used in an air conditioner outdoor unit. A cavity 11 for placing the wire harness 01 is provided in the wire trough body 1. The cavity 11 is preferably set through the wire trough body 1. The slot 12 is located on one side of the cavity 11, that is, the slot 12 is provided on one side of the wire trough body 1. The slot 12 is connected to the cavity 11. The slot 12 is not only convenient for wire outlet, but also conducive to heat dissipation; the limiting part is preferably located on the side of the cavity 11 away from the slot 12, so as to facilitate the fixing of the wire card 2; the wire harness 01 can be wired out from the target outlet position of the slot 12. The target outlet position can be one or more, and the number and specific position of the target outlet position can be set as needed. The wire card 2 is detachably mounted on a limiting portion, and its purpose is to limit the wire harness 01. There are multiple wire cards 2, and different positions of the wire harness 01 can be limited.

[0047] The wire trough device provided by the utility model can hide the wire harness 01 in the cavity 11 of the wire trough body 1 through the setting of the wire trough body 1 and the provision of a cavity 11 in the wire trough body 1, thereby ensuring the neatness and beauty of the wire harness 01 and reducing safety hazards; at the same time, through the setting of the wire card 2, the wire harness 01 can be segmented and restricted on the wire trough body 1, which not only ensures the stability of the wire harness 01, but also because the wire card 2 limits the segmented position of the wire harness 01, the target outlet position can be selected at will for the outlet of the wire harness 01, which meets the use requirements and has a wide range of applications; in addition, through the detachable connection between the wire card 2 and the limiting part, the flexibility of the position of the wire card 2 can be improved, ensuring the stable limitation and flexible layout of the wire harness 01.

[0048] In some embodiments, a plurality of first stoppers 3 are also included. The first stoppers 3 are installed on the notch 12 of the wire trough body 1, and the first stoppers 3 can slide to the target outlet position, and the wire harness 01 passes through the first stoppers 3 and then comes out. Preferably, the first stoppers 3 are rubber parts, and a cross is opened in the center of the rubber part, and the wire harness 01 passes through the cross of the first stoppers 3 to prevent the wire harness 01 from shaking. The contour of the first stoppers 3 is preferably square, and the first stoppers 3 are installed in the notch 12 of the wire trough body 1 with interference fit. At the same time, the first stoppers 3 can be pushed with force to change the position of the first stoppers 3, so as to facilitate the position adjustment. Furthermore, the first stoppers 3 can be directly installed at the target outlet position, or they can be installed at will and then adjusted to the target outlet position.

[0049] In some embodiments, at least one side of the wire trough body 1 is also provided with a plurality of wire openings 13 for placing the wire harness 01 into the cavity 11 or for extending the wire harness 01 from the cavity 11, and the wire openings 13 and the slots 12 are located on different sides of the wire trough body 1. Specifically, the setting positions of the wire openings 13, the setting positions of the slots 12, and the setting positions of the limiters are preferably set on different sides of the wire trough body 1 to facilitate the placement of the wire harness 01. The above settings can ensure flexible selection of the incoming line position, as well as flexible selection of the outgoing line position and the outgoing line direction.

[0050] In some embodiments, a second stopper 4 is further included which is installed at the wire port 13. Specifically, the second stopper 4 is preferably a rubber member, and a cross is provided at the center of the rubber member, and the wire harness 01 passes through the cross of the second stopper 4 to prevent the wire harness 01 from shaking. The outer contour of the second stopper 4 should be the same as the contour of the wire port 13, and both are preferably circular, matching the shape of the wire harness 01, and convenient for processing.

[0051] In some embodiments, in addition to the cavity 11, the wire trough body 1 is also provided with an avoidance cavity 14. When the wire trough body 1 is installed on the sheet metal of the electrical appliance, screws can be used to assemble it through the avoidance cavity 14. The setting of the avoidance cavity 14 can prevent the screws from causing damage to the wiring harness 01.

[0052] In some embodiments, Figure 5-1 and Figure 5-2 As shown, the line card 2 includes a line card body and a card stand 22. The card stand 22 and the first card slot 21 are respectively located on both sides of the line card body, and the card stand 22 and the limit portion are detachably connected. Preferably, the line card 2 is made of soft material, preferably rubber, but plastic is also acceptable. Specifically, one side of the line card 2 is used to be assembled on the line slot body 1, and the other side is used to limit the position of the wire harness 01. The card stand 22 and the limit portion can both be buckles, and the card stand 22 can be hung on the limit portion.

[0053] Preferably, the limiting part is a plurality of limiting holes provided on the wire trough body 1, and a shrinkage gap is provided in the middle of the clamping platform 22 for the clamping platform 22 to be clamped into the limiting hole. The limiting hole is convenient to provide, and the processing cost is low, which is beneficial to reducing the weight and saving materials of the wire trough body 1. At the same time, by providing a shrinkage gap in the middle of the clamping platform 22, when the clamping platform 22 is inserted into the limiting hole, the clamping platform 22 can be deformed, which is convenient for assembly. At the same time, after the clamping platform 22 is inserted into the limiting hole, under the action of elastic deformation, the clamping platform 22 restores its initial shape and is firmly clamped with the limiting hole.

[0054] In some embodiments, the first slot 21 is arc-shaped or square-shaped, and an introduction arc surface is provided on both sides of the opening of the first slot 21. Specifically, by setting the introduction arc surface, the wire harness 01 can be easily pushed into the first slot 21; further, the arc-shaped first slot 21 is suitable for multiple wire harnesses 01, or a single thicker wire harness 01, and the square first slot 21 is suitable for a wire harness 01 with a terminal row. By setting the introduction arc surface, the wire harness 01 with a terminal row is easier to be inserted into the first slot 21, which is convenient for assembly.

[0055] In some embodiments, at least one side of the card slot of the line card 2 is further provided with a limiting gap 23 for fixing the wire harness 01. Specifically, by providing the limiting gap 23 on the line card 2, some wire harnesses 01 with smaller diameters, such as wire harnesses 01 with a diameter less than 4 mm, can be wound in the limiting gap 23 to limit the position of such wire harnesses 01, and have a good fixing effect for one or two thin wire harnesses 01 entering from the side, further improving the scope of application, while not affecting the original function of the line card 2.

[0056] In some embodiments, the limiting gap 23 is in an arc, wave or folded line shape, and the extending direction of the limiting gap 23 is perpendicular to the extending direction of the wire trough body 1. Specifically, by setting the arc, wave or folded line shape, the position of the wire harness 01 with a smaller diameter can be more stable to avoid slipping out, and the extending direction of the limiting gap 23 is perpendicular to the extending direction of the wire trough body 1, which can also ensure that the wire harness 01 with a smaller diameter is not easily pulled and has a stable position.

[0057] In some embodiments, Figure 3 , Figure 4-3 , Figure 6-1 and Figure 6-2 As shown, the line card 2 is strip-shaped, and the line card 2 is detachably installed in the cavity 11 of the line slot body 1. The line card 2 is provided with a second card slot 25, and the opening of the second card slot 25 faces the slot 12;

[0058] The device further comprises a plurality of cover plates 6 , with a spacing between adjacent cover plates 6 . The cover plates 6 are mounted on the second card slots 25 of the line card 2 , and the cover plates 6 can slide relative to the second card slots 25 .

[0059] Specifically, the above-mentioned line card 2 is different from the line card 2 structure given above. The line card 2 is suitable for a larger wire trough body 1, which is generally placed at the bottom of the device and is suitable for a large number of wire harnesses 01, or a large terminal row of wire harnesses 01, and a complex incoming line position. Furthermore, there is a spacing between adjacent cover plates 6, which can not only enable the wire harness 01 to exit from between adjacent cover plates 6, but also ensure the heat dissipation effect. Furthermore, in order to facilitate the connection between the line card 2 and the cover plate 6, the line card 2 and the cover plate 6 are provided with a bent edge. After the bent edge of the cover plate 6 is buckled with the bent edge of the line card 2, the cover plate 6 cannot be pulled out horizontally and can only slide in the extension direction of the line card 2.

[0060] Preferably, the side of the wire card 2 is also provided with a plurality of avoidance grooves 24 for the wire harness 01 to be placed in the second card slot 25, and each avoidance groove 24 is arranged along the length direction of the wire slot body 1. The avoidance grooves 24 are U-shaped. On the one hand, they can be ventilated and dissipate heat, and on the other hand, the wire harness 01 with a smaller diameter can enter the second card slot 25 through the avoidance grooves 24. Therefore, the above-mentioned wire card 2 is suitable for thin wire harness 01 + wire harness 01 with terminal blocks. Thin wire harness 01 generally refers to a wire harness 01 with a diameter of less than 4 mm.

[0061] In some embodiments, a bottom plate 5 is further included, and the wire trough body 1 is mounted on the bottom plate 5. The bottom plate 5 is provided with a connection portion 51 for detachably connecting with the electrical board. Specifically, the wire trough body 1 and the bottom plate 5 can be fixed by hot-melt welding to ensure the connection strength; the connection portion 51 is preferably a connection hole provided on the bottom plate 5, and the connection hole and the electrical board are connected by bolts. When the wire trough device needs to be disassembled and maintained, the bottom plate 5 can be disassembled, which is convenient to operate and efficient. Preferably, as Figure 7 As shown, in order to avoid interference between the bottom plate 5 and other structures inside the appliance, an arc chamfer is preferably provided on the edge of the bottom plate 5 .

[0062] In some embodiments, Fig.10 As shown, it also includes a middle cross wire groove 7, and the two ends of the middle cross wire groove 7 are respectively connected to the wire groove bodies 1 on the left and right sides, so that the wire harness 01 between the two wire groove bodies 1 can pass through. Specifically, in order to prevent the wire harness 01 from piling up between the two wire groove bodies 1, the middle cross wire groove 7 is added to hide the wire harness 01; specifically, as shown Fig. 9As shown, a mounting groove 15 is provided in the middle of the wire trough body 1. The mounting grooves 15 of the two wire trough bodies 1 located on the left and right sides of the inside of the appliance are opposite to each other. The two ends of the middle cross wire trough 7 are respectively fixed in the mounting groove 15, and then fixed by hot-melt welding. Of course, when there are many wire harnesses 01 between the two wire trough bodies 1 on the left and right sides of the inside of the appliance, in addition to the middle cross wire trough 7, at least one horizontally placed wire trough body 1 can also be set at the same time, and it can also be assembled through the mounting groove 15. Of course, the above-mentioned wire trough body 1 should be used with the wire card 2, the first limiter 3 and / or the second limiter 4.

[0063] In a specific embodiment, the wire trough body 1 includes at least one of a first wire trough body 1, a second wire trough body 1 and a third wire trough body 1. A wire card 2 having an arc-shaped first card slot 21 is installed in the first wire trough body 1, which is suitable for fixing a small amount of small wire harnesses 01; a wire card 2 having a square first card slot 21 is installed in the second wire trough body 1, which is suitable for fixing a thicker wire harness 01 or a wire harness 01 that needs to be combined with a terminal; a strip wire card 2 is installed in the third wire trough body 1, which is used in conjunction with a cover plate 6 and is suitable for fixing a large number of wire harnesses 01 or a wire harness 01 with a larger terminal row.

[0064] Further, for the wire harness 01 from different directions, first, the type of the wire trough body 1 and the wire clip 2 are selected according to the type of the wire harness 01 to be fixed, and then the height of the wire trough body 1 is determined according to the position of the incoming wires. A plurality of fixing holes 16 are provided on the wire trough body 1, such as Figure 8 As shown, the fixing hole 16 is fixed to the sheet metal of the electrical appliance and can be connected by screws. The bottom plate 5 and the wire trough body 1 are fixed to the electrical appliance board body by hot melt welding; the left sheet metal and the right sheet metal inside the electrical appliance can be connected to the first wire trough body 1 and the second wire trough body 1 respectively, and fixed by screws. The third wire trough body 1 can be installed at the bottom of the electrical appliance, and a large number of wire harnesses 01 can be hidden in the third wire trough body 1 at the bottom.

[0065] The wire trough device can hide the wire harness 01, avoiding irregular bundling and accumulation of outgoing wires; at the same time, Fig.11 As shown, wire harnesses 01 in different directions can be fixed, and according to the number of wire harnesses 01, different types of wire duct bodies 1 and wire cards 2 are selected for fixing, so as to realize free and flexible wire entry and free and flexible wire exit.
