[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 7It is known that a structure for fixing a wire harness on a control cabinet door includes a first fixing groove 2 and a second fixing groove 3 on the inner side of the cabinet door 1. A fixing hole 4 is provided below the first fixing groove 2 and the second fixing groove 3. The first fixing groove 2 is located slightly to the left above the fixing hole 4. A second fixing plate is located slightly to the right above the fixing hole 4. A first wire groove 5 is fixed in the first fixing groove 2. A second wire groove 6 is fixed in the second fixing groove 3. A third wire groove 7 is fixed below the first wire groove 5 and the second wire groove 6. A connecting plate 8 is provided below the first wire groove 5 and the second wire groove 6. A first through hole 9 that mates with the fixing hole 4 is provided on the connecting plate 8. A second through hole 10 is provided on the third wire groove 7. Fixing screws are used to pass through the first through hole 9 and the second through hole 10 in sequence and threadedly connect to the fixing hole 4 to fix the third wire groove 7, the first wire groove 5 and the second wire groove 6 on the inner side of the cabinet door 1.

[0020] In practical use, this utility model The control cabinet door 1 is made of double-layer steel plate. The first fixing groove 2 and the second fixing groove 3 are opened on the inner steel plate. The first wire groove 5 and the second wire groove 6 are fixed to the first fixing groove 2 and the second fixing groove 3 respectively. Then, the third wire groove 7 is connected to the first wire groove 5 and the second wire groove 6, thereby fixing the third wire groove 7, the first wire groove 5 and the second wire groove 6 to the inside of the cabinet door 1. Then, the wiring harness is connected and fixed in the third wire groove 7, the first wire groove 5 and the second wire groove 6.

[0021] In this structure, the first groove 5, the second groove 6 and the third groove 7 can quickly complete the connection with the cabinet door 1, and the cabinet door 1 only needs to be grooved and drilled during processing, without too many processes, so as not to increase the production cost too much.

[0022] The back side of the first groove 5 is provided with a first retaining strip 11 that is inserted into the first fixing groove 2, and the back side of the second groove 6 is provided with a second retaining strip 12 that is inserted into the second fixing groove 3. Both the first retaining strip 11 and the second retaining strip 12 are L-shaped structures, and the first retaining strip 11 and the second retaining strip 12 are oriented in opposite directions.

[0023] The thickness of the steel plate used for the first clip 11 and the second clip 12 is less than the width of the first fixing groove 2 and the second fixing groove 3, so that they can be smoothly inserted into them. After the first wire groove 5 and the second wire groove 6 are connected to the cabinet door 1, the third wire groove 7 is used to fix the position of the first wire groove 5 and the second wire groove 6. After the third wire groove 7, the first wire groove 5 and the second wire groove 6 are fixed, the first clip 11 and the first fixing groove 2, and the second clip 12 and the second fixing groove 3 form a limit, so that the whole formed by the third wire groove 7, the first wire groove 5 and the second wire groove 6 is fixed to the cabinet door 1. Then, screws are used to fix it to the fixing hole 4 to ensure the stability of the wire groove.

[0024] In this structure, the fixed connection of multiple first grooves 5, second grooves 6 and third grooves 7 can be achieved with a small number of screws, simplifying the installation steps and improving installation efficiency.

[0025] The third groove 7 has a notch 13 corresponding to the first groove 5 and the second groove 6. The bottom of the third groove 7 has a relief groove 14 corresponding to the first connecting plate 8 and the second connecting plate 8. The outer edges of the upper sides of the first groove 5, the second groove 6 and the third groove 7 are all provided with protrusions 15. The top of the first groove 5, the second groove 6 and the third groove 7 are all fastened with cover plates 16.

[0026] The notch 13 ensures the continuity between the wire troughs, and the clearance groove 14 keeps the third wire trough 7 at the same height as the first wire trough 5 and the second wire trough 6. The cover plate 16 is connected to the first wire trough 5, the second wire trough 6 and the third wire trough 7 by means of a snap-fit, protecting the wire harness in the wire trough. The cover plate 16 is also easy to remove for later maintenance and replacement.

[0027] Compared with the prior art, this utility model has the following advantages: a detachable wire trough is provided on the inside of the cabinet door, which can quickly complete the assembly of the wire trough and fix the wire harness in the wire trough, thereby protecting the wire harness, reducing the mess caused by the wire harness, and eliminating safety hazards.
