[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: An internal wire of an inverter includes a wire body 1. The wire body 1 is a prior art. It is an internal wire of an inverter. Generally, multiple groups of it are connected to a circuit board together to provide signal transmission for the device. And those skilled in the art can implement it. Since it is a prior art, no more description will be made in this case. A connection component 2 is provided on the outer wall of the front end of the wire body 1. A fixing component 3 is provided on the inner wall of the connection component 2. Multiple groups of connection components 2 are provided, and each group is matched and installed with a group of wire bodies 1, which can quickly fix the wire bodies 1. The connection component 2 includes a first arc-shaped block 21. The first arc-shaped block 21 contacts the upper surface of the front end of the wire body 1. A second arc-shaped block 22 contacts the lower surface of the first arc-shaped block 21. The second arc-shaped block 22 contacts the lower surface of the front end of the wire body 1. The first arc-shaped block 21 and the second arc-shaped block 22 have a certain curvature, which fits the outer wall of the wire body 1. At the same time, the part in contact with the wire body 1 is made of rubber material to ensure the stability of fixation. A connection shell 27 is fixedly connected to the left surface of the second arc-shaped block 22.
[0031] Reference Figure 2 - Figure 3 As shown in Figure 3 , the fixing component 3 includes a bolt 31. The bolt 31 is a prior art, which is a rod-shaped structure with threads on its outer wall, adapted to the threaded hole 35, and has the characteristic of axial self-locking to ensure the stability of the connection. The bolt 31 passes through and is threadedly connected to the left end of the upper surface of the first arc-shaped block 21. A threaded hole 35 is provided on the upper surface of the left end of the second arc-shaped block 22, and the bolt 31 is threadedly connected to the inner wall of the threaded hole 35.
[0032] Reference Figure 2 As shown in Figure 2 , a clamping block 25 is elastically connected to the inner wall of the connecting shell 27 through a first spring 26. The first spring 26 has a certain elasticity and always pushes the clamping block 25 backward through its elasticity to ensure the stability of the limit of the clamping block 25. The clamping block 25 passes through and is slidably connected to the rear surface of the top of the connecting shell 27. One end of the first spring 26 is fixedly connected to the inner wall of the connecting shell 27, and the other end of the first spring 26 is fixedly connected to the front surface of the clamping block 25. The rear surface of the clamping block 25 is set as an inclined surface to ensure the quick connection of multiple groups of wire bodies 1.
[0033] Reference Figure 2 As shown in Figure 2 , the lower surface of the clamping block 25 is fixedly connected to the inner wall of the sliding plate 24. The sliding plate 24 is slidably connected to the inner wall of the connecting shell 27. A push plate 23 is fixedly connected to the front surface of the sliding plate 24. The push plate 23 is convenient for workers to release the connection between multiple groups, improving the practicability. The push plate 23 passes through and is slidably connected to the rear surface of the connecting shell 27. A rectangular shell 28 is fixedly connected to the right surface of the first arc-shaped block 21, and a rectangular groove 29 is provided in the inner wall of the rectangular shell 28.
[0034] Reference Figure 2 、 Figure 4 As shown in Figure 4 , a sliding column 33 is elastically connected to the inner wall of the second arc-shaped block 22 through a second spring 34. The second spring 34 always pushes the sliding column 33 upward through its own elasticity to ensure that when adjusting the position of the connecting component 2, the ball 32 can always contact the outer wall of the wire body 1, improving the smoothness of the adjustment. The sliding column 33 is slidably connected to the inner wall of the second arc-shaped block 22. One end of the second spring 34 is fixedly connected to the inner wall of the second arc-shaped block 22, and the other end of the second spring 34 is fixedly connected to the lower surface of the sliding column 33. A ball 32 is slidably connected to the inner wall of the top end of the sliding column 33. The ball 32 can reduce the friction of the adjusting connecting component 2, improving the practicability. The ball 32 rolls on the outer wall of the wire body 1. Multiple groups of balls 32, sliding columns 33, and second springs 34 are provided. Setting multiple groups of balls 32, sliding columns 33, and second springs 34 can ensure the stability of the movement of the connecting component 2, and multiple groups of balls 32, sliding columns 33, and second springs 34 are evenly arranged on the upper surface of the second arc-shaped block 22.
[0035] Working principle: When it is necessary to fix multiple groups of wire bodies 1 together during use, it is only necessary to connect the connection components 2 provided on the outer walls of multiple groups of wire groups. During connection, it is only necessary to insert the connection shell 27 of one group of connection components 2 into the inner wall of the rectangular shell 28 in another group of connection components 2. During the insertion process, the rectangular shell 28 will push it to move along the inclined surface of the clamping block 25. The clamping block 25 will mobilize the slide plate 24 to move and compress the first spring 26 until the clamping block 25 overlaps with the rectangular groove 29. At this time, the first spring 26 will push the clamping block 25 to move in the reverse direction through its own elasticity and insert it into the outer wall of the rectangular groove 29, which is fast and convenient. When disassembling, just push the push plate 23. The push plate 23 will drive the clamping block 25 to move through the slide plate 24, so that the clamping block 25 disengages from the inner wall of the rectangular groove 29. The following structural cooperation methods are the same as above.
[0036] When it is necessary to adjust the position of the connection component 2 on the outer wall of the wire body 1, it is only necessary to use a tool to rotate the bolt 31, so that a distance is generated between the first arc-shaped block 21 and the second arc-shaped block 22. It is impossible to make the bolt 31 disengage from the inner wall of the threaded hole 35. At this time, the second spring 34 will push the sliding column 33 to move through its own elasticity, and the ball 32 will also move accordingly. Multiple second springs 34 will drive the sliding column 33 to move through their own elasticity to support the first arc-shaped block 21 and the second arc-shaped block 22. At this time, the position of the connection component 2 can be moved. During the movement, the ball 32 will roll on the outer wall of the wire body 1, reducing the friction force and improving the practicability. After the adjustment is completed, reverse the bolt 31 to merge the first arc-shaped block 21 and the second arc-shaped block 22 together. At this time, the ball 32 will be received into the inner wall of the second arc-shaped block 22 under the elastic action of the second spring 34, increasing the stability.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
