Description

Technical Field

[0001] The utility model belongs to the technical field of stator accessories of fixed-frequency motors, and particularly relates to an insulating paper for fish line phase separation with a fixing structure. Background Art

[0002] During the production process of motor windings, the insulating paper for phase separation is mainly used as the phase insulation of the motor windings. The use of this component is not only to ensure the electrical safety of the motor windings, but also to protect the motor from electrical faults.

[0003] The existing integrated punching sheet insulating paper for phase separation has a high production cost and the connecting wire width is greater than the slot opening. The upper and lower phase separation sheets have the same thickness and are both relatively thin, resulting in difficulties in placing them into the slot holes. The fish line type insulating paper for phase separation has a lower production cost than the integrated punching sheet insulating paper for phase separation, and the connecting wire uses the form of fish line. However, due to the fish line being too thin, in actual operation, the connecting fish line of the insulating paper is easily disengaged from the slot hole.

[0004] Regarding a fish line welded flat type insulating paper for phase separation provided by the utility model patent (application number: 202020714369.X), it is set that the fish line is clamped in the slot by adding flat points on the fish line to prevent it from disengaging, but there are still certain problems: First, when placing the fish line with flat points into the card slot, it is necessary to continuously adjust the posture of the flat points so that it can be placed into the card slot, which increases the operation difficulty and consumes assembly time; Second, after placing the fish line with flat points into the card slot, in the subsequent assembly process, the structure of the fish line without flat points is still easily disengaged from the card slot; Third, there is still a certain gap between the fish line and the card slot after the fish line is installed in the card slot. Even if flat points are set, the fish line will still shake in the card slot, especially the two ends where the fish line is connected to the insulating paper are easily disengaged from the card slot, making the overall structure unstable and affecting the assembly applicability. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an insulating paper for fish line phase separation with a fixing structure. By setting two insulating structures with inconsistent insulating paper thicknesses connected by fish lines to form the insulating paper for fish line phase separation, it is convenient to operate and install when placing the insulating paper into the stator card slot. At the same time, an arc structure and flat solder joints are set at the connection between the insulating paper and the fish line, so that after the insulating paper is placed into the stator card slot, the insulating paper can be stably clamped in the card slot, without shaking and not easily disengaging.

[0006] In order to achieve the above purpose, the utility model is realized by the following technical solutions:

[0007] In a first aspect, an embodiment of the present utility model provides a fish-line alternating insulating paper with a fixing structure, which includes an insulating paper and a plurality of fish lines; the insulating paper includes a first insulating structure and a second insulating structure, and the thicknesses of the first insulating structure and the second insulating structure are different; both ends of the plurality of fish lines are respectively connected to the first insulating structure and the second insulating structure, and arc structures are provided at the connection positions of the first insulating structure and the second insulating structure with the plurality of fish lines.

[0008] As a further technical solution, the plurality of fish lines are cylindrical.

[0009] As a further technical solution, the plurality of fish lines have the same size.

[0010] As a further technical solution, the plurality of fish lines are arranged parallel to each other.

[0014] As a further technical solution, the size of the arc structure is larger than the size of the flat solder joint.

[0015] As a further technical solution, the first insulating structure and the second insulating structure have the same length.

[0016] As a further technical solution, the length of the first insulating structure is greater than the width between the arc structures provided on the first insulating structure.

[0017] The beneficial effects of the above embodiments of the present utility model are as follows:

[0018] The fish-line alternating insulating paper with a fixing structure provided by the present utility model is composed of two insulating papers with different thicknesses connected by fish lines to form a fish-line alternating insulating paper. By operating the thicker insulating paper with one hand, the thinner insulating paper can be driven to pass through the stator aperture. When the fish line and the card slot reach the appropriate installation position, the fish line and the arc structure at its connection with the insulating paper are pressed into the card slot to complete the installation, which facilitates the operation and installation of placing the insulating paper into the stator card slot;

[0019] Meanwhile, an arc structure and a flat solder joint are provided at the connection between the insulating paper and the fishing line, making the connection between the insulating paper and the fishing line more stable. Also, after the insulating paper is placed into the stator slot, the arc structures at both ends of the insulating paper connected to the fishing line can be stably clamped in the slot, without shaking and not easily falling out. The overall structure is stable, facilitating assembly and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] It should be noted that the following detailed descriptions are all exemplary and are intended to provide a further explanation of this utility model. Unless otherwise specified, all technical and scientific terms used in this utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs.

[0026] Embodiment 1

[0027] In a typical implementation manner of this utility model, as Figure 1 shown, a fishing line interphase insulating paper with a fixed structure is provided, including an insulating paper and a plurality of fishing lines 3; the insulating paper includes a first insulating structure 1 and a second insulating structure 2, and the thicknesses of the first insulating structure 1 and the second insulating structure 2 are different; both ends of the plurality of fishing lines 3 are respectively connected to the first insulating structure 1 and the second insulating structure 2, and arc structures 4 are provided at the connections between the first insulating structure 1 and the second insulating structure 2 and the plurality of fishing lines 3.

[0028] In this embodiment, when the thickness of the first insulating structure 1 is greater than that of the second insulating structure 2, the thickness of the first insulating structure 1 is 0.125 mm, and the thickness of the second insulating structure 2 is 0.25 mm; when the thickness of the first insulating structure 1 is less than that of the second insulating structure 2, the thickness of the first insulating structure 1 is 0.25 mm, and the thickness of the second insulating structure 2 is 0.125 mm. It should be noted that in other embodiments of the present utility model, the thicknesses of the first insulating structure 1 and the second insulating structure 2 can adopt other dimensions, as long as the thicknesses of the two are different and deformation assembly can be completed.

[0029] By setting two insulating papers with different thicknesses connected by fishing lines 3 to form a fishing line-interleaved insulating paper, the thicker insulating paper can be driven by single-hand operation to drive the thinner insulating paper through the stator aperture. When the fishing line 3 and the card slot reach the appropriate installation position, the fishing line 3 and the arc structure 4 at its connection with the insulating paper are pressed into the card slot to complete the installation, which facilitates the operation and installation of placing the insulating paper into the stator card slot.

[0030] Furthermore, multiple fishing lines 3 are cylindrical, the multiple fishing lines 3 have the same size, and the multiple fishing lines 3 are arranged parallel to each other. Both ends of the multiple fishing lines 3 are fixedly connected to the first insulating structure 1 and the second insulating structure 2 by welding respectively. In this embodiment, two cylindrical fishing lines 3 with the same size are provided, and both ends are respectively connected to the first insulating structure 1 and the second insulating structure 2. The two fishing lines 3 are parallel to each other, and both ends of the two fishing lines 3 are fixedly connected to the first insulating structure 1 and the second insulating structure 2 by welding respectively. With such a setting, the problem of relatively high material cost existing in the existing punched sheet type phase-interleaved insulating paper during the stator production process is improved.

[0031] At the same time, flat solder joints 5 are provided at the connection parts where both ends of the multiple fishing lines 3 are connected to the first insulating structure 1 and the second insulating structure 2. The flat solder joints 5 are arranged on the arc structure 4, and the size of the arc structure 4 is larger than that of the flat solder joints 5. In this embodiment, four flat solder joints 5 are provided at the connection parts between the two fishing lines 3 and the first insulating structure 1 and the second insulating structure 2. The four flat solder joints 5 are arranged on four arc structures 4, and the size of the arc structure 4 is larger than that of the flat solder joints 5. The arc structure 4 and the flat solder joints 5 are provided at the connection part between the insulating paper and the fishing line 3, making the connection part between the insulating paper and the fishing line 3 more stable. Also, after the insulating paper is placed into the stator card slot, the two ends of the insulating paper connected to the fishing line 3 can be stably clamped in the card slot through the arc structures 4 at both ends, without shaking and not easily coming out. The overall structure is stable and convenient for assembly and use. It ensures that the fishing line 3 does not come out of the stator slot during the production process, and solves the problem that the strip-shaped sheet exposes out of the stator slot after the stator enters the auxiliary phase wire.

[0032] The length of the first insulating structure 1 is consistent with that of the second insulating structure 2, and the length of the first insulating structure 1 is greater than the width between the arc structures 4 arranged on the first insulating structure 1. Such arrangement ensures that the fishing line 3 can be stably connected between the first insulating structure 1 and the second insulating structure 2, thereby enhancing the stability of the overall structure of the insulating paper.

[0033] like Figure 2 As shown, a method for using a fishing line interphase insulating paper with a fixed structure provided in Example 1 of the utility model includes:

[0034] When the thickness of the first insulating structure 1 is greater than that of the second insulating structure 2, the worker bends the first insulating structure 1 with one hand, and the thickness of the second insulating structure 2 is smaller, so it is easy to be stressed and deform accordingly with the deformation of the first insulating structure 1;

[0035] The staff passes the bent insulating paper through the through hole in the middle of the motor stator with one hand. After reaching the appropriate installation position, the staff aligns the fishing line with the slots between the motor stators. The arc structure 4 of the first insulating structure 1 and the second insulating structure 2 are also aligned with the two ends of the slots and pressed into the slots.

[0036] During the pressing process, the first insulating structure 1 and the arc structure 4 of the second insulating structure 2 can be pressed into the slot respectively, or the first insulating structure 1 and the arc structure 4 of the second insulating structure 2 can be pressed into the slot together to complete the assembly.

[0037] The above operation process allows the staff to operate with one hand, and at the same time avoids the operation steps of constantly adjusting the position of the fishing line 3 to make it fit into the slot during the installation process, simplifies the installation operation, and reduces the single operation cycle of the motor. At the same time, the arc structure 4 can make the insulating paper as a whole stably clamped in the slot, making it difficult for the fishing line 3 to fall out of the slot.

[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
