Description

Technical Field

[0001] This utility model relates to the field of generators, and in particular to a flexible connecting wire for rotor assembly. Background Technology

[0002] Generators generate continuous vibrations during operation. The connecting wires to the rotor are affected by the vibrations, which can easily lead to metal fatigue, increased conductor resistance, or even poor connections. In severe cases, this can cause generator malfunction. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution;

[0006] The flexible connecting wire for rotor assembly is made of five bent and stacked copper sheets:

[0007] The copper sheet comprises a first segment, a second segment, a third segment, a fourth segment, a fifth segment, and a sixth segment connected in sequence;

[0008] The longitudinal section of the first segment is line-segment shaped and located in the horizontal direction;

[0009] The longitudinal section of the second segment is in the shape of a quarter circle, with the opening facing the upper left.

[0010] The longitudinal section of the third segment is semi-circular and the opening faces downward;

[0011] The longitudinal section of the fourth segment is line-segment shaped and located in the vertical direction;

[0012] The longitudinal section of the fifth segment is in the shape of a quarter-circle arc, with the opening facing the upper left.

[0013] The longitudinal section of the sixth segment is line segment-shaped and located in the horizontal direction, and the sixth segment has a through hole running vertically through it.

[0014] In the second, third, and fifth sections, there is a gap between two adjacent copper sheets;

[0015] In the first segment, the fourth segment, and the sixth segment, there is no gap between two adjacent copper sheets.

[0016] The above design features a flexible connecting wire composed of six interconnected segments, which effectively disperses the impact from generator operation. The second, third, and fifth segments are all arc-shaped, and there are gaps between adjacent copper sheets. These gaps help to distribute stress, allowing for a more even distribution of force on the flexible connecting wire during use, especially during frequent bending. This reduces local stress concentration, improves fatigue resistance, and extends service life.

[0017] Preferably, the upper and lower surfaces of each copper sheet are covered with a silver plating layer with a thickness of 0.013 mm. This increases the wear resistance of each copper sheet, thereby improving its service life. The silver plating also enhances the mechanical strength of the flexible connection wire, making it more durable under frequent movement and vibration.

[0018] Preferably, each copper sheet has a silver plating layer with a thickness of not less than 0.1 mm on its side, and the five copper sheets are connected together at the first, fourth, and sixth segments by the silver plating layer on their sides. Connecting the first, fourth, and sixth segments by the silver plating layer improves their strength and extends their service life.

[0019] Preferably, the thickness of each copper sheet is 0.7-0.9 mm, and the maximum gap between two adjacent copper sheets is 0.2-0.3 mm; this ensures that each copper sheet has sufficient strength, and the maximum gap between the copper sheets can ensure that the second, third and fifth sections can absorb the bending impact from the relative displacement of the two connecting ends, thus better dispersing stress.

[0020] Preferably, the copper sheet has the same width of 30.5mm at the first, second, third, fourth, and fifth segments; the sixth segment consists of a first part connecting to the fifth segment and a second part away from the fifth segment. The width of the first part is 30.5mm, and the end of the second part away from the fifth segment is a semi-circular arc with a radius of 30.5mm. The opening is located on the second part and is an elliptical hole; the elliptical hole facilitates the connection and fixation of the flexible connecting wire.

[0021] Preferably, the length of the sixth segment is 107.3 mm, and the length of the first segment is 23.3 mm; the distance from the end face of the first segment away from the second segment to the fourth segment is less than the minimum distance from the opening to the fourth segment; to avoid the opening being blocked by the first segment, affecting the assembly of the flexible connection wire.

[0022] Preferably, in the second, third, and fifth segments, the gaps between two adjacent copper sheets are filled with liquid metal; the liquid metal can effectively absorb impacts and improve the service life of the flexible connection. Attached Figure Description

[0031] Example 1

[0032] Reference Figures 1-3The flexible connecting wire for rotor assembly is made of five copper sheets bent and stacked together.

[0033] The copper sheet 8 comprises a first segment 1, a second segment 2, a third segment 3, a fourth segment 4, a fifth segment 5, and a sixth segment 6 connected in sequence. The longitudinal section of the first segment 1 is a line segment and is located in the horizontal direction. The longitudinal section of the second segment 2 is a quarter-circle arc and the opening 61 faces the upper left. The longitudinal section of the third segment 3 is a semi-circle arc and the opening 61 faces downward. The longitudinal section of the fourth segment 4 is a line segment and is located in the vertical direction. The longitudinal section of the fifth segment 5 is a quarter-circle arc and the opening 61 faces the upper left. The longitudinal section of the sixth segment 6 is a line segment and is located in the horizontal direction. The sixth segment 6 has a through hole running vertically. In the second segment 2, the third segment 3, and the fifth segment 5, there is a gap 7 between two adjacent copper sheets 8. In the first segment 1, the fourth segment 4, and the sixth segment 6, there is no gap 7 between two adjacent copper sheets 8. The flexible connecting wire is composed of six connected segments, which can effectively disperse the impact from the generator during operation. The second segment 2, the third segment 3, and the fifth segment 5 are all arc-shaped, and there is a gap 7 between two adjacent copper sheets 8. The gap 7 between the copper sheets 8 can play a role in dispersing stress. During use, especially when frequently bending, the force applied to the flexible connecting wire can be more evenly distributed, thereby reducing local stress concentration, improving fatigue resistance, and extending service life.

[0034] The thickness of each copper sheet 8 is 0.7-0.9mm, and the maximum gap 7 between two adjacent copper sheets 8 is 0.2-0.3mm; this ensures that the strength of each copper sheet 8 is sufficient, and the maximum gap 7 between the copper sheets 8 can ensure that the second segment 2, the third segment 3 and the fifth segment 5 can absorb the bending impact from the relative displacement of the two connecting ends, and better disperse the stress.

[0035] The copper sheet 8 has the same width of 30.5mm at the first segment 1, the second segment 2, the third segment 3, the fourth segment 4, and the fifth segment 5. The sixth segment 6 consists of a first part connected to the fifth segment 5 and a second part away from the fifth segment 5. The width of the first part is 30.5mm, and the end of the second part away from the fifth segment 5 is a semi-circular arc with a radius of 30.5mm. The opening is located on the second part and is an elliptical hole. The elliptical hole facilitates the connection and fixation of the flexible connecting wire.

[0036] The length of the sixth segment 6 is 107.3 mm, and the length of the first segment 1 is 23.3 mm; the distance from the end face of the first segment 1 away from the second segment 2 to the fourth segment 4 is less than the minimum distance from the opening to the fourth segment 4; to avoid the opening being blocked by the first segment 1 and affecting the assembly of the flexible connection wire.

[0037] In use, the flexible connecting wire is easily fixed through the opening in the sixth segment 6, and is electrically connected to the other part through the first segment 1. When the first segment 1 and the sixth segment 6 are electrically connected, when the generator vibrates during operation, the second segment 2 and the fifth segment 5 are quarter-circular arcs, and the third segment 3 is semi-circular arc, which can absorb the impact. In addition, there is a gap 7 between the two adjacent copper plates 8 of the second segment 2, the third segment 3, and the fifth segment 5. The gap 7 between the copper plates 8 can play a role in dispersing stress. During use, especially when frequently bending, the force applied to the flexible connecting wire can be more evenly distributed, thereby reducing local stress concentration, improving fatigue resistance, and extending service life.

[0038] Example 2

[0039] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Each copper sheet 8 has a 0.013mm thick silver plating layer covering both its upper and lower surfaces. This increases the wear resistance of each copper sheet 8, thereby improving its service life. The silver plating also enhances the mechanical strength of the flexible connection wire, making it more durable under frequent movement and vibration.

[0041] Each copper sheet 8 has a silver plating layer with a thickness of not less than 0.1 mm on its side. The five copper sheets 8 are connected together at the first segment 1, the fourth segment 4, and the sixth segment 6 through the silver plating layer on the side of the copper sheets 8. Connecting the first segment 1, the fourth segment 4, and the sixth segment 6 through the silver plating layer improves the strength of the first segment 1, the fourth segment 4, and the sixth segment 6 and extends their service life.

[0042] At the second segment 2, the third segment 3, and the fifth segment 5, the gap 7 between two adjacent copper sheets 8 is filled with liquid metal; the liquid metal can effectively absorb impacts and improve the service life of the flexible connection.

[0043] In use, first, plate the top and bottom surfaces of the five copper sheets 8 with a 0.013mm silver plating layer. Then, bend the five copper sheets 8 and stack them together. Then, connect the first segment 1, the fourth segment 4, and the sixth segment 6 on the sides through the silver plating layer. The silver plating increases the wear resistance of each layer of copper sheet 8, thereby improving the service life of the copper sheet 8. The silver plating can also enhance the mechanical strength of the flexible connection line, making it more durable under frequent movement and vibration.
