Unless otherwise specified, the electrical connection connectors, conductors, insulating layers, etc. used in the embodiments of the utility model may be known to those skilled in the art, and the size, shape, etc. of each component are not specifically limited.

[0030] See also Figure 1 and Figure 2 An electrical connection mechanism for a reciprocating motion mechanism includes an electrical connection line 100, a first connection connector 200 and a second connection connector 300, wherein the first connection connector 200 is arranged at one end of the electrical connection line 100, and the second connection connector 300 is arranged at the other end of the electrical connection line 100, and the first connection connector 200 and the second connection connector 300 are both electrically connected to the electrical connection line 100.

[0031] In this embodiment, the first connection connector 200 and the second connection connector 300 are connection connectors known to those skilled in the art, which can be purchased commercially, and their specific structures are not limited or described herein. The first connection connector 200 and the second connection connector 300 can be selected according to the specific usage scenario.

[0032] In this embodiment, the electrical connection line 100 includes a first connection line segment 110, a second connection line segment 120 and a third connection line segment 130 arranged in sequence along its length direction. The first connection line segment 110 is electrically connected to the first connection connector 200, and the second connection line segment 120 is electrically connected to the second connection connector 300.

[0033] In this embodiment, the second connecting wire segment 120 has a first spiral structure as a whole, and the first spiral structure includes a plurality of first spiral turns 121 formed by spirally winding the electrical connecting wire 100 around a first axial direction 001 under high temperature conditions. At least one first spiral turn 121 also has a second spiral structure, and the second spiral structure includes a plurality of second spiral turns 122 formed by spirally winding the electrical connecting wire 100 around a second axial direction 002 under high temperature conditions. The first axial direction 001 and the second axial direction 002 are set at an angle, so that the second connecting wire segment 120 of the electrical connecting wire can be elastically stretched in the first axial direction as a whole, and can be elastically stretched locally in the second axial direction, and during the elastic stretching process, the problem of the internal conductor being broken due to local bending at a large angle will not occur.

[0034] In this embodiment, the first spiral coil 121 is tilted along the first axis direction 001, and the inclination angle of the first spiral coil 121 is 45-60°, preferably 50-60°, so that the multiple first spiral coils 121 in the electrical connection line can swing along the first axis direction as a whole when stretched, thereby improving the tensile and fatigue resistance of the electrical connection line.

[0036] In this embodiment, the second spiral coil 122 is tilted along the second axis direction 002, and the inclination angle of the second spiral coil 122 is 45-60°, preferably 50-60°, so that the multiple second spiral coils 122 in the electrical connection line can swing along the second axis direction as a whole when stretched, thereby improving the tensile and fatigue resistance of the electrical connection line.

[0037] In this embodiment, the inner diameter of the second spiral coil 122 is 3-5 mm.

[0038] It should be noted that the second spiral structure can be a part of the first spiral turn, or the first spiral turn as a whole has the second spiral structure. Of course, the second spiral structure can be arranged on one or several of the first spiral turns, and can be arranged in the same area or different areas on multiple first spiral turns at the same time.

[0039] In this embodiment, the angle between the first axis direction 001 and the second axis direction 002 is 45-60°.

[0040] In this embodiment, the ratio of the length of the electrical connection line 100 of the first connecting line segment 110, the second connecting line segment 120 and the third connecting line segment 130 is (4-5): (25-27): (4-5). For example, a black electrical connection line with a length of 350 mm has a length of 45+ / 5 mm reserved at both ends, and the middle length is wound into a spring shape with a 5-turn spiral structure, and the diameter of each turn is 13mm+ / -1mm. The extension length of the second connecting line segment is controlled to be 110mm+ / -10mm.

[0041] See also Figure 3 The electrical connection line 100 includes a plurality of wires 10 and a first insulating layer 20, the wires 10 include a conductor 11 and a second insulating layer 12, the second insulating layer 12 is compressed and wrapped around the outside of the plurality of conductors 11, the plurality of wires 10 are arranged in parallel, and the first insulating layer 20 is compressed and wrapped around the outside of the plurality of wires 10, or the wires 10 include a plurality of conductors 11, an insulating sleeve and a second insulating layer 12, the plurality of wires 10 are arranged in parallel, the insulating sleeve is wrapped around the outside of the plurality of wires 10, and the second insulating layer 12 is wrapped around the outside of the insulating sleeve.

[0042] In a specific implementation case, if Figure 3 As shown, the plurality of wires 10 are arranged in a linear structure, and the cross-section of the electrical connection line is flat. Alternatively, in another specific implementation case, the plurality of wires 10 are combined to form n wire groups, the first wire group includes one wire, and the one wire contained in the first wire group is arranged in the central area of ​​the electrical connection line, and any of the remaining wire groups includes multiple wires, and the multiple wires contained in any of the remaining wire groups are distributed in a circular area, and the circular area is concentrically arranged with the central area, and the second wire group to the nth wire group are arranged in sequence along the radial direction of the electrical connection line, and a soft insulating filling structure is also arranged between the n wire groups.

[0043] For example, the number of conductors 11 can be 19, the diameter of each conductor 11 is 0.08 mm, the material is tinned copper, the material of the second insulating layer 12 is PP material, the conductor 11 and the second insulating layer 12 can be extruded by an injection molding machine, and 4 wires 10 of different colors are extruded side by side to form a flat wire. The material of the first insulating layer 20 can be TPU, etc., the wire 10 and the first insulating layer 20 can be extruded by an injection molding machine, the insulating sleeve can be a paper sleeve, and the soft insulating filling structure can be cotton filling, etc.

[0044] In this embodiment, the electrical connection mechanism also includes a flexible support body, the second connecting wire segment 120 is arranged on the support body, the first spiral circle 121 can be formed by the second connecting wire segment 120 being wound on the support body, and at least the surface of the part of the support body that contacts the second connecting wire segment 120 is smooth.

[0045] In this embodiment, the surface of the support body has a plurality of limit grooves arranged along its axial direction, and the plurality of limit grooves are smoothly connected to form a spiral structure matching the second connecting line segment 120, and each of the first spiral turns 121 is correspondingly arranged in a limit groove, and the width of the limit groove in the first axial direction 001 is greater than the width of the first spiral turn 121, and the surface of the fiber groove is smooth, so that the electrical connecting line can move a certain distance in the limit groove.

[0046] In this embodiment, the support body may be a flexible plastic corrugated tube with a spiral limiting groove on the surface.

[0047] Specifically, the stress on the electrical connection wire is related to the elastic coefficient K and the outer diameter of the spiral coil. In other words, the elastic coefficient is inversely proportional to the outer diameter of the spiral coil. The smaller the outer diameter, the greater the elastic coefficient. According to Hooke's law: F = K·X

[0048] X is the stretched length of the electrical connection wire, that is, the longer the stretched length of the electrical connection wire is, the greater the stress it is subjected to. Within the theoretical deformation range of the electrical connection wire, the stretching of the electrical connection wire can be performed infinitely. The deformation range of the electrical connection wire depends on: the number of spiral turns and the material properties of the electrical connection wire itself. At the same time, the stretched length of the electrical connection wire is related to its own stretching angle, that is, the larger the stretching angle of the electrical connection wire is, the longer its stretched length is, and the greater the stress generated is.

[0049] In actual use, the stretching angle of the electrical connection line is between 45° and 60°. When the stretching angle is appropriate, a more uniform distribution of stress on the cable can be achieved, reducing local stress concentration, so as to better meet the requirements of reciprocating equipment for cable connection in special environments. At the same time, a suitable stretching angle of the electrical connection line can reduce fatigue damage under cyclic loading during the use of reciprocating equipment. A reasonable stretching angle can also slow down the expansion of cracks caused by fatigue during the use of the equipment and extend the service life of the connector. In addition, a suitable stretching angle can also make the spring structure deform better when subjected to force, thereby improving the overall elastic performance.

[0050] In daily production practice, the solution provided by this case is a better solution for reciprocating equipment when traditional wiring cannot better adapt to current use requirements. Compared with traditional wiring, the electrical connection mechanism provided in this implementation case has a simpler structure, is easy to design and manufacture, and can provide a certain elastic transmission in the use of reciprocating equipment, reduce the fatigue of the electrical connection mechanism, reduce maintenance and use costs, and better alleviate fatigue damage caused by impact under vibration and impact in the use environment.

[0051] An embodiment of the utility model provides an electrical connection mechanism for a reciprocating motion mechanism, which can be extended and retracted in its own length direction, thereby greatly reducing the occupied space volume in the cloth cutting machine, and making the reciprocating stretching life of the electrical connection mechanism reach more than 1.1 million times, which can effectively increase the use time of the product, reduce the number of replacements, and improve work efficiency.

Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the utility model.
