Moreover, the braided wires used for the laps are inevitably limited by the material properties and the production process, which leads to some defects that limit the reliability of the braided sleeve laps.

[ detailed description ] A
The following examples are further illustrative and supplementary to the present invention and do not limit the present invention in any way.
As shown in fig. 1 to 3, the flexible bonding wire of the present invention includes a main body 20 of a lead 201 and a crimp terminal 10. The crimp terminal 10 is used for quick installation, and is connected to both ends of the main body 20 of the wire 201.
As shown in fig. 1, the crimp terminal 10 is made of a metal material, and the structure thereof can be referred to a known technique. In the present embodiment, the crimp terminal 10 is provided with a through hole 11 for fixedly attaching the crossover to a place of use through a bolt, a screw, or the like.
As shown in fig. 1 to 3, the main body 20 of the lead 201 is used for conductive connection, and includes a twisted wire portion 21 and a spring wire portion 22. The spring wire portions 22 are distributed between two adjacent twisted wire portions 21. The spring wire portion 22 may promote flexibility of the body 20 of the lead 201 such that the body 20 of the lead 201 is easily free to bend. The lengths of the spring wire portions 22 and the twisted wire portions 21 may be set as necessary.
The twisted wire portion 21 is formed by twisting a plurality of strands of wires 201, and the number of the wires 201 may be set as required. In this embodiment, the twisted wire portion 21 is formed by twisting 6 conductive wires 201, and has a circular cross section. The thickness of the lead 201 can be selected as desired. The outer surface of the lead 201 is an insulating sheath, the inner part of the lead is a conductive wire, and in the embodiment, the inner part of the lead is formed by twisting a plurality of guide wires with the diameter of about 0.1 mm. The guide wire can be made of copper, copper alloy, aluminum alloy, nickel alloy and other metal wires.
The spring wire portion 22 is formed in a spring wire structure by winding the conductive wire 201 of the twisted wire portion 21 in the circumferential direction. In other words, with the wire 201, the main body 20,6 wires 201 are continuous, twisted with each other at some positions to form the twisted wire portion 21, and wound in the circumferential direction at some positions to form the spring wire portion 22.
In order to maintain the flexibility of the spring wire portion 22 and prevent the wire 201 of the spring wire portion 22 from being pulled out and affecting the use, an insulating hollow tube 202 is provided at the center of the twisted wire portion 21 and the spring wire portion 22.
The hollow tube 202 is made of a high-strength insulating material, and is flexible and bendable. The diameter of the hollow tube 202 may be set as desired.
The stranded conductor 201 of the stranded part 21 is stranded on the periphery of the hollow tube 202, so that the hollow tube 202 is enclosed in the stranded part 21. In the twisted portion 21, the wire 201 is in close contact with the hollow tube 202.
The plurality of strands of wires 201 of the spring wire portion 22 are wound along the outside of the hollow tube 202 to form a spring wire, thereby enclosing the hollow tube 202 within the spring wire portion 22. Within the spring wire portion 22, a hollow tube 202 is spaced from the wire 201.
The length of the hollow tube 202 is the same as the length of the main body 20 of the lead 201, and both ends of the hollow tube are flush with both ends of the main body 20 of the lead 201.
A pull wire 203 is arranged in the hollow tube 202. The pull wire 203 is made of a high-strength material, for example, a titanium alloy wire. The pulling wire 203 is used to increase the binding force in the spring wire portion 22, and to pull both ends of the spring wire to prevent the wires 201 of the spring wire portion 22 from being scattered. The pull wire 203 is used for double protection.
Further, the pull wire 203 is disposed at the hollow tube 202 in the spring wire portion 22. In other words, at the hollow tube 202, at a position corresponding to the twisted wire portion 21, the pull wire 203 is not provided. A pull wire 203 is provided at a position corresponding to the spring wire portion 22. The number of the pull wires 203 is the same as that of the spring wire portions 22.
Two ends of the pull wire 203 are fixedly connected with the hollow pipe 202 respectively. For example, a through hole may be formed at the corresponding position of the hollow tube 202, and the pull wire 203 may be pulled and tied at the through hole of the hollow tube 202, so that the pull wire 203 may be fixedly disposed in the hollow tube 202. The length of the post-knotted string 203 is equal to the length of the spring wire portion 22.
Since the plurality of wires 201 are twisted with each other at the twisted wire portion 21 and are wound around the spring wire portion 22 in the circumferential direction, in order to prevent the wires 201 at the transition portion from being unraveled, a fixing portion for preventing the wires 201 from being unraveled is provided at a joint portion where the twisted wire portion 21 and the spring wire portion 22 are joined.
In some embodiments, the fixing portion is an insulating glue, which bonds the wires 201 and the hollow tube 202 at the joint portion together, so that the wires 201 at the two ends of the twisted wire portion 21 are bonded without loosening, thereby facilitating the further winding of the wires 201 to form the spring wire portion 22.
In some embodiments, the fixing portion is an insulating ferrule, which is sleeved on the periphery of the multi-strand wires 201 at the combining portion, and can tightly clamp the multi-strand wires 201 at the combining portion, so as to prevent the wires 201 at the two ends of the twisted wire portion 21 from being loosened, thereby facilitating the wires 201 to be further wound to form the spring wire portion 22.
For the main body 20 of the conducting wire 201, the plurality of conducting wires 201 at the twisted wire part 21 are relatively difficult to loosen, and the fixing part is arranged to fix the conducting wires 201 at the two ends of the twisted wire part without loosening; the plurality of wires 201 at the spring wire portion 22 form a spring wire structure, the plurality of wires 201 are relatively loose, but because the hollow tube 202 is arranged in the spring wire portion 22, and the hollow tube 202 is relatively fixed with the wires 201 in the twisted wire portion 21, the hollow tube 202 restrains the whole length of the spring wire portion 22, so that the wires 201 at the spring wire portion 22 do not scatter along the length direction, but only swing along with the flexible hollow tube 202, thereby improving the flexibility of the wire 201 main body 20, and enabling the wire 201 to freely bend towards any direction. The pull wire 203 arranged in the hollow tube 202 can provide secondary protection for the spring wire part 22, so that the restraint degree in the spring wire part 22 can be improved, and the spring wire part 22 is prevented from being scattered when the hollow tube 202 is damaged. Thus, the conducting wire 201 of the spring wire part 22 is difficult to scatter under the double guarantee of the hollow tube 202 and the pull wire 203, and the spring wire part 22 is prevented from being elongated to influence the use, so that the spring wire part 22 can not only keep the flexibility advantage of the spring wire, but also meet the use requirement of the use place.
Furthermore, a plurality of heat dissipation holes can be arranged on the hollow tube 202, so that the heat of the lead 201 can escape.
Although the present invention has been disclosed in the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
