[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1-5 As shown, the present invention provides a pure nickel, high-temperature-resistant OK wire, primarily used as a connecting wire in electronic cigarettes. Its structure primarily comprises a wire body 1, a welding piece 2 connected to one end of the wire body 1, and a connector 12 connected to the other end of the wire body. By optimizing the internal structure of the welding piece 2, the OK wire provided in this solution facilitates wire welding and protects the welding position, thereby improving OK wire welding efficiency.

[0025] The structure of the wire 1 is primarily formed by twisting together several pure nickel wires 101, which enhances the overall hardness of the wire 1. Since the pure nickel wires 101 are inherently heat-resistant, this also improves the high-temperature resistance of the wire 1. To further protect the pure nickel wires 101 and prevent electrical leakage, the outer layer of the wire 1 is covered with an insulating layer 8 for further protection.

[0026] In order to allow the OK line to be connected to multiple wires at the same time, a welding piece 2 for welding is connected to one end of the wire body 1 in this solution. All wires that need to be connected to the OK line can be welded to the welding piece 2 to be fixed and conductive.

[0027] The welding member 2 primarily consists of a welding pad 201 and an insulating cover 202. The welding pad 201 is located below the insulating cover 202 and is detachably connected. Because the OK wire needs to be conductive, the center of the upper surface of the welding pad 201 is connected to the pure nickel wire 101 of the wire body 1 for conductivity. A first protective sheath 9 is placed at the junction between the wire body 1 and the welding pad 201 to protect the connection and prevent leakage caused by breakage.

[0028] To facilitate wire soldering, a plurality of solder grooves 3 for placing and soldering wires are provided on the upper surface of soldering pad 201. These grooves 3 are distributed along the outer edge of soldering pad 201 and are electrically connected to the side surfaces of soldering pad 201. The solder grooves 3 are trapezoidal in shape, with the top opening larger than the bottom width. This prevents the wires from shifting and increases the area within the solder grooves 3 for soldering, thus enhancing the stability of the soldering process.

[0029] Before the welding pad 201 is welded, an anti-skid layer 6 is adhered to the lower surface of the welding pad 201, and a protruding part 7 is provided on the lower surface of the welding pad 201 and protrudes downward through the anti-skid layer 6 for clamping fixation. The protruding part 7 can be used to clamp into the surface of a connecting part to fix the position of the welding pad 201, and the friction during connection is increased by the anti-skid layer 6, so as to avoid movement during welding of the wire.

[0030] After the wire is welded on the surface of the welding pad 201, the welding part 2 further protects the welding pad 201 and the wire welding surface by using the insulating cover 202 combined with the welding pad 201. At this time, the insulating cover 202 is sleeved on the outside of the wire body 1 and moves along the length direction of the wire body 1, and a groove 4 is provided at the bottom of the insulating cover 202 for covering the upper surface and the side surface of the welding pad 201. After the wire is welded on the upper surface of the welding pad 201, the groove 4 directly covers the welding pad 201 to protect the position of the wire welding. Correspondingly, in order not to affect the wire leading out from the side surface of the welding pad 201, a plurality of wire holes 5 for leading out the welded wire are provided on the side surface of the groove 4, and the number and position of the wire holes 5 correspond to the welding groove 3.

[0031] When the groove 4 of the insulating cover 202 is connected with the welding pad 201, a plurality of downward protruding insertion columns 10 are arranged in the groove 4 for inserting and fixing the upper surface of the welding pad 201. Correspondingly, a plurality of insertion grooves 11 corresponding to the number and position of the insertion columns 10 are arranged on the upper surface of the welding pad 201, the insertion columns 10 are inserted into the insertion grooves 11 for fixation, and a detachable structure is formed.

[0032] In addition, an electric connection head 12 is connected to the end of the wire body 1 away from the welding part 2 and is in electrical connection with the pure nickel wire 101 of the wire body 1. The electric connection head 12 is provided with an insertion groove 13 for insertion, and a terminal 14 for electrical connection is arranged in the insertion groove 13. A user can directly conduct electricity with an external connection through the plug-in mode during use. A second protective sleeve 15 is further sleeved on the connection part of the wire body 1 and the electric connection head 12 to strengthen the protection of the connection part and prevent breakage.

[0033] Compared with the conventional technology, the technical scheme adds the welding pad 201 for fixing a plurality of wires at one end of the wire 1, the welding pad 201 is provided with a plurality of welding grooves 3 for convenient welding of the wires, and the insulating cover 202 for protecting the surface welding part of the welding pad 201 is further added to protect the welding part. Meanwhile, the anti-skid layer 6 and the protruding part 7 are further added to the bottom of the welding pad 201 to prevent movement of the welding pad 201 during welding and facilitate welding.

[0034] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, no reference signs in the claims being regarded as limiting the claims concerned.
