Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a swing-resistant wire material connection structure and a rotating tail frame with the structure. Background Art
[0002] The hair straightener heats the heating element or heating wire of the hair straightener by electric current and transmits the heat to the aluminum plate or ceramic plate, which is used to clamp the hair to straighten or curl the hair. The current hair straightener is usually provided with a rotating tail inner frame, as shown in Chinese patent CN201921361152.9, which discloses a rotating tail inner frame for a hair straightener. The power cord is directly riveted to the terminal of the rotating tail inner frame to power the hair straightener.
[0003] Since the hair straightener needs to rotate frequently during curling, the power cord at the rear end will also be subjected to a large torsional force. Therefore, this type of power cord needs to meet a certain number of swing test requirements. However, during the swing test, the connection between the cable and the terminal will be directly affected, making the wire core at the riveted position with the terminal easy to loosen or break, making it difficult to meet the swing test requirements.

[0010] Furthermore, an inner end of the mounting hole is equal to or smaller than an inner diameter of the terminal.
[0011] Furthermore, the limiting portion is integrally formed on the terminal.

[0013] Furthermore, a guide section is arranged in the installation hole, and the aperture of the guide section is gradually reduced from the outside to the inside.
[0014] Furthermore, a limiting segment is arranged outside the guide segment, and the inner diameter of the limiting segment is consistent with the outer diameter of the wire.

Because the wire core is composed of a plurality of thin metal wires, this structure is set so that the force during the swing will not directly act on the wire core of the wire, thus avoiding the problem of the wire core loosening or breaking, greatly improving the service life of the cable, and enabling the cable to pass strict swing test requirements.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] like Figures 1 to 4 As shown, the utility model provides a hairdressing tool swivel, which includes a cable 10, a swivel frame 20 and an insulating layer 30. One end of the cable 10 is riveted to the swivel frame 20, and the insulating layer 30 is wrapped around the connection position between the cable 10 and the swivel frame 20. The cable 10 includes an insulating outer layer 11 and two wires 12 arranged in the insulating outer layer 11. It can be understood that the wires 12 can also be more than two, and the number is not limited here.
[0027] The rotating tail frame 20 includes an insulating portion 21, a plug connector 22, a terminal 23 and a limiting frame 24. The plug connector 22 and the terminal 23 are both made of metal materials. The plug connector 22 and the terminal 23 extend in opposite directions, and the inner ends of the two are in contact and electrically connected. In this embodiment, the number of the terminals 23 is two arranged side by side. The insulating portion 21 and the limiting frame 24 are both made of insulating materials. More specifically, in this embodiment, the materials of both are plastic materials. The insulating portion 21 is wrapped around the outer surface of the junction of the plug connector 22 and the terminal 23, and the limiting frame 24 is arranged on the end surface of the insulating portion 21 on one side of the terminal 23.
[0028] The limiting frame 21 includes a connecting portion 211 and a limiting portion 212, and the limiting portion 212 is connected to the insulating portion 21 through the connecting portion 211. The connecting portion 211 is arranged between the two terminals 23 and is spaced apart from the two terminals 23. Two mounting holes 213 are arranged on the limiting portion 212, and the aperture of the mounting hole 213 is gradually reduced from the outer end to the inner side, so as to guide the wire 12 and facilitate the embedding of the wire 12. In addition, a limiting section 215 is also arranged on the outer side of the mounting hole 213, and the hole wall of the limiting section 215 is arranged vertically. The inner diameter of the limiting section 215 is equal to or slightly larger than the outer diameter of the wire 12, and it is used to limit the wire 12 so that the wire 12 in the mounting hole 213 cannot shake.
[0029] The limiting portion 212 is provided with a limiting hole 214 on one side end surface of the terminal 23, the outer end of the terminal 23 is embedded in the limiting hole 214, and the inner end of the mounting hole 213 is equal to or smaller than the inner diameter of the terminal 23. In this embodiment, the terminal 23 is a riveted terminal. It can be understood that in other embodiments, the terminal 23 and the wire 12 can also be connected by welding. This is not limited here.
[0030] When in use, the insulation layer of the wire 12 is stripped to expose the wire core, and the wire core is inserted from the outer end of the mounting hole 213 of the limiting portion 212, and the wire core extends into the terminal 23. The wire 12 without the insulation layer stripped is embedded in the mounting hole 213, and the mounting hole 213 protects and limits it to prevent the inner end of the wire 12 from shaking. Finally, the terminal 23 is riveted to fix the wire core in the terminal 23.
[0031] In summary, the utility model sets a limit frame 24 on the outside of the terminal 23, and the limit frame 24 protects and limits the outside of the connection end between the cable 10 and the terminal, so that when the cable is subjected to a swing test, the limit portion 212 can protect the end of the wire 12. Because the wire core is composed of a plurality of fine metal wires, this structure is set so that the force during the swing will not directly act on the wire core of the wire 12, avoiding the problem of the wire core being loose or broken, so that the cable can pass the strict swing test requirements. The utility model is highly practical and has a strong promotional significance.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
