[0002] Retractable wire boxes are products that people often use in their daily lives. They can help people organize redundant wires, save space, and keep the wires tidy. The currently used retractable wire boxes connect two wires to the conductive track through contacts. For example, Chinese utility model patent 2007201950149 discloses an automatic headphone wire retracting device. Figure 1 As shown, a plurality of gradually increasing circular conductive tracks are fixedly provided on the inner circle of the winding box, and the welding points are electrically connected to the conductive tracks one by one; a coil spring is provided on the periphery of the reel, and the coil spring drives the winding box to rotate; a bracket is fixed at one end of the reel, and a sliding contact is provided on the bracket, and the lead wire of the sliding contact is led out along the bracket to receive the audio signal. The telescopic wire box using this technology has a small electrical contact area, and the signal and current transmission stability between the contact and the conductive track is not good enough, which affects normal use. Long-term use is prone to carbon deposits on the conductive track, resulting in poor product contact and poor guiding effect, which affects the service life of the product. To this end, a telescopic wire box with high reliability and stable contact is proposed to solve the above problems. Utility Model Content

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] In order to solve the problems of the existing telescopic wire box using contacts to contact the conductive track, resulting in easy carbon deposition on the conductive track, poor contact, poor guiding effect, short service life, etc., the utility model provides a telescopic wire box with high reliability and stable contact, such as Figure 2-10 As shown, it specifically includes a wire box, an electric wire 4, a rotatable lower disk 5 is provided in the wire box, the electric wire 4 is coiled on the lower disk 5, and the lower disk 5 is installed with an electric shock module 3, the electric shock module 3 includes a central axis 31, a first rotating plate 32, a fixed guide plate 36 and a rotating guide plate 37, the fixed guide plate 36 is abutted against the rotating guide plate 37, the rotating guide plate 37 is electrically connected to the electric wire 4 coiled on the lower disk 5 through a moving conductor 371, the fixed guide plate 36 is electrically connected to another electric wire 4 through a fixed conductor 361, and the lower disk 5 is clamped with the first rotating plate 32 through the notch 372 of the first rotating plate 32.

[0026] like Figure 3 , 5 As shown, a coil spring 6 for winding the line and a button 8 for controlling the coil spring 6 are provided below the lower disc 5 to realize automatic winding of the line.

[0027] like Fig. 9As shown, a spring sheet 38 is further provided between the fixed guide piece 36 and the rotating guide piece 37, and the fixed guide piece 36 abuts against and is electrically connected to the rotating guide piece 37 through the spring sheet 38, so that the fixed guide piece 36 and the rotating guide piece 37 rotate more smoothly and fit closely. It should be noted that the fixed guide piece 36 can also be designed as an undulating ring shape and be in elastic contact with the rotating guide piece 37 to ensure that they can still fit closely after long-term use and reduce friction to facilitate rotation.

[0028] like Figure 6 , 7 As shown in Figures 8 and 9, in this embodiment, the electric shock module 3 includes three contact modules, each of which is provided with a fixed guide 36 and a rotating guide 37. The first contact module 320, the second contact module 330, and the third contact module 340 are separated by a second rotating plate 33 and a third rotating plate 34. The top of the third module is also provided with an upper plate 2, as shown in Figures 8 and 9. Fig.10 As shown, the upper plate 2, the first rotating plate 32, the second rotating plate 33, the third rotating plate 34, the fourth rotating plate 35 and the lower plate 5 are connected by the connecting column 9 to realize synchronous rotation. It should be noted that the electric shock module 3 can be equipped with more than two contact modules, each of which is provided with a fixed guide 36 and a rotating guide 37, and the fixed wire 361 of the fixed guide 36 passes through the central axis 31 and is electrically connected to the external wire 4.

[0031] In actual use, Figure 4 As shown, the moving conductors 371 of all rotating guides 37 are electrically connected to the wires 4 wound on the lower plate 5, and all fixed guides 36 are electrically connected to another wire 4 through the fixed conductors 361. When the wound wire 4 is pulled out, the upper plate 2, the first rotating plate 32, the second rotating plate 33, the third rotating plate 34, and the lower plate 5 in the electric shock module 3 are also driven to rotate, and the coil spring 6 is tightened at the same time. During this process, the fixed guide 36 and the wire electrically connected to the fixed guide 36 remain stationary, but the wire is always electrically connected to the wound wire 4 through the fixed guide 36 and the rotating guide 37. In summary, the utility model changes from a point-to-surface contact mode to a surface-to-surface contact mode, with a larger contact area, which effectively overcomes the problems of carbon deposition, poor contact, and poor guiding effect.
