[0030] Please refer to Figures 1 to 3 It shows the specific structure of the preferred embodiment of the utility model, which is a headset wire connecting device.

[0031] Among them, part of the wire 40 is bent in the storage cavity 16 after coming out of the wiring slot 14. When the sound unit 30 is pulled out, the bent part of the wire 40 is pulled out of the storage cavity 16, and when the sound unit 30 is retracted, the bent part of the wire 40 is stored in the storage cavity 16. This design does not need to thermoplastically shape the wire 40, shortens the production time and reduces the manufacturing cost.

[0032] The application provides a headset wire 40 connecting device, which comprises a head beam 10, the end of the head beam 10 is provided with a slide rod 11, the slide rod 11 is provided with a wire groove 14 and a receiving cavity 16, a slide rod shell 17 is slidably arranged on the slide rod 11, an earphone support 20 is connected with the slide rod shell 17 and a sound unit 30, the wire 40 passes through the wire groove 14 and the earphone support 20 and is connected with the sound unit 30, and part of the wire 40 is bent in the receiving cavity 16. The head beam 10 is made of plastic material, and an elastic steel belt can be arranged in the head beam 10 to enhance the elasticity. The wire 40 passes through the head beam 10 and is then connected with the two sound units 30. The slide rod shell 17 can slide up and down on the slide rod, so that the position of the sound unit 30 can be adjusted. The wire 40 passes out of the wire groove 14 and then forms a bending section, and the bending section is in the receiving cavity 16. The bending curvature of the wire 40 is very small, that is, the bending degree is very small, and the wire 40 can not be damaged by repeated bending. When the sound unit 30 is pulled out, the bending section of the wire 40 is pulled out of the receiving cavity 16, and when the sound unit 30 is retracted, the bending section of the wire 40 is received into the receiving cavity 16. This design does not need to heat the wire 40 to shape, shortens the production time and reduces the manufacturing cost. In addition, this design also avoids large-angle bending of the wire 40, which helps to improve the service life of the wire 40. During the extension and retraction of the sound unit 30, the wire 40 is limited by the wire groove 14, so that the wire 40 will not rub against the inner wall of the slide rod shell 17, and the mute effect is better. Compared with the current mainstream design in the market, the innovative design effectively reduces the bending degree of the wire 40 and the bending movement stroke of the separated wire when the upper and lower covers of the slide rod 11 are extended and retracted, thereby reducing the friction with the slide rod shell 17, and the comfort and experience are better.

[0033] Preferably, the first section of the wire groove 14 is arranged on the right side of the slide rod 11, the second section of the wire groove 14 is arranged on the inner side of the slide rod 11, and the two sections of the wire groove 14 are connected together. The end of the second section of the wire groove 14 is provided with a wire outlet 15, and the wire outlet 15 faces the receiving cavity 16. The two ends of the wire groove 14 are matched to help limit the position of the wire 40, and this design can prevent the wire 40 from loosening and has a good fixing effect. After the wire 40 passes out of the wire outlet, part of the wire 40 is bent in the receiving cavity 16, and the curvature of the part of the wire 40 is very small, which can prevent the wire 40 from being damaged.

[0034] Preferably, the shape of the wire 40 in the receiving cavity 16 is one of a circular arc, an elliptical arc and a parabola. The above shapes can smoothly pull the wire 40 out of the receiving cavity 16, and when the sound unit 30 is retracted, part of the wire 40 can be returned to the receiving cavity 16 and restored to a bent shape under the action of the receiving cavity 16. This design does not need to pre-shape the wire 40, which saves a complex process and helps to reduce the manufacturing cost and production efficiency.

[0035] Preferably, the inner side of the slide rod 11 is provided with a spring piece 12, the inner wall of the slide rod shell 17 is provided with a limiting tooth 18, and the spring piece 12 is pressed against the limiting tooth 18. The spring piece 12 and the limiting tooth 18 cooperate to limit the self-sliding between the slide rod 11 and the slide rod shell 17, that is, the sliding needs to be under the action of external force. This structure is very ingenious and simple.

[0036] Preferably, the inner wall of the slide rod shell 17 is provided with a baffle 19, and the slide rod 11 is provided with a limiting block 13 which can be stopped by the baffle 19. When the slide rod shell 17 slides to the maximum stroke on the slide rod 11, the limiting block 13 is stopped by the baffle 19, and this design can prevent the slide rod shell 17 from falling off.
