[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a lightweight, high-strength automotive terminal lead wire, comprising a copper ring 1, a lead wire 3 above the copper ring 1, and a fixing mechanism 2 between the lead wire 3 and the copper ring 1.

[0025] Specifically, by Figure 2-5The fixing mechanism 2 includes a vertical cylinder 201 fixed to the top of the copper ring 1. A limiting ring 202 is fixedly connected inside the vertical cylinder 201. The bottom end of the lead wire 3 passes through the limiting ring 202 and extends into the interior of the vertical cylinder 201. A copper sheet 207 located inside the vertical cylinder 201 is fixedly connected between the limiting ring 202 and the copper ring 1. The copper sheet 207 has a through groove 209. The lead wire 3 passes through the through groove 209 and is in contact with the copper sheet 207. An inner plate 2010 is fixedly connected inside the vertical cylinder 201. Two connecting posts 2017 are symmetrically fixedly connected to the outer side of the inner plate 2010. The copper sheet 207 is located between the two connecting posts 2017. A clamping plate 2015 is movably sleeved between the two connecting posts 2017. The clamping plate 2015 is in contact with the lead wire 3. A fixed rod is fixedly connected to the side of the copper sheet 207 away from the inner plate 2010. The fixed plate 2016 and the two connecting posts 2017 are fixedly connected to the fixed plate 2016 at the ends away from the inner plate 2010. The fixed plate 2016 is sleeved on the outside of the lead wire 3. The top of the inner plate 2010 is rotatably connected to the lead screw 2012. The top of the lead screw 2012 is fixedly connected to the turntable 2013. The lead screw 2012 passes through the limiting ring 202 and is rotatably connected to the limiting ring 202. The outside of the lead screw 2012 is threaded with the nut 2011. The side of the nut 2011 near the copper sheet 207 is rotatably connected to the movable rod 2014. The end of the movable rod 2014 away from the nut 2011 is rotatably connected to the clamping plate 2015. The inside of the vertical cylinder 201 is provided with a sliding groove 208. The nut 2011 is slidably connected to the sliding groove 208. The side of the vertical cylinder 201 is provided with a side groove to facilitate the operation of the lead wire 3.

[0026] In use, first, the lead wire 3 is passed through the limiting ring 202 and the through groove 209 and bent to fit against both sides of the copper sheet 207. At the same time, the fixing plate 2016 is fitted on the outside of the lead wire 3. Then, the turntable 2013 is rotated, which drives the lead screw 2012 to rotate and drives the lead nut 2011 to slide down along the slide groove 208. Then, the movable rod 2014 drives the clamping plate 2015 to slide along the two connecting posts 2017 until the clamping plate 2015 clamps and fixes the lead wire 3. The copper ring 1 under the copper sheet 207 can be fixedly connected to the external terminal, so that the signal of the lead wire 3 can be transmitted to the external device. When the turntable 2013 is rotated in the opposite direction, the clamping plate 2015 slides along the two connecting posts 2017 and moves away from the lead wire 3, releasing the fixation of the lead wire 3. Finally, the lead wire 3 is removed.

[0027] Specifically, by Figure 2-3 As shown, a screw cylinder 205 is sleeved on the outer side of the vertical cylinder 201, and a rubber sleeve 203 is fixedly sleeved on the outer side of the screw cylinder 205. Multiple auxiliary grooves 204 are provided at equal angles on the outer side of the rubber sleeve 203. The auxiliary grooves 204 facilitate the rotation of the rubber sleeve 203. An external thread 206 is provided on the outer side of the vertical cylinder 201, and the screw cylinder 205 is threaded onto the outer side of the vertical cylinder 201 through the external thread 206.

[0028] In use, first, put the screw 205 on the outside of the vertical cylinder 201 and rotate it until the screw 205 wraps around the vertical cylinder 201. At this time, the rubber sleeve 203 is installed on the outside of the vertical cylinder 201 to protect the terminal, play a buffering role, and finally improve the strength of the terminal.
