[0024] The headphone cable welding jig comprises an integrated plate 1, wherein the integrated plate 1 is vertically penetrated with a plurality of through holes 8 having the same number as the distribution cables, and the outer wall of the integrated plate 1 is rotatably connected with two sets of outer frames 3 through two sets of convex shafts 10, and the tops of the two sets of outer frames 3 are fixedly connected with elastic strips 4, and the back surfaces of the two sets of elastic strips 4 are fixedly connected with two sets of holding rings 6, and a positioning component for cable positioning is arranged between the opposite surfaces of the two sets of elastic strips 4;

[0025] The operator passes the thumb and index finger of one hand through the two groups of holding rings 6, then stretches the two groups of elastic strips 4 outward, places the end of the headphone cable downward between the two groups of elastic strips 4, resets the two groups of elastic strips 4, and the clamping blocks 7 on the outer walls of the two groups of elastic strips 4 abut against the outer wall of the headphone cable body, thereby achieving local positioning of the headphone cable. The operator then uses the other hand to pass the multi-component cable through the multiple groups of perforations 8 in sequence until the ends of the multi-component cable to be welded are all placed under the integrated disk 1, and then moves the welding jig and the cable as a whole, and after applying flux to the ends of the multi-component cable at the same time, the ends of the multi-component cable are simultaneously contacted with the tin liquid inside the tin furnace, thereby realizing the welding of the multi-component cables at the same time. The integrated disk 1 and the corresponding number of perforations 8 make the ends of each component cable have an independent area, thereby avoiding series welding, thereby improving the welding efficiency of the headphone cable.

[0026] Specifically, Figure 2 and Figure 4As shown, the outer wall of the convex shaft 10 is fixedly connected with a convex ring 11, and the convex ring 11 and the outer wall of the convex shaft 10 are rotatably connected with the inner wall of the outer frame 3, providing the outer frame 3 with axial deflection characteristics while preventing the outer frame 3 from completely separating from the convex shaft 10. One of the two groups of outer frames 3 is fixedly connected with a fixing sleeve 12 on the outer wall, and the inner wall of the fixing sleeve 12 abuts against the outer wall of the convex shaft 10, and a fixing part for locking the position of the outer frame 3 is arranged on the outer side of the fixing sleeve 12, and the fixing part includes a positioning rod 9, and the outer wall of the positioning rod 9 is screwed and connected with the inner wall of the fixing sleeve 12, and the open end of the positioning rod 9 abuts against the outer wall of the convex shaft 10, and the open end of the positioning rod 9 is wrapped with a rubber sleeve, The distributed holding ring 6 and the integrated disk 1 realize the positioning of the cable while avoiding the obstruction of the line of sight when the cable is combined with the through hole 8. At the same time, the outer frame 3 can be deflected. The inner wall of the outer frame 3 rotates and cooperates with the convex ring 11, and the fixing sleeve 12 rotates and cooperates with the convex shaft 10. Until the misalignment angle of the holding ring 6 and the integrated disk 1 reaches a suitable range, the positioning rod 9 is rotated to make it screwed with the inner wall of the fixing sleeve 12 until the open end of the positioning rod 9 abuts against the outer wall of the convex shaft 10, thereby achieving the position locking of the outer frame 3 and the convex shaft 10 through friction, so that the misalignment angle between the holding ring 6 and the integrated disk 1 can be adjusted accordingly according to the usage requirements.

[0027] Specifically, Figure 2 and Figure 3 As shown, guide sleeves 2 are provided on the tops of the multiple groups of through holes 8, and the bottoms of the multiple groups of guide sleeves 2 are fixedly connected to the tops of the integrated disks 1, so as to expand the depth of the through holes 8 and ensure the stability of the cable connection. A frame 5 is fixedly connected between the two groups of elastic strips 4, so as to connect the two groups of elastic strips 4 in series and provide a support for the cable body. The positioning assembly includes two groups of clamping blocks 7, which are fixedly connected to the two groups of elastic strips 4 respectively, and the two groups of clamping blocks 7 are both in an arc-shaped structure, which open the two groups of elastic strips 4 outward, place the end of the headphone cable downward between the two groups of elastic strips 4, reset the two groups of elastic strips 4, and the clamping blocks 7 on the outer walls of the two groups of elastic strips 4 abut against the outer wall of the headphone cable body, so as to achieve local positioning of the headphone cable.

Then the operator uses the other hand to pass the multi-component cable through the multiple groups of perforations 8 in sequence until the ends of the multi-component cable to be welded are placed under the integrated disk 1, then moves the welding jig and the cable as a whole, and after applying flux to the ends of the multi-component cable at the same time, the ends of the multi-component cable are simultaneously exposed to the tin liquid inside the tin furnace, thereby realizing the welding of the multi-component cable at the same time, through the integrated disk 1 and the corresponding number of perforations 8. The ends of each group of cables have independent areas, avoiding series welding, thereby improving the welding efficiency of the headphone cables. The staggered holding ring 6 and integrated disk 1 realize the positioning of the cables and avoid line of sight obstruction when the cables are combined with the perforations 8. At the same time, the outer frame 3 can be deflected, and the inner wall of the outer frame 3 rotates with the convex ring 11 while the fixing sleeve 12 rotates with the convex shaft 10 until the misalignment angle of the holding ring 6 and the integrated disk 1 reaches a suitable range. The positioning rod 9 is rotated to screw it with the inner wall of the fixing sleeve 12 until the open end of the positioning rod 9 abuts against the outer wall of the convex shaft 10, thereby achieving position locking of the outer frame 3 and the convex shaft 10 through friction, so that the misalignment angle between the holding ring 6 and the integrated disk 1 can be adjusted accordingly according to usage requirements.
