[0005] A positioner for connecting wire welding includes a bottom plate. One end of the bottom plate is provided with an end plate. An upper end opening of the end plate is formed with a U-shaped groove, which plays a role in limiting the insertion pins, and it is also convenient to take out the connecting wire and the pins after the connecting wire welding is completed.

[0006] The other end of the bottom plate is provided with an outer plate. A pair of movable through rods are inserted through the outer plate. An outer pull plate is provided at the outer end of the movable through rod, and a positioning push plate is provided at the inner end of the movable through rod.

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Figure 2 Shows the enlarged view of A.

[0018] Figure 3 Shows the three-dimensional structure of one of the embodiments Figure 2 . DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] As Figures 1 to 3 shown, a positioner for welding connecting wires includes a bottom plate 1. One end of the bottom plate 1 is provided with an end plate 10, and a U-shaped groove 11 is formed in the upper end of the end plate 10 in an open manner.

[0020] At the other end of the bottom plate 1, there is an outer plate 12. A pair of movable through rods 2 are inserted through the outer plate 12. At the outer side end of the movable through rod 2, there is an outer pull plate 20. At the inner side end of the movable through rod 2, there is a positioning push plate 21. At both ends of the positioning push plate 21, there are positioning clamping plates 22. A spring 23 is sleeved on the movable through rod 2. The spring 23 is located between the positioning push plate 21 and the outer plate 12. There is a convex plate 24 on the outer plate 12. At the outer side end of the convex plate 24, a V-shaped plate 25 is rotatably arranged. The V-shaped plate 25 is located outside the outer pull plate 20. There is a handle 26 on the V-shaped plate 25.

[0021] On the outer wall of the end plate 10, there is a clamping backing plate 3. On the upper wall of the clamping backing plate 3, there are multiple positioning blocks 30. There are multiple vertical rods 32 on the clamping backing plate 3. A pressing block 4 is sleeved on the vertical rods 32. Inside the pressing block 4, there are multiple partition plates 31. The partition plates 31 are located between adjacent two positioning grooves 40. On the lower wall of the pressing block 4, there are multiple positioning grooves 40. There is a one-to-one correspondence between the positioning grooves 40 and the positioning blocks 30. At both ends of the pressing block 4, there are convex platforms 33. At both ends of the clamping backing plate 3, there is a pair of downward extending convex plates 34. A rotating pressing plate 35 is rotatably arranged on the downward extending convex plates 34. On the inner wall of the upper end of the rotating pressing plate 35, there is a downward pressing rod 36. The outer periphery of the downward pressing rod 36 closely adheres to the upper wall of the downward extending convex plate 34. A compression spring is sleeved on the lower end of the vertical rod 32. The compression spring is located between the pressing block 4 and the clamping backing plate 3.

[0022] During the operation of this embodiment, the operator places the housing of the connector on the bottom plate 1. When placing, the open end of the housing faces the side of the positioning push plate 21, and the pins on the connector are inserted into the U-shaped groove 11.

[0023] When placing the housing, the operator rotates the V-shaped plate 25 so that the V-shaped plate 25 acts on the outer pull plate 20, thereby causing the outer pull plate 20 to move outward. And when the outer pull plate 20 moves outward, it will cause the positioning push plate 21 to move outward. And when moving outward, the spring 23 will be compressed.

[0024] After the housing is placed, the operator cancels the rotation of the V-shaped plate 25. Then the positioning push plate 21 moves inward under the action of the spring 23 and finally completes the positioning operation of the housing through the positioning push plate 21 and the end plate 10.

[0025] Then the operator places the wire part of each connecting wire on the pins. After placing, the pressing block is sleeved on the vertical rod 32. After placing, the rotating pressing plate 35 is rotated. And when the rotating pressing plate 35 rotates, the outer periphery of the downward pressing rod 36 will closely adhere to the upper wall of the downward extending convex plate 34, thereby positioning the connecting wire and the pins through the positioning grooves 40 on the pressing block 4.

[0026] Finally, the welding operation of the connecting wire is carried out.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
