When the non-standard charging connector plug body a is fixed on the fixture base 1, the first fixing position a1 of the non-standard charging connector plug body a is placed in the first positioning groove 201 of the first positioning plate 2, the second fixing position a2 of the non-standard charging connector plug body a is placed in the second positioning groove 301 of the second positioning plate 3, and the pair of positioning blocks 4 abut against the third fixing position a3 of the non-standard charging connector plug body a, for initially positioning the non-standard charging connector plug body a on the fixture base 1.

[0033] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the top-pressing assembly 5 is installed at one end of the fixture base 1 near the first positioning plate 2, and is used to press against the top of the irregular charging connector plug body a. The top-pressing assembly 5 includes a pressure plate 501, which has an L-shaped structure. A receiving cavity is opened at the bottom end of the fixture base 1 near the first positioning plate 2. A channel 101 is opened at the top of the fixture base 1 along the length direction, which passes through the receiving cavity. The bent part of the pressure plate 501 is rotatably connected to the fixture base 1 through a rotating shaft 503. A first fixing post 504 is fixedly connected to one end of the pressure plate 501 inside the receiving cavity. A second fixing post 504 is fixedly connected inside the receiving cavity. The fixed post 505 and the first fixed post 504 are both fixedly connected to the second fixed post 505 with tension springs 506. When clamping and fixing the irregular charging connector plug body a, the tension springs 506 pull the pressure plate 501 at one end placed in the receiving cavity, so that the pressure plate 501 rotates around the rotating shaft 503, so that the other end of the pressure plate 501, that is, the end placed outside the fixture seat 1, presses against the fourth fixing position a4 of the irregular charging connector plug body a, thereby pressing and fixing the irregular charging connector plug body a, and improving the clamping and fixing effect of the irregular charging connector plug body a.

[0035] In this embodiment, as Figure 2 and Figure 5 As shown, the side pressure component 6 is installed at the other end of the side pressure component 6 and is used to press against the side of the irregular charging connector plug body a. The side pressure component 6 includes a slider 601. A groove 102 is opened at the top of the other end of the fixture seat 1. The slider 601 is slidably connected in the groove 102.

The end of the pull rod 603 away from the slider 601 slides through the fixture seat 1 and extends to the outside. A return spring 604 is sleeved between the slider 601 and the fixture seat 1 and outside the pull rod 603. When clamping and fixing the irregular charging connector plug body a, the return spring 604 pushes the slider 601 to move towards the irregular charging connector plug body a, so that the clamping block 602 abuts against the fifth fixed position a5 of the irregular charging connector plug body a, thereby improving the clamping and fixing effect of the irregular charging connector plug body a.

[0036] In this embodiment, as Figure 5 As shown, a second dovetail block is provided on one side of the clamping block 602, and a second dovetail groove is provided on the slider 601 for the second dovetail block to be inserted. The clamping block 602 and the slider 601 are fixedly connected by bolts. The clamping block 602 and the slider 601 are fixed by the insertion of the second dovetail block and the second dovetail groove, and then by bolts, which improves the assembly stability and facilitates the disassembly and replacement of the worn clamping block 602.

[0037] In this embodiment, as Figure 5 As shown, the linkage assembly 7 is used for the synchronous opening action of the top pressing assembly 5 and the side pressing assembly 6. The linkage assembly 7 includes a linkage sleeve 705 sleeved on the outside of the pressure plate 501. A linkage shaft 706 is fixedly connected to the pressure plate 501 at the linkage sleeve 705. Long slots 7051 are vertically opened on both sides of the linkage sleeve 705. The two ends of the linkage shaft 706 extend into the long slots 7051. A first linkage rod 707 is fixedly connected to the outside of the linkage sleeve 705. The pull rod 603 is placed in the treatment A second linkage rod 708 is fixedly connected to one end of the fixture base 1. The linkage assembly 7 also includes a slide rail 701 fixedly connected to one side of the fixture base 1. The slide rail 701 is arranged along the length direction of the fixture base 1. Two slide seats 702 are slidably connected to the slide rail 701. A connecting rod 703 is rotatably connected to the slide seat 702. The ends of the two connecting rods 703 away from the slide seats 702 are rotatably connected to a connecting seat 704. The first linkage rod 707 and the second linkage rod 708 are respectively fixedly connected to the two... Before the shaped charging connector plug body a is fixed to the fixture seat 1, the connecting seat 704 is pressed towards the fixture seat 1, causing the two connecting rods 703 to open and push the two slides 702 to slide on the slide rail 701, thereby increasing the distance between the two slides 702. The moving slides 702 drive the first linkage rod 707 and the second linkage rod 708 to move away from each other. The first linkage rod 707 drives the linkage sleeve 705 to move, causing the linkage shaft 706 to move in the long through groove 7051 of the linkage sleeve 705, thereby driving the pressure plate 501 to rotate upward and open. At the same time, the second linkage rod 708 drives the pull rod 603 to move outward from the fixture seat 1, pulling the slider 601 and the clamping block 602 to move away from the positioning block 4, so as to facilitate the synchronous opening action of the pressure plate 501 and the clamping block 602, which helps to position the shaped charging connector plug body a on the fixture seat 1 for clamping and fixing, improving the ease of operation.

[0038] Working principle: In use, by pressing the connecting seat 704 towards the fixture seat 1, the two connecting rods 703 open, pushing the two slides 702 to slide on the slide rail 701, increasing the distance between the two slides 702. The moving slides 702 drive the first linkage rod 707 and the second linkage rod 708 to move away from each other. The first linkage rod 707 drives the linkage sleeve 705 to move, causing the linkage shaft 706 to move within the elongated through groove 7051 of the linkage sleeve 705, causing the pressure plate 501 to rotate upward and open. At the same time, the second linkage rod 708 drives the pull rod 603 to move outward from the fixture seat 1, pulling the slider 601 and the clamping block 602 away from the positioning block 4, causing the pressure plate 501 and the clamping block 602 to open synchronously. Then, the irregular charging connector plug body a is placed on the fixture seat 1 for initial positioning. The first fixed position a1 of the irregular charging connector plug body a is placed in the first positioning groove 20 of the first positioning plate 2. Inside the fixture, the second fixing position a2 of the irregular charging connector plug body a is placed in the second positioning groove 301 of the second positioning plate 3. A pair of positioning blocks 4 are side-abutted against the third fixing position a3 of the irregular charging connector plug body a, so that the irregular charging connector plug body a is initially positioned on the fixture seat 1. Then, the pressed connecting seat 704 is released, and the pressure plate 501 is pulled into the receiving cavity by the action of the tension spring 506, so that the pressure plate 501 rotates around the rotating shaft 503, so that the pressure block 502 on the pressure plate 501 is pressed against the fourth fixing position a4 of the irregular charging connector plug body a. By the action of the return spring 604, the slider 601 is pushed to move towards the irregular charging connector plug body a, so that the clamping block 602 is pressed against the fifth fixing position a5 of the irregular charging connector plug body a, thereby improving the clamping and fixing effect of the irregular charging connector plug body a and avoiding problems such as shaking and displacement of the irregular charging connector plug body a during welding operations.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
