It aims to solve the problem that the existing high-voltage wire shielding ring crimping of new energy vehicles generally adopts a six-sided crimping method, and each step often requires tooling or molds. However, at present, there is a lack of effective tools to meet the crimping requirements of high-voltage wire harnesses. Even with ordinary simple crimping molds, the crimping purpose can only be achieved, but the problem of high-voltage wire harness shielding ring misalignment during crimping cannot be solved. Furthermore, there is no good scale reference during the crimping process, which reduces the convenience.

Finally, the adjusted position of the sliding seat can be fixed by the limiting structure, thus ensuring that the shielding ring will not shift during crimping and that the high-voltage wire harness shielding ring is crimped into the required installation position of the high-voltage wire harness, improving convenience.
[0014] Pulling the lever moves the movable block, causing the connecting block to retract, which in turn causes the limiting protrusion to disengage from the limiting groove. At this point, the sliding seat can slide along the slide groove under the action of the slider. When the sliding seat moves to the appropriate position, releasing the lever allows the movable block to eject the connecting block under the action of the spring, causing the limiting protrusion to embed into the corresponding limiting groove, thereby improving the ease of adjusting the sliding seat.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 This utility model provides the following technical solution: a positioning fixture for crimping a high-voltage wire shielding ring for a new energy vehicle, comprising a base 1, a connecting seat 2 connected to the outer wall of the base 1, a sliding seat 3 provided on the outer wall of the connecting seat 2, a groove 4 provided on the top of the base 1, a stud base 5 provided on the inner side of the groove 4, a screw hole fixing platform 6 provided on the top of the stud base 5, sliding grooves 7 provided on both outer walls of the connecting seat 2, a slider 8 connected to the inner wall of the sliding seat 3, a wire clamping groove 9 provided on the top of the sliding seat 3, and a scale 10 provided on the top of the connecting seat 2.
[0023] Preferably, the cross-sections of the groove 4 and the stud base 5 are both trapezoidal, and the sliding seat 3 can form a sliding connection structure with the connecting seat 2 through the sliding groove 7 and the slider 8.
[0024] In practical use, the high-voltage wire to be crimped with the shielding ring is placed in the wire slot 9, and the wire slot 9 is used to ensure that the high-voltage wire harness does not shift. Then, the screw hole fixing platform 6 on the stud base 5 is used to fix it to the inner hole of the wire lug at the end of the high-voltage wire. At the same time, the position of the high-voltage wire harness crimping with the shielding ring is adjusted by the sliding connection structure between the sliding seat 3 and the connecting seat 2 and by referring to the scale 10 on the connecting seat 2. Finally, the position of the sliding seat 3 after adjustment is fixed by the limiting structure, so as to ensure that the shielding ring does not shift during crimping and that the high-voltage wire harness shielding ring is crimped in the required installation position of the high-voltage wire harness.
[0025] It should be noted that the limiting structure consists of a mounting groove 12, a mounting base 13, a pull rod 14, a movable block 15, a connecting block 16, a spring 17, a limiting protrusion 18, a fixing plate 19, a fixing bolt 20, and a threaded hole 21.
[0026] Preferably: the top of the connecting seat 2 is provided with multiple limiting grooves 11, one end of the sliding seat 3 is provided with a mounting groove 12, the inner side of the mounting groove 12 is provided with a mounting seat 13, the top of the mounting seat 13 is provided with a pull rod 14, one end of the pull rod 14 is connected to a movable block 15, the bottom of the movable block 15 is connected to a connecting block 16, the outer wall of the pull rod 14 is sleeved with a spring 17, the bottom of the connecting block 16 is connected with multiple limiting protrusions 18, the multiple limiting grooves 11 are evenly distributed, and the dimensions of the limiting protrusions 18 and the limiting grooves 11 are matched, the end of the pull rod 14 away from the movable block 15 is annular, and the spring 17 is located inside the mounting seat 13;
[0027] It should be noted that the spacing between the multiple limiting grooves 11 is adapted to the spacing between the multiple limiting protrusions 18. The limiting protrusions 18 can form an elastic structure with the mounting base 13 through the pull rod 14, the movable block 15, the connecting block 16, and the spring 17.
[0028] In practical use, the movable block 15 is pulled by the lever 14 to retract the connecting block 16, causing the limiting protrusion 18 to disengage from the limiting groove 11. At this time, the sliding seat 3 can slide along the slide groove 7 under the action of the slider 8. When the sliding seat 3 moves to the appropriate position, the lever 14 is released, allowing the movable block 15 to drive the connecting block 16 to pop out under the action of the spring 17, so that the limiting protrusion 18 is embedded in the corresponding limiting groove 11, thereby improving the ease of adjustment of the sliding seat 3.
[0029] Preferably, the two outer walls of the mounting base 13 are connected to fixing plates 19, the top of the fixing plates 19 is provided with fixing bolts 20, and the top of the sliding base 3 is provided with threaded holes 21.
[0030] In practical use, by connecting the fixing bolt 20 through the fixing plate 19 and the threaded hole 21 on the sliding seat 3, the mounting seat 13 can be fixedly installed in the mounting groove 12.
[0031] Conversely, the mounting base 13 can be removed from the sliding base 3 by removing the fixing bolt 20.
[0032] Working principle: First, the high-voltage wire to be crimped with the shielding ring is placed in the wire slot 9. Then, the wire slot 9 ensures that the high-voltage wire harness does not shift. Next, the screw hole fixing platform 6 on the stud base 5 is used to fix it to the inner hole of the wire lug at the end of the high-voltage wire. At the same time, the crimping position of the high-voltage wire harness with the shielding ring is adjusted by the sliding connection structure between the sliding seat 3 and the connecting seat 2, and with reference to the scale 10 on the connecting seat 2. Finally, the adjusting position of the sliding seat 3 is fixed by the limiting structure, thus ensuring that the shielding ring does not shift during crimping. Furthermore, it can press the high-voltage harness shielding ring onto the required installation position of the high-voltage harness, and pull the movable block 15 through the pull rod 14 to drive the connecting block 16 to retract, so that the limiting protrusion 18 will disengage from the limiting groove 11. At this time, the sliding seat 3 can slide along the slide groove 7 under the action of the slider 8. When the sliding seat 3 moves to the appropriate position, by releasing the pull rod 14, the movable block 15 can drive the connecting block 16 to pop out under the action of the spring 17, so that the limiting protrusion 18 is embedded in the corresponding limiting groove 11, thereby improving the convenience of adjusting the sliding seat 3.
[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
