[0020] Embodiment 1:

[0021] As shown in the drawings, Figures 1-4 The present application provides a technical solution: a wire harness terminal crimping device, comprising a supporting plate 1, one side of the supporting plate 1 being rotatably connected with a rotating plate 2, one side of the supporting plate 1 being provided with a supporting hole 3, the inner wall of the supporting hole 3 being provided with two limiting grooves 4, one side of the supporting plate 1 being provided with a rotating hole 5, the outer surface of the rotating plate 2 being fixedly connected with a half gear 6, the outer surface of the half gear 6 being slidably connected with the inner wall of the rotating hole 5, the inner wall of the supporting hole 3 being slidably connected with a row of teeth 10, one side of the row of teeth 10 being fixedly connected with a pressing plate 17, and corresponding crimping grooves 9 being provided between one side of the supporting plate 1 and one side of the pressing plate 17;

[0022] The outer surface of the row of teeth 10 is fixedly connected with two baffles, and the outer surface of the baffle is slidably connected with the inner wall of the limiting groove 4;

[0023] Through the above-mentioned embodiments, the rotating plate 2 is rotated through the handle 16, and then the row of teeth 10 is moved through the half gear 6, and the structure of the row of teeth 10 is more stable through the cooperation of the two baffles and the limiting groove 4, and then when the two handles 16 are close, the pressing plate 17 is moved towards the supporting plate 1 through the row of teeth 10, and if the crimping groove 9 on the supporting plate 1 is provided with a terminal inside, the terminal inside the crimping groove 9 on the supporting plate 1 is crimped through the pressing plate 17 at this time;

[0024] A sliding hole 7 is provided on one side of the support plate 1. A limiting plate 11 is slidably connected to the inner wall of the sliding hole 7. One side of the limiting plate 11 is fixedly connected to one side of the pressure plate 17.

[0025] A limiting hole 8 is provided on one side of the support plate 1. A limiting rod 12 is slidably connected to the inner wall of the limiting hole 8. One end of the limiting rod 12 is fixedly connected to one side of the limiting plate 11.

[0026] Handles 16 are fixedly connected to one side of both the support plate 1 and the rotating plate 2;

[0027] Through the above embodiments, the handle 16 can be used to control the support plate 1 and the rotating plate 2. The sliding hole 7 and the limiting plate 11 can limit the pressure plate 17, making the movement trajectory of the pressure plate 17 more stable. At the same time, the limiting hole 8 and the limiting rod 12 can further limit the pressure plate 17, thereby making the movement trajectory of the pressure plate 17 more stable.

[0028] A rotating groove 13 is provided on one side of the rotating plate 2. A rotating rod 14 is rotatably connected to the inner wall of the rotating groove 13. One end of the rotating rod 14 is fixedly connected to one side of the support plate 1. A torsion spring 15 is provided on the outer surface of the rotating rod 14.

[0029] One end of the torsion spring 15 is fixedly connected to the inner wall of the rotating groove 13, and the other end of the torsion spring 15 is fixedly connected to one side of the support plate 1.

[0030] Through the above embodiments, the elastic potential energy provided by the torsion spring 15 enables the two handles 16 to automatically separate, thereby facilitating the separation of the two handles 16 and driving the pressure plate 17 away from the support plate 1, so as to remove the terminal between the pressure plate 17 and the support plate 1.

[0031] Working principle:

[0032] like Figures 1-4 As shown, during use, pressing the two handles 16 makes them contact each other, which drives the rotating plate 2 to rotate. The rotation of the rotating plate 2 increases the elastic potential energy of the torsion spring 15. The rotation of the rotating plate 2 drives the toothed rack 10 to move downward through the half gear 6. The movement of the toothed rack 10 drives the pressure plate 17 to move. The handles 16 make it easy to control the support plate 1 and the rotating plate 2. The sliding hole 7 and the limiting plate 11 can limit the pressure plate 17, making the movement trajectory of the pressure plate 17 more stable. At the same time, the limiting hole 8 and the limiting rod 12 can further limit the pressure plate 17, making the movement trajectory of the pressure plate 17 more stable. Thus, the pressure plate 17 can move steadily towards the support plate 1, and the terminal placed inside the crimping groove 9 on the support plate 1 will be crimped by the crimping groove 9 on the pressure plate 17.

[0033] After the crimping is completed, release the handle 16. Then the torsion spring 15 releases its elastic potential energy to drive the rotating plate 2 to rotate. The rotation of the rotating plate 2 drives the toothed rack 10 to move through the half gear 6, thereby moving the pressure plate 17 away from the support plate 1. At the same time, the two handles 16 separate, and the wire harness terminal can be taken out.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
