[0002] Wire harness terminal crimping equipment is an important tool used to connect wires or cables to electrical equipment. Its main function is to provide reliable electrical connections and mechanical fixation. By applying pressure using specialized tools, the metal material of the terminal is pressed together to form a high-quality metal-to-metal contact with the wire or cable, thereby enabling current transmission and preventing the connection from loosening or breaking.

[0003] Currently, when crimping the terminals of wire harness components used in home appliances, workers usually need to manually support and adjust them. Because the position is easily deviated and unstable when manually supporting and limiting the position, it will cause offset and misalignment during subsequent crimping, which will easily affect the quality of processing. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a terminal crimping device for a household appliance wiring harness assembly with a positioning structure, such as... Figure 1-4 As shown, it includes a base 1 and a pressing device 2: a motor 5 is fixedly connected to the front of the base 1, a lead screw 6 is fixedly connected to the output shaft of the motor 5 through a coupling, a threaded movable block 7 is movably connected to the outer wall of the lead screw 6, a movable plate 8 is fixedly connected to the top of the threaded movable block 7, a guide block 9 is fixedly connected to the bottom of the movable plate 8, a movable seat 10 is fixedly connected to the top of the movable plate 8, an adjusting rod 11 is movably connected to the inner wall of the movable seat 10, and a rotating ring 12 is fixedly connected to the outer wall of the adjusting rod 11.

[0023] An adjusting tube 13 is movably connected to the outer wall of the adjusting rod 11. A placement plate 14 is fixedly connected to one end of the adjusting tube 13. A placement groove 15 is provided on the top of the placement plate 14. A docking block 16 is fixedly connected to one side of the placement plate 14. A sleeve 17 is fixedly connected to the inner wall of the docking block 16. An iron sheet 18 is fixedly connected to the top of the placement plate 14. A shaft bracket 19 is fixedly connected to one side of the placement plate 14. A limiting plate 20 is movably connected to the outer wall of the shaft bracket 19. A docking post 21 is fixedly connected to one side of the limiting plate 20. A magnet 22 is fixedly connected to the bottom of the limiting plate 20.

[0024] It should be noted that, since existing wire harness assembly terminals for home appliances typically require manual adjustment and support during crimping, manual support can easily cause instability and displacement, leading to misalignment and affecting processing quality. Therefore, to address this issue, this solution uses a placement plate 14 and a limiting plate 20. The wire harness terminals to be crimped are placed sequentially on the placement plate 14. Rotating the limiting plate 20, in conjunction with the shaft bracket 19, allows it to cover the placement plate 14, and the mating post 21 inserts into the mating block 16, connecting the limiting plate 20 and the placement plate 14. This secures the wire harness terminals. The motor 5 drives the lead screw 6 to rotate, adjusting the placement plate 14 to move closer to the crimping device 2, ensuring stable crimping of the wire harness terminals.

[0025] Specifically, in this embodiment, the solution mainly includes a movable groove 3 and a guide groove 4 respectively opened on the top of the base 1, and the inner wall of the movable groove 3 and the inner wall of the guide groove 4 are movably connected to the outer wall of the threaded movable block 7 and the outer wall of the guide block 9 respectively.

[0026] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the inner wall of the movable seat 10 is provided with a bearing, and the inner ring of the bearing is fixedly connected to one end of the adjusting rod 11. The movable seat 10 is movably connected to the adjusting rod 11 through the bearing, so that the adjusting rod 11 and the movable plate 8 can be movably installed, thereby adjusting the support height of the placement plate 14 according to the usage requirements.

[0027] In this embodiment, according to the number of crimping operations, appropriate wire harness terminals are first placed sequentially in the placement slots 15 on the placement base 14. Then, the rotating limiting plate 20 is rotated with the cooperation of the shaft frame 19 so that it can cover the placement plate 14, so that the iron sheet 18 and the magnet 22 are magnetically attracted. At the same time, the docking post 21 is inserted into the docking block 16. The docking block 16 is provided with a retainer 17, which can improve the tightness between the docking block 16 and the docking post 21, so that the limiting plate 20 can press against the wire harness terminals. Then, the starting motor 5 drives the lead screw 6 to rotate, so that the threaded movable block 7 outside the lead screw 6 moves, and simultaneously drives the moving plate 8 and the placement base 14 as a whole to move closer to the crimping device 2, so that it can move stably to the crimping position for processing operations, avoiding the inconvenience and misalignment caused by the manual limiting method.

[0028] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the outer wall of the adjusting rod 11 and the inner wall of the adjusting tube 13 are both provided with threads, and the adjusting rod 11 is threadedly connected to the adjusting tube 13.

[0029] In this embodiment, the adjusting rod 11 can be rotated according to the height of the pressing mold to adjust the support height of the placement plate 14, thereby improving applicability and avoiding usage limitations.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the top of the docking block 16 has an installation groove that matches the sleeve 17. The diameter of the sleeve 17 matches the diameter of the docking post 21, and the sleeve 17 is a rubber sleeve.

[0031] In this embodiment, the sleeve 17 can be fixed to the docking block 16, and the docking post 21 can be tightly inserted into the docking block 16, so that the limiting plate 20 and the placement plate 14 can be firmly connected.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, the limiting plate 20 is movably connected to the placement plate 14 via the shaft bracket 19, and the bottom of the limiting plate 20 is provided with a groove that matches the placement slot 15.

[0033] In this embodiment, the adjustable limit plate 20 is easy to rotate, which improves the convenience of the limiting operation and can effectively limit the wire harness.

[0034] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a bearing is provided at one end of the lead screw 6, and the lead screw 6 is movably connected to the movable groove 3 through the bearing.

[0035] In this embodiment, the lead screw 6 can be movably installed with the movable groove 3, thereby enabling the lead screw 6 to rotate stably and normally.
