[0001] This invention relates to the field of pressing device technology, specifically a connector pressing device. Background Technology

[0002] Automotive connectors are components used in the intelligent cockpit domain control of new energy vehicles. They bridge gaps in circuits or connect isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Automotive connectors come in a wide variety of forms and structures, but they are mainly composed of four basic structural components, commonly referred to in the industry as sheaths, connectors, and plastic shells. During operation, due to the complexity of road conditions and prolonged exposure to bumps and vibrations, the wiring harness connections of automotive connectors are prone to loosening and detachment. This can affect the use of internal electrical components and potentially impact the normal operation of the vehicle's ABS and EPS systems.

Furthermore, traditional crimping devices have complex structures, high manufacturing costs, and are not conducive to later maintenance. Therefore, a new technical solution is needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a connector crimping device to solve the problems of current connector crimping devices, which require selecting appropriate crimping components based on the diameter of the wire harness and connector when crimping wire harnesses and connectors, and needing to replace appropriate crimping components when crimping connectors and wire harnesses of different sizes, thereby reducing the convenience of the crimping device in use. In addition, traditional crimping devices have complex structures, high manufacturing costs, and are not conducive to later maintenance.

The other end of the I-beam plate is equipped with a stroke component, which is used to change the pressing range of the elastic pressing component; The travel assembly includes a conical spiral wheel, which works in conjunction with an elastic pressing assembly to press connector harnesses of different sizes.

[0006] In a preferred embodiment of the present invention, the elastic pressing component is an elastic deformation ring, the elastic deformation ring has a stroke groove, and one end of the stroke groove is integrally formed with an elastic arc plate.

[0007] In a preferred embodiment of the present invention, the driving assembly includes a gear, one end of which is fixedly connected to one end of a conical spiral wheel, and one end of the conical spiral wheel is rotatably connected to the inside of one end of the I-shaped plate.

[0008] In a preferred embodiment of the present invention, the toothed end of the gear is engaged with a toothed plate, one end of the toothed plate is fixedly connected to a guide rod, and a return spring is sleeved on the outside of the guide rod.

[0009] In a preferred embodiment of the present invention, the other end of the guide rod movably passes through the interior of one end of the support plate, the other end of the support plate is fixedly connected to the top of the mounting bracket, one end of the return spring abuts against one end of the bottom of the toothed plate, and the other end of the return spring abuts against one side of the support plate.

[0010] In a preferred embodiment of the present invention, multiple gears are provided, one end of which is fixedly connected to the output end of the drive motor, the other ends of the other gears are fixedly connected to one end of the drive shaft, and the other end of the drive shaft is fixedly connected to the other end of the conical spiral wheel.

[0011] In a preferred embodiment of the present invention, the travel assembly includes a T-shaped plate, a longitudinal travel plate is movably connected to one end of the T-shaped plate, a guide wheel is rotatably connected to one end of the longitudinal travel plate, the other end of the longitudinal travel plate is fixedly connected to one end of a connecting plate, and the other end of the connecting plate is fixedly connected to the other end of an elastic arc plate.

[0012] In a preferred embodiment of the present invention, the other end of the T-shaped plate is slidably connected to the inside of the through groove, and the through groove penetrates the inside of the other end of the I-shaped plate.

[0013] In a preferred embodiment of the present invention, an extension groove is provided on one side of the mounting bracket, the size of which matches the size of the through groove and their positions are corresponding.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When the wire harness and connector are crimped together, the present invention first drives a gear to rotate counterclockwise by a drive motor. This gear drives a conical spiral wheel to rotate counterclockwise. The conical spiral wheel then drives other gears to rotate via a drive shaft, and these other gears drive other conical spiral wheels to rotate, thus achieving synchronous operation. This allows one motor to drive multiple conical spiral wheels. During the rotation of the conical spiral wheels, the guide wheel moves from the smallest segment to the largest segment. During this process, the guide wheel drives the longitudinal travel plate to move downwards inside the T-shaped plate. Simultaneously, the longitudinal travel plate drives the T-shaped plate to move towards the mounting bracket position inside the through slot. This allows the connecting plate to compress the elastic arc plate, thereby crimping the wire harness and connector placed within the elastic deformation ring. This allows the crimping assembly to automatically adjust according to the diameter of the wire harness and connector, increasing the crimping range of the device and improving its convenience in crimping wire harnesses and connectors. When the rotational torque of the drive motor reaches the maximum rebound force of the return spring, the drive motor will stop rotating. At the same time, the return spring will generate a rebound force on the toothed plate, causing the toothed plate to drive the gear to rotate, thereby resetting the toothed plate. During this process, the gear will drive the conical spiral wheel to reset, the conical spiral wheel will drive the guide wheel to reset, and the guide wheel will drive the T-shaped plate to reset through the longitudinal stroke plate, thus achieving automatic reset of the elastic pressing component. This allows the drive motor to rotate in one direction, saving energy consumption during the use of the pressing device, extending the service life of the drive motor, and further improving the convenience of using the pressing device. When the drive motor drives a gear to rotate, the gear drives a conical spiral wheel to rotate. The conical spiral wheel then drives other gears to rotate via the drive shaft, and these other gears drive other conical spiral wheels to rotate, thus achieving synchronous operation. This allows one motor to drive multiple conical spiral wheels, saving manufacturing costs for the pressing device, reducing the difficulty and cost of later maintenance, and further improving the convenience of using the pressing device.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] Example 1: A connector pressing device, see [link to example]. Figures 1 to 6 It includes a mounting bracket 1, on the base plate of the mounting bracket 1, an elastic pressing component is fixedly mounted for pressing connector wire harnesses of different sizes; The top of the mounting bracket 1 is fixedly connected to an I-beam plate 11, and a drive assembly is installed at one end of the I-beam plate 11 for adjusting the position of the stroke assembly. The other end of the I-beam plate 11 is equipped with a stroke component, which is used to change the pressing range of the elastic pressing component; The travel assembly includes a conical spiral wheel 16, which, in conjunction with an elastic pressing assembly, presses together connector harnesses of different sizes. When the harness and connector are pressed together, the drive motor 2 first drives a gear 15 to rotate counterclockwise. This gear 15 then drives a conical spiral wheel 16 to rotate counterclockwise. The conical spiral wheel 16 then drives other gears 15 to rotate via the drive shaft 21, and so on, achieving synchronous operation. Thus, one motor drives multiple conical spiral wheels 16. During the rotation of the conical spiral wheel 16, the guide wheel 24 moves along the conical spiral wheel 16... The smallest segment of segment 6 moves towards the largest segment. During this process, the guide wheel 24 drives the longitudinal travel plate 23 to move downward inside the T-shaped plate 22. At the same time, the longitudinal travel plate 23 drives the T-shaped plate 22 to move towards the position of the mounting bracket 1 inside the through groove 26. This allows the connecting plate 25 to compress the elastic arc plate 14, thereby pressing the wire harness and connector placed in the elastic deformation ring 12. This allows the pressing assembly to automatically adjust according to the diameter of the wire harness and connector, increasing the range of the pressing device when pressing the wire harness and connector, and improving the convenience of the pressing device when pressing the connector and wire harness.

[0020] For details, see Figure 6 The elastic pressing component uses an elastic deformation ring 12, on which a stroke groove 13 is provided. One end of the stroke groove 13 is integrally formed with an elastic arc plate 14, which allows the elastic pressing component to automatically reset without being squeezed by external force, thereby improving the convenience of the pressing device during use.

[0021] Further, see Figures 1 to 4The drive assembly includes a gear 15, one end of which is fixedly connected to one end of a conical spiral wheel 16. One end of the conical spiral wheel 16 is rotatably connected to the interior of one end of an I-beam plate 11. The toothed end of the gear 15 meshes with a toothed plate 17. One end of the toothed plate 17 is fixedly connected to a guide rod 18. A return spring 19 is sleeved on the outside of the guide rod 18. The other end of the guide rod 18 movably passes through the interior of one end of a support plate 29. The other end of the support plate 29 is fixedly connected to the top of the mounting bracket 1. One end of the return spring 19 abuts against one end of the bottom of the toothed plate 17, and the other end abuts against one side of the support plate 29. When the rotational torque of the drive motor 2 reaches the return spring 19... When the maximum rebound force of spring 9 is reached, the drive motor 2 will stop rotating. At the same time, the return spring 19 will generate a rebound force on the toothed plate, causing the toothed plate to drive the gear 15 to rotate, thereby resetting the toothed plate. During this process, the gear 15 will drive the conical spiral wheel 16 to reset, and the conical spiral wheel 16 will drive the guide wheel 24 to reset. At the same time, the guide wheel 24 will drive the T-shaped plate 22 to reset through the longitudinal stroke plate 23, thereby achieving automatic reset of the elastic pressing component. This allows the drive motor 2 to rotate in one direction, saving energy consumption during the use of the pressing device, extending the service life of the drive motor 2, and improving the convenience of the pressing device during use.

[0022] Further, see Figure 1 and Figure 3 Multiple gears 15 are provided. One end of one gear 15 is fixedly connected to the output end of the drive motor 2, and the other ends of the other gears 15 are fixedly connected to one end of the drive shaft 21. The other end of the drive shaft 21 is fixedly connected to the other end of the conical spiral wheel 16. When the drive motor 2 drives one gear 15 to rotate, one gear 15 will drive one conical spiral wheel 16 to rotate. Then, the conical spiral wheel 16 drives other gears 15 to rotate through the drive shaft 21. Then, the other gears 15 drive other conical spiral wheels 16 to rotate, thereby achieving synchronous operation. As a result, one motor drives multiple conical spiral wheels 16 to operate, saving the manufacturing cost of the pressing device and reducing the difficulty and cost of later maintenance of the pressing device.

[0023] It is worth noting that, see Figure 4 and Figure 5The travel assembly includes a T-shaped plate 22, with a longitudinal travel plate 23 movably connected to one end of the T-shaped plate 22. A guide wheel 24 is rotatably connected to one end of the longitudinal travel plate 23, and the other end of the longitudinal travel plate 23 is fixedly connected to one end of a connecting plate 25. The other end of the connecting plate 25 is fixedly connected to the other end of an elastic arc plate 14. The other end of the T-shaped plate 22 is slidably connected to the inside of a through groove 26, which penetrates the inside of the other end of an I-shaped plate 11. When the guide wheel 24 moves on the conical spiral wheel 16, the guide wheel 24 drives the longitudinal travel plate 23 to move up and down inside the T-shaped plate 22. At the same time, the longitudinal travel plate 23 drives the T-shaped plate 22 to move laterally inside the through groove 26, thereby allowing the connecting plate 25 to compress or reset the elastic arc plate 14, thus achieving the pressing process of the wire harness and connector placed in the elastic deformation ring 12.

[0024] It is worth noting that, see Figure 2 An extension slot 27 is provided on one side of the mounting bracket 1. The size of the extension slot 27 matches the size of the through slot 26 and their positions are corresponding. In order to allow the T-shaped plate 22 to pass through the extension slot 27 of the mounting bracket 1, the T-shaped plate 22 can be adjusted in position, thereby changing the lateral position of the longitudinal travel plate 23.

[0025] It is worth mentioning that, see Figure 4 The support plate 29 has a through groove 28. The size of the through groove 28 is the same as the cross-section of the toothed plate 17 and corresponds to the position of the toothed plate 17. In order to facilitate the toothed plate 17 to pass through the through groove 28 of the support plate 29, the position of the toothed plate 17 can be adjusted.
