Description

Technical Field

[0001] The utility model relates to the technical field of wire crimping equipment, in particular to a manual wire crimping machine. Background Art

[0002] Wire crimping terminals are usually installed at the end of the automotive wiring harness. Depending on the current, the diameter of the control wire varies greatly. For some special vehicles, such as the main control wire in new energy vehicles, the diameter is significantly larger than other control wires. Therefore, it is difficult for existing automatic wire crimpers to achieve a good crimping and fixing effect.

[0003] In the prior art, there is a patent application document with the announcement number CN209896415U and the patent name of a multi-interface manual wire crimping machine. In this document, by setting up three parts, namely the basic component, the pressing component and the interface component, different interface structures can be replaced as needed during use to achieve the pressing and fixing of different types of wires. However, due to the large degree of deformation of the wire port after being compressed, it is very easy to fill the entire interface component. After the wire harness and the terminal are fixed, it often fills the entire cavity and is difficult to demold. If it is forcibly dragged, the force is uneven, which can easily cause deformation at the wire interface and affect the connection effect. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a manual wire crimping machine, which can not only adjust the pressure of the wire crimping plate according to the diameter of the wire to facilitate the fixation of the wire crimping terminal, but also can quickly separate the wire from the mold cavity after the wire crimping is completed to ensure the connection stability of the wire crimping terminal.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a manual wire crimping machine, characterized in that it includes a fixing part, a wire crimping part and a lifting part; the fixing part includes a lower support plate and an upper support plate, the lower support plate is provided with a groove, and a terminal fixing seat is fixedly arranged in the groove; a support column is fixedly arranged between the upper support plate and the lower support plate; the wire crimping part is located between the lower support plate and the upper support plate, the wire crimping part includes a wire crimping block, a wire crimping plate and a connecting block, the wire crimping block is provided with a limiting hole adapted to the wire crimping plate and the connecting block, and the wire crimping plate slides in the limiting hole; the lifting part includes a handle, a pressing rod, and a support rod, a guide rod is provided between the wire crimping block and the upper support plate, the wire crimping block is fixedly arranged at the bottom of the guide rod, a sliding block is slid on the guide rod, and the sliding block is fixedly connected to the connecting block; the end of the handle is hinged to the support rod, the upper end of the pressing rod is hinged to the handle, and the lower end penetrates the upper support plate and is hinged to the sliding block.

[0006] Preferably, the wire pressing plate comprises a first wire pressing plate and a second wire pressing plate, and a wire pressing groove is respectively provided in the middle of the first wire pressing plate and the second wire pressing plate.

[0007] Preferably, a guide plate is provided on the connecting block, and the first wire pressing plate and the second wire pressing plate are both slidably connected to the guide plate.

[0008] Preferably, a limiting boss is fixedly provided on the connecting block, and the limiting boss is located at the far end of the wire pressing plate.

[0009] Preferably, the wire pressing plate is close to the supporting column.

[0010] Preferably, a discharge plate is fixedly provided at one end of the wire pressing block, and a guide side wall is also provided inside the wire pressing block.

[0011] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0012] 1. Since a wire pressing part is arranged between the lower support plate and the upper support plate, and the lifting part is used to drive the wire pressing part to move up and down, the terminal is pressed and held, and the lifting part includes a handle, a pressing rod, and a supporting rod. After the handle is hinged to the supporting rod, it serves as a fulcrum, and the lifting part serves as a simple lever to drive the wire pressing block to move up and down to fix the wire pressing terminal. The force applied can be adjusted at any time according to the actual diameter of the wire and the degree of deformation of the wire pressing terminal. It is particularly suitable for fixing the terminal on irregular wires.

[0013] 2. Since the crimping block, crimping plate and connecting block are provided, the connecting block is fixedly connected to the slider, and the slider can only move in the vertical direction through the guide rod, so it can be ensured that the force direction is always perpendicular to the crimping terminal. At the same time, an opening is provided on the crimping block to ensure the movement direction of the crimping plate; when the crimping is completed, when the crimping plate moves upward, since the crimping block is stationary relative to the limit plate, the crimping terminal can be quickly disengaged to ensure the stability of the connection.

[0014] 3. Due to the addition of a stripper plate and the provision of a guide side wall on the inner wall of the crimping block, the two guide plates can be forced to move downward and inward, which will have a better squeezing effect on the crimping terminal and cause it to deform more, thereby further ensuring the stability of the crimping terminal connection.

[0021] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] See also Figure 1-Figure 3The utility model provides a manual wire crimping machine, including a fixing part 1, a wire crimping part 2 and a lifting part 3; the fixing part 1 includes a lower support plate 11 and an upper support plate 12, the lower support plate 11 is provided with a groove, and a terminal fixing seat 13 is fixed in the groove; the terminal fixing seat 13 is used to place the wire crimping terminal to be fixed. According to the actual diameter of the wire and the size of the wire crimping terminal, a suitable terminal fixing seat 13 is selected. A support column 14 is fixedly arranged between the upper support plate 12 and the lower support plate 11; the wire pressing part 2 is located between the lower support plate 11 and the upper support plate 12, and the wire pressing part 2 includes a wire pressing block 21, a wire pressing plate 22 and a connecting block 23. The wire pressing block 21 is provided with a limiting hole adapted to the wire pressing plate 22 and the connecting block 23, and the wire pressing plate 22 slides in the limiting hole; the lifting part 3 includes a handle 31, a pressing rod 32, and a support rod 33. A guide rod 24 is arranged between the wire pressing block 21 and the upper support plate 12, and the wire pressing block 21 is fixedly arranged at the bottom of the guide rod 24. A slider 25 slides on the guide rod 24, and the slider 25 is fixedly connected to the connecting block 23; the end of the handle 31 is hinged to the support rod 33, the upper end of the pressing rod 32 is hinged to the handle 31, and the lower end penetrates the upper support plate 12 and is hinged to the slider 25. When in use, first hinge the end of the handle 31 with the support rod 33, and the junction of the pressure rod 32 should be close to the top of the support rod 33, so that pressing down will be more labor-saving. The wire and the wire terminal are placed in the terminal fixing seat 13. When the handle 31 drives the pressure rod 32 to press downward, the slider 25 slides downward along the guide rod 24, and then drives the connecting block 23 and the wire pressing plate 22 to move downward, so that the wire terminal and the wire are deformed together, and the distance of the lower limit of movement is generally controlled by the height of the limiting boss 26. In order to be applicable to various types of wires, the height of the limiting boss 26 can be adjusted, and it can be fixed by limiting nuts in different positions. After the wiring terminal of the wire is fixed, the handle 31 drives the pressure rod 32 to move upward. Under normal circumstances, the wire and the wire terminal will automatically fall under gravity at this time. If they are stuck in the cavity of the limiting block, when the wire pressing plate 22 continues to move upward, it will pass through the limiting hole with a smaller width, forcing the wire terminal and the wire to be separated together. In this process, the volume of the limiting hole is small, and the crimping terminal and the wire are subjected to force together, which can effectively prevent the position of the crimping terminal from changing due to large deformation.

[0023] The wire pressing plate 22 of the utility model includes a first wire pressing plate and a second wire pressing plate, and the first wire pressing plate and the second wire pressing plate are respectively provided with a wire pressing groove in the middle. The ends of the first wire pressing plate and the second wire pressing plate are flat, and the pressure is greater when combined with the wire pressing groove in the middle, so that the wire pressing terminal can be better extruded and formed.

[0024] In the utility model, a limiting slide is provided on the connection block, and the first crimping plate and the second crimping plate are both slidably connected to the limiting slide. The limiting slide is mainly used to fix the first crimping plate and the second crimping plate, and cooperates with the guide side wall 212 in the crimping block 21. When the two crimping plates 22 move downward, they will also gather toward the middle, so that the contact area between the crimping terminal and the wire material is larger.

[0025] The connection block 23 of the utility model is fixed with a limiting boss 26, which is located at the far end of the wire pressing plate 22. The limiting boss 26 is generally used to limit the downward distance of the connection block 23, and is suitable for batches of wires of the same specification. The limiting boss 26 is generally fixed by a nut, and its height can be adjusted according to the diameter of the wire.

[0026] The wire pressing plate 22 of the present invention is close to the support column 14. The upper end of the wire pressing plate 22 is close to the support column 14, which can better play the advantage of leverage, and pressing down will save more effort.

[0027] One end of the wire pressing block 21 of the utility model is fixed with a stripper plate 211. The main function of the stripper plate 211 is to block the wire and the wire pressing terminal so that they can be quickly separated. For some types of wire pressing terminals, they will be completely stuck in the cavity of the wire pressing block 21 after deformation. At this time, the stripper plate 211 can be directly removed for maintenance operations.

[0028] Of course, the present invention may have other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding modifications according to the present invention.

[0029] However, these corresponding changes and deformations should all fall within the protection scope of the claims attached to the utility model.
