Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness terminal processing technology, specifically an automotive wiring harness terminal pressing mold. Background Technology

[0002] Automotive wiring harnesses are the core carrier of the entire vehicle's electrical system, undertaking key functions such as power transmission, signal control, and data communication. As the "neural network" of the vehicle, the wiring harness system organically connects hundreds of electronic components, including the battery, ECU control unit, sensors, lighting systems, and entertainment devices, through precisely arranged wires, connectors, terminals, and insulating sheaths, forming a complete onboard electrical network. With the development of intelligent driving and new energy technologies, the importance of high-voltage wiring harnesses and high-speed data wiring harnesses is becoming increasingly prominent, and wiring harness systems are continuously evolving towards lightweighting, integration, and high reliability.

[0003] Existing automotive wiring harness terminal crimping molds lack the ability to fix the wiring harness. When the equipment is running, the mechanical vibration can easily cause the wiring harness to shift, resulting in gaps or misalignments at the junction of the terminal and the wire. This not only reduces the product yield but also restricts the practicality of the automotive wiring harness terminal crimping mold. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes an automotive wiring harness terminal pressing mold.

[0005] The technical solution of this utility model is implemented as follows: an automotive wiring harness terminal pressing mold includes a base, a support frame and a first fixed seat are fixedly connected to the top of the base, a placement seat and a fixed mold are fixedly connected inside the first fixed seat, a hydraulic push rod is fixedly connected to one end of the support frame, a second fixed seat is fixedly connected to the bottom of the hydraulic push rod, a movable mold is fixedly connected inside the second fixed seat, a first groove is opened on the top of the placement seat, a second groove is opened on the top of the fixed mold, and a fixing component for fixing the wiring harness is provided on the first fixed seat.

[0006] Preferably, the fixing assembly includes a connecting shell fixed to a first fixing seat, a round rod slidably connected inside the connecting shell, a spring sleeved on the rod body, a fixing block fixedly connected to one end of the second fixing seat, a connecting block fixedly connected to the outside of the round rod, a first rack and a second rack slidably connected inside the connecting shell, a rotating rod rotatably connected inside the connecting shell, a first gear and a second gear fixedly connected to the outside of the rotating rod, a connecting seat fixedly connected to one side of the second rack, the connecting seat being hinged to a movable seat, a third slider fixedly connected to one side of the movable seat, a pressure plate rotatably connected inside the connecting shell, a fixing plate fixedly connected to one side of the pressure plate, and a groove formed on one side of the fixing plate.

[0007] Preferably, the top of the spring is fixedly connected to the fixing block, the bottom of the spring is fixedly connected to the connecting block, and the round rod passes through the fixing block.

[0008] Preferably, the bottom of the round rod is slidably connected to the first rack, the first rack is meshed with the first gear, and the second gear is meshed with the second rack.

[0009] Preferably, a first slider is fixedly connected to one side of the first rack, and a second slider is fixedly connected to the top of the second rack. Both the first and second sliders are "T" shaped, and the first and second sliders are slidably connected to the connecting shell.

[0010] Preferably, both the third slider and the groove on the fixed plate are "T" shaped, and the third slider is slidably connected to the groove on the fixed plate.

[0011] Preferably, a protrusion is provided on the other side of the pressure plate.

[0012] This utility model has the following beneficial effects:

[0013] This automotive wiring harness terminal crimping mold features a second fixed base and a movable mold extending downwards via a hydraulic pusher. A fixed block on the second fixed base is driven by a spring to move a round rod, which in turn moves a first rack. Subsequently, the kinetic energy transmission causes the second rack to push a connecting seat, which in turn pushes a movable seat. The movable seat then pushes a third slider to slide in a groove on the fixed plate, simultaneously causing the pressure plate to rotate until a protrusion on the pressure plate presses down on the wiring harness located in the first groove on the placement seat. By effectively fixing the wiring harness during the crimping process, mechanical vibration-induced wiring harness displacement is prevented, ensuring a tight fit between the terminal and the wire, avoiding gaps or misalignments. This not only improves the product yield but also enhances the practicality of the automotive wiring harness terminal crimping mold. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] like Figure 1-5 As shown, the automotive wiring harness terminal pressing mold provided in this embodiment includes a base 1. A support frame 2 and a first fixed seat 3 are fixedly connected to the top of the base 1. A placement seat 4 and a fixed mold 5 are fixedly connected inside the first fixed seat 3. A hydraulic push rod 6 is fixedly connected to one end of the support frame 2. A second fixed seat 7 is fixedly connected to the bottom of the hydraulic push rod 6. A movable mold 8 is fixedly connected inside the second fixed seat 7. A first groove 10 is opened on the top of the placement seat 4. A second groove 11 is opened on the top of the fixed mold 5. A fixing component 9 for fixing the wiring harness is provided on the first fixed seat 3.

[0023] Furthermore, the fixing component 9 includes a connecting shell 901 fixed on the first fixing seat 3, a round rod 902 slidably connected inside the connecting shell 901, a spring 903 sleeved on the rod body of the round rod 902, a fixing block 904 fixedly connected to one end of the second fixing seat 7, a connecting block 905 fixedly connected to the outside of the round rod 902, a first rack 906 and a second rack 911 slidably connected inside the connecting shell 901, a rotating rod 909 rotatably connected inside the connecting shell 901, a first gear 908 and a second gear 910 fixedly connected to the outside of the rotating rod 909, a connecting seat 913 fixedly connected to one side of the second rack 911, the connecting seat 913 is hinged to the moving seat 914, a third slider 915 fixedly connected to one side of the moving seat 914, a pressure plate 918 rotatably connected inside the connecting shell 901, a fixing plate 916 fixedly connected to one side of the pressure plate 918, and a groove 917 opened on one side of the fixing plate 916.

[0024] Furthermore, the top of the spring 903 is fixedly connected to the fixing block 904, the bottom of the spring 903 is fixedly connected to the connecting block 905, and the round rod 902 passes through the fixing block 904.

[0025] By adopting the above technical solution, the round rod 902 penetrates through the fixed block 904, so that the fixed block 904 will not be blocked by the round rod 902 when it moves.

[0026] Furthermore, the bottom of the round rod 902 is slidably connected to the first rack 906, the first rack 906 is meshed with the first gear 908, and the second gear 910 is meshed with the second rack 911.

[0027] By adopting the above technical solution, the first rack 906 is moved by the round rod 902, the first rack 906 drives the first gear 908, the first gear 908 drives the rotating rod 909 to rotate, the rotating rod 909 drives the second gear 910 to rotate, and the second gear 910 drives the second rack 911 to move, thereby completing the change of motion direction.

[0028] Furthermore, a first slider 907 is fixedly connected to one side of the first rack 906, and a second slider 912 is fixedly connected to the top of the second rack 911. Both the first slider 907 and the second slider 912 are "T" shaped, and the first slider 907 and the second slider 912 are slidably connected to the connecting shell 901.

[0029] By adopting the above technical solution, and through the T-shaped structure design of the first slider 907 and the second slider 912, the first rack 906 and the second rack 911 can remain stable during movement.

[0030] Furthermore, both the third slider 915 and the sliding groove 917 on the fixed plate 916 are "T" shaped, and the third slider 915 is slidably connected to the sliding groove 917 on the fixed plate 916.

[0031] By adopting the above technical solution, the groove 917 on the fixed plate 916 ensures that the third slider 915 slides only along the preset trajectory.

[0032] Furthermore, a protrusion is provided on the other side of the pressure plate 918.

[0033] By adopting the above technical solution, when the pressure plate 918 completes its rotation, the protrusions on its surface achieve reliable locking of the wire harness through mechanical interference, effectively preventing wire harness displacement.

[0034] Working principle: In use, the operator places the terminal in the second groove 11 on the fixed mold 5 and the wire harness in the first groove 10 on the placement seat 4, ensuring that the exposed end of the wire harness is on the terminal. Then, the hydraulic push rod 6 is activated, extending downwards from the second fixed seat 7 and the moving mold 8. The fixed block 904 on the second fixed seat 7 pushes the round rod 902 to move via the spring 903. The round rod 902 then drives the first rack 906 to move, which in turn drives the first slider 907 to slide on the connecting shell 901. Simultaneously, the first rack 906 drives the first gear 908 to rotate, which in turn drives the rotating rod 909 to rotate. The rotating rod 909 then drives the second gear 910 to rotate, which in turn drives the second rack 911 to move. The second slider 912 slides on the connecting shell 901. At the same time, the second rack 911 pushes the connecting seat 913 to move. The connecting seat 913 then pushes the moving seat 914 to move. The moving seat 914 then pushes the third slider 915 to slide in the groove 917 on the fixed plate 916. At the same time, it also pushes the pressure plate 918 to rotate until the protrusion on the pressure plate 918 presses down on the wire harness located in the first groove 10 on the placement seat 4. At this time, the round rod 902 can no longer be pushed to move. However, the hydraulic push rod 6 continues to extend. Since the round rod 902 passes through the fixed block 904, the fixed block 904 will not be blocked by the round rod 902 when it moves. Therefore, the fixed block 904 will continue to move downward to squeeze the spring 903 until the moving mold 8 and the fixed mold 5 close and press the terminal and wire harness together.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
