[0002] Low - voltage wire harnesses usually refer to wire harnesses used to transmit low - voltage signals and supply power, generally with a voltage range between 12V and 24V. They are mainly used to connect various sensors, actuators and other electronic components in automobiles and are an important part of the automobile circuit.
[0003] The low - voltage wire harness needs to be connected to electrical equipment or other conductors to play its role. Directly inserting the wire into the terminal or other connectors is likely to cause looseness and poor contact, thus bringing circuit failures or safety risks. Therefore, auxiliary tools are needed to complete the wiring by crimping the wire harness.
[0004] Some wire harnesses are crimped and wired to the terminals during the assembly line construction. However, in some inevitable working sites, it is necessary to wire one or more low - voltage wire harnesses separately, and a convenient and fast wiring device is required. Therefore, it is necessary to design a low - voltage wire harness wiring device that uses a handheld device to automatically crimp the wire harness and the terminal to complete the wiring, which is convenient for crimping and wiring the low - voltage wire harness that needs to be connected to the terminal separately and is applicable to wire harnesses of different specifications.

[0027] Working principle: When the present utility model is in use, the user first inserts the terminal on the surface of the low-voltage wire harness. Then, hold the wiring device with one hand and place the terminal between the two pressing heads 7 with the other hand. Then press the switch 19. At this time, the motor 17 starts to operate, and then the second bevel gear 18 rotates, so that the second bevel gear 18 drives the first bevel gear 16 to rotate. At this time, the threaded rod 10 rotates in the inner cavity of the main body case 1, and at the same time, the threaded sleeve 11 moves upward on the surface of the threaded rod 10. At this time, the two rotating plates 4 move away from each other, and the two arc-shaped plates 5 drive the pressing heads 7 to press the terminal. Then release the switch 19, and at this time the wire harness wiring is completed. Then press the switch 19 again to make the two pressing heads 7 move away from each other and directly remove the wire harness. If the initial diameters of the terminal and the wire harness are larger than the distance between the two pressing heads 7, the switch 19 can be pressed first to adjust the distance between the two pressing heads 7. The connection control between the above switch 19 and the motor 17 is prior art and will not be elaborated here. It can achieve the purpose of facilitating the crimping connection of the low-voltage wire harness that needs to be connected to the terminal alone and is applicable to wire harnesses of different specifications.
[0028] In summary, for the low-voltage wire harness wiring device, through the combined use of the motor 17 and the switch 19, the second bevel gear 18 drives the first bevel gear 16 to rotate, and then the threaded rod 10 rotates. Through the combined use of the threaded rod 10 and the threaded sleeve 11, the distance between the two rotating plates 4 can be changed, and then the distance between the two crimping heads 7 is changed, thereby completing the wiring. It can achieve the purpose of facilitating the crimping connection of the low-voltage wire harness that needs to be individually connected to the terminal, and is applicable to wire harnesses of different specifications.
