Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-4 shown, a new tool with the function of quickly testing OBD diagnostic cables includes 1. An OBD socket 2 is provided on one side surface of the test board 1, a 24-pin connector 3 is provided on one side surface of the test board 1, a 3mm light-emitting diode 4 is provided on one side surface of the test board 1, a 330-ohm color ring resistor 5 is provided on one side surface of the test board 1, a button 6 is provided on one side surface of the test board 1, and an installation mechanism 7 is provided on one side surface of the test board 1. A power supply module 8 is provided inside the installation mechanism 7; the power supply module 8 is connected to the OBD socket 2, the 24-pin connector 3, the 3mm light-emitting diode 4, the 330-ohm color ring resistor 5, and the button 6 in sequence through electrical circuits.

[0020] During the test, first insert the two ends of the cable into the 24-pin connector 3 and the OBD socket 2 respectively, and press the button 6. At this time, each of the 20 buttons 6 corresponds to all the pins respectively. If the pins are normal and there is no problem, then the 3mm light-emitting diode 4 corresponding to the button 6 will light up. Pressing all the buttons 6 can check whether all the pins are good. The internal wiring diagram is as Figure 2 , and if there is a fault in the pin, it can be clearly known which pin has a problem, which is convenient for maintenance. Such a maintenance tool is convenient to use and more convenient to troubleshoot faults. Secondly, the 330-ohm color ring resistor 5 can stabilize the resistance value of the circuit, limit the current of the circuit, and protect the circuit. In this way, a new tool with the function of quickly testing OBD diagnostic cables is completed.

[0021] The number of 3mm light-emitting diodes 4, 330-ohm color-ring resistors 5, and buttons 6 are all set to be multiple. The 3mm light-emitting diodes 4 and 330-ohm color-ring resistors 5 are arranged at equal intervals on one side surface of the test board 1, and the buttons 6 are arranged at equal intervals on the other side surface of the test board 1. The buttons 6 are connected to the 24-pin connector 3 one by one. There is a one-to-one correspondence between the OBD socket 2 and the 3mm light-emitting diode 4. The installation mechanism 7 is composed of a spring 702, a positive electrode plate 703, a negative electrode plate 704, a pull rod 706, a mounting bracket 701, and a positioning plate 705. The positioning plate 705 is slidably connected to the inside of the installation mechanism 7. Springs 702 are fixedly connected to both sides of the inner wall of the installation mechanism 7. One end of the spring 702 is fixedly connected to the positioning plate 705. A pull rod 706 is fixedly connected to one side of the positioning plate 705. The pull rod 706 drives the positioning plate 705 to slide inside the installation mechanism 7 by advancing inside the mounting bracket 701, further squeezing and fixing the power module 8 inside, and further driving the positive electrode plate 703 and the negative electrode plate 704 to be electrically connected to the whole of the power module 8 respectively.

[0022] In summary, the present utility model has the following working principle: When in use, pull the pull rod 706 to drive the positioning plate 705 to slide to one side. At this time, the power module 8 can be placed inside the installation mechanism 7. Then release the pull rod 706. Under the elastic action of the spring 702, drive the positioning plate 705 to rebound and reset, so that the positive electrode plate 703 and the negative electrode plate 704 are respectively in electrical contact with the positive and negative poles of the power module 8. At this time, the staff can perform the detection work. Plug the two ends of the cable to be detected into the OBD socket 2 and the 24-pin connector 3 respectively for electrical connection. Then press the corresponding button 6. The corresponding light-emitting diode 4 in the connected circuit will light up. Lighting up indicates that the single circuit in the cable passes the detection. Similarly, if the corresponding button 6 is pressed and the corresponding light-emitting diode 4 is defective, it means that the single circuit is not connected and cannot pass the detection. Thus, the specific circuit problem can be accurately understood, which is convenient for precise repair. Such a maintenance tool is convenient to use and more convenient for troubleshooting. Secondly, the 330-ohm color-ring resistor 5 can stabilize the resistance value of the circuit, limit the current of the circuit, and protect the circuit. In this way, a new tool with the function of quickly testing the OBD diagnostic cable is completed.
