Description

Technical Field

[0001] The invention relates to the technical field of tractor light and ABS detection, in particular to a tractor light signal and ABS electrical interface function detector. Background Art

[0002] The tractor's light signal and ABS electrical interface is an important part to ensure the normal operation of the trailer's light signal and ABS braking system. It accurately transmits the driver's turn signal, brake light, clearance light, reverse light, and hazard warning light switch signal instructions to the trailer. Whether the tractor's light signal and ABS electrical interface work properly will seriously affect the driving safety of the trailer train.

[0003] At present, inspectors usually use a multimeter to test the tractor's light signal and ABS electrical interface. However, since there are many pins on the tractor's light signal and ABS electrical interface, the efficiency of using a multimeter and a test light for testing is low. In addition, such testing places high demands on the inspectors, who need to deliberately remember the electrical function of each pin of the tractor's light signal and ABS electrical interface. This is not only troublesome, but also prone to errors during the testing process, resulting in excessive testing efficiency and affecting the debugging and production progress of the traction vehicle. Summary of the invention

[0004] The present invention has the advantages of high detection efficiency and low requirements on detection personnel.

[0005] In order to solve the problems in the above background technology, the present invention is implemented by the following technical solutions:

[0006] A tractor light signal and ABS electrical interface function detector, comprising a housing, an ABS detection plug and a light signal detection plug arranged on the housing, wherein the ABS detection plug matches the ABS signal interface socket, and the light signal detection plug matches the light signal interface socket;

[0007] The light signal detection plug is connected in parallel with a plurality of light signal detection indicator lights, the ABS detection plug is connected in parallel with a plurality of power control switches, and a power indicator light is connected in series between the plurality of power control switches and the ABS detection plug;

[0008] Connect the light signal detection plug to the light signal interface socket, and when the light signal to be detected is qualified, the corresponding indicator light is normally lit;

[0009] Connect the ABS detection plug to the ABS signal interface socket, turn on the corresponding power control switch, and when the function to be detected is qualified, the corresponding power indicator light will light up normally.

[0010] As a further explanation of the invention: the light signal detection indicator lights are arranged in one-to-one correspondence with the light signals to be detected.

[0011] As a further description of the invention: the power control switch includes an ABS solenoid valve power control switch, an ABS fault indicator light control switch and an ABS controller power control switch.

[0012] As a further explanation of the invention: there are two power indicator lights, which are respectively connected in series between the ABS solenoid valve power control switch and the ABS detection plug, and between the ABS controller power control switch and the ABS detection plug.

[0013] As a further explanation of the invention: instructions for use are provided on the shell.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. When the tractor's light signal and ABS electrical interface functions need to be tested, connect the light signal detection plug to the tractor's light signal interface socket, and connect the ABS detection plug to the tractor's ABS signal interface socket to complete the connection between the detector and the tractor, and then turn on the left and right turn lights, left and right clearance lights, left and right brake lights, and left and right reverse lights in sequence. If the corresponding light signal detection indicator lights of the detector can light up synchronously, the test is qualified. If the corresponding light signal detection indicator lights of the detector fail to light up synchronously, the test is unqualified and the vehicle circuit needs to be repaired;

[0016] After the light signal detection is completed, turn on the ABS controller power control switch on the tester. If the power indicator light connected in series with the ABS controller power control switch lights up normally, the detection is qualified. Otherwise, the detection is unqualified and the vehicle circuit needs to be repaired. Turn on the ABS solenoid valve power control switch of the tester. If the indicator light connected in series with the ABS solenoid valve power control switch lights up normally, the detection is qualified. Otherwise, the detection is unqualified and the vehicle circuit needs to be repaired. Turn on the ABS fault indicator light control switch of the tester. If the ABS fault indicator light on the instrument panel lights up normally, the detection is qualified. Otherwise, the detection is unqualified and the vehicle circuit needs to be repaired. Such detection not only has low requirements for detection personnel and simple operation, but also improves detection efficiency, reduces the probability of errors during detection, and ensures the debugging and production progress of traction vehicles.
