The test interface 10 and the socket 20 are integrated on a panel of the plug wire tester. The test interface 10 is an interface adapted to one end of a connector of a plug wire to be tested. The socket 20 is a mains socket 20 for providing a test current. Therefore, during testing, the connector end of the plug wire can be plugged into the test interface 10, and the plug end of the plug wire can be plugged into the socket 20, so that the plug wire to be tested is connected to the tester of the embodiment.

In order to control the supplied mains current, the socket 20 is also connected to the controller 40, and a power switch 90 and a transformer 91 are provided between the socket 20 and the controller 40. Wherein, the power switch 90 is used for controlling the on-off of the mains supply; the transformer 91 is used for reducing the input voltage to achieve the actual test requirement.

Each test module is arranged in parallel between the test interface 10 and the socket 20 and is connected or disconnected through the contactor 30; an on-off test line 80 is further formed between the test interface 10 and the socket 20 through the contactor 30, and the on-off test line 80 is arranged in parallel with the withstand voltage test module 50, the resistance test module 60 and the insulation test module 70. Thus, by switching the contactor 30, the plug wires connected between the test interface 10 and the socket 20 can be subjected to the comprehensive test of voltage resistance, insulation, and on-off in order.

In order to switch on/off the test circuit 80 and each test module, the contactor 30 includes a plurality of switch KM1-KM4 arranged in parallel, any switch is connected in series between the test interface 10 and the socket 20, and each test module is connected or disconnected through a corresponding switch. That is, when the switch is closed, the test circuit where the corresponding test module is located is kept in communication, which can perform a corresponding test on the plug wire, and feedback the test result to the controller 40 for displaying the test result. Therefore, each performance test of the plug wire can be completed by sequentially opening and closing the change-over switch.

The withstand voltage test module 50 includes: a high-pressure plate 51 and a high-pressure bag 52; the high pressure plate 51 is connected to the controller 40 and the high pressure bag 52 is connected to a corresponding interface on the contactor 30. The high voltage pack 52 is used for providing a high voltage, and the high voltage board 51 is used for judging whether the plug wire has electric leakage or not, and whether the electric leakage exceeds a set value or not, and if so, bad prompt is given. Thus, the internal pressure test of the plug cord can be achieved by the above-described high-voltage board 51 and high-voltage package 52. It should be noted that, the high-pressure plate 51 and the high-pressure bag 52 of the present embodiment may be existing products, for example, those produced by siemens may be selected.

Further, the voltage withstanding test module 50 is also capable of performing an external voltage test on the plug. At this time, the withstand voltage test module 50 further includes a left die holder 53 and a right die holder 54. The left die holder is located at one side of the socket 20, the right die holder 54 is located at the other side of the socket 20 relative to the left die holder 53, and the left die holder 53 and the right die holder 54 are respectively driven by an air cylinder to perform die assembly. The cylinder is connected with the controller 40, and a conductive sponge is also arranged on the die surface of any die holder.

Thus, when the left die holder 53 and the right die holder 54 are clamped, the socket 20 of the plug is clamped between the left die holder 53 and the right die holder 54, and is then in the electric field formed by the two conductive sponges. At this time, according to whether the plug wire is leaked in the corresponding electric field, the plug wire is subjected to external voltage test. In addition, in order to control the progress of the external pressure test, the cylinders driving the left die holder 53 and the right die holder 54 are controlled by a pedal 55 switch. Thus, when a tester steps on the pedal 55, the left die holder 53 and the right die holder 54 can be controlled to be clamped; when the pedal 55 is released, the socket 20 of the plug can be disconnected from the external test field.

The resistance test module 60 includes a resistance meter; a resistance meter is connected between the contactor 30 and the controller 40. Thus, after the switch of the circuit in which the resistance test module 60 is located is closed, the test value of the plug can be displayed through the resistance meter.

The insulation test module 70 includes: an insulating plate 71 and an insulating table 72; the insulating sheet 72 is connected to the contactor 30 through an insulating sheet 71, and the insulating sheet 71 is also connected to the controller 40. The insulating plate 71 is used for judging whether the insulation resistance of the plug is smaller than a set value, and if so, an alarm is given. The insulating table 72 is correspondingly displayed. Thus, when the switch of the line where the insulation test module 70 is located is closed, the insulation meter 72 can display the test value of the plug. It should be noted that the insulating board 71 of the present embodiment may be an existing product, for example, an insulating board product manufactured by deep electronic technology may be selected.

As described above, the on-off test line 80 is constituted by the corresponding switch among the test interface 10, the socket 20, and the contactor 30. Thus, after the switch of the on-off test line 80 is closed, it can be detected whether the plug is normally turned on.

The controller 40 is used to control the closing or opening of the various switches in the contactor 30. The controller 40 is also configured to receive test results from the test modules and receive signals from whether the on/off test line 80 is conductive. And feeding back the test result according to the received test result and the signal whether to conduct. The controller 40 employed in this embodiment is a loose PLC controller 40 of the type FP0C 32.

In order to realize feedback of test results, a plurality of indicator lamps 100 are further arranged on the panel of the plug wire tester, an indicator lamp 100 is connected in series in the on-off test circuit 80 and each test module, and the indicator lamps 100 are further connected with the controller 40. Either indicator light 100 has a red light-on state or a green light-on state, so that the controller 40 controls the light-on state of the indicator light 100 by judging whether the test result satisfies a set threshold value and whether a turn-on signal is received. That is, the red light of the indicator lamp 100 indicates the product NG, and the green light of the indicator lamp 100 indicates the product OK.
