This step can only be completed manually. It is very inconvenient to test multiple wires of the terminal wire one by one until a faulty wire is detected, which consumes a lot of time and manpower.

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] Reference Figures 1 to 3 The utility model proposes a terminal wire testing device, including a test board 1 and a plurality of detection units 5. The test board 1 has an observation surface 11, and the observation surface 11 is provided with a first plug-in portion 2 and a second plug-in portion 3. The first plug-in portion 2 and the second plug-in portion 3 are provided with a plurality of plug interfaces 4, and the second plug-in portion 3 is electrically connected to an external power supply; the plurality of detection units 5 are all arranged on the observation surface 11, and are electrically connected to the plurality of plug interfaces 4 of the first plug-in portion 2 in turn, and the detection units 5 are also electrically connected to the external power supply, so that when the two plug-in portions are inserted at both ends of the terminal wire, a plurality of test loops are formed to test each wire in the terminal wire.

[0025] It can be understood that the first plug-in part 2, the second plug-in part 3 and the detection unit 5 are all arranged on the observation surface 11 of the test board 1, so that the test results of the terminal wire can be observed from this surface. The two ends of the terminal wire are respectively plugged into the first plug-in part 2 and the second plug-in part 3, and since the terminal wire is composed of multiple wires, the two plug-in parts are correspondingly provided with multiple plug interfaces 4, and the second plug-in part 3 is also connected to the power supply. When the terminal wire is plugged into the two plug-in parts, the current will flow from the second plug-in part 3 to the first plug-in part 2.

[0026] The detection unit 5 is used to measure whether a certain wire that constitutes the terminal line is conductive. In this example, an indicator light 6 and a lever switch 7 are used to form the detection unit 5. The number of the detection units 5 is consistent with the number of the plug interfaces 4 and is connected one by one with the plug interfaces 4 of the first plug-in part 2. At the same time, the detection unit 5 is also connected to the power supply to form a complete circuit of power supply - terminal line - detection unit 5 - power supply. Through the above setting, each detection unit 5 can detect each wire in the terminal line. By observing whether the indicator light 6 in the detection unit 5 is on, it can be determined whether the wire is conductive, which is very convenient.

[0027] Reference Figures 1 to 2 In one embodiment of the present application, each detection unit 5 includes an indicator light 6 and a lever switch 7, the indicator light 6 is electrically connected to the plug interface 4 of the first plug-in portion 2; the lever switch 7 is electrically connected to the indicator light 6 and an external power supply.

[0028] It can be understood that the detection unit 5 is composed of an indicator light 6 and a lever switch 7. The indicator light 6 is connected to the plug interface 4, and the lever switch 7 is connected to the indicator light 6 and the power supply, forming a complete circuit of power supply - terminal wire - indicator light 6 - lever switch 7 - power supply. When the terminal wire is inserted into the plug-in part and the switch is closed, by observing whether the indicator light 6 is on, it can be determined whether the wire is conductive.

[0029] The setting of the lever switch 7 is to facilitate the on-off control of the circuit, and secondly, it can also play a certain protective role for the indicator light 6. Since the rated current of the indicator light 6 is usually relatively small, and a large current is usually generated at the moment when the terminal wire is inserted into the plug-in part to form a circuit, it is easy to burn out the indicator light 6. Therefore, setting the lever switch 7 and controlling the on-off of the circuit by the lever switch 7 can play a certain protective role for the indicator light 6.

[0030] Reference Figures 1 to 2 In one embodiment of the present application, a plurality of detection units 5 are linearly distributed on the observation surface 11 .

[0031] It can be understood that since the detection units 5 are sequentially connected to the plug interfaces 4 of the first plug-in portion 2, the detection units 5 are linearly arranged on the observation surface 11, and the arrangement order of the detection units 5 is consistent with the order of the plug interfaces 4, so that it is possible to clearly see which wire of the terminal wire is being tested by the detection unit 5, which is convenient for the user to grasp the detection results. In this example, the detection units 5 are also arranged equidistantly, making the board surface more neat and beautiful.

[0032] Reference Figures 1 to 2 In one embodiment of the present application, a fixing plate 8 is further provided on the observation surface 11 , and the lever switches 7 are all in contact with the fixing plate 8 .

[0033] It can be understood that the lever switch 7 is fixed on the test board 1. After being toggled for many times, the lever switch 7 may become loose and cause damage to the test circuit, thus affecting the test result. The fixing plate 8 is provided to support the lever switch 7 and provide support force when it is toggled, so that the connection between the lever switch 7 and the test board 1 is not easy to loosen and is more firm. It can also make the arrangement of the lever switch 7 in the same straight line, which is more neat and beautiful.

[0034] Reference Figures 1 to 3 In one embodiment of the present application, the test board 1 is provided with two support plates 9 on a side facing away from the observation surface 11 .

[0035] It can be understood that the test board 1 has wires connected to the test circuit on the back of the observation surface 11. These wires are relatively fragile and touching them should be minimized. The support plate 9 is provided to support the test board 1 so that there is space between the test board 1 and the work surface, and the wires on the back of the test board 1 will not be directly touched, which plays a good protective role. In addition, the support plate 9 prevents the test board 1 from directly contacting the work surface, thereby reducing the wear and tear on the test board 1 and extending its service life.

[0036] Reference Figures 1 to 3 In one embodiment of the present application, a battery holder 91 is provided on the side wall of the support plate 9, a battery 92 is provided in the battery holder 91, and the positive and negative poles of the battery 92 are electrically connected to the second plug-in portion 3 and the lever switch 7 respectively.

[0037] It can be understood that the entire test device is powered by battery 92, which has the following advantages: portability and flexibility. It uses battery 92 for power without relying on a power socket, so it is more portable and the user can use the test device anytime and anywhere. Battery 92 power supply makes the layout and placement of the device more flexible and free, and is not restricted by the power cord. The device can be more flexibly arranged in any position; it has good emergency response. Battery 92 power supply will not be affected by power outages. When the power is interrupted or fails, it can also ensure the normal operation of the device, thereby avoiding problems such as production interruptions caused by power outages; it reduces the use of power cords. Using battery 92 for power supply can reduce the use of power cords and simplify the wiring of the device.

[0038] The technical solution of the utility model is to set multiple groups of detection units 5 on the test board 1, each group of detection units 5 includes an indicator light 6 and a lever switch 7, and forms a loop with a single line in the terminal line. By toggling the lever switches 7 of the multiple detection units 5, each line of the terminal line can be accurately detected, which is convenient, fast, time-saving and labor-saving.
