NO and OFF marks 105 are arranged at the upper and lower positions of the test hole 101. During testing, the mark 105 and the light ring 201 on the shift switch 2 are normally switched. When the detected power distribution box is fault-free, the light ring 201 is on when the shift switch 2 is turned to NO. If the light ring 201 is not on when the shift switch 2 is turned to NO, the power distribution box is defective. Multiple test holes 101 are arranged on the tool support 1, and multiple positions of the power distribution box can be tested simultaneously to ensure that the power distribution box is fault-free and improve the test efficiency and test quality.

[0006] The bottom of the long side of the tooling bracket 1 is provided with a foot extension 103, and the foot extension 103 is provided with a fixing hole 104. The tooling bracket 1 can be fixed on the table through the foot extension 103 and the fixing hole 104 to ensure the stability of the device during testing.

[0007] The short side of the tooling bracket 1 is provided with a semicircular groove 102 , through which the test workpiece and the power harness can pass, thereby ensuring the stable use of the tooling bracket 1 .

[0008] The pins 202 include the positive and negative input positions of the light ring 201 and the on / off positions of the shift switch 2 , and the corresponding positions are connected to the power supply and the distribution box.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model provides a plurality of test holes on the test workpiece. During the test, the distribution box under test is connected to the test distribution box through the shift switch to control the operation of the distribution box. The distribution box can drive the light ring switch through the shift of the shift switch to indicate that the product is good, otherwise it is a defective product. The components and circuits at the corresponding positions should be detected. The test tooling can test the circuit conditions at multiple positions on the distribution box at the same time to ensure that the factory distribution box is fault-free. According to the specifications of the distribution box, the corresponding multiple positions are selected to test whether a fault occurs, thereby improving the test efficiency.

[0017] In order to clarify the technical problems, technical solutions, implementation processes and performance demonstrations, the utility model is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are for explanation only. The utility model is not intended to limit the utility model. Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same figure numbers in the drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0018] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0019] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0020] like Figure 1-Figure 4 As shown, a vehicle distribution box test tool comprises a tool support 1 and a shift switch 2. The tool support is a hollow shell structure with a rectangular bottom opening. Two rows of multiple test holes 101 are arranged on the upper surface of the tool support 1. A light ring 201 is installed on the shift switch 2. A pin 202 is arranged at the bottom of the shift switch 2. Each test hole 101 on the upper surface of the tool support 1 is provided with a shift switch 2. NO and OFF marks 105 are arranged at the upper and lower positions of the test hole 101. During the test, the mark 105 corresponds to the normal switch of the light ring 201 on the shift switch 2. When the detected distribution box is fault-free, the light ring 201 is on when the shift switch 2 is turned to NO. If the light ring 201 is not on when the shift switch 2 is turned to NO, the distribution box is defective. Multiple test holes 101 are arranged on the tool support 1, and multiple positions of the distribution box can be tested at the same time to ensure that the distribution box is fault-free and improve the test efficiency and test quality.

[0021] The bottom of the long side of the tooling bracket 1 is provided with a foot extension 103, and the foot extension 103 is provided with a fixing hole 104. The tooling bracket 1 can be fixed on the table through the foot extension 103 and the fixing hole 104 to ensure the stability of the device during testing.

[0022] The short side of the tooling bracket 1 is provided with a semicircular groove 102 , through which the test workpiece and the power harness can pass, thereby ensuring the stable use of the tooling bracket 1 .

[0023] The pins 202 include the positive and negative input positions of the light ring 201 and the on / off positions of the shift switch 2 , and the corresponding positions are connected to the power supply and the distribution box.

[0024] When in use, the toggle switch 2 with the light ring 201 is set in the test hole position on the tooling bracket 1, and the corresponding pin position on the toggle switch is connected according to the actual electrical schematic diagram. 24V positive and negative are supplied externally, and then the toggle switch is turned on to control the relay inside the distribution box to be attracted. The fuse at the rear end of the relay inside the corresponding distribution box outputs 24V positive to the light ring 201 of the corresponding pin, and the other end of the light ring 201 is connected to 24V negative. At this time, the light ring will light up, indicating that the output of the pin is normal. If it is not lit, check the corresponding devices and circuits. This is convenient for production staff to detect and reduce the output of defective products.

[0025] The above shows and describes the basic principle, main features and advantages of the utility model.
