[0035] The box body 1 comprises a main box 11 and a box cover 12, and a door buckle type quick clamp 13 is arranged between the main box 11 and the box cover 12. The fixed buckle of the door buckle type quick clamp 13 is fixed on the side wall of the main box 11, and the hasp of the door buckle type quick clamp 13 can be clamped below the fixed buckle. When the door buckle type quick clamp 13 is closed, the box cover 12 is tightly attached to the main box 11, and the box cover 12 is detachably connected to the main box 11.
[0036] A partition plate 14 is arranged in the main box 11, and the partition plate 14 divides the main box 11 into a first box chamber 15 and a second box chamber 16. The first box chamber 15 is larger. The battery pack 2 is arranged in the first box chamber 15, and a plurality of transverse ventilation slots 17 are arranged on the side wall of the first box chamber 15. The heat generated when the battery pack 2 operates is discharged through the ventilation slots 17, thereby improving safety. Further, the box body 1 is made of insulating material, which effectively isolates the electric charge and improves the safety in use.
[0037] The negative electrode of the battery pack 2 is further connected to a grounding wire 3, which extends out of the box body 1 through the ventilation slot 17 and is grounded, thereby improving the safety in use of the battery pack 2.
[0038] A positive electrode terminal 6 and a negative electrode terminal 7 are further arranged on the partition plate 14, and the positive electrode terminal 6 and the negative electrode terminal 7 are both communicated to the first box chamber 15 and the second box chamber 16. The positive electrode of the battery pack 2 is connected to the positive electrode terminal 6 through a wire, and the negative electrode of the battery pack 2 is connected to the negative electrode terminal 7 through a wire.
[0039] Further, referring to Figure 2 and Figure 3 , the overcurrent protection device 4 can be a circuit breaker and is fixed in the second box chamber 16. The shortcut circuit interface 5 is arranged on the side wall of the main box 11 and is communicated to the second box chamber 16. The shortcut circuit interface 5 comprises a positive electrode interface 51 and a negative electrode interface 52. The positive electrode interface 51 and the negative electrode interface 52 both comprise a connecting column 53 and a knob type interface 54. A socket 55 matched with a banana plug is arranged on the outer end surface of the knob type interface 54. When testing, the measured sample can be inserted into the socket 55 through the banana plug, or the metal wire of the measured sample can be wound on the connecting column 53 and is fixed by screwing the knob type interface 54, so as to be connected between the positive electrode interface 51 and the negative electrode interface 52.

[0042] A through hole 18 is further formed on the side wall of the main box 11, and the reset switch 41 of the over-current protection device 4 is exposed through the through hole 18. When the current overflows, whether the over-current phenomenon occurs can be determined by the state of the reset switch 41. If the reset switch 41 of the over-current protection device 4 jumps off, when there is no abnormality after checking, the reset switch 41 is pushed to reset when the battery box is used again.
[0043] Further, in order to facilitate the movement of the battery box during the test, handles 10 are arranged on a pair of opposite side walls of the main box 11, so that the workers can carry the battery box.
[0044] The implementation principle of the battery box for electromagnetic compatibility test according to the embodiment of the application is as follows: when the tested sample is tested, the positive of the tested sample is connected with the positive terminal 51 of the shortcut line interface 5, the grounding wire 3 is grounded, and the negative of the tested sample is connected with the negative terminal 52 of the shortcut line interface 5. Then, the battery pack 2 supplies power to the tested sample.
[0045] During the test, if the current overflows, the reset switch 41 of the over-current protection device 4 jumps off, and the power supply of the battery pack 2 is disconnected. During the test, the workers can observe the running state of the circuit through the ammeter 8 and the voltmeter 9. After checking the abnormality, the reset switch 41 is pulled back to use again.
[0046] Meanwhile, the battery pack 2 is installed in the box body 1, the connection line of the battery pack 2 is stable and not easy to fall off to cause sparking, and the box body 1 effectively isolates the electric charge, thereby improving the safety during the test.
