In order to ensure the reliability of vehicle power supply and evaluate the power consumption of the entire vehicle, it is necessary to accurately, reliably and efficiently test the working current of electrical appliances. In the prior art, current clamps are generally used to detect loop currents. However, current clamps are large in size, occupy a lot of space, and it is difficult to collect currents from multiple adjacent loops. In addition, the layout of the current clamp is difficult to fix. When the vehicle is in motion, the current clamp is easy to shift, fall off or hit the components on the vehicle, making current testing difficult.

[0057] In one possible implementation, Figure 4 A schematic diagram of a current detection device according to another embodiment of the present invention is shown in FIG. Figure 4 A first slot 24 and a second slot 25 may be provided on the connecting portion 2, and metal springs may be provided in the first slot 24 and the second slot 25. At least two conductive posts may be provided on the power distribution box 300, and the conductive posts may be part of the circuit in the power distribution box 300.

Such two conductive posts may be plugged into the corresponding first slot 24 and second slot 25, and may be able to reliably contact the corresponding metal springs in the first slot 24 and second slot 25, so that the circuit in the power distribution box 300 may be effectively connected in series between the power supply 200 and the electrical equipment.

[0058] In a possible implementation, the current detection device may not be connected to the power distribution box 300 , but may be connected to a terminal of the power supply 200 . Figure 5 A schematic diagram of a current detection device provided in another embodiment of the present application connected in series in a power circuit, referring to Figure 5 , taking the power source 200 as a power battery in an electric car as an example, the battery has a terminal 210, and the terminal 210 can be electrically connected to an electrical device to supply power to the electrical device. The terminal 210 can have multiple terminals, such as a positive terminal and a negative terminal. The current detection device can be connected to one terminal; or the current detection device can be connected to multiple terminals, which is conducive to more accurate detection of the current in the power circuit. Among them, the electrical device has a jack or other structure that matches the terminal, so that the electrical device and the power source 200 can be effectively electrically connected through the cooperation of the jack and the terminal. In this embodiment, Figure 6 A schematic diagram of a current detection device according to another embodiment of the present invention is shown in FIG. Figure 6The first connecting pin 21 includes a connecting hole 211, and the connecting hole 211 is used to be set on the terminal of the power supply 200, and an electrical connection can be formed between the connecting hole 211 and the terminal 210. The second connecting pin 22 includes a connecting head 221, and the connecting head 221 is used to be inserted into the socket of the electrical device, and an electrical connection can be formed between the connecting head 221 and the socket. When detecting the power circuit between the power supply 200 and the electrical device, the socket on the electrical device can be separated from the corresponding terminal on the power supply 200, and then the connecting hole 211 on the first connecting pin 21 is set on the terminal of the power supply 200, and the connecting head 221 on the second connecting pin 22 is inserted into the socket on the electrical device, so that the current detection device can be connected in series between the power supply 200 and the electrical device, and the current in the power circuit can be detected. Thus, the current detection device can be directly matched and electrically connected with the power supply 200 by the connection part 2 having the above structure, so that the current detection device can be easily connected in series between the power supply 200 and the electrical equipment. Among them, the structural dimensions of the connection hole 211 are similar to the structural dimensions of the above-mentioned jack on the electrical equipment, and the structural dimensions of the connection head 221 are similar to the structural dimensions of the above-mentioned terminal on the power supply 200, so that the connection part 2 can be reliably matched and connected with the power supply 200 and the electrical equipment, ensuring the effectiveness of the electrical connection.

[0059] In one possible implementation, referring to Figure 6 The first connection pin 21 may be provided with a slot 212, one end of the slot 212 is connected to the connection hole 211 on the first connection pin 21, and the end of the slot 212 away from the connection hole 211 passes through the first connection pin 21. The slot 212 can separate a part of the first connection pin 21 into a first clamping arm 213 and a second clamping arm 214, so that the first clamping arm 213 and the second clamping arm 214 can move closer to or farther from each other when subjected to external force, thereby making the diameter of the connection hole 211 larger or smaller, so as to facilitate the disassembly and assembly of the connection hole 211 and the terminal, and when the first clamping arm 213 and the second clamping arm 214 move closer to each other, the inner wall of the connection hole 211 can reliably contact the terminal, thereby ensuring the effectiveness of the electrical connection.

[0060] In one possible implementation, referring to Figure 6The first clamping arm 213 is provided with a first locking hole 215, and the second clamping arm 214 is provided with a second locking hole. The first clamping arm 213 and the second clamping arm 214 are moved closer to or farther from each other through the cooperation of the first locking hole 215, the second locking hole and the first connecting member. One of the first locking hole 215 and the second locking hole can be a plain hole, and the other can be a threaded hole. The first connecting member can be a screw, and the screw can be locked in the threaded hole after passing through the plain hole. By adjusting the depth of the screw screwed into the threaded hole, the distance between the first clamping arm 213 and the second clamping arm 214 can be adjusted, so that the diameter of the connecting hole 211 can be adjusted. For example, when the first clamping arm 213 and the second clamping arm 214 move away from each other, the diameter of the connection hole 211 can be increased, thereby facilitating the disassembly and assembly between the connection hole 211 and the terminal; when the first clamping arm 213 and the second clamping arm 214 move closer to each other, the diameter of the connection hole 211 can be reduced, thereby ensuring that the inner wall of the connection hole 211 is in reliable contact with the terminal and ensuring the effectiveness of the electrical connection. In some other embodiments, the first locking hole 215 and the second locking hole can both be light holes, and the screw can be fastened with the nut after passing through the light holes on the first locking hole 215 and the second locking hole in turn. By adjusting the depth of the screw screwed into the nut, the distance between the first clamping arm 213 and the second clamping arm 214 can be adjusted, thereby achieving the direct size adjustment of the connection hole 211.
