[0025] As shown in Figure 1 and Figure 2 The present embodiment provides a kind of whole vehicle high voltage signal rapid acquisition structure, comprising: connection wire harness 1, line splitter 2 and acquisition wire harness 3;One end of connection wire harness 1 is used to be electrically connected with power supply equipment, and the other end of connection wire harness 1 is used to be electrically connected with electric equipment;One end of acquisition wire harness 3 is connected to connection wire harness 1 via line splitter 2, and the other end of acquisition wire harness 3 is used to be externally connected with electric signal acquisition equipment 4.Such, connection wire harness 1 can be used as high voltage alternative wire harness to carry out electric signal transmission between power supply equipment and electric equipment, then line splitter 2 is configured in the middle section of connection wire harness 1 to connect acquisition wire harness 3, electric signal acquisition equipment 4 is connected outside using acquisition wire harness 3, and then electric signal acquisition is carried out without affecting normal connection of transmission line, avoid high voltage environment exposure of power supply equipment / electric equipment at wire connection, eliminate the risk of foreign matter entering power supply equipment / electric equipment and the safety hazard of personnel electric shock.

[0026] Specifically, as shown in Figure 1 and Figure 2As shown, the connection wire harness 1 in the embodiment can be made of the same cable as the high-voltage wire, both ends of the connection wire harness 1 are respectively provided with a connector 13 for electrical connection with the power supply device and the electrical device, and the model of the connector 13 is the same as the model of the connector at both ends of the original high-voltage wire; the wire distributor 2 can be a T-shaped wire clamp or a three-way wire distributor, the shell of the wire distributor 2 is an insulating shell and has a conductive structure and a shielding layer inside, which can realize the electrical connection between the connection wire harness 1 and the collection wire harness 3, and play a protective role of insulation, sealing and shielding at the connection position of the two; the connection wire harness 1 is cut in the middle section, and then the wire distributor 2 is fixed on the connection wire harness 1, so that the connection wire harness 1 is arranged in two of the three interfaces of the wire distributor 2, and one end of the collection wire harness 3 is introduced into the wire distributor 2 through the other interface of the wire distributor 2 and connected in parallel with the connection wire harness 1, that is, the manufacturing of the whole vehicle high-voltage signal rapid collection structure is completed. It can be understood that the specific structure and fixing mode of the wire distributor 2 and the specific connection mode of the connection wire harness 1 and the collection wire harness 3 in the wire distributor 2 can be referred to the prior art, which will not be described here.

[0027] During measurement, the original high-voltage wire between the power supply device and the electrical device is disconnected, both ends of the connection wire harness 1 are inserted and connected in series in the measured line, so that the connection wire harness 1 replaces the original high-voltage wire to electrically connect the power supply device and the electrical device of the high-voltage electrical device. At this time, the connection state of the connection wire harness 1 at the connection position of the power supply device or the electrical device is basically the same as that of the original high-voltage wire, which avoids the exposure of the power supply device / electrical device to the high-voltage environment at the wire connection position, eliminates the risk of foreign matter entering the power supply device / electrical device and the safety hazard of electric shock. Then, the collection wire harness 3 is connected to the electric signal collection device 4 (such as a power analyzer), and the corresponding electric signal can be collected, ensuring the effective test.

[0028] It can be understood that the above-described embodiment described with reference to the accompanying drawings is exemplary and is intended to explain one arrangement of the connection wire harness 1, and cannot be understood as a limitation of the present application. In other embodiments, one end of the connection wire harness 1 can be connected to the power supply device and the other end can be connected to the original high-voltage wire; or one end of the connection wire harness 1 can be connected to the electrical device and the other end can be connected to the original high-voltage wire; or the original high-voltage wire can be provided with a connector in the middle, and the connector is disconnected and connected to the connection wire harness 1 during testing. The two ends of the connection wire harness 1 can be connected in series in the measured line between the power supply device and the electrical device according to the specific use requirement, which will not be described here.

[0029] In some embodiments, as Figure 1As shown, the installation spacing is left between the splitter 2 and the end of the connection wire harness 1, and the splitter 2 is externally arranged independently of the power supply device or the electrical device based on the installation spacing. Specifically, the installation spacing is left between the series connection of the splitter 2 and any end of the connection wire harness 1, which can avoid the interference of the splitter 2 with the normal connection of the connection wire harness 1 and the corresponding power supply device or electrical device, and ensure the effective sealing of the power supply device / electrical device in the high-voltage environment at the connection of the connection wire harness 1.

[0035] In some embodiments, the positive signal connection terminal 311 and the negative signal connection terminal 321 can be respectively provided with an identification for showing the corresponding phase, for example, a "+" symbol is arranged on the outer surface of the positive signal connection terminal 311, and a "-" symbol is arranged on the outer surface of the negative signal connection terminal 321, so as to ensure that the positive signal connection terminal 311 and the negative signal connection terminal 321 can be conveniently and quickly plugged into the correct hole position.

[0036] In some embodiments, the positive signal connection terminal 311 and the negative signal connection terminal 321 can also be provided with different colors, for example, the positive signal connection terminal 311 is configured as red, and the negative signal connection terminal 321 is configured as black, so as to facilitate the identification of the phase of the collection wire harness 3.
