[0027] Reference Figure 1 , which shows a schematic structural diagram of a power output terminal of a power distribution unit for a charging device provided in an embodiment of the present application.

[0028] like Figure 1 As shown, an embodiment of the present application provides a power output terminal for a power distribution unit of a charging device, comprising:

[0029] The insulating member 10 and the conductive member 20 are arranged alternately along a first direction;

[0030] One end of the conductive member 20 is used to be connected to the output end of the power distribution unit of the charging device; the other end of the conductive member 20 is used to be connected to the charging interface.

[0031] Specifically, the insulating members 10 and the conductive members 20 are arranged alternately along the first direction, that is, a conductive member 20 is disposed between two adjacent insulating members 10. It is understandable that the insulating members 10 and the conductive members 20 can be connected by snap connection or by screw connection.

[0032] The conductive member 20 is used for power transmission between the output end of the power distribution unit of the charging device and the charging interface. Optionally, the conductive member 20 can be made of conductive materials such as copper bars or aluminum bars. It is understandable that the thickness, size, etc. of the copper bar or aluminum bar can be selected according to the power size of the power transmitted by the conductive member 20. It is also understandable that the number of conductive members 20 is the same as the number of output ends of the power distribution unit of the charging device.

[0033] The insulating member 10 is used to isolate adjacent conductive members 20 to prevent current from flowing through unexpected paths, thereby avoiding circuit short circuits and electric shock hazards. The insulating member 10 is a component made of insulating material, such as plastic, etc. It is understandable that the thickness and size of the insulating member 10 need to be selected and set according to safety regulations.

[0034] The power output terminal of the power distribution unit for the charging device provided in the embodiment of the present application is composed of an insulating part and a conductive part, has a simple structure, and the use of the insulating part can prevent short circuits and leakage between the conductive parts, thereby ensuring the safe operation of the charging system.

[0035] In one embodiment, the insulating member 10 has a first side surface 11 and a second side surface 12 that are adjacent to each other, and the first side surface 11 and the second side surface 12 form an L-shaped structure;

[0036] The conductive member 20 has the same structure as the insulating member 10;

[0037] The projection of the conductive member 20 along the first direction is located within the projection range of the first side surface 11 and the second side surface 12 of the insulating member 10 along the first direction.

[0038] Specifically, the insulating member 10 and the conductive member 20 both adopt an L-shaped structure, which can facilitate the connection between the output end of the power distribution unit of the charging device and the charging interface and the conductive member 20. It can also reduce the overall size of the insulating member.

[0039] The projection of the conductive member 20 along the first direction is located within the projection range of the first side surface 11 and the second side surface 12 of the insulating member 10 along the first direction, that is, the first side surface 11 and the second side surface 12 of the insulating member 10 are both protruded from the conductive member 20, and the protrusion height can be set according to the safety specification. This design can effectively complete the physical isolation of two adjacent conductive members. This implementation structure is not shown in the figure.

[0040] In one embodiment, the insulating member 10 has a first side surface 11 and a second side surface 12 disposed adjacent to each other, and the first side surface 11 and the second side surface 12 form an L-shaped structure;

[0041] The conductive member 20 has the same structure as the insulating member 10;

[0042] The first side surface 11 of the insulating member 10 is protruded from the conductive member 20;

[0043] The second side surface 12 of the insulating member 10 is arranged flush with the conductive member 20;

[0044] The power output terminal further includes an insulating sheet 30 , which is connected to the second side surface 12 of the insulating member 10 .

[0045] Specifically, the first side surface 11 of the insulating member 10 protrudes from the conductive member 20 , and the protruding height can be set according to safety regulations.

[0046] The second side surface 12 of the insulating member 10 is flush with the conductive member 20. It is understandable that if the insulating member 10 and the conductive member 20 are connected by snap-fitting, the second side surface 12 of the insulating member 10 may protrude slightly from the conductive member 20, and the protruding height is sufficient to achieve snap-fitting of the insulating member 10 and the conductive member 20.

[0047] The insulating sheet 30 is connected to the second side surface 12 of the insulating member 10, and a groove can be provided on the second side surface 12 of the insulating member 10, and the insulating sheet 30 is inserted into the groove. The insulating sheet 30 can be provided on the second side surface 12 of the insulating member 10 to isolate the adjacent conductive members 20. It can be understood that the insulating sheet 30 is made of insulating material, and for example, it can be made of rubber, etc. The insulating sheet 30 is low in cost and light in weight.

[0048] In one embodiment, each copper busbar is provided with a first through hole and a second through hole at both ends thereof, the first through hole being connected to the output end of the power distribution unit of the charging device through screws; and the second through hole being connected to the charging interface through screws.

[0049] The copper bus is connected to the output end of the power distribution unit of the charging device and the charging interface respectively by means of the through hole including the first through hole and the second through hole cooperating with the screw. The connection method is simple and easy to implement and maintain.

[0050] In one embodiment, the lengths of the portions of two adjacent conductive elements 20 located between the second side surfaces 12 of the insulating element 10 are unequal.

[0051] Specifically, the conductive members 20 located between the adjacent second side faces 12 of the insulating member 10 are set to different lengths, and the difference between the lengths can be set according to safety specifications, etc. This setting is to avoid the connection between adjacent charging ports and the conductive members 20 from having electrical influence on each other, which may cause dangers such as short circuits and cross-currents.

[0052] In one embodiment, a connector 40 is provided on a side of the insulating member 10 away from the conductive member 20 , and the connector 40 is used to connect the power output terminal and the power distribution unit of the charging device.

[0053] This method of arranging the connector to connect the power output terminal and the charging device power distribution unit can make the entire system more compact, easier to install and debug, and can also provide additional structural support and connection stability.

[0054] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
