[0048] Please refer to Figure 1 and Figure 2, which is a preferred embodiment of the utility model, the plug-in terminal 10 includes: a shell 100, including a parallel connection surface 130, a non-parallel connection surface 150 and an end surface 140, and the end surface 140 is provided with a first wiring hole 110 and a second wiring hole 120 arranged opposite to each other; a conductor assembly 200, which is installed in the shell 100 and extends along the length direction of the parallel connection surface 130, one end of which is arranged at the first wiring hole 110, and the other end is arranged at the second wiring hole 120; a limit buckle 300, which is arranged on the non-parallel connection surface 150; a handle 400 is inserted into the end surface 140, and the end is connected to the limit buckle 300, and is arranged to rotate the limit buckle 300 when the handle 400 is pushed or pulled.

[0049] The plug-in terminal 10 of the utility model allows the conductor assembly 200 and the limit buckle 300 to be installed in the housing 100, and the limit buckle 300 is controlled by the handle 400 to be detachably fixed to the power supply housing 600 of the power supply system. This design not only simplifies the configuration process of the power supply system, allowing the user to easily configure the AC input, DC input and output, but also significantly reduces the difficulty of the power supply system during expansion, extension and maintenance. In addition, compared with traditional terminals, the utility model effectively solves the difficulties faced in later maintenance, expansion and extension, and provides users with a more efficient and reliable solution. The following is a further detailed introduction to each of the above components.

[0050] like Figure 1 and Figure 2 As shown, the housing 100 is in the shape of a rectangular box as a whole, and includes two oppositely disposed parallel connection surfaces 130, two oppositely disposed end surfaces 140, and two oppositely disposed non-parallel connection surfaces 150. Preferably, the two parallel connection surfaces 130 are disposed parallel to each other, so that when a plurality of the plug-in terminals 10 are connected in parallel according to actual needs, they can be attached to each other to form a whole. Figure 3 , Figure 6 and Figure 7 As shown, a plug-in terminal assembly 20 is formed. In one embodiment of the present application, the non-parallel connection surface 150, the end surface 140, and the machine connection surface 130 are arranged perpendicular to each other. The end surface 140 is provided with a first wiring hole 110 and a second wiring hole 120 which are arranged opposite to each other. The first wiring hole 110 is adapted to the shape and size of the cable, and is used to allow the cable to pass through the housing 100 and be connected to the conductor assembly 200. The second wiring hole 120 is adapted to the shape and size of the bus 620 of the power system, and is used to connect the bus 620 to the conductor assembly 200. As Figure 1 and Figure 3As shown, the plug-in terminal 10 further includes a rotating shaft 310 and a handle 400, and there is a linkage relationship between the handle 400 and the limit buckle 300. The rotating shaft 310 is fixedly mounted on the housing 100. The handle 400 is inserted into the end surface 140, and the end is connected to the limit buckle 300, and is configured to make the limit buckle 300 rotate around the rotating shaft 310 when the handle 400 is pushed or pulled. Specifically, when the plug-in terminal 10 is inserted into the power supply shell 600 of the power supply system, the limit buckle 300 rotates downward around the rotating shaft 310 and is engaged in the slot 610 of the power supply shell 600 to play a limiting role, thereby preventing the plug-in terminal 10 from falling out of the power supply system; when the plug-in terminal needs to be removed from the power supply system, the handle 400 is pulled, and the limit buckle 300 rotates upward around the rotating shaft 310 to disengage from the slot 610 of the power supply shell 600, thereby ensuring that the plug-in terminal 10 can be smoothly removed from the power supply system.

[0051] like Figure 4 and Figure 5 As shown, the conductor assembly 200 includes a conductor 210, a cable terminal 220 and a busbar connection terminal 230. The two ends of the conductor 210 are respectively connected to the cable terminal 220 and the busbar connection terminal 230. The connection methods of the conductor 210 with the cable terminal 220 and the busbar connection terminal 230 include but are not limited to welding, fastening connection and the like. The cable terminal 220 is arranged at the first wiring hole 110 for customer load cable access. The busbar connection terminal 230 is arranged at the second wiring hole 120 for plug-in connection with the busbar 620 of the power supply system. The conductor 210 is generally in the shape of a long strip and is made of a rigid conductive material or a soft conductive material.

[0052] When the capacity of a single plug-in terminal 10 is insufficient, such as Figure 3 , Figure 6 and Figure 7 As shown, two or more plug-in terminals 10 can be connected through a parallel connection assembly 500 to form a larger capacity plug-in terminal assembly 20. The plug-in terminal assembly 20 includes a plurality of the above-mentioned plug-in terminals 10 and a parallel connection assembly 500. The plurality of the plug-in terminals 10 are arranged in parallel, and the parallel connection assembly 500 is used to connect the plurality of the plug-in terminals 10 together in a direction perpendicular to the parallel connection surface 130.

[0053] Specifically, in one embodiment of the present application, the parallel connection assembly 500 includes a parallel connection rod 510 and a mounting hole 520. The mounting hole 520 is provided on the parallel connection surface 130 and penetrates the plurality of plug-in terminals 10. The parallel connection rod 510 is detachably inserted into the mounting hole 520. In another embodiment of the present application, the parallel connection assembly 500 includes a handle connector 530, and the handle connector 530 is detachably covered on the handles 400 of the plurality of plug-in terminals. In other embodiments of the present application, the parallel connection assembly 500 includes the parallel connection rod 510, the mounting hole 520 and the handle connector 530 at the same time.

[0054] When the capacity of a single plug-in terminal 10 is insufficient, a parallel connection assembly 500 can be used to connect two or more plug-in terminals 10 through a parallel connection rod 510 and an installation hole 520, and the handles 400 of two or more plug-in terminals 10 can be connected through a handle connector 530 to form a larger capacity plug-in terminal assembly 20 to meet different capacity requirements.

[0055] The present application also discloses a power supply system, such as Figure 3 and Figure 8 As shown, it comprises: a power housing 600, a busbar 620, and the above-mentioned plug-in terminal 10 or the above-mentioned plug-in terminal assembly 20. Specifically, the power housing 600 is provided with a card slot 610 for cooperating with the limit buckle 300.

[0056] The power housing 600 is provided with a busbar 620, the above-mentioned plug-in terminal 10 or the above-mentioned plug-in terminal assembly 20. The above-mentioned plug-in terminal 10 or the above-mentioned plug-in terminal assembly 20 is matched with the card slot 610 through the limiting buckle 300 and is detachably installed in the power housing 600. The busbar 620 is arranged in the power housing 600 and is detachably connected with the conductor assembly 200.

[0057] The plug-in terminal 10 and the plug-in terminal assembly 20 of the utility model are applicable to both the DC side and the AC side. In actual design, the plug-in terminal 10 can be applicable to different power supply systems by adjusting the size of the housing 100 and the conductor 210 .

[0058] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
