[0031] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a power distribution device for a split-type DC charging pile host, comprising a mounting frame 1, the mounting frame 1 consisting of four support rods 11 and two upper and lower supporting plates 12, the four support rods 11 being respectively mounted on the four corners of the two supporting plates 12, the mounting frame 1 being mounted inside the host of the split-type DC charging pile, the upper ends of the two supporting plates 12 being fixedly mounted with a PDU module 4, the PDU module 4 being the prior art (PDU is the abbreviation of Power Distribution Unit, referring to the power distribution unit), the PDU module 4 mainly plays the role of power distribution, circuit protection, signal transmission and control, etc., the PDU module 4 inputs AC power, and outputs DC power after passing through the internal rectification and conversion circuit.

[0032] The front ends of the two PDU modules 4 are each provided with a connecting mechanism 5, which is used to connect the PDU module 4 with the charging module and gun line of the charging pile. The front ends of the two support rods 11 located on the front side are fixedly connected to two mounting rods 21 arranged up and down, and the front ends of the four mounting rods 21 are fixedly connected to an insulating plate 2. A connecting rod 22 is fixedly installed between the two mounting rods 21 located on the same side on the upper and lower sides. The insulating plate 2 can prevent the operator from accidentally touching the wiring parts and causing electric shock accidents.

[0033] Furthermore, an air switch mounting plate 3 is fixedly installed on the lower rear end of the two support rods 11 at the rear side. The air switch mounting plate 3 is used to install an air switch, which can turn off or on the overall equipment power supply of the split DC charging pile host.

[0034] Specifically, such as Figure 6 As shown, the rear end of the PDU module 4 is fixedly connected to two handles 41 arranged on the left and right, which is convenient for users to install or remove the PDU module 4. Multiple DC contactors are installed inside the PDU module 4. The DC contactor is a prior art. The DC contactor refers to a contactor used in a DC circuit, which is mainly used to control the DC circuit main circuit, control circuit and excitation circuit, etc. The front end of the PDU module 4 is provided with multiple contact copper bars 42, and the multiple contact copper bars 42 are respectively connected to multiple DC contactors. The PDU module 4 is a prior art, and its rear end has a power supply interface to provide power.

[0035] In order to ensure the safety of the lines and the convenience of installation in a compact space, Figure 7 and Figure 8 As shown, the connecting mechanism 5 includes a rectangular frame 51, the rear end of the rectangular frame 51 is fixedly connected to the two support rods 11 located on the front side, and the front ends of the two horizontal parts of the rectangular frame 51 are fixedly connected to multiple insulating columns 52 corresponding to the contact copper bars 42. The insulating columns 52 are made of insulating material, and the front ends of every two insulating columns 52 corresponding to the same column are commonly provided with a copper bus 53, which is used to install the connected lines and cables.

[0036] Specifically, such as Figure 8 and Figure 9 As shown, the copper busbar 53 includes a C-shaped piece 531, the front portion of the upper end of the C-shaped piece 531 is fixedly connected to a first mounting piece 532, the front portion of the lower end of the C-shaped piece 531 is fixedly connected to a second mounting piece 533, and the length of the first mounting piece 532 is greater than the length of the second mounting piece 533. The rear ends of the first mounting piece 532 and the second mounting piece 533 are both connected to the corresponding insulating column 52, and the rear end of the C-shaped piece 531 is fixedly connected to the corresponding contact copper bar 42.

[0037] It should be noted that the C-shaped piece 531 , the first mounting piece 532 , and the second mounting piece 533 are formed by bending the copper bar into a continuous right angle, so the C-shaped piece 531 , the first mounting piece 532 , and the second mounting piece 533 are integrated.

[0038] Furthermore, an L-shaped mounting piece 54 is fixed to the first mounting piece 532 or the front end of the first mounting piece 532 in each copper busbar 53. The L-shaped mounting piece 54 is made of copper and consists of a horizontal portion and a vertical portion. A cable terminal 56 is provided on the outer surface of the vertical portion of the L-shaped mounting piece 54 close to the horizontal portion of the L-shaped mounting piece 54. The cable terminal 56 is used to install the cable of the charging gun. In addition, the L-shaped mounting pieces 54 installed at the front ends of the two adjacent copper buses 53 are in opposite positions up and down, and the vertical portions of the L-shaped mounting pieces 54 installed at the front ends of the two adjacent copper buses 53 are in opposite positions left and right, that is, Figure 8 As shown, the installation positions of the L-shaped mounting pieces 54 in the same row are staggered up and down, and the installation of the cable terminals 56 on the surface of the L-shaped mounting pieces 54 is staggered left and right, so that the cables installed in each cable terminal 56 in the two connecting mechanisms 5 can be arranged staggered.

[0039] Further, such as Figure 10 As shown, the front-to-back length of the vertical portion of the L-shaped mounting piece 54 in the upper connecting mechanism 5 is greater than the front-to-back length of the vertical portion of the L-shaped mounting piece 54 in the lower connecting mechanism 5, so the front-to-back positions of the cables connected from the upper connecting mechanism 5 and the cables connected from the lower connecting mechanism 5 are staggered, which can facilitate wiring arrangement after installation.

[0040] In addition, a plurality of output line terminals 55 are provided at the upper front end of the first mounting piece 532 . The output line terminals 55 are used to install output lines for connecting with each charging module to output electricity to each charging module.

[0041] Furthermore, both connecting rods 22 pass through the openings of the corresponding C-shaped pieces 531, and the outer surface profile of the connecting rods 22 matches the profile of the openings of the C-shaped pieces 531. The connecting rods 22 are made of an insulating material to prevent the copper bars 53 from being connected. After the connection mechanism 5 and the various circuits are installed, the connecting rods 22 are used to hold the copper bars 53 in place to prevent deformation of the copper bars 53 over time.

[0043] The working principle of the present invention is as follows: when installing the power distribution device, the PDU module 4 is installed on the upper end of the mounting frame 1, and then the circuit breaker mounting plate 3 is installed, and then the rectangular frame 51 is installed. The multiple contact copper bars 42 will pass through the corresponding rectangular frame 51, and then the insulating column 52 is installed. Then, the copper bus 53 is installed with the corresponding contact copper bars 42 and the insulating column 52 by bolts. Do not tighten the bolts at this time, and then install the L-shaped mounting piece 54, install the mounting rods 21 on both sides, and insert the connecting rod 22 into the openings of the multiple C-shaped pieces 531 to determine the position of the copper bus 53, and then tighten the bolts to fix the copper bus 53, and then install the output line terminal 55 and cable terminal 56 that have been connected, organize the lines, and finally install the insulating plate 2;

[0044] During operation, after the power is input into the PDU module 4, it will be transmitted by the contact copper bar 42 to the charging module connected to the output line terminal 55 and the gun line cable connected to the cable terminal 56, thereby regulating the output power of each charging pile terminal. The arrangement of the copper bus 53, L-shaped mounting plate 54, and cable terminal 56 can ensure that the positions of each cable are arranged neatly, ensuring the safety between lines and the convenience of installation in a compact space.
