Each fixing plate 81 is provided with a fixing structure to fix the fixing plate 81 on the adjusting rail 3. Two left-right symmetrical support frames 8 are connected to the front side of the fixing plate 81. Three conductive rails 9 are evenly spaced apart and connected between the two support frames 8. A connecting busbar 11 is connected between the right sides of the three conductive rails 9 on the upper and lower sides. Four shunt copper bars 10 are slidably connected to each conductive rail 9. The bottom of the shunt copper bar 10 can be connected to the terminal 6 at the top of the sub-circuit breaker 5. The three upper conductive rails 9 are connected with a mother copper bar 7, which can be inserted into the terminal 6 at the bottom of the main circuit breaker 5 by moving upward.

[0031] like Figure 3 and Figure 4 As shown, the locking structure includes a mounting seat 51 and a locking frame 52. The mounting seat 51 is provided at the rear side of the circuit breaker 5, and the locking frame 52 is plugged onto the mounting seat 51. The locking frame 52 is removed, and the rear side of the mounting seat 51 of the circuit breaker 5 is sleeved on the mounting plate 4. Then, the locking frame 52 is passed through the mounting seat 51 to complete the assembly. The circuit breaker 5 and the locking frame 52 are respectively located at the front and rear sides of the mounting plate 4, so that the circuit breaker 5 can be installed on the mounting plate 4.

[0032] like Figure 4 and Figure 5 As shown, the mounting structure includes a sliding plate 41, a latch 42 and an elastic member 43. A plurality of groups of jacks are evenly spaced from top to bottom on the two adjustment rails 3, and each group of jacks is provided with two. The rear side of the mounting plate 4 is slidably connected with a sliding plate 41. The left and right sides of the sliding plate 41 are connected with two latches 42.

[0033] like Figure 4 and Figure 7 As shown, the fixing structure includes a sliding plate 82, a latch 83 and an elastic member 84. The sliding plate 82 is slidably connected to the fixing plate 81. Two elastic members 84 are connected between the sliding plate 82 and the fixing plate 81. The elastic member 84 is a return spring. Two latches 83 are connected to the left and right sides of the sliding plate 82. The latches 83 can be plugged into the socket of the adjustment track 3 to fix the fixing plate 81 on the adjustment track 3.

[0034] When using the power distribution cabinet, first install the circuit breaker 5 on the mounting plate 4. During the installation process, the main circuit breaker 5 is installed in the middle of the uppermost mounting plate 4, and the remaining sub-circuit breakers 5 are evenly spaced and installed on the two mounting plates 4 below. Then, pull the second sliding plate 82 to disengage the second plug 83 from the socket of the adjustment track 3, and the second elastic member 84 is stretched, and then pull the two fixed plates 81 to slide upward, so that the three upper mother copper bars 7 are respectively inserted into the three terminal posts 6 at the bottom of the main circuit breaker 5. After insertion, release the second sliding plate 82, and under the action of the second elastic member 84, the second sliding plate 82 and the second plug 83 are reset and inserted into the socket of the adjustment track 3, and the second sliding plate 82 is fixed. Finally, the sliding plate 41 on the two lower mounting plates 4 can be slid so that the pin 42 is disengaged from the adjusting track 3, and the elastic member 43 is stretched. Then, the two lower mounting plates 4 are pulled upward, thereby driving the circuit breaker 5 to move upward until the terminal 6 above the circuit breaker 5 is connected to the bottom of the shunt copper bar 10, and then the sliding plate 41 is released. At this time, under the action of the elastic member 43, the sliding plate 41 is reset to drive the pin 42 to be inserted into the jack of the adjusting track 3, thereby fixing the two lower mounting plates 4. In this way, the power distribution cabinet can be used, and the connection work between the various terminal posts 6 can be more convenient during use, which is more convenient to operate.

[0035] like Figure 6 and Figure 8 As shown, it also includes a power connection mechanism, which includes a guide rod 121, a mounting frame 122, an elastic member 123 and a distribution copper bar 124.

An elastic member 123 is connected between the mounting frame 122 and the mounting plate 4. The elastic member 123 is a tension spring and is sleeved on the guide rod 121, so that the elastic member 123 is guided by the guide rod 121. Four groups of distribution copper bars 124 are evenly installed on the mounting frame 122, and each group of distribution copper bars 124 is provided with three. The distribution copper bars 124 can be moved up and plugged into the position of the terminal 6 at the bottom of the circuit breaker 5 to achieve circuit connection.

[0036] The surfaces of the non-connected parts of the main copper bar 7 , the shunt copper bar 10 , the connecting busbar 11 and the distribution copper bar 124 are all provided with insulating sleeves.

[0037] When using the power distribution cabinet, the wires of external electrical equipment can be connected to the distribution copper bar 124, and power can be supplied through the distribution copper bar 124. When the circuit breaker 5 is damaged and needs to be repaired, the mounting frame 122 can be directly pulled downward to drive the distribution copper bar 124 to move downward and separate from the terminal 6 at the bottom of the circuit breaker 5. The elastic member 3 123 is stretched, and the circuit breaker 5 can be removed for maintenance, which is more convenient during maintenance.

[0038] like Fig. 9 and Fig.10 As shown, a tensioning mechanism is also included, which includes a connecting sleeve 131, an extrusion block 132, a four elastic member 133 and a connecting column 134. The lower part of each shunt copper bar 10 and the upper part of the distribution copper bar 124 are sleeved with a connecting sleeve 131, and the connecting sleeve 131 is made of insulating material. Three connecting columns 134 are evenly spaced and connected to the rear side of the connecting sleeve 131. The extrusion block 132 is slidably connected between the three connecting columns 134. The extrusion block 132 is provided with an inclined surface on the side close to the circuit breaker 5. When the circuit breaker 5 contacts the extrusion block 132, it contacts the inclined surface of the extrusion block 132 and pushes the extrusion block 132 to move. An elastic member four 133 is connected between the extrusion block 132 and the connecting sleeve 131, and the elastic member four 133 is a tensioning spring.

[0039] When the circuit breaker 5 moves so that the upper terminal 6 thereof is connected with the shunt copper bar 10, the circuit breaker 5 will push the extrusion block 132 to move through the inclined surface of the extrusion block 132, so that the elastic member 133 is stretched, and the elastic member 133 will apply a pulling force to the shunt copper bar 10 through the connecting sleeve 131, so that the shunt copper bar 10 is tightly attached to the top of the terminal 6 of the circuit breaker 5, and when the distribution copper bar 124 moves up and connects with the terminal 6 at the bottom of the circuit breaker 5, the extrusion block 132 on the distribution copper bar 124 will also be pushed by the circuit breaker 5, so that the elastic member 133 pulls the distribution copper bar 124 to be tightly attached to the terminal 6 at the bottom of the circuit breaker 5, so that the distribution copper bar 124 and the shunt copper bar 10 can be assisted to be tightly attached to the terminal 6 of the circuit breaker 5, thereby ensuring stability during the connection process.

[0040] like Figure 11-13As shown, it also includes a wire mechanism, which includes a fixed cylinder 141, a connecting wire 142, a rotating cylinder 143, an elastic locking pin 144 and a connecting seat 145.

Each connecting seat 145 is connected to two elastic locking pins 144, and the front side of the elastic locking pins 144 is provided with a chamfer. The connecting seat 145 can fix the fixed cylinder 141 on the adjusting rail 3 by inserting the elastic locking pins 144 into the jack of the adjusting rail 3. When the fixed cylinder 141 needs to be removed, the fixed cylinder 141 can be directly pulled out. The rotating cylinder 143 is connected to the lower part of the front side of the fixed cylinder 141, and a snap-fit ​​structure is provided between the rotating cylinder 143 and the connecting seat 145, so that the rotating cylinder 143 can be rotated to the fixed cylinder. When the rotating cylinder 143 is rotated, the elastic clip will contact with the connecting seat 145 and deform, until the rotating cylinder 143 is rotated to close with the fixed cylinder 141, at which time the elastic clip is reset and snapped into the clip slot to fix the rotating cylinder 143 and the fixed cylinder 141, and the lower front part of the distribution copper bar 124 is connected with a connecting wire 142, which can penetrate into the rotating cylinder 143 and the fixed cylinder 141 and be connected to external electrical equipment, and the connecting wire 142 can be protected by the fixed cylinder 141 and the rotating cylinder 143 to avoid the connecting wire 142 being messy, and the rotating cylinder 143 can be opened to sort out the wires when the wires need to be repaired, so as to facilitate the repair work of the wires.
