[0039] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0040] The embodiment of the present application discloses a terminal chassis that is easy to assemble.

[0041] Reference Figure 1 A terminal box that is easy to assemble includes a box body 1. The box body 1 is used to install various types of power distribution terminals. The bottom of the box body 1 is provided with a mounting hole 17. In the embodiment of the present application, six mounting holes 17 are provided. The size of the mounting holes 17 can be set differently according to the needs. The mounting hole 17 is used to install an aviation socket, so that the power distribution terminal in the box body 1 is electrically connected to the external power distribution equipment through the aviation socket.

[0042] The side of the box body 1 is provided with a side opening, and a rotating door 2 is rotatably connected to one side of the side opening, and the rotating axis direction of the rotating door 2 is arranged along the vertical direction. When the power distribution terminal assembly work needs to be performed, the operator opens the rotating door 2 to facilitate the installation of the power distribution terminal into the box body 1 from the side opening position.

[0043] The top of the box body 1 is provided with an upper opening, and the upper opening is movably connected with a top cover 3, and the bottom end of the top cover 3 is clamped on the upper opening. When the power distribution terminal needs to be assembled, the operator moves up, lifts and opens the top cover 3, so as to facilitate the installation of the power distribution terminal into the box body 1 from the upper opening.

[0044] A battery module 18, a power module 19 and a circuit board 20 are installed in the box body 1. The battery module 18 is located on one side of the bottom end of the box body 1. The battery module 18 is arranged to avoid the mounting hole 17. The circuit board 20 is located at the upper end of the inner wall of the box body 1 opposite to the side opening. The power module 19 is located in the upper middle part of the inner wall of the box body 1 away from the battery module 18.

[0045] Reference Figure 2 and Figure 3 The box body 1 is provided with a first fixing frame 4, which is used to limit the position of the battery module 18. The first fixing frame 4 is in a "cross" shape, and two adjacent outer ends of the first fixing frame 4 are fixed with a downwardly set limit plate 5, and the other two outer ends of the first fixing frame 4 are fixed with an upwardly set connecting plate 6. The first fixing frame 4 is respectively connected to two inner walls of the box body 1 that are perpendicular to each other through two connecting plates 6. In the embodiment of the present application, the connecting plate 6 is stably connected to the side wall of the box body 1 through a first butterfly screw 21.

[0046] The operator places the battery module 18 to be installed inside the box 1, and then places the first fixing frame 4 above the battery module 18, and connects the two connecting plates 6 to the two inner walls of the box 1 that are perpendicular to each other, so that the first fixing frame 4 is stably installed inside the box 1. At this time, the two limiting plates 5 are respectively abutted against the two side walls of the battery module 18 that are perpendicular to each other, and the other two side walls of the battery module 18 are abutted against the inner wall of the box 1. The limiting plates 5 cooperate with the inner wall of the box 1 to limit the battery module 18 to a corner inside the box 1, thereby making the position of the battery module 18 inside the box 1 relatively stable and not prone to displacement or shaking during handling and transportation.

[0047] Reference Figure 4-Figure 8A fixing bracket 7 is fixedly arranged at the top of the inner side wall of the box body 1, and the fixing bracket 7 is located above the first fixing bracket 4. In the embodiment of the present application, two fixing brackets 7 are provided, and the fixing bracket 7 is located at the top of the circuit board 20. A mounting groove 8 is opened at the bottom of the fixing bracket 7 in the vertical direction. The top of the circuit board 20 is slidably connected to the mounting groove 8, and the bottom of the circuit board 20 is connected to the side wall of the box body 1 through two connecting bolts 9. Two connecting seats 10 arranged in the horizontal direction are fixedly arranged in the box body 1, and the connecting seats 10 are threadedly connected to the connecting bolts 9.

[0048] When installing the circuit board 20, the operator slides the top of the circuit board 20 into the installation groove 8, and the fixing bracket 7 is hook-shaped to limit the top of the circuit board 20. Then, the connecting bolt 9 is passed through the circuit board 20, and the connecting bolt 9 is threadedly connected with the connecting seat 10 until the circuit board 20 is clamped between the top of the connecting seat 10 and the head of the connecting bolt 9. The installation groove 8, the connecting seat 10 and the connecting bolt 9 cooperate to firmly install the circuit board 20 on the inner wall of the box body 1.

[0049] The opening position of the mounting groove 8 is in a "V" shape, and a groove connected to the mounting groove 8 is provided on the fixing bracket 7. The groove is located on one side of the lower end of the mounting groove 8, and the cross section of the groove is in an arc shape. When the circuit board 20 is slidably connected with the mounting groove 8, the "V"-shaped opening of the mounting groove 8 enables the top of the circuit board 20 to slide more smoothly into the mounting groove 8. Since a large number of pins are provided on the circuit board 20, the groove is conducive to reducing the contact area between the circuit board 20 and the fixing bracket 7, which can reduce the situation where the circuit board 20 accidentally touches the conductor and short-circuits and burns.

[0050] A support plate 11 is fixedly arranged on the connection plate 6 located directly below the circuit board 20. The support plate 11 is arranged in the horizontal direction and abuts against the bottom end of the circuit board 20. When the circuit board 20 is installed, the support plate 11 is located below the circuit board 20 to support the circuit board 20, so that the relative position relationship between the circuit board 20 and the box body 1 is more stable.

[0051] The inner wall of the box body 1 is installed with a fixing seat 12 and a second fixing frame 13, and the fixing seat 12 and the second fixing frame 13 are used to install the power module 19. The fixing seat 12 includes a mounting plate 121 and a positioning plate 122, and the mounting plate 121 and the positioning plate 122 are perpendicular to each other. The mounting plate 121 is detachably connected to the inner wall of the box body 1 through two second butterfly screws 22, and the positioning plate 122 is connected to the outer wall of the power module 19. The upper and lower ends of the mounting plate 121 are fixed with a clamping plate 123;

[0052] The second fixing frame 13 includes an adjusting plate 131 and a limiting plate 132. The adjusting plate 131 and the limiting plate 132 are perpendicular to each other. The adjusting plate 131 is connected to the positioning plate 122 through a third butterfly screw 23. The limiting plate 132 is located on the side of the power module 19 away from the mounting plate 121. A plurality of threaded holes 24 are provided on the limiting plate 132. The threaded holes 24 are arranged along the length direction of the limiting plate 132. A handle screw 25 is passed through the threaded hole 24. The handle screw 25 is perpendicular to the limiting plate 132 and is threadedly connected to the threaded hole 24. One end of the handle screw 25 abuts against the side wall of the power module 19.

[0053] The operator installs the mounting plate 121 on the inner wall of the box body 1 through the second butterfly screw 22, and then installs the power module 19 to the inner side of the positioning plate 122. At this time, the clamping plate 123 located below abuts against the bottom end of the power module 19 to support the power module 19, and then the adjustment plate 131 is connected to the positioning plate 122 through the third butterfly screw 23, so that the limiting plate 132 and the power module 19 are away from one side of the mounting plate 121. Finally, the threaded hole 24 at a suitable position is selected, and the handle screw 25 is rotated and inserted into the threaded hole 24, so that the handle screw 25 abuts against the side wall of the power module 19, thereby realizing the installation and limiting operation of the power module 19.

[0054] The card plate 123 is provided with a plurality of card slots 26, the depth direction of the card slots 26 is perpendicular to the mounting plate 121, the card slots 26 are arranged in pairs, and the outer edge of the power module 19 is carded with the card slots 26 along the depth direction of the card slots 26. The card slots 26 can limit the power module 19 in the horizontal direction, so that the relative position of the power module 19 and the box body 1 is relatively stable, and multiple groups of card slots 26 can be suitable for power modules 19 of different specifications.

[0055] The adjusting plate 131 is provided with a long slot hole 14 arranged in the horizontal direction, the outer wall of the positioning plate 122 is fixed with an adjusting seat 15 arranged in the horizontal direction, the adjusting seat 15 passes through the long slot hole 14, and the outer side of the adjusting plate 131 is provided with a third butterfly screw 23 threadedly connected to the adjusting seat 15.

[0056] The operator moves the adjustment plate 131 along the length direction of the long slot hole 14, thereby changing the relative position between the fixing seat 12 and the second fixing frame 13. By adjusting the distance between the mounting plate 121 and the limiting plate 132, the connection relationship between the fixing seat 12 and the second fixing frame 13 can be adaptively adjusted according to the size of the power module 19.

[0057] The implementation principle of a terminal chassis that is easy to assemble in an embodiment of the present application is: first install the circuit board 20: first clamp the top of the circuit board 20 in the installation groove 8, and then pass the connecting bolt 9 through the circuit board 20, so that the connecting bolt 9 is threadedly connected with the connecting seat 10, so that the circuit board 20 is installed on the inner wall of the chassis.

[0058] Then install the battery module 18: place the battery module 18 inside the box 1, and then place the first fixing frame 4 above the battery module 18, and connect the two connecting plates 6 to the two inner walls of the box 1 that are perpendicular to each other, so that the first fixing frame 4 is stably installed inside the box 1. At this time, the two limiting plates 5 are respectively abutted against the two side walls of the battery module 18 that are perpendicular to each other, and the other two side walls of the battery module 18 are abutted against the inner wall of the box 1. The limiting plates 5 cooperate with the inner wall of the box 1 to limit the battery module 18 to a corner inside the box 1.

[0059] Finally, install the power module 19: install the mounting plate 121 on the inner wall of the box body 1 through the second butterfly screw 22, and then install the power module 19 to the inner side of the positioning plate 122. At this time, the clamping plate 123 located below abuts against the bottom end of the power module 19 to support the power module 19, and then connect the adjustment plate 131 with the positioning plate 122 through the third butterfly screw 23, so that the limiting plate 132 and the power module 19 are away from one side of the mounting plate 121, and finally rotate the handle screw 25 to make the handle screw 25 abut against the side wall of the power module 19 to realize the installation and limiting operation of the power module 19.
