[0002] The distribution cabinet (box) is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the distribution system. The distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits. Usually, the distribution cabinet introduces the bus and distributes it to various electrical equipment through various branches such as circuit breakers. Usually, the most common things in the distribution cabinet are lines and circuit breakers. In order to ensure maintenance and other uses, it is necessary to ensure that the internal lines of the distribution cabinet are neat, so wiring is required, but there are still the following disadvantages in the actual wiring operation:

[0003] Currently, only a single bracket is used to install the circuit breaker in the wiring inside the power distribution cabinet, and the remaining lines are completely arranged by manual bending, etc. There is no auxiliary wiring component. Manual wiring alone will still cause errors, which is inconvenient for subsequent maintenance. Moreover, after long-term use, the wiring position may change, and the corresponding position of the line cannot be accurately observed during maintenance;

[0004] Secondly, after the lines are distributed, they are mostly connected to various devices such as circuit breakers. However, the circuit breakers and other devices are installed in a certain position before wiring. However, the wiring positions of devices such as circuit breakers are above and below them, which is not very convenient when connecting the lines, especially the lines below, which require workers to look up to install them.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1-8As shown, the utility model is an internal wiring assembly of a power distribution cabinet, comprising a mounting panel 1, a bottom plate 2, two triangular plates 3, a mounting convex strip 4 and a circuit breaker 5. The bottom plate 2 is fixed at the lower edge of one side of the mounting panel 1, and the triangular plates 3 are fixed between the two upper short sides of the bottom plate 2 and the side of the mounting panel 1. Two symmetrically distributed mounting ear plates 102 are fixed to the upper part of the mounting panel 1 away from the bottom plate 2, and the mounting convex strip 4 is rotatably connected between the two mounting ear plates 102;

[0031] The two ends of the bottom plate 2 and the mounting panel 1 are fixed to the two opposite inner walls of the distribution cabinet. They can be fixed by welding, or the triangle plate 3 can be fixed to the inner wall of the distribution cabinet by bolts or other fasteners. The selection is based on actual needs. Subsequently, the mounting panel 1 is rotatably connected to the mounting convex strip 4 through the mounting ear plate 102, so that the mounting convex strip 4 can rotate, thereby driving the circuit breaker 5 to rotate.

[0032] A wire slot 101 is provided in the installation panel 1 below the installation convex strip 4; three wire slots 201 are provided in the bottom plate 2 at equal intervals; a circuit breaker 5 is provided in the installation convex strip 4;

[0033] The wires passing through the bottom plate 2 are passed through the wire clamping groove 101 to the front side of the installation panel 1 so as to be electrically connected to the circuit breaker 5 installed on the installation convex strip 4 .

[0034] The height of the bottom plate 2 and the threading groove 201 is lower than the height of the wire clamping groove 101 , so that the wire can be easily threaded out of the threading groove 201 in the bottom plate 2 and then enter the bottom of the circuit breaker 5 through the wire clamping groove 101 .

[0035] The raised portion of the mounting convex strip 4 is located at a side away from the mounting panel 1, and a through slot 402 is formed in both the mounting convex strip 4 and the raised portion thereof. A pin 403 is fixed at both ends of the mounting convex strip 4, and the end of the pin 403 away from the mounting convex strip 4 penetrates the mounting ear plate 102 and is rotatably connected thereto.

[0036] The design of the mounting convex strip 4 with its raised portion just fits the structure of the circuit breaker 5. A through slot 402 is arranged inside the mounting convex strip 4, which is convenient for reducing weight and has a certain heat dissipation space. Next, the mounting pin 403 at the end of the mounting convex strip 4 is rotatably connected to the mounting ear plate 102. The mounting convex strip 4 is rotated so that the circuit breaker 5 on the mounting convex strip 4 is horizontally placed, and the wiring holes at the bottom thereof are horizontally exposed (such as Figure 4 As shown in the figure, the worker can perform the wiring operation without bending over and looking up. After wiring the bottom of the circuit breaker 5, the worker returns to the original position and performs wiring on the upper part of the circuit breaker 5.

[0037] The length of the mounting convex strip 4 is equal to the distance between the two mounting ear plates 102. The mounting convex strip 4 above and below the through slot 402 is provided with equidistantly distributed screw holes 401. The circuit breaker 5 is screwed into the mounting convex strip 4 and then screwed into the screw holes 401 to be fixedly connected to the mounting convex strip 4.

[0038] The circuit breaker 5 is similar to a conventional structure and is fixed to the mounting convex strip 4 by fasteners such as screws.

[0039] The length of the installation convex strip 4 is smaller than the length of the wire clamping groove 101, the wire threading groove 201, the bottom plate 2 and the installation panel 1. The length of the bottom plate 2 and the installation panel 1 is equal, and the length of the wire clamping groove 101 and the wire threading groove 201 is equal.

[0040] Each triangular plate 3 is provided with two through-going mounting holes 301, the cross sections of the mounting panel 1 and the bottom plate 2 are distributed at right angles, and the two right-angled surfaces of the triangular plate 3 are respectively welded and fixed to the mounting panel 1 and the bottom plate 2;

[0041] The triangular plate 3 is fixed to the inner wall of the power distribution cabinet by fasteners such as bolts passing through the mounting hole 301 .

[0042] The specific working principle of the utility model is as follows: first, the two ends of the bottom plate 2 and the mounting panel 1 are fixed on the two opposite inner walls in the power distribution cabinet, and the triangular plate 3 can also be fixed to the inner wall of the power distribution cabinet through the mounting hole 301 by fasteners such as bolts. Then, the circuit breaker 5 is similar to the conventional structure, and the mounting convex strip 4 cooperates with the design of its convex part, which just fits the structure of the circuit breaker 5. The circuit breaker 5 is fixed to the mounting convex strip 4 by fasteners such as screws. Then, the branch line in the bus is taken out, passed through a wire threading groove 201 in the bottom plate 2, and then simply bent and passed through the wire clamping groove 101 until it passes out to the front side of the mounting panel 1. Because the mounting pin 403 at the end of the mounting convex strip 4 is rotatably connected with the mounting ear plate 102, the mounting convex strip 4 is rotated to make the circuit breaker 5 on the mounting convex strip 4 horizontal, and the wiring holes at its bottom are horizontally exposed (such as Figure 4 As shown), after wiring the bottom of the circuit breaker 5, it is restored to its original position and wiring is performed on the upper part of the circuit breaker 5. The wiring assembly located on the upper layer can take another set of branch lines through the second threading groove 201 and connect to the circuit breaker 5 on the wiring assembly. Each set of branch lines corresponds to a threading groove 201 and is connected to the circuit breaker 5 on the wiring assembly (as shown Figure 8 As shown), the whole is neat and orderly.
