Description

Technical Field

[0001] The invention belongs to the technical field of distribution box components, and more specifically, particularly relates to a distribution box. Background Art

[0002] A distribution box is an electrical device that is mainly used to distribute electrical energy and control and protect circuits. It is a closed or semi-closed metal cabinet that centrally installs switchgear, measuring instruments, protective electrical appliances and auxiliary equipment. The electrical rails of the distribution box are rail devices installed in the distribution box for installing various electrical components (such as circuit breakers, contactors, relays, etc.). It provides a standardized installation platform for electrical components, allowing them to be easily installed, disassembled and moved.

[0003] In the design and application of distribution boxes, electrical rails play a vital role. They provide a basis for the installation and positioning of various electrical components. However, the existing electrical rail technology on the market has many limitations.

[0004] Most traditional electrical guide rails adopt a fixed structure. This fixing method makes the position of the guide rail in the distribution box unchanged in most cases. On the one hand, most existing electrical guide rails are directly fixed to the inside of the distribution box by bolts. Although this fixing method can ensure the stability of the guide rail, it greatly limits the mobility of the guide rail. During the installation process, if it is found that the position of the guide rail needs to be fine-tuned to better adapt to the installation of electrical components or meet the rationality requirements of wiring, the guide rail fixed by bolts is difficult to adjust, because removing and reinstalling the bolts is not only time-consuming and labor-intensive, but also may damage the installation holes of the distribution box or the guide rail itself after multiple operations, affecting the overall installation quality and the service life of the distribution box. Therefore, the existing distribution box electrical guide rails have the problem of being difficult to adjust.

[0005] Most of the existing electrical guide rails are of fixed length. In actual applications, the sizes of distribution boxes vary. Different usage scenarios and user needs will lead to differences in the sizes of distribution boxes. Fixed-length electrical guide rails cannot be adjusted according to the actual length of the distribution box. This means that in some non-standard-sized distribution boxes, the guide rails either cannot fully utilize the internal space of the distribution box, resulting in space waste, or are not long enough to meet the installation quantity requirements of electrical components. This inflexibility has brought great inconvenience to the production, installation and use of distribution boxes, limiting the effective application of distribution boxes in different fields and complex environments, resulting in the problem of low applicability of existing distribution boxes.

[0006] Therefore, the existing structure and defects are studied and improved, and a distribution box is provided. Summary of the invention

The gear ring 603 is fixedly mounted on the outer wall of the connecting sleeve 405. The eight micro motors 601 are electrically connected to the control panel 2.

[0048] Working principle:

[0049] In the first step, when the present application needs to be used, the position of the mounting mechanism 4 can be adjusted according to the size of the electrical component 7, mainly adjusting the spacing between the mounting mechanisms 4. The specific operation process is as follows: first observe the mounting frame 401 of the mounting mechanism 4 that needs to be adjusted, and control the micro motor 601 installed on the mounting mechanism 4 to start through the control panel 2. The micro motor 601 drives the active gear 602 to rotate, and the active gear 602 drives the gear ring 603 to rotate. The gear ring 603 drives the connecting sleeve 405 to rotate. The connecting sleeve 405 is arranged based on the bearing 404 so that it can rotate. When the connecting sleeve 405 rotates, its internal thread groove 406 cooperates with the screw rod 109, so that the mounting mechanism 4 as a whole can be translated on the screw rod 109, and the limit block 402 and the T-shaped limit rod 108 are adapted to limit the other end of the mounting mechanism 4 from deviation, thereby achieving the effect of adjusting the spacing between the mounting mechanisms 4.

[0050] In the second step, the number of connecting mechanisms 5 can be adjusted according to the length of the electrical component 7. First, a corresponding number of connecting mechanisms 5 are prepared according to the length of the electrical component 7. Each connecting mechanism 5 is inserted into the placement slot 407 through the space reserved by the fixing rod 408 and the placement slot 407. The T-shaped block 501 is sleeved with the fixing rod 408 through the through hole 502. Each connecting mechanism 5 is fixed by plugging with the plug 505 through the plug hole 504, so that each guide rail module 506 is docked (the adjacent baffle 103 can be removed for installation operation). The electrical component 7 is slidably engaged with the guide rail module 506 and fixed by bolts. The extrusion bolt 8 is screwed into the threaded hole 409 to squeeze the connecting mechanism 5 away from the end of the driving mechanism 6, so that each connecting mechanism 5 is fixed on the mounting frame 401, so as to adapt to electrical components 7 of different lengths.

[0051] In the third step, the present application opens a square groove 106 on the flat plate 105, and fixes and connects the damping slide rails 107 at both ends of the square groove 106, so that the fixed plate 3 is slidably connected to the damping slide rails 107. When wiring, the electrical component 7 of the present application can be connected to the circuit controller in the wiring compartment 110, and pass through each second wiring harness sleeve 303. The wiring harness passing through the second wiring harness sleeve 303 passes through each first wiring harness sleeve 302, and then is connected to each electrical component 7. The tension of the wiring harness can be adjusted by moving the position of the fixed plate 3 in the square groove 106, so that each first wiring harness sleeve 302 can pull the internal wiring harness, so that the wiring harness is tightened to prevent the cable from being loose. If there are many or long cables, the cables can be directly passed through the square groove 106 to connect with each electrical component 7, and the cables can be directly clamped by the fixed plate 3 to straighten the cables below the flat plate 105, and the cables above the flat plate 105 can be hung above the fixed plate 3, which plays an effect of arranging the wiring and preventing the wiring harness from being scattered.
