Description

Technical Field

[0001] The present invention relates to the field of power distribution cabinets, and in particular to a power distribution cabinet which is convenient for line maintenance. Background Art

[0002] In the power distribution system, the distribution cabinet, as a key power control and distribution equipment, undertakes important functions such as receiving, distributing and protecting electric energy. Currently, prefabricated copper busbars and wires are the mainstream method of connecting the lines of the distribution cabinet, and the electrical components are generally installed on a large flat plate. At the same time, in order to improve the aesthetics, wire troughs are used for S-shaped wiring arrangement. This traditional layout takes up a lot of space inside the distribution cabinet, and the overall wiring length is long, which greatly compresses the installation space of electrical components. This not only limits the functional expansion of the distribution cabinet, but also may lead to poor heat dissipation and inconvenient maintenance due to the compact installation of components. It is difficult to meet the growing demand for efficient and compact power distribution.

[0003] Furthermore, the existing large flat panels for mounting electrical components fail to provide a flexible and adjustable mounting structure or positioning mechanism. Therefore, when various electrical components of different sizes and specifications, such as relays, air switches, and contactors, are fixedly mounted on the large flat panel, these electrical components have different sizes, resulting in difficulty in maintaining consistency in the relative positions between each electrical component and the established connection points. There are certain differences, making it difficult for prefabricated copper busbars of uniform specifications to directly adapt to each electrical component and the connection points. Therefore, workers need to perform secondary processing such as cutting and bending on the prefabricated copper busbars, which greatly increases the complexity of the installation process, prolongs the installation working hours, and to a certain extent increases the installation and subsequent maintenance costs. There are obvious limitations in practical applications. Summary of the Invention

[0004] In order to overcome the shortcomings that the installation layout of electrical components and lines inside the existing distribution cabinet causes a large amount of space inside the distribution cabinet to be occupied, the overall wiring length is long, which greatly compresses the installation space of electrical components, and the existing large flat plate for installing electrical components fails to provide a flexible and adjustable installation structure or positioning mechanism, resulting in the inability of prefabricated copper busbars of uniform specifications to directly adapt to various electrical components and connection points, the present invention provides a distribution cabinet that is convenient for line maintenance.

[0005] The technical solution is as follows: A distribution cabinet that is convenient for line maintenance, including a distribution cabinet; also including a mounting plate, a plug-in plate, a mounting block, a mounting bar, a wire comb, a cable clip and a connecting bar; several mounting plates are connected in the distribution cabinet; the front side of the card slot of each mounting plate is slidably connected to several plug-in plates; each plug-in plate is fixedly connected to a mounting block; a mounting bar can be fixedly slidably connected between every two mounting blocks; several connecting bars are connected to the back side of the mounting plate; two cable clips are plugged into the connecting bar; a wire clip groove is provided in the cable clip; several wire combs are connected to the top and bottom of the mounting plate.

[0006] Preferably, an elastic buckle is provided at the end of the connecting strip.

[0007] Preferably, the mounting plate is arc-shaped.

[0008] Preferably, each cable buckle is provided with friction lines.

[0009] Preferably, each wire clamping slot is provided with a plurality of blocking pieces at an angle.

[0010] Preferably, plugs are installed at both ends of the slot.

[0011] Preferably, the mounting strip is made of insulating material.

[0012] Preferably, a shielding plate is further included; a clamping portion is provided on each wire comb; and a shielding plate for shielding cables is clamped between adjacent wire combs of two adjacent mounting plates via the clamping portion.

[0013] Preferably, each wire comb is provided with a sliding portion; and a hook is provided at the lower portion of each wire comb.

[0014] Preferably, a horizontal bracket and a vertical bracket are provided in the distribution cabinet; several horizontal brackets are symmetrically fixed in the distribution cabinet; all horizontal brackets on the same side are fixed to a vertical bracket; all mounting plates are fixed to two vertical brackets through a connecting frame.

[0015] The present invention has the following advantages: through the cable clips and connecting strips, workers can hide the wires behind the mounting plate for cable arrangement. In this way, the wiring of the branch lines is L-shaped instead of the usual S-shaped, which can greatly reduce the wiring length. Different wires are distinguished by cable clips and wire combs according to function, location and other standards, making it easy to find the cables and easing subsequent maintenance. Moreover, the cable clips replace the traditional cable ties to centralize the cables and will not completely tie the cables. If a cable needs to be scrapped and replaced, the cable can be directly removed after removing the connections at both ends of the cable, making replacement convenient.

[0016] The wire combs make it easier for workers to arrange the wires in a regular pattern. Meanwhile, the shielding plates cover the wires on the back of the mounting plates, so the cables crossing the upper and lower mounting plates are blocked by the shielding plates. When all are assembled, only the various electrical components and the cable ends at their ends are visible from the outside. Most of the cables are hidden behind the mounting plates and shielding plates, leaving the interior of the entire distribution cabinet neat and beautiful.

[0017] When using prefabricated copper busbars to connect relays, air switches, contactors and other electrical components of various sizes and specifications in the distribution cabinet, workers can adjust the height of the installation bar so that the upper or lower connection ends of the electrical components of various sizes and specifications are at the same height, which makes it easier to use a unified prefabricated copper busbar to connect and install electrical components of different sizes. This solves the problem of workers having to perform secondary processing such as cutting and bending on the prefabricated copper busbars, making the installation process more convenient and simple, and greatly improving the installation efficiency of the distribution cabinet.

[0018] The present invention also has the following beneficial effects:

[0019] The mounting plate is curved, which is different from the existing straight plate installation. After the electrical components are installed, there will be a gap between the back side of the electrical components and the mounting plate to facilitate the heat dissipation of the electrical components;

[0020] The mounting strips are made of insulating material. When a short circuit or leakage occurs in an electrical component on one of the mounting strips, the insulating mounting strip prevents the current from being transmitted to the surrounding electrical components, causing damage to the surrounding electrical components.

DETAILED DESCRIPTION

[0031] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0032] Example 1: A power distribution cabinet 1 that facilitates line maintenance, such as Figures 1-9 As shown, it includes a power distribution cabinet 1;

[0033] It also includes a mounting plate 101, a plug-in plate 102, a mounting block 103, a mounting strip 104, a wire comb 105, a cable clip 107 and a connecting strip 109; a number of mounting plates 101 are connected to the power distribution cabinet 1; a number of plug-in plates 102 are slidably connected to the front side of the card slot 10101 of each mounting plate 101; a mounting block 103 is fixedly connected to each plug-in plate 102; a mounting strip 104 can be fixedly slidably connected between every two mounting blocks 103; a number of connecting strips 109 are slidably connected to the back side of the mounting plate 101; two cable clips 107 are symmetrically plugged into the connecting strip 109; a wire clip groove 10701 is provided in the cable clip 107; a number of wire combs 105 are clamped on the top and bottom of the mounting plate 101, and a number of wire threading grooves 10501 are provided on the wire comb 105.

[0034] An elastic buckle 10902 is provided at the end of the connecting bar 109. When the cable buckle 107 is inserted into the connecting bar 109, the elastic buckle 10902 protrudes from the sliding groove on the lower side of the cable buckle 107, thereby limiting the cable buckle 107 to prevent the cable buckle 107 from falling off. When the worker needs to remove the cable buckle 107, he only needs to press the elastic buckle 10902 to make the elastic buckle 10902 enter the sliding groove on the lower side of the cable buckle 107 and then pull the cable buckle 107 out.

[0035] The mounting plate 101 is arc-shaped.

[0036] Each cable buckle 107 is provided with friction lines 10703. When removing the cable buckle 107, the worker can hold the friction lines 10703, thereby increasing the friction between the worker's palm and the cable buckle 107, making it easier for the worker to pull out the cable buckle 107.

[0037] Two baffles 10702 are obliquely arranged on each wire slot 10701. When workers are organizing the cables, they can squeeze the baffles 10702 and place the cables into the wire slot 10701. After the cables are installed, the two baffles 10702 are reset and pressed against each other to prevent the cables from falling out of the wire slot 10701.

[0038] Plugs 10201 are installed at both ends of the slot 10101.

[0039] The mounting strip 104 is made of insulating material.

[0040] It also includes a shielding plate 106; each wire comb 105 is provided with a clamping portion 10502; between adjacent wire combs 105 of two adjacent mounting plates 101, a shielding plate 106 is clamped via the clamping portion 10502.

[0041] Each wire comb 105 is provided with a sliding portion 10503 ; and a hook 10504 is provided at the lower portion of each wire comb 105 .

[0042] The working principle of the above embodiment is as follows:

[0043] When workers need to install the power distribution cabinet 1, they first plan the overall layout according to the electrical components that need to be installed; Figure 2 、 Figure 7 and Figure 9In the prior art, when installing electrical components and wiring on a flat plate, a wire trough is generally used and the wiring is S-shaped. For example, after the main line is connected to the electrical component relatively located on the upper left, a branch line is branched out, and the branch line is connected to another electrical component relatively located on the lower right, with two rows of electrical components between them. In the prior art, the branch line will be branched out from the electrical component on the upper left, and then extended downward to the layer where the electrical components on the next layer are located, and then horizontally extended to the right to the end, and then extended downward, and then extended to the left to the end, and finally extended downward to the layer where the target electrical component is located and extended to the right and connected to the target electrical component. The overall wiring is S-shaped, resulting in a longer wiring length overall. In order to solve the problem of long wiring, according to the location planning of the electrical components, first connect the connecting strip 10 9, a cable clip 107 is slidably installed on each of the opposite sides of 9. After the cable clip 107 is slid and assembled, it will be locked by the elastic clip 10902 to prevent the cable clip 107 from detaching by itself. When the cable clip 107 needs to be removed, it is only necessary to press the elastic clip 10902 so that the convex head on the surface of the elastic clip 10902 does not block the cable clip 107. Then, through the sliding groove 10901 of the connecting strip 109, several assembled connecting strips 109 are slid and installed on the back side and recessed side of the card slot 10101 of the mounting plate 101, maintaining a good interval, and then screwing in the bolts from the front side and protruding side of the card slot 10101 of the mounting plate 101 to fix the position of the connecting strip 109 and the cable clip 107, and finally fix the mounting plate 101 in the distribution cabinet 1.

[0044] Combine Figure 2 and Figure 7 The horizontal mounting plate 101 can be fixed in multiple layers to form an adjustment module. On the basis of the above, a horizontal bracket can be further fixed in the middle and bottom areas between the two vertical brackets 1002, and the mounting plate 101 can be fixed in an upright position between the two horizontal brackets. The mounting plate 101 fixed in an upright position also forms an adjustment module, and two types of adjustment modules can be installed in one distribution cabinet 1 at the same time.

[0045] like Figure 4As shown, when starting to install the electrical components, according to the pre-planned position, if there are no other problems, if there is a slot 10101 on the back of the electrical component that can cooperate with the J-shaped hook bent in two directions on the surface of the mounting plate 101, then directly slide the electrical component on the side of the protruding side of the mounting plate 101 into the slot 10101, and after reaching the predetermined position, screw the additional bolts through the bolt groove for positioning on the surface of the electrical component, press against the surface of the mounting plate 101, and lock it on the surface of the mounting plate 101 through friction; if there is no slot 10101 on the back of the electrical component, then fix the electrical component bolts on the mounting bar 104, and then slide the plug board 102 to the predetermined position, and then screw the bolts on the plug board 102 against the surface of the mounting plate 101 to fix the position of the plug board 102.

[0046] like Figure 5-Figure 7 As shown, when preparing to route the wires, you need to first insert the sliding part 10503 of the wire comb 105 into the slot at the end of the mounting plate 101, and then press the wire comb 105 so that the elastically deformable hook 10504 is buckled into the buckle groove at the end of the mounting plate 101, thereby fixing the wire comb 105 to the end of the mounting plate 101. The wire comb 105 can be clamped all over the end of the mounting plate 101, or it can be clamped correspondingly at the position where the electrical components are located. The wire comb 105 needs to be clamped at both the upper and lower ends of the mounting plate 101; when routing the wires, the branch wires are directly guided vertically from the inner side of the distribution cabinet 1 to the mounting plate 101 where the corresponding electrical components are located, and then turned horizontally to pass through the wire clamping groove 10701 of the cable clamp 107. After passing through to the appropriate position, it is bent upward and then passed through the upper wire threading groove 10501, transferred to the front side of the mounting plate 101, and finally connected to the upper side of the electrical components. The wires branching out from the lower end of the electrical components to the lower mounting plate 101 need to first pass through the lower wire threading groove 10501, transfer back to the back side of the mounting plate 101, and then extend downward in the back area of ​​the mounting plate 101, and then pass through the back side of the next mounting plate 101 through its wire threading groove 10501, pass through the front side of the next mounting plate 101 and connect to the electrical components on the next mounting plate 101; a distance needs to be maintained between the mounting plates 101. After the wiring is completed, the shielding plate 106 is pressed from the front to the back between the adjacent clamping parts 10502. The two wings of the shielding plate 106 are U-shaped and have the characteristic of elastic deformation. Therefore, after the shielding plate 106 is pressed in, under the extrusion of the adjacent clamping parts 10502, the shielding plate 106 is clamped between the upper and lower adjacent mounting plates 101 by utilizing the rebound force of the two wings of the shielding plate 106.

[0047] In this way, the wiring form of the branch line is L-shaped instead of the general S-shape, which can greatly reduce the wiring length; different wires are distinguished by cable clips 107 and wire combs 105 according to function, position and other standards, making the cables easy to find and easy to maintain later. Moreover, the cable clips 107 replace the traditional cable ties to concentrate the cables, and will not tie the cables completely. If a certain cable needs to be scrapped and replaced, the cable can be directly pulled out after removing the connections at both ends of the cable, which is convenient for replacement; the cables crossing between the upper and lower mounting plates 101 will be blocked by the shielding plate 106, so after all are assembled, from the outside, only various electrical components and the cable ends at their end positions are in view, and most of the cable bodies are hidden on the back of the mounting plate 101 and the shielding plate 106, and the interior of the entire distribution cabinet 1 is neat and beautiful.

[0048] Some of the terminals on the electrical components are connected to prefabricated copper busbars. However, when installing various electrical components of different sizes and specifications such as relays, air switches, and contactors on the same mounting plate 101, these electrical components have different lengths and other dimensions. Therefore, prefabricated copper busbars of uniform specifications cannot directly adapt to the connection between each electrical component and the PLC controller or power supply. Workers also need to perform secondary processing such as cutting and bending on the prefabricated copper busbars to adjust the length of the copper busbars, which greatly increases the complexity of the installation process. Therefore, Figure 2 and Figure 4 As shown: for electrical components that need to be connected to copper busbars, the wire comb 105 above them is removed. After the worker bolts the electrical components to the mounting bar 104, the worker can adjust the position of the mounting bar 104 according to the size of the electrical components. That is, when the electrical components are long, the mounting bar 104 and the electrical components are pulled downward, so that the upper surface of the longer electrical components is flush with the upper surfaces of other electrical components. When the electrical components are short, the mounting bar 104 and the electrical components are pulled upward, so that the upper surface of the shorter electrical components is flush with the upper surfaces of other electrical components. After the position adjustment of the mounting bar 104 and the electrical components is completed, the worker tightens the fixing screws on the mounting block 103 to fix the mounting bar 104 and the electrical components. Then, the distance between the upper surface of each electrical component on the mounting plate 101 and the PLC controller or power supply to be connected is the same. At this time, a unified prefabricated copper busbar can be used to connect and install electrical components of different sizes, which solves the problem that workers need to perform secondary processing such as cutting and bending on the prefabricated copper busbar, making the installation process more convenient and simple, and greatly improving the installation efficiency of the distribution cabinet 1.

[0049] On the basis of the above technical effects, the present invention also has the following advantages:

[0050] like Figure 3 and Figure 7As shown: the mounting plate 101 is arc-shaped, which is different from the existing straight plate installation. After the electrical components are installed, more gaps will be left between the rear side of the electrical components and the mounting plate 101 to facilitate heat dissipation of the electrical components.

[0051] like Figure 4 As shown: plugs 10201 are plugged into the left and right sides of the mounting plate 101; when the plug board 102 needs to be installed or removed, the worker only needs to remove the plugs 10201 on both sides of the mounting plate 101. Under normal circumstances, the plugs 10201 are used to prevent the plug board 102 from detaching from the mounting plate 101.

[0052] like Figure 4 As shown, the mounting strips 104 are made of insulating material. When a short circuit or leakage occurs in an electrical component on one of the mounting strips 104, the insulating mounting strip 104 prevents the current from being transmitted to the surrounding electrical components, thereby damaging the surrounding electrical components.

[0053] Example 2: Based on Example 1, Figure 2 and Figure 9 As shown, a horizontal bracket 1001 and a vertical bracket 1002 are provided in the distribution cabinet 1; four horizontal brackets 1001 are symmetrically bolted in the distribution cabinet 1; all the horizontal brackets 1001 on the same side are commonly bolted to the vertical bracket 1002; all the mounting plates 101 are bolted to the two vertical brackets 1002 through the connecting frame 10102.

[0054] The working principle of the above embodiment is as follows:

[0055] Combine Figure 2 and Figure 9 As shown, the vertical bracket 1002 is then bolted to the horizontal bracket 1001 of the power distribution cabinet 1 using bolts, two of which pass through the bolt holes of the horizontal bracket 1001 and are locked to the vertical bracket 1002, and one bolt is to pass directly through the vertical bracket 1002 and then cooperate with the nut to fasten itself to the vertical bracket 1002. The bolt head protrudes from the surface of the vertical bracket 1002 and is supported by the horizontal bracket 1001 as a bearing point. The three bolts together fix the vertical bracket 1002 to the horizontal bracket 100 1, a total of two vertical brackets 1002 are set on the left and right sides of the distribution cabinet 1; then, two L-shaped connecting brackets 10102 are slid into the back side and the two ends of the recessed side of the card slot 10101 of the mounting plate 101, and after adjusting to a suitable distance, the bolts are screwed into the fixing position from the front side and the protruding side of the card slot 10101 of the mounting plate 101, and finally the other ends of the connecting brackets 10102 are screwed to the two vertical brackets 1002 with bolts, and finally the mounting plate 101 is fixed in a horizontal suspended posture.

[0056] The distribution cabinet 1 is in a front-to-back through state, and the vertical bracket 1002 is installed in the middle of the distribution cabinet 1. The connecting frame 10102 can be symmetrically installed on the front and rear sides of the vertical bracket 1002, that is, the vertical bracket 1002 can be symmetrically installed with the mounting plate 101, thereby dividing the interior of the entire distribution cabinet 1 into two chambers on the front and rear sides for installing electrical components. Compared with the single-door distribution cabinet 1 in general, all electrical components are installed on a flat plate located deep in the distribution cabinet 1. This double-door, double-sided installation method utilizes the idle space near the cabinet door of the original single-door distribution cabinet 1, greatly improving the utilization rate of the internal space of the distribution cabinet 1; at the same time, workers can adjust the position of the vertical bracket 1002 forward and backward according to the size of the electrical components installed on the front and rear sides of the distribution cabinet 1, thereby changing the size of the space on the front and rear sides of the distribution cabinet 1, and reserving more space for the installation side of larger electrical equipment.

Any equivalent substitutions made within the principles of the present invention are intended to be included within the scope of protection of the present invention. Any content not elaborated in detail herein is already known to those skilled in the art.
