Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical control cabinets, more particularly, it relates to an electrical control cabinet. BACKGROUND

[0002] The electrical control cabinet is a core electrical control unit in the fields of industrial production, building, power system, etc. It mainly realizes the power supply control, circuit protection, signal conversion and operation state monitoring of various electrical equipment through the internal installation of circuit breakers, contactors, relays, frequency converters and other electrical components. It is usually configured with a special mounting plate inside to regularize and fix various electrical components, making the wiring orderly and the structure compact, which not only guarantees the stability and safety of circuit connection, but also provides basic conditions for later maintenance. The device is a key facility to ensure the smooth operation of electrical equipment and avoid electrical fault risks, directly affecting the reliability and operation efficiency of the entire electrical system, and is widely used in intelligent manufacturing, municipal engineering, energy supply and other scenarios.

[0003] However, the traditional electrical control cabinet has obvious defects in installation and maintenance convenience and operation safety, which is difficult to meet the actual use requirements. On the one hand, the mounting plate of the traditional control cabinet is mostly fixed by welding or bolt fastening structure, and is embedded in the inside of the cabinet, resulting in a small operating space in the cabinet. When installing new electrical components or maintaining and replacing existing components, the hands and tools of the operator are difficult to operate flexibly, especially for components in the deep part of the cabinet, the operation difficulty is extremely great, not only prolongs the installation and maintenance period, but also may cause component damage or line loosening due to improper operation. On the other hand, the electrical switch (including the main switch) of the traditional control cabinet is arranged together with other components in the inside of the cabinet. When the switch needs to be replaced due to damage, especially the main switch, it is often impossible to quickly cut off the power supply of the upper level or there is a situation that cutting off the power supply affects the operation of other associated equipment, which causes the operator to need to perform replacement operation in a live state; such live operation method is easy to cause electric shock, short circuit and other safety accidents, which seriously threatens the personal safety of the operator, and it is urgent to optimize the structure of the control cabinet to solve the above problems.

[0006] Preferably, the front of the installation plate is fixedly connected with an installation clamping rail, and the installation clamping rail is evenly distributed in a rectangular array.

[0007] Preferably, the lower surface of the first connecting seat is provided with a first wiring slot, and the lower end of the electrically conductive card is arranged in the first wiring slot.

[0008] Preferably, the upper surface of the second connecting seat is provided with a second wiring slot in front of the installation plate, and the second wiring slot is provided with a plurality of second wiring slots corresponding to the electrically conductive inner plug.

[0009] Preferably, the inner side wall of the second connecting seat is slidingly connected with a sliding plate, the rear of the sliding plate is fixedly connected with a plug rod in the middle of the electrically conductive inner plug, the rear end of the plug rod is fixedly connected with a pressing end, the inner side wall of the control cabinet body is rotatably connected with a spring telescopic rod through a shaft, and one end of the telescopic rod of the spring telescopic rod is rotatably connected to the upper surface of the second connecting seat through a shaft.

[0010] Preferably, the rear end of the sliding plate is fixedly connected with one end of the sliding plate, the rear end of the sliding plate is fixedly connected with a spring, and the rear end of the spring is in abutment with the inner side wall of the third sliding rail.

[0011] Preferably, the outer surface of the handle is sleeved with an insulating layer.

[0012] (Three) beneficial effects Compared with the prior art, the present invention provides an electrical control cabinet, which has the following advantages: 1. This electrical control cabinet, through the arrangement of a first slide rail, a first slider, a mounting plate, a second slide rail, a second connecting seat, and a spring telescopic rod, facilitates the installation and maintenance of internal components. Through the coordinated arrangement of the first slide rail, first slider, mounting plate, second slide rail, second connecting seat, connecting rod, handle, and spring telescopic rod, during use, the handle can be used to pull the third slide rail back and forth, causing the mounting plate to move forward from the inside of the control cabinet. This moves electrical equipment components originally located deep within the control cabinet to the front opening of the cabinet, facilitating the installation and maintenance of the electrical equipment components mounted on the mounting plate and expanding the working space.

[0013] 2. This electrical control cabinet, through the arrangement of a first connecting seat, a second connecting seat, a sliding plate, and an eccentric block, enhances its safety performance. The coordinated arrangement of the first connecting seat, conductive clip, second connecting seat, and second wiring groove allows the mounting plate to be pulled forward from the control cabinet during maintenance or equipment replacement. This moves the second connecting seat forward, disengaging the conductive insert from the conductive clip, thus automatically cutting off power to the electrical equipment and improving safety. Furthermore, after maintenance, the coordinated arrangement of the conductive insert, sliding plate, plug rod, and eccentric block enhances the connection stability between the conductive insert and the conductive clip, achieving the goal of automatically cutting off power to the electrical equipment during maintenance.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0019] Please see Figures 1-7 The electrical control cabinet provided in this embodiment has a first slide rail 5 fixedly connected to the inner wall of the cabinet body 1, a first slider 6 slidably connected to the inner wall of the first slide rail 5, a mounting plate 7 fixedly connected to the outer surface of the first slider 6, and several mounting rails 8 arranged in a rectangular array fixedly connected to the front of the mounting plate 7; a second slide rail 9 fixedly connected to the inner wall of the cabinet body 1 below the first slide rail 5, a second connecting seat 15 slidably connected to the inner wall of the second slide rail 9, and the rear of the second connecting seat 15 fixedly connected to the lower front side of the mounting plate 7; a spring telescopic rod 26 rotatably connected to the inner wall of the cabinet body 1 via a shaft, one end of the spring telescopic rod 26 rotatably connected to the upper surface of the second connecting seat 15 via a shaft; a third slide rail 20 fixedly connected to the front of both sides of the second connecting seat 15, an eccentric block 23 rotatably connected to the inner wall of the front end of the third slide rail 20, and a handle 25 (with an insulating layer sleeved on the outer surface of the handle 25) fixedly connected to the outer surface of the eccentric block 23 via a connecting rod 24, forming the core structure for convenient installation and maintenance of control cabinet components.

[0020] Specifically, first open cabinet door 4, hold handle 25 with insulation layer and pull forward. Connecting rod 24 drives eccentric block 23 to rotate, and its contact point with sliding plate 17 changes from the long axis to the short axis, reducing the squeezing force. Under the action of spring 22 and operator's pulling force, second connecting seat 15 slides forward along second slide rail 9. At the same time, mounting plate 7 moves forward synchronously along first slide rail 5 through first slider 6, pushing mounting plate 7 from deep inside control cabinet 1 to the front. At this time, mounting rail 8 in front of mounting plate 7 is fully exposed, greatly expanding the working space. Operators can flexibly install, disassemble or repair components without having to operate in a narrow cabinet. Spring telescopic rod 26 extends and provides a limit when mounting plate 7 moves forward, preventing first slider 6 from slipping from the front end of first slide rail 5. When moving backward to reset, it can assist in pushing mounting plate 7 back to its original position.

[0021] Please see Figures 1-7 The control cabinet body 1 of the electrical control cabinet has a first connecting seat 10 fixedly connected to the rear end of the second slide rail 9 on the inner side wall. The lower surface of the first connecting seat 10 is provided with a first wiring groove 11. The front of the first connecting seat 10 has several slots 12 arranged in a rectangular array. The inner side wall of the slots 12 is fitted with conductive cards 13 (the lower end of the conductive cards 13 is located in the first wiring groove 11). The rear of the second connecting seat 15 is fixedly connected with a conductive insert 16 that is compatible with the conductive card 13. The upper surface of the second connecting seat 15, located on the front side of the mounting plate 7, has several slots for connecting the conductive insert 16 to the conductive card 13. The second wiring slot 14 corresponds to the inner plug 16; a sliding plate 17 is slidably connected to the inner wall of the second connecting seat 15, and a plug rod 18 is fixedly connected to the middle of the conductive inner plug 16 behind the sliding plate 17, and a pressing end 19 is fixedly connected to the rear end of the plug rod 18; a sliding plate 17 is slidably connected to the inner wall of the third slide rail 20, and a spring 22 is fixedly connected to the rear end of the sliding plate 17 (the rear end of the spring 22 abuts against the inner wall of the third slide rail 20), which constitutes the key structure for automatic power-off and stable connection during control cabinet maintenance.

[0022] Specifically, external cables enter from the lower surface of the control cabinet 1, connect to the first wiring slot 11 of the first connector 10 and connect to the conductive clip 13. Cables of components on the mounting plate 7 connect to the second wiring slot 14 of the second connector 15 and connect to the conductive insert 16. When the mounting plate 7 moves forward for maintenance, it moves the second connector 15 synchronously, and the conductive insert 16 automatically disengages from the conductive clip 13, disconnecting the component circuit and achieving automatic power-off during maintenance to avoid electric shock or short circuit accidents caused by live operation. After maintenance, push the handle 25 backward to re-engage the conductive insert 16 into the conductive clip 13, and then pull the handle 25 upward. The long shaft end of the eccentric block 23 presses against the sliding plate 17, causing the sliding plate 17 to slide backward. The pressing end 19 at the rear end of the plug rod 18 presses the conductive insert 16 to both sides, making the conductive insert 16 fit tightly against the conductive clip 13, improving the stability of the circuit connection and preventing poor contact. The spring 22 can assist the sliding plate 17 in resetting when the eccentric block 23 loosens, ensuring connection reliability.

[0023] In summary, when using the entire equipment: First, open the cabinet door 4, then pull the handle 25 forward. The connecting rod 24 will first rotate to the horizontal direction. At this time, the contact point between the outer surface of the eccentric block 23 and the sliding plate 17 will shift from the long axis to the short axis, reducing the squeezing force on the front end of the sliding plate 17. The sliding plate 17 will be pushed forward by the spring 22, causing the squeezing end 19 to disengage from the squeezing of the conductive insert 16. Then, continue to pull the handle 25 forward, which will move the second connecting seat 15 forward. The conductive insert 16 will disengage from the inner wall of the conductive clip 13 until the mounting plate 7 moves to the front opening of the control cabinet 1, increasing the working space in front of the mounting plate 7 to facilitate the installation of electrical equipment. Install the electrical equipment on the mounting rail 8, and then connect the wires. The cables enter the interior of the control cabinet 1 from the lower surface of the control cabinet 1, and then are installed... Inside the first wiring slot 11, the incoming and outgoing lines of the electrical equipment are installed in the second wiring slot 14. After installation, push the handle 25 backward, and the conductive insert 16 behind the second connector 15 is inserted into the conductive card 13. Then, pull the handle 25 upward, and the contact point between the eccentric block 23 and the sliding plate 17 moves from the short axis to the long axis, thereby pushing the sliding plate 17 to move backward. This causes the sliding plate 17 to slide backward, so that the pressing end 19 at the rear end of the plug rod 18 is pressed to both sides in the middle of the conductive insert 16, improving the stability of the connection between the conductive insert 16 and the conductive card 13, preventing poor contact. In addition, during maintenance, the setting of the connecting rod 24 and the handle 25 can prevent the operator from getting too close to the distribution cabinet, improving the safety of maintenance operations. The setting provides thrust when moving to the rear end and provides a limit when moving to the front end to prevent slipping from the front end.

[0024] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
