Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an electrical cabinet with a wire end protection function. Background Art

[0002] As a key component of the power system, electrical cabinets are widely used in industrial, commercial and residential fields, responsible for the distribution and control of electric energy. However, traditional electrical cabinets have exposed some obvious problems in actual operation, mainly focusing on the convenience of component installation, the safety of wire protection, and the complexity of subsequent maintenance.

[0003] First, there are various ways to install components in electrical cabinets. For example, the power switch can be connected to the mounting plate in the cabinet through its own card slot, or it can be connected to the mounting plate screws through the threaded holes. Although this diversity provides a certain degree of flexibility, it also brings limitations. In particular, the card connection method limits the size of the mounting plate. When installing larger components such as relays, additional pads are required, which increases the complexity of installation.

[0004] Secondly, maintenance or new needs after component installation become inconvenient due to the diversity of the original installation methods. In addition, the connection between components usually relies on their own connection holes, and it is common for multiple wires to share the same connection hole. This not only leads to looseness or poor contact during maintenance, but may also cause it to fall off when it is bumped or shaken; when installing new components, it is often difficult to connect the wires to the connection holes, which increases the difficulty of operation and safety hazards. Furthermore, due to the influence of the original installation method, when installing new components, the layout will be too crowded and the components will be arranged unreasonable.

[0030] Embodiment 1

[0031] Referring to 1 and 2, an electrical cabinet with a wire end protection function comprises a cabinet body 1 and components 4;

[0032] See also Figure 2, 3 , further comprising a mounting assembly 2, the mounting assembly 2 comprising a clamping mechanism 3, a mounting plate 21 and a moving block 22; a first spring 23 is provided between the mounting plate 21 and the moving block 22, and the relative position of the mounting plate 21 and the moving block 22 is controlled by the first spring 23; a fixing hole 211 is provided on the mounting plate 21, and the fixing hole 211 is connected to the fixing head 34; a moving hole 221 is provided on the moving block 22, and the moving hole 221 is connected to the moving head 35; the movement of the clamping mechanism 3 is controlled by the mounting plate 21 and the moving block 22. Specifically, the fixing hole 211 on the mounting plate 21 is connected to the fixing head 34 on the back of the sliding rod 33, and the moving hole 221 on the moving block 22 is connected to the moving head 35 of the first transmission rod 32, and the movement of the clamping mechanism 3 is controlled together. The mounting plate 21 has a mounting window 24 and a mounting groove 25, and the mounting window 24 is connected to the mounting groove 25; the moving block 22 is arranged in the mounting window 24, and the first spring 23 is arranged in the mounting groove 25; the relative position between the mounting plate 21 and the moving block 22 is controlled by the first spring 23 to ensure the stability of the clamping mechanism 3 when holding components 4 of different sizes.

[0033] Both ends of the installation window 24 and the installation groove 25 are provided with a limiting groove 26 and a limiting protrusion 27, and both ends of the moving block 22 are provided with a sliding groove 28 and a sliding protrusion 29, respectively. The limiting groove 26 and the sliding protrusion 29 cooperate, the sliding groove 28 and the limiting protrusion 27 cooperate, and the sliding groove 28 and the sliding protrusion 29 between adjacent moving blocks 22 cooperate to realize the installation plate 21 and the moving block 22. Specifically, the limiting grooves 26 at both ends of the installation window 24 and the installation groove 25 cooperate with the sliding protrusions 29 at both ends of the moving block 22 to limit the lateral movement of the moving block 22 and ensure its smooth movement in the vertical direction. The cooperation between the slide groove 28 of the moving block 22 and the limiting protrusion 27 in the mounting groove 25, as well as the cooperation between the slide groove 28 and the sliding protrusion 29 between adjacent moving blocks 22, enable the moving block 22 to move smoothly within the predetermined track while maintaining a stable connection with the mounting plate 21, thereby reducing the probability of loosening and falling off of the terminal of the component 4.

[0034] See also Figure 4The clamping mechanism 3 is used to fix the components 4. The cooperation between the installation assembly 2 and the clamping mechanism 3 can solve the problem of overcrowding after the components 4 are installed, realize a reasonable layout, improve the space utilization rate inside the electrical cabinet, and reduce the maintenance difficulty and safety hazards caused by unreasonable layout. The clamping mechanism 3 includes a clamping plate 31 and a first transmission rod 32; the clamping plate 31 is located at both ends of the component 4, and the clamping plate 31 is set on the slide bar 33 and can move on the slide bar 33 to adapt to components 4 of different sizes; the back of the slide bar 33 is provided with a fixing head 34, and the fixing head 34 cooperates with the fixing hole 211 on the mounting plate 21 to fix the clamping mechanism 3. One end of the first transmission rod 32 is swingably connected to the clamping plate 31, and the other end of the first transmission rod 32 is rotationally connected to the moving head 35; when the fixed head 34 and the moving head 35 are far apart, the clamping plates 31 are close to each other, so that the clamping mechanism 3 fixes the component 4; through the relative movement of the moving head 35 and the fixed head 34, the opening and closing of the clamping plate 31 is controlled to clamp the component 4. Limit blocks 36 are provided at both ends of the slide rod 33 in the clamping mechanism 3, and the limit blocks 36 are used to prevent the clamping plate 31 from falling off; preventing the clamping plate 31 from accidentally falling off during the sliding process, ensuring the stability and safety of the clamping mechanism 3 during operation. A slide rail 37 perpendicular to the slide rod 33 is provided in the middle of the slide rod 33, which provides a moving track for the moving head 35, ensuring that the moving head 35 moves along a predetermined path driven by the first transmission rod 32, thereby controlling the opening and closing of the clamping plate 31. The moving head 35 is arranged on the slide rail 37, and the fixed head 34 is located on the vertical line between the slide rod 33 and the slide rail 37. The clamping plate 31 is extended inward at the bottom end to form an extension protrusion 38, and the extension protrusion 38 is used to limit the bottom end of the component 4 to prevent the component 4 from sliding or tilting during the clamping process.

[0035] The end of the first transmission rod 32 connected to the moving head 35 is provided with connection holes 321 at equal intervals, and the connection holes 321 are used to realize the connection between the first transmission rod 32 and the moving head 35; the moving head 35 is connected to the corresponding connection holes 321, so that the degree of proximity of the clamping plate 31 can be controlled when the fixed head and the moving head 35 are far apart. The moving head 35 can be docked with different connection holes 321 as needed, so as to realize precise control of the degree of proximity of the clamping plate 31. This design allows the user to fine-tune the clamping force according to the size and shape of the component 4, thereby improving the adaptability and flexibility of the clamping mechanism 3.

[0036] See also Figure 2 , 5, 6, also includes a support component 5, the support component 5 is used to fix the position of the installation component 2 in the cabinet 1; the support component 5 includes a telescopic rod, so that the support component 5 can be vertically fixed in the cabinet 1 at different heights; a second spring 53 is provided in the telescopic rod, and the second spring 53 provides a contraction space for the support component 5, so that the support component 5 can be vertically fixed in the cabinet 1, ensuring the adaptability and stability of the support component 5.

[0037] The telescopic rod includes a sleeve 51 and an inner rod 52, one end of the inner rod 52 is located inside the sleeve 51 and connected to the second spring 53, and the other end of the inner rod 52 is located outside the sleeve 51 and is provided with a first docking ear 54; the support assembly 5 also includes an adjusting screw 55, both ends of the adjusting screw 55 have a first thread and a second thread, and the threads of the first thread and the second thread are opposite; the two ends of the adjusting screw 55 are respectively provided with a first nut 56 and a second nut 57, the first nut 56 is screwed with the first thread, and the second nut 57 is screwed with the first thread. The second thread is screwed together; when the adjusting screw 55 rotates, the first nut 56 and the second nut 57 will approach or move away from each other; the first nut 56 and the second nut 57 are both provided with a second docking ear 58, and a second transmission rod 59 is provided between the first docking ear 54 and the second docking ear 58; when the first nut 56 and the second nut 57 are close to each other, the second transmission rod 59 will compress the inner rod 52, thereby compressing the second spring 53, so that the support assembly 5 is firmly fixed in the cabinet 1, thereby ensuring that the support assembly 5 is firmly fixed in the cabinet 1.

[0038] Specifically, the presence of the second spring 53 provides the necessary elasticity for the telescopic rod, so that the support assembly 5 maintains a certain preload when it is not fully extended, so that it can better adapt to the depth change of the cabinet 1 during installation, and ensure the stable fixation of the installation assembly 2. Then, by adjusting the setting of the screw 55, after the support assembly 5 is arranged in the cabinet 1, the preload of the support assembly 5 can be increased by adjusting the screw 55, and the stable fixation of the installation assembly 2 can be further ensured. The advantage of installing the support assembly 5 by using a spring and a mechanical structure is that the second spring 53 can absorb vibration and impact, which can reduce damage or failure caused by vibration, extend the service life of the equipment, and reduce the probability of loosening and falling off of the terminal of the component 4. In the initial stage, the support assembly 5 may not have a large preload, so that in the initial stage of arrangement, the support assembly 5 can be more easily inserted or adjusted to the desired position, avoiding installation difficulties caused by excessive preload. Once positioned, the preload can be increased by adjusting the screw 55 to ensure that the assembly is firmly fixed. By adjusting the preload force, the support assembly 5 can adapt to various installation conditions, whether it is a narrow space or an occasion requiring stronger support force; and the appropriate preload force can ensure that the support assembly 5 is not easy to loosen during use, reducing the safety hazards caused by loose fixation, especially in an environment with frequent vibration or movement.

[0039] See also Figure 2 , 7 One side of the telescopic rod is provided with a connection mechanism 6 at equal intervals in the vertical direction, and the connection mechanism 6 is an important bridge between the support assembly 5 and the mounting assembly 2. The connection mechanism 6 includes a connection block 61 with a connection groove 62; both ends of the mounting plate 21 are provided with a docking block 67, and the docking block 67 is placed in the connection groove 62 to achieve the connection between the support assembly 5 and the mounting assembly 2.

[0040] The connection groove 62 is located at the top of the connection block 61. The connection block 61 has installation cavities 63 at both ends of the connection groove 62. The installation cavities 63 are connected to the connection groove 62 and directly pass through the bottom of the connection block 61. A control rod 64 is arranged in the installation cavity 63. The middle part of the control rod 64 is rotatably installed in the installation cavity 63. The bottom end of the control rod 64 extends out of the installation cavity 63 and is connected to a third spring 65, which provides the necessary elastic force for the control rod 64, ensures the close contact between the control docking protrusion 66 and the docking groove 671, and can also buffer the looseness caused by external factors (such as vibration) to enhance the stability of the connection. The top of the control rod 64 has a control docking protrusion 66. The docking block 67 has docking grooves 671 on both sides. When the docking protrusion 66 is located in the docking groove 671, the connection and fixation of the connection mechanism 6 and the docking block 67 are achieved. When the docking protrusion 66 is controlled to accurately enter the docking groove 671, the control rod 64 remains stable under the action of the third spring 65, and the connection mechanism 6 and the docking block 67 are tightly connected, thereby ensuring the firm fixation between the support assembly 5 and the mounting assembly 2. The control rod 64 is rotatably installed in the mounting cavity 63, and a certain elastic force is maintained at its bottom end by the third spring 65. After the docking block 67 and the connecting block 61 are preliminarily connected, the control docking protrusion 66 enters the docking groove 671, and the elastic force of the control rod 64 helps to achieve a stable connection.

[0041] A fourth spring 68 is provided at the bottom end of the connection groove 62, and a control plate 69 is provided on the fourth spring 68; when the docking protrusion 66 is disengaged from the docking groove 671, the fourth spring 68 is used to eject the docking block 67 from the connection mechanism 6. When the connection needs to be released, the docking protrusion 66 is controlled to be disengaged from the docking groove 671. At this time, the fourth spring 68 at the bottom end of the connection groove 62 acts on the control plate 69 to quickly eject the docking block 67 from the connection mechanism 6, thereby realizing quick disassembly.

[0042] Embodiment 2

[0043] An electrical cabinet with a wire end protection function. Compared with the electrical cabinet in the first embodiment, the electrical cabinet in this embodiment further defines the fixed hole 211 and the movable hole 221 as well as the fixed head 34 and the movable head 35. The specific conditions are as follows:

[0044] The fixed hole 211 and the movable hole 221 are both docking holes, and the fixed head 34 and the movable head 35 are both docking heads; ensuring that the mounting plate 21 and the movable block 22 control the clamping mechanism 3 to firmly fix the component 4. The specific structure of the docking hole and the docking head is not shown in the figure. Specifically, the above-mentioned setting can enhance the control of the mounting plate 21 and the movable block 22 on the clamping mechanism 3, ensuring that the component 4 is fixed more firmly and stably in the electrical cabinet; even when the electrical cabinet is subjected to external vibration or impact, the component 4 can be stably fixed. The cooperation of the docking hole and the docking head can not only realize quick installation and disassembly, but also provide additional support force during the fixing process of the component 4, reducing the risk of loosening due to improper installation or long-term use.

[0045] Embodiment 3

[0046] An electrical cabinet with a wire end protection function. Compared with the electrical cabinet in the first embodiment, the electrical cabinet in this embodiment has a new external connector to solve the problem of poor contact caused by multiple wires sharing a connection hole 321 in the prior art. The specific situation is as follows:

[0047] The clamping mechanism 3 also includes an external connector; the structure of the external connector can refer to the wiring terminal, and no further description is given here. The external connector has a wire connected to the component 4 and an external terminal electrically connected to the wire. The wire of the external connector is connected to the component 4, and then the external terminal is used to connect the external line that is originally connected to the component 4; so that the installation of the component 4 no longer depends on the complex connection hole 321, but the electrical connection is achieved through the wire directly connected to the external connector; avoiding the loosening and falling problems that may occur when multiple wires share the connection hole 321. At the same time, in terms of safety, the external connector is used as a bridge for connecting the external line of the component 4. When the component 4 needs to be replaced or upgraded, the rapid reconnection capability of the external connector also ensures quick and safe operation. At the same time, compared with the situation where multiple wires share the connection hole 321, allowing the line to be directly connected to the external connector can provide better feedback connection; it is convenient for regular inspection and maintenance, and timely discovery and elimination of potential safety problems.

[0048] Embodiment 4

[0049] A method for using an electrical cabinet with a wire end protection function, specifically relating to the electrical cabinets in Embodiment 1, Embodiment 2, and Embodiment 3;

[0050] Place the component 4 in the middle of the clamping plate 31 in the clamping mechanism 3; place the component 4 to be installed between the clamping plates 31 of the clamping mechanism 3. At this time, the clamping plates 31 are in an unclosed state to facilitate the smooth placement of the component 4. When placing, ensure that the component 4 is in the proper position for subsequent fixing operations. And push the clamping plates 31 to temporarily fix the component 4; gently push the clamping plates 31 so that they gradually approach the component 4 and clamp it preliminarily. This process requires moderate force to ensure that the component 4 can be clamped, but not to the extent of causing damage to the component 4. The fixation at this time is temporary in nature, mainly to facilitate the next step of operation.

[0051] The moving head 35 is built into the moving hole 221, and the fixed head 34 is built into the fixed hole 211 by pulling down; the moving head 35 is placed in the moving hole 221, and then the fixed head 34 is embedded in the fixed hole 211 by pulling down. The mechanical linkage ensures the stability of the clamping mechanism 3 and the precise alignment of the fixed head 34 and the moving head 35, providing a basis for the subsequent clamping force.

[0052] The clamping force of the clamping mechanism 3 on the component 4 is provided by the first spring 23 when the pushing force on the clamping plate 31 is cancelled; the pushing force on the clamping plate 31 is released, and the first spring 23 starts to work, generating an inward clamping force, so that the clamping plate 31 moves further inward, tightly clamping the component 4, and achieving a stable fixation. The force provided by the first spring 23 ensures the safety and stability of the component 4 throughout the entire use cycle. At the same time, the elasticity of the spring can also adapt to slight changes in the size of the component 4, ensuring that a good clamping effect is always maintained.

[0053] Embodiment 5

[0054] A method for using an electrical cabinet with a wire end protection function, specifically relating to the electrical cabinets in Embodiment 1, Embodiment 2, and Embodiment 3;

[0055] Adjust the first nut 56 and the second nut 57 to be apart, and then place the support assembly 5 in the cabinet 1; before starting to install the support assembly 5, first adjust the first nut 56 and the second nut 57 to be apart from each other. The purpose is to make it easier to insert or adjust the support assembly 5 to the desired position, avoiding installation difficulties caused by excessive preload. Leave enough space for the installation of the support assembly 5 to facilitate subsequent placement and preliminary fixation. By turning the adjusting screw 55, the first nut 56 and the second nut 57 are separated along the axial direction of the screw. At this time, the preload of the support assembly 5 is minimal, which is easy to operate.

[0056] The support assembly 5 is initially fixed by adjusting the telescopic rod; the first nut 56 and the second nut 57 are adjusted to be close to each other, and the telescopic rod is contracted to achieve the final fixation of the support assembly 5. After the support assembly 5 in the relaxed state is placed at a designated position in the electrical cabinet; the first nut 56 and the second nut 57 are adjusted to be close to each other, and the second transmission rod 59 compresses the second spring 53, so that the inner rod 52 of the telescopic rod is contracted into the sleeve 51, thereby applying a pre-tightening force to the support assembly 5, and achieving the final fixation of the support assembly 5. At this time, a stable connection is formed between the support assembly 5 and the wall of the electrical cabinet, ensuring the firmness and stability of the mounting assembly 2.

[0057] The technical effects of the present invention are mainly reflected in the following aspects: the electrical cabinet overcomes the complexity and limitations brought by the various installation methods of components 4 in the traditional electrical cabinet through the cooperation of the clamping mechanism 3 and the installation component 2. Through the coordinated work of the components such as the clamping plate 31, the sliding rod 33, the first transmission rod 32, etc., the components 4 are installed quickly and accurately, and the installation efficiency and flexibility are improved. The support component 5 makes it easier to fix and adjust the components inside the electrical cabinet through the cooperation of the spring and the mechanical structure; in the initial stage, the support component 5 may not have a large preload force, so that in the initial stage of layout, the support component 5 can be more easily inserted or adjusted to the required position, avoiding the installation difficulties caused by excessive preload force. Once positioned, the preload force can be increased by adjusting the screw 55 to ensure that the component is firmly fixed. By adjusting the preload force, the support component 5 can adapt to various installation conditions, whether it is a narrow space or an occasion that requires stronger support force; and the appropriate preload force can ensure that the support component 5 is not easy to loosen during use, reducing the safety hazards caused by loose fixation, especially in an environment with frequent vibration or movement.

[0058] In addition, as common knowledge in the industry, the wiring terminals, components 4 and cabinet 1 mentioned above are common knowledge, so their principles and structures will not be described in detail.

[0059] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
