Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinet installation structures, and specifically provides an installation structure for electrical components of a distribution cabinet. Background Art

[0002] The installation structure of electrical components in a distribution cabinet is a structure for fixing electrical components, ensuring the safe, reliable, and efficient operation of the electrical system, and the installation structure of electrical components directly affects the reliability, seismic resistance, maintenance convenience, and long-term stability of the system.

[0003] The traditional installation method is to install through rails. Modular components such as circuit breakers, contactors, and PLCs are quickly fixed on the rails by means of snap connection without the need for drilling, which is convenient for replacing components.

[0004] However, in the traditional rail installation structure, only relying on the elastic fixation of the rail buckle, when encountering vibrations caused by external adverse factors (such as earthquakes, wind, and offshore platforms), it is easy for components to shift or have poor contact, thus affecting the installation stability of electrical components and the reliability of long-term operation. Moreover, the traditional installation structure only fixes electrical components and does not fix the wires connected to the electrical components. During long-term operation, the wires may become loose from the terminal block or the component wiring port due to vibrations, thermal expansion and contraction (especially in the case of insecure crimping or without using wire noses), and the exposed wires contacting the cabinet body or other conductors are likely to cause short circuits. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention provide an installation structure for electrical components of a distribution cabinet to solve the technical problems in the related art.

[0006] To achieve the above object, embodiments of the present invention provide the following technical solution: an installation structure for electrical components of a distribution cabinet, including: a rail, a clamping and locking part, a pressing and locking part, and a pushing and locking part. Fixed frames are installed at both ends of the rail, and waist-shaped slots are provided on the fixed frames to facilitate the connection of the rail to the distribution cabinet through the waist-shaped slots on the fixed frames later.

[0007] The rail is composed of a fixed strip and symmetrically arranged upper and lower clamping strips installed on one side along its thickness direction. The clamping and locking part, the pressing and locking part, and the pushing and locking part are all installed on the fixed strip.

[0008] The clamping and locking part includes wire clamping and supporting components installed on both the upper and lower sides of the fixed strip and pressing components arranged on the wire clamping and supporting components; the pressing and locking part includes installation slots opened on both the upper and lower sides of the fixed strip, with inclined pressing plates rotatably connected to the installation slots, and a pushing component is also installed on the fixed strip.

[0009] The component is clamped on the upper and lower clamping bars through the buckle installed thereon, and the wires connected to the component are clamped on the wire clamping and supporting assembly. After the multiple components and their wires are limited in position, the pressing assembly elastically presses and fixes the wires on the wire clamping and supporting assembly, and then the multiple components clamped on the clamping bars are pushed against each other by pushing the locking part.

[0010] At the same time, the pushing and locking part also drives the pushing and pressing assembly through the linkage assembly and locks the pressing assembly. Under the combined action of the pushing and locking part and the linkage assembly, the pushing and pressing assembly drives the swing of the rotation connection of the inclined pressing plate and presses the buckle clamped on the clamping bar against the clamping bar again.

[0011] In a possible implementation manner, the wire clamping and supporting assembly includes brackets symmetrically arranged along the length direction on both the upper and lower sides of the fixed bar. A connecting shaft is installed between two corresponding fixed bars in the horizontal direction, and a plurality of wire clamping members are installed on the connecting shaft and arranged uniformly along its axis. The wire clamping members are used to limit the wires on the component; the wire clamping member is composed of a supporting wheel and annular rubber clamping rings fixedly installed at both axial ends thereof.

[0012] In a possible implementation manner, the pressing assembly includes a pressing plate slidably connected up and down between two corresponding brackets in the horizontal direction. Lifting guide grooves for slidably connecting with the pressing plate are formed on the brackets. A return spring is installed between the lifting guide grooves and the pressing plate. The pressing plate is parallel to the connecting shaft. Pressing blocks corresponding to the wire clamping members one by one are installed on the pressing plate. An arc-shaped clamping groove is formed on one side of the pressing block close to the supporting wheel.

[0013] In a possible implementation manner, the pushing and locking part includes two sliding grooves symmetrically arranged along the length direction on the fixed bar. A rotating rod is rotatably connected between the two sliding grooves. A moving frame is slidably connected to the sliding grooves. The moving frame is connected to the rotating rod in a threaded fit manner. Push members slidably connected to the fixed bar are fixedly installed on the opposite surfaces of the two moving frames.

[0014] In a possible implementation manner, the push member is composed of a fixed cylinder, a pressing seat slidably connected to the fixed cylinder, and a first spring installed between the fixed cylinder and the pressing seat. The fixed cylinder is fixedly connected to the moving frame.

[0015] In a possible implementation manner, the linkage assembly includes a pushing member and a locking member installed on the moving frame. The pushing member is used to push the pushing and pressing assembly towards the inclined pressing plate to drive the inclined pressing plate to press on the buckle, and the locking member is used to lock the position of the pressing plate pressing on the wire.

[0016] In a possible implementation manner, the pushing component includes pushing frames connected to both the upper and lower sides of the fixed strip. The pushing frames slide along the thickness direction of the fixed strip. A traction shaft is rotatably connected to one side of the pushing frame close to the inclined pushing plate. A guiding groove penetrating through both ends in the length direction is formed on the inclined pushing plate. The traction shaft slidably penetrates into the guiding groove, and the guiding groove and the traction shaft are slidably matched to drive the inclined pushing plate to swing around the rotation connection point of the inclined pushing plate when the pushing frame moves.

[0017] In a possible implementation manner, the pushing member includes an ear plate and a pushing rod. Opposite surfaces of the upper and lower two pushing frames are both provided with slots symmetrically arranged along their length directions. Opposite surfaces of two corresponding slots in the horizontal direction are both provided with inclined slots. Guide grooves communicating with the corresponding slots are both formed on both the upper and lower sides of the sliding groove. The ear plate is installed on the moving frame and penetrates through the guide groove and then into the slot. The pushing rod is installed on the ear plate and is used to push the inclined slot to drive the pushing frame to move. A return spring is installed between the fixed strip and the pushing frame.

[0018] In a possible implementation manner, the locking member includes symmetrically arranged upper and lower L-shaped plates installed at one end of the moving frame away from the pushing member. A sleeve hole for sleeving the end of the pressing plate is formed at the end of the L-shaped plate. The moving frame drives the L-shaped plate to move, and the L-shaped plate is sleeved on the end of the pressing plate through the sleeve hole, thereby realizing the locking of the L-shaped plate.

[0019] One or more of the above technical solutions in the embodiments of the present invention have at least the following beneficial effects: 1. An installation structure for electrical components of a power distribution cabinet designed by the present invention cooperates the pressing and locking part with the pushing and locking part, thereby further pressing and strengthening the buckle of the component clamped on the guide rail and tightly pressing the components against each other, preventing the components from sliding along the length direction of the guide rail under the action of vibration force. Under the action of multiple fixing forces, the stability of the component installation and fixation and the reliability of the work are greatly improved. And the cooperation of the pushing and locking part and the clamping and locking part also supports, fixes and locks the wire, preventing the wire from shaking and detaching from the component under external factors and affecting the reliability of the direct connection between the component and the wire.

[0020] 2. The pushing and locking part in the present invention can not only push and tightly press the components, but also drive the pressing and locking part to secondarily fix the components by the linkage component and lock the pressing component. Under the combined action of the pushing and locking part and the linkage component, the pushing component drives the rotation connection point of the inclined pushing plate to swing and presses the buckle stuck on the card strip against the card strip again, thereby realizing the integration drive of the secondary fixation, pushing and tight pressing of the components and the fixation of the wire.

Detailed implementation manner

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Refer to Figure 1 , an electrical component installation structure for a power distribution cabinet, including: a guide rail 1, a clip locking part 2, a pressing and locking part 3 and a pushing and locking part 4. Fixed frames are installed at both ends of the guide rail 1, and waist-shaped grooves are formed in the fixed frames to facilitate the connection of the guide rail 1 to the power distribution cabinet through the waist-shaped grooves in the fixed frames later.

[0035] Refer to Figure 1 , the guide rail 1 is composed of a fixing strip 10 and symmetrically arranged upper and lower clamping strips 11 installed on one side along its thickness direction, and the clip locking part 2, the pressing and locking part 3 and the pushing and locking part 4 are all installed on the fixing strip 10.

[0036] Refer to Figure 1 , Figure 5 and Figure 6, the clip locking part 2 includes a wire clamping and supporting component 20 installed on both the upper and lower sides of the fixed strip 10 and a pressing component 21 arranged on the wire clamping and supporting component 20; the pressing and locking part 3 includes installation grooves 30 opened on both the upper and lower sides of the fixed strip 10, an inclined pressing plate 31 is rotatably connected to the installation grooves 30, and a pushing component 32 is also installed on the fixed strip 10.

[0037] The component 6 is clamped on the upper and lower two clamping strips 11 through the buckle 60 installed thereon, and the wire 61 connected to the component 6 is clamped on the wire clamping and supporting component 20. After a plurality of components 6 and the wires 61 thereon are all limited, the pressing component 21 elastically presses and fixes the wire 61 on the wire clamping and supporting component 20, and then the pushing and locking part 4 is used to push a plurality of components 6 clamped on the clamping strip 11 to be pressed against each other, so as to prevent the components 6 from moving along the length direction of the guide rail 1 due to external factors and affecting the installation stability of the components 6.

[0038] Refer to Figure 1 , Figure 5 and Figure 6 , at the same time, the pushing and locking part 4 also drives the pushing component 32 through the linkage component 5 and locks the pressing component 21. The pushing component 32 drives the inclined pressing plate 31 to swing at the rotation connection part under the cooperation of the pushing and locking part 4 and the linkage component 5 and presses the buckle 60 clamped on the clamping strip 11 against the clamping strip 11 again, further improving the installation stability of the component 6. At the same time, the linkage component 5 also locks the pressing component 21, thereby improving the fixing and connection stability of the wire 61.

[0039] Refer to Figure 1 , Figure 2 and Figure 3 , the wire clamping and supporting component 20 includes brackets 201 symmetrically arranged along its length direction and installed on both the upper and lower sides of the fixed strip 10. A connecting shaft 202 is installed between two corresponding fixed strips 10 in the horizontal direction, and a plurality of wire clamping members 203 are uniformly arranged along the axial direction of the connecting shaft 202. The wire clamping members 203 are used to limit the wire 61 on the component 6; the wire clamping member 203 is composed of a supporting wheel 221 and annular rubber clamping rings 220 fixedly installed at both axial ends thereof.

[0040] Refer to Figure 1 , Figure 2 and Figure 3 , the pressing component 21 includes a pressing plate 210 slidably connected up and down between two corresponding brackets 201 in the horizontal direction. A lifting guide groove 211 for slidably connecting with the pressing plate 210 is opened on the bracket 201. A return spring 213 is installed between the lifting guide groove 211 and the pressing plate 210. The pressing plate 210 is parallel to the connecting shaft 202. Pressing blocks 214 corresponding to the wire clamping members 203 one by one are installed on the pressing plate 210. An arc-shaped clamping groove is opened on one side of the pressing block 214 close to the supporting wheel 221.

[0041] After the component 6 is stuck on the guide rail 1, pull the pressing plate 210 to move away from the connecting shaft 202, so that the wire 61 is stuck on the wire clamping member 203. Then, clamp the wire 61 on the component 6 between the annular rubber gaskets 220 on both sides of the supporting wheel 221. The two annular rubber gaskets 220 limit the wire 61 to prevent the wire 61 from moving randomly and affecting the installation of the component 6. At the same time, it is convenient for the installation and connection of the wire 61. After all the wires 61 are placed, release the pressing plate 210. The pressing plate 210 drives the pressing block 214 to press against the wire 61 under the elastic force of the return spring 213. The pressing block 214 cooperates with the supporting wheel 221 to fix the wire 61.

[0042] Refer to Figure 1 and Figure 2 As shown in FIGS.

[0043] Refer to Figure 2 and Figure 4 The pushing and locking part 4 includes two chutes 40 symmetrically arranged along the length direction on the fixing bar 10. A rotating rod 41 is rotatably connected between the two chutes 40. A moving frame 42 is slidably connected to the chute 40. The moving frame 42 is connected to the rotating rod 41 by a threaded fit. Pressing members 43 slidably connected to the fixing bar 10 are fixedly installed on the opposite surfaces of the two moving frames 42.

[0044] After the component 6 and the wire 61 are all placed and fixed, rotate the rotating rod 41. The rotating rod 41 drives the two moving frames 42 to move relatively through its threaded fit with the moving frame 42. During the movement of the moving frame 42, the pushing member 43 is driven to move towards the component 6, so as to tightly press the multiple components 6 on the strip 11 against each other, avoiding the movement of the component 6 along the length direction of the guide rail 1 due to external factors and affecting the installation stability of the component 6.

[0045] At the same time, the first spring 432 between the fixed cylinder 430 and the pressing seat 431 enables there to be a certain elastic force between the fixed cylinder 430 and the pressing seat 431, preventing damage to the component 6 when pressing the component 6 tightly.

[0046] Refer to Figure 2 , Figure 5 and Figure 6, the linkage component 5 includes a pushing member 50 and a locking member 51 mounted on the moving frame 42. The pushing member 50 is used to push the pushing and pressing component 32 towards the inclined pressing plate 31 to drive the inclined pressing plate 31 to press against the buckle 60, and the locking member 51 is used to lock the position of the pressing plate 210 pressing on the wire 61.

[0047] Refer to Figure 2 , Figure 5 and Figure 6 , the pushing and pressing component 32 includes pushing and pressing frames 320 connected to both the upper and lower sides of the fixed bar 10. The pushing and pressing frames 320 slide along the thickness direction of the fixed bar 10. A traction shaft 321 is rotatably connected to the side of the pushing and pressing frame 320 close to the inclined pressing plate 31. A guiding groove 322 penetrating through both ends in its length direction is formed on the inclined pressing plate 31. The traction shaft 321 slidably penetrates into the guiding groove 322. The guiding groove 322 and the traction shaft 321 are slidably matched to drive the inclined pressing plate 31 to swing around the rotation connection point of the inclined pressing plate 31 when the pushing and pressing frame 320 moves.

[0048] When the moving frame 42 moves, the pushing member 50 pushes the pushing and pressing frame 320 towards the inclined pressing plate 31. The pushing and pressing frame 320 cooperates with the guiding groove 322 through the traction shaft 321 to push the inclined pressing plate 31 towards the buckle 60 on the component 6 until the inclined pressing plate 31 rotates around its rotation connection point and abuts tightly against the buckle 60 on the component 6, thereby realizing the function of further fixing the component 6.

[0049] When the component 6 needs to be replaced, the pushing and pressing frame 320 moves in a direction away from the inclined pressing plate 31. The pushing and pressing frame 320 drives the inclined pressing plate 31 away from the buckle 60 of the component 6 through the sliding cooperation of the traction shaft 321 and the guiding groove 322, so as to facilitate the removal of the component 6.

[0050] Refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , the pushing member 50 includes an ear plate 501 and a pushing rod 502. Opposite surfaces of the upper and lower two pushing and pressing frames 320 are each provided with slots 503 symmetrically arranged along their length directions. Opposite surfaces of the two corresponding slots 503 in the horizontal direction are each provided with inclined slots 504. Guide grooves 505 communicating with the corresponding slots 503 are each provided on both the upper and lower sides of the sliding groove 40. The ear plate 501 is mounted on the moving frame 42, penetrates through the guide groove 505 and then penetrates into the slot 503. The pushing rod 502 is mounted on the ear plate 501 and is used to squeeze the inclined slot 504 to push the pushing and pressing frame 320 to move. A return spring 506 is mounted between the fixed bar 10 and the pushing and pressing frame 320.

[0051] During the movement of the moving frame 42, the ear plate 501 and the pushing rod 502 are driven to move. A ball is installed at the end of the pushing rod 502. When the ball at the end of the pushing rod 502 abuts against the inclined surface of the inclined groove 504, the pushing rod 502 drives the pushing frame 320 to move obliquely against the inclined plate 31 through the pushing inclined groove 504. A horizontal groove communicating with it is also provided on the inclined groove 504. When the inclined plate 31 abuts tightly against the buckle 60 on the component 6, the ball on the pushing rod 502 is in rolling contact with the horizontal groove until the pushing member 43 abuts tightly against the component 6.

[0052] Refer to Figure 2 And Figure 5 As shown in, the locking member 51 includes L-shaped plates 510 arranged symmetrically up and down at one end of the moving frame 42 away from the pushing member 43. A sleeve hole for sleeving the end of the pressing plate 210 is provided at the end of the L-shaped plate 510. The moving frame 42 drives the L-shaped plate 510 to move. The L-shaped plate 510 is sleeved on the end of the pressing plate 210 through the sleeve hole, thereby realizing the locking of the L-shaped plate 510.

[0053] Refer to Figure 1 - Figure 7 As shown in, the specific installation process: The component 6 is clamped on the upper and lower two card strips 11 through the buckle 60 installed thereon, and the wire 61 connected to the component 6 is clamped on the wire supporting component 20. When a plurality of components 6 and the wires 61 thereon are all limited, the pressing component 21 elastically presses and fixes the wire 61 on the wire supporting component 20, and then the pushing and locking part 4 is used to push the plurality of components 6 clamped on the card strips 11 to abut against each other tightly.

[0054] At the same time, the pushing and locking part 4 also drives the pushing component 32 through the linkage component 5 and locks the pressing component 21. Under the combined action of the pushing and locking part 4 and the linkage component 5, the pushing component 32 drives the inclined plate 31 to swing at the rotating joint and presses the buckle 60 clamped on the card strip 11 against the card strip 11 again, further improving the installation stability of the component 6. At the same time, the linkage component 5 also locks the pressing component 21, thereby improving the fixing and connection stability of the wire 61.
