Description

Technical Field

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

[0002] The installation structure of electrical components in the distribution cabinet is used to fix the electrical components to ensure the safe, reliable and efficient operation of the electrical system. 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 the guide rail, and modular components such as circuit breakers, contactors, PLCs, etc. are quickly fixed on the guide rail by snapping, without the need for drilling, making it easy to replace components.

[0004] However, the traditional guide rail installation structure relies solely on the elastic fixation of the guide rail clips. When encountering vibrations caused by adverse external factors (such as earthquakes, wind, and offshore platforms), it is easy to cause component displacement or poor contact, thereby affecting the installation stability of the electrical components and the long-term reliability of operation. In addition, the traditional installation structure only fixes the electrical components, but does not fix the wires connected to the electrical components. During long-term operation, the wires may vibrate, expand and contract with heat, causing the wires to loosen from the terminal blocks or component wiring ports (especially when the crimping is not firm or wire noses are not used), and the exposed wires may contact the cabinet or other conductors, easily causing a short circuit. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides an electrical component installation structure for a power distribution cabinet to solve the technical problems in the related art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the present invention provides the following technical solution: an electrical component installation structure for a distribution cabinet, comprising: a guide rail, a clamping locking portion, a pressing locking portion and a pushing locking portion, and a fixing frame is installed at both ends of the guide rail, and a waist-shaped groove is provided on the fixing frame to facilitate the guide rail to be connected to the distribution cabinet through the waist-shaped groove on the fixing frame.

[0007] The guide rail is composed of a fixing bar and a clamping bar which is installed on one side of the thickness direction and arranged symmetrically up and down. The clamping locking part, the pressing locking part and the pushing locking part are all installed on the fixing bar.

[0008] The clamp locking portion includes a wire clamping support assembly installed on both the upper and lower sides of the fixing bar and a pressure-pushing assembly arranged on the wire clamping support assembly; the pressure-pushing locking portion includes installation grooves opened on both the upper and lower sides of the fixing bar, an inclined pressure plate is rotatably connected to the installation groove, and a push assembly is also installed on the fixing bar.

[0009] The components are clamped on the upper and lower clamping strips through the clips installed on them, and the wires connected to the components are clamped on the wire clamping support assembly. After multiple components and the wires thereon are limited, the pressing assembly elastically presses the wires to fix them on the wire clamping support assembly, and then pushes the multiple components clamped on the clamping strips to press against each other by pushing the locking part.

[0010] At the same time, the pushing and locking part also drives the pushing assembly through the linkage assembly and locks the pressing assembly. Under the cooperation of the pushing and locking part and the linkage assembly, the pushing assembly drives the inclined plate to rotate and swing at the connection and presses the buckle on the card strip against the card strip again.

[0011] In one possible implementation, the wire-holding support assembly includes brackets symmetrically arranged along the length direction of the fixed bar, which are installed on the upper and lower sides of the fixed bar. A connecting shaft is installed between the two corresponding fixed bars in the horizontal direction, and a plurality of wire-holding parts evenly arranged along the axial direction are installed on the connecting shaft. The wire-holding parts are used to limit the wires on the components; the wire-holding parts are composed of a supporting wheel and an annular rubber clamping ring fixedly installed at both ends of its axial direction.

[0012] In one possible implementation, the pressure-resistance assembly includes a pressure plate that is slidably connected up and down between two corresponding brackets in the horizontal direction. The bracket is provided with a lifting guide groove that is slidably connected to the pressure plate. A return spring is installed between the lifting guide groove and the pressure plate. The pressure plate is parallel to the connecting axis. A pressure block corresponding to the wire clamping member is installed on the pressure plate, and an arc-shaped clamping groove is provided on the side of the pressure block close to the supporting wheel.

[0013] In one possible implementation, the pushing and locking portion includes two sliding grooves on the fixed bar and symmetrically arranged along its length direction. A rotating rod is rotatably connected between the two sliding grooves, and a movable frame is slidably connected to the sliding groove. The movable frame and the rotating rod are connected by threaded fitting, and the opposite surfaces of the two movable frames are fixedly installed with pushing parts that are slidably connected to the fixed bar.

[0014] In a possible implementation, the pushing member is composed of a fixed cylinder, a pressing seat slidably connected to the fixed cylinder, and a spring installed between the fixed cylinder and the pressing seat, and the fixed cylinder is fixedly connected to the movable frame.

[0015] In one possible implementation, the linkage assembly includes a pusher and a locking member installed on a movable frame. The pusher is used to push the push assembly toward the inclined support plate to drive the inclined support plate to press against the buckle, and the locking member is used to lock the position of the pressure plate pressed on the wire.

[0016] In one possible implementation, the push assembly includes a push frame connected to the upper and lower sides of the fixed bar, the push frame slides along the thickness direction of the fixed bar, and the push frame is rotatably connected to the side of the inclined push plate close to the inclined push plate. A guide groove is provided on the inclined push plate that runs through both ends of its length direction. The traction shaft slides into the guide groove, and the guide groove and the traction shaft slide in cooperation to drive the inclined push plate to swing around the rotating connection of the inclined push plate when the push frame moves.

[0017] In one possible implementation, the pushing member includes an ear plate and a push rod. The opposing surfaces of the upper and lower push frames are provided with slots symmetrically arranged along their length directions. The opposing surfaces of the two corresponding slots in the horizontal direction are provided with inclined grooves. The upper and lower sides of the slide groove are provided with guide grooves connected to the corresponding slots. The ear plate is installed on the movable frame and passes through the guide groove and then into the slot. The push rod is installed on the ear plate and is used to squeeze the inclined groove to push the push frame to move. A reset spring is installed between the fixed bar and the push frame.

[0018] In one possible implementation, the locking member includes an L-shaped plate that is symmetrically arranged up and down and installed at one end of the movable frame away from the pushing member. The end of the L-shaped plate is provided with a sleeve hole for being mounted on the end of the pressure plate. The movable frame drives the L-shaped plate to move, and the L-shaped plate is mounted on the end of the pressure plate through the sleeve hole, thereby locking the L-shaped plate.

[0019] The above one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: 1. The present invention designs an electrical component installation structure for a distribution cabinet, which cooperates with a pressing locking part and a pushing locking part to press and reinforce the buckles of the components connected to the guide rail again and press and reinforce the components against each other, preventing the components from sliding along the length direction of the guide rail under the action of vibration force. The stability of component installation and the reliability of operation are greatly improved under the action of multiple fixing forces, and the pushing locking part cooperates with the clamping locking part to support, fix and lock the wires, preventing the wires from shaking and detaching from the components under external factors, affecting the reliability of the direct connection between the components and the wires.

[0020] 2.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

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

[0034] See Figure 1 A distribution cabinet electrical component installation structure includes: a guide rail 1, a clamping locking part 2, a pressing locking part 3 and a pushing locking part 4. Both ends of the guide rail 1 are installed with a fixing frame, and a waist-shaped groove is opened on the fixing frame to facilitate the subsequent connection of the guide rail 1 with the distribution cabinet through the waist-shaped groove on the fixing frame.

[0035] See Figure 1 The guide rail 1 consists of a fixing bar 10 and a symmetrically arranged clip bar 11 installed on one side of its thickness direction. The clip locking part 2, the pressing locking part 3 and the pushing locking part 4 are all installed on the fixing bar 10.

[0036] See Figure 1 、 Figure 5 and Figure 6The clamp locking part 2 includes a wire clamping support assembly 20 installed on both the upper and lower sides of the fixing bar 10 and a pressing assembly 21 provided on the wire clamping support assembly 20; the pressing locking part 3 includes an installation groove 30 opened on both the upper and lower sides of the fixing bar 10, and an inclined pressing plate 31 is rotatably connected to the installation groove 30, and a pushing assembly 32 is also installed on the fixing bar 10.

[0037] The component 6 is clamped on the upper and lower clamping strips 11 through the buckle 60 installed thereon, and the wire 61 connected to the component 6 is clamped on the wire clamping support assembly 20. After multiple components 6 and the wires 61 thereon are limited, the pressing assembly 21 elastically presses the wire 61 to fix it on the wire clamping support assembly 20, and then pushes the locking part 4 to push the multiple components 6 clamped on the clamping strip 11 to press against each other, so as to prevent the component 6 from moving along the length direction of the guide rail 1 due to external factors, affecting the installation stability of the component 6.

[0038] See 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 plate 31 to rotate and swing at the connection under the cooperation of the pushing and locking part 4 and the linkage component 5, and presses the buckle 60 stuck on the card strip 11 against the card strip 11 again, further improving the stability of the installation of the component 6. At the same time, the linkage component 5 also locks the pressing component 21, thereby improving the stability of the fixation and connection of the wire 61.

[0039] See Figure 1 、 Figure 2 and Figure 3 The wire holding support assembly 20 includes brackets 201 symmetrically arranged along the length direction of the fixing bar 10, which are installed on the upper and lower sides of the fixing bar 10. A connecting shaft 202 is installed between the two corresponding fixing bars 10 in the horizontal direction. The connecting shaft 202 is equipped with multiple wire holding members 203 evenly arranged along its axial direction. The wire holding members 203 are used to limit the wire 61 on the component 6; the wire holding member 203 consists of a supporting wheel 221 and an annular rubber clamp 220 fixedly installed at both ends of its axial direction.

[0040] See Figure 1 、 Figure 2 and Figure 3 The pressure-resisting assembly 21 includes a pressure plate 210 that is slidably connected between two brackets 201 corresponding to each other in the horizontal direction. The bracket 201 is provided with a lifting guide groove 211 that is slidably connected to the pressure plate 210. A return spring 213 is installed between the lifting guide groove 211 and the pressure plate 210. The pressure plate 210 is parallel to the connecting shaft 202. A pressure block 214 corresponding to the wire clamping member 203 is installed on the pressure plate 210. An arc-shaped clamping groove is provided on the side of the pressure block 214 close to the supporting wheel 221.

[0041] After the component 6 is stuck on the guide rail 1, the pressure plate 210 is pulled to move away from the connecting shaft 202 so that the wire 61 can be stuck on the wire clamping member 203, and then the wire 61 on the component 6 is clamped between the annular rubber clamping rings 220 on both sides of the supporting wheel 221. The two annular rubber clamping rings 220 limit the wire 61 to prevent the wire 61 from moving around and affecting the installation of the component 6, while facilitating the installation and connection of the wire 61. After all the wires 61 are placed, the pressure plate 210 is released. Under the elastic force of the return spring 213, the pressure plate 210 drives the pressure block 214 to press against the wire 61. The pressure block 214 cooperates with the supporting wheel 221 to fix the wire 61.

[0042] See Figure 1 and Figure 2 The pushing and locking portion 4 includes two sliding grooves 40 symmetrically arranged along the length direction of the fixed bar 10, a rotating rod 41 is rotatably connected between the two sliding grooves 40, and a mobile frame 42 is slidably connected to the sliding groove 40. The mobile frame 42 is connected to the rotating rod 41 by threaded fitting, and the opposite surfaces of the two mobile frames 42 are fixedly installed with pushing members 43 slidably connected to the fixed bar 10.

[0043] See Figure 2 and Figure 4 The pushing member 43 is composed of a fixed cylinder 430, a pressing seat 431 slidably connected to the fixed cylinder 430, and a spring 432 installed between the fixed cylinder 430 and the pressing seat 431. The fixed cylinder 430 is fixedly connected to the movable frame 42.

[0044] When the components 6 and the wires 61 are all placed and fixed, the rotating rod 41 is rotated again. The rotating rod 41 drives the two moving frames 42 to move relative to each other through the threaded cooperation between the rotating rod 41 and the moving frame 42. During the movement, the moving frame 42 drives the pushing piece 43 to move toward the component 6, thereby pressing the multiple components 6 on the card strip 11 against each other, avoiding external factors that cause the component 6 to move along the length direction of the guide rail 1, affecting the installation stability of the component 6.

[0045] At the same time, a spring 432 between the fixing cylinder 430 and the pressing seat 431 ensures a certain elastic force between the fixing cylinder 430 and the pressing seat 431 to prevent the component 6 from being damaged when the component 6 is pressed tightly.

[0046] See Figure 2 、 Figure 5 and Figure 6The linkage assembly 5 includes a pusher 50 and a locking member 51 installed on the movable frame 42. The pusher 50 is used to push the push assembly 32 to move toward the inclined plate 31 to drive the inclined plate 31 to press against the buckle 60. The locking member 51 is used to lock the position of the pressure plate 210 pressed on the wire 61.

[0047] See Figure 2 、 Figure 5 and Figure 6 The pushing assembly 32 includes a pushing frame 320 connected to the upper and lower sides of the fixed bar 10. The pushing frame 320 slides along the thickness direction of the fixed bar 10. The pushing frame 320 is rotatably connected to the traction shaft 321 on the side close to the inclined support plate 31. The inclined support plate 31 is provided with a guide groove 322 running through both ends of its length direction. The traction shaft 321 slides into the guide groove 322. The guide groove 322 and the traction shaft 321 slide in cooperation. When the pushing frame 320 moves, it drives the inclined support plate 31 to swing around the rotating connection of the inclined support plate 31.

[0048] When the movable frame 42 moves, the pushing member 50 pushes the pushing frame 320 to move toward the inclined support plate 31. The pushing frame 320 cooperates with the guide groove 322 through the traction shaft 321 to push the inclined support plate 31 toward the buckle 60 on the element 6 until the inclined support plate 31 rotates around its rotation connection point and is tightly pressed against the buckle 60 on the element 6, thereby achieving the function of further fixing the element 6.

[0049] When the component 6 needs to be replaced, the push frame 320 moves away from the inclined support plate 31. The push frame 320 drives the inclined support plate 31 away from the buckle 60 of the component 6 through the sliding cooperation between the traction shaft 321 and the guide groove 322, so as to facilitate the removal of the component 6.

[0050] See Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The pushing member 50 includes an ear plate 501 and a push rod 502. The opposite surfaces of the upper and lower push frames 320 are provided with slots 503 arranged symmetrically along their length direction. The opposite surfaces of the two corresponding slots 503 in the horizontal direction are provided with inclined grooves 504. The upper and lower sides of the slide 40 are provided with guide grooves 505 connected to the corresponding slots 503. The ear plate 501 is installed on the movable frame 42 and passes through the guide groove 505 and then into the slot 503. The push rod 502 is installed on the ear plate 501 and is used to squeeze the inclined groove 504 to push the push frame 320 to move. A return spring 506 is installed between the fixed bar 10 and the push frame 320.

[0051] During the movement of the movable frame 42, the ear plate 501 and the push rod 502 are driven to move. A ball is installed at the end of the push rod 502. When the ball at the end of the push rod 502 collides with the inclined surface of the inclined groove 504, the push rod 502 drives the push frame 320 to move toward the inclined support plate 31 through the inclined groove 504. The inclined groove 504 is also provided with a horizontal groove connected to it. When the inclined support plate 31 is pressed against the buckle 60 on the component 6, the ball on the push rod 502 rolls in contact with the horizontal groove until the pushing member 43 is pressed against the component 6.

[0052] See Figure 2 and Figure 5 The locking member 51 includes an L-shaped plate 510 symmetrically arranged up and down and installed at one end of the movable frame 42 away from the pushing member 43. The end of the L-shaped plate 510 is provided with a sleeve hole for being mounted on the end of the pressure plate 210. The movable frame 42 drives the L-shaped plate 510 to move, and the L-shaped plate 510 is mounted on the end of the pressure plate 210 through the sleeve hole, thereby locking the L-shaped plate 510.

[0053] See Figure 1-Figure 7 The specific installation process is as follows: the component 6 is clamped on the upper and lower clamping strips 11 through the buckle 60 installed thereon, and the wire 61 connected to the component 6 is clamped on the wire clamping support assembly 20. After multiple components 6 and the wires 61 thereon are limited, the pressing assembly 21 elastically presses the wire 61 to fix it on the wire clamping support assembly 20, and then pushes the multiple components 6 clamped on the clamping strip 11 to press against each other by pushing the locking part 4.

[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 cooperation of the pushing and locking part 4 and the linkage component 5, the pushing component 32 drives the inclined plate 31 to rotate and swing at the connection and press the buckle 60 stuck on the card strip 11 against the card strip 11 again, further improving the stability of the installation of the component 6. At the same time, the linkage component 5 also locks the pressing component 21, thereby improving the stability of the fixation and connection of the wire 61.
