Description

Technical Field

[0001] The invention belongs to the technical field of busbars, and in particular relates to a busbar that is easy to disassemble. Background Art

[0002] A bus is a device that collects and distributes electric current, including a base and a busbar fixed in the base. The busbars on the bus are respectively connected to the power supply end and multiple load ends. After the power supply end supplies power, the bus will distribute the electricity to each load end.

[0003] During the long-term use of the bus, in order to reduce the possibility of sudden failure of the bus, it is necessary to regularly inspect the busbars in the bus and replace them when they are damaged. However, in the existing bus, the busbars are mostly fixed to the base through threaded fasteners or disposable fasteners. The former requires the complete removal of the threaded fasteners when the busbar is disassembled and installed, which is cumbersome. The latter is only easy to disassemble, and new fasteners need to be replaced when the busbar is reinstalled, which is still not convenient enough. Therefore, it is necessary to specifically design a busbar that is easy to disassemble the busbar Summary of the invention

[0004] Aiming at the problem that the existing busbars are complicated to disassemble and install, and it is inconvenient for operators to regularly inspect and maintain the busbars, the following invention is proposed:

[0005] A busbar that is easy to disassemble comprises a base, a busbar and an insulating plate. The base is provided with a plurality of fixing posts that penetrate the busbar and the insulating plate. The busbar is attached to the outer side of the base, and the insulating plate is attached to the outer side of the busbar. A fixing head is threadedly connected to the end of the fixing post. An annular clamping groove is provided between the fixing head and the fixing post. After the fixing head is screwed in and out toward the fixing post, the width of the clamping groove is changed. A fixing sleeve that is sleeved on the outer side of the clamping groove is attached to the outer side of the insulating plate. A sleeve hole for the fixing post to pass through is provided at the center of the fixing sleeve. An installation groove is provided on the fixing sleeve. An clamping plate and a button are provided in the installation groove. The clamping plate is elastically connected to the installation groove, and an clamping head inserted into the clamping groove is provided on the clamping plate to prevent the fixing sleeve from moving outward along the fixing head and separating from the insulating plate. The button is transmission-connected to the clamping plate. After the button is pressed, the clamping plate moves toward the side away from the sleeve hole and drives the clamping head to separate from the clamping groove, so that the fixing sleeve can move along the fixing post and separate from the insulating plate.

[0006] Since the fixing head can be screwed in and out, the engaging groove will change width after the fixing head is screwed in and out. The operator can screw the fixing head in until the engaging groove just fits perfectly with the engaging plate according to actual needs. At this time, the fixing sleeve will press against the outside of the insulating plate to prevent the insulating plate from being removed. After pressing the button, the engaging plate will be disengaged from the engaging groove, and the fixing sleeve can be removed and the insulating plate can be disassembled.

[0007] Furthermore, a driving head is provided on the engaging plate, and a driving block located on the top of the driving head is provided at the bottom of the button. Matching inclined surfaces are provided on the driving head and the driving block. After the button is pressed, the driving block moves and pushes the driving head toward the outside. After the driving head moves, the engaging plate moves toward the side away from the sleeve hole, so that the engaging head disengages from the engaging groove.

[0008] Furthermore, a plurality of baffles are provided in the installation groove, and engaging holes connected to the engaging groove are provided between the baffles. The engaging head passes through the engaging hole and is inserted into the engaging groove. An arc arm is provided between the engaging plate and the driving head, and the baffle is blocked on one side of the arc arm to prevent the engaging plate from detaching from the installation groove after moving.

[0009] Furthermore, a first annular groove is provided in the installation groove, a second annular groove is provided on the clamping plate, and springs for elastically connecting the installation groove and the clamping plate are inserted into the first annular groove and the second annular groove.

[0010] Furthermore, it also includes a cover plate, the installation groove is provided with a plurality of fixing pins, the cover plate is provided with a plurality of fixing holes, the fixing pins are inserted into the fixing holes to fix the connection between the mounting seat and the cover plate, and the cover plate covers the installation groove from the outside.

[0011] Furthermore, the installation groove and the cover plate are each provided with a plurality of sliding blocks, and the side of the engaging plate is provided with a plurality of sliding grooves movably matched with the sliding blocks to prevent the engaging plate from deflecting during movement.

[0012] Furthermore, a guiding inclined surface is provided on the engaging head, and when the fixing sleeve is sleeved on the fixing column, the end of the fixing column abuts against the guiding inclined surface to drive the engaging head to move toward a side away from the sleeve hole.

[0013] The present invention proposes a busbar that is easy to disassemble, and its beneficial effects are: (1) the traditional fixing part is replaced with an operable fixing sleeve, and a snap-fitting head is provided inside the fixing sleeve to snap-fit ​​with the snap-fitting groove between the fixing column and the fixing head. The snap-fitting head can be disengaged from the snap-fitting groove by pressing a button on the fixing sleeve. After that, the fixing sleeve is removed from the fixing head and the fixing column, and the insulating plate can be disassembled. During installation, it is only necessary to directly sleeve the fixing sleeve on the fixing column, which is relatively convenient; (2) the fixing head can be screwed in and out to adjust the width of the snap-fitting groove, so as to facilitate the coordinated installation of the snap-fitting head and the snap-fitting groove, thereby improving the stability of the fixing of the insulating plate.

[0027] like Figure 1 As shown, it is a preferred embodiment of the present invention, a busbar that is easy to disassemble, including a base 1, a busbar 2, and an insulating plate 12. A fixing column 3 and a groove 11 are provided on the base 1, and through holes for the fixing column 3 to pass through are provided on the busbar 2 and the insulating plate 12. The busbar 2 is fitted in the groove 11, and the insulating plate 12 is fitted on the outside of the busbar 2.

[0028] like Figure 1-Figure 4 As shown, a fixing sleeve 4 is provided on the outside of the insulating plate 12, and a sleeve hole 42 for the fixing column 3 to pass through is provided at the center of the fixing sleeve 4. An annular engaging groove 31 is provided on the fixing column 3. After the fixing column 3 passes through the sleeve hole 42, the engaging groove 31 is located on the inner side of the sleeve hole 42. A mounting groove 41 is also provided on the fixing sleeve 4, and a engaging plate 5 and a button 6 are provided in the mounting groove 41. The engaging plate 5 is elastically connected to the mounting groove 41, and a engaging head 51 inserted into the sleeve hole 42 is also provided thereon. The end of the engaging head 51 is in an arc shape matching the engaging groove 31. The button 6 is transmission-connected to the engaging plate 5. After the button 6 is pressed, the engaging plate 5 moves toward the mounting groove 41.

[0029] After the base 1, the busbar 2 and the insulating plate 12 are assembled and installed by the fixing column 3, the button 6 on the fixing sleeve 4 is pressed, the engaging plate 5 shrinks toward the installation groove 41, and drives the engaging head 51 to disengage from the sleeve hole 42, and then the fixing sleeve 4 can be sleeved on the fixing column 3. After the fixing sleeve 4 moves along the fixing column 3 until it contacts the insulating plate 12, the button 6 is released, and the engaging plate 5 is driven by elastic force to move out of the installation groove 41, and the engaging head 51 is inserted into the sleeve hole 42. Since the engaging groove 31 is located on the inner side of the sleeve hole 42 at this time, the engaging head 51 is also inserted and engaged in the engaging groove 31 to prevent the fixing sleeve 4 from moving horizontally along the fixing column 3 and disengaging from the insulating plate 12. The insulating plate 12 is resisted by the fixing sleeve 4 to fix the busbar 2. When the insulating plate 12 and the busbar 2 need to be removed, the button 6 is pressed and the locking plate 5 moves into the installation groove 41 until the locking head 51 is disengaged from the locking groove 31. At this time, the fixing sleeve 4 can be moved horizontally along the fixing column 3 until it is disengaged. After that, the insulating plate 12 and the busbar 2 can be removed in turn for inspection and maintenance.

[0030] The detailed structures of the engaging plate 5 and the button 6, and how to realize the movement of the engaging plate 5 after the button 6 is pressed, are further described in detail below. The engaging plate 5 is provided with arc-shaped arms 52 at both ends, the end of the fixed arm is provided with a driving head 53, the bottom of the button 6 is provided with a driving block 61 located at the top of the driving head 53, and the driving head 53 and the driving block 61 are provided with matching inclined surfaces. After the button 6 is pressed, the driving block 61 moves toward the driving head 53, and after the inclined surfaces of the two are matched, the driving block 61 resists and pushes the driving head 53 to move elastically in the direction away from the sleeve hole 42, and the driving head 53 moves to drive the engaging plate 5 to move, and the engaging plate 5 moves to drive the engaging head 51 to separate from the sleeve hole 42 and the engaging groove 31.

[0031] Furthermore, a plurality of baffles 48 are provided in the mounting groove 41. The baffles 48 are arc-shaped toward the inner side of the mounting groove 41 and match the arc-shaped arm 52. A snap-fitting hole 47 connected to the sleeve hole 42 and the snap-fitting groove 31 is provided between the baffles 48. The snap-fitting head 51 passes through the snap-fitting hole 47 and is inserted into the snap-fitting groove 31. During the horizontal movement of the snap-fitting plate 5, the baffles 48 are always blocked on one side of the arc-shaped arm 52 to prevent the snap-fitting plate 5 from detaching from the mounting groove 41 after movement.

[0032] Furthermore, if Figure 4-Figure 5 As shown, a first annular groove 44 is further provided in the installation groove 41, and a second annular groove 54 is further provided on the engaging plate 5. A spring 43 which elastically connects the installation groove 41 and the engaging plate 5 is inserted into the first annular groove 44 and the second annular groove 54. When the button 6 is pressed, the engaging plate 5 moves horizontally toward the inside of the installation groove 41, and the spring 43 elastically contracts. When the button 6 is released, the engaging plate 5 is elastically driven by the spring 43 to reset. During the resetting process of the engaging plate 5, the driving head 53 abuts against the driving block 61, and drives the button 6 to reset together.

[0033] In this embodiment, if Figure 6 As shown, it also includes a cover plate 7 that covers the opening of the mounting groove 41 from the outside, a plurality of fixing pins 45 are provided in the mounting groove 41, and a plurality of fixing holes 71 are provided on the cover plate 7. The fixing pins 45 are inserted into the fixing holes 71 to fix the mounting seat and the cover plate 7. The locking plate 5, the spring 43, and the button 6 are all fixed in the mounting groove 41. In particular, if there is no need to separate the cover plate 7 and the fixing sleeve 4, a fixing method such as sealant can be used to fix the cover plate 7 and the fixing sleeve 4.

[0034] On the basis of the above, a plurality of sliders 46 are respectively provided on the installation groove 41 and the cover plate 7, and a plurality of slide grooves 56 are respectively provided on the front and rear sides of the locking plate 5. The slide grooves 56 are movably matched with the sliders 46 one by one. When the locking plate 5 moves in the installation groove 41, the slide grooves 56 move along the sliders 46 to ensure that the locking plate 5 will not be offset during the movement.

[0035] When the engaging groove 31 is pre-set on the side of the fixing column 3, the overall width cannot be adjusted. When in use, the engaging head 51 must be perfectly engaged in the engaging groove 31, otherwise a gap will appear between the insulating plate 12 and the fixing sleeve 4, affecting the stability of the installation of the insulating plate 12. To solve this problem, in the present embodiment, a threaded hole is provided at the end of the fixing column 3, and a fixing head 32 is threadedly connected in the threaded hole. The engaging groove 31 is provided between the fixing column 3 and the fixing head 32. After the fixing head 32 is screwed in and out toward the fixing column 3, the width of the engaging groove 31 can be changed.

[0036] During installation, first connect the fixing head 32 to the fixing column 3, and then sleeve the fixing sleeve 4 on the fixing column 3, the engaging head 51 is inserted into the engaging groove 31, and the fixing head 32 is screwed in to adjust the width of the engaging groove 31 to match the engaging head 51. At this time, the fixing sleeve 4 is in contact with the outside of the insulating plate 12, and the fixing head 32 is partially inserted into the sleeve hole 42 and in contact with the outside of the engaging head 51; when the fixing sleeve 4 needs to be removed from the fixing column 3 or installed again later, refer to the operating steps when the fixing head 32 is not set. According to the matching condition of the engaging groove 31 and the engaging head 51, it may be necessary to slightly rotate the fixing head 32 a distance beyond the outside before pressing the button 6.

[0037] Furthermore, a guiding bevel 55 is provided on the engaging head 51. When the fixing sleeve 4 is sleeved on the fixing column 3, the end of the fixing column 3 or the fixing head 32 abuts against the guiding bevel 55 to drive the engaging head 51 to move into the installation groove 41 and disengage from the sleeve hole 42. That is, when the fixing sleeve 4 is installed on the fixing column 3, there is no need to press the button 6.

[0038] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
