DETAILED DESCRIPTION

[0031] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0032] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "first," "second," etc. may refer to different or identical objects.

[0033] As described above, a bus duct assembly consists of at least two bus ducts and a bus duct connector. Bus ducts are typically manufactured in sections and assembled on-site using the bus duct connectors. Bus ducts used for high-current applications are typically wide and heavy. Relying solely on manual labor to move and position the bus ducts and bus duct connectors and connect them together is a time-consuming and labor-intensive process that can be difficult to achieve satisfactory results.

[0034] Related technologies use bus duct installation tools to improve the docking and installation of bus duct assemblies. These tools utilize a lever to push two bus ducts together, gradually inserting the phase conductors of each bus duct into the bus duct connector. However, during the docking process, it is difficult to determine whether the bus duct and bus duct connector are properly docked.

[0035] The embodiment of the present disclosure provides a bus duct assembly installation tool 100, which can not only save time and effort to connect the bus duct 60 and the bus duct connector 70 together, but also facilitates to quickly determine whether each bus duct 60 and the bus duct connector 70 are connected in place. Figures 1 to 11 The principles of the present disclosure are described.

[0036] Figure 1 A perspective view of an installation tool 100 for a bus duct assembly according to an embodiment of the present disclosure is shown. Figure 2 A perspective view of a bus duct 60 according to an embodiment of the present disclosure is shown. Figure 3 Shown Figure 1 An exploded view of a bus duct assembly installation tool 100 is shown. Figures 4 to 11 Shows the use of Figure 1 The installation tool 100 of the bus duct assembly is used to connect the bus duct connector 70 and two bus ducts 60 of the bus duct assembly together. Figures 8 to 10 As shown, the bus duct assembly includes two bus ducts 60 arranged left and right and a bus duct connector 70 located between the two bus ducts 60 .

[0037] See also Figure 1 The installation tool 100 of the bus duct assembly (hereinafter referred to as the installation tool 100 ) includes two auxiliary positioning devices 10 , a pull rod 20 and a driving rod 30 .

[0038] See also Figure 1 、 Figure 2 and Figure 8 , the two auxiliary positioning devices 10 are used to be installed respectively to two adjacent bus ducts 60. Each auxiliary positioning device 10 is installed, for example, on the cover plate 61 of the corresponding bus duct 60. In some embodiments, the connection position of each auxiliary positioning device 10 and the cover plate 61 roughly corresponds to the middle position of the cover plate 61. Each auxiliary positioning device 10 has a first limiting surface 121 for abutting against the end cover 71 of the bus duct connector 70. In the illustrated embodiment, the two auxiliary positioning devices 10 have the same structure, and the two auxiliary positioning devices 10 can be installed roughly symmetrically on two adjacent bus ducts 60. In some embodiments not shown, the structures of the two auxiliary positioning devices 10 may not be exactly the same.

[0039] See also Figure 1 and Figure 3, the first end 21 of the pull rod 20 is used to connect with the auxiliary positioning device 10 installed on one bus duct 60. In the illustrated embodiment, the first end 21 of the pull rod 20 is detachably hooked with the corresponding auxiliary positioning device 10. In some alternative embodiments, the first end 21 of the pull rod 20 can be connected to the corresponding auxiliary positioning device 10 in other ways, such as a pivot connection. When the first end 21 of the pull rod 20 is connected to the corresponding auxiliary positioning device 10, the second end 22 of the pull rod 20 can extend in the direction of the auxiliary positioning device 10 installed on another bus duct 60. The pull rod 20 includes at least one through hole 220.

[0040] In some embodiments, the pull rod 20 includes a plurality of through holes 220 spaced apart along the length of the pull rod 20. In some alternative embodiments not shown, the pull rod 20 may be provided with a single elongated through hole 220, and the elongated through hole 220 may be provided with at least one protrusion, which can divide the elongated through hole 220 into a plurality of areas and can withstand the pressure from the driving rod 30.

[0041] See also Figure 1 The driving rod 30 selectively passes through one of the plurality of through holes 220 (or a region of the elongated through hole 220). The first end 31 of the driving rod 30 abuts against the auxiliary positioning device 10 installed on another bus duct 60 (see Figure 8 When the second end 32 of the driving rod 30 is subjected to a first external force, the driving rod 30 rotates about its contact point with the pull rod 20. According to the lever principle, the two bus ducts 60 are pushed closer to each other by the driving rod 30 and the pull rod 20, thereby connecting the bus duct connector 70 and the two bus ducts 60 together.

[0042] When the installation tool 100 provided by the embodiment of the present disclosure is used for installing a bus duct assembly, an auxiliary positioning device 10 can be first installed on a bus duct 60 (see Figure 8 and Figure 9), and then dock the bus duct connector 70 with the one bus duct 60. During the docking process of the bus duct connector 70 with the one bus duct 60, the installer can quickly determine that the bus duct connector 70 and the one bus duct 60 have been docked in place by the abutment between the end cover 71 of the bus duct connector 70 and the first limiting surface 121 of the auxiliary positioning device 10 installed on the one bus duct 60. Then install another auxiliary positioning device 10 on the other bus duct 60 (of course, in some embodiments, the two auxiliary positioning devices 10 can be first installed on the corresponding bus duct 60 respectively, and then the bus duct connector 70 and any bus duct 60 are docked together). Afterwards, hook the first end 21 of the pull rod 20 with any auxiliary positioning device 10, and then selectively pass the first end 31 of the drive rod 30 through a through hole 220 and abut against the other auxiliary positioning device 10. Then, a first external force is applied to the second end 32 of the driving rod 30. Under the action of the lever, the installer can pull the two bus duct connectors 70 together in a time-saving and labor-saving manner. At the same time, the first limiting surfaces 121 of the two auxiliary positioning devices 10 approach each other, and the phase conductor 63 of the other bus duct gradually extends into the bus duct connector 70.

[0043] In the process of applying the first external force to the driving rod 30 to pull the two bus ducts 60 closer, according to the change in the distance between the two bus ducts 60, the first end 31 of the driving rod 30 is appropriately adjusted to be inserted into different through holes 220 until the end cover 71 of the bus duct connector 70 is clamped between the first limiting surfaces 121 of the two auxiliary positioning devices 10 (see Figure 10 At this time, under the positioning effect of the two first limiting surfaces 121, even if the installer continues to apply the first external force to the second end 32 of the driving rod 30, the two bus ducts 60 cannot be pushed closer to each other. The installer can thus quickly determine that the entire bus duct assembly is docked in place.

[0044] Of course, in some alternative embodiments, the bus duct connector 70 may not be pre-installed on one bus duct 60. Instead, the bus duct connector 70 may be placed between two bus duct connectors 70, and then the driving rod 30 may be operated to gradually extend the phase conductors 63 of both bus ducts 60 into the bus duct connector 70. Similarly, when the end cap 71 of the bus duct connector 70 is clamped between the first limiting surfaces 121 of the two auxiliary positioning devices 10, the driving rod 30 cannot further push the two bus ducts 60 closer together, allowing the installer to quickly determine that the entire bus duct assembly is properly docked.

[0045] The following combination Figure 2 To illustrate the bus duct 60 according to an embodiment of the present disclosure, and Figure 7 and Figure 10The bus duct connector 70 according to one embodiment of the present disclosure is described below. A bus duct assembly including the bus duct connector 70 and two bus ducts 60 can be docked and installed using the installation tool 100 provided in an embodiment of the present disclosure.

[0046] The shell of the bus duct 60 includes two side panels 62 arranged opposite to each other and two cover plates 61 connected between the side panels 62. The two cover plates 61 are arranged opposite to each other, and the middle parts 611 of the two cover plates 61 and the side panels 62 on both sides form a accommodating cavity 610. Each cover plate 61 is recessed relative to the side panels 62 on both sides to form a groove-shaped space 620 adjacent to the accommodating cavity 610. The middle part 611 of the cover plate 61 can also be fixed with a U-shaped reinforcement rib 64, and the U-shaped reinforcement rib 64 is located in the groove-shaped space 620. In some embodiments, the U-shaped reinforcement rib 64 can be used to connect with the auxiliary positioning device 10.

[0047] The bus duct 60 includes phase conductor groups 63 disposed within the accommodating cavity 610. Each phase conductor group 63 includes a plurality of phase conductors 631. The phase conductor groups 63 extend through the accommodating cavity 610 along the longitudinal direction L of the bus duct 60. The ends of the phase conductor groups 63 extend beyond the ends of the side panels 62 in the longitudinal direction L. The ends 612 of the cover plate 61 also extend beyond the side panels 62 in the longitudinal direction L to cover the ends of the phase conductor groups 63.

[0048] The bus duct 60 may be a single-row bus duct or a multi-row bus duct depending on the number of phase conductor groups 63. When the number of phase conductor groups 63 is not less than two, the phase conductor groups 63 are spaced apart along the width direction W of the bus duct 60. Figure 2 Taking two phase conductor groups 63 as an example, the bus duct 60 can be referred to as a double-row bus duct. The two phase conductor groups 63 are spaced apart in the width direction W. Of course, the bus duct 60 is not limited to a double-row bus duct. In some embodiments not shown, the bus duct 60 can be a single-row bus duct, a three-row bus duct, or other configurations.

[0049] The bus duct connector 70 includes two cover plates 71 arranged opposite to each other, a plurality of partition plates 72 located between the two cover plates 71, and fasteners 73 for fastening the two cover plates 71 and the plurality of partition plates 72 together. The plurality of partition plates 72 are arranged at intervals to form gaps (not numbered in the figure) for the respective phase conductors 631 of the bus duct 60 to be inserted. Conductors (not shown in the figure) are provided on the partition plates 72, and the corresponding phase conductors 631 of the two bus ducts 60 are electrically connected through the conductors on the partition plates 72. In addition, a gap is formed between each cover plate 71 and the adjacent partition plates 72 for the end of the cover plate 61 to be inserted. Each cover plate 71 includes a main body 711 and flanges 712 located on both sides of the main body 711. Each flange 712 extends outward from the edge of the main body 711.

[0050] See also Figure 10 When the bus duct components are docked, under the influence of the trumpet-shaped end structure of the phase conductor group 63 of the bus duct 60, the side panels 62 on both sides of the bus duct 60 and the cover plate 71 of the bus duct connector 70 are spaced apart in the longitudinal direction L of the bus duct 60.

[0051] See also Figure 9 and Figure 10 It can be understood that each first limiting surface 121 extends beyond the end 621 of the side panels 62 of the corresponding bus duct 60 in the longitudinal direction L so as to be able to abut against the cover 71 of the bus duct connector 70, thereby clamping the end cover 71 of the bus duct connector 70 between the first limiting surfaces 121 of the two auxiliary positioning devices 10. It can be understood that the first limiting surface 121 can extend a long distance in the width direction W of the bus duct 60 to provide sufficient span support for the cover 71 of the bus duct connector 70 in the width direction W, thereby preventing the bus duct connector 70 and the two bus ducts 60 from deflecting relative to each other when they are docked and continue to be pushed by the driving rod 30.

[0052] It should be noted that, unless otherwise specified, directional terms such as "the longitudinal direction of the bus duct 60," "longitudinal direction," and "the longitudinal direction of the bus duct assembly" in the embodiments of the present disclosure refer to the direction indicated by arrow L in the accompanying drawings, and directional terms such as "the width direction of the bus duct 60," "the width direction," and "the width direction of the bus duct assembly" refer to the direction indicated by arrow W in the accompanying drawings. These directional terms are used solely to clarify the description of the embodiments of the present disclosure and are not intended to improperly limit the scope of protection of the present disclosure.

[0053] In the embodiment of the present disclosure, the installation tool 100 utilizes a lever to dock the bus duct assemblies together, making the docking installation of the bus duct assemblies time-saving and labor-saving. By having the first limiting surfaces 121 of the two auxiliary positioning devices 10 clamp the cover plate 71 of the bus duct connector 70, the two bus ducts 60 are prevented from moving closer after being docked with the bus duct connector 70, making it easier for the installer to determine whether the bus duct assemblies are docked. It is understood that the installation tool 100 provided in the embodiment of the present disclosure can also use the lever principle to conveniently disassemble docked bus duct assemblies.

[0054] See also Figure 1 and Figure 3 The embodiment of the present disclosure shows an exemplary implementation of the auxiliary positioning device 10. Specifically, the auxiliary positioning device 10 includes an auxiliary member 11 and a positioning member 12.

[0055] See also Figure 4 and Figure 5The auxiliary member 11 is used to be detachably connected to the bus duct 60 (more specifically, the U-shaped reinforcement rib 64 of the cover plate 61), and the positioning member 12 is connected to the auxiliary member 11. In this way, the auxiliary positioning device 10 can be installed on the bus duct 60 or removed from the bus duct 60 as needed.

[0056] See again Figure 2 and Figure 3 The disclosed embodiment shows an exemplary structure of the auxiliary component 11 and an exemplary detachable connection method between the auxiliary component 11 and the bus duct 60. Specifically, the auxiliary component 11 includes a connecting portion 114, which is used to detachably engage with the bus duct 60. More specifically, the connecting portion 114 detachably engages with the corresponding fixing groove 640 on the bus duct 60.

[0057] See also Figure 3 In some embodiments, the auxiliary component 11 has a hollow block structure, including a top wall 113, a second side wall 112 extending downward from the top wall 113, and two first side walls 111. The two first side walls 111 are opposite to each other, and the second side wall 112 is located between the two first side walls 111. The top wall 113 is provided with a socket 1130 for inserting the first end 31 of the driving rod 30. The first end 31 of the driving rod 30 is inserted into the socket 1130 to abut against the auxiliary positioning device 10. The socket 1130 facilitates positioning the abutment position of the first end 31 of the driving rod 30 and the auxiliary positioning device 10, providing a reliable lever fulcrum for the driving rod 30. The connecting portion 114 is provided on the two first side walls 111. The second side wall 112 is provided with a snap-in groove 1121, which is used to cooperate with the first end 21 of the pull rod 20. Of course, the structure of the auxiliary component 11 is not limited to this.

[0058] See again Figure 2 In some embodiments, the cover plate 61 of the bus duct 60 includes two vertical walls 641 arranged opposite to each other, and the two vertical walls 641 are formed by, for example, U-shaped reinforcement ribs 64 fixed to the cover plate 61. The U-shaped reinforcement ribs 64 are fixed to the cover plate 61 by, for example, fasteners 65. The U-shaped reinforcement ribs 64 extend along the longitudinal direction L in the middle part 611 of the cover plate 61, and the two vertical walls 641 extend along the longitudinal direction L of the bus duct 60 accordingly. The two vertical walls 641 are spaced apart in the width direction W of the bus duct 60. Each vertical wall 641 includes at least one fixing groove 640, and the at least one fixing groove 640 is used to be detachably engaged with the connecting portion 114 of the auxiliary component 11.

[0059] In some embodiments, each fixing groove 640 includes a first groove portion 6401 and a second groove portion 6402. The first groove portion 6401 extends downward from the top of the vertical wall 641, and the second groove portion 6402 extends from the bottom of the first groove portion 6401 along the longitudinal direction L toward the adjacent end of the bus duct 60. The connecting portion 114 includes at least two ribs 1141, and the at least two ribs 1141 extend from the bottom of the two first side walls 111 in opposite directions in the width direction W. Each rib 1141 can be snap-fitted with the corresponding fixing groove 640. Figure 2 and Figure 3 In the illustrated embodiment, each vertical wall 641 is provided with two fixing grooves 640 , which are spaced apart in the longitudinal direction L. Two ribs 1141 are spaced apart at the bottom of each first side wall 111 , and the number of the ribs 1141 corresponds to the number of the fixing grooves 640 .

[0060] See also Figure 4 and Figure 5 The process of connecting the auxiliary component 11 to the bus duct 60 is shown. First, align the ribs 1141 of the connecting portion 114 with the first groove portion 6401 of the corresponding fixing groove 640, and then insert the ribs 1141 into the corresponding first groove portion 6401. After the ribs 1141 are inserted into the bottom of the corresponding first groove portion 6401, they are then moved in the corresponding second groove portion 6402 along the first direction L1 parallel to the longitudinal direction L until they move to the end of the second groove portion 6402 away from the first groove portion 6401, so that the auxiliary component 11 and the bus duct 60 are connected in place. That is, the auxiliary component 11 can move in the first direction L1 relative to the bus duct 60 so that the connecting portion 114 is connected to the bus duct 60. At this time, the movement of the auxiliary component 11 relative to the bus duct 60 in the first direction L1 is restricted. As will be described below, after the auxiliary member 11 is snapped into place with the bus duct 60, the movement of the auxiliary member 11 relative to the bus duct 60 in the second direction L2 can be limited by the positioning member 12. The second direction L2 is opposite to the first direction L1.

[0061] In some embodiments, the auxiliary member 11 may be located between two vertical walls 641, and the two vertical walls 641 limit the movement of the auxiliary member 11 relative to the bus duct 60 in the width direction W. In some alternative embodiments, the movement of the auxiliary member 11 relative to the bus duct 60 in the width direction W may be limited by other suitable structures, and the present disclosure is not limited in this regard.

[0062] Furthermore, in some alternative embodiments, the number of ribs 1141 and fixing grooves 640 can be increased as needed. For example, the bottom of each first sidewall 111 can be provided with one or more ribs 1141. It will be appreciated that a greater number of ribs 1141 and fixing grooves 640 results in a more secure engagement between the auxiliary component 11 and the bus duct 60. In some alternative embodiments, the structure of the connecting portion 114 is not limited to ribs 1141; the connecting portion 114 can be adapted as long as it can move along the first direction T1 to engage with the bus duct 60.

[0063] Combined with reference Figure 3 、 Figure 5 and Figure 6 The embodiment of the present disclosure shows an exemplary structure of the positioning member 12 and an exemplary connection method between the positioning member 12 and the auxiliary member 11.

[0064] In the embodiment of the present disclosure, the positioning member 12 is specifically pivotally connected to the auxiliary member 11 via a pivot 125, and the center line of the pivot 125 forms the pivot axis XX of the positioning member 12 (see FIG. Figure 6 The pivot axis XX is substantially perpendicular to the longitudinal direction L of the bus duct 60 and substantially parallel to the width direction W of the bus duct 60. The positioning member 12 can rotate around the pivot axis XX in the direction T1 approaching the bus duct 60 (more specifically, the end cover 61 of the bus duct 60) to Figure 6 The working position shown in FIG. 1 and the working position shown in FIG. 2 can be rotated about the pivot axis XX in the direction T2 away from the bus duct 60 to Figure 5 That is, the positioning member 12 can be rotated between the working position and the avoidance position.

[0065] The first limiting surface 121 is formed on the positioning member 12. Figure 9 and Figure 10 When the positioning member 12 is in the working position, the auxiliary positioning device 10 is positioned on the bus duct 60 in the longitudinal direction L, and the first limiting surface 121 is suitable for abutting against the flanges 712 on both sides of the end cover 71 of the bus duct connector 70 to clamp the end cover 71 of the bus duct connector 70. In combination with the above, it can be seen that when the positioning member 12 is in the working position, the first limiting surface 121 exceeds the side plate 62 in the longitudinal direction L. Specifically, see Figure 8 The longitudinal distance between the first limiting surface 121 and the pivot axis XX is D1, and the longitudinal distance between the end 621 of the two side plates 62 of the bus duct 60 (adjacent to the positioning member 12) and the pivot axis XX is D2, and the longitudinal distance D1 is greater than the longitudinal distance D2.

[0066] See also Figures 9 to 11The first limiting surface 121 is provided with at least two open slots 123, and the positioning member 12 can also move along the pivot axis XX relative to the auxiliary member 11 under the action of a second external force. When the positioning member 12 is in the working position and abuts the flanges 712 on both sides of the end cover 71, the positioning member 12 is moved along the pivot axis XX, so that the at least two open slots 123 selectively face the flanges 712 on both sides of the end cover 71. The end cover 71 no longer interferes with the rotation of the positioning member 12 from the working position to the avoidance position, thereby facilitating the removal of the auxiliary positioning device 10 from the bus duct 10.

[0067] The positioning member 12 may further include a second limiting surface 122. Figure 6 When the positioning member 12 is in the working position, the second limiting surface 122 is adapted to be engaged with the end portions 621 of the corresponding side plates 62 of the bus duct 60. Figure 9 and Figure 10 When the bus duct assembly is docked in place but the driving rod 30 is still applying a force to move the two bus ducts 60 closer together, the pressure exerted on the positioning member 12 by the end cover 71 can be transmitted to the side panels 62 on both sides through the engagement between the second limiting surface 122 and the end portions 621 of the side panels 62 on both sides, which helps to avoid excessive deformation of the positioning member 12. In addition, through the engagement between the second limiting surface 122 and the end portions 621, the movement of the auxiliary member 11 relative to the bus duct 60 in the second direction L2 can also be limited, so that the auxiliary positioning device 10 is positioned on the bus duct 60 in the longitudinal direction L. Of course, in some alternative embodiments, the movement of the auxiliary member 11 relative to the bus duct 60 in the second direction L2 can also be limited by other structures and not limited to the methods in the embodiments of the present disclosure. In combination with the foregoing, it can be seen that when the positioning member 12 is in the avoidance position, it does not interfere with the engagement and disassembly of the auxiliary member 11 and the bus duct 60.

[0068] In some embodiments, a rotation limiting structure 40 is provided between the auxiliary member 11 and the positioning member 12. When the positioning member 12 rotates to the working position, the rotation limiting structure 40 limits the positioning member 12 from further rotation, and easily positions the positioning member 12 in the working position.

[0069] There are many ways to implement the rotation limiting structure 40. Figure 6 In the illustrated embodiment, the rotation limiting structure 40 specifically includes a connecting ear 124 and a limiting shaft 127. The connecting ear 124 is provided on the positioning member 12, and the limiting shaft 127 is provided on the auxiliary member 11. The positioning member 12 is pivotally connected to the pivot 125 via the connecting ear 124, and further pivotally connected to the auxiliary member 11. The limiting shaft 127 is substantially parallel to the pivot 125. When the positioning member 12 is rotated to the working position, the side 1241 of the connecting ear 124 abuts against the limiting shaft 127, preventing the positioning member 12 from continuing to rotate in the original direction. Of course, in other embodiments, the rotation limiting structure 40 may also have other implementations and is not limited to the above examples.

[0070] The following combination Figures 9 to 11 The working principle of the positioning member 12 will be described below.

[0071] See also Figure 9 and Figure 10 The positioning members 12 are in the working position, and the first limiting surfaces 121 of the two positioning members 12 respectively abut against the opposite ends of the flanges 712 on both sides of the end cover 71 (at this time, the opening grooves 123 are staggered with the flanges 712), clamping the end cover 71 between the first limiting surfaces 121, and the bus duct connector 70 and the two bus ducts 60 are docked in place. At this time, the abutment between the first limiting surfaces 121 and the flanges 712 on both sides can, on the one hand, provide sufficient span support for the end cover 71 in the width direction W, and on the other hand, limit the rotation of the positioning members 12 in the direction T2.

[0072] See also Figure 9 and Figure 11 When the positioning member 12 needs to be removed, a second external force is applied to the positioning member 12, causing it to move along the pivot axis XX until the two openings 123 on the first limiting surface 121 are aligned with the flanges 712 on either side of the end cap 71. At this point, the flanges 712 no longer interfere with the rotation of the positioning member 12 in the direction T2, allowing the positioning member 12 to easily flip upward in the direction T2 to leave the working position.

[0073] It is understood that when the number of opening slots 123 provided on the first limiting surface 121 is more than one pair, different pairs of opening slots 123 can match the end caps 71 of bus duct connectors 70 of different sizes. In this way, the installation tool 100 can be used for docking bus duct assemblies of different sizes (especially width).

[0074] See again Figure 3 and Figure 4 The present disclosure shows an exemplary structure of a positioning member 12. The positioning member 12 includes an L-shaped first portion 1201 and an L-shaped second portion 1202. The first portion 1201 is pivotally connected to the auxiliary member 11. The first limiting surface 121 and the second limiting surface 122 are located on the second portion 1202.

[0075] Specifically, the first portion 1201 extends along the width direction W of the bus duct 60, and the extension length W1 of the first portion 1201 is less than the distance W3 between the side plates 62 on both sides of the bus duct 60. Figure 6When the positioning member 12 is in the working position, the first portion 1201 is substantially located within the slot-shaped space 620 of the bus duct 60. The first portion 1201 specifically includes a first plate 12011 and a second plate 12012 extending from a side edge of the first plate 12011. When the positioning member 12 is in the working position, the first plate 12011 is substantially perpendicular to the cover plate 61, and the second plate 12012 extends from the upper edge of the first plate 12011.

[0076] A notch 1204 is provided in the middle position of the first part 1201, and two connecting ears 124 mentioned above are provided at two opposite edges of the notch 1204. The two connecting ears 124 specifically extend from the first plate 12011. A portion of the auxiliary part 11 is located between the two connecting ears 124, and the distance between the two connecting ears 124 limits the axial movement stroke of the positioning member 12 relative to the auxiliary part 11 on the pivot axis XX. Of course, in some alternative embodiments, other forms of axial limiting mechanisms can also be used to limit the axial movement stroke of the positioning member 12 relative to the auxiliary part 11. In addition, when the positioning member 12 rotates along the direction T2, the edge of the notch 1204 can abut against the auxiliary part 11, limiting the positioning member 12 to Figure 5 Of course, in some alternative embodiments, the positioning member 12 can be restricted to the avoidance position by other forms of limiting structures.

[0077] The second portion 1202 extends along the width direction W of the bus duct 60, and the extension length W2 of the second portion 1202 is not less than the distance W3 between the side plates 62 of the bus duct 60. The second portion 1202 is located outside the trough-shaped space 620. The second portion 1202 specifically includes a third plate 12021 and a fourth plate 12022. The third plate 12021 is opposite the first plate 12011, and the fourth plate 12022 extends from a side edge of the third plate 12021 and docks with the second plate 12012. When the positioning member 12 is in the working position, the third plate 12021 is substantially perpendicular to the cover plate 61, and the fourth plate 12022 extends from the upper edge of the first plate 12011. The first limiting surface 121 is formed on the third plate 12021, and the second limiting surface 122 is formed on the fourth plate 12022.

[0078] In some embodiments, the first portion 1201 and the second portion 1202 of the positioning member 12 can be integrally formed. Of course, in some alternative embodiments, the positioning member 12 can also have other implementations and is not limited to the above examples.

[0079] In addition, it should be noted that the auxiliary positioning device 10 can also have other implementations and is not limited to the above examples. As long as the auxiliary positioning device 10 can be installed on the corresponding bus duct 60, it can cooperate with the pull rod 20 and the drive rod 30 to dock the bus duct assembly (i.e., the bus duct connector 70 and the two bus ducts 60) together, and the first limiting surface 121 is used to locate the docking position of the bus duct connector 70 and the two bus ducts 60. For example, in some alternative embodiments, the auxiliary part 11 is fixed to the bus duct 60, and the positioning part 12 is detachably connected to the auxiliary part 11. In some alternative embodiments, the auxiliary positioning device 10 is, for example, an integrally formed part, and is detachably connected to the bus duct 60 by fasteners.

[0080] See again Figure 3 and Figure 8 In some embodiments, a hook portion 211 is formed at the first end 21 of the pull rod 20, and the pull rod 20 is detachably hooked with the corresponding auxiliary component 11 through the hook portion 211. More specifically, the second side wall 112 of the auxiliary component 11 is provided with a snap-in groove 1121, and the hook portion 211 includes a step portion 2111 that can abut against the outer surface of the second side wall 112 and a protrusion 2112 protruding from the step portion 2111, and the protrusion 2112 is used to snap into the snap-in groove 1121. The snap-in connection between the snap-in groove 1121 and the protrusion 2112 positions the hooking position of the hook portion 211 and the auxiliary component 11, thereby preventing the hook portion 211 from slipping during the hooking process with the auxiliary component 11. The step portion 2111 can increase the contact area between the hook portion 211 and the second side wall 112, thereby avoiding excessive stress concentration.

[0081] In some embodiments, one, two, or more engaging grooves 1121 may be provided on the second side wall 112. Correspondingly, one, two, or more hooks 211 may be provided on the first end 21 of the pull rod 20.

[0082] The following combination Figures 4 to 11 To illustrate an example process of docking a bus duct assembly using the installation tool 100 according to an embodiment of the present disclosure.

[0083] Install the auxiliary positioning device 10 on the corresponding bus duct 60. Figure 4 First, rotate the positioning member 12 relative to the auxiliary member 11 around the pivot 125 to the avoidance position, and then align each rib 1141 with the first groove portion 6401 of the corresponding fixing groove 640 and insert the rib into each first groove portion 6401. Figure 5 After each rib 1141 is inserted into the bottom of the first groove 6401, it moves along the first direction L1 to the bottom of the second groove 6402. The positioning member 12 in the avoidance position does not affect the engagement between each rib 1141 and the corresponding fixing groove 640.

[0084] See also Figure 6 After each rib 1141 engages with the second groove 6402, the positioning member 12 is rotated about the pivot axis XX. When the positioning member 12 is rotated to the working position, the side edges 1241 of the connecting ears 124 abut against the limiting shafts 127, while the second limiting surfaces 122 engage with the ends 621 of the side panels 62 of the bus duct 60, securing the positioning member 12 in the working position. At this point, the auxiliary positioning device 10 is secured to the bus duct 60. The first limiting surface 121 is substantially perpendicular to the ground.

[0085] See also Figure 7 , dock the bus duct connector 70 with a bus duct 60 equipped with an auxiliary positioning device 10, with the positioning member 12 of the auxiliary positioning device 10 in the working position. Before docking, the bus duct connector 70 and the bus duct 60 can be manually aligned in the width direction W. During the docking process, when the flanges 712 on both sides of the end cover 71 of the bus duct connector 70 abut against the first limiting surface 121, it can be determined that the bus duct connector 70 and the bus duct 60 are docked.

[0086] See also Figure 8 , bring the other bus duct 60 equipped with the auxiliary positioning device 10 close to the bus duct connector 70 and align it with the bus duct connector 70, with the positioning member 12 of the auxiliary positioning device 10 in the working position. Then hook the hook portion 211 of the first end of the pull rod 20 with the snap-in groove 1121 of the auxiliary member 11 on one bus duct 60. Next, insert the first end of the driving rod 30 into the socket 1130 of the auxiliary member 11 on the other bus duct 60 after passing through a through hole 220. Apply a first external force to the driving rod 30. According to the lever principle, the two bus ducts 60 are pushed closer to each other by the driving rod 30 and the pull rod 20, and the phase conductor 631 of the other bus duct 60 gradually extends into the bus duct connector 70. During this operation, please note that the opening slots 123 are staggered with the flanges 712.

[0087] It will be understood that in the disclosed embodiment, the two auxiliary positioning devices 10 have the same structure. The hook portion 211 of the pull rod 20 can be hooked with either of the two auxiliary components 11, and the first end of the drive rod 30 can be inserted into the socket 1130 of the other of the two auxiliary components 11. Of course, in some alternative embodiments, the structures of the two auxiliary positioning devices 10 may not be exactly the same. For example, if the first end 21 of the pull rod 20 is pivotally connected to one of the auxiliary components 11 and is not easily disassembled, then the socket 1130 may not be provided on that auxiliary component 11, and the other auxiliary component 11 not pivotally connected to the pull rod 20 may correspondingly not be provided with the engaging groove 1121.

[0088] See also Figure 9 and Figure 10In the process of applying the first external force to the drive rod 30 to pull the two bus ducts 60 closer together, according to the change in the distance between the two bus ducts 60, the first end 31 of the drive rod 30 is appropriately adjusted to be inserted into different through holes 220 until the two side flanges 712 of the end cover 71 of the bus duct connector 70 are clamped between the first limiting surfaces 121 of the two positioning members 12. At this time, under the positioning effect of the two first limiting surfaces 121, even if the installer continues to apply the first external force to the second end 32 of the drive rod 30, the drive rod 30 cannot push the two bus ducts 60 closer to each other. The installer can thus quickly determine whether the entire bus duct assembly is docked in place. Of course, the installer can also visually observe whether the two side flanges 712 of the end cover 71 are clamped between the two first limiting surfaces 121 to assist in determining whether the bus duct assembly is docked in place.

[0089] See also Figure 10 In the disclosed embodiment, the longitudinal distance L3 between the first limiting surfaces 121 of the two auxiliary positioning devices 10 and the ends 621 of the side panels 62 of the corresponding bus duct 60 is equal. This simply positions the bus duct connector 70 and the two bus ducts 60 relative to each other in the longitudinal direction L, ensuring connection quality.

[0090] See also Figure 11 When the bus duct assembly is docked, the driving rod 30 and the pull rod 20 are removed, and then a second external force is applied to the positioning members 12 on each bus duct 60 ( Figure 11 For ease of illustration, one bus duct 60 is omitted. The positioning member 12 is then moved axially along the pivot axis XX until the two open slots 123 align with the corresponding flanges 712 on either side of the end cap 71. At this point, the flanges 712 no longer interfere with the positioning member 12's rotation in direction T2, allowing the installer to easily tilt the positioning member 12 upward in direction T2, moving it out of its working position. The ribs 1141 of the auxiliary member 11 can then be easily removed from the fixing slots 640 of the bus duct 60, allowing the auxiliary positioning device 10 to be removed from the bus duct 60.

[0091] In an embodiment of the present disclosure, when the installer uses the installation tool 100 to leverage the two bus ducts 60, the two bus ducts 60 cannot be brought closer together when the end cap 71 of the bus duct connector 70 is clamped between the first limiting surfaces 121 of the auxiliary positioning device 10 installed on the two bus ducts 60. This allows for quick determination of the proper docking of the bus duct connector 70 and the bus duct 60. The installation tool 100 is particularly suitable for docking bus duct assemblies comprising two or three rows of bus ducts.

[0092] While various embodiments of the present disclosure have been described above, the above descriptions are illustrative, non-exhaustive, and not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
